- Abstract
Groundnut is an important global food and oil crop that underpins agriculture-dependent livelihood strategies meeting food, nutrition, and income security. Aflatoxins, pose a major challenge to increased competitiveness of groundnut limiting access to lucrative markets and affecting populations that consume it. Other drivers of low competitiveness include allergens and limited shelf life occasioned by low oleic acid profile in the oil. Thus grain off-takers such as consumers, domestic, and export markets as well as processors need solutions to increase profitability of the grain. There are some technological solutions to these challenges and this review paper highlights advances in crop improvement to enhance groundnut grain quality and nutrient profile for food, nutrition, and economic benefits. Significant advances have been made in setting the stage for marker-assisted allele pyramiding for different aflatoxin resistance mechanisms—in vitro seed colonization, pre-harvest aflatoxin contamination, and aflatoxin production—which, together with pre- and post-harvest management practices, will go a long way in mitigating the aflatoxin menace. A breakthrough in aflatoxin control is in sight with overexpression of antifungal plant defensins, and through host-induced gene silencing in the aflatoxin biosynthetic pathway. Similarly, genomic and biochemical approaches to allergen control are in good progress, with the identification of homologs of the allergen encoding genes and development of monoclonal antibody based ELISA protocol to screen for and quantify major allergens. Double mutation of the allotetraploid homeologous genes, FAD2A and FAD2B, has shown potential for achieving >75% oleic acid as demonstrated among introgression lines. Significant advances have been made in seed systems research to bridge the gap between trait discovery, deployment, and delivery through innovative partnerships and action learning.

- Abstract
Small-scale cultivation and irrigation of planted forages can increase the availability of good-quality animal feed in smallholder farms. However, low adoption rates of improved forage technologies in most parts of sub-Saharan Africa have been observed and are partly attributed to limited understanding of gender dynamics in the context of production and utilization of planted forages. The introduction of small-scale cultivation and irrigation of planted forages is likely to interlink gender relations in the mixed crop-livestock farming system given the differences in contributions, benefits and challenges men and women farmers face. Efforts to transform livestock systems through improving adoption, scaling, and sustainability forage interventions can benefit from empirical evidence on gender relations in feed-related activities. We aim to highlight the linkage between gender relations and women's empowerment in the production and utilization of feed resources smallholder settings. We used mixed methods, drawing on quantitative data obtained from a cross-sectional survey of 250 men and 250 women, and qualitative data obtained from eight focus group discussions in smallholder settings of the Amhara and Southern Nations, Nationalities, and People's regions of Ethiopia, where small-scale irrigation was introduced to boost the production of cultivated forages by households. We used the Women's Empowerment in Livestock Index tool to elicit data and analyze the empowerment of the sampled men and women. Women's empowerment differed significantly with different dimensions of gender relations, types of forages grown, and small-scale irrigation practice. Moreover, women in households practicing small-scale irrigation of planted forages were significantly more empowered and most (80%) achieved the adequate threshold in "work balance". The study findings point to the positive link between empowerment and the likely shifts in gender relations from the practice of small-scale production and irrigation of forages., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Omondi et al.
