The Effect of Urban Agriculture on Water Security: A Spatial Approach

Abstract

This study aimed to examine the influence of agricultural development under urbanization on agriculture water supply internalization. Water supply internalization is the process of measuring water security to estimate the degree of water supply sustainably by region inside. According to water users, Water supply internalization could be divided into Agriculture and urban water supply internalization. Agriculture and urban water supply internalization are calculated in this study. This study employed a spatial model to analyze agricultural water supply internalization and its influencing factors. The results showed that the agriculture development associated with agricultural population and crop typology impacts agricultural water supply internalization. Urban water supply internalization increases lead to an increase in agricultural water supply internalization. The agricultural population’s spatial agglomerations lead to increased agricultural water supply internalization. Agricultural population’s spatial agglomerations mean neighborhood city agriculture population share similar trend. Agricultural and urban water supply internalization have spatial autoconnection. The study area consisted of 30 cities in four provinces in North China: Beijing, Tianjin, Hebei, and Shandong.
