Thondamanaru Lagoon , Thondamanaru Lagoon © Kumudini Ekaratne, IUCN, 2014
Development options for Thondaimanaru lagoon is developed and presented to the authorities .
The current situation of the Thondaimanaru lagoon is that there is no updated data on the fauna and flora of the Thondaimanaru lagoon (Northern Province or Sri Lanka).
But the overall picture of the ecosystem component and their interaction is needed as it is essential for the Conservation and Environmental education purpose. Here the environmental education purpose is very important because the school and University students of the particular region are not having good ecological field laboratory /destination. It needs not only enrich their knowledge but also contribute the Conservation strategic plan directly and indirectly.
The main causes for the problem were the 30 years lasting war, Due to the prevailed war there were high security tensions. The war has made two situations. One is security and due to that the field survey and field education was not feasible.
The groundwater in the Peninsula is already subjected to serious deterioration threats such as salinization and pollution due to anthropogenic activities.
As a part of the remedy of the above problem, a number of desalinization schemes have been implemented in the inland lagoons of the Jaffna Peninsula in the past to meet the fresh water needs of the Jaffna Peninsula. – Such as constructing barrages and bridges near the points where the sea water invades into the inland lagoons mainly at the Thondaimanaru lagoon region.
Second cause is the poverty and less livelihood opportunity due to the prevailed war situation, the internal displacement and land mines fear in the isolated area like lagoons. The sophisticated instruments such as binoculars’, field camera, mud sampler, environmental probes etc, were not allowed to use in the field during the war periods.
Now the 30 years lasting war is over the security risk also relaxed. The desalinization scheme within the Jaffna peninsula has been re-implemented and the barrages were reconstructed, under development schemes for the region. Now the Thondaimanaru barrage is functioning as expected.
Conversion of salt water lagoons into fresh water bodies may impose physical, chemical and biological changes in the surroundings of the inland lagoons, as well as in shallow groundwater environments and soils.
Therefore, it has to be monitored periodically to evaluate the environmental issues that may result in case of a successful outcome of desalinization of lagoons so it is an ideal time to start working. Numbers of families are being resettled close to the lagoon area and started their livelihood activities.
Also by doing this project it is able to contribute the livelihood as it is having funds for community livelihood activities. So through that the poverty issue can be addressed.
Academics, university students, school children, policy planners, general public (including the community surrounding the lagoon), nature tourists (mainly bird watchers) and tour guides
Data base on fauna and flora hydrological and socioeconomics
Management plan for the Thondaimanaru lagoon
five documentary films
Field guide titled Guide to the Thondaimanaru Lagoon
1. Data base on fauna, flora, hydrological and socioeconomic information of the Thondamanaru Lagoon.
2. A field guide to Thondamanaru Lagoon.
3. Documentary film on the Thondamanaru Lagoon.
4. 30 trained as Tour Guides.
The climate change is being addressed by measuring the lagoon water level and by observing the climate change indicator in the species. The Gender equity assured when conducting work shops and field works. Communication is achieved through production of booklets in all three languages and documentary films.
