Tutorial: Climate Change: Challenges for Machine Learning
Despite the scientific consensus on climate change, drastic uncertainties remain. Crucial questions about changes in regional climate, trends of extreme events such as heat waves, heavy precipitation, and mega-storms, and understanding how climate varied in the distant past, must be answered in order to improve predictions, assess impacts and vulnerability, and aid mitigation and adaptation efforts. Machine learning can help answer such questions and shed light on climate change. Similar to the case of bioinformatics, the study of climate change provides a data-rich scientific domain in which cutting-edge tools from machine learning can make a major impact. Further, such questions give rise to new challenges for the design of machine learning algorithms. This tutorial will give an overview of impactful open questions about climate change, highlight recent successes of machine learning in this domain, and outline significant remaining challenges. Machine learning problems in climate change include prediction, reconstruction, causal attribution, analysis of quantiles and extremes, and exploratory data analysis. Challenges arise because the climate system is extremely complex, comprised of physical processes and their interactions, and the data is massive, high-dimensional, and spatiotemporal, with non-stationarity and potential long-range dependencies over time and space.

Webinar: Biodiversity as a metric of ecosystem resilience to climate change
Title: Biodiversity as a metric of ecosystem resilience to climate change Presenter: Helen Poulos, PhD Date: March 13th, 2014 at 11am CST Abstract: Shifting diversity patterns and species turnover are fundamental concerns about how climate change will influence desert ecosystems. Scientists, managers, and-policy makers are searching for metrics to assist in the prediction of ecosystem responses to climate change. Temporal variation in landscape and regional-scale diversity can provide insights on the fragility or resilience of plant and animal communities in the Southwest to changing climates. This talk will explore the suite of diversity metrics and tools for measuring species turnover that are available for monitoring ecosystem change over time through the lens of biodiversity. About the Presenter: Helen's research focuses on developing risk management and decision support tools for sustainable forest and ecosystem management. She has been working in the Southwest for the last 14 years exploring local-, landscape, and regional-scale tree diversity patterns and species turnover along environmental gradients of Sky Island systems. Helen is both a field biologist and a data-mining expert, which she uses for developing decision support tools that can be readily implemented by policy-makers and on the ground by land managers. She holds a Master's degree in Geography from The Pennsylvania State University and a PhD from The Yale School of Forestry and Environmental Studies. She is currently part of Wesleyan University's College of the Environment.

Environment Impact Assessment Part 1
Support us : https://www.instamojo.com/@exambin/ Download our app : http://examb.in/app Environmental Impact Assessment Developmental projects in the past were undertaken without any consideration to their environmental consequences. As a result the whole environment got polluted and degraded. In view of the colossal damage done to the environment, governments and public are now concerned about the environmental impacts of developmental activities. So, to assess the environmental impacts, the mechanism of Environmental Impact Assessment also known as EIA was introduced. EIA is a tool to anticipate the likely environmental impacts that may arise out of the proposed developmental activities and suggest measures and strategies to reduce them. EIA was introduced in India in 1978, with respect to river valley projects. Later the EIA legislation was enhanced to include other developmental sections since 1941. EIA comes under Notification on Environmental Impact Assessment (EIA) of developmental projects 1994 under the provisions of Environment (Protection) Act, 1986. Besides EIA, the Government of India under Environment (Protection) Act 1986 issued a number of other notifications, which are related to environmental impact assessment. EIA is now mandatory for 30 categories of projects, and these projects get Environmental Clearance (EC) only after the EIA requirements are fulfilled. Environmental clearance or the ‘go ahead’ signal is granted by the Impact Assessment Agency in the Ministry of Environment and Forests, Government of India. Projects that require clearance from central government can be broadly categorized into the following sectors • Industries • Mining • Thermal power plants • River valley projects • Infrastructure • Coastal Regulation Zone and • Nuclear power projects The important aspects of EIA are risk assessment, environmental management and Post product monitoring. Functions of EIA is to 1. Serve as a primary environmental tool with clear provisions. 2. Apply consistently to all proposals with potential environmental impacts. 3. Use scientific practice and suggest strategies for mitigation. 4. Address all possible factors such as short term, long term, small scale and large scale effects. 5. Consider sustainable aspects such as capacity for assimilation, carrying capacity, biodiversity protection etc... 6. Lay down a flexible approach for public involvement 7. Have a built-in mechanism of follow up and feedback. 8. Include mechanisms for monitoring, auditing and evaluation. In order to carry out an environmental impact assessment, the following are essential: 1. Assessment of existing environmental status. 2. Assessment of various factors of ecosystem (air, water, land, biological). 3. Analysis of adverse environmental impacts of the proposed project to be started. 4. Impact on people in the neighborhood. Benefits of EIA • EIA provides a cost effective method to eliminate or minimize the adverse impact of developmental projects. • EIA enables the decision makers to analyses the effect of developmental activities on the environment well before the developmental project is implemented. • EIA encourages the adaptation of mitigation strategies in the developmental plan. • EIA makes sure that the developmental plan is environmentally sound and within limits of the capacity of assimilation and regeneration of the ecosystem. • EIA links environment with development. The goal is to ensure environmentally safe and sustainable development. Environmental Components of EIA: The EIA process looks into the following components of the environment: • Air environment • Noise component : • Water environment • Biological environment • Land environment EIA Process and Procedures Steps in Preparation of EIA report • Collection of baseline data from primary and secondary sources; • Prediction of impacts based on past experience and mathematical modelling; • Evolution of impacts versus evaluation of net cost benefit; • Preparation of environmental management plans to reduce the impacts to the minimum; • Quantitative estimation of financial cost of monitoring plan and the mitigation measures. Environment Management Plan • Delineation of mitigation measures including prevention and control for each environmental component, rehabilitation and resettlement plan. EIA process: EIA process is cyclical with interaction between the various steps. 1. Screening 2. Scoping 3. Collection of baseline data 4. Impact prediction 5. Mitigation measures and EIA report 6. Public hearing 7. Decision making 8. Assessment of Alternatives, Delineation of Mitigation Measures and Environmental Impact Assessment Report 9. Risk assessment

