It provides a list of technical resources and experts for further reporting.

The 'Resilient Puna' project is a 6-year initiative in the Southern High Andes of Peru (SHAP) designed to restore and conserve 23,914 hectares of Puna ecosystems (peatlands, wetlands, and grasslands). The project focuses on enhancing the resilience of 60,715 direct beneficiaries, primarily Quechua Indigenous Peoples, by integrating ancestral knowledge with modern science to implement EbA measures and develop Climate Resilient Value Chains (CRVC). A central feature is the 'Puna Facility,' a financial mechanism managed by Profonanpe that provides non-repayable and repayable grants to local initiatives. The project also aims to mainstream EbA into national and regional governance, improve water security for over 2 million indirect beneficiaries, and achieve a mitigation co-benefit of 407,657 tCO2eq.

The Plan Director de la Cuenca Alta del Rio La Paz provides a comprehensive diagnostic and strategic roadmap for managing water resources in a 1,725 km² area. It identifies critical vulnerabilities, including severe water pollution in urban rivers, glacier retreat, and inadequate sanitation in rural areas. The plan proposes 11 strategic lines (LE) focusing on climate resilience, water governance, technological innovation in irrigation, and the construction of wastewater treatment plants (PTAR), with a total estimated investment of 1,555,183,480 BOB.

The document details how East Africa has experienced warming exceeding the global average, leading to increased drought frequency, glacier loss, and significant economic losses. Future projections indicate severe risks to human health, food security, and biodiversity, particularly if warming exceeds 1.5°C. It emphasizes the need for transformative adaptation, increased climate finance, and improved climate services to build regional resilience.

The Hindu Kush Himalayas, known as the 'Third Pole', are experiencing rapid glacier retreat due to climate change, leading to an increase in the number and volume of glacial lakes. This has heightened the risk of glacial lake outburst floods (GLOFs), which often present transboundary threats, as seen in the 2016 Bhote Koshi River flood where a lake breach in Tibet caused $70 million in damages in Nepal. Despite the high risk, early-warning systems are inadequate and cross-border cooperation remains limited, although initiatives like the Hindu Kush Himalaya Glaciers and Mountain Economy Network and the Koshi Basin Initiative aim to improve regional resilience.

The document describes the use of a WEAP model and a 36-year remote sensing dataset (1984–2020) to analyze bofedales wetlands in Bolivia's Katari watershed. It identifies that while glacier retreat in the Cordillera Real is evident, bofedales currently show a greening trend potentially due to increased meltwater and higher temperatures, though long-term decline is expected as aquifer recharge drops. The study also notes that human activities, including overgrazing and mining-related groundwater extraction, are deteriorating wetland health.

The project focuses on the Katari watershed in Bolivia, where high-altitude wetlands known as "bofedales" are critical for regulating water balance and supplying drinking water to La Paz and El Alto. These ecosystems are currently deteriorating due to climate change, glacier retreat, rapid urbanization, overgrazing, and mining-related groundwater extraction. To address this, the Stockholm Environment Institute (SEI) is using multi-temporal remote sensing data from 1984-2020 and the WEAP modelling platform to establish eco-hydrological baselines and evaluate potential conflicts between urban water demands and the preservation of these wetlands.

The document outlines the accelerating degradation of the Earth's cryosphere and oceans due to climate change. It details the rapid loss of ice sheets in Greenland and Antarctica, the thawing of permafrost, and the warming, acidification, and deoxygenation of the global oceans. These changes drive sea level rise, threaten biodiversity, and disrupt essential services like freshwater supply from mountain glaciers and food security from fisheries. The briefing emphasizes that while some damage is irreversible, cutting emissions can reduce risks and facilitate adaptation for vulnerable coastal and indigenous populations.

The document describes a meeting intended to update OAS Member States on progress in integrated water resources management (IWRM) and address emerging challenges in the Americas, such as rapid urbanization, climate change, and transboundary water conflicts. It emphasizes the role of science in reducing environmental uncertainties and proposes a cooperation-based approach to manage shared water basins, which account for approximately 60% of freshwater resources in the Americas. The session aims to identify new strategic alliances, strengthen public policies through knowledge transfer, and promote a rights-based approach to water and sanitation.

The document outlines the impacts of human-induced climate change on the oceans and cryosphere, specifically focusing on the vulnerabilities of South Asia. It details the degradation of coral reefs, rising sea levels affecting coastal megacities like Mumbai, and the melting of glaciers in high mountain Asia. The report emphasizes that while some changes are inevitable, urgent greenhouse gas mitigation and early investment in adaptation—such as nature-based 'blue carbon' solutions and integrated governance—can significantly reduce future risks and costs.

