Water harvesting is the collection of runoff for productivity purposes, instead of runoff being left to cause erosion. In arid and semi-arid drought-prone areas, micro-catchments are widely used as a water harvesting method to improve rangeland condition. The aim of present study was to investigate the effects of micro-catchment on ecological indices of rangeland health in Ghick-Sheikhha, Jirof...

in order to evaluate the impact of time of weed control on yield and yield components of two rapeseed cultivars (zarfam and opra) two separate experiments based on each cultivar conducted at shahryar (karaj). the experiment was carried out based on rcbd with three replications and six treatments for each cultivar. treatments were exerted on the different phenological growth stages including the...

Introduction: Rangeland ecosystems provide multiple ecosystem services, including feed resources for wild and domestic herbivores in semi-arid areas. However, under the ever increasing environmental changes, the impact of rainfall variability on the productivity and vegetation dynamics of rangelands are the great challenges that pastoral community are facing today. As a result, the potentials o...

This article reports a rapid method for rangeland assessments in Kenya, Ethiopia and Uganda by harnessing pastoralists’ indigenous knowledge among the Orma, Afar and Karamojong pastoralists. The study developed and evaluated a methodological framework for conducting joint assessments with pastoralist range scouts. The framework has four components: selection of ecological and anthropogenic indi...

evaluation of range conditions and plant diversity circumstances can help to rangeland managers who establish their managerial approaches on the basis of ecological capabilities of rangeland ecosystems. hence, surveying of rangelands was done in four sites of northern alborz mt. including western alborz (masooleh site), west to middle alborz (javaherdeh site), central area (polour site), and ea...
