The Andean snowpack is the primary water source for households, agriculture, industry, hydropower, and ecosystems in semi-arid central Chile and central-western Argentina. Analysis of regional composite data shows that winter snowpack and river streamflow are closely related and influenced by large-scale Pacific surface temperature changes. High snowpack and streamflow coincide with warm El Niño events, while most extreme dry years occur during cold La Niña events. Additionally, shifts in the Pacific Decadal Oscillation (PDO) in the mid-1940s and 1976-77 correspond to a 27% decrease and 28% increase in mean annual river discharges, respectively, suggesting the PDO causes low-frequency hydrologic variations. While lower PDO values in the late 1990s were not matched by streamflow records—possibly due to melting glaciers—the interplay between ENSO and PDO is highlighted as critical for improving water scarcity forecasts under a changing climate.

The document examines the relationship between Pacific Ocean temperature patterns and water availability in the semi-arid regions of central Chile and west-central Argentina. It identifies that winter snowpack is the primary water source for these areas and is strongly influenced by ENSO and PDO cycles. Specifically, El Niño events correlate with high snow and flow, while La Niña events generally correlate with dry years. The document also notes that shifts in the PDO in the 1940s and 1970s coincided with significant changes in average river flows, suggesting that multidecadal PDO behavior drives low-frequency hydrological variations in the region.

The report argues that while biomass is essential for a low-carbon economy, it is a limited resource constrained by land, water, and the need for ecosystem functioning. Through four scenarios, the authors demonstrate that a 'Sustainability Transition'—combining aggressive climate policy with focused agricultural productivity improvements—is the most viable path to reducing emissions without excessively increasing the agricultural footprint. The analysis highlights that future yield gains must move beyond the 'Green Revolution' strategy of increasing harvest index (shifting biomass to grain) toward increasing total photosynthetic efficiency to provide enough raw material for both food and industrial bio-materials.

The author examines how 'paralysing defeatism' and 'complacency' prevent the implementation of feasible mitigation and adaptation measures. He argues that personal responsibility for climate change is grounded in both prudence and ethics, particularly for those in the Global North who have benefited from industrial development. To counter inaction, the author suggests using local, concrete evidence of climate change and fostering solidarity with vulnerable populations to shift the cultural beliefs and habits that obstruct action.

The document outlines two primary categories of geoengineering: carbon geoengineering (CO2 removal) and solar geoengineering (solar radiation management). It details a four-stage research progression from theory to large-scale testing and highlights critical ethical, political, and social risks, including moral hazard and equity for vulnerable populations. The authors argue for the urgent development of a transparent international governance framework to manage these technologies responsibly.

The provided text is a publication list for a project titled 'Landuse change, biofuels and rural development in the La Plata Basin'. It enumerates various academic papers, theses, and reports published between 2006 and 2011. The listed works focus on ecohydrology, satellite monitoring of land use, the environmental and social impacts of biofuels in South America, and the ecological footprint of agricultural expansion, particularly in Argentina, Brazil, and Uruguay.

The report advocates for the adoption of sustainable public procurement (SPP) during post-disaster and post-conflict reconstruction. It highlights that the high volume of public spending during these periods—often ranging from 2% to 15% of annual GDP for recovery—can be used to signal long-term demand for green goods and services, stimulate private sector innovation, and build domestic capacity for sustainable production. The author provides evidence that integrating sustainability into infrastructure rebuilding, such as mangrove conservation in Vietnam or flood-resistant works in China, significantly reduces future disaster losses and improves resilience. However, the report notes that implementation is often hindered by a lack of dedicated SPP laws and political instability in lower-income economies.

The research evaluates the economic impact of forest area changes from 2000 to 2050, focusing on provisioning, regulating, and cultural services. Using a combination of market data, meta-analysis, and value transfer, the study finds that while managed forests may increase provisioning revenues, the loss of natural forests—particularly in tropical and boreal biomes—leads to significant welfare losses, primarily driven by the loss of carbon sequestration capacity. Brazil is projected to suffer the highest economic loss, potentially reaching 6% of its 2050 GDP.

The document examines the vulnerability of the European power sector to climate change, focusing on the interdependence between water supply and electricity generation. It argues that rising temperatures and water scarcity can force power plants, particularly nuclear facilities, to reduce production, which in turn disrupts the European electricity exchange system. Using a theoretical model and scenarios based on IPCC projections, the authors demonstrate that countries heavily dependent on electricity imports, such as Italy and the Netherlands, are particularly vulnerable to production constraints in major exporting nations like France.

The document asserts that tree plantations are uniform agricultural systems that cause biodiversity loss, community displacement, and hydrological alteration. It criticizes the use of these plantations as carbon sinks under the Kyoto Protocol, arguing that such schemes provide a 'fictional solution' to climate change while benefiting transnational corporations. The paper further denounces international organizations like the FAO for legitimizing plantations by classifying them as forests.

