Member States have tackled the subject with different regulatory approach, represented in Italy, by municipal regulations. The present study was designed to provide an overview of the municipal regulations pertaining to AOW, LSW, and LCW issued in Italy to date. A search was conducted on Google from December 2023 to March 2024 using specific keywords. The analysis of the regulations entailed the scrutiny of provisions concerning AOW and LSW during transport, maintenance, display and, additionally, LCW during stunning and slaughter. A total of 771 municipal regulations on animal welfare issued from 2001 to 2023 were collected. A total of 542 provisions concerning AOW were identified, while 234 and 181 provisions also addressed LSW and LCW, respectively. As regards LCW, specific regulations included the prohibition of the claws banding (85.1%), slaughter prior to sale (59.1%), and boiling of live crustaceans (33.1%). Conversely, the obligation to slaughter before sale (12.1%), after stunning (10.5%) and out of sight of the consumer (5%) were reported. The divergent and generally not scientifically-based nature of the regulations suggests limitations of the Italian approach in AOW, LSW and LCW management. In anticipation of the risk assessment-based revision of EU legislation on AOW, the results provide an updated basis for the drafting of national technical guidelines, including species-specific control checklists, for the monitoring of LCW along the entire supply chain.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102814"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143138890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper highlights the emergence of China, India and Brazil, and their increasing influence on ARIS in the South. We conceptualise global agricultural R&I cooperation (ARIC) to examine how the changing nature of the cooperation between major players from the North and the South influences ARIS transformation in the South. We propose a local–global nexus (LGN) framework to reveal multiple processes involving researchers and non-academic actors for joint knowledge production and social impact across scales. We explore LGN’s feasibility through a case study of UK-China cooperation to illustrate the necessity and key factors influencing the participation of non-academic actors including smallholder farmers in ARIC. Evidence for this paper comes from a combination of primary data collected from 52 British scientists, representatives of funding agencies and entrepreneurs regarding their experiences, opinions and perceptions of ARIC through bilateral cooperation, and second sources. This paper contributes to ARIS transformation debates from three perspectives. First, it sheds new light on transformative innovation debates by adding an ARIC element for ARIS transformation in the South. Second, it enriches a “pathways approach” by delineating four pathways of ARIC, as well as top-down and bottom-up processes across various scales.

Food price shocks, indeed, generate both winners and losers and their overall impact on income distribution cannot be predicted a priori but depends on the relative magnitude of different effects. From the empirical perspective, however, the link between international food prices and income distribution is largely understudied. The present paper tries to fill the gap by analyzing a large sample of 126 developing and developed countries observed in the period 1990–2020 and studying how food price shocks are associated with changes in income distribution. The heterogeneity of the effect is investigated by means of interaction terms accounting for the food trade balance of countries and the structure of the agricultural sector, coming to three main conclusions. First, upsurging food prices increase inequality by affecting the relative income of the poorest 50 percent of the population to the advantage of richer people, especially of the richest among the rich. Second, this effect is relevant for developing countries while no clear findings emerge for high-income countries. Third, the disequalizing effect of soaring international food prices is not uniform in developing countries but largely depends on their food trade balance and some structural attributes of their agricultural sector. In this regard, food policy must reduce the domestic transmission of price shocks to poor consumers while strengthening farmers’ productive capacity and ability to cope with the shocks through better access to land, capital and productive resources.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102830"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nutritional information is derived from food composition tables. Food items are grouped by processing level as a proxy to explore differences in own- and cross-price effects between ‘healthier’ and ‘less healthy’ items. The demand for ultra-processed sweet and savoury foods is price-inelastic (−0.74 and −0.81, respectively). Lower-income households’ demand is more price-sensitive. The reform applies a reduced rate to a significant number of ultra-processed savoury food items and is associated with an increase in household purchases of calories (0.7%), sugar (0.4%), and saturated fat (1.2%). A counterfactual scenario with a basic tax basket defined based on the Pan American Health Organization nutrient profile model criteria is associated with the largest reductions in calories (−0.2%), sodium (−1.0%), and saturated fat (−0.6%), with higher benefits for lower-income households. It results in minor decreases in household spending (−0.2%). While an increasing number of countries contemplate the taxation of foods high in fat, salt, or sugar, Costa Rica is unique in mandating the consideration of nutritional aspects in determining value-added tax rates.

Measuring nutritional insecurity is difficult to achieve at scale and so the ability to study the relationship between nutritional outcomes and deprivation at a national level is very challenging. This makes it difficult to understand the effect of new policies or track changes over time. To address this challenge, we develop a machine learning approach using massive anonymised transactional data (4 million members and 2.5 billion transactions) in partnership with the retailer The Co-operative Group UK. We engineer a series of variables related to obesogenic diets, including a new measure called ‘Calorie-oriented purchasing’. These variables help illustrate how large-scale transactional data can discriminate between neighbourhoods most affected by deprivation and childhood obesity. Through comparative assessment of machine learning approaches, we find better performance from tree-based models (Random Forest, XGBoost) with the best-achieving accuracy of 0.88 for predicting deprivation and an accuracy of 0.79 for childhood obesity. Calorie-oriented purchasing emerges as a robust predictor of deprivation and childhood obesity at the census area level. Results show this approach can help summarise nutritional insecurity, and support its spatio-temporal monitoring.

This study aims to refine yield response and profitability models by incorporating recent data from nationally representative and panel datasets spanning six countries. Most countries exhibited low nitrogen yield responsiveness (4–7 kg), while Ghana and Uganda showed higher responsiveness (15–20 kg) per additional 1 kg of nitrogen. Analysis of fertilizer-to-maize price ratios from 2010 to 2023 showed a downward trend, with spikes in 2022 in Ghana, Malawi, Nigeria, and Tanzania. Overall, except for those years, the data suggest a trend of increasingly favorable price incentives for fertilizer use. Ethiopia, Tanzania, and Uganda experienced declines in the fertilizer-to-maize price ratio. Increasing inorganic fertilizer use would be profitable in Ethiopia, Ghana, Nigeria, and Uganda at current market prices, but not in Malawi or Tanzania. Subsidies in Malawi and Tanzania have boosted profitability, but these may not be necessary in Ghana, Nigeria, or Uganda, which already have favorable price incentives; Malawi could benefit by substantially reducing its 80 percent subsidy while maintaining decent price incentives and farm profits.
