However, the current rural community self-organizing construction falls far behind the requirements of realistic practice all over China, which greatly affects the advancement of the rural modernization of China. On the other hand, social work provides a unique perspective and method to deal with these problems. Its service philosophy of selfservice as well as its humanitarian value and practical working methods provide reality conformity for the intervention into rural community self-organizing, making it conductive to improving the social relations between rural community residents and possible to realize the mutual development of rural community and rural community residents.展开更多

Secondly is to point out the key concepts of the theory of entrepreneur and the strength of it to assist the community development, to teach young people, adults and cooperatives members to prepare them to pertain good entrepreneurship that meets cooperatives concepts and principles. Thirdly is to give an example of research study that describes how to identify entrepreneurial capability of agricultural cooperatives members in Thailand, dependent variable is qualitative or binary, we use "odds value" or probability of success over the probability of failure to identify the set of odds value, and use exponential function to transform the odds value to be the log of odds or Logit model. If probability of entrepreneur is over the cutting point of 0.8, it implied that members are pertained high entrepreneurial capability and vise versa. The first step of research is the analysis of five year panel secondary data during 2011-2015, collected from Cooperatives Auditing Department. Eight groups of 679 numbers of data from 215 cooperatives were calculated, data were divided by the number of member. These eight independent variables are Total income per member, Total equity per member, Net profit per member, Co-ops operating capital per member, Total cooperatives capital per member, Total deposit per member, Total asset per member, Number of member. Qualitative data are the four sizes of cooperatives: large, big, medium, and small. Qualitative data are the only one intervening variable in the model. Secondary data found that only four quantitative independent variables effect to entrepreneurial capability. Total asset per member, and Total income per member had negative effect, but Net profit per member, and Cooperatives capital per member had positive effect. It means that if cooperatives acquire more and more asset, cooperatives will have more burden of debt or equity and probability of entrepreneur will be decreased. If cooperatives gain more and more income to the firm, it means the complex organization or the cooperatives will success but the individual member who is individual finn will get loss. Cooperatives capital per member and Net profit per member have positive effect. Because cooperatives capital were gained from residual and after the allocation of cooperatives surplus to be patronage refund according to the volume of business which member had done with the cooperatives and dividend pay out to member according to the number of stocks they held for their saving with the cooperatives. For qualitative variable, large and medium size of cooperatives had no any effects, but small size of cooperatives had more effect than the big size. It implied that big cooperatives who had more and more number of members have more and more burden. Small size of cooperatives is similar to individual firm of each member. Thus, optimum size of cooperatives is suitable for their service and efficient management, if the size of business volume increasing continuously, the quality of service will decrease, because almost cooperatives organization is pricing at break even point. Second step is a primary survey of data from Rayong province. Seventy-five samples of cooperatives members have not recorded their business information, both revenue and cost. We cannot use logistic regression to run the second model, but only Multiple Regression Analysis (MRA). MRA results identify that the cooperatives profit of each member depends on three variables: (1) sales, (2) member responsibility (not board member responsibility or Management responsibility), (3) member's level of education. Suggestion and recommendation is that agricultural cooperatives members in Thailand still have to improve their entrepreneurial capability by recording all information related to business functions and prepare financial record to represent efficient use of resources to meet member and community's needs.展开更多

However, the existing literature has paid little attention to it. Considering the cooperation patents, published in the agriculture field stemming from the Full-text Database of China Patents as the study object, the spatial and institutional attribute of the authors as the data source, and by combining the social network and spatial econometrics analysis, this paper analyzes the structure evolution characteristics of cooperative innovation networks of agricultural government-industry-university-research institute in the city level of China in 1985–2014, based on the triple helix theory, with the influence factors discussed. This shows that, 1) since 1985, China's agricultural innovation level has been substantially increased, but the development degree of the cooperative innovation network is low, and the patent cooperation mainly relies on authors in the same unit; 2) enterprises play a leading role in the agricultural cooperative innovation. The effect of the government and hybrid organizations driven by the government is not obvious; 3) the cooperative innovation in the province and city dominates, and a multi-pole pattern has been formed. The cooperative innovation network structure evolves from a single helix empty core and double helix multi core to a double helix hierarchical network; 4) the city's science, education funding and personnel investment are key factors determining the agricultural cooperative innovation, while the agricultural development of the city presents slight negative impacts on it. The spatial mismatch of supply and demand is present in the technical cooperative innovation of China's agriculture. Therefore, the science enhancement and education investment to big agricultural provinces should be promptly implemented.展开更多

