Intensive inland aquaculture ponds, commonly found in the delta regions of various countries, have increasingly threatened nearby ecosystems over the past few decades. Although some progress has been made in implementing effluent treatment strategies to protect these biodiversity-rich areas, significant gaps still need to be in developing approaches suitable for needs of developing countries. Over the past thirty years, these inland aquaculture ponds have provided valuable hydrological, biogeochemical, and socioeconomic benefits to southern India. However, they also face serious challenges, such as poor planning during pond construction, intensification of farming practices, inadequate treatment and drainage systems, and a lack of social and political capacity to adopt modern technologies. This chapter examines the potential of geosynthetics in enhancing the sustainability of inland aquaculture ponds. It underscores the importance of coordinated efforts, from within-pond applications to regional strategies, to effectively utilize geosynthetics for creating barriers, protecting slopes, and improving drainage systems. The chapter also highlights the essential role of geosynthetics in fostering sustainable aquaculture practices and reducing the environmental impact of these ponds.