Climate Change and Land Management: Social Network Analysis
This webinar was held as a part of the Climate Change Science and Management Webinar Series, a partnership between the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center. Webinar Description: Many federal agencies are currently striving to plan for climate change adaptation. Researchers for this project explored 1) the degree to which federal resource managers believe that climate change adaptation is important in their work and 2) the degree to which these managers are connected to each other and to a broader research community that can provide a scientific basis for climate change adaptation actions. The project consisted of a social network analysis of federal resource managers in the regions encompassed by the Southwest and North Central CSCs. Methods for this project included an online survey targeting resource managers from the Bureau of Land Management, Forest Service, National Park Service and Fish and Wildlife Service, as well as a snowball survey to garner opinions from people within academic, nongovernmental and federal research organizations (e.g., USGS), as well as from state resource managers. This study resulted in a number of different findings, including an overall strong concern for climate change impacts on natural resources among resource managers and a varying degree of connectedness between resource management agencies and research units.

Land Cover Products for Understanding Water Quality Impacts
This webinar originally aired on 27 October 2015. Land use and land cover have significant impacts on ecosystem health—with impervious surface runoff and natural areas that provide flood protection or pollutant filtering being obvious examples. Information on how and where these and other land changes are occurring is essential to understanding the potential impacts from past management practices and choosing the right course of action for the future. NOAA’s Office for Coastal Management’s Coastal Change Analysis Program (C-CAP) provides nationally standardized land cover and change information for the coastal United States. Regional monitoring data are updated every five years. Dates goes back to 1996 or earlier in most locations. Higher-resolution data products provide greater detail for some areas. This presentation will provide an overview of these data sets, show where to find them on the Digital Coast, and highlight several tools that make use of them. These tools include the Land Cover Atlas—an online viewer that allows users to analyze change statistics and maps for their county or watershed of interest—and a new “How-to” that walks users through key land cover indicators of water quality. Learn more at http://coast.noaa.gov/dataregistry/search/collection/info/ccapregional. This webinar was presented by Rebecca Love and Nate Herold of NOAA’s Office for Coastal Management, and it was co-sponsored by MEAM, OpenChannels.org, and the EBM Tools Network.

How to green the world's deserts and reverse climate change | Allan Savory
"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

North American Forest Dynamics Dataset
Forests are living, ever changing ecosystems, affected by aging, natural disasters and human interventions. Annual maps of the lower-48 United States produced from satellite data illustrate how these dynamic systems changed from 1986-2010. Logging and hurricanes play a significant role in the Southeast, and fires and insect invasion damage forest canopy in the West. Trees are one of the world's best absorbers of atmospheric carbon dioxide, a greenhouse gas. Understanding how trees and forests change through time is one of the first steps to understanding how active they are in pulling carbon dioxide out of the atmosphere, which is of profound interest to scientists monitoring climate change. Developed for the North American Forest Dynamics study, scientists combined 25 years of satellite data from the joint U.S. Geological Survey/NASA Landsat satellite program with information from the U.S. Forest Service to highlight where forest canopy was disturbed.

