Agroforestry & Sustainable Agriculture: Vast Potential to Lower Emissions, Store Carbon
6 Aug, 2009 05:34 pm
Researchers working on a joint World Agroforestry Centre-United Nations Environment Programme project suggest that integrating agroforestry in farming systems on a massive scale would create a vital reservoir for carbon storage. No less than a billion hectares of developing country farmland is suitable for conversion to carbon agroforestry projects, according to Intergovernmental Panel on Climate Change (IPCC) estimates.
Working to realize this goal is even more promising and feasible given that many of these "green" agricultural practices can be implemented at little or no cost. Moreover, the majority of this potential - 70 per cent - can be realized in developing countries, UNEP points out.
Fertilizer Trees & the Carbon Benefits Project
"If implemented over the next fifty years, agroforestry could result in 50 billion tons of carbon dioxide being removed from the atmosphere, about a third of the world's total carbon reduction challenge," Dennis Garrity, director general of the World Agroforestry Centre and co-chair of the Congress Global Organizing Committee, stated in a UNEP news release.
A study completed by World Agroforestry Centre scientists on fertilizer trees that capture nitrogen from the air and transfer it to the soil indicates that their use can reduce the need for commercial nitrogen fertilizers by up to 75 per cent while doubling or tripling crop yields. "These results should make agroforestry appealing to farmers," Garrity noted.
An inability to reliably measure, monitor, forecast and verify how much carbon farmers are capturing and storing is a major hurdle to realizing this goal.
In May, UNEP, the World Agroforestry Centre and the UN General Environment Facility being managed by the World Bank launched the Carbon Benefits Project, a partnership with an initial $9.16 million worth of funding that aims to bring together the latest remote sensing technology and analysis, soil carbon modeling, ground-based measurements and statistical analysis to fill this void.
The University of East Anglia's Overseas Development Group, Colorado State University, the World Wildlife Foundation (WWF) and Michigan State University are partnering with national organizations in a number of countries to see the project through to fruition.
Sealing the Deal in Copenhagen
UN Under-Secretary General and UNEP executive director Achim Steiner has been emphasizing the need to take a natural and man-made systems-wide approach as he has been promoting the widespread development, promotion and adoption of sustainable agricultural practices that can address food, energy and job security, as well as poverty and the preservation of biodiversity.
Steiner has also been urging government leaders and representatives to incorporate policies and measures that do so into any global climate change agreement that succeeds the Kyoto Protocol. Doing so is critical, particularly given the urgency of reaching a global climate accord in Copenhagen this December, a development that proponents have been working hard to bring about.
"Addressing the range of current and future challenges - from the food, fuel and economic crises to the climate change and natural resource scarcity ones - requires an accelerated transition to a low carbon, resource efficient Green Economy for the 21st century," Steiner stated.
Nations must seal the deal on a comprehensive and scientifically-credible new climate agreement in Copenhagen - there is a lot at stake, not least the future of agriculture and farmers' livelihoods. One key step will be for nations to agree to a scheme for Reduced Emissions from Deforestation and forest Degradation (REDD) which will pave the way for preserving forests and other key ecosystems, as well as closing the gap in global demand for sustainable timber by shifting production from forest to farm.
"Farming will be either part of the problem or a big part of the solution. The choice is straight forward: continuing to mine and degrade productive land and the planet's multi-trillion dollar ecosystems or widely adopting creative and climate-friendly management systems of which agroforestry is fast emerging as a key shining example."

Cash Is King, Even at Copenhagen
Although apparently brief, the suspension of the Copenhagen climate conference after a walkout by the Group of 77 developing countries confirms that the talks are as much about money as about healing the world's climate. It's not just that the G77 wants the Kyoto limits on the emissions of developed countries enforced, while leaving their own emissions uncapped; it also wants the developed world to kick in sizable sums--much bigger than the 2.4 billion Euros per year offered by the EU--to cover the improvements in energy efficiency and renewable energy that would enable them to tackle the growth of their own emissions. There's a solid argument there, though it is not the guilt-based logic of "carbon debt" that I explored a few weeks ago.

