Abstract The rise in food prices in Turkey in the post-Covid 19 period is extremely higher than the increase in the consumer price index and the social dimension of food price. This issue prompted researchers and policy makers to examine these topics. The fact that negativities which have been observed worldwide in an emerging process are making a difference also reinforces the need for more intensive investigation of food prices or policies to be followed. This trend aims to identify the global and macroeconomic factors that cause the rise in food prices in the Turkish economy. According to this purpose, In order to measure the global impact, oil prices, the global fertilizer price index, and the world food price index were included in the study. The M2 exchange rate and money supply variables were used to measure the macroeconomic impact. In this context, monthly data for the period 2003:01–2022:03 were used in the analysis using the SVAR model. Result of the analysis indicated that global and macroeconomic factors had an impact on food prices in the period under consideration. As a result of the variance decomposition, it was observed that the food price after its own collisions was more reactive with the exchange rate, respectively.

Abstract The war in Tigray (Northern Ethiopia) that started at the beginning of November 2020 has brought devastating damage to smallholder agriculture and food security. However, empirical evidence on the effect of war on smallholder agriculture has not studied systematically. Thus, this research was initiated to address the knowledge gap. A survey was done on selected 4376 households using systematic random sampling. All the data required for the study was collected using a semi-structured questionnaire, focus group discussions and key informant interview. The study revealed that 81% of the smallholder households lost their crop followed by livestock (75%) and farm tools (48%). Overall, 94% of the households reported that at least one of their agricultural components (crop, livestock and farm tools) was looted and/or destroyed by the belligerents. Of which, 37% of the respondent’s crop, livestock and farm tools were totally damaged. Moreover, farmers have limited access to their farms, agricultural inputs, and services. Consequently, more than 5.2 million people are currently in need of immediate humanitarian assistance. To avert the worsening situation, immediate intervention is needed to deliver food and agricultural input supplies and rehabilitate the agricultural extension system and infrastructure.

Abstract Bundling the adoption of different adaptation strategies is useful in reducing multiple agricultural risks, building the resilience and supporting food security. This study analyses the effect of bundled adoption of conservation tillage, improved crop variety, and crop diversification on household food security in Ethiopia. In this study, a quantitative survey approach was used to gather household data using structured questionnaires. The data were gathered from randomly selected drought-prone districts of the Wolaita zone (southwest Ethiopia), which is often characterized by severe soil erosion, frequent rainfall variability, fragmented landholding, and poor plot tenure system, all of which threaten household food security. Household interview data were analyzed by the means of a multinomial endogenous switching model. Using the principal component analysis, the adoption of different adaptation strategies was bundled into three key components: conservation tillage, improved crop varieties, and crop diversification. The results showed that greater food security outcomes were achieved with the bundled adoption of conservation tillage, improved crop varieties, and crop-legume production compared to either of the single adoption. Adopters of the three bundles were 32.29% more food secure in terms of household food consumption score and 24.46% more food secure based on the scores of dietary diversity. The adoption of the three bundled climate change adaptation strategies was significantly influenced by the gender of the household head, farm size, and value of productive farm assets, implying that socioeconomic conditions are important factors affecting the adoption of bundled strategies and household food security. To promote bundling of adaptation strategies, frequent provision of agricultural extension services, active participation in farmer/female peers, and empowerment of women should be maintained through continuous education and gendered training.

Abstract Native sheep breeds provide milk, the raw material rich in nutrients for traditional cheese products, in selected cases labelled with the logo of the Traditional Specialty of the European Union. The study aimed to find out whether seasonal or other factors may significantly affect the composition of traditional Ewe’s lump cheese (“Ovčí hrudkový syr”) manufactured on a farm in the western region of Slovakia. For this purpose, 46 samples of fresh Ewe’s lump cheeses across the season of production undergo analysis following ISO standards focused on determining total fat, dry matter, protein, total casein, and ash. The mean values of the content of individual analytes were as follows: fat 28.60 g 100 g−1, dry matter 51.10%, protein 18.33 g 100 g−1, lactose 2.00 g 100 g−1, ash 2.16 g 100 g−1, casein 17.88 g 100 g−1. Based on statistical evaluation of the results, six significant differences have been found, namely: fat (.01), protein (.005), lactose (.005), dry matter (.05), ash (.001) and casein (.001). Considering all the evaluated aspects of such a product, the Traditional Ewe’s lump cheese presents relatively stable products in the content matter over the season.

