An Awareness-Adoption Matrix for Strategic Decision Making in Agricultural Development Projects： A Case Study in Yunnan Province, China

Significant achievements have been made in generating sustainable agricultural technologies in developing countries. Usually, these new technologies have been more effective in increasing production and productivity than existing technologies. However, many new technologies considered ＇effective＇ have not been successful in alleviating the associated sustainability problems, due to poor adoption by targeted users. Success of any novel technical intervention should be judged on the basis of how widespread adoption is in the target area by targeted users. In this context, a case study identified the factors affecting farmers＇ adoption of improved technologies extended by an agricultural development project in a rural Village in Yunnan Province, China. Initial adoption/adaptation of project technologies was influenced by farmers＇ awareness of the technology. Farmers were more aware of polythene mulch, contour cultivation, intercropping and tree planting technologies than others. This led to a comparatively high initial uptake of polythene mulch, contour cultivation, sweet chestnut, and intercropping technologies. Farmers had inadequate knowledge about some Project technologies, the adoption of which was particularly low. This reveals the need for increasing farmers＇ awareness about the rationale for Project technologies to achieve greater adoption/adaptation of project technologies by farmers over wider areas. Farmers＇ testing of the technology leads to better adoption/adaptation compared to mere awareness. However, considerable time and resources are required for testing/trying technologies. This justifies the usefulness of comparatively quick and less resource demanding options for awareness creation. Development of effective cropping technologies is important for sustainable agricultural development. The success of any agricultural development project, especially in terms of improving sustainability, depends on how widely those improved technologies are adopted/adapted by farmers in the targeted region. Therefore, farmers＇ adoption of technologies should be a key criterion for judging the success of any project. The awareness-adoption matrix is a useful tool to guide research and development projects to achieve expected adoption/adaptation of technologies. Use of the matrix helps identification of weak and strong aspects of research and development projects and thus assists strategic decision-making.

An Evaluation of the Introduction of Modified Cropping Practices in Yunnan Province, China, Using Surveys of Farmers＇ Households

Problems associated with land degradation are serious in China. Sloping land in South China has experienced a decline in crop productivity by 30-60% due to soil erosion and it has been predicted that most topsoil will be lost within the next 100 years if current erosion rates continue. Considering these situations, an agro-environmental research and development project （Sustainable Highland Agriculture in South-East Asia- SHASEA） was conducted in a catchment in Yunnan Province, China, to address the objectives of increasing crop productivity in sustainable and environmentally-friendly ways. A range of cropping practices was developed and implemented in a rural upland catchment （Wang Jia）. At the end of the project, farmers were surveyed to evaluate project effectiveness. All farmers from Wang Jia Catchment, who were involved in project implementation, were surveyed. A sample of farmers working in an adjacent catchment （not associated with the project） was surveyed for comparative purposes. Farmers had different perceptions of the cropping practices employed. Contour cultivation was preferred and likely to be adopted. Others practices such as straw mulching and intercropping were seen as less appropriate and unlikely to be adopted. Polythene mulch was recognized as effective, but likely to be adopted only if financial returns were favourable. The availability of relevant information had an important impact on the extent of technology testing by farmers and their willingness to adopt the practices in the future.     

Re-examining Geos Neighbourhood for Its Energy Self-sustained Ability Through Ecological Footprints,Net Energy,and Life Cycle Assessment Tools

