Possible Impacts of Climate Change on Agricultural Production in China and Its Adaptation Countermeasures

Global climate warming has discernable impacts on various natural systems and biological systems. As the most fragile ecosystem,agriculture is subjected to the most direct impacts from climate change. Of these impacts,the first one is the change in agricultural climate resources,which directly affects agricultural cultivation structure and crop variety distribution and finally results in the change in crop yield. Here,we review the advances in the impacts of climate change on crop yield,agricultural climate resources and China＇s agricultural cropping system and crop variety distribution pattern,and prospect the countermeasures for agricultural production in order to meet the future climate change,and several issues must be given high priority.

Assessment of Climate for Agricultural Suitability and Optimal Allocation of Agricultural Production in the Guanzhong Region, Shaanxi Province

Based on spatial climatic data of agriculture and the experiment data, the models of agro-ecological assessment of climate for agricultural suitability in this study were developed using the fuzzy mathematical method. Three coefficients, in- cluding the resource coefficient （Cr）, the efficiency coefficient （Ce）, and the utility co- efficient （K）, were used in the models, which were calculated based on temperature, moisture, and sunshine duration data of Guanzhong region, Shaanxi Province. The results indicated that resource coefficient was higher in west of the region than that in east, and higher in south （especially in the Central Shaanxi Plain） than that in the Weibei plateau. The value of Cr changed from 6.5 to 9.2 from north to plain area. Spatial change of efficiency coefficient was obvious, lower in the northeast than in the central plain, and the value of Ce changed from 2.3 to 6.5 from the northeast to the central plain. As for utility coefficient, it was lower in northeastern part of the Weibei plateau and in southern mountain areas than that in the central plain, showing significant latitudinal zonality. Furthermore, the value of K increased from 0.35 to 0.78 from northeast to the central plain, and decreased from 0.78 to 0.53 from the central plain to southern mountain areas. These indicated that climate resource in the central plain region was more abundant and potential, compared with other regions. GuanZhong region was classified into three larger agricultural zones and three small independent zones, according to agro-ecological assessment. Light, heat and water resources should be made use of in an efficient way in spatial allo- cation of agricultural production. For example, water facilities should also be im- proved in Weibei plateau region where highly-qualified fruit should be enhanced and fruit processing industrial chain should be shaped. Large-scale production area of wheat should be increased in central irrigation region and more vegetable bases should be developed around large and medium-scale cities. Thanks for outstanding water conservation function, the three-dimensional agriculture including medicine and other sideline production should be developed in Qinling Mountains and the special- ized commercial agriculture should be accelerated in independent small zones, ac- cording to local conditions. In the research, different crop varieties were developed in corresponding regions as per current eco-climatic conditions.

Flora, life form characteristics, and plan for the promotion of biodiversity in South Korea＇s Globally Important Agricultural Heritage System, the traditional Gudeuljang irrigated rice terraces in Cheongsando

The objectives of this study were to analyze the biodiversity of the Traditional Gudeuljang Irrigated Rice Terraces in Cheongsando, South Korea's representative GIAHS(Globally Important Agricultural Heritage System) site, with reference to position and land-use features, and to develop a plan to promote agricultural biodiversity in the region. We confirmed approximately 54,000 m2 of Gudeuljang paddy fields by an on-site survey. Of the Traditional Gudeuljang Irrigated Rice Terraces confirmed by onsite inspection, our survey showed that approximately 24,000 m2 are currently being used as paddy fields, approximately 15,000 m2 are being used as dry fields, and approximately 14,000 m2 are fallow. In terms of other non-agricultural land use, there was grassland, including graveyards; artificial arboreal land, such as orchards, rivers and wetlands, and man-made facilities, such as roads and residences. We also confirmed that the Traditional Gudeuljang Irrigated Rice Terraces had higher plant species diversity than conventional terraced rice paddies, and there was a difference in life form characteristics between the two types. Although the superficial topsoil structure is thesame for the Traditional Gudeuljang Irrigated Rice Terraces(TGIRTs) and conventional terraced rice paddies, it is thought that the differences in the subsurface structure of the TGIRTs contribute greatly to species and habitat diversity. However, the TGIRTs in Cheongsando are facing degeneration, due to damage and reduction in agricultural activity. The main cause is the reduction in the number of farming households due to an aging population in Cheongsando. In order to address this problem, we proposed a management plan, related to fallow paddy fields in South Korea, to initiate voluntary activities in the TGIRTs.