The project investigates long-term hydrological changes in the American cordillera, utilizing tree-ring records and streamflow data to analyze drought patterns and climate regime shifts. Initial findings highlight a severe 14th-century drought in the high Andes with significant social consequences, a declining streamflow trend in Chile linked to the Pacific Decadal Oscillation, and an increasing drought risk in the southern Andes between 1920 and 2002 that threatens agriculture and hydroelectric power.

The report assesses the environmental footprint of Chinese copper cathode production, which relies heavily on imports. Using a 'cradle-to-gate' LCA, it finds that mining and mineral extraction are the primary drivers of environmental impact, accounting for over 70% of the total for primary production. While Chinese primary production has lower impacts than the global average and regions like Latin America and Indonesia, it remains higher than European production due to lower ore grades and a fossil-fuel-heavy electricity mix. The study recommends improving mining technologies, enhancing the collection and recycling of secondary copper, and phasing out obsolete smelting technologies.

The IAI is seeking to fill two vacancies on its Science Advisory Council in 2010, replacing Rana Fine and Maria Carmen Lemos. The nominations will target four priority areas: Climate Science (specifically climate modeling), Ecosystems and climate (specifically biodiversity), Policy and Human Dimensions of global change (including vulnerability assessment, mitigation, adaptation, and science-policy interaction), and Integration and modeling (focusing on resilience and social-ecological systems modeling). Candidates are evaluated based on basic criteria of scientific excellence, geopolitical balance across the Americas and the Caribbean, and gender balance, as well as second-tier considerations including interdisciplinary research ability, representation of science in the Americas, and the ability to bridge the science-policy divide.

A global coalition of civil society organizations, including Friends of the Earth International, issued a statement on December 7, 2009, condemning the Danish government's conduct as President of the UNFCCC Conference of Parties. The groups argue that the Danish Prime Minister undermined democratic UN processes by convening exclusive groups of countries and drafting "Copenhagen Accords" before the meeting began, effectively excluding most nations and ignoring the demands of developing countries. The statement asserts that these actions shift the burden of climate change from developed to developing nations and threaten the potential for a fair and effective agreement in Copenhagen.

The analysis finds that retrofitting U.S. Class 8 trucks with DPFs provides significant near-term climate benefits by reducing black carbon, a potent warming agent. Using a 'best estimate' 20-year global warming potential (GWP20) of 2,200, the study calculates a net benefit of approximately 2,080 gCO2e per gallon of diesel fuel, even when assuming a conservative 2% fuel penalty. The report concludes that such retrofits are climate-beneficial as long as the fuel penalty remains below 22% (GWP20) or 7% (GWP100). A hypothetical rebuild rule retrofitting nearly one million trucks between 2012 and 2030 would result in a total CO2e reduction of 96 million metric tons (GWP20), equivalent to eliminating the annual emissions of 21 million cars.

The paper assesses how voluntary sustainability standards (VSS) affect global value chains in coffee, fisheries, and forestry. It finds that while VSS can create economic rents through improved organizational capacity and better relational ties, they often reinforce existing power imbalances. Market growth is largely driven by large retailers in North America and Europe, and certification costs frequently act as a barrier to the most marginalized producers in developing regions.

The document analyzes the landscape of emissions trading schemes (ETS) in North America, noting that while regional initiatives like the Western Climate Initiative (WCI) and Regional Greenhouse Gas Initiative (RGGI) are advanced, national efforts in the US and Canada face coordination challenges. It argues that linking is logical due to economic ties, but current designs—particularly Canada's intensity-based targets—create barriers to bilateral links with absolute-cap schemes. The author concludes that a US federal scheme would likely preempt most state schemes, while Canada may use equivalency agreements to allow provincial schemes to persist.

The document argues that corruption in public procurement is a systemic issue in Africa, costing the continent approximately $148 billion annually and serving as a primary driver of poverty. It identifies a cycle where 'grand corruption' by elites leads to poverty, which in turn fuels 'petty corruption' among underpaid public servants. The author advocates for a comprehensive approach combining political will, robust legal frameworks, transparency, and the involvement of non-state actors to reduce corruption to marginal levels.

The document argues that corruption in public procurement is a primary driver of poverty in Africa, potentially costing the continent $148 billion annually. It identifies a cycle where 'grande corruption' (large-scale corruption) by elites leads to national poverty, which in turn fuels 'petite corruption' (small-scale corruption) among underpaid officials. The author advocates for a comprehensive approach combining strong anti-corruption legislation, political will from top leadership, transparency in bidding processes, and the involvement of non-governmental actors to reduce corruption to marginal levels.

The document details the biological and physical shifts resulting from global warming, noting that minimum temperatures are rising faster than maximum temperatures. This trend has led to earlier ice break-up, snow melt, and the advancement of biological events such as bird nesting and plant flowering, particularly in Europe and North America. These shifts create risks of ecological desynchronization, such as polar bears in Hudson Bay having less time to hunt on sea ice.
