This region has the highest density in population, industry and towns in China, and the large export-oriented economy makes itself a strategic importance while China enters into international markets. The problems facing to this region include arable land reduction, land degradation aggravation, high percentage of built-up land with high rate of expansion, expanded non-point pollution, deteriorated water quality, decreasing biodiversity, destroyed ecosystems, severe air pollution, frequently occurred acid rain, and multi-pollutants. The important research fields in the near future should include a) influence of high-intensity exploitation of resources on changes of environment quality and its feedback; b) interface processes, key mechanisms and adjustment principles for degradation of water-, land-, and air-resources and environmental quality; c) evolvement processes and nurturing theory of biodiversity and ecological resources; and d) spatio-temporal variation and human-induced effects on regional resources and environment quality. Strategies for sustainable development in the region are as follows: a) controlling to ensure basic cultivated land area; b) enforcing remediation of polluted water environment, and controlling non-point pollution; c) strengthening ecological construction and ecological security; and d) controlling multi-pollution and preventing trace toxic pollutants.展开更多

Based on field survey and 946 questionnaires from peasant household conducted in the case study area of Zhaotong, Yunnan Province, the paper has analyzed the basic characteristics of the rural livelihoods, including the asset base status, the income-generating activities, the energy consumption pattern, and the fertility behavior, in the upper reaches of the Changjiang (Yangtze) River. The micro-level findings show the conflicts among extensive agricultural development models, rural energy consumption structures heavily relying on biomass and the environment protection. The conversion of cropland to forest and grass program(CCFGP) has exerted an important influence on the livelihoods of the peasant households, but its design has given little considerations to their long-term livelihood sources, which will affect its sustainability to a great extent. From the perspective of sustainable livelihoods framework, the objectives that must be addressed in the ecological shelter construction in the upper reaches of the Changjiang River should include, first, facilitating access of peasant households to credit, technology and public services, second, encouraging the peasant households to adopt agricultural technology with environmental benefits and strengthen resources-conserving investments, and third, paying close attention to the rural energy problems and the long-term livelihood sources of the households with CCFGP. Given the weak asset base and difficulties of livelihood strategies shift, ecological shelter construction in the upper reaches of the Changjiang River will take a long time.展开更多

Nowadays, Vietnam's handicrafts have a foothold in the world market, and are exported over 163 countries and territories (Tuan, 2010). However, the production activities of the handicraft village have a lot of shortcomings, especially the problem of environmental pollution (Chi, 2010). Therefore, government policy plays a very important role to minimize environmental pollution villages, contributing to improving environmental quality and public health. This paper focuses on: 1). Current status of state policy environment in handicraft villages shows the achievements and limitations of the policy, from which reviews state policy in environments in handicraft villages (through fieldwork in the handicraft villages); and 2). Solution to improve state policy on environmental protection in handicraft villages in Vietnam.展开更多

It is going to be set by both countries with a common boundary for promoting the economic co-operation between two sides. It can be firstly set along the boundary between China and Vietnam. It will promote the economic co-operation between them, but China and ASEAN. It can be set along the Chinese boundary with the neighboring countries and will promote the economic co-operation between the both sides for setting up a better environment around China.展开更多

Through the case study on 11 sample villages generated by the random stratified sampling in Henan Province, authors of this paper find that the distribution of destinations is dispersed in a large area while concentrated in certain places. Most of the destinations are in counties and outside Henan Province. Migrant workers are mainly concentrated in the economically more developed eastern provinces. The central, though a big source of migrant workers, has not formed a core employment area for migrant workers. The main factors influencing migrant workers' choice of employment distances include age, family size, per capita arable land, the village's economic development level, the village terrain, transportation, its distance from the nearest city, and workers' relationship networks. From the perspective of employment destinations, on a provincial scale, the employment attraction coefficient based on the destination's level of economic development and the employment distance, efficiently explains farmers' choice of destinations, that is, destinations with a more developed economy and a shorter employment distance are the top choice for migrant workers.展开更多

The EU Common Agricultural Policy defines agriculture as "multifunctional" and among the different roles and functions expected, there is also the "social function", defined as the ability that the farm has to generate services with respect to a population with risk of social exclusion. This paper investigated all the agricultural initiatives with social impacts that were carried in the lands confiscated from the organized crime (called mafia), mainly in the South of Italy and especially in Sicily. Through an Italian law, these lands could be used with social purposes by a particular kind of associations which might exercise an agricultural activity with the aim to produce food products, sell them in the market and offer employment opportunities in the agricultural sector. In particular, in Sicily, the activity of the "Social Cooperative Placido Rizzotto-Libera Terra" and its winery "Cantina Centopassi" which received honors and awards tbr its production of wine obtained from the earliest harvests and for its social work in that territory were well known. This work, which was part of a much broader study on "wine and legality", aimed to know the opinion of Sicilian wine consumers and their knowledge about this topic with particular reference to the Cantina Centopassi.展开更多

EFAs comprise structured, science-based approaches to determine how much water must be left in the river to protect the aquatic ecosystems and achieve the desired ecological state, The building block methodology (BBM) that was used in this study is designed to identify a series of important flows (the building blocks) which will together provide the essential aspects of the natural hydrological regime that ensure the persistence of as much of the biodiversity as possible. The results show that a total inflow into eastern wetland of 5.52-6.81 m^3/s is required in order to sustain an outflow of 1-2 m^3/s past Ng'iriama and hence meet the "minimum" recommended flow rates further downstream at BBM1 and BBM2 during the drought low flow conditions. The rationale being that a satisfactory flow during drought low flow conditions will guarantee sufficient flows during low flow periods in normal and wet years. The low flows of 2.5 m^3/s and 19 m^3/s are recommended for the driest and wettest months, respectively.展开更多
