Previous policies had envisioned a gradual shift, but the sudden ban caught agriculture off guard. Declining foreign exchange reserves to import chemical fertilizers and coinciding peak fertilizer prices appeared to support the timing of the move. However, the ensuing rush for organic fertilizers failed to meet the national demand, resulting in severe losses in rice and export-oriented plantation crops. Facing decreasing yields and food insecurity, the government lifted the ban in November 2021. The events raised critical questions about the necessity and feasibility of such a drastic transition and alternative ways. To explore the general feasibility of transitioning toward organic fertilizers, this study considered the actual and potential availability of biomass to “replace” chemical fertilizers at the national scale as was envisioned by the Government. The analysis focused on the four main national crops and showed that in none of the selected scenarios, Sri Lanka’s actual and potentially available organic fertilizer could supply rice- and plantation-based agrosystems with sufficient nitrogen, not to mention other crops or nutrients. The Government will in every scenario, including one that assumes a stepwise transition, remain compelled to spend significantly on importing organic fertilizer to maintain the required crop yields, which would cost the Government more foreign currency than purchasing chemical fertilizer. Even more costly is purchasing rice to close the national production gap, as Sri Lanka eventually did at the end of its nationwide experiment, which resulted in major food security concerns.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 3","pages":"585 - 602"},"PeriodicalIF":5.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01528-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135318","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}

In addition, improving market infrastructure such as more toilets and hand washing stations and reducing the associated costs of using these services could facilitate better adoption and adherence to good hygiene practices which has a direct impact on food safety.

The industrialisation of farming is best understood as an ongoing process rather than an achieved structure, and the industrial and subsistence forms of production are combined in complex ways during transformation. The unit of analysis shifts downwards to the production unit, namely, the ‘form of production’, which is observed at the household level. This study aims to describe the dynamics of the transformation from subsistence to industrial agriculture in Southwest China and the hybridized forms of production that lie between the two extremes. Empirical observations on the transformation of farming in Southwest China, specifically the circumstances of smallholder farmers and local farming systems in the process of industrialisation and farmers’ reasons for their resistance and persistence in traditional farming, are documented and analysed. Using data collected for 2008 and 2019, this study considers the form of production observed from production methods and dynamic farming structures to explore how farmers’ motivations and structural forces clash and interact at the farm level in the commoditization of production and to understand farmers’ autonomy within relational contexts. The study measures the resilience of farmers’ decision-making in production through their space for manoeuvring, which depends on their ability and the conditions to obtain alternative solutions at various stages of production, reflecting varying degrees of autonomy from the dominant development trajectory. The study also reveals that the rapid reduction in the cultivated area of cereals is closely related to the acceleration of agricultural industrialisation. Farmers who join the industry are systematically pressured to compete with no economic cushion when vertically organized commodity chains have shaped local production. Their forms of production are interlocked through adjacent land and crops, and the widespread domino effect has reduced farmers’ room to manoeuvre, limited farmers’ choices in production, and brought vulnerability to local farming systems. Moreover, the transformation towards sustainability has been fragmented and inconsistent.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 3","pages":"603 - 623"},"PeriodicalIF":5.6,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135517","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}

Availability alone doesn't guarantee access or adequacy, as food can be inaccessible, unacceptable, or unstable. Even when abundant, it may not meet the all requirements, and fish is equally affected by these challenges. Fish provides essential protein, micronutrients, and fatty acids to food-insecure populations. However, the contribution of fish to household or individual nutrition is influenced by its availability, accessibility, utilization, and stability. This study examines the role of fish and fisheries in food and nutritional security in the Indian context. The study was based on the framework of food and nutritional security. It undertakes a comprehensive literature analysis to gain insights into food and nutritional security as a primary concern. It also examines how fisheries can ensure sustainable availability, equitable access to nutritious fish, and stability amidst physical, economic, and social challenges. Additionally, it discusses potential risks, such as climate change, seasonality, and price volatility, which could undermine fish availability and thus, food security. The fish availability does not automatically guarantee food and nutritional security, as issues of access, nutrient adequacy, utility (quality and safety), and stability must also be addressed. Findings suggest that achieving sustainable food security through fisheries requires effective management, conservation, and policies that promote equitable distribution and long-term resource sustainability. Given the complexities and trade-offs involved in balancing human needs with environmental protection, reforms are needed in the fish supply chain. These reforms should improve market conditions, infrastructure, pricing, safety, quality, and sustainable fishing practices.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 3","pages":"749 - 765"},"PeriodicalIF":5.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135424","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}

One of the main issues associated with animal protein production (APP) is the significant amount of green-house gas (GHG) emissions. Replacing proteins from terrestrial animals that generate a high carbon footprint with proteins from aquatic animals that associated with a low carbon footprint may mitigate, or even reverse, climate change. Bivalves are known to be climate-friendly sources of animal proteins with very high nutritional quality. Despite the number of reports dealing with the carbon footprint of bivalve proteins, the information is not well organized. This reviews offers a synthesis on the impact of bivalve aquaculture on GHG emissions. Many studies have assessed the carbon sequestration potential of bivalves based solely on their respiration and the calcification process, which controversial results, because bio-calcification is highly influenced by the buffering capacity of carbonate systems in their natural habitats. Taking into account the ecosystem implications of bivalve aquaculture, the contribution of bivalve APP to carbon sinks appears to be substantial, mainly by promoting sedimentation of organic carbon for long term storage in seabed and by enhancing primary productivity through the nutrient cycles. The review also discusses other bivalve aquaculture-related components that are often overlooked (i.e., on-farm processing, post-harvest, and ultimate fate of shells). This review generates suggestions for minimizing GHG emissions. This review helps assessing the current state of research and identifying research directions for bivalve APP in slowing or even reversing climate change.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 3","pages":"739 - 748"},"PeriodicalIF":5.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01530-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135437","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}

This study examines this topic among traditional market vendors in Hawassa, Ethiopia using in-depth qualitative interviews and cognitive mapping techniques. We synthesize the data to consider vendors’ capacity to provide safer food and their incentives to do so. The results show that vendors’ food safety actions were limited, and they saw considerable barriers to enacting recommended practices, particularly due to the limited infrastructure available in the market. Capacity is limited by the fact that, while vendors have some understanding of key concepts related to food safety, there are also large gaps in their knowledge. Generally, vendors face few regulatory incentives: they have limited interactions with authority figures, including for food safety. Social incentives are also limited: food safety was not a top concern for vendors nor was it prominent in their interactions with consumers, who focused mostly on price. Results are interpreted to discuss the way forward for improving food safety in traditional markets in Ethiopia, taking into account these constraints.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 2","pages":"331 - 344"},"PeriodicalIF":5.6,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01526-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769896","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}
