Sociology and de-growth; social change, entropy and evolution in a way-down eraGoteo / Platoniq
The document discusses the concept of a steady-state economy and debates whether sustainable development or degrowth is a better approach to achieving it. It notes that while both could lead to a steady-state under carrying capacity, degrowth may be inevitable given environmental limits. The discussion explores human evolution under conditions of scarcity, historical evidence of societal collapses, and different philosophical perspectives. Governance challenges of sustainability in a complex system are also covered.
The document discusses limits to growth and sustainability. It summarizes views that once collapse was unthinkable but is now entering public discourse. It also shows that ecosystem services are declining and the world ecological footprint exceeds what is sustainable. The rest of the document discusses debates around sustainable development versus degrowth approaches, and human evolution, historical evidence, and the prospects for an orderly versus chaotic decline in societies that have exceeded ecological limits.
The document summarizes the second phase of the Economics of Ecosystems and Biodiversity (TEEB) Initiative. It provides background on TEEB, recaps the results and impacts of phase 1, and outlines the ambitions, activities, content, and process for phase 2. Phase 2 will broaden the scope of studies to additional ecosystem services and biomes, focus on products for end-users like policymakers, and involve more experts and organizations. The COPI study conducted in phase 1 found that biodiversity and ecosystem losses between 2000-2050 could result in welfare losses of over $14 trillion by 2050. Phase 2 aims to further analyze and communicate the economic benefits of protecting nature.
The document discusses drought events and their assessment in global loss databases. It presents information on Munich Re's NatCatSERVICE database, including its assessment of drought losses worldwide from 1980-2011.

Ecosystem services - the Climbeco critiqueSarah Cornell
Here are a few thoughts on ecosystem services:
- Ecosystem services does not necessarily have to be about money. The original concept focused more broadly on the benefits humans receive from nature. Monetary valuation is one approach, but not the only way to assess value.
- Defining ecosystem values in monetary terms has both benefits and limitations. It can help raise awareness and influence policymakers, but also risks reducing nature to an economic commodity. Non-monetary approaches are needed to capture aspects like cultural, spiritual or intrinsic values.
- Alternative approaches to valuation include deliberative methods like citizens' juries that incorporate social and ethical considerations. Multi-criteria analysis can also integrate monetary with non-monetary indicators. Indigenous and traditional knowledge

Improvement of Text Summarization using Fuzzy Logic Based MethodIOSR Journals
The document describes a method for improving text summarization using fuzzy logic. It proposes using fuzzy logic to determine the importance of sentences based on calculated feature scores. Eight features are used to score sentences, including title words, length, term frequency, position, and similarity. Sentences are then ranked based on their fuzzy logic-determined scores. The highest scoring sentences are extracted to create a summary. An evaluation of summaries generated using this fuzzy logic method found it performed better than other summarizers in accurately reflecting the content and order of human-generated reference summaries. The method could be expanded to multi-document summarization and automatic selection of fuzzy rules based on input type.

This document evaluates the DNDC model's ability to predict nitrous oxide emissions from Irish agriculture by comparing modeled outputs to field measurements from a spring barley field and grazed pasture. For the barley field, modeled fluxes matched measured fluxes well for high fertilizer inputs but underestimated fluxes from low/zero fertilizer treatments. For the pasture, modeled fluxes overestimated emissions due to overestimating the effect of soil organic carbon. Sensitivity analysis found temperature to be the main determinant of emissions. The model predicted increases in emissions of 30-60% for the barley field and 20% for pasture by 2061-2090 due to climate change.

