“…T = αu 1 + βu 2 (7) where U represents the coupling degree, T is the comprehensive evaluation index between CLES and CM, D is the CCCD (0 ≤ D ≤ 1), and α and β denote the weight coefficients of the two, respectively. Taking into account the equal importance of the two under the coordinated development, α = β = 0.5, u 1 represents CLES (0 ≤ u 1 ≤ 1), and u 2 represents CM (0 ≤ u 2 ≤ 1).…”

“…With the advancement of high-quality socio-economic development, the need for cropland is no longer restricted to a single function of food supply [1,2], but it is rapidly expanding to include derived purposes such as livelihood security, landscape aesthetics, 2 of 26 recreation, and tourism [3,4]. At the same time, due to the pressures of global change and the intensification of human activities, cropland resources across the world continue to face non-agriculturalization, non-food marginalization, and reverse ecology [5][6][7]; in turn, this is constantly changing the cropland landscape patterns [8,9], such as the trend of cropland fragmentation due to the interference of various non-farm activities, which has a significant impact on the continuous supply of multifunctional cropland and limits the sustainable use of cropland resources [10,11]. Therefore, it is important to enhance the understanding of the relationship between landscape patterns and multifunctional evolution in cropland systems to further serve the management of cropland resources.…”

Cropland is an essential strategic resource, for which landscape ecological security and multifunctionality evolution are related to regional stability and sustainable social development. However, few studies have explored the spatial heterogeneity of the coupling between the two from a multiregional and systematic perspective, and the interaction mechanisms have still not been thoroughly analyzed. In this study, a typical karst trough and valley area in the mountainous regions of southwest China was selected as the research object, and by establishing a multi-indicator evaluation system using a landscape pattern index, a multifunctional identification model, a coupled coordination model, and a geodetector model, the spatial variability in the evolutionary characteristics and the coupling and coordination of cropland landscape ecological security (CLES) and cropland multifunctionality (CM) in the mountainous regions of the southwest and their driving mechanisms were explored. The main results were as follows: (1) CLES in the mountainous areas of southwest China has undergone an evolutionary process of first declining and then slowly rising, with the characteristics of “fast declining in the high-value areas and slow rising in the low-value areas”, while CM showed a spatial distribution of “high in the northwest and low in the northeast”, with positive contributions originating from ecological functions. (2) Over the 20 years, the cropland coupling coordination degree (CCCD) values showed significant spatial heterogeneity, which was regionally expressed as ejective folds (EF) > TF (tight folds) > TLF (trough-like folds) > AF (anticlinorium folds). Low CCCD values were primarily found in the east, whereas high levels were primarily found in the west, with a rapidly diminishing trend. (3) There were differences in the driving mechanisms of CCDD in different landscapes, but GDP was still the determining factor and had a limiting effect. Hence, we call for the adoption of a “function over pattern” approach in areas with more development constraints and a “pattern over function” approach in areas with fewer development constraints. Ultimately, this study will contribute to the formation of a coupled cropland mechanism system described as the “multi-mechanisms drive, multi-elements integrated” system. In conclusion, this study can provide a better understanding of the relationship between cropland patterns and multifunctionality, which can help provide a basis for cropland conservation and landscape planning in similar mountainous areas and promote the achievement of sustainable agricultural development goals in the mountainous areas of southwest China.

“…As food is the main resource that drives economic and social stability in developed countries and food security promotes positive effects on human capital and reduces volatility and violence in a country (Agrinatural, 2017; World Economic Forum, 2016), economic growth in developing countries and reduce governments’ expenditure on health has to be promoted (International Food Policy Research Institute (IFPRI), 2014). This is more obvious in developing countries like Ethiopia, where postharvest losses account for 10% of countries’ annual budget (Teferra, 2022). Contrastingly, food insecurity is identified as the main driver of immigration with people fleeing the poverty and hunger of their country and searching for a better future (Da Silva Miranda Sechi and Marques, 2017).…”

Food waste (FW) has become a global concern, with an estimated 1.3 billion tonnes lost annually, costing about $1 trillion. Environmental and social consequences of FW are significant, contributing to 6% of European Unions’ greenhouse gasemissions and affecting global food security. FW occurs is a complex issue occurring at various stages of the food supply chain (FSC) and is influenced by multiple factors such as infrastructure, available knowledge and socio-economic conditions. Developed countries FW is more prevalent at the consumption stage, whereas in the developing countries losses occur in agricultural production, post-harvest and distribution stage. Accurate quantification of FW across the supply chain is crucial and monitoring key performance indicators helps identify areas for improvement. The European Union mandates FW measurement, aligning with sustainable development goals, emphasizing the need for effective waste prevention measures. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach was utilized to conduct a systematic literature review on FW key performance indicators (KPIs) and monitoring tools. The research identified 22 KPIs, categorized into three levels of the FSC: primary, secondary and tertiary. The most common KPIs included FW per capita, FW per portion and FW percentage. The study further discusses FW prevention measures and essential monitoring tools for addressing FW throughout the supply chain.

“…Depending on the prevailing intrinsic and external factors, post‐harvest losses of grain legumes are estimated to be about 9% for the United States and 40–50% for many developing countries (Ikegwu et al, 2022). The extent of postharvest loss in Ethiopia can be expressed as economic losses amounting to 10% of the country's annual budget, which could have greatly contributed to the gross domestic product (GDP) every year (Teferra, 2022). Postharvest loss of seeds affects the field planting value and future household food security.…”

Comparison of hermetic bags with polyethylene‐lined polypropylene bags for prolonged storage of faba bean (Vicia faba L.) seeds in Ethiopia

Poor storage facilities expose seeds to deterioration, resulting in low seed quality under a prolonged storage time. We compared the performance of five bag types: Two hermetic bags (Super GrainPro bag [SGB] and Purdue Improved Crop Storage bag [PICS]), with three non‐hermetic bags (woven polypropylene bag lined with polyethylene [WPP lined with PE], polypropylene bags [PP], and jute bags) for the storage of faba bean seeds for 24 months. Faba bean seed quality was assessed under ambient conditions after 0, 6, 12, 18, and 24 months of storage. Parameters investigated include seed moisture content, thousand seed weight, germination percentages, vigor index I and II, speed of germination, percentage of insect‐damaged seed, and insect counts. Results indicated that there was a significant (P ≤ 0.01) interaction of bag types and duration for all tested parameters. Hermetic bags and WPP lined with PE maintained germination percentage above 90% during 12 months of storage. The vigor index remained above 1600 mg% for hermetic bags and WPP lined with PE during 12 months of storage. However, non‐hermetic bags exhibited a rapid drop in vigor index beginning from 6 months of storage. Hermetic bags and WPP lined with PE allowed minimal insect breeding and hence decreased the seed damage caused by insects. The present results demonstrated that in addition to the PICS bags and SGB, the WPP lined with PE can be used for short‐period storage for up to 12 months without incurring a significant loss of seed quality. Hence, we recommend the introduction of WPP lined with PE as faba bean seed storage technique under conditions where hermetic bags are inaccessible to resource‐poor farmers.
