Ecosystem services, the benefits humans derive from nature, represents a radical departure in our perception of linked environmental and social problems and the actions we need to undertake to address those urgent challenges. Due to its increasingly widespread policy prominence, understanding and appraising its conceptual and practical benefits whilst at the same time acknowledging its potential pitfalls represents an important endeavour. Comprising seven parts and sixteen chapters, the first five parts of the thesis outline the main environmental and social challenges we face, presenting the core foundations, contemporary debates and developments in ecosystem services scholarship, whilst also underlining its increasing coalescence with sustainability discourse. In Part 6 we focus on a key application of ecosystem services with respect to its translation into incentive-based environmental management schemes, namely: payment for ecosystem service programmes and agri-environment schemes. We present a systematic global analysis of payment for ecosystem services programmes, highlighting the successes and challenges they face, whilst also providing an approach to improve their design and evaluation as a route to maximise their effectiveness. Turning our attention to a globally significant ecosystem, the thesis assesses the prospects for jointly developing seagrass Blue Carbon initiatives and payment for ecosystem service schemes, arguing that complementing these activities would produce significant climate, conservation and livelihood benefits. Switching contexts, from focusing on incentive schemes primarily in operation in developing countries to those designed to balance productivity and conservation matters in the agricultural sector of developed countries – the thesis explores the stakeholder and institutional factors affecting agri-environment scheme operation and implementation through the eyes of key operatives. Finally, in Part 7, I argue that a landscape framing and approach to ecosystem services provides an effective route to improve environmental management decision-making and policy as well as comprehensively addressing the linkages between ecosystem services and human-wellbeing
