Spatio-Temporal Agricultural Drought Quantification in a Rainfed Agriculture, Athi-Galana-Sabaki River Basin

This study employs a quantitative approach to comprehensively investigate the full propagation process of agricultural drought, focusing on pigeon peas (the most grown crop in the AGS Basin) planting seasonal variations. The study modelled seasonal variabilities in the seasonal Standardized Precipitation Index (SPI) and Standardized Agricultural Drought Index (SADI). To necessitate comparison, SADI and SPI were Normalized (from −1 to 1) as they had different ranges and hence could not be compared. From the seasonal indices, the pigeon peas planting season (July to September) was singled out as the most important season to study agricultural droughts. The planting season analysis selected all years with severe conditions (2008, 2009, 2010, 2011, 2017 and 2022) for spatial analysis. Spatial analysis revealed that most areas in the upstream part of the Basin and Coastal region in the lowlands experienced severe to extreme agricultural droughts in highlighted drought years. The modelled agricultural drought results were validated using yield data from two stations in the Basin. The results show that the model performed well with a Pearson Coefficient of 0.87 and a Root Mean Square Error of 0.29. This proactive approach aims to ensure food security, especially in scenarios where the Basin anticipates significantly reduced precipitation affecting water available for agriculture, enabling policymakers, water resource managers and agricultural sector stakeholders to equitably allocate resources and mitigate the effects of droughts in the most affected areas to significantly reduce the socioeconomic drought that is amplified by agricultural drought in rainfed agriculture river basins.

Study on Consistent Agricultural Compensation Standards for Ecosystem and Ecological Value

Chinese and international studies on agricultural ecological compensation standards fall into two categories:While some focus on the cost of ecological protection,others proceed from the value of ecological services.Cost and value are two aspects of an integrated input-output system,but most existing studies on both types of compensation standards are independent of each other.Drawing upon the reasonable elements from both types of studies to overcome each other’s one-sidedness,this paper has created a“model of consistent compensation standards for the ecosystem and ecological value,”integrating the research approaches for both types of compensation standards under the same analytical framework.Through the application and analysis of this model,this paper has verified the model’s theoretical and practical significance in correcting the one-sidedness of each type of research.The principles and methodologies for creating the model may be further extended to research on agricultural ecological compensation standards under different conditions.In some circumstances,the ability of relatively redundant resources to create ecological value is overlooked.To address this problem,this paper employs a linear programming(LP)sensitivity analysis instrument to correct the model’s initial optimal solutions and arrive at consistent compensation standards that satisfy the consistency between ecosystem and ecological value,thus perfecting the theoretical and methodological system created by this paper for research on agricultural ecological compensation standards.

Technology and Infrastructure Considerations for E-Commerce in Chinese Agriculture

Information technology （IT） was one of the most intensively studied and extensively applied technologies in the 20th century and its research and application will be even more accelerated in the 21st century. The impact of IT is more farreaching than any one may have had imagined, encompassing all facets and sectors of society. Economically, e-commerce generated more than $1.5 trillion in the US in 2004 and is projected to be 30, 15 and 2.6% of the total manufacturing, whole sales and retail sales in the US in 2006 respectively. IT research in agriculture has so far been particularly applied to such fields as precision farming and bioinformatics and in extension and farming practices. As such, its potential application in agricultural e-commerce has only begun to be explored. The United States Department of Agriculture has identified four different functions that e-commerce firms perform in the agricultural sector. They are： （1） information distribution, （2） input supply, （3） commodity trading floor, and （4） logistics/supply chain management. Unlike other industrial products, agricultural products are much more diverse and difficult to process and handle. For instance, fruits and vegetables are perishable and have to reach the market and the hands of consumers within a short period of time. One of the problems for IT applications in agriculture is the lack of standard measures in characteristics and quality of perishable produce and processing foods. Standards are pre-requisites for effective IT application and e-commerce. According to the Global Commerce Initiative, standards bring scalability, portability and affordability to the business process. Standards speed up the supply chain and reduce errors and protect technology investments and ensure system to system interaction and interoperability. Because the complexity of issues involved in standardization, the process of standardization must involve the input and discussion from all segments of the society. Being the largest agricultural country in the world and one of the most active trading partners in the international market, China must also be involved in determining the standards for both domestic and international trades. These measures are the necessary foundations for e-commerce in agriculture. In this paper, we provide a review of the technological development of standardization and coding that are prerequisites for IT application in e-commerce. This understanding is important for professionals in China to promote e- commerce in agriculture. Finally, we propose that a national committee to be formed in China, which includes IT experts from private sectors, academic professionals and governmental officials. This committee should consider the progress being made elsewhere in the world, the unique properties of Chinese commodities and appropriate business models to determine a set of standard measures that are transportable and communicable digitally in the world market for China＇s e- commerce in agriculture.

