-PART 1: How marine protected areas adapt and mitigate to climate change PART 2: Marine protected areas in Morocco - the impact of climate change on MPAs In view of the deteriorating state of marine ecosystem and biological resources, the marine protected area (MPA) is proposed as one of several instruments to maintain an effective conservation policy. This instrument has two main objectives: the first is to protect the resources, and the second is to enhance the human activities that exploit these resources. In order to achieve these objectives, several difficulties have been mentioned such as the determination of the location of the MPA, its size, and the degree of protection. Ecological economics with the introduction of bio-economic models has combined biological and economic aspects to determine the impacts of the MPA.