2. It identifies key threats from climate change facing different regions, including tropical storms, flooding, drought, and temperature increases.
3. Main areas of action promoted include improving data and knowledge, disaster risk management, sustainable land and resource management, and policies/financing for adaptation. Regional cooperation, governance, and climate-smart agriculture are emphasized.
This report assesses vulnerability to climate change in Western Honduras. It finds that temperatures have increased rapidly in recent decades and are projected to rise about 2°C by 2050 according to climate models. Precipitation trends vary widely by region, with some areas experiencing increases while others see declines. Models project precipitation could decrease by 10-20% by 2050. This would significantly impact ecosystems and livelihoods in the region. The report analyzes climate exposure and sensitivity of ecological and social systems, including agriculture, across 8 sub-watersheds. It identifies adaptation options to strengthen resilience of livelihoods and ecosystems to climate impacts.
This document summarizes the findings of a vulnerability assessment conducted in 6 coastal villages in Pangani District, Tanzania. The assessment examined how local livelihoods are threatened by climate change as well as other non-climate stressors. Key climate change threats identified include more unpredictable rainfall patterns, increased storms, sea level rise, higher temperatures, and ocean acidification. The assessment found that local livelihoods dependent on agriculture, fishing, and other coastal resources are sensitive to these climate impacts. Non-climate stressors like deforestation, overfishing, and water issues further exacerbate vulnerabilities. The report recommends planning adaptation actions to improve community resilience and reduce vulnerabilities to current and future climate change impacts.
The document summarizes proceedings from a workshop on climate change for civil society organizations in Andhra Pradesh, India. It discusses how watershed development projects can integrate climate change concerns by promoting adaptation strategies. Presentations covered the science of climate change, national climate plans, and the role of CSOs. Participants learned how to build capacity for climate action and prepare communities for impacts through activities like improved natural resource management and migration support. The workshop aimed to help CSOs address climate change in their work.
This document discusses the critical connection between water security and ecosystem services. It begins by introducing the concepts of sustainable development, ecosystem services, and the Millennium Ecosystem Assessment. It then explores the ecosystem approach to water resources management and the role of freshwater resources in supporting human activities and ecosystem functions. The document presents several case studies that demonstrate lessons learned about habitat rehabilitation, pollution control, environmental flows, stakeholder involvement, and integrated watershed management in achieving both water security and sustainable ecosystem services. It concludes by recommending various response options to promote the management of balanced ecosystem services and water security.
Role of Protected Areas in meeting Climate Challenge and IUCN- Saadullah Ayazsaadayaz
Protected areas play an important dual role in addressing climate change through mitigation and adaptation. They mitigate climate change by capturing and storing carbon from the atmosphere in ecosystems. They help adapt to climate change by maintaining ecosystem services that buffer impacts and support livelihoods as climates change. International organizations like IUCN and conventions like the UNFCCC and CBD recognize the role of protected areas in climate strategies and call for increased protection of natural areas to respond to climate challenges.
This document summarizes the scientific evidence on ecosystem-based adaptation (EBA). It presents six major ways that forests and trees can help human adaptation to climate change: 1) provision of products, 2) support of agriculture, 3) management of watersheds, 4) protection of coasts, 5) regulation of cities, and 6) influence on regional climate. The document discusses opportunities and challenges of EBA, including its consideration in national climate adaptation policies and programs. It analyzes examples and case studies of EBA interventions while also acknowledging knowledge gaps and uncertainties regarding some ecosystem services.
Indigenous and Traditional Peoples and Climate ChangeDr Lendy Spires
This document discusses the vulnerability of indigenous and traditional peoples to climate change. It provides an overview of how these communities are impacted based on their social and biophysical vulnerability factors. Specific case studies from the Arctic, Bangladesh, Borneo, Cameroon, Congo, Honduras, Nicaragua and India are examined to illustrate the cultural risks and adaptation strategies employed. The document concludes that indigenous peoples are disproportionately affected by climate change and urges increased consideration of their needs in climate policy.
The document discusses community climate change adaptation concepts and applications. It aims to provide an overview of community climate change adaptation, identify resources and partnerships needed to strengthen climate programming, delineate policies to improve community participation and resilience, and acknowledge challenges and pathways. It discusses key concepts like climate change impacts, community-based adaptation, climate-smart agriculture, and the role of extension services. It outlines methodologies, background on climate impacts and adaptation, and highlights challenges like uncertainty and deficits in adaptive capacities. Overall, the document presents a framework for community climate change adaptation through approaches like integration into development planning, capacity building, knowledge sharing, and education.
This document analyzes trends in ecological footprints in the Mediterranean region. It is a collaboration between Global Footprint Network, WWF Mediterranean, UNESCO Venice, Plan Bleu, and others. The document finds that the ecological footprints of Mediterranean nations now exceed the region's biocapacity by over 150%. Addressing ecological deficits and reducing fossil fuel dependence will help countries combat climate change and become more economically resilient by managing biocapacity and reducing demand on natural resources. Taking action now will be less costly than waiting, as countries can build economies that work with nature instead of against it.
WWF Study: Vulnerability analysis of the amazon biome ClimateCourse
This document provides an analysis of climate vulnerability in the Amazon biome and its protected areas. It begins with an overview of climate change impacts on the region, including increasing temperatures, more frequent droughts and floods, and increased forest fires. It then presents a conceptual framework for assessing climate risks and resilience. The methodology assesses exposure to climate hazards, climate risks to ecosystem services, and factors that build ecosystem resilience. Key findings include increased temperature across the biome, spatially variable drought and flood impacts, and concentration of fires in deforestation fronts. The analysis aims to support climate adaptation and resilience building in Amazon protected areas.
Within the framework of the 1992 UN Conference on Environment and Development, Canada announced an initiative to convert official development aid debt in Latin America into local currency funds for environmental and sustainable development projects. In 1993, agreements were signed between Canada and Colombia to implement this initiative, with ECOFONDO established to administer project financing. A total of 172 projects were funded between 1994-2003 across three thematic areas: environmental management in wild areas and biodiversity; environmental management in agroecosystems; and urban environmental management. The projects achieved a variety of environmental, social, and economic results and impacts, demonstrating that conservation and development goals can be mutually reinforcing when community needs are prioritized.
Assessing climate risk and vulnerabilityNAP Events
The document discusses objectives of national adaptation plans (NAPs) and the global goal on adaptation in the Paris Agreement. It aims to (1) reduce vulnerability to climate impacts by building resilience, and (2) integrate climate adaptation into policies and development planning. The global goal is to enhance adaptive capacity, strengthen resilience, and reduce vulnerability to climate change, contributing to sustainable development. The document also provides examples of assessing risks to water supply systems and crop production in Africa from climate change and how adaptation strategies can help reduce these risks.
This document provides definitions and terminology for concepts related to disaster risk reduction and management (DRRM) and climate change (CC) according to Philippine law and United Nations frameworks. It aims to help participants understand and properly apply these terms. The document defines key terms like hazard, vulnerability, capacity, prevention, mitigation, adaptation, and more. It also distinguishes between DRRM and CC, and explains the objectives of DRRM. Participants will use their understanding of these concepts to formulate a DRRM-CCAM plan for schools.
This document discusses how protected areas can help address global challenges like climate change. It outlines how protected areas store and capture carbon, enhance ecosystem resilience, and provide essential services. The document then discusses how to better design protected area systems to be ecologically representative and well-connected. It also emphasizes the need for improved management capacity, governance, and financing to effectively manage protected areas. The overall message is that protected areas can play a key role in climate change mitigation and adaptation if they are better integrated into land use planning and protected area networks are expanded and better managed.

