Mangrove ecosystems: changes in landscape spatial patterns due to human disturbances (urbanization).
Discussion Topic: Mangroves, a mandate for the health and vitality of an estimated 22 million hectares of subtropical and tropical coastline ecosystems are increasingly disappearing as a result of human actions and urbanization. Highly adapted to a variable environment, mangroves provide many ecological values, geological structure, and have sustained the livelihoods of indigenous coastal cultures. As resilient as mangrove ecosystems are, these vital forests are being quickly depleted due to human disturbances. Along with their disappearance go the economic resources they provide, the coastal stability they create, the homes for many interdependent organisms that they provide and the alteration of an ecosystem that is irreplaceable.
