Spatial planning for adapting to climate change

Area of Science:

• Environmental science
• Hydrology
• Ecological modeling

Background:

• Regional hydrologic systems integrate climate, human activities, and ecological processes via water interactions.
• Intensified human interference in these systems necessitates integrated modeling approaches.

Purpose of the Study:

• To simulate the ecological effects of climate change on riverine grasslands.
• To model the long-term development of land use and water management under climate change.
• To assess the impact of agricultural development on ecological benefits and peak discharges.

Main Methods:

• Coupling an integrated regional hydrologic model with an ecologic evaluation model.
• Developing an integrated 'bio-economic' model including agricultural development.
• Simulating autonomous development scenarios in response to climate change.

Main Results:

• Simulated ecologic effects of climate change on mesotrophic riverine grasslands are positive.
• Peak discharges exhibit high sensitivity to precipitation.
• Autonomous agricultural development leads to increased field drainage, potentially reducing positive climate change effects on grasslands.

Conclusions:

• Climate change offers ecological benefits to riverine grasslands, but agricultural practices like increased drainage can counteract these.
• Managing regional development is crucial to harness ecological opportunities while controlling peak discharges.
• Flow retardation in upstream areas is a viable strategy for managing peak discharges.
• Bio-economic modeling aids in anticipating climate change impacts through spatial planning.
