Özet
Windbreaks are commonly used to prevent wind erosion; however, the windbreaks cannot be created under fragmented field conditions. Turkey has accelerated land consolidation in recent years. Land consolidation offers other opportunities apart from improvement of the agricultural structure, such as block boundary arrangements that are serially perpendicular to the wind direction and parallel to each other. For years, this aspect of the consolidation project was not considered to be important. In Turkey, land consolidation, forestation for windbreaks, and fanner training projects were firstly performed in Karaman Yollarbasi. To create windbreaks, block boundaries were planted with the species of Acer pseudoplatanus L., Fraxinus excelsior L., Cedrus libani A. Rich., Robinia pseudoacacia L., and Elaeagnus angustifolia L. However, 40% of the trees died due to drought within four years, and the deaths of most of the trees left problematic gaps in the windbreaks. The highest survival rates were observed in E. angustifolia and R. Pseudoacacia, whereas C. libani was the most sensitive plant. The height of E. angustifolia and the drought resistance of C. libani are not appropriate without irrigation. It was observed that the enrichment of the consolidation project's scope, such as maintenance of the plants and land allocation for windbreaks, was needed to improve the effectiveness of the project. On the other hand, general index of erodibility is high in Central Anatolia, due to its high textural and analytical erodibility, semi-arid climate conditions, fallow practice, low vegetation cover, and severe wind events. The most critical months in the study area are April, May, June, July and August. The number of wind events that exceed threshold wind velocity occur more in April than in the other months. Consequently, basic precautions should be taken before the realization of desertification, such as grassland restoration, restricting grazing, increasing vegetation cover, and farming or promoting more sustainable forms of these activities, afforestation, and land consolidation.