The Mendoza wine region, a primary producer of Malbec, faces a divide between large, efficient growers and smallholders who struggle with quality standards and economic stability. Climate change is threatening the region's 'oasis' by reducing snow precipitation and glacier area, which provide 70% to 80% of summer water. Current water governance, based on the 1884 Ley de Aguas de Mendoza, is deemed insufficient for these new conditions, leading to suggestions that the region adopt regional groundwater management models similar to California's.

The report details the ecological and physical vulnerability of the Central Tian Shan in the Kyrgyz Republic. It finds a general trend of glacier retreat and shrinking lakes, which threatens the region's role as the 'water tower of Central Asia' and impacts hydropower security. Biodiversity is at risk, particularly the endangered snow leopard, due to habitat shifts and prey instability, although some species have expanded their range. Future scenarios project significant temperature increases and a long-term decrease in surface runoff by 2100. The document advocates for the expansion of protected areas and the implementation of climate-smart livelihoods, such as yak breeding and ecotourism, to build community and ecosystem resilience.

The document outlines twelve key signs of climate change, including rising global, ocean, and soil temperatures, increasing ocean acidity, and rising sea levels. It attributes these phenomena to the buildup of heat-trapping gases caused by the burning of fossil fuels and the destruction of tropical forests. The text highlights specific regional impacts, such as the rapid warming of the Gulf of Maine and the thawing of permafrost in the Arctic, and notes the resulting increase in extreme weather events and shifts in species ranges.

The report analyzes Canada's comprehensive wealth—comprising natural, human, social, and produced capital—finding that while Canada remains wealthy, its wealth growth (0.19% annually) has lagged significantly behind consumption growth (1.36% annually) between 1980 and 2013. The study highlights a 25% decline in the market value of natural capital and a lack of growth in human capital, suggesting that Canada's development model relies heavily on the depletion of natural resources and a concentrated produced capital base dominated by housing and oil and gas.

The report analyzes India's high climate sensitivity, driven by its geography and agrarian economy. It details the transition from stand-alone sectoral actions to integrated development planning, centered on the National Action Plan on Climate Change (NAPCC). While progress is noted in water and agriculture, the document identifies critical gaps in adaptation for the northeast, Indian Ocean islands, the Sundarbans, and regarding gender and health. It also highlights a significant imbalance in international climate finance, which heavily favors mitigation over adaptation.

The paper argues that ecological, financial, and political systems are under increasing pressure, creating a need to integrate 'hard' security (state-centric) with 'human' security (individual and ecosystem well-being). It identifies commonalities between these fields—such as uncertainty, irreversibilities, and multi-stakeholder complexity—and proposes a three-step methodology: context analysis, participatory scenario building, and options appraisal. Case studies demonstrate how water scarcity in the Nile and Euphrates-Tigris basins, climate-driven geophysical changes in the Arctic, and energy-water dependencies in Central Asia create security risks that require integrated governance and investment strategies.

The study finds that current climate variability already costs Nepal 1.5–2% of its annual GDP, with future climate change projected to add another 2–3% of current GDP per year by mid-century. The most significant drivers of these costs are water-induced disasters, particularly floods. Sectoral analysis indicates that while agriculture faces net losses of approximately 0.8% of current GDP per year by the 2070s, the hydroelectricity sector faces high uncertainty, with projections ranging from increased investment costs of US$2.6 billion due to decreased dry season flows to potential savings of US$170 million if flows increase. To address these risks, the study recommends an iterative adaptation pathway, estimating a need for US$2.4 billion in additional investment by 2030 to mainstream resilience.

The study finds that current climate variability already costs Nepal 1.5–2% of its annual GDP, with future climate change projected to add another 2–3% of current GDP per year by mid-century. Key risks include significant agricultural losses in the Terai region, highly uncertain impacts on hydroelectricity investment costs depending on river flow projections, and a 20–100% increase in the intensity and frequency of high river flows. To address these, the report recommends an iterative adaptation pathway, estimating a need for US$2.4 billion in additional investment by 2030 to mainstream resilience.

The report examines the vulnerability of Peru's agricultural sector to climate variability and change, focusing on the Junín and Piura regions. It identifies key threats such as El Niño/Southern Oscillation (ENSO), droughts, floods, and frosts, and analyzes their impacts on priority crops like maize, potatoes, and mangoes. The document evaluates Peru's institutional capacity for risk management, noting a disconnect between disaster risk reduction and climate change adaptation frameworks. It recommends improving agricultural practices, water management, and data collection, while calling for a comprehensive national program to integrate climate risk management into development planning.

Analysis of Polylepis tarapacana tree rings in the Bolivian Altiplano reveals a severe, prolonged drought starting in 1316 that coincided with the abandonment of vulnerable settlements in favor of fortified Pukaras, suggesting environmental drivers for social conflict. The document warns that contemporary glacier retreat and increased water demand from mining, agriculture, and population growth may lead to similar water scarcity and political-economic conflicts in the 21st century.
