Objective: To consolidate Hydraulic study results with the integration of the Socio-Economic and Environmental information/data. To propose options for a strategy for sustinable development,involve relevant sectors, inter alia, agriculture, enviornment, all stakeholders and NGO's to shift from technical level to policy level.

GEF/UNEP/SDC/FFEM OBJECTIVES : 2003 - 2005
 TO CONSOLIDATE HYDRAULIC STUDY RESULTS
WITH THE
INTEGRATION OF THE SOCIO ECONOMIC AND
ENVIRONMENTAL INFORMATION/DATA
 TO PROPOSE OPTIONS FOR A STRATEGY FOR
SUSTAINABLE DEVELOPMENT, INVOLVE RELEVANT
SECTORS, inter alia, Agriculture, Environment, Ａｌ
ｌ STAKEHOLDERS and NGOS
 TO SHIFT FROM TECHNICAL LEVELTO POLICY
LEVEL

21. 21
• Very high water consumption : 6 000 to 25
000 m3/ha/year
• Low performance of irrigation techniques
with water loss
• Excessive fragmentation of irrigated land
• Lack of maintenance of drainage
• Soils Not fertilised
• Main actors are family members
• Women managing the irrigated land are
limited (less than 5%).
SOCIO ECONOMY

22. 22
• Possible problems of future water
abstraction:
- Increased water cost
- Conflicts over allocation and fixing of ｗａｔｅｒ price
- Reduction in irrigation amount
- Soil salinisation (need for wash-out and drainage)
• Possible problems asscoaited with reduced
agriculture productivity:
- Reduction of income of farmers
- Increased poverty of farmers
- Increased unemployment
SOCIO ECONOMY

23. 23
Importance of wetland and their
fragility
Serious soil salinisation
Future need for restriction of
agricultural development due to
soil loss and degradation
Need for a joint survey
RECOMMENDATIONS ON
ENVIRONMENTAL ISSUES

24. 24
• Institutionalising water saving policy:
– Rational resource management
– Promotion of water-saving irrigation techniques
– Utilisation of non conventional waters
• Diversification of regional economy
• Adoption of policy of pricing and investment support

CONSULTATION MECHANISM

26. 26
APPROACH FOR THE CONSULTATION
MECHANISM
Initial development (Rome, December 2002):
development of monitoring indicators,
- development of database and models,
- promotion of studies, research and training
- Perspective for future evolution of the Mechanism
 Cooperation among technicians and building of mutual confidence
 Strategy for an integrated vision for sustainable management
 Solidarity facing the risks
 Involvement of decision makers
CONSULTATION MECHANISM

27. 27
PERMANENT STRUCTURE
 Formalized agreements or conventions on protection
of the risk areas
 Exchange protocoles and data management
 Common networks of monitoring and financing
modalities on national budgets
 Periodical updating of the management models
 Production of monitoring indicators of the NWSAS
(Hydraulic, Agriculture, Economy, Environment)
 Annual meeting of the decision makers
