El objetivo de la presente investigación fue analizar la correspondencia entre los resultados de una evaluación de tierras con la distribución real de los cultivos. Para ello la aptitud biofísica de las tierras se comparó con diferentes tipologías de frecuencia de ocurrencia de los cultivos y rotaciones derivadas de mapas de cultivos multitemporales. La investigación fue llevada a cabo en el distrito de riego de Flumen (33.000 ha), localizado en el valle del Ebro (NE España).

This booklet was prepared after the December 2004 tsunami caused serious damage to agricultural land, soils and vegetation along the coastal areas of Aceh, Indonesia. The booklet is a guideline for the district government of Aceh Barat for spatial lay-outing of tree crops suitable for its coastal areas. Tree crop options considered in this booklet are based mainly on biophysical characteristics of land. The information is based on soil characteristics and climate data related to growth requirements of crops being evaluated.

This publication seeks to assist government and institutional policy-planners and decision-makers in identifying places where energy crops could be grown and in understanding the geographic (agro-ecological

and economic) context of bioenergy supplies, at country and regional levels. It will not only increase awareness about the environmental challenges

related to the production systems of bioenergy crops, but will also contribute to the development of new production practices and technologies for sustainable agricultural intensification and diversification

The purpose of this evaluation is to determine the land suitability of the Wadi Mawr area for the cultivation of (spate) irrigated sorghum under improved traditional management, and to determine the yield response to additional water gifts on various soil types. The evaluation was carried out for the alluvial plain, i.e.

En el presente nmero de Unasylva se analiza la situacin forestal en las zonas urbanas y se estudia su aporte potencial a la elevacin de los niveles de vida de los habitantes en distintos escenarios urbanos.

Issues relating to land and land reform have been moving up the agenda of rural poverty and food security in recent years with the increasing acceptance that the prerequisites for broad-based and equitable development include the essential need for people to have access to land and other natural resources. Access needs to be on an equitable basis allowing the poor and the disadvantaged, including women, to secure the assets needed for them and their families to generate sustainable livelihoods.

This bulletin gives an overview of the ninth session of the working party on Soil Classification and Survey of the European Commission on Agriculture that took place in Ghent, Belgium, in september 1973. It presents the papers, discussions and recommendations developed during the meeting. A methodology of land evaluation is being developed in FAO and will be used for the interpretation of the FAO/UNESCO Soil Map of the World with a view to making a global evaluation of the land resources available for agricultural development.
