Assessing the Land Consolidation Projects from the Perspective of Farmers (A Case Study in Artova District of Tokat Province in Turkey)

Land consolidation is a powerful and effective tool in solving the fragmentation problem of agricultural lands to form a larger, more rational and efficient land for the farmers. The benefits of land consolidation projects are providing access to parcels, efficient use of water resources, real location of parcels, and reducing the costs of irrigation and drainage projects. Although not sufficiently successful, the land consolidation projects in Turkey had been initiated in 1961. This study was aimed to measure and assess the knowledge, expectation and attitudes of farmers on the land consolidation project planned to be implemented for some villages in Artova District of Tokat Province, Turkey. The study was carried out in Taşpınar and Aşağı Güçlü villages which were included in the consolidation program. In these villages, 62 farmers were selected by proportional sampling method out of 175 producers registered in the Farmer Registration System (FRS) and, face to face questionnaires were carried out with them. The results indicated that the producers support the project primarily due to the convenience in irrigation and increasing the efficiency of mechanization. Chi-square analysis revealed that the problems caused by disadvantages of fragmented land structure, importance of land integrity and the experience on a previous consolidation project area are important for the producers supporting the land consolidation project.

Soil Moisture Characteristics of a Typical Slope in the Watershed of the Loess Plateau for Gully Land Consolidation Project

To clarify the characteristics of soil moisture in the slope of watershed of the gully land consolidation watershed, and to further guide the implementation of the gully land consolidation project and vegetation restoration in this area, this study selected a typical slope of gully land consolidation watershed as the research object. The soil moisture of different slope positions was monitored and analyzed, and its temporal stability was analyzed. The results showed that: 1) The average soil moisture of different slope positions increased with the increase of soil depth, and the variability showed an increasing-decreasing-increasing trend, and the variability was the smallest at about 70 cm from the surface with weak variability, and the soil moisture variability in other layers is moderate. 2) On the slope, the distribution characteristics of soil moisture content were as follows: upslope <middleslope <downslope position. The differences of soil moisture between the upslope and downslope, midslope and downslope were significant. 3) The temporal stability analysis of the soil moisture showed that there is high stability between August and September of the soil moisture of the 0-50 cm and the correlation is extremely significant, while the soil moisture content of 50-100 cm range has a significant correlation between May and June. 4) The time stability of soil moisture in the middle slope position is the highest, followed by the upslope position, and the time stability in the downslope position is the lowest. 5) The best time stability point in the study area is the M3 point of the middle slope.
