Scenarios for Ecosystem Services: An Overview
نویسندگان
چکیده
The Millennium Ecosystem Assessment (MA) scenarios address changes in ecosystem services and their implications for human well-being. Ecological changes pose special challenges for longterm thinking, because of the possibility of regime shifts that occur rapidly yet alter the availability of ecosystem services for generations. Moreover, ecological feedbacks can intensify human modification of ecosystems, creating a spiral of poverty and ecosystem degradation. Such complex dynamics were evaluated by a mixture of qualitative and quantitative analyses in the MA scenarios. Collectively, the scenarios explore problems such as the connections of poverty reduction and ecosystem services, and trade-offs among ecosystem services. Several promising approaches are considered by the scenarios, including uses of biodiversity to build resilience of ecosystem services, actively adaptive management, and green technology. Although the scenarios do not prescribe an optimal path, they illuminate the consequences of different policies toward ecosystem services.

Using Participatory Scenario Planning to Identify Ecosystem Services in Changing Landscapes
There is a growing interest in assessing ecosystem services to improve ecosystem management in landscapes containing a mix of different ecosystems. While methodologies for assessing ecosystem services are constantly improving, only little attention has been given to the identification of which ecosystem services to assess. Service selection is mostly based on current state of the landscape alth...

متن کاملRole of rainwater harvesting for improving the human well-being and ecosystem services
Ecosystem services are fundamental for human well-being and are the basis of rural livelihoods, particularly for poor people. Rainwater harvesting can serve as an opportunity to enhance ecosystem productivity, thereby improving livelihoods, human well-being, and economies. Rainwater harvesting has been shown to create synergies between landscape management and human well-being. These synergi...