Abstract This paper systematically sheds light on the procurement systems, the selection criteria of Supermarket agrifood suppliers, and the impact of procurement systems on producers. A systematic search of literature from 2000 to 2022 was carried out. Fifty-two peer-reviewed research articles were identified from the Scopus database. The review findings revealed a positive impact on the income, productivity, and efficiency of the suppliers of supermarkets. Supermarkets used a combination of procurement systems (modernised and traditional) but primarily used the modernised method. Most studies reported that pricing and quality of food, the safety of produce, quantity, supply stability, delivery timeliness, and trust connections determine whether supermarkets buy from small or large producers. From the study, it is suggested that, to attract and maintain consumers in the underdeveloped areas, supermarket managers have to practice a just-in-time inventory management system where stocks will be kept low and also integrate vendor relationship management to reduce the cost of fresh fruits and vegetables sold at the Supermarket.

Abstract A field survey was conducted during February–May 2022 in Chhatradev rural municipality and Sitganga municipality with the purpose of analyzing the existing value chain of arabica coffee in Arghakhanchi district of Nepal. A sample size of 110 arabica coffee growers, comprising 55 from each municipality, was selected by using three-stage sampling method for interviews that used a pretested questionnaire. To study the value addition and trading aspects, six collectors and pulper operators and two secondary processors were selected. Descriptive statistics was applied to analyze the data. Input suppliers, producers, collectors, pulper operators, secondary processors, traders, and consumers were identified as key players in the coffee value chain. NTCDB, NARC, CDC, AKC, Coffee Zone, Primary Coffee Cooperatives, Central Coffee Cooperative Union Limited, NCPA, financial institutions, and certification agencies were identified as the enabling environment providers in the value chain. The findings showed that the gross margin of one kg each of fresh cherry production, dry parchment production, green bean production, and coffee powder production was NRs. 26.06, NRs. 92.83, NRs. 107.7, and NRs. 215.06, respectively. Value addition from producers to primary processors was NRs. 109.8 per kg, and the value addition from primary to secondary processors was NRs. 445.6 per kg. Similarly, the value addition from secondary processors to consumers was NRs. 480.58 per kg. The research area’s value chain structure or network was determined to be brief and straightforward. Therefore, it is advised to adopt cutting-edge processing and packaging methods to improve the competitiveness of Nepali coffee in the market.

Abstract Maize is a major staple produced by most peasant farmers in Ghana, amidst climate variabilities that potentially thwart the attainment of global sustainable development goals (SDGs), specifically SDG −2 of zero hunger. Ordinarily, one expects the extant literature to be replete on a nexus between climate variability adaptation strategies and maize yields. Ironically, there appears to be scant information on the expected nexus in Ghana’s coastal areas. The dual questions about what adaptation strategies significantly affect maize yield, and the extent (magnitude) to which climate variability strategies affect maize yield beg answering. Inspired by these research questions, the objective of this article is to examine the effect of climate variability adaptation strategies on maize yield. This study relies on a cross-sectional data covering 197 smallholder maize farmers in the Cape Coast Metropolitan Assembly of Ghana’s Central Region. The study is deeply rooted in a quantitative approach employing multiple linear regression and a treatment effect model (inverse probability weighted regression adjustment—IPWRA). Our findings reveal that adaptation strategies correlate with maize yields. Specifically, estimates from the IPWRA show that irrigation and changes in planting dates positively correlate with maize yields. The implication is that these adaptation strategies improve maize yields. Smallholder farmers are encouraged to adopt effective climate variability adaptation strategies to minimize the adverse risks associated with climate variability. The government of Ghana’s initiative for arid regions, dubbed as the “one village one dam” initiative can be upscaled to southern Ghana to ensure sustainable agricultural development.

