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.

WaNulCAS simulation as a tool for diagnosis

The WaNuLCAS model can predict some of the biophysical benefits and consequences that are commonly attributed to agroforestry systems. The shallow rooting system of Gliricidia causes compettion (Left) for nutrients and water with maize roots. The deep rooting system of Peltophorum, leads to less competition and reduces N leaching (right).• The WaNuLCAS model version 2.0 was used to simulate different scenarios on adaily time step for 9 years for some of the described cropping systems (Table 1)established on an Ultisol at the Biological Management of Soil Fertility (BMSF)Project site (4o 31’ S, 104o55’ E), Kotabumi, Lampung, Indonesia.• An annual total rainfall of 3102 mm (1 Nov 1997 – 31 Oct 1998) was used in thesimulationsFarmers have a simple terminology for soil fertility by using the distinction 'hot' versus'cool’. A Corg/Cref ratio of 1 is a soil just derived from forest, called ‘cool’ by farmers;values towards 0 are increasingly ‘hot’, while values above 1 are ‘cooler than cool.
