Aim: The study aims to
assess the relationship between land use and the land classes in the Tahtalı
Dam Protection Basinin terms of sustainable use of natural resources.
satellite images were used to determine the current land use and remote
sensing was employed to process these images.
capability classification demonstrates the natural potential of an area.
Class I, II, and III lands that are agriculturally important cover 30% of the
basin. Class IV, Class VI, and Class VII lands account for 6%, 21%, and 42%
of the basin, respectively. Class V lands covered a very small area in the
basin and they were not taken into consideration. Finally, Class VIII lands
take up merely 1% of the area. The most important kinds of land use in the
basin are forests-maquis-garrigues (62.8%), fields (28.7%), residential areas
(3.5%), greenhouses (2.3%), and water surface areas (2.7%). There is a
mismatch between the land capability classes and their use. In fact, 31% (of
200 km2) of the Tahtalı Dam Protection Basin is misused.
Failure to use lands in line with their capability classes gives rise to
certain adverse consequences. Indeed, severe erosion in 54% of the basin
takes place in sloping areas devoid of vegetation. Residential waste,
intensive use of pesticides-chemical fertilizers, and large industrial
facilities pollute dam water and cause land degradation (Pollution levels are
higher than that of Class II water).
Interpretation: In order to
prevent degradation, pollution and siltation of the dam, lands should be used
properly and sustainable alternative methods (organic farming, ecological
tourism, etc.) should be adopted by locals, particularly the farming
industry. An autonomous "Tahtalı Dam Protection Basin Forestry
Center" that can ensure inter-institutional cooperation should be
