The 33rd meeting of the Conference of the Parties (CoP-33) of the Inter-American Institute for Global Change Research (IAI) took place in Asunción, Paraguay, on May 29-30, 2025. The meeting focused on strengthening regional scientific collaboration, advancing science diplomacy, and enhancing climate resilience across the Americas. Key outcomes included the adoption of 18 decisions, the creation of an Indigenous Peoples Advisory Committee (IPAC), the approval of an updated Open Science and Open Data Policy, and the admission of three new Associate members: the World Meteorological Organization (WMO), the American Geophysical Union (AGU), and the Venezuelan Institute for Scientific Research (IVIC).

This research paper analyzes the trade-offs between agricultural production risk and ecohydrologic risk (specifically dryland salinity caused by deep drainage) in the semiarid Chaco Plains, proposing flexible cropping sequences based on soil water content to balance these risks.

This research paper evaluates and compares four precipitation datasets—CFSR, MERRA, TRMM3B42, and a 'Combined Scheme' (CoSch)—against ground observations in Bolivia, focusing on the central Andes, Altiplano, southwestern Amazonia, and Chaco across rainy and dry seasons.

The research proposes two quantitative Resprouting Capacity Indices (RCI 1 and RCI 2) to measure the post-fire recovery of seasonally dry forest species, demonstrating that these indices provide more detailed data than survival-based assessments and are influenced by species, growth form, and plant size.

The report from the Executive Directorate of the Inter-American Institute for Global Change Research (IAI) to the 20th Conference of the Parties (2012) details the outcomes of the second round of Cooperative Research Networks (CRNII) and the Human Dimensions Small Grants Program (SGP-HD). It highlights scientific findings on land-use change in the Plata Basin, the establishment of a Water Security Center of Excellence, and the launch of new NSF-funded grants (SGP-CRA and CRN3). The document also reports significant administrative challenges in Brazil, including severe IT connectivity issues and legal/tax disputes regarding the employment of Brazilian staff.
