In the past 40 years, a whole supermarket system has been built on the seductive illusion of Permanent Global Summer Time. As a result, a cornucopia of perpetual harvest is one of the key selling points that big stores have over rival retailers. If the enticing fresh produce section placed near the front of each store to draw you in starts looking a bit empty, we might not bother to shop there at all. But when you take into account climate change, the shortages of early 2017 look more like a taste of things to come than just a blip, and that is almost impossible for supermarkets to admit.
Last week the University of Dundee published a new report on Community Resilience to Climate Change, following action research in the Scottish Borders. The team worked with three flood-prone communities in the Scottish Borders – Hawick, Peebles and Newcastleton – to improve understanding and approaches to building climate resilience. By bringing members of the community together with local authorities, policy makers and other stakeholders, they brought about changes to a major flood scheme, increased understanding of the social impacts of climate change and facilitated new flood risk and renewable energy groups. The research also highlighted the important impacts climate change may have on the costs of living which may exacerbate issues for disadvantaged communities.
Agroecology is the science of applying ecological concepts and principles to manage interactions between plants, animals, humans and the environment for food security and nutrition. All over the world farmers already apply this approach, which has a fundamental pillar in traditional and local knowledge. FAO recognizes the importance of farmers managing human and natural capital to improve food security, nutrition, and rural development. Here are some examples of how farmers are acting as the custodians of complex and innovative techniques that, through agroecology, combine local knowledge, traditional products and innovation. Each profile provides a description of the agroecological approach applied in that farm, the challenges faced and impacts of the agroecological solutions.
This document introduces the connections between agriculture and soil biodiversity. Our agricultural activities exert an important influence on the soil biota, their activities and diversity. Clearing forested or grassland for cultivation drastically affects the soil environment and hence reduces the number and species of soil organisms. The reduction of quantity and quality of plant residues and the number of higher plants species leads to a reduction in the range of habitats and foods for soil organisms. Different types of agricultural practices and systems affect the soil biota in different ways and the response may be either positive or negative depending on which part of the soil is affected.