COP15: The Time is Now
In spite of the recent weeks of roller coaster-like expectations for a positive outcome from the COP15 climate conference that got underway Monday, the sense of urgency is keenly felt here at the Bella Center, home of the climate negotiations and exhibitions for dozens of NGO's and observer organizations.

$10.5 Trillion by 2030: the Number that Should be at the Heart of Copenhagen Climate Talks
Forget 80% by 2050 and 17% by 2020. Time to stop fixating on 450 ppm vs 350 ppm. As UN climate talks kick off today in Copenhagen, Denmark, there's only one number really worth the world's attention: $10.5 trillion. That's the additional investment required between now and 2030 to put the world's energy system on a lower-carbon path, according to the world energy watchdog, the International Energy Agency.

COP15 Primer : Developing Action to Reduce Global Warming Pollution
I'll discuss the willingness of developing countries to undertake significant emissions reductions on their own that tangibly reduce the growth of their emissions in the near-term (e.g., to 2020) and lay the foundation for even deeper cuts in the medium-term.

Let's talk (carefully) about climate and population
Have you heard that we're getting new neighbors? Demographers expect that the number of people living on earth - now about 6.8 billion - will grow to between 8 and 11 billion by 2050. Whether population tops out at the high or the low end of those projections will have a huge impact on climate change. So population control is again claiming a place on the environmental agenda.

Counting All the Carbon
Last Thursday, an editorial in the Wall St. Journal referred to a paper in the latest issue of Science entitled, "Fixing a Critical Climate Accounting Error", which concludes that the manner in which the greenhouse gas impacts of biofuels are currently assessed fails to account for significant emissions that occur outside the envelope normally drawn around an ethanol or biodiesel plant and the farms that supply it with feedstock. And if that omission weren't glaring enough, I ran across another instance in which regulators appear to be turning a blind eye to the full impact of another popular option for addressing climate change, electric vehicles.

New MIT Study: Smaller Cuts, If Taken Now, Can Minimize Climate Risk
Even "moderate" cuts in greenhouse gas emissions may be sufficient to avoid the most catastrophic consequences of climate change, says new MIT study. But only if those moderate cuts start now, not in 2020, where many emissions targets take initial aim. Without swift action, even more aggressive cuts may not be enough to stop extreme climate disruption.

Chinese advisor: "2°C is just a vision"
I feel like an idiot for not seeing this one coming from either China or India. It's so painfully obvious, in hindsight, that I have to wonder how anyone who follows energy and environmental issues closely could have failed to predict it. What am I babbling about? China is now saying that the endlessly discussed target of keeping global warming below 2°C is not such a big deal.

Greenhouse gas emissions trading
A recent survey found that there was a significant interest in reducing greenhouse gas emissions, but that investment decisions were made without close attention in the emissions trading scheme market. Rather, investment decisions were guided by expectations about the long term development of overall energy costs.

Is the International Target of 2 Degrees Warming a "Pipe Dream?"
The Sydney Morning Herald reported late last week that research by Australian National University scientist Andrew Macintosh indicates that, based on most industrialized nations' stated mid-term commitments, limiting warming to 2 degrees Celsius simply "won't work."

No sign of break in the link between emissions and higher GDP
An important recent paper looked at the links between economic prosperity and carbon footprint.[1] It compared the average emissions per head in 73 different countries at all different stages in development. Unsurprisingly, it showed that richer countries have much higher greenhouse gas outputs. The interesting and somewhat depressing finding is that a country with 10% higher GDP per head than another will generally have emissions about 8% higher. The correlation is strong - very few countries diverge much from the norm for their level of income.

Geoengineering the Climate: Bad for You and Our Energy Future
Proposals to reduce global warming through giant engineering projects or so-called geoengineering abound. Almost all are in the idea stage. But even if they were ready to deploy today, they would be dangerous for the planet, counterproductive for our energy future and unfair to the public.
