UK National Ecosystem Assessment 2011 The national level analysis of the natural environment in terms of the benefits that it provides people. Ecosystem – a dynamic complex of plant, animal and micro-organisms communities and their non-living environment interacting as a functional unit Ecosystem services – The benefits people obtain from ecosystems
The Natural Environment White Paper 2011 Evidence base – the UK National Ecosystem Assessment Joining up the Government’s environmental monitoring, to enhance understanding the of ecosystem services
National Planning Policy Framework 2012 The planning system should contribute to and enhance the natural and local environment by: recognising the wider benefits of ecosystem services;
8 UK NEA Conceptual Framework REPLACE *Note that the term good(s) includes all use and non-use, material and non-material benefits from ecosystems that have value for people.
Air, land, water, and all living organisms ECOSYSTEMS Places (e.g: Broad Habitats) where biological, chemical and physical interactions occur. In terrestrial habitats these include above and below ground processes ECOSYSTEM APPROACH “the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way” Convention on Biological Diversity Building on the Millenium Ecosystem Assessment ECOSYSTEM SERVICES The benefits people get from ecosystems Supporting services Necessary for the delivery of other ecosystem services Soil formation, Nutrient cycling, Water cycling, Primary production Provisioning services Crops, Livestock, Game, Fisheries, Water supply, Wild species diversity (genetic resources) Regulating services Climate regulation, Detoxification & Purification, Disease/pest control Pollination Cultural services Environmental settings (gardens, parks, landscapes) Wild species diversity
Environmental settings contribute to a series of cultural goods enhancing well being

30% of services are in decline or a degraded state Soil condition – fundamental to productivity and biodiversity – degraded Pollinators are declining Marine fish catches are low + ecological impact of fisheries Present challenges

But ecosystem services are consistently undervalued in economic analysis and decision making Therefore the UK NEA explored: How and why the economic value of ecosystem services should be incorporated into decision making Importance of considering both market and non- market goods, and at different spatial scales Responding to the challenges
Case study: rural land use in Wales Potential economic value of conversion from farming to multi-purpose woodland
Natural England Ecosystem Services Pilots Three pilot areas each run regionally with technical aspects being coordinated nationally
UK NEA Follow on phase The overall aim to further develop and communicate the evidence base of the UK NEA and make it relevant to decision and policy making at different spatial scales across the UK. Further development of the economic analysis of the UK NEA.
UK NEA Follow on phase Further exploration of cultural ecosystem services and cultural, shared and plural values for ecosystem services Analysis of future ecosystem changes, applying and developing the UK NEA scenarios The development and enhancement of tools and other supporting materials for use by a range of key user groups from the public, private and voluntary sectors
Publications SYNTHESIS TECHNICAL REPORT
Advocacy - Plausible Future Scenarios How might ecosystems and their services in the UK change in the future under plausible scenarios? Changes in land use and greenspace?
NEA Urban Greenspace amenity scenario analysis 3 categories city parks, the urban/rural fringe and informal greenspace. Meta analysis of existing studies to generate value function Analysis of UK urban centres – proximity to homes and percentage land cover Change in greenspace land cover from NEA scenarios Use value functions and summing process for valuations of greenspace under scenarios
Substantial change in values with different levels of ecosystem service provision Importance of including valuation of non-market goods in decision making Responding to the challenges
Changes in the past 60-years Gains in production have impacted on other ecosystems and ecosystem services: 90% decline in semi-natural grasslands (through conversion) Fertiliser run-off impacted aquatic systems Coniferous forest plantations at the expense of other habitats
Present challenges & future outlook UK is, and will likely remain an active trading nation – trading in products of ecosystem services 2008: imported 50m tonnes biomass Significant overseas ecological footprint Influenced by social, economic and ecological changes elsewhere
Governance of the UK NEA 27 member Expert Panel (natural and social scientists, economists) 2 Co-chairs of the Expert Panel: Bob Watson (Defra Chief Scientist) and Steve Albon (Macaulay Institute) 12 member Client Group (funders) 26 member User Group (agencies, NGOs, private sector, other government departments) The assessment team: with ~400 authors, led by a team of Coordinating Lead Authors (CLAs) A Secretariat based at UNEP-WCMC
A move towards a sustainable future will require: Changes to individual and societal behaviour Adopting an integrated approach to ecosystems management Appropriate mix of regulations, technology, financial investment and education (i.e. multiple responses) Range of actors and collaborations: government, private sector, voluntary organizations, civil society at large Addressing issues at a range of spatial and temporal scales Moving forward
UK NEA has identified that there are still knowledge gaps, uncertainty and controversy in our evidence However, has also demonstrated: Have sufficient understanding to start managing ecosystems more sustainably Social benefits of such management Moving forward
Mourato et al – New primary data Questionnaire survey on interactions between environmental settings and health. A geographically referenced quota survey of 1,851 respondents Statistically significant relations between health measures of physical functioning/emotional well being and the use of the environmental settings of domestic gardens and local green spaces. Respondents who at least once a month visit non-countryside green spaces, such as urban parks, report significantly better health on both measures compared to those who do not. As do respondents who at least once a week spend time in their garden NEA Valuing health goods linked to environmental settings
Mourato et al Scenario valuation with existing data A change in natural habitats that causes a 1 percentage point reduction in sedentary behaviour - total benefit of almost £2 billion (using WTP-based values), across the three physical conditions (CHD, colo-rectal cancer and stroke) and the mental health condition considered (stress and anxiety) Value of health goods linked to some environmental setting likely to be high NEA Valuing health goods linked to environmental settings
Key challenges arising from NEA and other analysis Causality between physical exercise and greenspace is likely to be bi-directional A recent large scale study of nearly 5,000 Dutch people by Maas et al. (2008) found that the amount of greenspace in people’s living environment has little influence on their level of physical activity. Uncertainty of benefits of outdoor exercise relative to indoor exercise (Thompson Coon et al. 2011) NEA Valuing health goods linked to environmental settings
Key challenges arising from NEA and other analysis “no conclusive evidence on the strength of the relationship between the amount of green space and the level of physical activity..not possible to accurately value, at the present time, the health benefits of created exercise due to additional green space provision” Mourato et al.2010 NEA Valuing health goods linked to environmental settings
