We illustrate a strategy for valuation of forest ecosystem services by studying the demand for its weak complement, agricultural labor –a commodity that has market prices. In our case study forest protection in Ruteng Park of Flores, Indonesia, provides soil conservation benefits to farmers living near the protected area. Econometric analyses of forest hydrology and household data shows that so...

wind erosion is a significant problem on 20 million ha of iran, especially in central plains and coastal areas. winderosion samplers, meteorological equipments and measurement procedure have been developed over the last twocenturies to measure the particles moving across the field in modes of creep, saltation and suspension. in recentresearch as the first technical measurement in iran, wind ero...

Agricultural soil loss and deposition in aquatic ecosystems is a problem that impairs water quality worldwide and is costly to agriculture and food supplies. In the US, for example, billions of dollars have subsidized soil and water conservation practices in agricultural landscapes over the past decades. We used paleolimnological methods to reconstruct trends in sedimentation related to human-i...

Abstract Alteration of land-use land cover pattern causes severe consequences on the hydrological system by modifying rainfall-runoff in a region. The study aimed to investigate impact land-cover dynamics runoff generation different geomorphic divisions Panchnoi River basin. used Soil Conservation Service-Curve Number method estimate basin GIS platform. This observed that conversion zones signi...

Understanding how hydraulic factors control alluvial river meander migration can help resource managers evaluate the long-term effects of floodplain management and bank stabilization measures. Using a numerical model based on the mechanics of flow and sediment transport in curved river channels, we predict 50 years of channel migration and suggest the planning and ecological implications of tha...

globally, soil erosion is one of the most important environmental problems which is threaten soil and water resources. soil properties are main parameters to affect runoff and soil erosion processes. so, this study was conducted to investigate the effects of some soil properties on runoff and soil erosion in the forest lands located in vicinity of sari city. rainfall simulator was set in 15 ran...

The main purpose of the present study was to assess the ecological capability of agricultural soils using geographic information system (GIS). This research was conducted during 2014 in Hamedan Province, Iran. A cross-sectional study was conducted mapping the 10 factors of soil characteristics (texture, depth, erosion, and aggregation, percentage of slope, direction of slope, height, soil salin...
