Through an analysis of survey data collected from 518 households living around the town of Eldoret, Kenya, we investigate the existing links between peri-urban households’ engagement in agriculture, their dietary behaviour, and their children’s nutrition outcomes. We find that peri-urban households engaged in agriculture, particularly in crop growing and in the sales of their agricultural produce, have more diverse and nutritious diets than agriculturally non-engaged households, all other things being equal. However, a significant improvement in children’s health outcomes is observed in these households only when coupled with improved water, sanitation, and hygiene conditions.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 5","pages":"1235 - 1263"},"PeriodicalIF":5.6,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01475-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142182958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As multistakeholder governance approaches become increasingly common, significant concerns have been raised about their ability to deliver such change. Such concerns are based on case study findings repeatedly highlighting their susceptibility to corporate capture. This study goes beyond individual case studies, examining global multi-stakeholder initiatives (MSIs) whose stated aim is to drive a healthier and more sustainable food system. It identified and categorised actors within these MSIs, drawing on social network analysis to provide insights into actor centrality, power structures, and how this might impact MSIs’ potential to drive transformative change. Thirty global MSIs were included in our sample, including a total of 813 actors. Most actors were based in high-income countries (HIC) (n = 548, 67%). The private sector (n = 365, 45%) was the most represented actor category, comprising transnational corporations (TNCs) (n = 127) and numerous others representing their interests. NGOs, affected communities and low- and middle-income country actors remain underrepresented. The central involvement of TNCs which rely on the production and sale of unhealthy and unsustainable commodities represents a clear conflict of interest to the stated objectives of the MSIs. These findings lend weight to concerns that MSIs may reflect rather than challenge existing power structures, thus serving to maintain the status quo. This indicates a need to critically examine the use of multistakeholder governance approaches and their ability to drive global food system transformation.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 5","pages":"1223 - 1234"},"PeriodicalIF":5.6,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01476-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, analysis of the effects of forest sector participation on food security in such contexts remain limited. Here we estimate the effects of participation in forest-based activities like collection and processing of timber and non-timber forest products (NTFPs) on household food security in Liberia, the most forested country in West Africa. We applied endogenous switching poisson regression to data from 1408 households living in the proximity of forests included in Liberia’s 2019 national household forest survey to estimate the effect of forest sector participation on food security (in terms of reduction in the number of months households reportedly had insufficient food). Results show that forest-sector participation reduced the number of months households had insufficient food by 84% (about 2.7 months). Heterogeneity analyses show that NTFPs affected food security by 80% (about 2.5 months) compared to timber and wood products, which had a 66% effect size (about 2.1 months) on average. Our results provide new, national-scale evidence on the role of forests in enhancing food security in Liberia and suggest the importance of forest sector participation for food security and achieving SDG 2 more generally.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 5","pages":"1099 - 1124"},"PeriodicalIF":5.6,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01468-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study utilized weekly panel survey data collected over a period of 94 weeks (March 2021–December 2022) from drought-prone pastoral regions and estimated two-stage least squares instrumental variables regression to assess causal impacts. We found that an increase in the normalized difference vegetation index (NDVI) – our proxy for forage condition – by 10% significantly reduced the likelihood of a household experiencing food insecurity by 12 percentage points. The main mechanisms through which improved forage condition increased food security were livestock productivity enhancement, reduced prices of basic food commodities (cereals, legumes, and vegetables), and utilization of better coping strategies by households. These findings suggest the need for interventions and initiatives aimed at boosting livestock productivity and reducing vulnerability to drought-induced poor forage conditions. Efforts focused on the monitoring of forage conditions and supporting market development for livestock feed are important for addressing the adverse impacts of drought and deteriorating forage conditions in the horn of Africa. Furthermore, the monitoring of drought conditions and shocks using high-frequency data has the potential for providing early warning and informing anticipatory action. </p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 5","pages":"1265 - 1289"},"PeriodicalIF":5.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01473-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141746334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we develop a food security social-ecological risk assessment framework for developing communities in coastal areas of the Western Indian Ocean facing a changing environment. The framework integrates local ecological knowledge, expert scientific opinion, survey data, and satellite sea surface temperature (SST) and chlorophyll-a observation. We conducted a local-scale case study in four regions in Tanzania; Mafia, Pemba, Tanga, and Unguja, revealing that they face moderate to high risk levels of food insecurity. The highest risk was observed in the island communities of Pemba and Unguja, while the communities of Mafia and Tanga had the lowest risk due to lower exposure and sensitivity to climate change. Our results show that recognizing the key differences across risk components is crucial in identifying effective intervention strategies for local practitioners.

Low income households with children age &lt; 2 years in Lima and Huánuco participated in three repeated cross-sectional surveys from 2020 to 2022 (n = 759). We assessed changes in household food insecurity experience using the Food Insecurity Experience Scale. Correlates of moderate-severe food insecurity were analysed using univariate and multivariable linear mixed-effect regressions. We also assessed perceived impacts of the pandemic on livelihoods, coping strategies and receipt of financial or food assistance. Moderate-severe food insecurity was 47.0% in 2020 (survey 1) decreasing to 31.1% in 2022 (survey 3). In adjusted analyses, food insecurity was higher in households with perceived reduced income (β = 12.69 [6.82; 18.56]); in the lower socio-economic status (SES) tertiles (<i>compared to the relatively highest SES tertile</i>; middle tertile (β = 20.91 [9.89; 31.93]), lowest tertile (β = 39.37 [28.35; 50.40]); in households with ≥ 2 children &lt; 5 years (β = 8.78 [2.05; 15.50]); and in Lima (<i>compared to Huánuco</i>; β = 10.47 [1.27; 19.67]).
