Final Report Ecological Profile for Coastal Talukas of Gulf of Kachchh OVERVIEW Sponsored by Gandhinagar by Gujarat Ecology Society in association with Foundation for Ecological Security MIR Projects and Consultants September 2014 GES FES MIR _________________________________________________________________________________ A DYNAMIC ECOSYSTEM It is a matter of concern and, at the same time challenge, to deal with increasing pressures on a varied and fragile ecosystem spanning almost one- third of Gujarat’s coastline. The Gulf of Kachchh has been attracting navigators over the centuries. However, the decisive economic push that Gujarat is witnessing since its formation and more so, during the last one and a half decades, has been bringing great pressure on natural resources on all sides of the Gulf. Gujarat has shown foresight in understanding the pressures on land, flora and fauna, water and other resources to reduce the adverse impact of economic development on ecology. This extensive study of the talukas around the Gulf rim and beyond is a case in point. The detailed taluka-wise study of ecology of a 550 km coastline and its hinterland planned by Gujarat Ecology Commission will make enormous data available to planners to achieve the twin objectives of economic development and conservation of natural resources to a large extent. In this process we at Gujarat Ecology Society (GES) feel privileged to present this comprehensive document covering a whole range of data that goes beyond simple profiling. An effort has been made to indicate a management plan for each of the threatened segments of ecology. Over a period of nearly two decades GES has acquired capability to undertake such a task. Much earlier GES undertook a survey of entire Gujarat coast –covering 10 kms onshore and 10kms offshore – bringing it out in four volumes. The study being presented here is more detailed in its scope and content and has authenticity of a higher degree having been reviewed and vetted by experts. We express our appreciation of GEC’s foresight and our thanks for giving us an opportunity to be a part of their on- going enlightened approach.
