Abstract

Surface water management at agricultural catchment level is one of the challenging and most difficult tasks due to the multidimensional and non-point contamination sources. Contamination of surface water by various emerging pollutants released from agricultural has drastically increased due to difficulties in identification of contamination type and sources. The study reveals the sustainable technological and participatory strategic modelling frameworks for surface water management at agriculture catchment level. The study explains the demonstration of pollution remediation techniques, which are self-sustaining, and solar-energy utilization. In
addition, conceptual modelling frameworks with integration of participatory and monitoring (GIS-RS) approaches were developed by considering socio-economic and climate change trends in the region. Self-sustaining remediation techniques such as bio-fencing & low-cost (indigenous) adsorbents at agricultural catchments were designed for sustainable pollution management and water conservation.

Methodology:
The methodology mainly includes demonstration of self-sustaining pollution remediation techniques using low-cost and indigenously based adsorbents. Utilization of solar-energy as an alternative driving energy and conceptual models with integration of participatory and monitoring (GIS-RS) approaches. The methodology includes field observation, survey and public participatory, conceptual modelling and field test.

Benefits:
The major benefits of the study are identification and mitigation of unidentified sources that helps sustainable management of surface water at catchment level.

Analysis and results:
The sustainable & technological approaches can be implemented for the catchment level as well as rurban level for the potential management and mitigation of water contamination by undefined sources.

Conclusion:
Self-sustaining remediation techniques such as bio-fencing & low-cost (indigenous) adsorbents in bunding at agricultural catchments have addressed for sustainable catchment management and surface water  conservation. The role of citizen science and individual attitude change towards water conservation is crucial and important to avoid non-point pollution sources at agricultural catchment.