Performance of different drought indices for agriculture drought in the North China Plain

The Palmer drought severity index （PDSI）, standardized precipitation index （SPI）, and standardized precipitation evapotranspiration index （SPEI） are used worldwide for drought assessment and monitoring. However, substantial differences exist in the performance for agricultural drought among these indices and among regions. Here, we performed statistical assessments to compare the strengths of different drought indices for agricultural drought in the North China Plain. Small differences were detected in the comparative performances of SPI and SPEI that were smaller at the long-term scale than those at the short-term scale. The correlation between SPI/SPEI and PDSI considerably increased from 1- to 12-month lags, and a slight decreasing trend was exhibited during 12- and 24-month lags, indicating a 12-month scale in the PDSI, whereas the SPI was strongly correlated with the SPEI at 1- to 24-month lags. Interestingly, the correlation between the trend of temperature and the mean absolute error and its correlation coefficient both suggested stronger relationships between SPI and the SPEI in areas of rapid climate warming. In addition, the yield-drought correlations tended to be higher for the SPI and SPEI than that for the PDSI at the station scale, whereas small differences were detected between the SPI and SPEI in the performance on agricultural systems. However, large differences in the influence of drought conditions on the yields of winter wheat and summer maize were evident among various indices during the crop-growing season. Our findings suggested that multi-indices in drought monitoring are needed in order to acquire robust conclusions.

Preliminary Study on the Standard of Selenium Content in Agricultural Products

With the improvement of living standards, people pay more attention to the agricultural products with health protection function, and the selenium-rich agricultural products attract more and more consumers. The main biological role of selenium is to resist oxidation and inflammatory response, mainly focusing on resisting aging, preventing cardiovascular disease, protecting eyesight, counteracting or destroying the toxic properties, preventing cancer and thyroid disease. In most areas of China, there is a widespread shortage of selenium, thus producing selenium-rich agricultural products to provide natural selenium-rich health food to the areas in need of selenium, has gradually become a new hot spot of China's health food industry, but high content of selenium in food is detrimental to human body, even leads to selenium intoxication, and artificially adding inorganic selenium is difficult to guarantee that the selenium content of agricultural products is not exceeded. According to human body's daily demand for selenium in dietetics and the content of selenium in agricultural products in the Chinese food composition table, we put forward the recommendations on the standard of selenium in agricultural products, in order to provide the basis for China to formulate the health standard of selenium content in selenium-rich agricultural products.

Calculation of Ecological Compensation Standards for the Kuancheng Traditional Chestnut Cultivation System

Kuancheng Traditional Chestnut Cultivation System is located in the Beijing-Tianjin-Hebei Water Containment Function Area.The Traditional Chestnut Cultivation System is characterized by agroforestry compound,and some studies have shown that the compound planting of chestnut has better ecological benefits than the single chestnut planting mode.However,most of the local farmers in Kuancheng are mainly engaged in single chestnut cultivation.Through ecological compensation,farmers are being encouraged to change their chestnut planting mode,which can achieve the purpose of inheriting China’s important agricultural heritage and improving the ecological benefits.This paper introduces preference coefficients to correct for opportunity costs,and through interviews and questionnaires,we obtained the input and output of the single chestnut cultivation,chestnut-maitake,chestnut-millet,and chestnut-chicken and the income of laborers working outside the home in the Kuancheng area.Through analysis and calculation,we obtained the following results:(1)Although the net income of the three chestnut composite modes is higher,their economic input is higher than that of a single chestnut planting mode,and the return on unit investment is lower.(2)The average income of young and middle-aged workers who work outside is higher than that of the local farming industry,so the local chestnut agroforestry plantation has a higher opportunity cost.(3)The final calculation shows that the chestnut-chicken agroforestry operation mode needs no compensation,the chestnut-maitake plantation mode is compensated at least 1608.5 USD ha^(-1) yr^(-1),and the minimum compensation for the chestnut-millet plantation mode is 198.3 USD ha^(-1) yr^(-1),which can guarantee that farmers receive the full value of their creations.Ultimately,farmers are incentivized to revive the traditional agroforestry production mode to achieve both economic and ecological benefits while inheriting agricultural heritage.

生产标准化与农业规模生产的范围选择

农业规模化经营是我国实现农业现代化的重要途径,而规模化生产过程中雇佣劳动力的监督问题,使得规模化经营者在选择雇佣经营或外包经营时常常陷入两难境地。在监督困境不可避免且当下规模化经营势在必行之时,经营者可以将雇佣劳动力的监督成本视为其经营成本的一部分,通过对比成本创新与质量创新的成本收益,进行农业规模生产的范围选择。在成本-质量创新的双目标任务下,生产单位受农作物标准化生产程度的影响,标准化程度较高时,经营者有成本创新的偏好,其生产呈现出规模效应;反之,经营者更愿意追求质量创新,将生产范围缩小到农户家庭等较小的生产单位中去。
