The enrichment of brackish and coastal waters provided by the mangrove vegetation may be substantial and should not be overlooked. As mangroves become smaller and more fragmented, important ecosystem goods and services will be diminished or lost. Our results show that by constraining the admissible patterns of connection, and using an adaptive law based on the difference between the nodes, we can guarantee the stability of the synchronized solution of the network despite structural changes. Ministry of Livestock and Fisheries Yangon, Myanmar. Mangroves are being destroyed at rates 3-5 times greater than average rates of forest loss and over a quarter of the original mangrove cover has already disappeared; driven by land conversion for aquaculture and agriculture, coastal development, pollution and overexploitation of mangrove resources.