There are mounting evidences that human consume significant quantities of resources and have a major impact on the environment. Some research indicates that since the 1980 s human demands on the biosphere have exceeded its regenerrative capacity. One way to solve this problem is to minimize the inappropriate exploitation from environment.This essay will focus on energy self-sustained project, which is a specific way to reduce energy requirements. Energy self-sustained project refers to that energy production is equal to the amount consumed. Three concepts are quoted in the following to assess whether the project achieve zero-energy or not. First, ecological footprint, which provides an indication of the human load on the biosphere, is utilized to measure the inputs and outputs of the bioregion, which is also beneficial for defining the potential energy. Another one is life cycle assessment, which evaluates environmental load that relates to the entire life periodic system of a product, is helpful to measure the products used in the energy self sustained project. In addition, net energy, and gross resource abundance, definitions for selection, or hierarchy of different energy resources, can evaluate the new energy resources in project.Geos Neighbourhood, located in colorado, was planned as the largest net-zero energy neighbourhood in the United States. To meet the energy self sustainability,earth and sun power completely sustain the community's energy needs, and replace all fossil fuels. Compared with the traditional communities, Geos Neighbourhood minimize the adverse impact on the environment. As tools for assessment,ecological footprint, life circle assessment, and net energy, are all used to analyse the planning and design principles in the neighbourhood. By the research, the design principles and energy use in Geos Neighbourhood will be re-examined that whether the zero energy project achieves the reduction of ecological footprint, and energy self sustainability. In addition, life circle assessment will re-examine the materials used in the community also. Finally, the concept of ‘net energy' will test solar energy and earth power which is the major energy used in Geos Neighbourhood.     

Modeling Climate Change Impacts on the US Agricultural Exports

Climate change is expected to have substantial effects on agricultural productivity worldwide. However, these impacts will differ across commodities, locations and time periods. As a result, landowners will see changes in relative returns that are likely to induce modifications in production practices and land allocation. In addition, regional variations in impacts can alter relative competitiveness across countries and lead to adjustments in international trade patterns. Thus in climate change impact studies it is likely useful to account for worldwide productivity effects. In this study, we investigate the implications of considering rest of world climate impacts on projections of the US agricultural exports. We chose to focus on the US because it is one of the largest agricultural exporters. To conduct our analyses, we consider four alternative climate scenarios, both with and without rest of world climate change impacts. Our results show that considering/ignoring rest of world climate impacts causes significant changes in the US production and exports projections. Thus we feel climate change impact studies should account not only for climate impacts in the country of focus but also on productivity in the rest of the world in order to capture effects on commodity markets and trade potential.     

Setting Agricultural Research Priorities： The Case for the Agricultural Sector in Swaziland

The study determined the research priorities in Swaziland agricultural sector. Data collection used existing documents on agricultural research prioritizing, Nominal Group Technique and modified Delphi technique, with analysis of data using content categorization and, group and individual ranking of submissions. Findings showed the agricultural priorities from national policies are tied-up with mitigating the effects of HIV and AIDS on food security, reduction of poverty and, sustainable development. The findings also revealed forty-three field crops areas needing research. Seven horticulture areas and eleven livestock sector areas were of high priority. A considerable number of research areas in field crops, horticulture and livestock indicated that the current research system has not adequately addressed research needs, despite efforts made by the private sector, University of Swaziland and Ministry of Agriculture and Cooperatives, for Swaziland to achieve self-sufficiency in food production. Recommendation was that the identified research priorities should be used as basis for directing the limited resources in conducting agricultural research. The participation of all stakeholders would facilitate efficient use of resources and facilitate collaboration amongst research institutions. The University of Swaziland should develop research priorities aligned with national policies and objectives, to facilitate funding for research by both government and donor agencies.     

Revealed Comparative Advantage and Competitiveness in Chinese Agricultural Sectors

This paper examined the competitiveness of Chinese agricultural products, in relation to the rest of the world, based on the index of revealed comparative advantage, using lots of data during period of 1980 to 2000. The index is useful in identifying the demarcation between comparative advantage and comparative disadvantage, though a problem exits when using it. China is shown to have a comparative advantage in a range of agricultural products, including edible vegetables and tea. This complements the findings of those studies that have used price and cost based on approaches in identifying competitiveness in agricultural products. Results indicated that the RCA values had been weakening over the 21-year period. These have vastly different implication for the future reform in China＇s agriculture,
