A Nutrition-Sensitive Agroecology Intervention in Rural Tanzania Increases Children's Dietary Diversity and Household Food Security But Does Not Change Child Anthropometry: Results from a Cluster-Randomized Trial.

This research article published by Oxford University Press, 2021Background There are urgent calls for the transformation of agriculture and food systems to address human and planetary health issues. Nutrition-sensitive agriculture and agroecology promise interconnected solutions to these challenges, but evidence of their impact has been limited. Objectives In a cluster-randomized trial (NCT02761876), we examined whether a nutrition-sensitive agroecology intervention in rural Tanzania could improve children's dietary diversity. Secondary outcomes were food insecurity and child anthropometry. We also posited that such an intervention would improve sustainable agricultural practices (e.g., agrobiodiversity, intercropping), women's empowerment (e.g., participation in decision making, time use), and women's well-being (e.g., dietary diversity, depression). Methods Food-insecure smallholder farmers with children aged <1 y from 20 villages in Singida, Tanzania, were invited to participate. Villages were paired and publicly randomized; control villages received the intervention after 2 y. One man and 1 woman “mentor farmer” were elected from each intervention village to lead their peers in agroecological learning on topics including legume intensification, nutrition, and women's empowerment. Impact was estimated using longitudinal difference-in-differences fixed-effects regression analyses. Results A total of 591 households (intervention: n = 296; control: n = 295) were enrolled; 90.0% were retained to study end. After 2 growing seasons, the intervention improved children's dietary diversity score by 0.57 food groups (out of 7; P < 0.01), and the percentage of children achieving minimum dietary diversity (≥4 food groups) increased by 9.9 percentage points during the postharvest season. The intervention significantly reduced household food insecurity but had no significant impact on child anthropometry. The intervention also improved a range of sustainable agriculture, women's empowerment, and women's well-being outcomes. Conclusions The magnitude of the intervention's impacts was similar to or larger than that of other nutrition-sensitive interventions that provided more substantial inputs but were not agroecologically focused. These data suggest the untapped potential for nutrition-sensitive agroecological approaches to achieve human health while promoting sustainable agricultural practices

Gli effetti dei sistemi agroecologici sui mezzi di sussistenza dei piccoli agricoltori.

Lo scopo della tesi di dottorato è comprendere gli effetti dell'adozione degli approcci agroecologici sul Sustainable Livelihood Framework dei piccoli agricoltori. Sono state adottate tre metodologie di ricerca, revisione della letteratura, meta-analisi e caso di studio, al fine di valutare i benefici derivanti dall'attuazione degli approcci agroecologici sul capitale umano, sociale, naturale, finanziario e fisico. I risultati della tesi hanno mostrato come l’adozione dei sistemi agroecologici possono migliorare i mezzi di sussistenza dei piccoli agricoltori, senza che si verifichino trade-off su una serie di indicatori socio-economici e ambientali selezionati. La tesi evidenzia come i metodi agroecologici possano essere considerati uno strumento praticabile ed efficace per promuovere l’Obiettivo di Sviluppo Sostenibile 1 "Porre fine ad ogni forma di povertà nel mondo" e l’Obiettivo di Sviluppo Sostenibile 2 "Porre fine alla fame, raggiungere la sicurezza alimentare, migliorare la nutrizione e promuovere un’agricoltura sostenibile", in particolare per i piccoli agricoltori con scarse risorse nei paesi in via di sviluppo.The purpose of the PhD thesis is to understand the effects of the adoption of agroecological approaches, both systems and practices, on the Sustainable Livelihood Framework of smallholder farmers. Three research methodologies, literature review, meta-analysis and case study, have been adopted in order to assess the benefits derived from implementing agroecological approaches on human, social, natural, financial and physical capitals. The results of the thesis have contributed to building evidence which demonstrates that agroecological approaches can improve the livelihood of smallholders farmers, without any trade-offs occurring in a wide range of socio-economic and environmental indicators. The thesis highlights that agroecological methods can be considered as a viable and effective tool to promote SDG1 “End poverty in all its forms everywhere” and SDG2 “End hunger, achieve food security and improved nutrition and promote sustainable agriculture”, especially for poor-resource farmers in developing countries

Urban Community Schools: Educator Perceptions of the Effects of Children's Health and Wellness on Learning

Findings from a participatory action-research project that brought together 11 individuals from five of Hartfords seven community schools to engage in a focus group discussion about the effects of childrens health and wellness on learning are presented. The researchers and key personnel from Hartford Public Schools and Achieve Hartford! co-constructed the inquiry. Issues identified as interfering with student learning clustered into themes that include students and family members mental, behavioral, nutritional, and domestic/neighborhood health. The results are being used to create a call for translational research proposals for University researchers to address these questions and disseminate findings to Hartford Public Schools and related community partners

Farming Approaches for Greater Biodiversity, Livelihoods, and Food Security

Scientists and policy-makers globally are calling for alternative approaches to conventional intensification of agriculture that enhance ecosystem services provided by biodiversity. The evidence reviewed here suggests that alternative approaches can achieve high crop yields and profits, but the performance of other socioeconomic indicators (as well as long-term trends) is surprisingly poorly documented. Consequently, the implementation of conventional intensification and the discussion of alternative approaches are not based on quantitative evidence of their simultaneous ecological and socioeconomic impacts across the globe. To close this knowledge gap, we propose a participatory assessment framework. Given the impacts of conventional intensification on biodiversity loss and greenhouse gas emissions, such evidence is urgently needed to direct science-policy initiatives, such as the United Nations (UN) 2030 Agenda for Sustainable Development

Multidimensional Performance of Farming Approaches: A Reply to Mehrabi et al

The letter by Mehrabi et al. [1] provides interesting insights regarding the scientific framework and attitudes needed to support farming approaches for greater biodiversity, livelihoods, and food security. In general, we do not see a dichotomy between our point of view [2] and that put forward by Mehrabi et al. [1]. We share their view that the different farming systems we have described do not form distinct, non-overlapping categories. We do not seek to promote a binary choice between conventional and alternative farming

Does sustainability fit in the EU-Tunisia trade relations? Evidence from the olive oil sector

International audienceTrade agreements between the European Union (EU) and developing countries are often used to promote sustainable development within economic cooperation. The EU-Tunisia trade relations have a long history, starting with the Association Agreement in place and the ongoing negotiations for the new Deep and Comprehensive Free Trade Area (DCFTA) agreement, for further liberalizing the agricultural sector. This study investigates the effects on sustainability of these bilateral relations, with a focus on Tunisian olive oil value chain, considering both the current Free Trade Agreement (FTA) impacts and the future DCFTA agreement expected effects. A two-steps qualitative process consisting of a desk analysis and stakeholders' consultations has been undertaken to report socioeconomic and environmental effects, suggesting policy interventions to be considered within the negotiations framework. Main actions needed encompass an inclusive renovation of Tunisian olive oil sector, a rethinking of exports' tariff quota system to the EU, with special attention to organic olive oil, and water-efficient cultivation systems interventions