Abstract This study investigated the effect of gaseous ozone (O3) exposure time on the postharvest quality and shelf-life of mangoes. “Keitt” mango fruit harvested at physiological maturity was exposed to 0.25 mg/L of O3 for 12, 24,36, or 48 hours, and the control fruit were untreated. Fruit were thereafter stored at 10 ℃ for three weeks and ripened at ambient temperature for one week. Postharvest parameters such as mass loss, decay incidence, firmness, total soluble solids (TSS), titratable acidity (TA), and carotenoid content were assessed at weekly intervals. The findings showed that the physiological weight loss of untreated fruit (30.92%) was significantly higher (p <0.05) compared to O3 (12 h), O3 (24 h), O3 (36 h), and O3 (48 h) treated fruit, which was 28.49%, 25.90%, 20.54%, and 20.50%, respectively. Fruit treated with O3 (36 h) significantly maintained firmness, delayed TSS accumulation, and decreased loss of TA. The untreated fruit had a higher decay incidence compared to other treatments at the end of storage. Moreover, the total carotenoid content was notably higher in O3 (48 h) treated fruit during storage. Overall, the results demonstrated that the shelf-life of mango fruit was longer under the 36 h and 48 h treatments. These research findings indicate that O3 could be used effectively to maintain the postharvest quality and extend the shelf-life of mango fruit. Therefore, O3 (36 h) is recommended as a cost-effective postharvest treatment for “Keitt” mangoes.

Therefore, O3 (36 h) is recommended as a cost-effective postharvest treatment for “Keitt” mangoes.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43650040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract There is currently a great deal of information available about the toxic effects of oxyfluorfen on soil biochemical activity and microbial biodiversity. However, there is no information about how this herbicide affects plant growth promoting bacteria (PGPB) or their properties, such as biofilm formation, nitrogen fixation, siderophore and auxin production, and phosphate solubilisation. As such in this study an agricultural soil was polluted with the oxyfluorfen herbicide every 30 days at a dose of 4 L ha−1 for a total period of 90 days. During this experimental period, the dehydrogenase activity was determined, a count and isolation of cultivable bacteria was performed, and the PGPB and their properties were characterized. The results indicated that oxyfluorfen inhibits the dehydrogenase activity, with this inhibition increasing with herbicide concentration in the soil (69.9% compared to non-polluted soil). It also causes changes in the population diversity of cultivable bacteria in soils. Regard to the evolution of isolated PGPB, it was found that oxyfluorfen induces the growth of nitrogen-fixing, biofilm-forming, and siderophore-producing bacteria, while negatively affecting the growth of auxin-producing and phosphate-solubilising bacteria. These results suggest that oxyfluorfen modulates the properties of PGPB in a concentration-dependent manner.
目前已有大量关于氟氧芬对土壤生化活性和微生物多样性的毒性影响的信息。然而，关于这种除草剂如何影响植物生长促进菌(PGPB)或它们的特性，如生物膜的形成、固氮、铁载体和生长素的产生以及磷酸盐的溶解，还没有任何信息。因此，在本研究中，每30天用4 L ha - 1剂量的氟氧芬除草剂污染农业土壤，总共持续90天。在实验期间，测定了脱氢酶活性，进行了可培养菌的计数和分离，并对PGPB及其性质进行了表征。结果表明，氟氧芬对土壤脱氢酶活性有抑制作用，且抑制作用随除草剂浓度的增加而增加(与未污染土壤相比为69.9%)。它还引起土壤中可培养细菌种群多样性的变化。在分离的PGPB的进化过程中，发现氟氧芬诱导固氮、生物膜形成和产铁载体细菌的生长，而对生长素和溶磷细菌的生长产生负面影响。这些结果表明，氧氟芬以浓度依赖的方式调节PGPB的性质。

Abstract The lack of empirical research on the effect of financial development and interest rate on agricultural growth hinders effective policy orientation towards poverty reduction. This paper is set to examine the effect of financial development and interest on agricultural growth from the Ghanaian perspective. We used time-series data for the period 1980–2020. The time-series autoregressive distributed lag approach was used to investigate the relationship between the underlying variables. The cumulative sum chart and cumulative sum of squares statistics were used to show that our model is stable and does not contain any serious structural change. The results show that financial development and interest rates have a significantly positive effect on agricultural growth in both the long-run and short-run. The results also suggest that the government should pay more attention to both short-term and long-term policies to enhance agricultural growth through improving macroeconomic variables like reducing interest rate and enhancing accessibility to agricultural financial services in the country. We propose that agribusinesses be encouraged by enacting new financial reforms to stimulate agri-based commercial ventures, particularly in the agricultural sector. We further suggest that in order to boost agricultural growth in the country, the government should focus on lowering the prices of agri-based inputs such as seeds, fertilizers, and fuel, as well as encouraging research and development efforts. By analyzing the effect of financial development and interest rate on agricultural growth, this paper contributes to evidence-based explanations for the need to implement policies that will boost agricultural production and, hence, poverty reduction.
