Displaying 601 - 605 of 1605Vegetable production in the Red River Delta of Vietnam. I. Opportunities and constraints
An overview is given of the natural, socio-economic, agronomical and marketing conditions for vegetable production in the Red River Delta (RRD) of Vietnam. The seasonal variation in temperature in the RRD is the main determinant for the production season of vegetables. Heavy rainfall in the hot season increases production risks, as it may physically damage crops. Frequent rainfall in this period may enhance disease incidence. Landholdings are small and individual plots are the smallest of Indochina. Vegetables typically are produced in flooded rice based systems.
On markets and government: property rights to promote sustainability with market forces
There are many different images of the livestock industry and many persons are unhappy with the outcome of the market process. Instead of explaining why the market leads to the current outcomes, it is wise to be prepared that politics will rearrange the property rights in order to produce different outcomes of the market mechanism. In this essay, I show that there are market processes that contribute to a more sustainable way of farming, and that these processes can be reinforced. There are also unsustainable public policies that can be liberalized.
framework for evaluating and designing collaborative planning
Collaborative planning processes have been criticized for inefficiency, but attempts to improve them in planning of urban nature have been limited by lack of usable evaluation methodologies. This paper presents a framework for evaluating and designing collaborative processes in strategic planning of land use and nature areas. A framework with four key perspectives and their success criteria was developed with the help of literature and data from interviews and focus groups in two case areas in the Helsinki metropolitan area, Finland.
Strategic Environmental Assessment in Latin America: A methodological proposal for urban planning in the Metropolitan Area of Concepción (Chile)
This work describes a methodology for Strategic Environmental Assessment of urban areas in Latin America based on the recently approved European Planning Directive, and applies it to the Metropolitan Area of Concepción (Chile). The method is based on the Land Suitability Index (LSI), a cartographic GIS-based index originally developed for the region of Barcelona (Spain) and aimed at determining the suitability of each point in a region for urban development, considering three sub-indexes: (i) Naturalness, (ii) Ecological Connectivity and (iii) Natural Risk.
Prospects for arable farm uptake of Short Rotation Coppice willow and miscanthus in England
Biomass will play a role in the UK meeting EU targets on renewable energy use. Short Rotation Coppice (SRC) and miscanthus are potential biomass feedstocks; however, supply will rely on farmer willingness to grow these crops. Despite attractive crop establishment grants for dedicated energy crops (DECs) in the UK, uptake remains low. Drawing on results from an on-farm survey with 244 English arable farmers, 81.6% (87.7%) of farmers would not consider growing miscanthus (SRC), while respectively, 17.2% (11.9%) would consider growing and 1.2% (0.4%) were currently growing these crops.
