This book, by Ramesh Ray and S Ramachandran, presents technological interventions in ethanol production from food crops, addresses food security issues arising from bioethanol production and identifies development bottlenecks.
This book, by Klaus Lorenz and Rattan Lal, discusses the present state of knowledge on soil carbon dynamics in different types of agricultural systems, including croplands, grasslands, wetlands and agroforestry systems. It also discusses bioenergy and biochar.
In a guest post for Carbon Brief, Professor Pete Smith of the University of Aberdeen discusses recent research on how climate mitigation through negative emissions could affect biodiversity, through changes in land use. He argues that bioenergy with carbon capture and storage (BECCS) should be implemented sooner rather than later, because of the risk of not meeting climate mitigation targets if BECCS is left until later in the century and because a study estimated that natural land loss could be lower if BECCS is deployed earlier in the century.
The Hoffmann Centre at UK think tank Chatham House has produced a summary of a workshop held in January 2018 on policy implications of widespread deployment of negative emissions technologies. The workshop concluded that bioenergy with carbon capture and storage (BECCS) cannot be used at the scale assumed in emissions pathways compliant with the Paris agreement, because it would cause large land use change in regions of high biodiversity and compete with food production for land. Nevertheless, some BECCS may be needed. Direct air capture would use less land than BECCS, but there are economic and technical barriers.
This book, by Annoula Paschalidou, Michael Tsatiris, Kyriaki Kitikidou and Christina Papadopoulou, identifies the challenges and opportunities surrounding the conflict between food production and energy crop production.
This Research Handbook, edited by Mary Jane Angelo, Fredric G. Levin and Anél Du Plessis, brings together scholars from across disciplines and across the globe (including FCRN member Jonathan Verschuuren) to untangle the climate-food web and critically explore the nexus between climate change, agriculture and law, upon which food security and climate resilient development depends. It is a useful introduction to the research which is being undertaken in the area of climate change and agricultural law.
Using a political-economic approach supplemented with insights from human ecology, this books analyzes the long-term dynamics of food security and economic growth.
This paper by researchers in Germany explores the scalability of managed woody and herbaceous bioenergy plantations (BP) for terrestrial capture of atmospheric carbon. The researchers make simulations to quantitatively explore how much land area could be made available globally for this terrestrial carbon dioxide removal (tCDR) strategy.
This book considers the main links between global conservation of the environment and food production.
This paper describes the operation of a bubble-insulated greenhouse system that recycles organic waste, through its anaerobic conversion into biogas and digestate, into inputs for new food. It reports that commercial crop yields were repeatedly matched and bettered, while an 80% reduction in heat energy demand and 95% reduction in CO2eq emissions was realised compared to conventional greenhouse production.
An engineering project aims to produce food, energy and fresh water from solar power and seawater by using a new combination of already established technologies. The Sahara Forest Project is run in desert areas of Qatar, Tunisia and Jordan.
Biofuel policies have been a major driver of rising prices for biofuel crops around the world, such as rapeseed, corn and soy. In this paper researchers take France as an example and show that a tax of €0.05–0.27 per kg of fertiliser could help to limit French farmers’ use of fertiliser (driven by the high rapeseed prices resulting from biofuels policy).
The neotropical macaw palm (Acrocomia aculeata) is increasingly promoted for large-scale cultivation as a sustainable biomass feedstock in Latin America. This paper warns however that a crucial proportion of areas predicted to be suitable for cultivation are located in areas of high conservational value. The paper also points to climate change scenarios which predict a substantial reduction of suitable areas in coming years.
This paper analyses the options for and impacts of using food waste as animal feed and is the first study to compare the environmental impacts of recycling municipal food waste as animal feed with alternative disposal options in the EU.
The last decade has witnessed major crises in both food and energy security across the world. One response to the challenges of climate change and energy supply has been the development of crops to be used for biofuels. But, as this book shows, this can divert agricultural land from food production to energy crops, thus affecting food security, particularly in less developed countries.
