Abstract:
The national development demands and local resource losses in village
tank cascade systems in the Greater Hambanthota Project (GHP) area were investi-
gated. The aim of the study was to identify mega-development projects and their im-
pact on the natural environment and resources of tank cascade system. The study
utilized qualitative methodology, involving 27 interviews with local farmers, govern-
ment officers, NGOs, and government representatives and direct observations. The
study revealed that the rapid development in Hambanthota city has severely impacted
the upper part of the cascade and leading to eroded embankments, sedimentation, and
reduced natural water flows. Despite the region’s infrastructure development, the at-
tention, management and development of tanks and irrigation systems has installed,
new proposals have not implemented. It caused to damage to the embankments, re-
duced their drainage capacity and created challenges for their sustainable, widespread
utility. New development interventions in Hambanthota City and Mirijjawila areas
have led to increased deforestation, fragmentation of wildlife habitats, and increased
the arrival of elephants in villages. Therefore, the human-elephant conflict have been
a modern socio economic and environmental issue in the area, during the last few
years. As a conclusion, mega development projects, have neglected local capacities,
resources, and development requirements of the area and causing harm to locals and
wildlife with diminishing their resource-base. Researchers suggest mega-develop-
ment projects should consider local resources and community engagement while in-
troducing national policies and existing policy integration to sustainably address con-
flicting demands
