This paper develops a soil conservation model that is relevant to smallholder farmers who apply little or no fertilizer. Empirical results drawn from northern Tanzania imply that, ignoring fertility mining problem in model specification leads to overestimation of profits for farms that apply...

The low efficiency of feedstock storage and transportation hinders commercialization of a switchgrass-based biofuel industry although the feedstock has various environmental benefits. This study develops a sustainable switchgrass supply chain that balances its economic and environmental...

This study explores the extent to which various factors affect Fijian cane farmers’ adoption of soil conservation measures. The significant factors affecting perception of the soil erosion problem are age, ethnicity, and extension education, while the significant factors affecting soil...

Understanding the economic value of avoided soil erosion in New Zealand is an important factor in policy decision making enabling the acknowledgement of the costs of erosion to the economy. This paper focuses on potential for afforestation to mitigate erosion risks on marginal agricultural hill...

Agri-environmental policy is at a crossroads. Over the past 20 years, a wide range of policies addressing the environmental implications of agricultural production have been implemented at the Federal level. Those policies have played an important role in reducing soil erosion, protecting and...

This paper studies the effects of environmental policy on the farmers soil optimal management. We consider a dynamic economic model of soil erosion where the intensity use of inputs allows the farmer to control soil losses. Therefore, inputs use induces a pollution which is accentuated by the...

In Nigeria 90% of the agricultural primary produce is in the hands of small holders cultivating between 0.8-4 hectares. Farm size expansion is limited by population pressure, land fragmentation, poor market opportunities and lack of finance. This article presents estimates of soil erosion...

A dynamic optimization framework is used to analyze integrated watershed management and suggest appropriate policies. Soil conservation, reservoir level sediment release, downstream water allocation and water quality are subject to control. Application of the model to the Aswan Dam watershed...
