Towards a low-emission agrifood sector in the People’s Republic of China: A country profile

декабря, 2022
China

The global food system is responsible for 23 – 42% of total net anthropogenic emissions. The food systems of all countries need to be transformed to lower their emissions while producing sufficient, nutritious and healthy food. The Low-Emissions Food Systems (Mitigate+) Initiative aims to offer a comprehensive, evidence-based and holistic approach to reducing agrifood systems emissions. It explores possible pathways that reduce greenhouse gas emissions while enhancing food security and nutrition and livelihoods and preserving the environment.

Institutionalization of the water-energy-food-environment nexus in the Niger Basin

декабря, 2022
Global

In less than one year the Niger Basin Authority, an intergovernmental body tasked with the sustainable development of the Niger waters and associated resources, passed the first ever nexus policy in a transboundary river basin, contributing to a true acceleration of change for improved water and associated development in the Niger River Basin. The guidelines were developed in close collaboration with the nine basin countries and complemented by a large capacity building program.

Optimizing sparse testing for genomic prediction of plant breeding crops

декабря, 2022
Global

While sparse testing methods have been proposed by researchers to improve the efficiency of genomic selection (GS) in breeding programs, there are several factors that can hinder this. In this research, we evaluated four methods (M1–M4) for sparse testing allocation of lines to environments under multi-environmental trails for genomic prediction of unobserved lines.

Performance and stability of improved cassava (Manihot esculenta Crantz) clones in demand creation trials in Nigeria

декабря, 2022
Nigeria

Cassava fresh root yield and dry matter content constitute major determinants of demand by end-users. Increased demand for the seeds of improved varieties will facilitate the development of a sustainable seed system. However, for wide acceptability, there is a need to continuously evaluate candidate varieties for stability across different agroecological zones. Participatory Demand Creation Trials (DCTs) were established to evaluate cassava varieties with farmers and processors utilizing the best agronomic practices.

Harnessing indigenous knowledge and practices for effective adaptation in the Sahel

декабря, 2022
Global

The Sahel region of West Africa has experienced some of the most severe multidecadal rainfall variability over the past 50 years. Based on recollections of the past and observations of the present, local communities in the Sahel have developed extensive knowledge and understanding of their environment and climate that enables them to harness ecosystem services to support their livelihoods and survive environmental changes.

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

декабря, 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.

Multicriteria assessment of alternative cropping systems at farm level. A case with maize on family farms of South East Asia

декабря, 2022
Global

CONTEXT: Integration of farms into markets with adoption of maize as a cash crop can significantly increase income of farms of the developing world. However, in some cases, the income generated may still be very low and maize production may also have strong negative environmental and social impacts.

Introducing the non-rancidity trait into pearl millet seed : scenarios for achieving future impact in Kenya

декабря, 2022
Kenya

The International Maize and Wheat Improvement Center (CIMMYT) and partners are working to apply CRISPR technology to achieve a step-change in pearl millet seed product design: altering fatty acid metabolism to achieve the non-rancidity trait to create grain that when milled into flour has extended shelf life. Kenya is a country where the regulatory environment permits the introduction of gene-edited seed products when derived from site directed nuclease 1 and 2 derived technologies.

Do rice farmers have knowledge of greenhouse gas (GHG) emission mitigation strategies? New evidence from Nigeria

декабря, 2022
Nigeria

In Nigeria, rice remains a major staple food source for the rapidly growing population of an estimated 210 million people. However, traditional rice production carried out in flooded soil is associated with greenhouse gas (GHG) emissions, mainly anthropogenic methane (CH4) and nitrous oxide (N2O) in Nigeria. Both CH4 and N2O are harmful GHGs that raise the temperature of the planet by retaining heat in the atmosphere.

Urochloa humidicola breeding: Selection based on hybrid performance in multi-environmental trial on Bh22 population

декабря, 2022
Global

In 2022, a new cohort of U. humidicola hybrids was obtained and named Bh22. This cohort was composed of 5,024 hybrids and corresponded to the 3rd cycle of recurrent selection. Out of 5,024 individuals tested, 1,887 were identified as apomicts through the molecular marker p779/p780 (Worthington, 2016). In 2023, with the objective to select i) a subset of genotypes based on their performance and ii) mothers based on hybrid performance, a multi-environment trial was implemented.

Gender equality and women’s empowerment in rural transformation: From evidence to public action

декабря, 2022
India

The slow, limited, and uneven progress on women’s empowerment and gender equality over the last decade clearly shows that rural transformation, with its focus on efficiency and productivity, is leaving women behind in addition to having negative impacts on the environment and nutrition. New inclusive models of rural transformation are called for. The study argues that treating gender equality and women’s empowerment as key in the process of rural transformation will lead to a more inclusive and resilient transformation of rural spaces.
