Here’s an interesting synopsis of global initiatives by UN Secretary-General Ban Ki-moon from a speech delivered to Sydney University on September 8th. How/to what extent the aspirations are fulfilled, of course, is key, but the aims are impressive. The Secretary General was seeking to counter the common belief that countries around the world are hamstrung in their attempts to mitigate climate change. He pointed to some good news, while also being clear about the long road ahead. The entire speech can be found here.

China has pledged to reduce its carbon intensity by up to 45 per cent in the next decade. It now produces half of the world’s wind and solar equipment and is growing its capacity rapidly. It has already surpassed the United States to lead the world in installed clean-energy capacity. The European Union has committed to cut emissions by at least 20 per cent of 1990 levels by 2020, regardless of what actions other countries take. The European Union’s commitment has not wavered, even in the face of tough economic times.

Mexico has launched a plan to reduce 51 million tons of carbon dioxide next year alone. That’s equal to four-and-a-half years of pollution from all the vehicles in Mexico City. Korea devoted 80 per cent of its stimulus programme to green growth, an investment that stands to deliver major economic, as well as environmental, benefits. India is also in the race, planning to increase investment in the clean energy sector by more than 350 per cent in this decade.

Japan is aiming to create 1.4 million new green jobs. Denmark is moving to be free of fossil fuels by 2050. Brazil committed to reducing its deforestation rate by 80 per cent by the year 2020 and is years ahead of schedule – even as it also continues to prove renewable energy can power a major economy.

It’s not your everyday, run of the mill design problem. But it is an everyday reality – cows produce significant amounts of the greenhouse gas (GHG), methane, and concentrated animal feeding operations (CAFOs) are therefore point sources of GHG pollution. There are arguments for ending the CAFO practice, but these controversial land uses appear to be with us for the foreseeable future anyway. Can the impacts be mitigated? Can agroforestry techniques be used to mitigate the emissions, and, if you plant a lot of trees, do you still have enough open land to maintain farm functionality? These are the questions asked by the ESF graduate student, Au Ta, in his capstone project, supervised by Dayton Reuter and me. His study produced some very interesting results.

Forested buffer alternatives were tested

Graduate students in landscape architecture programs sometimes produce studies that are worthy of peer-reviewed publication, but these projects often remain hidden in their respective departments. As a discipline, we need to move toward the expectation that this work will be published, either in traditional print media or through online journals. Our colleagues in other disciplines would not squander these resources! Like many LA graduate theses and capstones, Au’s project was not designed from the outset to be a carefully controlled study, but instead evolved over time into something interesting, thought-provoking, and not necessarily easy to publish in science journals because of the degree of intuitive design involved. But the project is well-crafted and reaches some surprising conclusions. Click continue reading to read the abstract and get a link to the entire paper. (more…)
