Environmental markets' news & resources: species, wetlands, habitat and biodiversity.
From May 2013, Madsen Environmental has handed over these reins. I'll continue the focus and trends of Nature+Economics here, and post on similar themes. Follow, suggest a Scoop, and offer advice and feedback as I curate
Our results from a meta-analysis of 621 wetland sites from throughout the world show that even a century after restoration efforts, biological structure (driven mostly by plant assemblages), and biogeochemical functioning (driven primarily by the storage of carbon in wetland soils), remained on average 26% and 23% lower, respectively, than in reference sites. Either recovery has been very slow, or postdisturbance systems have moved towards alternative states that differ from reference conditions. We also found significant effects of environmental settings on the rate and degree of recovery. Large wetland areas (>100 ha) and wetlands restored in warm (temperate and tropical) climates recovered more rapidly than smaller wetlands and wetlands restored in cold climates. Also, wetlands experiencing more (riverine and tidal) hydrologic exchange recovered more rapidly than depressional wetlands. Restoration performance is limited: current restoration practice fails to recover original levels of wetland ecosystem functions, even after many decades. If restoration as currently practiced is used to justify further degradation, global loss of wetland ecosystem function and structure will spread.
Report from the Workshop on Indicators of Final Ecosystem Goods and Services for Wetlands and Estuaries. " In this report we attempt to give practical meaning to the final ecosystem services concept. This takes the form of a working hypothesis on the units that need to be measured or estimated. We have made significant progress; we expect refinements with future research. "
It's not just about being a do-gooder. Cary Krosinsky reports that companies--and the investors who follow them--make out like bandits when they're environmentally responsible.
"Take NEWSWEEK’s Green Rankings, for example: companies that ranked in the top 100 of the 2009 ranking, weighted equally, outperformed the S&P 500 by 4.8 percent over the last two years. These companies are collectively up 15.2 percent, compared to 10.4 percent for the S&P 500."
The research aims to provide a ranking of corporate impacts on the natural environment and by highlighting the scale of the financial risk, provoke debate about what this means for long-term business and shareholder value.
The biodiversity check... will provide arguments for decision making regarding the company’s strategy on biodiversity. It assesses, according to the procedure of environmental management systems EMAS III and ISO 14001, potential negative impacts on biodiversity of individual business units, manufacturing facilities, products or processes, and identifies potential risks and opportunities.
Method: "In an extraordinary feat of data collection spanning years, the researchers from the University’s Integrated Sustainability Analysis group in its School of Physics gathered data on five billion supply chains, and 15,000 commodities in 187 countries, and compared all this to a register of 25,000 endangered species."
Conclusion: "It’s across the board, the researchers say: developed countries’ demand for sugar, coffee, tea, timber, textiles, and raw materials for manufactured goods (read: blood minerals for electronics) all export environmental destruction to the supplier and cause “a biodiversity footprint that is larger than at home”
