    ICARDA a mené cette recherche dans le cadre de la plateforme GENDER (Generating Evidence and New Directions for Equitable Results, en français : Produire des données probantes et concevoir de nouvelles directions en vue de résultats équitables) et de l’initiative du CGIAR De la fragilité à la résilience en Asie centrale et occidentale et en Afrique du Nord. Nous aimerions remercier tous les bailleurs de fonds qui ont soutenu cette recherche par le biais de contributions au Fonds fiduciaire du CGIAR

    Food, land, and water systems face daunting challenges in the future, and the body of research exploring these challenges is growing rapidly. This note is part of a series developed by the CGIAR Foresight Initiative to summarize what we know today about the future of various aspects of food systems. The goal of these notes is to serve as a quick reference, point to further information, and help guide future research and decisions.

    The objective of this research was to determine the effect of cassava (Manihot esculenta Crantz) supplementation on enteric methane (CH4) emissions, carbon footprint, and production parameters in dairy cows. Daily concentrate supply for Jersey and Jersey * Holstein breeds was evaluated in four treatments (T): T1: 100% commercial concentrate; T2: 70% concentrate + 30% cassava leaves; T3: 70% concentrate + 30% cassava roots; and T4: 70% concentrate + 15% cassava leaves + 15% cassava root chips. Measurements of CH4 emissions were performed using the polytunnel technique.

    Extreme climate events such as flood, drought, and high temperature are expected to increase in frequency and intensity with climate change. Mapping and characterization of food production areas at risk can help in better targeting innovations and in enhancing the resilience of affected communities.

    The primary goal of this study was to compare the multiplication rates of yam varieties propagated through organogenesis and somatic embryogenesis (SE). Callus was induced from axillary bud explants of three genotypes of Dioscorea rotundata (Asiedu, Ekiti2a, and Kpamyo) and two genotypes of Dioscorea alata (Swaswa and TDa2014) cultured in Murashige and Skoog (MS) medium containing 9.1 µM 2,4-dichlorophenoxylacetic acid and 5.4 µM naphthaleneacetic acid. Plantlets were regenerated in MS containing 4.4 µM benzylaminopurine and 34 µM uniconazole-P through SE.

    Here, we performed RNA-seq based expression analysis of root and leaf tissues of a set of 24 historical spring wheat cultivars representing 110 years of temporal genetic variations. This huge 130 tissues RNAseq dataset was initially used to study expression pattern of 97 genes regulating root growth and development in wheat. Root system architecture (RSA) is an important target for breeding stress-resilient and high-yielding wheat cultivars under climatic fluctuations.

    The project Reaching Smallholder Women with Information Services and Resilience Strategies to Respond to Climate Change aimed to increase the climate resilience of poor women and men farmers in Africa south of the Sahara and South Asia — especially those in Kenya, Uganda, and India — by overcoming the gendered information gap on accessing climate-smart agricultural (CSA) approaches. The project did this through piloting participatory video-based extension on CSA approaches with more than 30,000 farmers in the three countries.
