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.

Role of paddy rice fields (sawah) as sediment filter in agroforestry mosaics

Exporter la citation

For predictions of downstream effect of soil erosion we need to consider various factors affecting sediment transfer. Rice fields are presumed to trap incoming sediment, therefore their role in sediment transfer should be considered in prediction of downstream effects. Sediments coming from upper slope are often deposited in sawah (= paddy rice) terraces. Sawah terraces can therefore function as a sediment trap. But, not all incoming sediment will be permanently deposited in sawah terraces; a portion of it will leave the sawah field especially during land cultivation and weeding activities. Both activities will physically disperse the deposited sediment and in turn a portion of the sediment will leave the sawah along with run-off. Knowledge of how much net sediments are permanently deposited in sawah terraces is very important for adjustment of off-site prediction of erosion from upper-slope. The objective of this research is thus to measure the sediment balance of a sawah field on annual basis. Due to funding limitations, however, this research covers only one planting season. We hope to be in a position to continue this research to complete a full one-year analysis
