Learning for food

I-Hsien Porter

Global climate change is likely to cause significant changes, or at least greater uncertainty, in human lifestyles. One vulnerable area of our relationship with the environment is food production.

The BBC recently reported that over the past 25 years, rice yields in Asia have fallen 10 – 20% in response to rising temperatures. This trend is expected to continue. Meanwhile, a summer heatwave (a relatively short-term climatic event) has caused the Russian government to ban the export of wheat, with far-reaching impacts for food prices. In this light, some might be concerned for future food security.

However, many small-scale farmers in the Global South have been dealing with adverse climatic conditions and resource scarcity for decades. In a recent paper in Geographical Journal, Lindsay Stringer and others look to these groups to inform countries in the Global North, which are now facing similar challenges.

Many of the strategies employed by farmers in developing countries were specific to particular places, so had limited transferability to other contexts. As a result, Stringer et al. looked at the process-related aspects of farmer’s experiences, rather than those rooted in place.

Farmers who were faced with adversity were found to have much greater political awareness (e.g. of trade agreements). Those responsible for food production in the developed world could learn from the way that other actors have influenced food and farming policies.

Redefining the traditional North-to-South flow of knowledge into a two-way exchange generates a much larger pool of ideas to mitigate and cope with pressures on food production.