The melting North Pole, is our North Pole too | Maarten Loonen | TEDxVenlo
Maarten has spent every summer for the last thirty years doing research in Svalbard. During this period he has witnessed drastic shifts in the environment. Maarten envisions a world where we can adapt to rapid changes in the environment like global warming. Raising awareness and creating a connection with the north pole is why Maarten wants to talk about these changes and their causes during his TED-talk. Dr Maarten Loonen is a polar researcher who has been travelling to Spitsbergen for over 25 years to study the behaviour of migratory birds and changes in their living conditions. The Polar regions are unique for researchers as rises in temperature and the consequences for humans, animals and plants are extra visible here. On Spitsbergen, Loonen and other Groningen scientists are studying whale hunting, tourism, mining, ecosystems and the consequences of climate change for migratory birds. In 2014, Loonen was one of the researchers of the University of Groningen that were invited by the Dutch Navy to join an expedition to Jan Mayen island. This was a unique opportunity for the researchers to visit this isolated island. The multidisciplinary research team concentrated on archaeology and biology.

Conservation Paleobiology: Contributions to Understanding Climate, Disturbance and Restoration
Andrea Brunelle Professor & Chair, Department of Geography, University of Utah. [email protected] Humans are altering our environment. Climate change resulting from the burning of fossil fuels is documented beyond argument. Landscape modification through grazing, logging, mining and other activities is omnipresent. But what are the actual ecological implications? Can systems recover? Conservation paleobiology is a newly named field for an application of paleoecology. Conservation paleobiology can take a near-time, 2 million years, or deep-time approach but both provide information on ecological responses to climatic variability. The near- time approach presented here more specifically uses paleoecological data to generate pre-and post-disturbance ecological baselines and natural ranges of variability, describes ecosystem response to disturbances - natural and anthropogenic- and helps develop realistic restoration goals. We will examine “lessons learned” from records spanning woody plant encroachment and desiccation in desert wetlands to high elevation forest sites impacted by beetles and forest fires and discuss how conservation paleobiologists can better work with land managers to use these important data. I am an Associate Professor and Chair in the Geography Department at the University of Utah. My BS is in Environmental Science- Geology - and my MS is in Quaternary Studies -Paleoecology- from Northern Arizona University in Flagstaff, Arizona. My Ph.D. is from The University of Oregon in Eugene, Oregon in Physical Geography. My research focuses on reconstructions of past environments from lake and wetland sediments with particular interest in projects with management applications. These projects include reconstructions of fire and vegetation regimes from sedimentary deposits, studying past bark beetle outbreaks in the mountain west, studies of southwestern desert wetlands -ciénegas-, and human paleoecology. My passion is educating students about the science of climate change.

"Become the Voice of Voicless", Ecological Exhibition, 2008
Today Armenia has turned into an ecological disaster zone as a result of the catastrophic impact of the anthropogenic pressure. The wide-ranging and hasty mining activities, mass forest logging (In Armenia approximately 1 million cubic meters of timber, the average of 8000ha of forest, is illegally logged), urbanization, the pollution of rivers and humid areas, poaching and illegal animal trade, the big volumes of fishing have led to the degradation of the environment, climate change, decrease in specie populations and disruption of ecological processes. Hundreds of flora and fauna species have appeared on the brink of extinction. According to the data published by the UN, 82% of Armenia?s territory is under the threat of desertification. Due to the deterioration of the air quality the number of respiratory diseases has doubled, and the number of anomalous births is on the rise, too (According to a 2005 World Health Organization report, Armenia ranks second among CIS countries by anomalous births and similar problems, only Kyrgyzstan is worse off). This gruesome picture of the tormented Mother Nature with all its dreadful consequences must sober the Armenian people. Human indifference cannot be justified either by social situation, or by economic interest or by political strategy. Humans are destroying their only supporting platform; humans have forgotten about nature, humans have stopped loving nature. We, the organizers of the exhibition, are a group of young environmental activists united by our love and caring attitude towards nature. We are doing our best to react to the urgent ecological issues through raising the awareness of the public, developing "environmental mindset" and various other activities. Since 2006 we have organized numerous bicycle campaigns both in Yerevan and outside the capital city which have been aimed at the promotion of bicycle as an environmentally friendly means of transportation as well as at the encouragement of healthy lifestyles. The destruction of a natural monument called Garni's "Stone Symphony" was halted following our effective intervention (bicycle ride to Garni, protest march). In addition, we deal with animal protection issues, we try to combat violence against animals, animal abuse, animal killings, and we fight for animal rights . The most painful and the hottest ecological issue of our days is the outrageous project of launching the exploitation of the Teghut copper-molybdenum minefield. At least 600ha of forest (in other words, 200.000 trees) will be felled as a result of operating the mine. 55.000 rare and 45.000 valuable trees from Teghut forests as well as Red-listed flora and fauna species will once and for all disappear from those areas. Of special concern are the production tailing and their impact that will emerge as a consequence of mine operation. The environment and human health will suffer major losses because of the infiltration of copper, molybdenum, sulfur, zinc, lead and other poisonous metals into the soil, water and air basins. Let us preserve the nature; it is the guarantee of our life and the life of the coming generations, isn't it? Let us not destroy and let others destroy! Let us not pollute and let others pollute! Let us not defile and let others defile MOTHER NATURE? Each and all of us can, have the power and are obliged to be concerned about, take care of, preserve and protect NATURE!

