Improved Mapping and Spatial Analysis of Food Security and Poverty in Ecuador

Almost one fifth of Ecuador's inhabitants are undernourished (FAO, 1999 ) and over a quarter of children under 5 years of age are affected by chronic malnutrition (Larrea et al, 2001 ). The need for national level assessments of food insecurity is therefore very high. This project will identify the lack of access to food within Ecuador and test hypotheses regarding the causes of food insecurity in Ecuador. This will be achieved by identifying how access to food varies spatially, how access to food varies temporally, and crucially, how the factors that contribute to food insecurity change over space and time. This project aims to benefit many different institutions in both targeting their resources and their research, specifically the capacity of the Ecuadorian government to design policy or development interventions necessary to improve food security.

Mapping of the Population of Latin America and the Caribbean

Land Use was linked to a World Resources Institute (WRI) and United Nations Program for Nature (PNUMA) project to create a database of the population of Latin America and the Caribbean. This population surface can be visualized in "raster" maps (digital information), which will be used in programs designed according to GIS standards.

The database information was obtained from more than 10 000 administrative units of the Latin American region. The census data was combined with the historic rates of population growth, and this combination was then used to project the level of the region's population in the years 1960, 1970, 1980, and 1990. The results of the population projection were transferred to a socioeconomic map, and they will be published on the Web server; in this way, the spatial data will be available for decision takers.

Mapping Food Security and Poverty through the Consortium for Spatial Information (CSI)

Poverty alleviation is central to the mission of the CGIAR and other development organizations. Yet knowledge about where poverty and food insecurity exists, and what are their modifiable drivers, is still deficient. This is partially because of a historic dearth of appropriate information. But, as the volume of data increased, it related more to our inability to access it, analyze it, and communicate the results to people who need them. Out of this was created the Consortium for Spatial Information (CSI), a network of nine CG Centers (subsequently expanded to 12 Centers), and, from the CSI, the joint CSI-Food and Agriculture Organization (FAO)-United Nations Environment Programme (UNEP) poverty mapping project. This year saw the confluence of parallel developments in three fields: GIS software, building of data-sharing capacity, and spatial analytical methodology that has enabled a significant step towards the goal of a global capacity to map poverty and its causes at national scale. These development were:

  1. Introduction of ArcIMS software, which provides real-time, dynamic Web-based mapping so that data from multiple sources can be analyzed over the Internet.
  2. Geospatial Applications to Support Sustainable International Agriculture (GASSIA) technical training workshop (with USGS) on intellectual property rights (IPR) and spatial data infrastructure requirements to enable Centers to interact with clearinghouses.
  3. Training in spatial analytical methods, and application to national scale poverty mapping in nine country case studies, funded through the CSI-FAO-UNEP.

Poverty Mapping in Honduras

Poverty mapping in Honduras represents an advance in the analysis of causality factors. This work is a significant step towards harmonizing the perceptions of poverty from the "top" (international development organizations) and "bottom" (local), by providing a methodology for extrapolating locally derived indicators up to country-level.
Some indicators of poverty in Honduras were obtained with the use of a database. They were based on local perception of census data at village level. These indicators were then compared with the results of research in the field.
