  • 37. A long series of major water issuesChanges in availability of water resources climate variability, and change (temperature, rainfall??) ( ) land use, land cover large and small conservation works (dams, terraces,etc.)Changes in water demand and water uses abandonment of traditional technics, and social rules new distribution of population export of drinking water to the coast rapid increase in irrigated areas limited f li i d enforcement of laws fl

  • 39. Changes in groundwater rechargeThe construction of the El Haouareb big dam in 1989 completelychanged the groundwater recharge in the Kairouan plain  • in processes (location, time) • in fluxes (evaporation loss in the dam)  Before 1989 After 1989
  • 40. Changes in water demand for  agricultureExpansion of irrigated areas in public and private domains Changes in irrigation techniques fromtraditional techniques to drip irrigation, supposed to save water Changes in crops from cereals and olive trees to tomato, melon, etc., more water demanding with more benefit g f

  • 42. Which future for agriculture?Solutions must come from agriculture, that represents the most f g , pimportant water consumptionBut adaptation, interests and investments depend on many criteria:  the size of farms,  the status ( (owners, renters),  ) the crops (trees vs annual, speculative) th  li iti g f t the limiting factors ( il   t   k ) (soil, water, work power)The scientific tools (technics, economy, ...) grasp only a limited part of the multiple interacting processes. e.g. drip irrigation did not save water
  • 43. Which water management?A new water management should consider manyconstraints: Technical solutions are not sufficient Equilibrium between social equity and economic efficiencyThis should lead to the definition of a new water governanceg Shared responsibility for the use of a common good (especially in a large region) Clearer role of authorities (Min. of Agriculture) Acceptance of new rules
