The purpose of Winter School – 2017 (November 27th – December,4th 2017) was to conduct a field based study to understand the water and sanitation problems, especially the pollution in Alappuzha canals to devise a mitigation plan. It also provided a platform to students to interact with and learn from experts, practitioners and local people and goes beyond classroom learning to understand the complexities of waste water and sanitation issues. The exercises like WS-2017 can facilitate the process of bridging the knowledge – technology – decision making/ implementation gap. It will also contribute to a new pedagogy of field based learning to engineering/ science/ social science students.