Spatial-temporal Evolution Pattern of Agricultural Productivity in Northwestern Sichuan Plateau

Currently, the agricultural growth in developed countries mainly relies on the improvement of productivity, which is also the target for China. Accordingly, the purpose of this study was to describe the spatial-temporal evolution pattern of agricultural productivity, to reveal changes in total factor productivity in 2ooo-2olo, and analyze the impact of these changes in northwestern Sichuan plateau, China. Using data envelopment analysis （DEA） and the Malmquist Index, an in-depth study was conducted on agricultural productivity and changes in total factor productivity of 31 counties in northwestern Sichuan plateau. Results indicated that： （1） geographically, counties with optimal efficiency were mainly located in the north of northwestern Sichuan plateau and those with the lowest efficiency, in the south; （2） relative to pure technical efficiency, scale efficiency was the dominant factor in determining agricultural productivity; （3） the redundancy rate of input factors in zolo was slightly lower than that in zooo, thereby indicating an improved utilization of input factors to a certain extent and a great potential for further improving such utilization; （4） during the 2ooo-2olo period, the agricultural total factor productivity had an average annual growth rate of 8.3%, but the growth rates in various regions differed widely; （5） technical progress was the dominant factor promoting the improvement of total factor oroductivitv inagriculture. The disparities in spatial distribution may be due to the differences of natural conditions, former level agricultural productivity between counties. The findings are valuable for the government to make sustainable development policies for agriculture and improving agricultural development in northwestern Sichuan plateau.

Impacts of Agricultural Mechanization on Agricultural Production in Guangdong Province

Agricultural machinery represents modern method and modern condition of production, and Agricultural mechanization is the key basis and symbol of modern agriculture. Based on analyses of agricultural mechanization development in Guangdong Province from 1988 to 2008, production function was developed to estimate the effects of agricultural mechanization on agricultural production. The results indicated that the contribution of agricultural mechanization to production continues to increase. The agricultural mechanization increased by 1%, and grain production by0.35%. Therefore, government should encourage development of agricultural mechanization in order to improve agricultural production in Guangdong Province.

Traditional farming in the mountainous region of Bangladesh and its modifications

Shifting cultivation is a traditional farming system practiced in the tropical mountainous areas. Although it has been widely perceived as an economically inefficient and environmentally harmful agricultural production system, recent science reviews, however, indicate that the deleterious impacts of shifting cultivation on environment may have been overestimated. Despite the pressures of agricultural intensification in areas where shifting cultivation occurs, farmers across the tropics still maintain this traditional farming system. The objective of this study was to explore existing traditional shifting cultivation practices and their various modifications including the innovative farming techniques developed by farmers in the Chittagong Hill Tracts(CHTs), the mountainous region of Bangladesh, and examine their importance with respect to recent socio-economic and environmental changes. The study revealed that shifting cultivation still exists as the most dominant farming method which supports livelihoods and culture of the hill ethnic people. However, demand for more food and household income to meet livelihood needs of an increasing population combined with a rapid deterioration of soil and water quality over decades contributed to development of innovative farming practices through fallow land farming, crop substitution, agroforestry and homestead gardening in the CHTs. Through these farming techniques farmers maintain a strong relationship with traditional knowledge system embedded in the ageold shifting cultivation practices. Today state policies and market forces act in favor of replacement of traditional farming with intensive cash crop agriculture. It seems that disappearance of traditional farming practices from the hills may threaten local biodiversity and food security. It may be recommended that shifting cultivation should be encouraged in areas where they have potential for contributing to preservation of native biodiversity and ecosystem services, and protection of local peoples' food security and cultural identity.

