This Nature Plants paper by researchers from agroecological and agronomical research institutions in France used a statistical modelling approach to predict the effects of reducing pesticide use on the productivity and profitability of French arable farms.
A recent paper published in BioScience articulates the need for a new vision and new goals for the sustainable intensification of agriculture, moving away from the often cited statement that food production must double by 2050 to feed the world's growing population.
This paper examines high-resolution, crop-specific GHG emissions and GHG intensity estimates which are derived using a method that couples biophysical models with novel 5-arc-minute resolution data.
This article by agricultural researchers in Spain reviews the historical changes in land use and soil management practices, and examines how these changes have contributed to soil erosion in the past, before presenting modelling data to show how soil erosion may impact on agricultural yields in the future.
This paper takes as its starting point the mainstream projections that in future, global food production will need to increase by another 60–110% by 2050, to keep up with anticipated increases in human population and changes in diet (it should be noted, however, that the need and feasibility of such increases is contested (see), with many arguing that dietary change and waste reduction can reduce the need for production increases (see)).
This report highlights the impacts of climate change on the agricultural sector and how, in the future, this is increasingly threatening food security for millions. The report states that meeting the goals of eradicating hunger and poverty by 2030, while addressing the threat of climate change, will require profound transformation of food and agriculture systems worldwide – which is of course a major challenge.
The ‘2016 Food, Water, Energy and Climate Outlook’ by the MIT Joint Program on the Science and Policy of Global Change finds that even if commitments from the COP21 climate agreement are kept, many staple crops in various regions are still at risk of crop failures through extreme events, but at the same time, yields in many regions are projected to increase.
The agricultural sector is particularly vulnerable to climate change; a small increase of 1 degree Celsius can have significant negative impacts on crop yields, especially in the tropics. Global economic losses in production of three major crops (wheat, maize, and barley) attributed to climate change in the recent past are estimated at approximately US$5 billion per year.
The need to make the best use of agricultural land in the face of growing future demand has made sustainable intensification an important area of food systems research. Previous research which focused on this topic, looked at the spatial distribution of the intensity of agricultural production and how this has changed, but according to the authors, did not provide sufficient insight into the drivers of intensification patterns, especially at subnational scales.
In the paper Organic agriculture in the twenty-first century by Reganold and Wachter (2016), that the FCRN has previously summarised, organic agriculture was found to be more profitable and environmentally beneficial compared with conventional farming as well as more productive and profitable in the long term, especially in developing countries where it provides an “ideal blueprint in addressing climate change”.
According to the latest joint OECD-FAO report Food Outlook which analyses global food markets, the coming decade will likely see an end to a period of high agricultural prices, although prices are expected to rise for livestock relative to those for crops.
Taking as their starting point a hypothetical zero-deforestation for agricultural production, where people would refrain from clearing any further forests for agricultural purposes, the researchers behind this study look at both supply side and demand side measures to assess how changes in production and diet can assist in halting deforestation
More than three-quarters of the world's food crops are at least partly dependent on pollination and in many regions over 40 percent of the bees and the butterflies are threatened with extinction, according to a new report entitled Thematic Assessment of Pollinators, Pollination and Food Production.
This article in Nature Climate Change titled Cropping frequency and area response to climate variability can exceed yield response, suggests that previous studies may have underestimated the impact of climate change on the world’s food supply.
