The Climate, Land-use, Energy and Water Systems (CLEWS) models are focused on assessing interlinkages between resource systems in order to understand how production and use of food, energy and wate
r security resources may contribute to climate change, and how climate change may affect resource systems. The models also assess where pressure points exist and how to minimise trade-offs. This type of framework for integrated resource assessments involves a strong quantification process which requires the development of sectoral models (for water, energy and land use), taking in consideration different climate futures. The framework is applicable to different geographical scales, from global, to regional, national and urban levels.
