How is the biodiversity within an ecosystem related to the ecosystem's function? Quantifying and understanding this relationship—the biodiversity-ecosystem function (BEF) —is important because socio-economic development is almost always accompanied by the loss of natural habitat and species. Short-term economic gains may thus trump longer-term benefits for human society, creating vulnerabilities that could be avoided or corrected with enough knowledge about the role of biodiversity.

Experiments suggest that biodiversity enhances the ability of ecosystems to maintain multiple functions, such as carbon storage, productivity, and the buildup of nutrient pools (multifunctionality). However, the relationship between biodiversity and multifunctionality has never been assessed globally in natural ecosystems. We report here on a global empirical study relating plant species richness and abiotic factors to multifunctionality in drylands, which collectively cover 41% of Earth’s land surface and support over 38% of the human population.

The mainstream paradigm of understanding grass-root environmentalism in India as “environmentalism of the poor” might be challenged by an alternative prototype forest movement in the Bengal Dooars prior to the Chipko movement. It was fought against the exploitative design of ecosystem governance under the taungya method of artificial regeneration as invented by colonial foresters during the British rule.

Environment Matters interviews Glenn-Marie Lange, program leader, WAVES, and team leader, Policy and Economics, at the World Bank’s Environment Department, on the progress made in establishing global accounting systems that incorporate natural capital.

Marianne Fay, chief economist for the World Bank Sustainable Development Network, led a study on green growth, defined as growth that is effi’cient, clean, and resilient: e’cient in its use of natural resources, clean in minimizing pollution and environmental impacts, and resilient in fully accounting for natural hazards. Here, Environment Matters interviews Fay on what the study means.

This paper focuses on the causes of ecosystem degradation. Historically, poor communities have been identified as among the key degrading agents. The thesis of this paper is that such communities do not voluntarily destroy the resource base which is the source of their livelihoods and provides them sustenance. Therefore, the damage that they visibly cause is induced by institutional failure.

Juha Siikamaki estimates the recreational value of America's financially strained state parks.

Programmes to address global warming and promote green development, such as Payments for Ecosystem Services and Reduced Emissions from Deforestation and [forest] Degradation financed by carbon-offset trading, are framed by a world-as-market paradigm that subsumes social goals within a project of globalized eco-economic management. Because market-based strategies reinforce existing property claims and power relations, Kathleen McAfee argues that they are likely to worsen inequality without yielding net, global environmental benefits.
