An agronomic crop growth model-the Decision Support System for Agro-Technology Transfer-and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase producers' certainty-equivalent revenue. Second, changes in water pricing policy would have a limited impact on the amount of water used. And third, across levels of risk preference, the precipitation contracts are not effective in increasing certainty-equivalent revenue or reducing cumulative water use.

The impact of short video platforms on the sale of agricultural products provides a basis for a scientific study on the relationship between farmers and consumers. Through content analysis and a questionnaire survey, the study analyses the new interactive relationship between agricultural products sold directly by farmers and e-commerce consumers, focusing on the TikTok platform. It considers the development of live streaming and its intrinsic value in the promotion of agricultural products and poverty alleviation in the short video era. Through analysis, it finds that the relationship between producers and consumers is closer and farmers participation in the live broadcast industry largely increases the sales of agricultural products. These further narrow the gap between urban and rural areas and contribute to the realization of common prosperity in China.
