  1. 1. Climate Change and Land Management – SEPA’s roleJanet Moxley (Senior Scientist – Climate Change) and Lorna Harris (Wetland Ecologist), SEPA
  2. 2. Content• Climate Change (Scotland) Act – what is required? SEPA’s role?• Analysis of existing monitoring data (TOC and DOC)• Link to land management pressures• Developing policy and guidance
  3. 3. Climate Change (Scotland) Act 2009• 80% reduction by 2050• Six greenhouse gases• Interim target 42% 2020• Duties on public bodies to contribute to the delivery of targets in exercising its powers (including decision making)• Adaptation programme• Land Use Strategy by 2011• Energy Efficiency Action Plan
  4. 4. Other Scottish Policies• Government’s Economic Strategy• Adaptation Framework• Renewables Action Plan 20% by 2020 • 50% (electricity) by 2020 and 31% by 2011 • 11% (heat) by 2020 • 10% transport
  5. 5. SEPA’s role in addressing Climate Change• Keep up to date with climate change science• Advise Scottish Government• Regulate major energy users and producers under PPC and EU Emissions Trading Scheme.• Monitor key environmental parameters• Advise business on energy and resource efficiency and waste minimisation.• Promote sustainable flood management practices and lead flood warning• Promote soil conservation• Work with SEARs partners to minimise emissions from agriculture and rural land use sectors
  6. 6. TOC in Rivers • 58 sites river have > 10 years data. (All in N) • 39 of these showed TOC concentration increases, the rest no trend. • Only decreases were the Carron (Falkirk) and Forth (Craigforth) (< 10 y data). • Increases mainly in east. • Mean increase 0.12 mg/l/y – increase of 0.25 mg/l over 20 years (doubling). • Concs +vely correlated with flow • “Spikier” results at 15 sites in NE
  7. 7. DOC in Lochs • Good network of sites, but generally < 6 years data. • Decreases in concentration at 45 sites, increases at 8 sites. • Unclear why lochs show different trend to rivers
  8. 8. Land Management and Carbon• Changes in land management and use suggested as causes of increased carbon loss from soils (TOC increase in rivers)• Soils in Scotland contain ~3000Mt C• Peatlands contain 53% of Scottish carbon store• Scottish peatlands may accumulate up to 0.4 Mt C per year – if in good condition...• Floods Act requires sustainable approach to flood management• Restoring peatlands can help to mitigate climate change by improving carbon storage
  9. 9. • Work with SEARs partners to minimise carbon loss from all organic soils/peatland usages • Agriculture • Hydro schemes • Wind farms• Wind Farms - Various problems arise when a wind farm is located on peat; • Changes to hydrology (drainage/flooding) • Run-off, silt control • Uncertain terrain – variable peat depth • Excavated peat – suitable use?
  10. 10. • SEPA is working with SEARs partners, the Scottish Renewables Forum, and the wind farm industry to find solutions to the various problems (including waste peat)• Ongoing projects; • ‘Good practice guidance for wind farm construction’ – workshop in May 09, draft documents produced • Series of meetings with SEARs partners and members of the wind farm industry to discuss problems and identify solutions
