En colaboración cone el PNUMA, la FAO ha desarrollado un marco mejorado de planificación para el desarrollo y el manejo de los recursos de la tierra que enfrenta los problemas reconocidos durante la Conferencia de las Naciones Unidas sobre el Ambiente y el Desarrollo, en 1992, en Río de Janeiro, Brasil. Este documento es el último de una serie de tres publicaciones, el cual introduce estos nuevos conceptos y propone un enfoque de planificación integrada para el manejo sostenible de los recursos de la tierra basado en una asociación interactiva entre los gobiernos y la población.

Using detailed household-farm level data from Malawi, we measure real farm total factor productivity (TFP) controlling for a wide array of factor inputs, land quality, and transitory shocks. We nd that factor inputs are roughly evenly spread among farmers: operated land size and capital are essentially unrelated to farm TFP implying a strong negative eect on aggregate agricultural productivity. A reallocation of factors to their ecient use among existing farmers would increase agricultural productivity by a factor of 3.6-fold.

Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the two-week Workshop.

The Global Soil Partnership (GSP) is a major international initiative with a vision ‘to improve global governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food secure world, as well as sustain other essential ecosystem services’. The Regional Soil Partnerships are to assist the GSP to move into concrete field action at regional, national and local levels through ‘Implementation Plans’.

The objective of this Soils Bulletin is to promote the use of locally available organic materials to increase soil organic matter content for improvement of soil fertility, and as a sources of plant nutrients in conjunction with mineral fertilizers. This manual is written for all those concerned with the maintenance and improvement of soil fertility, especially under tropical and subtropical conditions. It contains material for use in farmer training.
