(Re)thinking a different future: sociological perspectives of climate change

It is time to employ some radical thinking on the future of our food systems, write Lexi Earl, Anne Touboulic and Lucy McCarthy The imperative to rethink our food systems to avoid further long-term damage to our climate has never been more pertinent. Yet much of the thinking on the future of food systems is …

Small Islands and Developing States, food systems and climate change

The food systems of Small Islands and Developing States are particularly susceptible to climate change. They therefore require different strategies and thinking on this challenge, argue Ee Von Goh,  Chiew Foan Chin, Christina Vimala Supramaniam, Andrew Clarke, and Pau Loke Show. Small island developing states (SIDS) are disproportionately affected by climate change. SIDS are considered …

Improving farmer livelihoods through better cocoa bean fermentation

We can support small farmers by using science to understand cocoa bean fermentation, ensuring more consistent beans, and better incomes, write David Salt, David Gopaulchan, and Gabriel Castrillo Cocoa is a significant global commodity, generating income, export revenues, and employment for producing countries. Cocoa is grown across the equatorial belt, by some six million smallholder …

Supporting small scale farmers in developing countries

Diversifying agriculture away from limited cereal crops is important for surviving and building resilience to climate change. It also enables small scale farmers to build socio-economic flexibility, and food and nutritional security, argue Sean Mayes and Festo Massawe. Our current reliance on three major cereal crops for 60% of plant-based calories worldwide is risky. Climate …

Surviving drought: The root of the problem in Bambara groundnut

We must pay attention to those parts of plants we cannot see, to fully understand why some plants withstand environmental stress, like drought, better than others, says Kumbirai Ivyne Mateva. Imagine walking out into a crop field. What do you notice? Perhaps you see lush green vegetation swaying ever so majestically in the breeze (Figure 1). …

The nutritional quality of crops and the impact of climate change

Today at COP26, discussions are focused around public empowerment and education in climate action. Galvanising public action is difficult but not impossible. Grace Kangara explains how promoting locally available organic nutrient resources to farmers is key to both improving soils and improving the nutritional quality of crops, ensuring the availability of micronutrient-dense foods at the …

Meeting the protein needs of a growing, and aging, global population with healthy and sustainable protein sources

We need sources of protein that don’t harm human or planetary health, writes Prof Andy Salter. Humans require sufficient supplies of dietary protein, of appropriate quality, to grow and maintain health throughout their lifespan.  Protein quality is dependent on both the amount of essential amino acids contained and its digestibility.  While animal-derived foods represent rich …

The problem of cadmium in cocoa beans

We are identifying ways to produce safer chocolate in order to help small-holder farmers, say David Salt, David Gopaulchan and Gabriel Castrillo Cadmium is a potentially toxic heavy metal that can be found in various foods through bioaccumulation from the soil. It occurs naturally in soils (from volcanic activity, forest fires, and rock weathering), but …

The effects of increasing night time temperatures on plants

It is vital to explore the night time processes of plants to protect our crops from changing climatic conditions, say Prof Erik Murchie and Dr Lorna McAusland The last decade (2009-2019) was the warmest on record. With global temperatures predicted to increase between 2-5 °C over the next 30 years, and more frequent, longer lasting …

Identifying heat tolerant rice varieties to maintain future food security

Rising temperatures are forcing scientists to develop heat tolerant varieties, but this takes time. Policymakers must commit to emissions reductions now, in order to avoid future food insecurity, writes Jordan Robson Global warming is undeniably a huge issue. Average temperatures have been rising steadily since the industrial revolution, and have risen significantly since the 1950s. …
