Alternatives to Comprehensive Ecosystem Services (ES) Markets: The Contribution of Forest-related Programs in New Zealand Arun P. Bhatta, Hugh Bigsby and Ross Cullen Faculty of Commerce, Lincoln University Research Outline: • Introduction • Literature Review • Research Questions • Methodology • Significance of the Research 1. Introduction: Ecosystems through natural processes and components provide various goods and services which we refer to as ecosystem services (ES) Table 1: The condition of ES Ecosystem services Degraded Mixed Enhanced Provisioning Capture fisheries Wild foods Wood fuels Genetic resources Biochemicals Fresh water Timber Fibre Crops Livestocks Aquaculture Regulating Air quality regulation Regional & local climate regulation Erosion regulation Water purification Pest regulation Natural hazard regulation Cultural Spiritual & religious values Aesthetic values Source: (WRI, 2007) Recreation & ecotourism The condition of ES in New Zealand • Current land use practices have severely degraded ES such as air, water, biodiversity, and soils (Baskaran et al., 2009; Clark et al., 2007; Cook, 2008; Hughey et al., 2008; MfE, 2009; Moller et al., 2008) • Impact on economy Primary production exports - $25.9 billion in 2009 Tourism - $21 billion in 2009 2. Literature Review 2.1 Why ES are degraded? • Public/quasi-public goods and market failure • Market systems and perverse subsidies • Lack of incorporation of ES values into resource allocation decisions 2.2 Approaches to ES provision • CAC (product, input or technology standards) • Economic (dis) incentives (subsidies and tax reductions or levying taxes and fees) • Legal and ethical tools – liability laws, moral suasion MBIs to create economic incentives Table 1: Market mechanisms for ES Mechanism Commodified ecosystem service Sites of application Markets for • Emission trading of greenhouse gases ES (atmospheric sink functions of CO2) • Sulphur dioxide emission trading (atmospheric sink functions of SO2) • Wetland mitigation banking • Nutrient trading around Lake Taupo Payments • Watershed protection for Ecosystem • Carbon sequestration Services • Habitat conservation / wildlife services (PES) • Bio prospecting • Agro environmental measures • Soil conservation • EU, United Kingdom, Chicago, New Zealand • USA through the US Clean Air Act of 1990 • USA • New Zealand Central America, Ecuador, Bolivia Costa Rica, Ecuador Bolivia, Zimbawe Costa Rica European Union, US New Zealand Source: Gómez-Baggethun et al., 2010 • Creation of ES market requires: Measuring flows of ES and valuing them, enforceable liability rules and property rights, and lower transaction costs • Other approaches to provision of ES (PES) focus on single services • However, in the provision of a particular ES, there are spin-off effects Hence, studying those spin-off effects may provide a simple and cost effective way of ensuring wide range of ES 3. Research questions Main aim is to study the effectiveness of alternatives to broad ecosystem services markets in providing multiple ES • Do limited focus programmes provide broad ecosystem service outcomes? • Are there differences in ecosystem service outcomes between various policy approaches? • Which approach is most cost effective in the provision of ES? 4.

Significance of the research • Wider in scope – approach and method • Findings will help in future ES restoration efforts Comments/ Suggestions