What is ECOLOGICAL FOOTPRINT? What does ECOLOGICAL FOOTPRINT mean? ECOLOGICAL FOOTPRINT meaning - ECOLOGICAL FOOTPRINT definition - ECOLOGICAL FOOTPRINT explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. An ecological footprint is a measure of human impact on Earth's ecosystems. It's typically measured in area of wilderness or amount of natural capital consumed each year. A common way of estimating footprint is, the area of wilderness of both land and sea needed to supply resources to a human population; This includes the area of wilderness needed to assimilate human waste. At a global scale, it is used to estimate how rapidly we are depleting natural capital. The Global Footprint Network calculates the global ecological footprint from UN and other data. They estimate that as of 2007 our planet has been using natural capital 1.6 times as fast as nature can renew it. Ecological footprint analysis is widely used around the Earth as an indicator of environmental sustainability. It can be used to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations. Since 2006, a first set of ecological footprint standards exist that detail both communication and calculation procedures. The first academic publication about ecological footprints was by William Rees in 1992. The ecological footprint concept and calculation method was developed as the PhD dissertation of Mathis Wackernagel, under Rees' supervision at the University of British Columbia in Vancouver, Canada, from 1990–1994. Originally, Wackernagel and Rees called the concept "appropriated carrying capacity". To make the idea more accessible, Rees came up with the term "ecological footprint", inspired by a computer technician who praised his new computer's "small footprint on the desk". In early 1996, Wackernagel and Rees published the book Our Ecological Footprint: Reducing Human Impact on the Earth with illustrations by Phil Testemale. Footprint values at the end of a survey are categorized for Carbon, Food, Housing, and Goods and Services as well as the total footprint number of Earths needed to sustain the world's population at that level of consumption. This approach can also be applied to an activity such as the manufacturing of a product or driving of a car. This resource accounting is similar to life-cycle analysis wherein the consumption of energy, biomass (food, fiber), building material, water and other resources are converted into a normalized measure of land area called global hectares (gha). Per capita ecological footprint (EF), or ecological footprint analysis (EFA), is a means of comparing consumption and lifestyles, and checking this against nature's ability to provide for this consumption. The tool can inform policy by examining to what extent a nation uses more (or less) than is available within its territory, or to what extent the nation's lifestyle would be replicable worldwide. The footprint can also be a useful tool to educate people about carrying capacity and overconsumption, with the aim of altering personal behavior. Ecological footprints may be used to argue that many current lifestyles are not sustainable. Such a global comparison also clearly shows the inequalities of resource use on this planet at the beginning of the twenty-first century. In 2007, the average biologically productive area per person worldwide was approximately 1.8 global hectares (gha) per capita. The U.S. footprint per capita was 9.0 gha, and that of Switzerland was 5.6 gha, while China's was 1.8 gha. The WWF claims that the human footprint has exceeded the biocapacity (the available supply of natural resources) of the planet by 20%. Wackernagel and Rees originally estimated that the available biological capacity for the 6 billion people on Earth at that time was about 1.3 hectares per person, which is smaller than the 1.8 global hectares published for 2006, because the initial studies neither used global hectares nor included bioproductive marine areas.

