This research paper introduces a multiple criteria spectral mixture analysis (MCSMA) method using shortwave infrared (SWIR) data from HyMap imagery to map the successional stages of tropical dry forests (TDFs) in Costa Rica, demonstrating improved accuracy over existing methods.

The IAI report (July 2016 - May 2017) outlines progress in transdisciplinary climate research and science-policy integration in the Americas. Key achievements include the evaluation of the TISG seed grant program, the management of 17 CRN3 research networks, the launch of a climate impact MOOC with over 6,500 participants, and the establishment of a Science-Policy Liaison Office in Buenos Aires to measure scientific impact on regional governance.

This report details several research initiatives supported by the Inter-American Institute for Global Change Research (IAI) across the Americas. These projects focus on the intersection of environmental science and public policy, addressing nitrogen cycling, tropical dry forest conservation, climate services for agriculture, freshwater ecosystem risks, malaria transmission in the Amazon, water security in arid regions, oceanic carbon sequestration, the impact of highways on zoonotic diseases, and urban hydrological vulnerability.

This document is a collection of project briefs from the Inter-American Institute for Global Change Research (IAI) detailing various scientific research initiatives across the Americas. The projects focus on environmental sustainability, climate change adaptation, and the intersection of ecological health and human well-being, covering topics such as the nitrogen cycle, tropical dry forests, climate services, malaria transmission in the Amazon, freshwater ecosystem risks, water security in arid zones, ocean dynamics, the impact of road construction in rainforests, phytoplankton services, and urban hydrological risks.

This working paper analyzes transformative climate adaptation in Bhutan, Ethiopia, and Costa Rica, focusing on water scarcity, landscape degradation, and agricultural shifts. It identifies that while some communities are initiating autonomous system shifts, they lack the technical and financial support needed for scalability. Key recommendations include investing in automated monitoring, mobilizing community change agents, and providing targeted financial credit for farmers transitioning to climate-resilient livelihoods.
