The Poultry Site – The livestock sector is one of the fastest growing sub-sectors of the agricultural economy, and faces several unprecedented and concomitant challenges, according to the FAO report, Greenhouse Gas Emissions from Pig and Chicken Supply Chain. The sector needs to respond to the increasing demands for livestock products that are arising from population growth and changing consumer preferences. It also has to adapt to changes in the economic and policy contexts, and in the natural environment upon which production depends. At the same time, it has to improve its environmental performance and mitigate its impact on climate.
The Korea Herald – Oceans that grow more acidic through Man‘s fossil fuel burning emissions, can amplify global warming by releasing less of a gas that helps shield Earth from radiation, a study said Sunday.
And the authors warned the potentially vast effect they uncovered is not currently factored into climate change projections.
Scientists say that Man’s carbon dioxide (CO2) emissions contribute to planetary warming by letting the Sun‘s heat through the atmosphere but trapping heat energy reflected back from Earth, so creating a greenhouse effect.

Greenhouse gas emissions from livestock could be cut by up to 30% if farmers adopt better techniques without having to overhaul entire production systems, according to a study released on Thursday by the UN Food and Agriculture Organisation (FAO).
This study is part of a broader research process assessing the local economic, social and environmental impacts from feedstock expansion for the growing biofuel sector. Nonetheless, in the Malaysian context, biofuel production volumes are negligible despite government interest in romoting sector expansion.

Since Malaysia is the second largest palm oil producer in the world, palm oil is slated to become the primary feedstock for biofuel production in the country. Since palm oil consistently outperforms all other substitute vegetable oils on price, it is also becoming an important feedstock globally. While a rapidly growing global biofuel sector could develop into an important new market outlet for Malaysia, it does carry a number of risks. This paper aims to reflect on these risks by exploring the local social and land-use impacts of oil palm in the Beluran District of Sabah State. This is based on household surveys to discover the perception of impacts among relevant local stakeholder groups, and remote-sensing analysis. While the impacts of oil palm in the study site cannot be attributed to the biodiesel industry per se, lessons learnt will be directly applicable to the biodiesel sector in Malaysia, and relevant for the whole Southeast Asia region.

The Guardian – In November 2012, the “big four” professional services firm PricewaterhouseCoopers released a report that concluded it was too late to hold the future increase in global average temperatures to just two degrees Celsius. “It’s time,” the report announced, “to prepare for a warmer world”.
The same month, the World Bank released Turn Down the Heat, which soberly set forth why a four-degree warmer world must be avoided. Meanwhile, accounts of myriad emerging calamities were easy to find in the press: the failure of the Rio+20 talks to result in positive action, “zombie” coral reefs, calls for higher birth rates, declining Arctic sea ice, an approaching “state shift” in the earth’s biosphere, and other evidence of strain in natural systems and of human blindness, ignorance or denial ……..>> Access the complete article<<

Nature – Ecologist Thomas Lovejoy tucks his trousers into his socks with a casual warning about chiggers and then hikes off into the Amazon jungle. Shaded by a tall canopy and dense with ferns and underbrush, the old-growth forest looks healthy, but Lovejoy knows better. Three decades ago, the surrounding forest was mowed down and torched as part of a research project, and the effects have spread like a cancer deep into the uncut area. Large trees have perished. The spider monkeys have moved out, as have the army-ant colonies, and many of the birds that depend on them.

BBC – To the eye, there was nothing remarkable about the aging Falcon 20 jet as it took off from Ottawa International airport in Canada at the end of October in 2012. But the twin-engined, 10-seater plane was in the process of making aviation history.
After a short flight that saw it climb to 30,000 ft (9,000m) over the capital city, the plane touched back down at the airport to secure its world first.

Biomassa & Bioenergia – The Rio +20 emphasized subject that has been much discussed recently by governments. With the inclusion on the agenda of the meeting the topic of renewable energy, the world is forced to discuss viable alternatives and implement effectively in practice initiatives to encourage the use of clean energy sources. The most recent example that has news was the Japan, which has approved a plan to encourage the production of clean energy investment that should result in at least $ 9.6 billion in new facilities with generating capacity of 3.2 gigawatts. Such policy incentives for the production of energy Renewable worldwide have been object of study by KPMG, which raised and compared information subsidies by 15 countries, such as feed-in tariff (mechanism of stimulating the production of renewable energy), Continue reading

Agência FAPESP – Few countries today play a leading role in scientific advances in climate modeling. Most of these countries – the United States, for example – are in the Northern Hemisphere. Australia was the only country in the Southern Hemisphere with this capacity. However, after developing its own climate models for 30 years, the country abandoned its efforts in the area, opting to import and help to improve a model developed by the Hadley Centre for Climate Prediction and Research in Great Britain.
Now, Brazil has filled the void left by Australia, joining the select group of countries capable of developing a model, validating it and simulating global climate changes.
