Sustainable agricultural and rural development in semi‐arid environment when supplementing rainfall with 200mm irrigation water per year
An Irrigation Public Perimeter, Oued Rmel IPP, was created in a semi arid region of Tunisia, providing 200mm/ year complementary irrigation (CI).Rainy season occurs from autumn to spring, with annual rainfall varying between 200 and 700mm.The potential evapotranspiration is of 1250mm.More than 90％ of days are windy.Seventy percent of the farms are 3 or 6 ha in area, rented by 1100 families with low incomes.A six hectare Research and Extension Station (RES) was created in the IPP to try different production systems with the aim to create a sustainable biophysical and socioeconomic environment by (1) CI to improve and stabilize yields, (2) introducing multipurpose tree and shrub (MPT) planting technologies, (3) adapting animal farming.
