INDICATORS FOR SUSTAINABLE DEVELOPMENT OF THE WATER
RESOURCES (CASE STUDY: BLACK SEA
WATER MANAGEMENT DISTRICT)
Panka Babukova – PhD Student "Planning and Organization of the Territorial Systems - Environmental Management"
Sofia University “St. Kliment Ohridski”, Faculty of Geology and Geography, Department Regional and Political Geography
“DRIVING FORCE – PRESSURE – STATE - RESPONSE” MODEL
DRIVING FORCES:
CLIMATE:• Air temperature;• Precipitation ANTHROPOGENIC:• number, density and distribution of the population;• GDP and GVA by economic sectors
PRESSURE:WATER ABSTRACTION
by economic sectors
WATER LOSSES
STATE:
AMOUNT OFWATER RESOURCES
WATER SUPPLY REGIME
RESPONSE:
WATER MANAGEMENT POLICIES:• Ecological minimum of river runoff• Consumption and supply management• Water prices• IWM
IMPACT:
WATER STRESS
BLACK SEA WMD IN NUMBERS:
• Area: 20 760 km² (18.7% of Bulgarian territory);• Population: 1 339 999 persons /2007/ (17.5% of Bulgarian population);• GDP: 7 816 345 thousand BGN (15.8% of Bulgarian GDP /2007/);• GVA: 6 389 501 thousand BGN (15.8% of Bulgarian GVA /2007/).