Impact of Climatic Change on Agricultural Production and Response Strategies in China

A number of studies indicate that global climate warming has been increasing, especially in recent decades. Climate warming greatly affects global agro-production and food security-- becoming a hotspot of global environmental change. This paper proposes a structural and orientational framework for scientifically addressing climatic change impact on agroroduction. Through literature reviews and comparative studies, the paper systematically summarizes influencing mechanisms and impact of climate warming on such agro-production factors as light, temperature, soil quality and water environment. The impact of climate warm- ing on cultivation regions, cropping systems, crop pests, agro- production capacity, agro-economy and farm management is analyzed. Then, suitable climate-adapting agro-development strategies are put forward for different regions in China. The strategies are carefully selected from a repository of international tested climatic change countermeasures in agriculture at national or district level.

Environmental Impact of Climate Change on Agricultural Production in Ekiti State, Nigeria

Climate change will impact agriculture and food production around the world due to the effects of elevated CO2 in the atmosphere, higher temperature, altered precipitation and transpiration regimes, increased frequency of extreme events, and modified weed, pest and pathogen pressure. Data of this study were collected from primary and secondary sources. Primary sources of data were collected using two sets of structured questionnaires. A total number of three hundred （300） questionnaires were administered on categories of respondents in this study. Results of this study revealed that food crops are the major crops cultivated in the study area, and the effects of climate change on agricultural production results in soil loss, plant nutrient loss, textural change, increase in pest and diseases and poor yield germination etc.. This study therefore recommended that cover trees should be planted, which will provide shade and reduce heat, due to climate change and the preservation of underground water.

Improvement of Cellulose Hydrolysis Process and Cost Savings

The hydrolysis process to obtain the so-called ＂reducing sugars＂ represents the main step involved in the production of the second generation bioethanol. This product can be obtained directly from various types of green biomass, replacing the use of cereals cultivations, with obvious benefits to the environment and the economy of agricultural production. However, it is necessary to improve the hydrolysis process of the cellulose to achieve this goal. To this purpose, we applied a chemical process formerly used. The values of sugars yield were increased by about 40% with respect to the previous study. Further significant cost savings were accomplished, resulting from the recovery of the by-product, calcium sulfate, commercially known as gypsum.

Thought on the Implementation of Agricultural Standardization in the Grain Production and Modern Agriculture

The construction of Grain Production Functional Zone and Modern Agicultural Zone （Two Zones for short） plays a key role in the development of modern agriculture and solving the quantity and quality problems of agricultural products. The Two Zones serves as the important form and carrier of agricultural standardization and the agricultural standardization provides means and ways for it. The paper puts forward the suggestions and solutions for agricultural standardization in Two Zones in the aspects of boosting standards innovation projects, management and so forth.

Research on Application of information technology in agricultural economic management

In the current social, agricultural development is heavily influenced by the level of agricultural information development, so, it is necessary to pay attention to the development of information technology in order to maintain a sustained, steady and rapid development of agriculture, as well as we use information technology in all aspects of agricultural production, so as to make more rapid and stable development of Chinese agriculture. In Agricultural Economics and Management should focus on the help of information technology. The main author makes a brief analysis on the role of information technology in the agricultural economy and the management of specific applications, which is designed to promote the further development of Chinese agriculture.

Pesticide Packaging Waste Management Model for Thailand

Pesticide packaging waste in Thailand has recently been valued as a kind of commercial product. Selling empty pesticide packaging to reuse/recycling business has been increased in all over the country. Subject to the resource conservation and global climate change, this could be defined as sustainable or green consumption for the most beneficial use of natural resources. However, on the point of environmental and public health, this is the way to disperse harmfulness of pesticide into non-target areas. Human and environmental health risk of exposure due to pesticide residue in such packaging waste could be a co-incident. This paper was aimed to determine a practical model for pesticide packaging waste management appropriate for Thailand based on the context of country＇s circumstances and the best practices reported around the world. Establishing some necessary components has been proposed, i.e. multiple rinse method applied by farmers conscientiously, central collecting site driven by local community, waste recovery program offered by pesticide production enterprises, and sanitary glass bottle washing plant registration and regulations launched by the government. In conclusion, governmental initiative and all stakeholders including in pesticide packaging waste supply chain should be encouraged to contribute their participation towards sustainable management.
