But is this a realistic objective and if so, what are the pathways that lead to success? To answer these questions, we first established, as a baseline, an updated food system nitrogen budget for the EU for the year 2015. The EU used 20 Tg of virgin (new) N to deliver 2.5 Tg N in food and 1.2 Tg N in fibres to consumers, yielding a food-system nitrogen use efficiency (NUE) of 18%. We then built a simple model to combine intervention options that (a) increase farm level nitrogen use efficiencies, (b) reduce food waste increase recycling of waste and improve waste treatment, or (c) achieve a dietary shift towards healthier dietary patterns. The largest potential to increase N efficiency of the current agro-food system was found to lie in the livestock sector. From 144 possible combinations of intervention options analysed, we found that 12 combinations of interventions would reduce nitrogen losses by about 50%, 11 involving diet change. We further carried out an assessment of the societal appreciation of combinations of interventions considering private and public costs of the intervention measures, public benefit through effects on health and increased biodiversity of ecosystems, and public costs for overcoming socio-cultural barriers. Results show that a combination of moderate intervention options achieve halving of N losses at lowest societal costs. We conclude that systemic approaches are paramount to achieve deep nitrogen reduction targets and diet change appears to be an essential condition for success.</p></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"35 ","pages":"Article 100648"},"PeriodicalIF":8.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2211912422000384/pdfft?md5=7b89030cab084c79d198a4370c3c6742&pid=1-s2.0-S2211912422000384-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47871758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue is critical to measuring trade's central role as a market-based adaptation and mitigation mechanism for climate change. By conducting a meta-analysis of this literature, we elucidate several key themes that characterize this nascent body of research. First, we find that temperature in exporting places is the primary weather-based factor affecting agricultural trade and that estimates of this effect are negative in most studies. Second, the marginal effect of precipitation on trade varies greatly across primary studies in terms of sign, magnitude and location (origin or destination of trade). Third, meta-regression results uncover that the main sources of the heterogenous impact of weather on food and agricultural trade found in the primary studies originate from differences in sample size, types of commodities considered, and estimator choices. Future studies shall adopt the most recent estimation techniques, consider the role of irrigation, account for domestic trade, and provide results by commodity whenever possible.</span></p></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"35 ","pages":"Article 100654"},"PeriodicalIF":8.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45932773","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}

The framework is structured around three components: fundamental resilience concepts, resilience measurement domains, and integrated resilience measurement.

Evidence suggests that food export restrictions offer, in some cases, a temporary respite from price surges by boosting short-term domestic supply but have unintended negative consequences for food producers in most cases. The net welfare effect of food price stabilization through export restrictions depends on the net food buyers' share relative to the net food sellers' share in the economy, the relative change in producers' versus consumers' prices and the contribution of the restricted food item to household income and expenditure. In the absence of a generous producer price support program, the short-term welfare effect generated by export bans is minimal and, in some instances, negative particularly for rural residents. Food export restrictions also prevent domestic producers from taking advantage of the high international prices for agricultural commodities, stimulating the agricultural sector and boosting food production. Finally, food export restrictions lead to high economic costs in terms of lost producer revenue, forgone agricultural investments, high enforcement costs, and high fiscal costs for procuring and maintaining larger than normal food reserves.</span></p></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"35 ","pages":"Article 100657"},"PeriodicalIF":8.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44301941","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}

The results indicate that some restaurants continued to operate and offer online food delivery while lockdowns were in effect. Both the number of operating restaurants and their online food delivery services rebounded and experienced further growth after lockdowns were lifted. The adjustment path of the online food delivery business following the implementation of lockdowns differed from the adjustment path following the lifting of lockdowns. The lockdown and reopening measures did not affect all types of restaurant/cuisine equally. We also examine possible impact mechanisms of lockdown measures on online food delivery and restaurants, and conduct robustness checks to confirm the stability of the main findings.
