“…Of the studies weighted as high and mid, seven of the nine home gardening projects invested in three or more of the types of capital, whereas the seven non-home gardening projects all invested in two or fewer types of capital. Within their human capital investments, seven of the nine home gardening projects incorporated gender considerations into the project, which may have partly been responsible for the positive effect on child dietary intake 13,17 , other improvements in child growth and vitamin A status 4,8 , and morbidity 10,11 .

“…However, the specifics of gender considerations in the above projects were not always presented, and when presented were often limited to making women the intervention target. Some served to empower women and put them in leading roles for implementation, having them reach out to other women in the community 13,18,19 . All seven of the interventions with gender considerations also had inputs into social capital (e.g.…”

Objectives: To review the impact of agriculture interventions on nutritional status in participating households, and to analyse the characteristics of interventions that improved nutrition outcomes. Design: We identified and reviewed reports describing 30 agriculture interventions that measured impact on nutritional status. The interventions reviewed included home gardening, livestock, mixed garden and livestock, cash cropping, and irrigation. We examined the reports for the scientific quality of the research design and treatment of the data. We also assessed whether the projects invested in five types of 'capital' (physical, natural, financial, human and social) as defined in the Sustainable Livelihoods Framework, a conceptual map of major factors that affect people's livelihoods. Results: Most agriculture interventions increased food production, but did not necessarily improve nutrition or health within participating households. Nutrition was improved in 11 of 13 home gardening interventions, and in 11 of 17 other types of intervention. Of the 19 interventions that had a positive effect on nutrition, 14 of them invested in four or five types of capital in addition to the agriculture intervention. Of the nine interventions that had a negative or no effect on nutrition, only one invested in four or five types of capital. Conclusions: Those agriculture interventions that invested broadly in different types of capital were more likely to improve nutrition outcomes. Those projects which invested in human capital (especially nutrition education and consideration of gender issues), and other types of capital, had a greater likelihood of effecting positive nutritional change, but such investment is neither sufficient nor always necessary to effect change.

As colorações amarelo-claro, amarelo-escuro, laranja-claro e laranja-escuro são consideradas desejáveis para consumo humano, uma vez que são mais ricas em betacaroteno (Almeida-Muradian & Penteado, 1992;Hagenimana et al, 1998) e, portanto, apresentam maior valor nutricional.…”

Resumo − O objetivo deste trabalho foi identificar a aptidão de genótipos de batata-doce (Ipomoea batatas) para consumo humano, produção de etanol e alimentação animal, por meio de índices de aptidão. Os índices de aptidão corresponderam às médias dos valores das variáveis padronizadas para 16 características de interesse, ponderadas por pesos atribuídos a cada característica, conforme a aptidão avaliada. Utilizou-se o delineamento experimental de blocos ao acaso, com duas repetições e 39 genótipos: 36 acessos da coleção de germoplasma da Universidade Federal de Lavras e três cultivares comerciais (Palmas, Brazlândia-Branca e Brazlândia-Rosada). Oito genótipos foram considerados aptos à produção de etanol, 11 à alimentação animal e 11 ao consumo humano, incluindo as cultivares Palmas e Brazlândia-Branca. Os acessos UFLA07-12, UFLA07-31, UFLA07-43, UFLA07-49 e UFLA07-53 apresentaram aptidão para produção de etanol, alimentação animal e consumo humano. O índice de seleção é eficiente para estabelecer aptidões para genótipos de batata-doce.Termos para indexação: Ipomoea batatas, biocombustível, índice de seleção, produção de biomassa, produção de ramas, qualidade nutricional. Aptitudes of sweet potato genotypes for fresh consumption, ethanol production and animal feedAbstract − The objective of this work was to identify agronomic aptitudes of sweet potato (Ipomoea batatas) genotypes for fresh consumption, ethanol production, and animal feed, using aptitude indices. The aptitude indices were established as the weighted means of standardized variables for 16 traits of interest, using different weights for each trait according to the evaluated aptitude. The experimental design was a completely randomized block, with two replicates and 39 sweet potato genotypes: 36 accessions of the germplasm collection of Universidade Federal de Lavras (Brazil) and three commercial cultivars (Palmas, Brazlândia-Branca e Brazlândia-Rosada). Eight genotypes were considered apt to ethanol production, 11 to animal feed, and 11 to human consumption, including the cultivars Palmas and Brazlândia-Branca. The accessions UFLA07-12, UFLA07-31, UFLA07-43, UFLA07-49, and UFLA07-53 showed aptitude for ethanol production, animal feed and human consumption. The selection index is efficient in establishing aptitudes for sweet potato genotypes.

“…Each of these studies assessed nutritional outcomes as an indicator of changes in food security, and measured them with comparable instruments. Four of the six studies assessed serum retinol concentration as a proxy for smallholders' nutritional status in South Africa (Faber et al 2002), Mozambique (Low et al 2007;Hotz et al 2012b) and Uganda (Hotz et al 2012a); one in Kenya (Hagenimana et al 1999) observed vitamin A intake; and another in Ethiopia (Akalu et al 2010) examined anthropometric measures such as weight-for-age.…”

The International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding, producing and synthesising high-quality evidence of what works, how, why and at what cost. We believe that better and policy-relevant evidence will make development more effective and improve people's lives. 3ie systematic reviews 3ie systematic reviews examine available high-quality evidence on the effects of social and economic development interventions in low-and middle-income countries. These reviews follow scientifically recognised review methods, and are peer reviewed and quality assured according to internationally accepted standards. 3ie is providing leadership in demonstrating rigorous review methodologies, such as using theory-based designs, for combining different types of evidence suited to respond to the complex and dynamic contexts and challenges of development. 3ie also publishes summary reports based on the full reviews that are designed for use by policymakers and programme managers. About this summary report AcknowledgementsThis review was made possible thanks to the generosity of many individuals and organisations. It was funded by Global Affairs Canada (formerly Department of Foreign Affairs, Trade and Development, Canada), managed through the International Initiative for Impact Evaluation (3ie). 3ie also offered additional financial support for this review. In addition, the Centre for Anthropological Research at the University of Johannesburg generously allocated additional staffing to the review. We would also like to thank our international advisory group and peer-reviewers for their input to this review. ii SummaryThe majority of the rural poor in Africa engage in smallholder farming as a livelihood strategy. At the same time, supporting the practice of smallholder agriculture holds the potential to improve farming households' level of food security as well as local economies in rural areas. Agricultural productivity in Africa stands at one-third to half of global productivity and, although the Green Revolution has rapidly improved social and economic livelihoods in other former developing regions, it is by and large absent from the continent.Programmes that support African smallholder agriculture by implementing training programmes and introducing new technologies and agricultural innovations aim to help release the untapped potential of the African agricultural sector. But we know little about which programmes and approaches are most effective at improving smallholders' food security and economic outcomes. This is the first systematic review of the available research evidence to address this issue. Our objectives were to systematically review the evidence on the effects that training, innovation and new technology have had on African smallholder farmers' economic outcomes and food security. InterventionsThis review assessed the effects of two types of interventions on the livelihoods of Africa...
