The authors behind this study say that climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years.
This study looks at the double challenge of increasing food security while addressing environmental problems caused by agriculture. It identifies a set of key actions in three broad areas that hold the greatest potential for achieving these efficiency and sustainability goals.
Collaborating with Asda, Sainsbury’s, Nestlé, AB Agri, Yara, BASF, BOCM Pauls, Volac and the NFU and CLA, the University of Cambridge’s Institute for Sustainable Leadership has produced a report entitled The Best Use of UK Agricultural Land which considers how to best manage the 35% difference they projected between the supply and demand of available land.
This report from the Institution for Mechanical Engineers discusses the role that cold chain technologies can play in improving food security in developing countries. It argues that we need to address the question of how we can achieve sustainable food security and not just increased production.
This paper critiques the concept of sustainable intensification as follows: “Though often lauded by scientists and policy makers alike as a panacea to the mass environmental degradation that accompanies typical food production processes, the authors find that ‘sustainable intensification’ is actually highly unsustainable as it fails to consider the long run social, economic and ecological consequences of intensified production. Thus the authors aim to redefine the scope of the discourse, moving beyond simple calls for increased production capacities to instead enmesh food security within a more holistic approach to development which requires better governance, more empowerment, and greater access and fairer distribution of food within more resilient food systems. Ultimately, sustainable intensification is rendered worthless if those facing dire food insecurity remain unable to access the yields of increasing production.“
This study calculates that crops grown on land obtained through large scale acquisitions in developing countries could potentially feed 100 million more people than current practices do today.
This paper investigates whether current yield trajectories are adequate to achieve the production increases that many forecasts suggest are needed on existing farmland. The results indicate that the majority of global cereal crops such as rice, wheat and corn may have reached their maximum possible yields. Six statistical models were analysed to identifying the most appropriate shape of historical yield trend and the analysis makes it possible to estimate in which countries and regions yields are flat, rising, declining or plateauing.
This report by Swedish International Agricultural Network Initiative SIANI, deals with potential ways of feeding the projected world population of 9.6 billion in 2050 by sustainably closing yield gaps.
The EU Gratitude project is aiming to reduce waste from post-harvest losses of root and tuber crops and turn unavoidable waste into something of value. It has yielded interesting findings on how waste from cassava and yams is managed in the value chains, findings which challenge the conventional idea that waste and losses in developing countries occur at the farm end of the value chain. In fact the results, presented at the mid-term review meeting, showed that in Ghana in particular waste and losses were greater at the consumer end and hence more costly- these patterns are more similar to those found in developed countries than previously believed.
This IFPRI (International Food Policy Research Institute) policy note summarises the results of a study that compares the effects that different technologies have on crop yields and resource use, in particular arable land, water and nutrient inputs. It models technology-induced changes in crop yields and considers how the mix of technology uptake can influence the global food market through changes in food prices and trade flows, as well as calorie availability, in particular for developing countries.