The Anthropocene: The age of mankind - Docu - 2017
An ocean that contains as much plastic as fish, an atmosphere filled with CO2 choking the whole mankind and mass extinction of animals. The destructive influence of mankind will be at least as disastrous as the asteroid element that wiped the dinosaurs off the planet. Reason for Dutch scientist Paul Crutzen to introduce a new geological period: the Anthropocene, or the age of mankind. Original title: Tijdperk van de mens German explorer Alexander von Humboldt (1769-1859) was one of the first to see how everything in an ecosystem is connected. Von Humboldt introduced the idea of ​​the Earth as a living organism in Western thinking, which eventually became the basis for the later environmental movement. Geologists from now see the impact of mankind at an increasing pace: climate warming, plastic soup, nuclear fallout, a disturbed water supply through erosion and tar sands, higher CO2 concentrations and diminishing biodiversity. During the last century, the influence of mankind on our Earth and atmosphere has become so great that it is judged by some scientists to be irreversible. To name this influence, a group of geologists recently proposed to date the Anthropocene back to 1950, with the exponential growth of the fossil economy. But earlier it was also discussed that the beginning of the industrial revolution was the starting point, or the first forms of agriculture or even the first mining in the Stone Age. The influence of mankind on the Earth is so great that next generations will be able to see it back in the Earth's layers over hundreds of thousands of years. But if mankind really creates its own geological period, how can we deal with it in an adult way without reliance on a naive belief such as the self-solving ability of God or nature? How can mankind take responsibility and benefit from its influence? We are also finding solutions for climate change and depletion of our mineral resources here on Earth: from the cultivation of cucumbers in the desert, the mining of platinum into the space to the regreening of eroded land. Are these breakthrough just a bandaid on an hemorrhage or can mankind shape the Anthropocene by means of technological intervention so that we meet a viable future? With: Andrea Wulf (historian and author of 'The Inventor of Nature', a biography of explorer Alexander von Humboldt), Bruno Latour (philosopher associated with Sciences Po in Paris and author of, among others, Facing Gaia. Eight Lectures on the New Climatic Regime ') and Phil Gibbard (British geologist setting up a working group to see if the Anthropocene can be introduced as an official geological term).

What is AQUATIC BIOMONITORING? What does AQUATIC BIOMONITORING mean? AQUATIC BIOMONITORING meaning - AQUATIC BIOMONITORING definition - AQUATIC BIOMONITORING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Aquatic biomonitoring is the science of inferring the ecological condition of rivers, lakes, streams, and wetlands by examining the organisms that live there. While aquatic biomonitoring is the most common form of such biomonitoring, any ecosystem can be studied in this manner. Biomonitoring typically takes different approaches: Bioassays, where test organisms are exposed to an environment to see if mutations or deaths occur. Typical organisms used in bioassays are fish, water fleas (Daphnia), and frogs. Community assessments, also called biosurveys, where an entire community of organisms is sampled, to see what types of taxa remain. In aquatic ecosystems, these assessments often focus on invertebrates, algae, macrophytes (aquatic plants), fish, or amphibians. Rarely, other large vertebrates (reptiles, birds, and mammals) are considered as well. Online biomonitoring devices, using the ability of animals to permanently taste their environment. Different types of animals are used for that purpose either under lab or field conditions. The use of valve opening/closing activity of clams is one of the possible ways to monitor in-situ the quality of freshwater and coastal waters. Aquatic invertebrates have the longest history of use in biomonitoring programs. In typical unpolluted temperate streams of Europe and North America, certain insect taxa predominate. Mayflies (Ephemeroptera), caddisflies (Trichoptera), and stoneflies (Plecoptera) are the most common insects in these undisturbed streams. In rivers disturbed by urbanization, agriculture, forestry, and other perturbations, flies (Diptera), and especially midges (family Chironomidae) predominate. Aquatic invertebrates are responsive to climate change. Aquatic Biomonitoring is important in monitoring marine life and their ecosystems. Monitoring aquatic life can also be beneficial in understanding land ecosystems as well. Before there were tetrapods, there were fish. These fish then evolved into tetrapods that we see today. Because of this, aquatic life still has a major impact on life on land. Aquatic biomonitoring can represent the overall health and status of the environment, detect different environmental trends and how different stressors will affect those trends, and interpret the affect of different environmental activity will have on the overall health of the environment. Pollution and general stresses to aquatic life can have a huge impact on the environment in general. The main sources of pollution to oceans, rivers, and lakes are sewage, oil spills, land runoff, littering, ocean mining, and nuclear waste. These types of pollution cause a huge upset to marine life and can endanger any species in the water or that live close to the water. When aquatic species are affected, it causes a ripple effect. Many aquatic animals are a main food source for many land animals. For example: if a specific species of fish ingest toxins and become sick, the birds that ingest that species of fish will also become sick. Then the animal that ingest that bird will also become sick. This is a problem that can be avoided by monitoring all life and conditions in different bodies of water, including fresh and salt water. The main draw back on aquatic biomonitoring is simplifying data and making data easier for all to understand. Taking data from monitoring sites and making it available for people to use in the health fields and other environmental fields can be a challenge. Mechanisms that are used for Aquatic Biomonitoring are monitoring and assessing aquatic species and ecosystems, monitoring the behavior of certain aquatic species and assessing any changes in species behavior, and looking at contaminants in the water and their effect on marine life. Water is graded on several scales. One is the water’s appearance. Is the water clear, cloudy, full of algae. Next, water is graded on its chemistry levels. How much of each enzyme or mineral located in the water is extremely important. Any changes in any of these factors can change the water’s environment overall and therefore change how life in the water is.

