Maintaining drinking water quality is essential to water companies and their customers. However, agricultural non-point source pollution of waterways is a major cause of water quality degradation. In this paper we examine the feasibility of using payments financed by a water company to pay farmers to adjust agricultural land management practices to protect water quality. We use the choice exper...

The extension of urban perimeter markedly cuts available productive land. Hence, studies in urban sprawl analysis and modeling play an important role to ensure sustainable urban development. The urbanization pattern of the Greater Asmara Area (GAA), the capital of Eritrea, was studied. Satellite images and geospatial tools were employed to analyze the spatiotemporal urban landuse changes. Objec...

Human activities such as research & development, infrastructure or management are of major importance for agricultural productivity. These activities can be summarized as agricultural land-use intensity. We present a measure, called the τ -factor, which is an alternative to current measures for agricultural landuse intensity. The τ -factor is the ratio between actual yield and a reference yield...

On the basis of elaborating the process of institutional change of Chinese agricultural land and by reference to the State Theory of North, the article analyzes constituent functions for institutional activities by the state for its realization of maximization of utility and further the role of the state in the process of institutional change of Chinese agricultural land.

Improving security of tenure over agricultural land has recently been the focus of a number of large land certification programs. While the main justification for these efforts was to increase productive investments and facilitate land rental transactions, we show that if access rights were tied to actual land use in the previous regime, these programs can also lead to increased outmigration fr...

Land cover changes influence the biogeochemistry, hydrology and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland expansion, dryland degradation, urbanisation, pasture expansion and agricultural intensification. For the assessment, remotely sensed land-cover data, census data and expert knowledge were used. In tropical ...

Afforestation of agricultural lands has been one of the major land use changes in China in recent decades. To better understand the effect of such land use change on soil quality, we investigated selected soil physical, chemical and microbial properties (0-15 cm depth) in marginal agricultural land and a chronosequence of poplar (Populus euramericana cv. 'N3016') plantations (5-, 10-, 15- and 2...

The objective of this paper is to propose a spatial disaggregation procedure that will be useful in assessing economic and environmental impacts of the last CAP reform of EU agriculture(e.g., the study of water pollution due to agriculture). The proposed disaggregation method uses agricultural data in conjunction with biophysical processes to break down agricultural FADN data available at the r...

This study uses Rwandan household survey data to evaluate the impact of conflict-induced migration on agricultural productivity, as well as to assess the effect of the Rwandan government’s housing and land redistribution policy. The hypothesis that the policy improved output by a pure resource effect is tested against a human capital spill-over effect hypothesis. Time differentials in the imple...
