INTRODUCTION
PPT Slide
Purpose of this paper
THE WATERSHED SETTING
Hydrologic Characteristics of Drylands
Streamflow
Riparian Vegetation
Soil Erosion & Sediment Delivery
Soil erosion reduces productivity of the land
Gully Erosion indicates advanced watershed degradation
Sediment delivery to reservoirs reduces their economic
life
Examples in Morocco
THE CHALLENGE TO MANAGEMENT
Enhancing Water Supplies
Coping with Hydrologic Extremes
Avoiding flood hazards
Coping with Droughts
IMPLEMENTING WATERSHED MANAGEMENT
In moving toward sustainable development, the biophysical
realities of these systems must be recognized, but equally important, the
necessary policies and institutional arrangements must be in place to mobilize
human activities on the land in ways that are compatible with these biophysical
realities.
Freshwater benefits to downstream areas naturally
accompany sound management of upland and riparian areas
Benefits of Watershed Management can be masked