The impacts of natural conditions, target, and demand elements on public goods investment are analyzed with statistical method, and the determinants of public goods investment in the areas are obtained by using population-weighted and stepwise regression models with Eviews6.0 software with survey data in 2008 and calculated data based on GIS of 20 typical villages in mountainous regions in Sichuan, China. The results showed:(1) natural conditions are the important determinants of public investment. Mountainous villages with steep slope have relatively high levels of investment;(2) concentration of population and the educational levels of the village leaders also have important impacts on public goods investment;(3) the government is more concerned with public investment resources particularly in areas characterized by fragile ecological environment and poor agricultural output. These results suggest that the current investment strategy helps to reduce disparities in regional development.展开更多

With a per capita possession of about 0.08 ha of cropland, Chinese farmers in rural areas adopt various ways in response to these changes in a bit to maintain their livelihood, wherein the agricultural system is facing one more options possible. To understand how rural communities have used different mechanisms to adapt to the economic and natural changes, we joined a survey in dry valleys of the Min upriver area under Maoxian county of western Sichuan province, southwestern China and visited the local people. Changes in the main crop cultivation have shown up an important means to keep up their household income. Farm households start seeking economic growth through diversified cultivating of cereal and economic crops in five lines, namely cereal, apple monoculture, apple and vegetables, plum and vegetables, mixed fruits and vegetables. These new lines mirror farmers' flexibility to cope with today's economic-social and climatic changes. The farming operation has changed all the more from a subsistence on grain to special agricultural products. Economic reforms in the early 1980 s motivated theprogress first in conversion of production from grain to fruits, and the desire to increase family income turned out to be an impetus for the subsequent events. At present, more farmers moving out of the rural areas, uneasy availability of labor force, increased opportunity cost of labors and their wages, increased farm size, and the urgent demand for the agricultural labor force, all these combine into the trend of the agricultural system of China on facing further economic-social reforms and reconstruction of the countryside across China.展开更多

In the research, carbon emission in community is a kind of ecological resources and negative externality is the cause of increase of rural carbon emission. Compared with governmental ruling and marketing approach, community manage- ment mode proves more effective to solve the problem of negative externality of carbon emission in community. Furthermore, rural carbon, emission was analyzed in detail on basis of community management mode and extending mode of carbon emis- sion in rural areas. In addition, some policies and suggestions were proposed to im- prove community management of carbon emission in rural areas, providing an ef- fective way for low-carbon economy in rural areas.展开更多

On the other hand, the introduced "improved cooking stoves" also have their own disadvantages. Therefore, the case study was conducted aiming to study the rationale of using traditional stoves and document the innovative biomass energy saving practices of the community. The research studied two pilot areas in rural community with different agro-ecology and farming systems. Moreover, individual and focus group discussions were conducted among women households using transect and random sampling. The f'mdings indicate that use of traditional stoves is dominant practice due to flexibility, simplicity and multi-functionality. Moreover, the biomass fuel use is integral part of the fanning system, socio-cultural framework and habits and customs of local community. The study has documented local innovation practices of biomass energy saving by improving stoves and chimney, combining different crops in food cooking, improving local beer processing, shifting crop-land to woodland. Moreover, the study reveals that the enclosure of communal forests due to the modem extension services is attributed with long distance travel to collect fuel wood, leading to conflicts and declines livelihood diversity of the poor population. Hence, consideration of local initiatives in development of appropriate and sustainable technology is essential.展开更多

Mountains around the world including northern and north western belts of Pakistan are highly sensitive to deforestation and other LULC changes, which have profound impacts on various sectors of bio-physical and socio-economic systems. Assessment of LULC changes has high significance for protection, conservation and monitoring mountainous environment. The present study is an attempt to assess the landscape changes with particular reference to forest cover depletion in Kurram Agency located in the north western mountain belt of Pakistan. For detailed comparative analysis the study area has been divided into three sections, which coincide with the present administrative divisions of the Agency, i.e., Upper,Lower and Central Kurram. Temporal span of this study covers four decades. In this study, land use map of 1970 and land sat satellite imageries of 1987, 2000 and 2014 were used as spatial data sets. The images were processed and classified into six LULC classes through geospatial packages and change detection maps were prepared for each division and time period.Findings of the study reveal two trends in the four major LULC categories. Forest and rangeland have shrunk, on average, by 15% and 7.5% respectively while, bare soil and rocks outcrops have expanded by 89% and agriculture land by 7.2% in Kurram agency.The water bodies and snow cover have minor fluctuation in its land area. Major causes of shrinking greenery is attributed to high influx of Afghan refugees and high energy demand of growing population. However, with outflow of the refugees from Kurram agency the general trend in forest cover has reverted and deforestation rate has slowed down.展开更多

