A Global Meta-Analysis of the Value of Ecosystem Services Provided by Lakes

September 12, 2017 |

This paper was originally published in Ecological Economics.

Highlights:

We conduct the first meta-analysis on the value of ecosystem services provided by lakes.

We analyze results of 133 studies, offering a total of 699 values.

We show that antagonisms and synergies across ecosystem services are perceived and valued by people.

“This study presents the first meta-analysis on the economic value of ecosystem services delivered by lakes. A worldwide data set of 699 observations drawn from 133 studies combines information reported in primary studies with geospatial data. The meta-analysis explores antagonisms and synergies between ecosystem services. This is the first meta-analysis to incorporate simultaneously external geospatial data and ecosystem service interactions.

We first show that it is possible to reliably predict the value of ecosystem services provided by lakes based on their physical and geographic characteristics. Second, we demonstrate that interactions between ecosystem services appear to be significant for explaining lake ecosystem service values. Third, we provide an estimation of the average value of ecosystem services provided by lakes: between 106 and 140 USD$2010 per respondent per year for non-hedonic price studies and between 169 and 403 USD$2010 per property per year for hedonic price studies…”

Introduction from Carl Obst (2017)

Victor Hugo once wrote that “Nothing is so powerful as an idea whose time has come”. Recognising the true value of natural capital, is one such idea. Across private and public sectors, across disciplines, and around the world, initiatives to advance and develop natural capital thinking have emerged rapidly over the past 10 years.

In a blizzard of acronyms, we have the NCC, SEEA, WAVES, IIRC, KIP-INCA, A4S, GRI, EO4EA – among many others. Are they the same, are they competing, are they useful? To both insiders and outsiders this range of initiatives is confusing at best. At worst, it leads to a lack of engagement, avoidance and misunderstanding.

The reality is that, while differences among these various initiatives do exist, they have all been motivated by a common understanding of the reality that we are losing our stocks of natural capital – and that this matters.

While each initiative may have different origins, some differing objectives, and may reflect variations in technique and method, there is much common ground. Indeed, to engage the broader community in tackling the natural capital challenges we collectively face, we cannot afford to focus on distinctions. Instead, we must look to build on the overlaps and seek to build a common language that will enable the exchange of ideas and ongoing innovation.

It is in this spirit of collaboration that the Natural Capital Coalition, together with the IDEEA Group and supported by over 20 organisations, launches this statement on Combining Forces on Natural Capital.

It is especially relevant that this statement of collaboration is launched at the World Forum on Natural Capital, where leading voices in the movement gather every two years, to share best practice, enduring challenges and build further collaborations.

While progress to date has largely taken place in small pockets, in order to move forward we need to ramp up our efforts and move beyond talking with supporters and “the converted”.

For this, we need leaders who can establish spaces for dialogue and development, and who can ensure that technical debates do not form a barrier to progress, that we take full advantage of the diversity of skills and experience already engaged, and that the big picture is always kept in mind.

I encourage you to take the opportunity to read the statement, to share it within your organisations, to sign on, and to join us as we move towards a better understanding and appreciation of the complex and beautiful world in which we live.
