A Review of effectiveness of vegetative buffers on sediment trapping in agricultural areas
In recent years, there has been growing recognition of the importance of riparian buffers between agricultural fields and waterbodies. Riparian buffers play an important role in mitigating the impacts of land use activities on water quality and aquatic ecosystems. However, evaluating the effectiveness of riparian buffer systems on a watershed scale is complex, and watershed models have limited ...
متن کاملThe Effects of Potential Land Development on Agricultural Land Prices
We conduct a national-scale analysis of the determinants of agricultural land values. The theoretical basis for the study is a spatial city model with stochastic returns to future land development. The empirical model of agricultural land prices is estimated with a crosssection on approximately three thousand counties in the contiguous US. The results provide evidence that option values associa...

متن کاملStream Sediment Sources in Midwest Agricultural Basins with Land Retirement along Channel.
Documenting the effects of agricultural land retirement on stream-sediment sources is critical to identifying management practices that improve water quality and aquatic habitat. Particularly difficult to quantify are the effects from conservation easements that commonly are discontinuous along channelized streams and ditches throughout the agricultural midwestern United States. Our hypotheses ...
متن کاملSpeculation in Agricultural Land
Agricultural land prices in many developed countries rose and then fell dramatically over a relatively short period of time in the late 1970s and early 1980s. Most of the models in the literature that describe the dynamic behaviour of agricultural land prices suggest that these sharp price movements were not completely due to market fundamentals. Many attribute part of this price volatility to ...
