However, it is also a fragile ecosystem which is exposed to environmental degradation due to oil exploration activities. Concern for mangrove environment demands that mapping of the mangrove environment should be carried out so as to know its current status. Conventional method is inadequate to achieve this due to the difficult terrain of the region. This research aims at detecting and mapping the presence of oil spill on water and land in the mangroves using microwave and optical remote sensing. The result proves that optical remote sensing has the potentials for detecting oil spill on the waterway. It also has the capability to detect oil spill on ground using the effects of oil on vegetation as proxy. The study is concluded by recommending further research work on radar as it could not discriminate between the backscatter of oil on land and that of soil with high water content.展开更多

Despite the technologically advanced equipment employed by ExxonMobil Guyana and affiliates, an oil spill could occur due to accidents, equipment failures, or sabotages. The selected coastal communities as the study areas in Region 1 and Region 2 could be adversely affected, particularly the mangrove ecosystems. Potential oil spill pollution will adversely impact mangrove ecosystems in Region 1 and Region 2. Mangroves offer significant benefits to coastal communities, such as coastal defence and carbon sequestration, which puts Guyana on the world map. The research aimed to investigate the mitigation strategies to manage the potential environmental risks on mangrove ecosystems in the coastal communities of Region 1 and Region 2. It followed a qualitative approach and conducted semi-structured interviews with the Toshaos of the selected coastal communities. The data analysis strategy was thematic analysis using the Nvivo software. The major themes included legal and policy frameworks, oil spill response strategies, community-based involvement, and monitoring and enforcement of regulations. The significant results included reviewing and updating the regulatory framework for mangrove management and conservation;oil spills mitigation measures such as containment and shoreline protection and cleanup, cost recovery and compensation, and limited monitoring and law enforcement of mangrove management and conservation regulations by inter-agencies. The regulatory and institutional framework is outdated and needs to be amended. The agencies overseeing mangrove management and conservation have overlapping responsibilities and require more coordination. There should be greater collaboration among agencies for mangrove management and conservation and improved monitoring and enforcement programmes through institutional support.展开更多