The study found that the efficiency of tropical forests to absorb carbon dioxide is diminished by global warming. As temperatures increase, trees absorb less carbon due to decreased photosynthesis and increased soil microbe respiration. The researchers analyzed data from 1958 to 2011 and found that for every temperature increase, tropical forests absorb less carbon. This has implications for how forests may respond to continued warming in the future.
President Barack Obama spoke about the need to act on climate change, citing scientific evidence that the last 15 years have been the warmest on record and that rising carbon dioxide levels are disrupting the climate. He noted impacts such as more extreme weather events, rising sea levels contributing to destruction from storms like Hurricane Sandy, and worsening droughts and wildfires. Obama called the costs of these events enormous in terms of lives lost and economic impacts. The newsletter reported on other science and environmental stories, including progress in repairing spinal cord injuries, new maps highlighting global conservation priorities, research finding less mental decline in people reaching age 90 than a decade ago, a large iceberg breaking off an Antarctic glacier, and a study finding some
The document discusses several topics:
1. Research from New York University found that stem cells under fingernails can regenerate nails and bone. The stem cells respond to chemical signals to develop new nail tissue and attract nerves to promote regeneration.
2. A study showed rice husks naturally contain silicon nanoparticles that can be easily extracted and used in lithium-ion batteries. The simple process provides a low-cost way to produce silicon nanomaterials for batteries from a rice farming byproduct.
3. Extracting silicon nanoparticles from rice husks could provide developing countries that produce large amounts of rice an opportunity to add value to the husks and use them in battery manufacturing.
Aves Uruguay, a conservation NGO in Uruguay, plans to launch an Observatory of Natural Grasslands to monitor the country's main natural ecosystem of grasslands. The organization is concerned about the rapid disappearance of grasslands due to increased crop cultivation and afforestation. The Observatory will incorporate new technologies to assess grassland conservation in Uruguay and provide services to other regions through collaborations with sustainable agriculture groups. It aims to reward farmers protecting grasslands and promote 'Grassland Beef' certified through protocols ensuring environmental protection and wildlife conservation.
Researchers have identified a gene pattern associated with autism by studying rare genetic mutations in people with autism and their families. They found disruptions in the same 100 to 200 genes in over 10% of people with autism or developmental delay. This gene pattern provides a new path for understanding the causes of autism and potentially developing targeted treatments.
The document discusses three topics related to conservation:
1) A decline in biodiversity of farmed plants and livestock is threatening future food supplies as only 30 crops account for 95% of calories and 22% of livestock breeds are at risk of extinction. Preserving genetic diversity is important for adapting to climate change.
2) Canaima National Park in Venezuela protects unique table mountain formations and is habitat for diverse wildlife, though under threat from resource extraction. The park is also important for hydroelectric power and inhabited by indigenous Pemón people.
3) The illegal wildlife trade is a lucrative $8-20 billion industry, driving poaching of rhinos and elephants for traditional medicine and ornamental demand in Asia. This dec
The document summarizes news from South America related to environment, science, technology, and health. It discusses experts calling for better monitoring and inclusion of water in development goals due to threats from human activities like dams and irrigation altering the global water system. It also reports on a conference in Germany bringing together water researchers to inform policy on water governance. Additionally, it notes a regional project cataloging humpback whales led by Chilean scientists and participation of local fishermen in ecotourism.

