  1. Estates in TransitionClimate Change, Adaptation and MitigationDartington Hall Estate, Totnes11th June 2007 David Fursdon CLA President

  2. Challenge of Climate Change for land management in the SW • Impacts • Adaptation • Mitigation • First step – measurement • CALM – Climate Aware Land Management

  3. The climate for farming • Economic climate • Political climate • The climate climate!

  4. Twin challenges for the 21st Century: food and environment • More food • Higher standards of environmental protection • Renewable energy • Climate change increases these challenges

  5. The central importance of carbon • Mankind has to wean itself off fossil fuels • From hydrocarbons . . . to what? • Nuclear energy • Hydrogen • More carbohydrates • What produces these? • Photosynthesis • In the temperate zone or the tropics?

  6. Accounts are vital • Financial and management accounting • Nutrient accounts • Water accounts • Carbon accounts

  7. CALM – Climate Accounts for Land Managers • Work in progress by the CLA, Savills • sponsored by EEDA1 • Applies IPCC2 methodology to farming activities • Measures on-farm Green House Gas (GHG) emissions CO2, N2O, CH4 from • Energy use, Fertilisers, Cultivations & Livestock • Sets against this the carbon storage in • Soils, via land use change • Trees • East of England Development Authority • International Panel on Climate Change

  8. An example, Wiltshire Estate • Land Use 2778 ha • Arable 1374 ha • Grass 620 ha • Woods 777 ha • Other 7 ha • Livestock • 2100 sheep, 160 fallow deer, 70 roe deer • Other data • Energy use – all forms • Inorganic fertilisers used • Animal manure • Crop wastes • Woodland type, age and management

  9. Carbon account for a Wiltshire Estate – summary • Emissions t Carbon% • Energy use 83 14 • Nitrous oxide , ferts & livestock 476 77 • Methane from sheep 57 9 • Total 616 100 • Carbon storage from forest growth 638 • Net carbon storage 23 • We are repeating this analysis on a wide range of other farms and estates. • We explore the difference we can make by switching to renewable energy, and changing land use.

  10. Mitigation options • All industries must improve energy efficiency • Agriculture’s particular tasks • Fertiliser efficiency • Manure management • Anaerobic digestion • Soil andpeat management • R&D is essential

  11. Unique contribution of land managers • Land management is the only sector able to make a positive contribution. • The three main routes are: • Energy substitution • Material substitution • Carbon sequestration

  12. Can these be earners?

  13. Collective actions to launch these developments • Government has to decide who is paying to internalise the climate impacts • Taxpayer • Consumer • Can land management join carbon trading?

  14. Concluding remarks • Excitement at opportunities • Concerns at implications • Long term nature of land ownership • Need for practical accounting • Steep learning curve ahead
