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. CIAT donors generously funded the development of Accessibility Analyst, in particular, the Ecoregional Fund to Support Methodological Initiatives (managed by the International Service for National Agricultural Research); Environmental Economics and Indicators Unit of the World Bank; and the Regional Office for Latin America and the Caribbean of the United Nations Environment Programme

CIAT and its partners designed this project in 1996 to help organizations, operating on multiple political and geographical scales, plan collective action to speed up the slow progress being made toward more productive, sustainable, and environmentally healthy hillsides. The multiple goals of natural resource management and agricultural socioeconomic activities often transcend field and farm boundaries, necessitating collective analyses, negotiations, and action to solve problems. To promote "transboundary" collective action, the project uses various databases, including the Atlas of Honduras; various computer applications and procedures, including Accessibility Wizard and Spatial Water Budget Model; and computerized tools, including Intelligent Team Decision Assistant and Ecoregional Process. The project also held a review workshop and created a CD-ROM of its documents and tools.

Agricultural, environmental, and social scientists review systems research in the tropics and discuss future directions. To combat rural poverty and environmental degradation, collaborative teams of researchers have characterized the dynamics of resource use systems, helped to develop technical alternatives, and worked with farmers as partners in participatory research. Such efforts also feature the integration of germplasm research and natural resource management, use of geographic information systems tools, and development of institutional innovations. The book comprises 13 chapters developed from a 1997 workshop held at CIAT. 165 p. 16.5 x 23.5 cm.
