Sudan is highly vulnerable to climate change due to its reliance on rain-fed agriculture, with projections indicating significant declines in crop yields and increased water scarcity by 2060. The document argues that while the country has established frameworks like the Environmental Protection Act of 2001 and the National Adaptation Program of Action (NAPA), effective adaptation is hindered by political instability, top-down planning, and land tenure conflicts. It recommends a comprehensive approach including land tenure reform, a national early warning system, and the integration of climate risks into all levels of national development planning.

The report finds that existing climate variability already costs Kenya up to 2% of GDP annually, with future climate change potentially adding a loss of 2.6% of GDP per year by 2030. Adaptation needs are estimated at $500 million per year for 2012, rising to $1-2 billion per year by 2030. The study also identifies significant opportunities for low-carbon growth, noting that over 80% of selected energy-related emission reduction options can be realized at a net negative cost.

The report finds that global progress toward the human development MDGs is inadequate, with Sub-Saharan Africa off track for every goal. It identifies critical bottlenecks in the supply of skilled health and education workers and a disconnect between the need for recurrent personnel funding and the technical assistance provided by donors. The document advocates for pragmatic human resource strategies, such as using paraprofessionals and contract teachers, and calls for a shift toward predictable, budget-aligned donor support and improved public sector accountability to ensure services reach the poorest populations.

The IAI CRN program has established a broad network of scientists and institutions across the Americas and globally, leveraging over US$ 20.7 million in additional funds. The initiative has supported 429 students and produced a significant volume of refereed publications between 1999 and 2003. Specific project summaries highlight research on climate variability in Mesoamerica, water quality in the Andean Amazon, ENSO risk management, biodiversity in grasslands and forests, and the impacts of cattle ranching on deforestation in Brazil, Peru, and Ecuador.

The report details the academic and research productivity of several CRN members, including student supervision, workshop organization, and a comprehensive list of publications and presentations. It highlights a significant growth in the program's scale, with the number of participating institutions increasing from 130 in July 1999 to 236 by June 2003, and the number of researchers growing from 171 to 347 in the same period. Key research areas include climate variability, the El Niño-Southern Oscillation (ENSO) and its impacts on health (specifically malaria) and hydrology, ultraviolet (UV) radiation effects on aquatic ecosystems, and dendrochronology in the Americas.

The report examines the intersection of poverty, environmental degradation, and health in the Greater Accra Metropolitan Area (GAMA). It identifies critical deficiencies in water supply, sanitation, solid waste management, and air quality, linking these to high prevalences of childhood diarrhoea and respiratory infections. The study highlights that while the wealthy have better access to amenities, the poor face severe risks from shared facilities, water vendors, and biomass cooking fuels. It concludes that integrated environmental strategies and poverty alleviation are essential for improving public health in the region.

The document details how climate change causes direct health trauma through heat, wildfires, and storms, and indirect impacts via natural and human systems. It highlights WHO projections for increased deaths from heat and diarrhoeal diseases, the expansion of vector-borne diseases like malaria and dengue, and the risk of widespread undernutrition. Additionally, it addresses the socio-economic drivers of health decline, including extreme poverty, forced migration, and increased conflict, while identifying highly vulnerable populations such as indigenous peoples and those in low-income countries.

The document warns that a 1.5°C global temperature increase will result in a 2°C rise for Namibia, potentially within the next decade. This warming is expected to cause decreased annual rainfall, more frequent heat waves, and a loss of approximately 30% of species. Health risks include increased vulnerability to heat stroke and potential disease outbreaks in new areas, although malaria may decrease due to drier conditions. To adapt, the document recommends diversifying farming, implementing rangeland management, and practicing soil and water conservation.

The document examines the intersection of climate change, population growth, and malaria in Uganda's Tororo and Kabale districts. It projects that the economic costs of malaria in these areas could more than double by 2050, driven by rising temperatures and increased population exposure. The study emphasizes the need for district-specific adaptation strategies, such as Long Lasting Insecticide Nets (LLINs) and Indoor Residential Spraying (IRS), and calls for improved climate-malaria research and cross-ministerial collaboration to maximize health co-benefits.

The LUCIA project developed a computational Agent-Based Model (MBA) to simulate malaria transmission by accounting for the interactions between mosquitoes, parasites, and humans. Validated in regions of Brazil, Ecuador, and Peru, the model demonstrates that land-use changes—such as deforestation, mining, and agricultural expansion—combined with climate factors like river flooding, increase human vulnerability to malaria. Findings indicate that risk is higher for isolated homes on the outskirts of populations compared to central areas. The research suggests that managing larval breeding sites within 200 meters of populations can eliminate disease transmission, and notes that Ecuador has already modified its mining policies as a result.

The document outlines multiple IAI-funded research projects focusing on environmental and social vulnerabilities in the Americas. Key initiatives include the study of nitrogen cycling and wastewater treatment in Latin America, the conservation of tropical dry forests, the provision of climate services for agriculture in southeastern South America, and the assessment of freshwater ecosystem risks. Other projects examine the link between land use and malaria in the Amazon, water security in arid regions, the role of phytoplankton in carbon sequestration, the impact of transcontinental highways on zoonotic disease risk in Peru, and urban hydrological vulnerability in Mexico City.

The CRN program established multidisciplinary international research networks to study climate variability, ecosystem functioning, and human dimensions of global change in the Americas. Key achievements include the development of high-resolution climate reconstructions using tree rings, the identification of critical soil degradation thresholds in semiarid regions, and the creation of disaster risk databases for ENSO events. The program emphasized capacity building, supporting over 600 students and producing hundreds of peer-reviewed publications, while fostering South-South and North-South scientific collaborations.

The report identifies 37 unique software tools for climate-sensitive infectious disease modelling, finding a heavy bias toward vector-borne diseases, particularly malaria. It highlights significant gaps in operationalization, accessibility, and geographic representation, noting that most tools are developed by North American and European institutions despite being intended for use in the Global South. Expert interviews reveal critical barriers to implementation, including poor data sharing between climate and health sectors, lack of political mandates, and a mismatch between complex model outputs and the needs of public health decision-makers.

The report investigates the intersection of poverty and environmental degradation in the Greater Accra Metropolitan Area (GAMA), Ghana. It finds that low-income households suffer from severe deficiencies in water access, sanitation, and waste management, which correlate strongly with high prevalences of childhood diarrhoea and acute respiratory infections. The study highlights that while the city has some advanced infrastructure, extreme crowding and unreliable supply systems negate these advantages for the poor. It concludes that an integrated environmental-health strategy, leveraging both government action and local community organisations, is necessary to improve urban welfare.

The report finds that Rwanda faces significant economic costs from existing climate variability and future climate change, particularly in health, agriculture, and water sectors. It estimates that future climate change could cost Rwanda nearly 1% of its GDP annually by 2030, excluding extreme events. Adaptation costs are projected to range from $50 million to $600 million per year by 2030, depending on whether development-related needs are included. The study also identifies a low-carbon growth pathway as being in Rwanda's self-interest to avoid 'lock-in' to high-emission infrastructure and to access carbon financing.

The document introduces a data set providing 14 city-relevant climate hazard indicators for 996 large cities, based on NEX-GDDP-CMIP6 downscaled climate simulations. It compares a 1994-2014 historical baseline against three warming scenarios (1.5°C, 2.0°C, and 3.0°C) to assist city decision-makers in strategic planning and risk management. Key findings indicate that at 3.0°C of warming, cities will experience heatwaves that are 28% longer and 25% more frequent on average than at 1.5°C, alongside increased energy demand for cooling and higher transmission risks for arboviruses.
