The updated framework shows the interconnected nature of the three main pathways—own-consumption, income, and women’s empowerment—along with other pathways and includes contextual factors, which were lacking in previous frameworks. Eight Livestock CRP projects were reviewed, including five integrated livestock and human nutrition projects, two studies on drivers of food choice, and one study to develop and test a tool to measure nutrition outcomes among pastoralists. Key lessons learned were that women’s empowerment in livestock-to-nutrition pathways is important, but challenging to measure; engaging male partners improves nutrition in livestock-keeping households; nutrition-sensitive livestock programs and researchers should articulate and measure livestock-to-nutrition pathways they are addressing; livestock keeping does not guarantee access to animal source foods; context and livelihoods are not static and program design should be adapted accordingly; and digital data collection systems can provide accurate and timely nutrition information. Key recommendations include developing tools to fill measurement gaps; creating shorter versions of validated tools for ease of use; using complexity-aware evaluation methods to capture the interconnected nature of livestock-to-nutrition pathways and shifting livelihoods; and conducting pathways analyses to better understand linkages in the framework and further refine it.\u0000</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"15 5","pages":"1293 - 1312"},"PeriodicalIF":6.7,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-023-01382-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41080308","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}

We also analyse the factors that may explain why those actors demonstrate different capacities to resist and to adapt to shocks. For this purpose, we use a series of econometric models in which the change in actors’ economic activity is linked to a series of variables, including their exposure to insecurity, sociodemographic characteristics, wealth and social network. Overall, our analysis shows that local food system actors have reduced the volume of their economic activity by about 50% between mid-2020 and mid-2021. The analysis also reveals that actors who were exposed to more frequent violent events are more likely to have opted for strategies that are detrimental for their businesses; and that food system actors who have broader social networks are able to mitigate better the impact of armed conflict. In contrast, no robust evidence was found about the potential mitigating effect of actor’s individual wealth.

Our results suggest that various social protection programmes can operate synergistically and deliver positive impacts on children and women’s nutrition or health, even though this is not their main objective. However, the effects are heterogeneous and confirm that the nutrition and health benefits, reached through a combination of the two social protection programmes, are mediated by intrahousehold dynamics.

There is a perception that higher incomes, growing population, urbanisation, and increased productivity in the industry have influenced Indian poultry consumption. However, consumer surveys have shown that the average poultry consumption in India has remained low. With this in mind, the paper analysed household determinants of chicken and egg consumption within the Indian population, using two rounds of National Sample Survey data (1993–1994 and 2011–2012). By conducting a spatiotemporal analysis of household consumption and expenditure survey and by using truncated Double Hurdle and Unconditional Quantile regressions (UQR) models, this study explored socio-economic and food system determinants of chicken and egg consumption in India. Key results highlight that while consumption has increased marginally over twenty years, supply-side determinants, such as price and poultry production concentration, influenced heterogenous consumption patterns in India. We also find evidence that historically marginalised groups consumed more chicken and eggs in comparison to non-marginalised groups and preliminary evidence suggests how household gender dynamics influence different consumption patterns. Adequate consumption of poultry is important to improve nutrient-deficient diets of vulnerable groups in India. Our findings on demand side determinants of poultry products are crucial to support consumer tailored actions to improve nutritional outcomes along with the Indian poultry sector policy planning.\u0000</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"15 5","pages":"1231 - 1254"},"PeriodicalIF":6.7,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-023-01375-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41079869","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 results revealed that the total cropland area has consistently increased by 17.74% in the last four decades. The Sanjiang Plain (SJP) and Songnen Plain (SNP), with high aggregation and a simple shape of cropland landscapes, were the main regions where the cropland area has increased.

Before 2000, the total cropland area expanded more (46,748 km<sup>2</sup>) in response to the pressure to ensure food security, whereas there was less cropland loss. The accuracy of the RF model during this period revealed that the changes in cropland spatiotemporal patterns were highly influenced by climatic factors. After 2000, the climate conditions gradually became warmer and wetter. The total area of cropland increased slightly (10,587 km<sup>2</sup>) under the influence of the contradictory relationships among economic development, food production and ecological conservation, and the conversion between cropland and natural landscape types was drastic. The impact of climatic factors on changes in cropland spatiotemporal patterns has declined.

The aim of this study was to analyse two multilateral trade policy decisions relevant to food and nutrition security, to understand the political and power dynamics in the spaces in which these decisions are being made at the global level, in order to strengthen trade-related food systems governance to improve population nutrition. This qualitative policy analysis drew on data from a targeted literature and policy review, as well as in-depth interviews with eight individuals with expert knowledge and/or involvement in the case studies. The analysis focussed on policy processes and power dynamics, drawing on two frameworks from political science. This study found that power dynamics were shifting, such that developing countries had more of a voice at these multilateral negotiations, and decisions reflected growing resistance from developing countries who were unable to protect their most vulnerable. Contextual factors such as level of food insecurity, socio-economic situation, and historical institutional processes at the World Trade Organisation, were influential in shaping actor agendas.

While addressing issues arising from the pandemic is dramatically urgent, this should not come at the cost of averting resources and efforts from sustainable and equal growth and prosperity goals. The importance of resilience for the humanitarian and development nexus, has probed United Nations agencies, international organizations, donors, and governments to investigate key facts and determinants of this capacity. After approximately 15 years of empirical evidence, few research questions remain unexplored and unanswered. Are there few and consistently relevant elements that determine resilience capacity? What shocks are most dramatically reducing resilience? What coping strategies are most frequently adopted in the presence of shocks? This paper attempts to respond to these questions by pooling together a unique database of 35 countries. This study combines the most recent FAO-RIMA (Resilience Index Measurement and Analysis) datasets with a large set of data from the Multiple Indicator Cluster Survey (MICS) produced by the United Nations International Children's Emergency Fund (UNICEF). The analysis covers the period between 2014 and 2020 by investigating 50,622 households. The size of the sample provides our findings with great statistical power, therefore adding external validity. Our results show that firstly, diversification of income sources, education, access to land, livestock, and agricultural inputs, are the main drivers of households’ resilience capacity. Secondly, we gather evidence that the prevailing shocks are natural, health, and livelihood. Thirdly, we find that reducing the quantity and quality of food consumed, seeking an extra job, selling assets, taking credit, relying on relatives and social networks are the most adopted coping strategies. Finally, we found evidence of how mitigating strategies are adapted to the shocks: for instance, increasing working hours is adopted when a natural shock occurs while accessing credit is chosen when health shocks occur. Our results show that adequate investments in resilience are conditional to a) engaging with activities that are broadly consistent across countries and b) fine-tuning the interventions based on context specificity.\u0000</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"15 5","pages":"1161 - 1183"},"PeriodicalIF":6.7,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41079795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
