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

december, 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.

Water for food systems and nutrition

december, 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.

Managing soil organic carbon in tropical agroecosystems: evidence from four long-term experiments in Kenya

december, 2022
Kenya

In sub-Saharan Africa, maize is one of the most important staple crops, but long-term maize cropping with low external inputs has been associated with the loss of soil fertility. While adding high-quality organic resources combined with mineral fertilizer has been proposed to counteract this fertility loss, the long-term effectiveness and interactions with site properties still require more understanding.

Uneven ground? Intersectional gender inequalities in the commercialized cassava seed system in Tanzania

december, 2022
Global

Cassava (Manihot esculenta Crantz) is an important crop in Africa, especially to women who rely on it as a household staple food and source of income. In Tanzania, a recent move toward commercializing the cassava seed system resulted in significantly fewer women than men farmers, known as Cassava Seed Entrepreneurs (CSEs), producing improved seed for sale to fellow farmers.

Estimating the potential of spices for mineral provision in a refugee context in East Africa

december, 2022
Global

Micronutrient deficiency remains an enormous problem in refugee settings. Transforming refugees’ food systems through the scaling up of kitchen gardening and fortifying relief food crops with minor food components including nutrient-dense spices can help improve the quality of staple foods. Globally, spices are indispensable in the daily diet and play an important role in the socio-cultural setting of different communities. Forty turmeric and curry powder samples were collected from different market establishments and geographic locations in East Africa.

Satellite-based approach for seasonal rice area and start of season monitoring

december, 2022
Global

Accurate and regularly updated information regarding the cultivated area of rice, along with forecasts and harvested yields, is indispensable for governments in making informed decisions related to food security, natural resource management, agricultural productivity, and insurance. The RIICE technology approach, tailored for Mali's rice-based systems, has demonstrated its capability to intricately map rice areas and accurately determine the start of growing seasons.

Sectoral capacities need strengthening to deliver sufficient tree seed for forest and landscape restoration

december, 2022
Global

The quality and origin of tree seeds and seedlings affect the survival, growth, productivity, ecosystem services and adaptive capacity of restored forests and landscapes. The availability of seeds and seedlings directly influences the delivery of benefits to land users from restoration efforts. Yet, despite more than a decade of global restoration commitments and programmes since 2011, substantial gaps remain worldwide in individual, organizational and sectoral capacities to source and deliver quality tree seeds and seedlings for restoration, especially of native species.

Tailoring Participatory Integrated Climate Services for Agriculture (PICSA) for one-health

december, 2022
Global

In Ghana, AICCRA is implemented by various institutions and NGOs led by the International Institute for Tropical Agriculture (IITA) Benin. As climate information is key in the process, in collaboration with IITA, the Center for International Forestry Research-World Agroforestry (CIFOR-ICRAF/Sahel) is engaged for capacitating stakeholders for the efficient use of climate information and services through the Participatory and Integrated Climate Services for Agriculture (PICSA) approach.

A Review of Evidence on Gender Equality, Women's Empowerment, and Food Systems

december, 2022
Global

Achieving gender equality and women’s empowerment in food systems can result in greater food security and better nutrition, as well as more just, resilient and sustainable food systems for all. This chapter uses a scoping review to assess the current evidence on pathways between gender equality, women’s empowerment and food systems. The chapter uses an adaptation of the food system framework to organize the evidence and identify where evidence is strong, and where gaps remain.
