This perspective article exposes and explains uncertainties in our historical calculations of carbon fluxes associated with land use and land cover change, and uses comparisons between dynamic global vegetation models (DGVMs) to estimate the effects of these uncertainties on historical, current and future assessments of carbon fluxes between the land and air.
This is a new book on the concept of sustainable intensification in the context of smallholder agriculture.
This paper argues that the strength of the linkages between the ‘Human System’ and the Earth system warrants a new paradigm of modeling which incorporates key factors in one system as variables of a model of the other.
This newly revised edition by Cambridge researchers sets out to help those interested in evidence-based conservation with summaries of relevant topics.
Tara Garnett participated in the Nobel prize celebrations, giving the opening speech the Nobel Week Dialogue event in Stockholm on 9 December. You can watch her talk, introducing the day's discussion here.
FCRN member Colin Sage from University College Cork, Ireland, is co-editor of this book. The following information was provided:
Opponents in an academic discussion on the relevance and the validity of the ‘Ecological Footprint approach’ have come together to write an article in which they challenge each other’s views.
This paper by researchers in the US and Australia reports the findings of a long-term field-trial-based investigation into the effect of elevated carbon dioxide concentrations (CO2) on soy yield and drought tolerance. Their findings challenge the widely-held belief that crop yield will be increased by elevated CO2 (the so-called CO2 fertilisation effect) both because of increased photosynthetic rate, and because of lower susceptibility to drought: it has long been assumed that in higher CO2 conditions, stomatal conductance will be lower, leading to slower water loss from the leaves, slower water uptake from the roots, and consequently more moisture remaining in the soil for longer, thereby sustaining crops in limited rainfall.
This is the first of a series of videos explaining the basic facts about climate change, its causes and consequences. It is produced by GreenFacts , an organisation dedicated to publishing accessible and peer-reviewed summaries of major international scientific documents independent experts.
In a new video published by the Royal Society in their 'Science stories' series (which charts 350 years of scientific publishing at the Royal Society) Dr Paul Williams, a meteorologist in NERC's National Centre for Atmospheric Science at the University of Reading, considers why it is that scientific questions so often turn into full-blown and acrimonious controversies.
This paper describes how deep public divisions over climate change are unrelated to differences in how well ordinary citizens understand scientific evidence on global warming. Contrary to what many believe, members of the public who score the highest on a climate-science literacy test are the most politically polarized on whether human activity is causing global temperatures to rise.
This commentary in the Nutrition and Cancer journal discusses some of the concerns related to the promotion of “miracle foods” by the media. The recommendation made in the study is that nutritional scientists and epidemiologists should be cognizant of the public health messages that are taken from their individual studies and not sensationalize the findings of a single study.
The CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) has launched the “Big Facts” website, a set of 30 facts integrating research on topics that include food demand, agricultural emissions, climate impacts, adaptation, and mitigation.
A new 'Farm Platform' has been launched at Rothamsted Research North Wyke in Devon, aims to help farmers to optimise productivity in ways that are sustainable, whilst at the same time understanding the impact of farming methods on the environment.
In 2009, Rockström et al published a paper in Nature which proposed the concept of nine planetary boundaries, which we must keep within if we are not to suffer potentially catastrophic consequences. More recently Nature has published an interesting opinion piece on the boundaries idea.
Carbon dioxide and global climate change are largely invisible, and the prevailing imagery of climate change is often remote (such as ice floes melting) or abstract and scientific (charts and global temperature maps). Using visual imagery such as 3D and 4D visualizations of future landscapes, community mapping, and iconic photographs, this book demonstrates new ways to make carbon and climate change visible in our own backyards and local communities.