Uncertainty in Hydrological and Water Resource Modelling
This talk begins with an overview of the properties of hydrological and water resource models then charts the history of their use inclimate risk assessment at the catchment-scale. Concepts such as equifinality in (hydrological) modelling and associated implications for climate impact assessment will then be explored. Uncertainties linked to hydrological model structures and parameters are placed in the wider context of other major uncertainties arising from non - climatic pressures, climate model and downscaling biases. Explanations for apparent mismatches between observed and expected hydrological change at regional scales will be offered. Two case studies will then demonstrate how models can be used as ‘virtual laboratories’ for exploring multiple working hypotheses about hydrological change (in the Boyne, Republic of Ireland), and for assessing outcomes of adaptation options (in the Upper Colorado, USA). The talk will conclude with a summary of outstanding research challenges and explain how these relate to the information needs of water planners.

Global Forest Link: Engaging Youth Worldwide
Session# 67 Mon 22 October 16:30 to 17:30 1 hr Room 1 GoToWebinar.com 854‐927‐907 Webcast URL https://attendee.gotowebinar.com/register/2539419254691109635# Abstract Global Forest Link (globalforestlink.com, GFL), an award‐winning environmental program, engages youth worldwide in active protection of the environment, with the goal of creating a more sustainable future. Forests are extremely important for human health, climate change mitigation, water purification, and for communities’ resilience and sustainability. Forest health monitoring and management require international collaboration, increased awareness of forest threats, a better understanding of forest processes, and practical skills in analyzing and communicating forest information. Initially developed as an education extension of the WRI’s Global Forest Watch platform, the Global Forest Link project has brought together over 1800 students from 100+ schools and youth groups, and 7 countries. Its key objective is to nurture a new generation of world stewards, who are skilled in modern earth observation technologies, data collection and analysis, evidence‐based education, international collaboration, environmental advocacy, and journalism. GFL teaches youth to explore key environmental change issues by integrating space imagery and local data, understand environmental and socio‐economic consequences of forest degradation, and to communicate their findings to peers and communities. These are important skills needed by future environmental advocates capable of formulating and promoting coordinated strategies and solutions to problems that require global cooperation. GFL addresses the UN 2030 Sustainable Development Goals, focusing on Goals 4 (ensure inclusive and equitable education), 13 (combat climate change and its impacts), and 15 (promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss). The project advances best education practices and promotes equitable access to information. GFL methodology and activities lower the barrier to engagement and enable environmental advocacy by youth around the world. The GFL interactive portal provides effective mechanisms for collection, analysis and sharing environmental and social information.

Big Data for Biodiversity, Australia
In 2014, the team at Western Australia Iron Ore identified that digital innovation could help enhance environmental outcomes and developed the Big Data for Biodiversity project. The project provided a landscape-scale, cumulative impact assessment of BHP Iron Ore’s ‘Life of Asset’ plan. The team developed a user-friendly tool that provided a quantitative assessment across various temporal scales, spanning approximately 100 years of operating life. This information is helping the business to make informed decisions now because they have the ability to begin with the end in mind. By taking a ‘big picture’ approach, the project team has been able to quantify the key potential impacts that are most important on a regional scale. They found that the biggest potential threats to protected species were grazing and climate change, and have made their results publicly available to help assist governments, communities and industry, and effectively protect our country’s significant flora and fauna species.

The Third Industrial Revolution: A Radical New Sharing Economy
The global economy is in crisis. The exponential exhaustion of natural resources, declining productivity, slow growth, rising unemployment, and steep inequality, forces us to rethink our economic models. Where do we go from here? In this feature-length documentary, social and economic theorist Jeremy Rifkin lays out a road map to usher in a new economic system. A Third Industrial Revolution is unfolding with the convergence of three pivotal technologies: an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet, all connected to the Internet of Things embedded across society and the environment. This 21st century smart digital infrastructure is giving rise to a radical new sharing economy that is transforming the way we manage, power and move economic life. But with climate change now ravaging the planet, it needs to happen fast. Change of this magnitude requires political will and a profound ideological shift.

