LA_06: Assessment of Impacts and Adaptation Measures for the Water Resources Sector due to Extreme Events under Climate Change Conditions in Central America Countries: Guatemala, Belize, Honduras, Nicaragua, El Salvador, Costa Rica and Panama. Sectors: Water resources and interacting sectors (Agriculture, tourism, disaster management) PI: Dr. Walter Fernández, UCR. Projects in Meso-America: LA__29: Integrated Assessment of Social Vulnerability and Adaptation to Climate Variability and Change Among Farmers in Mexico and Argentina Countries: 2, Mexico and Argentina, also includes Colombia, Brazil and Chile. Sectors: Agriculture and Water PI: Dr. Carlos Gay, UNAM. SIS_06. The Threat of Dengue Fever – Assessment of Impacts and Adaptation to Climate Change in Human Health in the Caribbean. Countries: Jamaica, Barbados, Trinidad and Tobago and St. Kitts. Sectors: Climate-Health and disease. PI: Drs. A. A. Chen, UWI and S. C. Rawlins, CAREC.
SIS06, Methodology include: n Retrospective study (interdisciplinary) n Statistical downscaling n Pilot Project n SRES emission scenarios
The linkage between climate and non- climate scenarios will be achieved by n Interdisciplinary teams work. n Future Global and Regional Scenarios (Tools like MAGICC & SCENGEN, PRECIS ?,…).
Climate Information used by the three projects includes n 1. Historical climatic data. –a. Local/regional data. Public domain databases. National Meteorological Services & Local stations –b. R e-analyses (NCEP) 2. Aerological DataBases: CARDS, PACS- SONET 2. Aerological DataBases: CARDS, PACS- SONET n 3. GCM outputs.
Variables required for I, A & V assessment: n Temperature (Max., Min., Mean) n Precipitation n Solar Radiation n Winds n Runoff n Also, some non-climate variables: power generation, yields, population growth, GDP, etc.
Some Critical Uncertainties in the projects are: n Spatial downscaling of climate and socio-economic scenarios. n Behaviour of Extreme Events in climate change scenarios: trends, frequency, intensity. n Baseline.
Spatial and Temporal scales include: n Spatial scale: –Local / Regional. –Global. For climate change scenarios and downscaling techniques n Temporal: daily, monthly, seasonal, annual, decadal. Baseline: 1961-1990 or at least 30 years of data of the variables described. Baseline: 1961-1990 or at least 30 years of data of the variables described.
Other projects in the region: n “Development of a regional climate model system for Central America”. Supported by NOAA-OGP. PI. Dr. Jorge A. Amador, CIGEFI-UCR, Costa Rica. n “Climate variability and its impacts on the Mexican, Central American and Caribbean region”. Supported by IAI as a CRN. PI. Dr. Victor Magaña, UNAM, México. n “When Oceans conspire: Examining the effect of concurrent SST anomalies in the Tropical Atlantic and Pacific on Caribbean Rainfall”. Supported by IAI as a PESCA project. PIs. Drs. Michael Taylor and Anthony Chen, UWI, Jamaica. n “Multi-objective study of climate variability for mitigation in the trade convergence climate complex”. Supported by IAI as a CRN. PI. M.Sc. Pilar Cornejo, ESPOL, Ecuador.
