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.

Simulation of agroforestry systems with sugarcane in Piracicaba, Brazil

Sugarcane (Saccharum officinarum) occupies large areas of tropical regions as a single crop, and there is a lack of research on its cultivation in agroforestry systems (AFS). Thus, the use of simulation models to investigate its potentialities and restrictions is an important phase of evaluation. The Water, Nutrient and Light Capture in Agroforestry Systems (WaNuLCAS) model was used to investigate long-term biophysical interactions and system performance of sugarcane–rubber (Hevea brasiliensis) and sugarcane–eucalyptus (Eucalyptus grandis) alley cropping. Each system was simulated for 20 years in two soil types of Piracicaba, Brazil. The effects of light and soil water on plant growth were evaluated. Outputs of the mature phase of the system were compared to results of on-farm sugarcane-tree trials. Simulations showed a strong competition in the AFS and that light and soil water are limiting factors. Competition for these resources increased as the trees grew and it depended on tree biological characteristics and management of the systems. WaNuLCAS was an useful tool to speculate about the systems, to identify limiting factors, qualitative tendencies, and management strategies, but it presented limitations to quantitative analysis.
