■ Abstract We highlight the complexity of land-use/cover change and propose a framework for a more general understanding of the issue, with emphasis on tropical regions. The review summarizes recent estimates on changes in cropland, agricultural intensification, tropical deforestation, pasture expansion, and urbanization and identifies the still unmeasured land-cover changes. Climate-driven lan...

this paper considers the potential problems that may militate against the adoption of organic poultry production in nigeria. factors identified include: higher risk of diseases like coccidiosis and newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...

Land-use regulations can affect property values in a variety of complex ways. In the context of laws like Oregon’s Measure 37, requiring that landowners be compensated if regulations reduce property values, the economic effects of land use regulations on property values have been widely misinterpreted because two very different economic concepts are being confused and used interchangeably. The ...

To coop with urbanization issues and the economic need for expansion, the city of Jakarta is planning to reclaim more land in the Jakarta Bay. However, the reclamation activities of some islands have barely started and already the developers are facing difficulties in finding sufficient quantities of sand as fill material. When addressing the problem of sand scarcity in the case of Jakarta wher...

Agriculture is the cornerstone of Rwanda’s economy. The authors review how the sector has changed and specifically what soil management practices are now being implemented to enhance coffee production. Coffee covers around 2.3% of total cultivated arable land, and is grown mainly by smallholder farmers on plots of less than one hectare. Rwanda produces high-quality speciality or fully washed co...

We use nationally representative survey data from two neighboring countries in Southern Africa – Zambia and Malawi – to characterize the current status of rural land rental market participation by smallholder farmers. We find that rural rental market participation is strongly conditioned by land scarcity, and thus is more advanced in Malawi than in lower-density Zambia. In both countries, we fi...

This paper studies the effects of land use consolidation on consumption growth of farm households in Rwanda. Data on 1 920 households, observed in two time periods, are used to estimate a first-differenced model using an instrumental variables estimator, which allow the analysis to account for selection bias and placement effects. Results show no significant effect of land use consolidation on ...

The presents study was aimed to create new methods for extraction and analysis of land elevation contour lines, automatic extraction of water bodies (river basins and lakes), from the digital elevation models (DEM) of a test area. And extraction of villages which are fell under critical water scarcity regions for agriculture and drinking water with respect to their elevation data and available ...
