Ecosystem Services and The Natural Capital Project
Emily McKenzie
2 April, InVEST Introductory Seminar, Bangkok
Republic of the Marshall Islands
Despite their importance, ecosystem services are often not considered in decisions.
This is because we lack practical, credible information about their value.
The Challenge
Outline
1. Ecosystem services– What is the concept?– How is it being applied?
2. Natural Capital Project– Strategy – Content and philosophy of our work
Ecosystem Services• Links nature & human welfare
• Integrate environmental values & trade-offs in decisions
• Nature supports us in countless ways: – stores carbon to slow climate change, – purifies and regulates water supplies, and – provides foods and medicines – provides opportunities for spiritual and cultural
experiences
The Basics
• Impact of nature on human well-being known since antiquity
• History of natural resource management for survival
History
Bust of Plato
• From 1960s on, “environmental services” coined, ecological economics developed
• First global studies and analyses
• First global assessment of ecosystem services• 2001-2005, 1360 scientists• Over the last 50 years, out of 24 services: – 15 have seriously declined – 4 have shown some improvement– 5 are generally stable but under
threat in some parts of the world
Millennium Ecosystem Assessment
ES = The benefits that people obtain from ecosystems
• Provisioning services - goods like food, water, timber, and fiber;
• Regulating services - stabilize climate, moderate risk of flooding and disease, protect water quality;
• Cultural services - recreational, aesthetic, educational, spiritual benefits; and
• Supporting services - underpin the others, e.g. photosynthesis, nutrient cycling, preservation of future options
Definition and Categorization
Natural Capital the goods and services from nature which are essential for human life
• Well-being - considering the impacts on people of having or losing these benefits

Why assess ecosystem services?
• Important for human wellbeing and prosperity
• More comprehensive accounting of impacts
• Engage a wider array of stakeholders
• Generate financing for conservation
• Innovative policy mechanisms
New tools to help• General assessments of ES– Reports– E.g. Millennium Ecosystem Assessment, TEEB
• Assessments of dependence and impact on ES– Work books – E.g. WRI’s Corporate Ecosystem Services Review, Impact
Assessment Review,
• Mapping of ES under alternative scenarios– Software tools– E.g. InVEST, ARIES
– Tools: Make it easy to quantify ecosystem services– Evidence: Test tools, improve decisions, share stories– Influence: Inspire policy change globally
Introducing the team
Terrestrial & freshwater science
Marine science
Standing on the shoulders of many…
…giants
Unlike the accounting tools we apply to measure the value of traditional economic goods and services… we have no ready set of existing accounting tools to measure the value of ecosystem services. Absent these, ecosystem services are invariably undervalued or not valued at all – by governments, businesses, and the public.
Who and what will catalyze the next giant step forward? Part of the answer lies with improving science.

Success = inform decisions– How would a proposed dam or logging project affect
ecosystem services and biodiversity?
– What would be the best marine spatial plan for balancing different stakeholders’ goals?
– How would upstream deforestation affect the quality & quantity of water downstream?
– Where might REDD and payments for watershed services projects be feasible?
ANSWERS:Accounting tools for quantifying ES
Filling the Gap
Policy decisions:Region/landscape scale
Short timelineForward looking, comparative
Assess tradeoffs
GLOBAL, SYNTHETIC60% of global ES in decline (MA, 2005)$33 Trillion/y (Costanza et al. 1997 Nature)
LOCAL, SPECIFIC
2 forest patches: $60K/yr (Ricketts, 2004. PNAS)
22 others (just for pollination!)

Support policy and practice globally
• Researchers– TEEB– Academic collaborators around the world
• Governments– GEOBON– IPBES
• Multilaterals and donors– World Bank & WAVES – UNEP, UNDP– Millennium Challenge Corporation
• Business– World Business Council for Sustainable Development– Business for Social Responsibility– Multilateral companies e.g. Dow, Coke