The document provides recommendations to the President for developing a climate change strategy. It suggests focusing on: 1) national preparedness for climate impacts, 2) continuing efforts to reduce carbon emissions with an initial focus on the electricity sector, 3) leveling the playing field for clean energy technologies, 4) sustaining research on next-generation clean technologies, 5) establishing international leadership on climate change, and 6) conducting an energy review. Specific actions recommended include establishing a climate preparedness commission and having agencies create annual preparedness plans.
Facing climate change sustainable energy solutions moving forwardESTHHUB
This webinar will address sustainable energy solutions and be hosted by two ECPA Senior Fellows, Dr. Daniel Kammen and Jeff Soule, on April 19th from 1-2pm EST. Dr. Kammen is a professor of energy at UC Berkley and directs several research centers. Mr. Soule is the Director of Outreach at the American Planning Association and has expertise in urban planning and climate change strategies. The Fellows will present on their expertise and trips sponsored by ECPA, and the audience can ask questions to create a collaborative dialogue on uncertainties, concerns or solutions regarding sustainable energy.
California passed the Global Warming Solutions Act of 2006 (AB32) to reduce greenhouse gas emissions and combat climate change. The Act established mandatory caps on emissions beginning in 2012 and targeted a reduction to 1990 levels by 2020. Despite initial opposition from industry, the policy has boosted the economy through energy efficiency, renewable energy, and green jobs. California's leadership has inspired over half of U.S. states to take climate action and reduced overall U.S. emissions. The state has also influenced international climate policies and hosted global summits. Voters further supported AB32 by defeating an initiative to suspend it until unemployment dropped, showing support for a green economy and environment.
This document summarizes two approaches to climate change partnerships: the global-to-local approach and the international collaboration approach. The global-to-local approach involves partnerships between global organizations and local communities to generate innovative, grassroots solutions. The international collaboration approach leverages partnerships between organizations worldwide to quickly share knowledge and accelerate innovation. Both approaches are illustrated through case studies of existing partnerships addressing issues like clean energy, sustainable tourism, agriculture, and off-grid power solutions.

T
he Eastern Cordillera Real (ECR) is one of the most biologically and
culturally diverse ecoregions in the whole of the Northern Andes,
and at the same time one of the most threatened from a multitude
of human induced pressures. From 2006 to 2009, WWF in Peru and Colom-
bia and Fundación Natura Ecuador developed a tri-national project in the
ECR funded by the European Union that aimed to improve regional coordi-
nation, maintain the integrity of natural ecosystems and promote sustain-
able livelihoods. The project targeted actions that could contribute to re-

Guidelines for a
regional strategy 3
T
he assessment of vulnerability to climate change is important to re-
spond to future risks. In the case of the Eastern Cordillera Real (ECR)
there are serious reasons for concern (see conclusions chart of the
analysis).For this reason, and in order to help develop a regional strategy to
address at different scales the multiple threats arising from climate change
in the ECR, in this section we propose a set of guidelines derived from a
combination of exercises and workshops held under the project “A Living
Landscape.” We hope that the guidelines outlined here will form the basis
for a collegiate effort that results in regional integration around the con-
servation and sustainable development of the ecosystems of the Eastern
Cordillera Real, regarding the challenges and threats they face in relation to
the global climate change.

changes in the distribution of eco-
systems and species, increased loss
of agricultural crops), 3) the sensitiv-
ity resulting from cultural factors
and practices (extensive grazing, in-
adequate and illegal exploitation of
timber and non - timber forest prod-
ucts, industrial expansion of forest
and agricultural plantations, un-
sustainable systems of small-scale
production and the development of
mega infrastructure projects), and 4)
