In Southern countries, trees are often cultivated with horticultural crops (e.g. mango, citrus, papaya) in multi-strata systems, such as Creole gardens (West Indies) or clove-agroforestry systems (Madagascar). These systems are particularly important in tropical regions to ensure nutritional balance, nutrients and vitamins inputs.
Our objectives are to i) produce an evidence map of the knowledge and practices on such systems and produce a typology of the systems around the world.
We hypothesize that :
The characteristics of the system (complexity, cultivated species, etc.) and their performance differ according to agro-ecological zones.
The experiments detailed in the scientific literature represent only part of the diversity of systems observed locally.
Literature review, Evidence map and meta-analysis of Horticulture-Agroforestry systems in the tropics.
Objective : Global and exgaustive assessment of scientific available knowledge on agroforestry-horticultural systems.
Prospecting campaign and analysis of experts and farmers’ knowledge on clove-Agroforestry systems
Objective : Assessment of farmer knowledge and practices on agroforestry-horticultural systems in Madagascar, Mayotte and the Comoros
An open-acess literature database on scientific knowledge on horticulture-Agroforestry systems.
A precise description ok knowledge and knowledge gaps on theses systems
A Quantification of the performance of the systems
A precise typology of Horticulture-Agroforestry systems in the tropics
A quantification based on probabilistic expert elicitation of the performance of clove-tree agroforestry systems in Madagascar
Creation of a multi-institutional working group on horticultural -agroforestry systems.
