The Pig Site – A study at Leeds University in the UK shows it is important for farmers to provide outdoor sows with methods to keep themselves comfortable throughout the year and, crucially, not only during the summer months. Painting outdoor huts white and insulation help to keep sows both comfortable and productive, while wallows and sprinklers need to be provided early in the year and throughout the summer months … Continue Reading

The CROP Site – The purpose of this post is to derive the biodiesel supply curve from the relationships first presented in the September 25 post.
We begin by reviewing the main results of that earlier post. Figure 1 shows a scatter of monthly biodiesel production and net returns above variable costs for each calendar year between 2010 and 2013. Monthly biodiesel production is estimated by the EIA and monthly biodiesel net production returns above variable costs are based on a model of a representative Iowa biodiesel plant (see the post here).
A best-fit regression line is also shown for each year, with the natural log (ln) of production used as the dependent variable. The data are divided by calendar years because in years when the blenders tax credit is not in place (2010 and 2012) there is little relationship between biodiesel production and returns. Basically, production in these years is “stuck” at the RFS biodiesel mandate regardless of the level of returns.
In the other years (2011 and 2013) market participants expect the credit to expire at the end of a calendar year, so there there is an obvious incentive for blenders to bid up the price of biodiesel in order to increase production and take full advantage of the credit before it expires. In essence, the unusual market circumstances in 2011 and 2013 provide a unique opportunity to identify a biodiesel supply curve even with a seemingly binding RFS mandate in place…>>Continue Reading<<

Agência FAPESP - The increases in temperatures and changes in the rainfall regime due to global warming that are forecast for several regions of Brazil could significantly impact agriculture in the country. Crops such as beans, soy, wheat, and maize will be particularly affected, according to studies by the Brazil Global Climate Change Research Network (Rede Clima).
By cross-referencing the models of the Intergovernmental Panel on Climate Change (IPCC) and Brazilian regional models, researchers at Rede Clima analyzed the expected impact of climate change on national crop-growing areas.
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.
The Korea Herald - Crop-damaging insects, bacteria, fungus and viruses are moving poleward by nearly 3 kilometers each year, helped by global warming, a study said.
A team at Britain’s University of Exeter trawled through two huge databases to chart the latitude and dates for the earliest record of 612 crop pests.
Since 1960, these pests have been heading either northwards or southwards at a rate of around 2.7 kilometers yearly.

Agência FAPESP – Universidade de São Paulo researchers have published a detailed map of atmospheric pollution, showing that the countries with the worst air quality indices are precisely those with the fewest scientific production on this topic. The article was published in the August edition of Nature Reviews Cancer.
In the opinion of the article’s author, Lais Fajersztajn, lead researcher of the FAPESP-funded study, the result indicates that science is an important tool for improving atmospheric pollution and must be strengthened in developing countries through international collaboration. “The greater the knowledge, the better it is disseminated, and the more chances there are of dealing with the problem,” she stated.

Agência FAPESP – The deforestation and burning of the Amazon and interactions between the Atlantic Ocean and the atmosphere are some of the Brazil-specific climate issues that the Brazil Earth System Model (BESM) takes into consideration to address climate change better than the world’s existing models.
The model was presented in detail on September 9 at the opening of the First National Global Conference on Climate Change in São Paulo.
FAPESP - Brazil is the largest producer of ethanol from sugarcane in the world and occupies the leadership in technology for its production. The advances in technology have meant that its productivity is outstanding and the costs of production much lower than those of its international competitors. This leadership is due to the long work of many years undertaken by researchers in institutions of higher education and research and in private enterprises, which has resulted in a valuable baggage of knowledge and technology on sugarcane and its derivatives and on the process of ethanol manufacture.

The Korean Herald – A group of South Korean scientists has developed a new and much more advanced material that can capture carbon dioxide, and at a significantly lower price, the science ministry said Friday.
Using nano particles, the team from Seoul’s Hanyang University has developed a new membrane that can specifically capture only carbon dioxide or other molecules of different sizes if necessary, according to the Ministry of Science, ICT and Future Planning.
