This paper estimates the capitalization of the Single Payment Scheme (SPS) into land values. The theory suggests that the relationship between the SPS and land rents is non-linear and discontinuous, because the SPS impact on land values depends on many factors, such as policy implementation details, market imperfections and institutional regulations. In empirical analysis we employ a unique far...

This study aims to identify the landscape ecological determinants related to Oncomelania hupensis distribution, map the potential high risk of O. hupensis habitats at the microscale, and assess the effects of two environmental control strategies. Sampling was performed on 242 snail sites and 726 non-snail sites throughout Qianjiang City, Hubei Province, China. An integrated approach of landscap...

This paper provides new perspectives on USA landlord–tenant contracting, where technical change is creating scale economies in farming and farm enlargements, and results that are important to the sustainability of land use and environmental quality. We develop a conceptual model of landlord–tenant contracting that emphasizes minimizing transactions costs and setting incentives for effort when t...

Grabbing of pastoralists’ traditional land to put it under the commercial farming system, which has widely been adopted as a development and investment strategy in Sudan, is creating a cruel dilemma of increasing both resource conflict and environmental degradation. This is one of the fundamental reasons that the country has earned the reputation as a home of bloody c...

The collapse of collective farming in Russia after 1990 and the subsequent economic crisis led to the abandonment of more than 45 million ha of arable lands (23% of the agricultural area). This was the most widespread and abrupt land use change in the 20th century in the northern hemisphere. The withdrawal of land area from cultivation led to several benefits including carbon (C) sequestration....

Concern among state legislators about rural development and rural land use is not new. In many states, agriculture remains an important feature of the economic, cultural, and political landscape. As rural incomes, populations, and prosperity have declined, states have adopted a variety of policies in response. Rural land and development policies in most states, however, are often more symbolic ...

Managing a catchment for drinking water supply with a high proportion of agricultural land use is a difficult task if one has to maintain a reasonable balance between water quality demand and consequent restrictions for the farming industry. In this paper, we present a neural net-based method for finding good approximations to solutions of this problem. This method is capable of ‘inverting’ a h...

While Asian food economy has been experiencing significant transitions, little transformation occurs in farm land operation. However, recent rapid emergence of middle and large farms in many regions of China is striking. Overall goal of this paper is to understand small-scale farm transformation in China based on a unique dataset surveyed in Northeast and North China. The results show that the ...
