Forests on the move
Studies on ‘natural’ and ‘forced’ migration of forests threatened by climate change. A multi-European project trying to anticipate the effects of climate change on forests is taking shape. In parts of Europe, established forest trees are showing signs of vulnerability – such as drought stress – as their ‘climate niche’ changes. An ambitious long-term project…
Developing crops for mild drought tolerance
Whilst we continue to have no rain in southern England (I’m sure this won’t last too long…), drought tolerance must be on the mind of many farmers. World reports on climate change and food security have identified water scarcity as a critical factor for agriculture this century. Breeding for drought tolerance is a major research…
Climate of changing public opinion
This week is Climate Week in the UK, which aims to get the public involved in thinking about climate change. In the scientific community, there is an increasing level of consensus about climate change and the need to take drastic action to limit severe consequences. However, in order to introduce challenging policies, there must be…
How will climate change affect plant health?
As weather patterns shift around the world due to changing climates, so this brings new challenges to crop protection. Pests and diseases can become a problem in new areas, or appear earlier, making it necessary to change crop protection practices. Conversely, some pests and diseases may become less of a problem as conditions become less…
Cold weather and lots of snow – is this the sign of things to come?
As I watched the news last night, I heard how the current unusually cold temperatures and snow fall in Europe has affected Christmas travelling and the Christmas trade across the continent. Heathrow and Gatwick airports in the UK had to cancel flights, with only one runway operating at Heathrow. Both Paris and Berlin airports had…
Is local food environmentally costly?
Many consumers feel that they should be buying “local food” to help combat climate change – but could “local food” actually result in more carbon emissions than food distributed through conventional supply chains? David Oglethorpe raises this possibility along with some other surprising ideas in a paper in CAB Reviews. Oglethorpe, of the Newcastle…
Climate change – the influence on food security
“When it rains, it does not rain on one roof only” This is a saying from the home village in western Kenya of my friend and colleague Dennis Rangi, CABI’s Executive Director for International Development. He said this in his introduction to the CABI Summit in London which I though was particularly apt as I…
Food Price Hikes – Crisis and Opportunity?
The drastic rises in prices of food during 2007-2008 had severe consequences, but could such rises present an opportunity? Antonio Martuscelli believes “High food prices in the short-run are very damaging for low-income groups of the population in developing countries. At the same time, high prices are an incentive for producers and extremely important for…
Hot Potatoes
With advancing climate change have potatoes had their chips?Looking back over the International Year of the Potato, Marco Bindi (University of Florence) answers the question "What effect will global warming have on the potato?" "Since potato's tuberization rate declines above a temperature of 17°C, increasing temperatures may lead to reduced yields in potato varieties now…
World Food Day – What’s the Point?
Today, October the 16th, is World Food Day. As it was last year. As it will be next year. But, does having a day dedicated to the world’s food security problems do any good? I ask myself.
