Rangeland management in Tunisia : Inventory and perspectives under a climate change context
2016
Touhami, I
Tunisia rangelands, 25 per cent of the total land area, play an important role in contributing to people's livelihood. Natural rangeland ecosystems decreased in area and production. This is due to the increase of population, its needs in milk, meat and other agricultural products as well as the increase in livestock numbers and needs of fodder units. Current Tunisian rangeland ecosystems, consisted of forest and steppe ecosystems, suffer great pressure with an average overgrazing rate that exceeds 75 per cent. Projections of climate change in Tunisia for 2030-2050 horizons predict a rise in annual and seasonal temperature and decreased rainfall, with increased frequency of extreme events including the succession of dry years that can have significant impacts on perspectives and developments of the production systems and in particular the rangeland and extensive farming systems which depends largely on livestock feeds. It is concluded that current management of rangelands should be improved to reach more rational management. So, efforts are needed for rangeland management and development of their resources. It is also important to adopt a method of periodic grazing in plots limited, an integrated approach and adaptive management is required to respond to climate change
