Resilience of various innovative water management practices: The case of rice production in the Vietnamese Mekong Delta floodplains

The floodplains play an important role in agricultural development and rural livelihoods in the Vietnamese Mekong Delta. As an intensive rice production area of Vietnam, the floodplain has experienced significant changes in water management regime during the recent decades. Depending on specific locations and irrigation infrastructure investments, four main water management practices have been innovated, particularly a planting season of two crops per year (2C1Y), three crops per year (3C1Y), three years eight crops (3Y8C) and two years five crops (2Y5C). The 4R framework (Reform, Result, Resilience, and Return) was developed based on grounded theory approach for resilience assessment of various innovative water management practices. In terms of resilience, we found that each crop pattern involves pros and cons, and the intensive crop practices are less resilient systems, especially in social, environmental, and ecological aspects. The findings provide good lessons learned not only for Vietnam but also for the other rice-producing deltas implementing ecosystem resilience to adapt to global challenges such as flood, drought, and salinity intrusion.

Understanding farm-level differences in environmental impact and eco-efficiency: The case of rice production in Iran

Eco-efficiency, defined as the economic profit per unit of environmental impact, can largely differ between farms that produce the same crop. Understanding the underlying drivers of differences in eco-efficiency can help to identify effective options for increasing environmental product performance. Here, we analyzed differences in eco-efficiency between 200 paddy farms in Iran. With multiple linear regression modeling, we assessed the influences of farming system (conventional, limited input, organic) and yield, including potential interactions, on economic profit per unit of impact on ecosystems (terrestrial, freshwater, marine) and human health. Our results showed that the eco-efficiency of organic farming systems is (i) positively associated with yield, and (ii) systematically higher compared to conventional and limited input farming systems. We also found that the eco-efficiency of conventional and limited input systems is positively associated with yield for impacts on terrestrial ecosystems, but not for impacts on freshwater and marine ecosystems and human health. Our results reflect both higher economic profits and lower environmental impacts of organic paddy farms per unit of rice production compared to the other two production systems.

Project-Based State Intervention and Agrarian Change in Contemporary China: The Case of Rice Production in Pingwan County, Hunan

This article analyzes the role of the state in the development of capitalist agriculture in contemporary China by focusing on the implementation of the central-government-sponsored National Grain Security Project and Agricultural Industrialization Project in Pingwan county of Hunan province since 2009. It demonstrates that by providing significant (formal and informal) subsidies and transferring large tracts of farmland to large farmers and agribusinesses, the Chinese government has made the capitalist transformation of rice production possible. We stress that in the absence of private property rights, the local governments’ strong control over farmland transactions makes it relatively easy to transfer large tracts quickly, helping agribusinesses and large farmers avoid significant transaction costs they would otherwise have to face under a system of private landownership. The article also shows that existing policies support the transfer of farmland in regions with favorable geographic and climatic conditions over other regions and therefore lack the capacity to significantly decrease regional inequalities.

The right place to grow rice for the Japanese market: comparative analysis of greenhouse gas emissions of rice cultivation in Japan and the United States

ABSTRACTOne consequence of increasing agricultural trade is a shift of geographic location of agricultural activity to more economically productive countries. Whether or not the economic efficiency translates to environmental efficiency for agricultural goods is an open question. To examine environmental implications of shifting agricultural location, we analysed the life-cycle greenhouse gas (GHG) emissions of rice production in Japan and the US for the Japanese market in a comparative manner. This paper presents the life-cycle assessment of brown japonica rice. Our computation of GHG emissions of rice production in Japan and the US were 3.54 and 2.99 kgCO2-eq kg-rice−1, respectively. With respect to harvested area, the emissions were 18.4 in Japan and 27.8 tCO2-eq ha−1 in the US. For Japan to be environmentally competitive with the US production, fundamental restructuration of field size is necessary to increase yield. In conclusion, economic efficiency does not translate to environmental efficiency with the case of rice production. Importing rice is both economically and environmentally viable option for the Japanese market.