Spatio Temporal Analysis of Socioeconomic Neighborhoods | SciPy 2018 | Rey, Knapp, Wolf...
The neighborhood effects literature represents a wide span of the social sciences broadly concerned with the influence of spatial context on social processes. From the study of segregation dynamics, the relationships between the built environment and health outcomes, to the impact of concentrated poverty on social efficacy, neighborhoods are a central construct in empirical work. From a dynamic lens, neighborhoods experience changes not only in their socioeconomic composition, but also in spatial extent; this latter source of change, however, has been largely neglected in the extant literature. In this paper, we discuss the development of novel, spatially explicit approaches to the study of longitudinal neighborhood dynamics using the scientific Python ecosystem.

Assessing palaeochannel resources in the light of future environmental change
Assessing palaeochannel resources in the light of future environmental change: a case study from the Trent Valley, UK David Knight, Samantha Stein, Steve Malone YORK ARCHAEOLOGICAL TRUST Palaeochannels are one of the most common features of valley floors in temperate alluvial landscapes, and their value as natural sediment traps containing proxy records of climate, vegetation history and land-use is well known within the archaeological and geomorphological communities. In the recent past, the most significant threats to these landforms have been associated with quarrying, but future climate change may bring new challenges, associated both with changing natural threshold conditions and with flood risk management. Mitigating and managing future threats to these important historic environment assets requires detailed knowledge of their extent and character. This paper outlines a multi-staged approach to evaluating the palaeochannel resource in the Nottinghamshire sector of the middle and lower Trent Valley, UK. The first stage of the project involved the mapping of features from a variety of remote-sensed imagery, including standard aerial photography, lidar and multispectral data, and assessing the efficacy of each methodology. However, producing a landform resource map is simply the first stage of this project, and this presentation will also explore future stages, including fieldwork strategies for assessing the chronology and preservation potential of these landforms at the macroscale and likely future threats associated with climate change. Whilst such research is important for heritage management, this approach can benefit the wider community. In particular, palaeochannels are key assets for nature conservation, and can play a key role in flood management strategies as a part of Sustainable Urban Drainage Systems.

In just two days, a mile long block of ice split from Antarctica’s Pine Island Glacier and dropped into the sea. This is the fastest melting glacier in Antarctica. These so-called calving events are increasing as the West Antarctic Ice Sheet’s slide into the ocean accelerates. Infrared sensors make the forests of China red in this image showing the Yangtze River before and after the completion of the Three Gorges Dam in 2012. Construction of the Dam — which you can see in the bottom righthand corner — forced over one million people to relocate, and triggered 3,400 earthquakes. The effects of thirty years of coal mining in Wyoming’s Power River Basin are seen here. This area produced 22 percent of the U.S. coal supply in 2014, but USGS officials estimate that these mines have less than 20 years of recoverable coal remaining. Looking North to Greenland’s ice sheet, we see the exceptionally early melting that is now taking place. Melting encourages more melting when ponds develop by darkening the surface, absorbing more sunlight than ice does. That meltwater also creates and flows through crevasses to the base of the glacier, speeding up ice flow. In Kamchatka, an unusually warm, dry winter contributed to a massive wildfire that burned nearly 600,000 acres in a matter of weeks. Not only is the fire glowing orange in the 2016 image, but you can also see where the blaze was naturally contained by rivers to the east and west. In the 25 years between when these two images of India’s sprawling capital were taken, its population nearly tripled from 9.4 to 25 million and is now second only to Tokyo. Delhi is expected to have 37 million residents by 2030. On a plateau 18,670 feet in the Peruvian Andes we find Qori Kalis, the largest glacier in the world’s largest tropical ice cap. In 1978 it was still advancing, but 41 years later it had retreated dramatically, leaving behind a 60 meter deep lake. Switching gears, we see the explosion of the shrimp farm industry on the western shoreline of Sonora, Mexico. While it has created profits and jobs in this arid region, concerns have arisen about its effect on the ecosystem and over property rights to communal coastal lands. A continuous drought has taken its toll on the American southwest. Texas’ Lake Meredith is just a fraction of what it was in 1990, causing much of what little vegetation there was in the region to continue dying off. And in Iowa we see the effects of near-record flooding along parts of the Missouri River. After a winter of heavy snow and rain, dams in Montana and Dakota were forced to send record amounts of water into the floodplain, causing levees downstream to fail, inundating communities like Hamburg. I hope you found this tour of our beautiful, ever-changing earth interesting. Until next time, for TDC, I’m Bryce Plank.

