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.

A framework for quantifying the various effects of tree - crop interractions

Export citation

Early assessments of the potential benefits of agroforestry at the farm level were based largely on the assumption that it is possible to extrapolate from existing information on forestry and agriculture (Huxley 1983; Nair 1993) and partly on observations of trad- itional agroforestry systems that showed increased growth of understorey vegetation (Ong and Leakey 1999; Kho et al. 2001). Various negative effects have also been rec- ognized such as competition for moisture excessive shading and allelopathy although these have attracted much less attention from scientists. Most of the evidence of benefits and drawbacks of agroforestry continues to be qualitative or indirect i.e. extrapolated from a wide range of systems creating often un- realistic expectations of the benefits of agro- forestry technologies (Garcia-Barrios and Ong 2004).
