Proceedings of a workshop held in Embilipitiya, Sri Lanka, 29th March 2001. Presents preliminary findings on malaria patterns and possible risk factors and describes the progress of IWMI research towards developing a risk map for Sri Lanka. It also contains presentations by Regional Malaria Officers, and other officials involved in malaria control, on areas of high malaria risk within their districts.

OBJETIVO: Identificar zonas geográficas de América Latina y el Caribe para la biofortificación de cultivos básicos como frijol, maíz, arroz, yuca y batata, contribuyendo así a reducir las deficiencias nutricionales en la Región.

CIAT programmed this simple and flexible GIS tool to automate the creation of accessibility surfaces. Previously, these surfaces were laboriously created, step-by-step, using ArcINFO software from the Environmental Systems Research Institute (ESRI). You can install the Accessibility Analyst if you have the ESRI ArcView 3 software and its ArcView Spatial Analyst. From this page, you can download the extension and documentation, see case studies of the extension at work, and follow up links with other people working in the same field.

The world is facing severe and growing challenges in maintaining water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop.

The importance of poverty reduction to the world development agenda has motivated greater interest in the geographic dimensions of poverty and food security. This special issue of Food Policy includes examples of poverty and food security mapping used to support policy development in agricultural and rural areas. The volume includes eight country case studies and one cross-country comparison that illustrate advances in our capacity to assess welfare over large areas and at detailed spatial resolutions.

Groundwater development potential in northern Ghana (108 671 km2) has been assessed by combining spatial layers for five critical factors?recharge rate, regolith thickness, transmissivity, borehole success rate and static water level?through a multi-criteria analysis approach to rank development potential from the viewpoint of groundwater availability and accessibility at a resolution of 1 km2.
