Agricultural production sits at the heart of major societal concerns, spanning food security, nutrition and health; livelihoods and development; the environment;and animal ethics. In early history, the farming of domesticated species created food surpluses that allowed for the development of sedentary civilisation. Later, the Green Revolution of the twentieth century allowed for large groups of people, especially in developed countries, to “move off the land” and improved food supplies across much of the world. Yet while innovations in modern agronomy, plant and animal breeding, pesticides and fertilizer use have greatly increased food output, much environmental harm arising from these practices has occurred while concerns are also growing around excess calories and poor nutrition, leading to obesity and associated non communicable diseases as well as micronutrient deficiencies. Many of the 1.3 billion people worldwide who rely directly or indirectly on agriculture for their living face problems arising from imbalanced power structures, including poor working conditions, uncertain land use and tenure, and lack of access to inputs, infrastructure, capital and knowledge; these imbalances play out along the whole of the food value chain, between the genders, within country populations and across countries and regions. As to the environment, agriculture is responsible for some 20% of global anthropogenic greenhouse gas emissions of which about half arise directly from crop and livestock production and the other half from agriculturally induced land use change. It is also the main cause of deforestation and biodiversity loss, a major user and polluter of scarce water resources and responsible for the disruption of global nitrogen and phosphorus cycles.
This paper reviews studies where changes in both productivity and species richness have been tracked at the same location, following changes in the intensity of land use. On average, intensifying land use leads to a 20% gain in output and a 9% decrease in species richness, but there is considerable variation between different contexts.
Cellular Agriculture UK - a hub for the cultured meat sector in the UK - has created a database of people who are based in the UK and who have a professional interest in cellular agriculture.
This book, edited by Mette Vaarst and Stephen Roderick, reviews key challenges and solutions in improving the health and welfare of organic farm animals, including case studies from organic farming of dairy and beef cattle, sheep and goats, pig and poultry.
This paper provides an assessment of the environmental impacts of converting waste streams from the food industry into products such as fertiliser, pet food, livestock feed or feed additives using the larvae of Hermetia illucens, the black soldier fly.
This paper shows that pollinator services in agricultural landscapes that have been highly altered from their natural state are lower than would be predicted from a simple count of pollinator species. The paper bases its estimates on a study of the evolutionary relationships between pollinators and extensive surveys of pollinators.
This paper assesses the agricultural water use efficiency of different food types based on their nutrient content, instead of the conventional approach of assessing water use in terms of litres used to produce a certain weight of food. The purpose of the study is to determine whether higher intakes of nutrient-rich foods such as fruit, vegetables and seeds might conflict with the aim of minimising agriculture’s water use.
In this research on the Brazilian Amazon, FCRN member Erasmus zu Ermgassen of UCLouvain finds that forest conservation and agricultural growth are not mutually exclusive, and sheds new light on the land sparing/sharing debate. The authors argue that enforcement of Brazil's forest laws is key to encouraging the efficient use of land and the sustainable development of the agricultural sector.
This book explores the economic, environmental and social aspects of the development of Brazil’s agricultural sector over time. Chapter topics include the role of public policies, innovation and research, family farming and land governance.
This book discusses resilience in agriculture, using economic, ecological and sociological perspectives. Topics covered include biodiversity, ecosystem services, land sparing versus land sharing, and sustainable intensification.
This report from the FAO reviews the state of ‘biodiversity for food and agriculture’, i.e. any biodiversity that contributes in some way to food production. It finds that 26% of livestock breeds are at risk of extinction. Crop diversity is declining, with only 9 crop species accounting for 66% of crop production. One third of fish stocks are overfished, and a further 60% are being fished at their maximum sustainable capacity.
This commentary from the US-based Breakthrough Institute argues that agroecology is not the best way of reforming agriculture in Africa, because most African agriculture already follows agroecological principles such as avoiding monocropping and not using much fertiliser or pesticide.
This booklet, by FCRN member Imke de Boer, sets out the scientific basis for the 2018 Mansholt lecture by Louise Fresco, President of the Wageningen University & Research Executive Board. The lecture discussed how the concept of circularity can be applied to agricultural production.
This paper uses long-term studies from Europe and China to examine the effects on soil quality of organic matter addition, no-till practices, crop rotation and organic farming. It finds that yields are lower under no-till and organic practices, but that these practices are associated with higher soil organic matter.
This paper, by researchers from the University of Oxford’s LEAP project, models the climate impacts of beef cattle and cultured meat over the next 1000 years using a climate model that treats carbon dioxide, methane and nitrous oxide separately, instead of using the widespread Global Warming Potential, which assigns a CO2-equivalent value to each greenhouse gas according to warming caused over a specified timeframe.
