Peri-urban areas are characterized by multifunctional land-use patterns forming a mosaic of built-up and agricultural areas. They are critical for providing food and other agricultural products, livelihood opportunities and multiple ecosystem services, which makes them transformative where urban and rural spaces blend. We analyzed land use changes in a peri-urban micro-watershed in Southern India by using Google Earth data to understand the micro-level spatio-temporal dynamics. This study aims at understanding the peri-urban agriculture and landscape changes as related to the change in use of wastewater and groundwater for irrigation. The temporal dynamics of peri-urban system including the changes in built-up, paragrass, paddy rice and vegetable cultivation, groundwater and wastewater irrigated areas in the watershed were evaluated. The detected changes indicate that, as a consequence of urban pressures, agricultural landscapes are being converted into built-up areas and, at the same time, former barren land is converted to agricultural plots. The mapped land use data are used in landscape change modelling for predicting the peri-urban agricultural dynamics and the driving factors in the watershed. Combined with the mapping and modelling approaches for land use change analysis, our results form the basis for integrated resources management in the wastewater influenced peri-urban systems.

城郊地区的特点是多功能土地利用格局，形成了建筑群和农业区的马赛克。它们对于提供粮食和其他农产品，生计机会和多种生态系统服务至关重要，这使它们在城乡空间融合的地方具有变革性。我们通过使用Google Earth数据分析了微观水平的时空动态，从而分析了印度南部郊区微流域的土地利用变化。这项研究的目的是了解与废水和地下水用于灌溉的变化有关的郊区农业和景观变化。评价了周边城市系统的时间动态，包括集水区，草丛，水稻和蔬菜种植，流域地下水和废水灌溉区的变化。所检测到的变化表明，由于城市压力，农业景观正在转变为建成区，同时，以前的贫瘠土地也转变为农业用地。映射的土地利用数据用于景观变化建模中，以预测郊区农业动态以及流域中的驱动因素。结合用于土地利用变化分析的映射和建模方法，我们的结果构成了在受污水影响的城市周边系统中进行综合资源管理的基础。映射的土地利用数据用于景观变化建模中，以预测郊区农业动态以及流域中的驱动因素。结合用于土地利用变化分析的映射和建模方法，我们的结果构成了在受污水影响的城市周边系统中进行综合资源管理的基础。映射的土地利用数据用于景观变化建模中，以预测郊区农业动态以及流域中的驱动因素。结合用于土地利用变化分析的映射和建模方法，我们的结果构成了在受污水影响的城市周边系统中进行综合资源管理的基础。
