This briefing, prepared by the permanent representative of Paraguay for the thirty-third meeting of the Conference of the Parties to the Inter-American Institute for Global Change Research (IAI), proposes that the World Meteorological Organization (WMO) be invited to become an Associate of the Institute. The document outlines the WMO's regional and global roles in climate cooperation and details its existing collaborative activities with the IAI since 2022.

This research paper examines the hydrological impacts of tree plantations in South America, noting that while they expand by 5,000 km²/year, their effect on water yields and soil salinity varies significantly based on climate, topography, and the type of native vegetation replaced.

This research paper analyzes the impact of drought and wet events in the Sauce Grande lagoon watershed region of Buenos Aires, Argentina, between 1971 and 2010 using the Palmer Drought Severity Index.

The Nature-Based Infrastructure (NBI) Global Resource Centre conducted a cost-benefit analysis of ecosystem-based adaptation in Costa Rica's Reventazón River basin to stabilize hydrology and secure water and energy supplies.

This fact sheet describes the hydrology of the lower Winnipeg River basin (LWRB), focusing on river discharge, water levels, and the role of hydroelectric generating stations. It provides historical discharge data, climate projections for the 2050s, and discusses the river's contribution to Lake Winnipeg's water volume and nutrient loading.

This research paper assesses the combined impacts of climate change and mining activities on streamflow and heavy metal loading in the Chindwin River, Myanmar, using hydrological and geochemical modelling.

This research paper describes an integrated hydrology and water operations simulation model developed using the Water Evaluation and Planning (WEAP) platform to assess the impacts of climate change on water supply reliability in the Tuolumne and Merced River Basins of California.

This research paper assesses the impact of climate change on the Gilgel Abay River in Ethiopia's Upper Blue Nile Basin using the Statistical Downscaling Tool (SDSM) and the Soil and Water Assessment Tool (SWAT). The study projects fluctuating precipitation and flow volumes between 2010 and 2100, ultimately predicting an overall annual increase in flow volume that could benefit local irrigation and dam projects.

The 2011 Report on Science Program by the Inter-American Institute for Global Change Research (IAI) details the achievements of four scientific programs between May 2010 and April 2011. These include the Second Collaborative Research Network (CRNII), the Small Grants Program for the Human Dimensions (SGP-HD), and a project on land use and biofuels in the La Plata Basin. The report emphasizes the integration of social and economic research into natural science to bridge the science-policy divide, highlighting impacts on urban pollution management, forest conservation, and agricultural risk reduction across the Americas.

The document contains the minutes of the Seventeenth IAI Conference of the Parties (CoP), held on June 9-10, 2010, in Brasilia, Brazil. The meeting focused on the Inter-American Institute for Global Change Research's (IAI) financial status, the approval of its 2010-2011 core budget and annual program, and the election of members to its Scientific Advisory Committee (SAC) and Executive Council (EC). It also details national reports on climate change mitigation and adaptation from member countries and discusses the development of a new strategic plan and potential involvement in REDD+ initiatives.

This case study describes the development of an integrated modelling system using the Water Evaluation and Planning (WEAP) system to analyze the hydrologic role of glaciers in the Rio Santa watershed of Peru, intended as a decision support tool for climate change adaptation.

This report summarizes the development of methodological tools designed to assess how climate change affects surface hydrology in the Peruvian Andes, intended as guidance for decision-makers in Peru and other nations.

The authors introduce MILLENNIA, a peat age-cohort model designed to address shortcomings in global soil models regarding the representation of long-term soil organic carbon (SOC) accumulation and dynamic hydrological processes, specifically water table depth (WTD). The model's predictions for SOC accumulation and peat ages were validated against observations from a UK peatland site.

This fact sheet describes a research project focused on the Rio de la Plata Basin, examining the drivers and consequences of land use change, specifically the trade-offs between food and biofuel production and the maintenance of ecosystem services.

This document is a budget request from the Inter-American Institute for Global Change Research (IAI) for the 2008/2009 fiscal year, including preliminary projections for 2009-2011. It details the funding required for the IAI Directorate's operations, scientific programs, capacity building, and administrative costs, while outlining the expected contributions from member countries.

The Report of the CRN-I Program details the outcomes of the Inter-American Institute for Global Change Research's (IAI) Collaborative Research Network (CRN) program, which operated from 1999 to 2003. The program invested approximately US$10 million across 14 grants to foster multidisciplinary, international research networks focused on global change phenomena in the Americas, with a strong emphasis on scientific capacity building and policy relevance.

This document is an affidavit by Karen King, a professional hydrologist and soil scientist, submitted to the High Court of South Africa Gauteng Division. King confirms her professional qualifications and her role in co-authoring a review of the proposed Yzermyn Colliery in Mpumalanga.

The 2011 IAI Science Report details the achievements of four scientific programs between May 2010 and April 2011, focusing on the Second Collaborative Research Network (CRNII), the Small Grants Program for the Human Dimensions (SGP-HD), and an IDRC-funded project on the La Plata Basin. The report emphasizes the integration of natural and social sciences to inform policy and the development of scientific capacity across the Americas, resulting in 343 joint scientific publications by April 2011.

This report examines the relationship between land use and hydrology in the La Plata Basin. Key findings include the identification of optimal groundwater depths for corn, soybean, and wheat in the Pampas, and evidence that replacing pastures with annual crops increases flooding risks. In the Chaco-Espinal region, agricultural expansion has triggered groundwater salinization and the emergence of new streams. In Paraguay, deforestation of the Atlantic Forest increased water yield from 40% to 70% of rainfall. The report also argues that bioelectricity from fire-prone dry forests is a more carbon-efficient energy source than soybean biodiesel, which carries a significant carbon debt from land-use change.

This SEI fact sheet examines the impact of land-use change, deforestation, and decentralized water infrastructure on the hydrology of the Chiquitano dry forest in Bolivia, specifically within the Santa Cruz Department. It highlights the proliferation of 'atajados' (artificial storage ponds) and groundwater wells driven by agricultural expansion, noting that these unregulated diversions are not currently represented in regional hydrologic models and may threaten downstream ecosystems and water availability.
