Abstract : |
The starting point of this research was to examine the sustainable use of limited and irresistible resources, the land and investigation of the factors that affects land use. The main aims of the research were to make up farm plans with multi goals regarding sustainability; to determine sustainable cropping patterns which comply with sustainable land use economically and ecologically with least sacrifice possible; suggesting agricultural and environmental policies concerning realization of economic and ecological sustainability of agricultural lands. This research was carried out in the district of Menemen, Izmir, Turkey. Farm plans that were obtained by goal programming models and linear programming in the aspect of sustainability of agricultural lands have given the same results. In the models that minimize fertilizer and pesticide use which effects sustainable use of agricultural lands in a negative way less income was brought by under the existing circumstances. According to the results it might be claimed that when the optimal farm plans are realized the sustainability of the land will be enabled. In the models that do not break sustainable land use but minimize the cost for fertilizers and pesticides; to increase the income and to put unused land in use again new alternative crops should be added to the existing one. Farmers' enthusiasm and belief in this issue are important. It was observed that most farmers were carrying out some rehabilitation activities for their lands and reducing use of fertilizers and pesticides., The starting point of this research was to examine the sustainable use of limited and irresistible resources, the land and investigation of the factors that affects land use.
