Showing results for: Crop systems
This book, edited by John Dixon et al., sets out different farming systems used across Africa and their relationships to food security.
Growing millet next to a woody shrub native to West Africa could increase biomass by over 900% compared to growing millet alone, according to this paper. The shrub, Guiera senegalensis J.F. Gmel, has tap roots that can reach water deep in the soil. The study traced the movement of water from the shrub’s deep roots to the millet stems in a simulated drought.
In a paper by FCRN member Johan Karlsson of the Swedish University of Agricultural Sciences, researchers worked together with NGOs to iteratively develop a vision for the future of food production in the Nordic countries. The final vision is based on organic farming and lower meat consumption with livestock fed only on pasture and by-products from food production.
The Food and Agriculture Organisation of the United Nations has released the September 2018 version of its quarterly reports, “Crop prospects and food situation”. According to the report, 39 countries currently require external food assistance, driven by conflicts and climate-related shocks. Of those countries, 31 are in Africa, seven are in Asia, and the remaining one is Haiti. World cereal production in 2018 is estimated to be 2.4% lower than in 2017, which saw a record high.
An Israeli startup has raised $3 million to create a mechanical system for pollinating plants, as an alternative to relying on bees. Wild bee numbers are declining, while bees used by farmers can suffer from Colony Collapse Disorder. Edete Precision Technologies for Agriculture hopes to build two separate systems: one to collect and store pollen, and another to autonomously apply the pollen to plants.
This article looks at our ability to increase cropping intensity in order to meet future food needs and avoid expanding cropped land area. The research produces spatially explicit information on the cropping intensity gap, i.e. the difference between actual and potential cropping intensity and finds that increasing cropping intensity could compensate for land lost to urbanisation.
The U.S. Geological Survey (USGS) has released a worldwide map that details croplands in high resolution in an ongoing effort to monitor croplands and water use.
This paper presents the findings of a food systems model that considers how specific agronomic characteristics of organic agriculture could be harnessed so as to enable it to play a greater role in sustainable food systems.
This new book by Bioversity International summarizes the most recent evidence on how to use agrobiodiversity to provide nutritious foods through harnessing natural processes.
This book explores the potential benefits of Multifunctional Agriculture to the social, economic and environmental sustainability of tropical agriculture and its potential to deliver the new Sustainable Development Goals.
This research brings together data from 389 field trials to determine how the root and shoot biomass, and carbon (C) stocks of major crops correlate to soil C in different environmental conditions. The analysis found all crops allocated more C to their shoots than roots. The greatest C allocation to roots was in grasses (which also had the highest plant biomass production).
This paper, taken from an inaugural edition on planetary health in the Lancet, analyses global food and nutrient production and diversity by farm size, providing evidence on how smallholder farmers contribute to the quantity and quality of our global food supply and discussing the structural impacts of agriculture on nutrient availability.
