Scottish Natural Heritage Dualchas Nàdair na h-Alba Scotland’s Natural Capital Asset Index Tuesday 3 May 2016
1.What is natural capital? 2.What is (the point of) the NCAI? 3.Can we improve the NCAI?
Natural capital Social & human capital Financial & manufactured capital What is natural capital?
Natural capital = “A configuration (over time and space) of natural resources and ecological processes, that contributes through its existence and/or in some combination, to human welfare.” Natural capital Habitats Individual assets Living (e.g. biological stocks, biodiversity) Non-living (e.g. natural cycles, mineral deposits) Productive Configuration Spatially Functionally Temporally Combination (with other capital) Underpinned by ecology and geology NATURAL CAPITAL
ECOSYSTEM SERVICE SUPPLY CONTRIBUTION TO HUMAN WELL- BEING Inputs from other capital ECOSYSTEM SERVICE DEMAND What is natural capital? Natural capital
What is (the point of) the NCAI? Provide a valid and transparent framework for monitoring change in Scotland’s natural capital The NCAI is included as an indicator in the National Performance Framework
Natural Capital Asset Index 1950 to Base year 2000 = 100 Year QUANTITY QUALITY
What is the NCAI?
Quantity Quality – Potential and Actual
Quantity Countryside Survey (Land cover) EUNIS Land Cover of Scotland
Quality - Potential
Quality - Actual 42 indicators of habitat quality used in the NCAI. For example: Site condition monitoring Bird surveys Butterfly surveys Agriculture statistics
Quality - Actual Indicator A Indicator B
Can we improve the NCAI? ecosystem functions ecosystem processes ecosystem service supply ecosystem service demand human wellbeing VALID AND TRANSPARENT MODEL? Natural assets
Criteria for quality indicators Data available for more than one year, ideally since 2000 Updated regularly Good coverage in Scotland Indicator of natural capital (rather than ecosystem service flows) No major confounding factors
Can we improve the NCAI? Multivariate analysis Normalisation Weighting Sensitivity analysis
Next update January 2017 – open data? Consistency after this?
Thank you
