Will intensifying the road network around market areas produce greater economic returns and less environmental damage than extending the road network into new areas?Rural roads promote economic development but also facilitate deforestation. To explore the trade-offs between development and environmental damage posed by road building, Chomitz and Gray develop and estimate a spatially explicit model of land use.
The objective of the Law on Land Management, Urban Planning and Constructions shall be to promote the organization and embellishment of the urban and the rural areas throughout the Kingdom of Cambodia with the purpose of assuring development of this country in the spirits of respecting both common and individual interests, private rights, observing laws and regulations, and overseeing on the construction matters, assuring through the development process an equilibrium between the cities/towns and rural areas based on their geographical conditions and special characteristics, assuring the va
The first of the series focuses on the much debated issue of forest lands. Retaining the existing forest cover, improving the quality of so-called forest land, bringing back the traditional ethos of preserving forests as part of the Indian heritage and lifestyle and making people part of the greening movement rather than policing the forests, the changing policies over the past century and their impact on the forest cover, the relevance of these policies in the context of liberalisation and structural adjustment are all addressed in this volume.
Estern Colombia, the Llanos, is constituted of broad grass formations. These big expanses of savannahs present a huge potential for extensive bovine breeding. Unfortunately, these natural pastures have a low productivity and a feeble quality, due to low fertility soils with a deficiency in phosphorus and a hgih acidity. In regard to the importance of the breeding for the region, it`s essential to know the savannahs `characteristics in order to ameliorate the exploitation which is done of them.
Reports on completed and planned research to examine farmers' perceptions of different breeds, the discretion they exercise over breed composition, and the impacts of breed perceptions on breeding practices. ILCA has recently undertaken three household surveys that shed light on farmers' breed preferences and breeding practices. The survey results indicate that farmers' breed prortfolios are the outcome of dynamic processes that vary across farmers and environmental conditions.
The potential of Crotalaria ochroleuca check for this species in other resources as a green manure crop was evaluated in a series of on-station and on-farm trials on reddish kaolinitic loam and sandy clay loam soils in Uganda. Production of the green manure by intercropping Crotalaria with either maize or beans was found to be feasible with little reduction in food crop yield and a mean Land Equivalent Ratio of 1.3. The large amounts of N in the Crotalaria indicates that large quantities of N were biologically fixed.
The impact of information techniques in all economic activities has been tremendous during the past decade. However, the potential of the multiple management methods and technologies derived from this field has not been fully realized in the irrigation sector. One area of application of information techniques concern the design and installation of Decision Support Systems (DSS). This area, used for the particular activities relating to the management of water in irrigation schemes, constitutes the theoretical background of this paper
This paper reports on a detailed sociological study carried out as the NGO (or change agent) was completing three-year projects in two sites, Nagadeepa and Pimburettewa. The study describes the change agent's strategy, and analyzes its impact and the perceptions of farmers and government officials regarding its impact. The case study is placed in a wider context, in terms of both the participatory management policy of the Government of Sri Lanka, and the lessons learned that are relevant for NGOs working in other countries as well.
This document reports the results of a small meeting of social scientists from ILCA and IFPRI held at ILCA. The workshop was conceived to summarize the results of studies previously conducted by ILCA and others, to identify priorities for future research; to provide guidance for future research - problems, methodology, locations, and resource requirements, and to consider specific proposals for future research and evaluate the areas of complementarity and/or overlap with other past or current projects.
