Interpretive Summary:

Technical Abstract: The Central American Dry Corridor (CADC) consists of diverse ecosystems which mainly present ecological characteristics of tropical and subtropical dry forests. The unbalanced use of fertilizer, the loss of organic matter, erosion and inefficient water management are some of the problems affecting soils in the CADC. The sustainable management of soil and water resources is necessary to reduce vulnerability to climate variability, mitigate the impact of natural disasters and improve the productivity of rainfed agriculture. Soil information is essential for sustainable management; however, the current state of the soil data and lack of information about it limits its use in management. A regional effort has been conducted to establish a soil spatial information system (SSIS) in Guatemala, El Salvador, Honduras and Nicaragua. The main goal of the SSIS is to build databases of geo-located soil observations, as well as digital layers of spatial information related to soils and environmental data. As byproducts of the SSIS, digital soil maps were produced and evaluated by means of computational statistics and spatial modelling.