Gender differentials in farming efficiency and profits: The case of rice production in the Philippines

Women make essential contributions to the agricultural and rural economies in all developing countries. Rural women are involved in a variety of production and farm management activities. In the Philippines women engage more intensively in agricultural work than men. However, Filipino women’s actual contribution to food production and the rural economy remains undervalued, if not invisible. Using the average treatment effect and farm-level data from the Philippines, this study investigates the effect of gender on farming efficiency, profits, and costs of rice production. Results indicate that female-headed farm households, despite having limited access to land, have higher values of rice production than their male counterparts. However, female-headed households have higher fixed, seed and labor input costs, consequently earning lower profits. In addition, female-headed farm households have lower irrigation costs. Findings from this study also indicate that women are less efficient in farming, but are more likely to adopt improved seed varieties.

Support vector machine-based open crop model (SBOCM): Case of rice production in China.

Existing crop models produce unsatisfactory simulation results and are operationally complicated. The present study, however, demonstrated the unique advantages of statistical crop models for large-scale simulation. Using rice as the research crop, a support vector machine-based open crop model (SBOCM) was developed by integrating developmental stage and yield prediction models. Basic geographical information obtained by surface weather observation stations in China and the 1:1000000 soil database published by the Chinese Academy of Sciences were used. Based on the principle of scale compatibility of modeling data, an open reading frame was designed for the dynamic daily input of meteorological data and output of rice development and yield records. This was used to generate rice developmental stage and yield prediction models, which were integrated into the SBOCM system. The parameters, methods, error resources, and other factors were analyzed. Although not a crop physiology simulation model, the proposed SBOCM can be used for perennial simulation and one-year rice predictions within certain scale ranges. It is convenient for data acquisition, regionally applicable, parametrically simple, and effective for multi-scale factor integration. It has the potential for future integration with extensive social and economic factors to improve the prediction accuracy and practicability.

The efficiency of composite weather index insurance in hedging rice yield risk: evidence from China

AbstractAs an economic and market‐transparent program, weather index insurance is expected to mitigate asymmetric problem. Capturing the relationship between yield and weather factor(s) is the basis of index insurance, but remains a challenge for weather index schemes. Meanwhile, composite weather index insurance is needed by farmers when their agricultural activities involve several risks, but is rarely studied. We aim to design a composite weather index insurance model and evaluate its efficiency in hedging yield risk by using the case of rice production in China. We divide the whole growth cycle of rice into six stages on the basis of agronomic knowledge, and use the average value of each weather factor in each stage to design a weather index. Then, the efficiency of composite weather index insurance is evaluated by mean‐semivariance and value‐at‐risk methods. First, we find that subdivision of the growth cycle helps to better capture the subtle relationship between rice yield and weather factors. Second, composite weather index insurance evidently reduces yield risk. Our findings help further adoption of weather index insurance in agricultural fields.

Technological change, technical and allocative efficiency in Chinese agriculture: the case of rice production in Jiangsu

This paper develops a frontier shadow cost function approach to estimate empirically the effects of technological change, technical and allocative efficiency improvement in Chinese agriculture during the reform period (1980–93). The results reveal that the first phase rural reforms (1979–84) which focused on the decentralization of the production system have had significant impact on technical efficiency but not allocative efficiency. However, during the second phase reforms which was supposed to focus on the liberalization of rural markets, technical efficiency improved very little and allocative efficiency has increased only slightly.

In contrast, the rate of technological change continued to increase, although at a declining rate during the second phase reform.

Determinants of Production Efficiency: The Case of Rice Production in Antique Province, Philippines

Analyses of the efficient use of technologies in the context of irrigated agriculture have been numerous in the literature. On the other hand, empirical studies on rainfed agriculture which is an important source of production and employment generation in many developing countries are scanty. The objective of this paper is to examine how effectively farmers in the rainfed areas in the Philippines, given the current modern technology, apply the technology at the farm level and to identify the factors causing differences in efficiency amongst farmers.

Decomposition Analysis of Derived Demand for Factor Inputs: The Case of Rice Production in Japan

AbstractThe process of the growth of rice production in Japan is analyzed by decomposition analysis of factor input demand. The variation in factor input demand is broken down into three components: output level, factor substitution along an isoquant, and technical change. The analysis is carried out using the estimates of Allen partial elasticities of substitution calculated from the fitted transcendental logarithmic cost function. The decline in labor input level is found to be due mainly to technical change, and the labor‐saving effect of the factor substitution along an isoquant is relatively small.