However, a quarter of the world’s land mass is seriously degraded from centuries of deforestation, overgrazing, over exploitation, the building of infrastructure and pollution. Wars and migration are consequences of these problems. Tonight, the film maker and ecologist John Liu will tell the story of how a degraded area in China the size of the Netherlands was successfully restored in a short time. He will explain why landscape restoration matters to all of us, why it needs urgent implementation and how we can be inspired and empowered to contribute to this restoration effort in our own way. ____________________________________ More detailed information: The Great Work of Our Time At certain times in human history the generations alive at the time are called upon to perform heroic deeds. Imagine the transition from “Flat Earth” to “Round Earth” or the end of slavery. Today, we face just such a moment. Human progress and possibly human survival depend on our understanding and actions at this time. Problems like land degradation, biodiversity loss, toxic pollution and climate change affecting everyone have been sublimated for the short-term profit of a few. Human population is growing by one billion people every twelve years. Yet for all our problems, the conditions are ripe for humanity to move to a new level of consciousness. If we realize, that knowledge and generosity yield much better outcomes than ignorance and greed, we can work together for mutual benefit. It is possible to restore large-scale degraded landscapes. It is possible to restore ecological function. We now have the technology to make the sum of human knowledge available to every human being on the planet simultaneously and instantaneously. We are called to restore the Earth and the Human Spirit. This is the Great Work of our Time. Tonight the film maker and ecologist John D. Liu will share what led him to this vision. It began with John filming the process of restoring a degraded area of land the size of The Netherlands in China. Millennia ago this region was very fertile, lush with vegetation, providing the rising Chinese dynasties with vast natural resources to build their empires. Over the centuries, the Chinese used up these resources unsustainably while unaware that it was their own actions that eroded a once green landscape into a ‘moon like’ landscape, causing loss of biodiversity, poverty and famine. John shows how it has been possible to restore this large-scale damaged ecosystem in a very short time. The soil was rebuilt, biodiversity came back, while farmers were able to triple their income and hope and inspiration returned to the communities. John, the farmers, the Chinese government and the financer, the World Bank, were astounded by the success. People around the world started inviting John to communicate his experiences, so they could create similar projects. Several examples of how these are progressing will be shared in this presentation. John will also show how the Commonland Foundation has seen that landscape restoration is not only beneficial to the soil and biodiversity, to the farmers, but how this process can provide a profitable return on investment for businesses. Business cases are being developed to move from a centuries old landscape degradation industry to a landscape restoration industry. It is a win-win situation for Earth and humans alike. Various actions by individuals and communities around the world show how all of us can contribute to this: whether it is in policy making, business or doing projects in our city or even our back yard. All efforts matter and are needed urgently. Finally, John will show how landscape degradation is a root cause of conflict and migration, of which the effects are now being felt in the world today. Landscape restoration is a powerful tool to tackle this problem. This evening is a wake up call. But more importantly it is a message of hope, inspiration and empowerment.

SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ Organisms of all shapes and sizes synchronize their behaviors using biological clocks. Some keep pace with the daily rising and setting sun using circadian rhythms. Others use annual cycles or the changing seasons as their cue. But many animals use moonlight and Earth’s lunar cycle to run their biological clock. Do humans do the same thing, with things like menstrual cycles? This week we take a look at living by moonlight.

Climate Change Threatens Tibet Glaciers
The glaciers on China's Qinghai-Tibet Plateau are quickly disappearing. As a result of climate change, more than 100 square miles have vanished over the past 40 years, according to Chinas state-run media. Liu Faming has been working at the ecosystem observation station on the plateau's Gongga Mountain for 15 years. His daily work is collecting data on air temperature, humidity, wind force, rainfall and the earth's temperature. [Liu Faming, Mt. Gongga Ecosystem Observation Station]: (male, Chinese) "The temperature has gone up in recent years. It is getting warmer and warmer. It used to be really cold in the mountains, but it's very warm now. The glaciers are retreating." Gongga Mountain stands almost 25-thousand feet above sea level, while Hailuogou Glacier, the biggest on the mountain, has become a hot tourist destination. A cable car ride takes curious tourists to an ice fall every day, but for locals like Wang Jun, its beauty has changed over time. [Wang Jun, Villager]: (male, mandarin) "The city gate-shaped part of the glacier is gone. The glaciers are melting slowly day by day. The weather has changed a lot. The temperature remains more or less the same throughout the year. It is not cold in winter anymore. There used to be a lot of ice in winter, but not any more." Scientists from China's Institute of Sciences say the Hailuogou glacier has receded by 20 meters on average every year since 1990, with the speed accelerating in recent years. China has overtaken the U.S. as the world's top emitter of human-generated greenhouse gases, with eyes on how it will address eco-policy ahead. A United Nations climate report released in 2007 suggested action by China and other nations may be essential, with Himalayan glaciers possibly disappearing by the year 2035 or even earlier.
