Spatially differentiated nitrogen supply is key in a global food–fertilizer price crisis

Diciembre, 2022
Global

A regional geopolitical conflict and sudden massive supply disruptions have revealed vulnerabilities in our global fuel–fertilizer–food nexus. As nitrogen (N) fertilizer price spikes threaten food security, differentiated responses are required to maintain staple cereal yields across over- and underfertilized agricultural systems. Through integrated management of organic and inorganic N sources in high- to low-input cereal production systems, we estimate potential total N-fertilizer savings of 11% in India, 49% in Ethiopia and 44% in Malawi.

Analysis of adoption of conservation agriculture practices in southern Africa: mixed-methods approach

Diciembre, 2022
Global

In southern Africa, conservation agriculture (CA) has been promoted to address low agricultural productivity, food insecurity, and land degradation. However, despite significant experimental evidence on the agronomic and economic benefits of CA and large scale investments by the donor community and national governments, adoption rates among smallholders remain below expectation. The main objective of this research project was thus to investigate why previous efforts and investments to scale CA technologies and practices in southern Africa have not led to widespread adoption.

Analysing urban and peri-urban youth employment in agribusiness in Malawi

Diciembre, 2022
Malawi

The study aims to analyse key determinants of urban and peri-urban youth employment in agribusiness in Malawi to support youth policies. A mixed-methods approach is used, which combines both quantitative and qualitative analyses. The quantitative method involved a Bivariate Logit Model and Multinomial Logit Model to analyse nationally representative survey data from the Fourth Integrated Household Survey in 2016–2017.

Genetic gains in tropical maize hybrids across moisture regimes with multi-trait-based index selection

Diciembre, 2022
Global

Unpredictable weather vagaries in the Asian tropics often increase the risk of a series of abiotic stresses in maize-growing areas, hindering the efforts to reach the projected demands. Breeding climate-resilient maize hybrids with a cross-tolerance to drought and waterlogging is necessary yet challenging because of the presence of genotype-by-environment interaction (GEI) and the lack of an efficient multi-trait-based selection technique.

The fate of nitrogen during agricultural intensification in East Africa: nitrogen budgets in contrasting agroecosystems

Diciembre, 2022
Global

The intensification of agricultural systems in sub-Saharan Africa (SSA) is necessary to reduce poverty and improve food security, but increased nutrient applications in smallholder systems could have negative consequences for water quality, greenhouse gas emissions, and air quality.

Integrated modeling to achieve global goals: lessons from the Food, Agriculture, Biodiversity, Land-use, and Energy (FABLE) initiative

Diciembre, 2022
Global

Humanity is challenged with making progress toward global biodiversity, freshwater, and climate goals, while providing food and nutritional security for everyone. Our current food and land-use systems are incompatible with this ambition making them unsustainable. Papers in this special feature introduce a participatory, integrated modeling approach applied to provide insights on how to transform food and land-use systems to sustainable trajectories in 12 countries: Argentina, Australia, Canada, China, Germany, Finland, India, Mexico, Rwanda, Sweden, the UK, and USA.

Ground Zero? Let’s get real on regeneration! Report 1: State of the art and indicator selection

Diciembre, 2022
Global

The urgency with which the world needs to combat climate change has led to ambitious commitments by
leading food companies such as Nestlé. Given that a large proportion of emissions in supply chains occur during the
production of commodities, focus has converged on Regenerative Agriculture as a key strategy to achieve
those goals. The Regenerative Agriculture agenda coalesces around three main goals:
• Reduce the Carbon Footprint
• Enhance Soil Health
• Enhance and safeguard Biodiversity

Water for food systems and nutrition

Diciembre, 2022
Global

Access to sufficient and clean freshwater is essential for all life. Water is also essential for the functioning of food systems: as a key input into food production, but also in processing and preparation, and as a food itself. Water scarcity and pollution are growing, affecting poorer populations most, and particularly food producers. Malnutrition levels are also on the rise, and this is closely linked to water scarcity. The achievement of Sustainable Development Goals (SDG) 2 and 6 are co-dependent.
