Integrated analysis of land use and water quality: Economic, hydrological and policy analysis

Project Description:

Land use and changes in that use play a major role in determining the quality of rivers and lakes. Indeed the effectiveness of water quality management will always be compromised without a clear understanding of land use influences. However, land use is determined by a complex array of drivers including policy (e.g. CAP, WFD, etc.), market forces (e.g. changes in commodity prices, input costs, etc.), cross-sectional environmental variation (e.g. soil type, rainfall, etc.) and temporal environmental variation (e.g. the effects of climate change such as temperature variance, etc.). The applicants have extensive experience of modelling land use and their expertise has been recognised both through papers in the leading peer-review international journals (e.g. Fezzi and Bateman, 2011) and by their work forming the basis of the UK National Ecosystem Assessment (for which UEA lead the economic analysis; see UK-NEA, 2011) and in turn became the empirical underpinning of the UK Natural Environment White Paper 2011.

The workpackage will build upon and extend this prior work to link with the world-renown hydrology group (also at UEA) to generate integrated land-water models capable of predicting the impact of new scenarios defined by changes in the above drivers; e.g. policy change. The outputs of this analysis will be quantified assessment, for each scenario, of

     (i) land use (e.g. crop type, stocking species and intensity, etc.)
     (ii) food production and its value (e.g. £/ha)
     (iii) farm incomes (e.g. £ per farm household)
     (iv) water chemical quality (e.g. nutrient status, mg/litre)
     (v) water ecological status (e.g. WFD measures)
