In this blog-post Ademola Braimoh, Senior Natural Resources Management Specialist, at the World Bank, argues that quantifying greenhouse gas emissions from agricultural production is a necessary step for climate-smart agriculture (CSA). He writes that greenhouse gas accounting can provide the numbers and data that are important for solid decision making.

The Sustainable Food Trust recently held an event to discuss the question: ‘What role for grazing livestock in a world of climate change and diet-related disease?’

Meat and Livestock Australia (MLA) reports that the Australian beef industry has reduced its environmental footprint over the past 30 years. The results are presented in a new paper in Agricultural Systems, and in a press-release MLA writes that:

Some scientists have suggested that Africa's wet savannahs could be ideal for growing crops needed to meet the growing demand for food and bioenergy. In this paper however, researchers from Princeton University and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) warn that farmland conversion of these savannahs will come at a much higher cost than previously thought.

This updated version further develops the Planetary Boundaries concept, which was first published in 2009.  In their original outline of the concept the authors identified nine key global processes and systems that regulate the stability and resilience of the Earth System – the interactions of land, ocean, atmosphere and life that together provide conditions upon which our societies depend.  They argued that if these natural processes are disrupted beyond a certain ‘boundary’ point, the consequences could be irreversible and lead to abrupt environmental change, making life on earth very hard for humans.

This new study finds that GHG emissions from growing crops and raising livestock are now higher than from deforestation and land use change. It combines three global datasets of greenhouse gas emissions for the 'Agriculture, Forestry and Other Land Uses' (AFOLU) sector. It includes emissions from different sectors and human activities such as deforestation, clearing and burning biomass, and from raising and feeding livestock.

Though politicians and scientists have disagreed about whether atmospheric warming can be delayed by reducing short-lived climate forcing (SLCF) agents, an international research team has confirmed that a reduction in carbon dioxide emissions is the only long-term solution. Previously, politicians and industry had been pushing for measures to reduce SLCF emissions as a way to buy time before needing to address CO2 emissions directly.

A new study from researchers at The Earth Institute of Colombia University and the Woods Hole Research Center says emissions of nitrous oxide could double by the middle of the century if left unchecked. Nitrous oxide is the third biggest contributor to human-induced climate warming after carbon dioxide and methane.

This report, Closing the door on HFCs, documents the continued shift away from hydrofluorocarbons (HFCs) in the supermarket refrigeration sector. Now in its sixth year, EIA’s Chilling Facts reports have become an important resource used to disseminate information about progress in the shift away from HFC-based technology.
