Ecosystem Services Meets Systematic Conservation Planning

by Liz Law

This week saw the inaugural joint meeting of the Ecosystem Services Discussion Group and the Marxan Party to discuss software and tools for planning and prioritization of Ecosystem Services.

The Ecosystem Services framework has developed in recent years, encapsulating land stewardship to foster the many benefits that we derive from our ecosystems. These benefits are many and multifaceted, ranging from agricultural production and climate change mitigation, to regulating watersheds, and stimulating inspiration in diverse cultural settings. However, like biodiversity, planning for ecosystem services requires balancing the management requirements of a diverse range of sometimes opposing land uses, resulting in potentially complex, multi-criteria problems.

Ecosystem services, meet Systematic Conservation Planning.

Systematic Conservation Planning has grown from the need to solve multi-objective allocation problems in a repeatable, transparent way. Typically focused on multiple species or ecosystems, Systematic Conservation Planning has increasingly accounted for real world complexities such as direct and opportunity costs, equity of impact, physical and thematic connectivity between planning units, and contribution of multiple land use types.

Resolving the ‘Environmentalist’s Paradox’, and the role of ecologists in advancing economic thinking

Ecologists do have a tendency for making dire warnings for the future, but for anyone concerned about the myriad of problems currently facing the Earth — climate change, an ongoing wave of species extinctions and impending peak oil, phosphate, water , (everything?) crises – the continued ignorance or ridicule of such warnings can be a frustrating experience. Environmental degradation and ecological overshoot isn’t just about losing cute plants and animals, given the widespread acceptance that long term human wellbeing ultimately rests on the ability for the Earth to supply us with ecosystem services.

In light of this doom and gloom, things were shaken up a bit late last year when an article1 published in Bioscience pointed out that in spite of declines in the majority of ecosystem services considered essential to human wellbeing by The Millenium Ecosystem Assessment (MA), aggregate human wellbeing (as measured by the Human Development Index) has risen continuously over the last 50 years. Ciara Raudsepp-Hearne and the co-authors of the study suggested that these conflicting trends presented an ‘environmentalist’s paradox’ of sorts – do we really depend on nature to the extent that ecologists have led everyone to believe?
