Understanding the genetic and molecular function of nitrate sensing and acquisition across crop species will accelerate breeding of cultivars with improved nitrogen use efficiency (NUE).
Here, we performed a genome-wide scan using wheat and barley accessions characterized under low and high N inputs that uncovered the NPF2.12 gene, encoding a homolog of the Arabidopsis nitrate transceptor NRT1.6 and other low-affinity nitrate transporters that belong to the MAJOR FACILITATOR SUPERFAMILY.

Agriculture faces the competing challenges of enhancing productivity and raising the incomes of smallholder farmers, while simultaneously also addressing concerns related to environmental sustainability. Digital technologies have the potential to tackle these challenges and transform agri food systems in unprecedented ways. This policy brief advocates for the conceptualisation and development of digital public infrastructure for agriculture for a more equitable and responsible development pathway for agriculture in the G20 countries.

Rainfed agriculture is at the centre of many West African economies and a key livelihood strategy in the region. Highly variable rainfall patterns lead to a situation in which farmers’ investments to increase productivity are very risky and will become more risky with climate change. Process-based cropping system models are a key tool to assess the impact of weather variability and climate change, as well as the effect of crop management options on crop yields, soil fertility and farming system resilience and widely used by the West African scientific community.

Are the forest conservation practices sustained after Payment for Environmental Services (PES) programmes end? Using a sample of 268 (former) PES recipients and non-recipients from the Budongo-Bugoma PES programme in Western Uganda, we employ the before-after-control–intervention (difference-in-difference) approach to estimate the PES programme outcome on their privately owned forests. PES is associated with less deforestation during the operational period, but the link has vanished four years after programme termination.

Cassava (Manihot esculenta Crantz) is a predominant food security crop in several developing countries. Its storage roots, rich in carbohydrate, are deficient in essential micronutrients, including provitamin A carotenoids.
Increasing carotenoid content in cassava storage roots is important to reduce the incidence of vitamin A deficiency, a public health problem in sub-Saharan Africa. However, cassava improvement advances slowly, mainly due to limited information on the molecular factors influencing β-carotene accumulation in cassava.

Present global maps of soil water retention (SWR) are mostly derived from pedotransfer functions (PTFs) applied to maps of other basic soil properties. As an alternative, ‘point-based’ mapping of soil water content can improve global soil data availability and quality. We developed point-based global maps with estimated uncertainty of the volumetric SWR at 100, 330 and 15 000 cm suction using measured SWR data extracted from the WoSIS Soil Profile Database together with data estimated by a random forest PTF (PTF-RF).

The International Center for Agricultural Research in the Dry Areas (ICARDA), The Amhara Regional Agricultural Research Institute (ARARI), the Accelerating the Impact of CGIAR Climate Research in Africa (AICCRA), and the Amhara Livestock and Fisheries Resource Development Office organized a workshop that took place on May 29, 2023, in Bahir Dar Ethiopia.

The One CGIAR Research Initiative on “Rethinking Food Markets and Value Chains for Inclusion and Sustainability” commissioned a meta-study to review the available evidence and to identify knowledge gaps regarding the impacts on employment in agrifood value chains (AVC) integration and modernization processes in developing countries. This review included 290 texts, mostly journal articles, but also book chapters and reports.

Accurate estimates of habitat extent and rates of change are crucial inputs for the global, regional, and national assessments that guide policy-making and prioritize strategies. This can contribute to an understanding of ecosystems in the landscape for their use, management, and preservation. Mangroves are one of the types of ecosystems in which estimation discrepancies have been analyzed to determine the impacts of data quality on conservation and policy-making.

This policy brief sheds light on the incentives that can promote deforestation-free cocoa production in Colombia. It proposes steps that decision-makers can take to support Colombia’s vision of a zero-deforestation cocoa supply chain.

This report was prepared by CGIAR in response to an invitation from the Secretariat of the FAO Commission on Genetic Resources for Food and Agriculture. It is structured to correspond, in general, to agenda items 2-11 of the Nineteenth Regular Session of the Commission on Genetic Resources for Food and Agriculture (CGRFA-19). Some sections of this report were previously included in the CGIAR submission to the Eleventh Session of the Intergovernmental Technical Working Group on Plant Genetic Resources (ITWG-PGRFA-11), in April 2023.

In order to safeguard countries from quarantine risks (insect pests, pathogens, nematodes, parasitic weeds) associated with the movement of legume (faba bean, lentil, chickpea, grasspea) and cereal (wheat and barley) germplasm, ICARDA’s Germplasm Health Unit (GHU) follows a regulatory and quarantine program implemented in close collaboration with competent institutions where ICARDA has platforms for crop breeding, germplasm multiplication and evaluation and genetic resources exchange.
