CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

The potential of agroforestry for soil conservation: part 3. Soil changes under agroforestry (SCUAF): a predictive model

Exporter la citation

The paper describes the objectives, structure and functioning of a computerized model for prediction of soil changes under specified agroforestry systems within given environments. It provides estimates of changes in soil organic matter, represented by carbon, and soil erosion, together with the response of plant growth and harvest to soil changes. The model is intended to assist in the design of agroforestry systems, for research or development, by predicting the effects of alternative design and management options. Inputs to the model cover the physical environment, the agroforestry system (spatial or rotational structure, removals) and initial plant growth. Outputs are estimates, for any specified period, of changes in soil humus carbon, erosion, plant growth response, and harvest. Examples of modelling are given, including spatial and rotational systems, and application to non-agroforestry systems. The model operates on MS-DOS/PC-DOS microcomputers and is available on diskette
