Rural settlements are the main carriers of agriculture, rural areas and farmers; thus, optimizing the production and living space of rural settlements is highly significant to rural development. Taking the effective allocation of resources as the starting point, a suitability evaluation system of rural settlements, based on accessibility of production and living, was proposed in this study to provide scientific basis for the optimization of production and living space. The accessibility of production and living was measured by an im- proved two-step floating catchment area method, which considered proximity and availability based on the inclination of rural residents. The suitability evaluation system consisted of traditional suitability evaluation and newly proposed limiting factor identification based on the loss score proportion of suitability. Tingzu Town of Hubei Province, China, was chosen as the case study area. Based on the re- suits of the suitability evaluation system, corresponding suggestions on rural land consolidation, industry division, as well as the layout of health care and education facilities were proposed to optimize the production and living space of rural settlements in Tingzu Town. It is found that the suitability evaluation based on accessibility of production and living is more scientific and accurate than the traditional ones which significantly overestimate production and living convenience. Moreover, the limiting factor identification can help us put forward suggestions according to local conditions and bring about the highly targeted optimization of production and living space of rural settlements. 展开更多

In 2005, 10 new cassava varieties were officially selected and released to farmers in Nigeria for high root yield, high dry matter content and acceptability for food. This work compared in three on farm locations, the root and stem yield of these varieties together with an old improved variety currently in farmers' field. In all the locations, root yield of all the new materials were significantly higher (P 〈 0.05) than the old improved variety. The root yields of the new varieties were between 40%-50% higher than the old improved varieties. Overall yield advantages of the new materials over the old improved material ranged between 40%-150%. Stem yield figures showed significant variations with few of the new varieties producing higher stem yield in comparison with the old improved variety due to inherent growth pattern. Figures for tuber girth and node numbers per unit of stem were similar. The high yield levels of the new varieties might lead to high demand for stems indicating the likely wider spread and higher demand for varieties with high stem yield potentials. 展开更多

We evaluated the pathogenicity of six strains 1. fumosorosea to determine their potential as biological control agents of A. ludens by performing bioassays under laboratory conditions (25 ± 2 ℃, 60± 5% R.H and 12:12 h L: D) exposing larvae and pupae to a concentration of 1 × 10^8 conidia per milliliter using three different methods: direct spraying, spray of soil and submerged for both instars. The results showed that direct spraying method Pfr-612 strain showed the highest mortality (47%) in pupae while for larvae was strain HIB-27 to 46%. Regarding spray of soil Pfr-612 strain showed the highest percentage of mortality for pupae and larvae with 45 and 57% mortality, respectively. Finally, for the submerged method in pupae HIB-27 strain showed 62% mortality whereas in larvae HIB-32 strain showed 46%. These results indicate that A. ludens is susceptible in at least two instars to L fumosorosea and make this fungus a promising agent for control of the Mexican fruit fly. 展开更多

Agricultural ecosystems are the largest managed ecosystem in the world.The sustainable development of agriculture is significant to the reversion of dramatic loss of biological diversity in the world.Globally Important Agricultural Heritage Systems (GIAHS) project launched by Food and Agriculture Organization (FAO) of the United Nations is among the global efforts to conserve and dynamically manage the specific agricultural knowledge system and landscapes.Ministry of Agriculture,Forestry and Fisheries (MAFF),Japan stressed the environmental concern of conventional farming practices in Japan in 1992.Noto Peninsula and Sado City were designated as two new GIAHS pilot sites in Japan as part of local level initiative to preserve the traditional agricultural systems in 2011.This paper reviewed the development process of sustainable farming in Japan and analyzed the challenges and new possibilities to its further extension.The current situation of various sustainable farming practices:such as farming with reduced input of chemical fertilizers and pesticides to conserve rich biodiversity,and organic farming,were reviewed.Emphasis was given to the sustainable farming practices in Hokuriku region,in particular,Ishikawa Prefecture and Sado City in Niigata Prefecture.Based on the recent official documents,reports and research papers,policy implication was brought forward.The challenges of sustainable farming practices and market valuation of sustainable farming products were analyzed.It was concluded that the environmental concerns of farmers and consumers are key to extend the sustainable farming practice in Japan.Conversion to bottom up policy making process paying attention to farmers'interest with involvement of multi stakeholders including government,researchers and private sectors is effective for sustainable farming extension. 展开更多

We set forth the macroeconomics evaluation of floods (MEF) model, a new model to assess and evaluate the impact of floods on GNP growth. This model points to a new, more concrete approach to measure the economic impact of floods. Up to now, the measurement has been subject to a great deal of uncertainty. The main contribution of the model is to significantly reduce this uncertainty by mea- suring the impact with four well-defined, economically intuitive indicators. To illuminate and demonstrate its promise, we employ the model to evaluate and analyze the impact of two major floods on the economy of the People's Republic of China. Our MEF-model analysis indicates that the floods of Zhangshu and Jiangxi in 2010 caused greater economic damage than the floods of Central South China in 1931. Going forward, MEF-model simulations are a valuable tool for estimating the effect of potential future floods in the PRC and elsewhere. 展开更多
