TL;DR: In this article, the authors used a mixed methods approach, combining statistical analysis of quantitative data for 456 women with content analysis of qualitative data from in-depth interviews, and found clear signs of increased control by women over food supplies and income, and gains in women's self-confidence and role in the community.
Abstract: There is a lack of scientific evidence that home gardens contribute to women empowerment, which eventually leads to greater gender equality, although it is generally assumed that they do. Using data from poor rural households in Bangladesh, this paper analyzes if and how women’s training in home gardening and nutrition empowers women. The study used a mixed methods approach, combining statistical analysis of quantitative data for 456 women with content analysis of qualitative data from in-depth interviews. The results show that home garden training is popular and widely accepted by both men and women largely because it does not contest existing socially constructed gender roles. Nevertheless, we find clear signs of increased control by women over food supplies and income, and gains in women’s self-confidence and role in the community—as husbands and outsiders begin to recognize their agricultural skills. However, such improvements have been gradual rather than radical. Many men and women appreciated the new opportunity to work together on something of common interest that advanced their quality of life. The evidence presented shows gradual but clear signs of women empowerment as a result of training in home gardens and nutrition.

TL;DR: In this article, the authors found that households benefiting from traditional vegetable promotion and demand creation activities had significantly higher dietary diversity of children under 5 yr and women in reproductive age, while no significant impact of promotion activities on households' dietary diversity.
Abstract: Traditional African vegetables have recently received considerable attention for their contribution to food and nutrition security and opportunities for enhancing smallholder livelihoods. Promoting the production and consumption of traditional vegetables is expected to enhance household nutrition among urban and rural households. The Good Seed Initiative (GSI) program promoted production and consumption of nutrient-dense traditional African vegetables in Arusha region in Tanzania to reduce malnutrition through diet diversification. We estimated the impact of promotion activities on households, women, and children's dietary diversity. The study used cross-sectional data from 258 and 242 households in intervention and control regions, respectively, and applied matching techniques and inverse probability weighting to control for unobserved heterogeneity and selection bias, which could otherwise bias the outcome estimates. We found that households benefiting from traditional vegetable promotion and demand creation activities had significantly higher dietary diversity of children under 5 yr and women in reproductive age. We found no significant impact of promotion activities on households’ dietary diversity. The policy implication is that scaling up promotional and demand creation activities to encourage consumers to grow and eat traditional African vegetables would be an important element in initiatives to increase dietary diversity, particularly for children under 5 and women in Tanzania.

TL;DR: The effects of PMTV on field-grown plants at three locations in the Peruvian Andes where the virus and its fungal vector,Spongospora subterranea, are endemic was examined to examine the response of U.S. cultivars to PMTV infection.
Abstract: The unexpected detection ofPotato mop-top virus (PMTV) in potatoes growing at several locations in the U.S.A. and Canada in 2002 has led to the realization that this soil-borne virus may be widespread throughout the potato-producing regions of both countries. A lack of information concerning the response of U.S. cultivars to PMTV infection caused us to examine the effects of PMTV on field-grown plants at three locations in the Peruvian Andes where the virus and its fungal vector,Spongospora subterranea, are endemic. All 21 U.S. cultivars tested proved susceptible to PMTV infection, especially at La Victoria where the overall incidence of both PMTV and powdery scab was high. Symptom expression in the foliage proved to be an unreliable indicator of virus infection, and thus, more reliable serological (NCM-ELISA) and nucleic acid-based techniques (NASH and RT-PCR) were used to monitor tuber tissue for the presence of PMTV. As much as 25% of field-grown tubers of cvs Kennebec, Monona, and Norland were infected with PMTV, but no correlation between virus infection and either the incidence or severity of powdery scab for any variety was apparent. Although PMTV infection did not result in the appearance of spraing or other internal necrotic reactions resembling those reported from many North American and European locations, a disproportionate proportion of infected tubers did exhibit a reticulate surface cracking. In hydroponic culture, the proportion of cracked tubers increased dramatically when the nutrient solution was seeded with virus-infestedS. subterranea. Comparatively few tubers of cvs Monona and Russet Burbank exhibited this surface cracking, suggesting that these two varieties may be somewhat tolerant to PMTV infection.
