In order to encourage the farmers to engage in coo-agriculture, it is necessary to establish an eco-compensation mechanism for them. As the compensation standard is one of key issues in establishing eeo-compensation mechanism, this paper calculated the standard based on the farmers＇ willingness to accept （WTA） and the input-output analysis of eco-compensation. We took the traditional rice-fish eco-agriculture as the research object, conducting field surveys in Hani Terrace of Honghe County. Through the questionnaires in 2o11, we obtained the farmers＇ willingness to accept government compensation and market compensation. Then, the research evaluated the output of eco-compensation, the economic value of rice-fish paddy ecosystem services. Finally, under different market compensation standards, we compared the input and output of government compensation. The results show that, in 2011 the government should to pay farmers 7462 yuan.ha^-1·a^-1 to meet their willingness, but the output （ecological benefit） was only 7393 yuan.ha^-1·a^-1. However, whenthe rice price increases 1 yuan·kg-1 because of the limited use of chemicals in the next year, the government just has to pay farmers 4062 yuan.ha^-1·a^-1 and the surplus will be 3331 yuan.ha^-1·a^-1.展开更多

R ice-duck-fish symbiosis has been promoted in several developing countries as a way of increasing incomes for rice farmers, but investigations of its value have mainly focused on direct economic＇ benefits, such as food and raw material production. Few studies have been conducted on the estimation of indirect services provided by rice-duck-fish complex ecosystem. The gas regulation service and its economic values provided by rice-duck-fish complex ecosystem were studied in Wuhan, China. The major components of gas regulation are O2 emission and greenhouse gases （GHGs, CO2） regulation. The results show that O2 emission from different treatments （including rice-duck （RD）, rice-fish （RF）, rice-duck-fish （RDF） and rice （CK）） ranged from 26,370 kg/ha to 33,910 kg/ha per year. with an economic value of 10,050-12,920 yuan/ha per ）,ear （Chinese currency： 1 euro =10.2475 yuan, August 28, 2007）. The net GHGs exchange varied from 1,200 to 3,320 kg/ha per year; and its economic value ranged from 1,040 yuan/ha to 2,900 yuan/ha per year Consequently, the total economic value of gas regulation provided by symbiosis complex ecosystems ranged from 11,090 yuan/ha to 15,820 yuan/ha per year. and the maximum overall economic value of gas regulation was provided by RDF complex ecosystem. The work will be useful for further understanding of the functions of rice-duck-fish complex ecos.vstem services and supplying the theoretical references to agricultural policy.展开更多

This paper aims to explore how to realize sustainable tourism development in agricultural heritage site through identifying current problems in GIAHS site. and making constructive recommendations for coupled development of heritage preservation and economic development. Field survey was carried out and data was collected through field questionnaire surveys of tourists and residents in Longxian Village of Qingtian County, as well as interviews of residents with semi. structured questionnaires for their perceptions and attitudes to tourism development. The following results are got： （1） the tourism industry is still at its early state of Non, tale tourism （enjoy and experience authentic country life- style）, under very limited administrative management; （2） what attracts visitors most are delicious.fish and beautiful natural environment, but not agricultural heritage itself; （3） most tourists eome from adjacent areas and stay. only half day, many of whom pay their visits twice or more; （4） a few local residents take part in the activities of tourism industry, but in very limited manners even if they do. Current patterns of tourism development are casting negative impacts on agricultural heritage. Conservatton of agricultural heritage should be put in the first place for sustainable tourism development.Agricultural heritage, as a key attraction, should be taken as the focus for tourism development. The important thing is to change the present Nongjiale tourism into real heritage tourism, to establish a cooperative mechanism among different stakeholders. and to increase local residents＇ income through engaging in tourism industry.展开更多

The integrated rice ＋ fish system developed by the Apatani tribe of Ziro valley, Arunachal Pradesh, Northeastern India is such a unique system. Faced with shortages of their staple food items （rice and fish）, these subsistence farmers developed this ingenious system--in preference to the wide-spread shifting cultivation in the region--by capitalizing on the good water supply （from rainfall supplemented by natural flow from hills surrounding the valley）. Two rice crops are grown annually and fish is reared in paddy fields during the main rainy season. Crop residues and animal wastes are the sources of nutrients to crops, chemical fertilizers and insecticides are not used. Over the years, rice yield has been stable at about 3,700 kg.ha-1.year-1. Recently, UNESCO has tentatively added the valley as a ＂world heritage site＂ recognizing its ＂extremely high productivity＂ and ＂unique＂ ecological preservation. The resilience and the sustainability of the system could be attributed to efficient nutrient cycling and nutrient input through water seeping in from surrounding hills, which have not been, but deserve to be, quantified.展开更多
