In spite of the increasing popularity of the Ricardian model for the study of the impact of climate change on agriculture, there has been few attempts to examine the role of interregional spillovers in this framework and all of them rely on geographical proximity-based weighting schemes. We remedy to this gap by focusing on the spatial externalities of surface water flow used for irrigation purposes and demonstrate that farmland value, the usual dependent variable used in the Ricardian framework, is a function of the climate variables experienced locally and in the upstream locations. This novel approach is tested empirically on a spatial panel model estimated across the counties of the Southwest USA over 1997-2012. This region is one of the driest in the country, hence its agriculture relies heavily on irrigated surface water. The results highlight how the weather conditions in upstream counties significantly affect downstream agriculture, thus the actual impact of climate change on agriculture and subsequent adaptation policies cannot overlook the streamflow network anymore.

The purpose of this study is to analyze the learning tendency of rural residents participating in lifelong education. The analysis data were analyzed using a polynomial model for 3,685 people using raw materials from a lifetime education survey. According to the analysis, participants in rural residents prefer small study groups. They were also approached on a practical level, such as life-help or self-realization. And the participating education programs were highly involved in vocational non-formal education. Based on the workings of personal backgrounds, participation of people with lower income and lower educational backgrounds is more active than in urban areas. In addition, the effect of improving the quality of life through lifelong education was shown in the order of big cities, small cities, rural areas. These results suggest that ways to improve the quality of life through lifelong education are not suitable as a means to maintain rural population.
