Windbreak Hedges at the Coastline – South Madagascar Androy region (South-Madagascar)

Titre : Windbreak Hedges at the Coastline – South Madagascar Androy region (South-Madagascar)

Pays : Madagascar

Contexte
The Androy region covers a zone of about 20 000 km² to the extreme South of Madagascar. It is a zone characterized by a semi-arid climate which is partly justifiable by the foehn phenomenon provoked by the “anosienne” Chain1. A violent wind coming from the South,called Tiokatimo also provokes drying up, erosion and sand dunes. Wind erosion The scarcity of water is the particularity of this region : underground water most often brackish, low rainfall level and uncertain (between 300 and 600 mm per year), no river or permanent water ways. The main economic activities of that enclaved region are agriculture (corn, cassava, sorghum, sweet potato) and husbandry. One can divide this region into three zones : a sedimentary zone in the South, an intermediate zone and a crystalline zone in the North of the region.

Résumé
The South of Madagascar is a semi-arid zone submitted to a dry and hot wind. The practice of agriculture there is difficult and the population is regularly subject to the risks of food insecurity. The windbreak hedges, at the level of the coastal zones, constitute a means of limiting the strengths of the wind which destroys crops and dig out arable soils. The FASARA project associates itself with farmers to find out the best combinations of species to be used, both to fight against the wind but and also to benefit from the various advantages offered by the properties of these species

Descriptif
The windbreak hedges are put in place around the crops plots. In the beginning, implanted alongside the contiguous plots, they are henceforth put in place around the individual plots because that operation requiring the coordination of different land owners was difficult. The everlastingness of the hedge is supposed to be linked to the interest of its different uses for the farmer. That is why it was chosen to install the hedges mixing different species with different functions, each of it having, at a minimum, to assure a good protection against wind.

Partenaire (s) : The Support Program to the Agricultural Networks and of Improvement of Food Security in the Androy Region (FASARA) is put into implementation in the Androy region by the Group of Research and Technological exchanges (GRET) since December 2005 and until the end of the month of May 2009. This project, financed by the European Union, comes in the continuation and the extension of the activities of agricultural component of the project « South Objective “. One of the activities of the FASARA project consists in promoting the development of windbreak hedges
