Factors Affecting the Adoption of Conservation Measures in Soil Erosion Control: A Case of Orchard Lands of Chehel-Chay Watershed
1- INTRODUCTION Soil as one of the most important inputs in agricultural production process plays an important role in the quality of production operation, food security and sustainable development. On the other hand, soil erosion as one of the environmental agriculture issues has been intensified with increasing population and transforming to intensive forms of agriculture in recent years. Mi...
متن کاملDetermination of Main Agents Affecting Soil Erosion in Rainfed Land of Kermanshah Province Using Rainfall Simulator
In recent decades, low-yielding rainfed farms have become known as the main sources of sediment production and soil erosion in the country. Therefore, more research is needed on the factors affecting erosion and sediment production in these areas. This research was carried out with the aim of studying the effects of slope and rainfall intensity on erosion between rainbow trout in test farms in ...
متن کاملAdoption of Soil Conservation Technologies among Farmers in the Upper East Region of Ghana
Soil erosion is one of the most important forms of land degradation that threatens continued and sustained agricultural production in Ghana. The most severely affected areas are the three northern regions especially Upper East Region, where large tracts of land have been destroyed by water erosion leading to soil depth reduction and decline in soil fertility. This study was carried out in Talen...

One of non-forage functions of rangelands vegetation is soil conservation and prevents it from erosion. Water soil erosion has economic, social and environmental implication due to both on-site and off-site effects. So, the objective of this study was to assess the on-site effect of water erosion on conservation function of summer rangelands vegetation, using a combination between economic valu...
متن کاملSeverity and Yield Impact of Soil Erosion: Evidence from Northern Ethiopia
Farmers must perceive soil erosion as a problem before they will invest in preventing it. However, perceptions are often overlooked in the conservation literature. This study analyzes the levels and determinants of farmer perceptions of soil erosion in northern Ethiopia. Results are based on a survey of 250 farmers managing 900 fields during the 1995-96 cropping season. Farmer perceptions of th...
متن کاملDesigning a multi-objective optimization model of Management Canopy, based on genetic algorithms Approach to soil conservation - Case study: Kerman- Roodbar watershed
Reducing the amount and intensity of surface runoff, thus reducing erosion is one of the important aspects of natural resource management, watershed management and soil conservation. Land surface conditions and particularly vegetation is Mitigating or aggravating factor in erosion. Studies on the effect of ground cover to reduce erosion rates indicate that is not necessary to ground cover to re...