However, people who try to manage these challenges use "text type" in books and through other communication media (publications), but the effect has scarcely been effective because, most of the people living in rural communities are illiterates. The purpose of this study was to use pictorial illustrations to create awareness on how socioeconomic development affects rural communities (Cape Three Points) and the extent to which its effect can be seen on human life within the local communities (fishermen, farmers, and fish mongers) in terms of their livelihood, attitudes, education and on the general environment. Interviews were mainly used to ascertain facts on how the situation was before the new developments started. Workshops were also organized for focus groups, through which the effect of pictorial illustrations on the people were ascertained. Again, how they should prepare for the foreseen changes that will emanate from any form of rural development was also discussed. At the end of the study, it came to light that many of our rural areas face significant challenges. These challenges as a matter of fact affect their cultural practices and the socio-economic development of the people in such rural communities and the country as a whole. It is believed that these challenges and many other related concerns that have emanated from this study would be critically recognized and managed if not solved by the powers that be. Results from this study will form a basis for further discussion of socio-economic effects of rural development on rural communities and any other related effects caused by any physical change on rural environment.展开更多

Moreover, the study reveals that the enclosure of communal forests due to the modem extension services is attributed with long distance travel to collect fuel wood, leading to conflicts and declines livelihood diversity of the poor population. Hence, consideration of local initiatives in development of appropriate and sustainable technology is essential.
文摘Deforestation and other Land Use and Land Cover(LULC) changes, driven by variety of physical and anthropogenic factors, have altered the mountainous environment. Mountains around the world including northern and north western belts of Pakistan are highly sensitive to deforestation and other LULC changes, which have profound impacts on various sectors of bio-physical and socio-economic systems. Assessment of LULC changes has high significance for protection, conservation and monitoring mountainous environment. The present study is an attempt to assess the landscape changes with particular reference to forest cover depletion in Kurram Agency located in the north western mountain belt of Pakistan. For detailed comparative analysis the study area has been divided into three sections, which coincide with the present administrative divisions of the Agency, i.e., Upper,Lower and Central Kurram. Temporal span of this study covers four decades. In this study, land use map of 1970 and land sat satellite imageries of 1987, 2000 and 2014 were used as spatial data sets. The images were processed and classified into six LULC classes through geospatial packages and change detection maps were prepared for each division and time period.Findings of the study reveal two trends in the four major LULC categories. Forest and rangeland have shrunk, on average, by 15% and 7.5% respectively while, bare soil and rocks outcrops have expanded by 89% and agriculture land by 7.2% in Kurram agency.The water bodies and snow cover have minor fluctuation in its land area. Major causes of shrinking greenery is attributed to high influx of Afghan refugees and high energy demand of growing population. However, with outflow of the refugees from Kurram agency the general trend in forest cover has reverted and deforestation rate has slowed down.
文摘It has come to notice that developments that take place in rural communities bring about a lot of challenges both positive and negative. However, people who try to manage these challenges use "text type" in books and through other communication media (publications), but the effect has scarcely been effective because, most of the people living in rural communities are illiterates. The purpose of this study was to use pictorial illustrations to create awareness on how socioeconomic development affects rural communities (Cape Three Points) and the extent to which its effect can be seen on human life within the local communities (fishermen, farmers, and fish mongers) in terms of their livelihood, attitudes, education and on the general environment. Interviews were mainly used to ascertain facts on how the situation was before the new developments started. Workshops were also organized for focus groups, through which the effect of pictorial illustrations on the people were ascertained. Again, how they should prepare for the foreseen changes that will emanate from any form of rural development was also discussed. At the end of the study, it came to light that many of our rural areas face significant challenges. These challenges as a matter of fact affect their cultural practices and the socio-economic development of the people in such rural communities and the country as a whole. It is believed that these challenges and many other related concerns that have emanated from this study would be critically recognized and managed if not solved by the powers that be. Results from this study will form a basis for further discussion of socio-economic effects of rural development on rural communities and any other related effects caused by any physical change on rural environment.
