Narrow Results

Climate change is attracting increasing attention from the international community. To assess the impact of climate change on China’s rice production, this paper re-organizes the main rice-producing areas by adding up the annual production of the provincial level regions between 1979 and 2011, utilizes Cobb–Douglas function using daily weather data over the whole growing season. Our analysis of the panel data shows that minimum temperatures (Tmin), maximum temperatures (Tmax), temperature difference (TD) and precipitation (RP) are the four key climate determinants of rice production in China. Among these, temperature difference is surprisingly significant and all except maximum temperatures have positive effects. However, because the actual minimum temperatures and precipitation in China’s main rice-producing areas declined while the maximum temperatures and the temperature difference increased during our sample period, climate change has actually provided a negative contribution to the increase in China’s rice production.

The study compared the climate indices and considered the major agricultural climate features, including precipitation, temperature, solar duration, radiation, and uncertainty features such as the ENSO and rainfall extremes, to compose the climate indices for rice production in Taiwan. The study used the regression model for panel data random effects, estimated rice-climatic indices for the first and second rice crop yields, and based on the results to provide specific policy recommendations.

This study utilized the contingent valuation method to estimate the value of water-related ecosystem services (ES) in Vietnam, focusing on provisioning and regulating services for addressing water scarcity (WS) in rice farming. By incorporating gender and climate change perceptions, it expanded the existing literature on valuing river ecosystem services. The findings showed a significant number of households experiencing severe water scarcity in the past five years, with over 70% facing occasional or regular WS in the last 12 months. Rice farmers were willing to adopt coping measures and preventive practices to preserve water-related ES, recognizing their importance for sustaining rice cultivation. Farmers demonstrated willingness to contribute financially to restore and maintain water-related ES in rivers and canals. The median willingness to pay for restoration was VND188,300/ha, with estimated values of US$2,898,133 for a 10% affected area and US$23,185,068 for an 80% affected area over five years. Perception of WS severity and associated risk positively influenced households’ decisions to contribute financially. These findings have policy implications and provide insights for effective coping strategies against WS, enhancing water-resilient agriculture in the Lower Mekong Basin.
