FOOD SECURITY IN SUDAN: A HISTORICAL ANALYSIS OF FOOD AVAILABILITY

Achieving global food security is one of the major challenges of the coming decades. In order to tackle future food security challenges we must understand the past. This study presents a historical analysis of global food availability, one of the key elements of food security. By calculating national level dietary energy supply and production for nine time steps during 1965–2005 we classify countries based on their food availability, food self-sufficiency and food trade. We also look at how diets have changed during this period with regard to supply of animal based calories. Our results show that food availability has increased substantially both in absolute and relative terms. The percentage of population living in countries with sufficient food supply (>2500 kcal/cap/d) has almost doubled from 33% in 1965 to 61% in 2005. The population living with critically low food supply (<2000 kcal/cap/d) has dropped from 52% to 3%. Largest improvements are seen in the MENA region, Latin America, China and Southeast Asia. Besides, the composition of diets has changed considerably within the study period: the world population living with high supply of animal source food (>15% of dietary energy supply) increased from 33% to over 50%. While food supply has increased globally, food self-sufficiency (domestic production>2500 kcal/cap/d) has not changed remarkably. In the beginning of the study period insufficient domestic production meant insufficient food supply, but in recent years the deficit has been increasingly compensated by rising food imports. This highlights the growing importance of food trade, either for food supply in importing countries or as a source of income for exporters. Our results provide a basis for understanding past global food system dynamics which, in turn, can benefit research on future food security.

Few studies examine the distribution of food insecurity in advanced capitalist nations. This research investigates cross-national food insecurity in the world’s largest economies by estimating the impact of welfare spending and income inequality on food availability (measured by the FAO’s Dietary Energy and Protein Supply indicators) and food accessibility (measured by the Food Insecurity Experience Scale) in 36 Organization for Economic Cooperation and Development (OECD) countries between the years of 2000 and 2018. Using a series of regression models on panel and cross-sectional data this research found that increases in state spending on social and health care are associated with (1) increases in food availability and (2) increases in food access. However, the findings also suggest that increases in food supplies do not produce more food security. Thus, for the OECD countries in this analysis, food availability is unrelated to food accessibility. We conclude by suggesting that high income countries that seek to promote global health should not only focus their efforts on poverty reduction polices that increase food accessibility within their own boarders, but must simultaneously ensure a more equitable global distribution of food.

Although organic agriculture (OA) is praised unequivocally for its environmental and health benefits, its potential for food security is often questioned because of its perceived lower yield. Least developed countries (LDCs), which have a high prospect of conversion to OA, are underrepresented in the literature related to the yield potential of OA, and its impact on regional food security. This paper aims to assess food and nutrient (calorie, protein, and fat) supply, thereby contributing to food security, from OA using yield ratio (YR) in LDCs and to compare this with North America (NA). Literature is the main source of data to estimate YR. Food supply data available in FAOSTAT for 1963–2013 along with the YR is used to estimate food and nutrient supply from OA in 2013. YR of crops shows a higher yield from OA in LDCs compared to NA. The food supply in LDCs between 1963 and 2013 increased at a higher rate than in NA. However, per capita nutrient supply is growing at a meager rate in LDCs; calorie and protein supply are just above the minimum threshold level and fat supply is still below the threshold level. Cereal is the single most important food item contributing to nutrient supply in LDCs, indicating a lack of dietary diversity. Thus, with relatively higher yields and crop diversity, and localized production and distribution systems, OA will have important contributions in dealing with persistent food insecurity in LDCs. However, a concerted effort is necessary to achieve yield gain and wider acceptance of OA.

Transitions to sustainable food systems require shifts in food production and availability, particularly the replacement of animal-based protein with plant-based protein. To explore how this transition may relate to demographic patterns, we undertake an ecological analysis of global associations between age-specific mortality, total national macronutrient distributions, and protein substitution. Our dataset includes per capita daily food supply and demographic data for 101 countries from 1961–2018. After adjusting for time, population size, and economic factors, we find associations between low total protein supplies and higher mortality rates across all age groups. Early-life survivorship improves with higher animal-based protein and fat supplies, while later-life survival improves with increased plant-based protein and lower fat supplies. Here, we show that the optimal balance of protein and fat in national food supplies, which correlates with minimal mortality, varies with age, suggesting that reductions in dietary protein, especially from animal sources, may need to be managed with age-specific redistributions to balance health and environmental benefits.

Nutrition security describes the adequacy of the food supply to meet not only energy but also macronutrient and micronutrient requirements for the population. The aim of this study was to develop a method to assess trends in national nutrition security and the contribution of imports to nutrition security, using the UK as a case study. Food supply data from FAO food balance sheets and national food composition tables were used to estimate the nutrient content of domestically produced food, imported food and exported food. Nutrition security was defined as the total nutrient supply (domestic production, minus exports, plus imports) to meet population-level nutrient requirements. The results showed that the UK was nutrition secure over the period 1961–2011 for energy, macronutrients and key micronutrients, with the exception of total carbohydrates and fibre, which may be due to the loss of fibre incurred by processing cereals into refined products. The supply of protein exceeded population requirements and could be met with domestic production alone. Even excluding all meat there was sufficient protein for population requirements. The supply of total fat, saturated fat and sugar considerably exceeded the current dietary recommendation. As regards nutrition security in 2010, the UK was reliant on imported foods to meet energy, fibre, total carbohydrate, iron, zinc and vitamin A requirements. This analysis demonstrates the importance of including nutrients other than energy to determine the adequacy of the food supply. The methodology also provides an alternative perspective on food security and self-sufficiency by assessing the dependency on imports to meet population level nutritional requirements.

Food security in a just energy transition is a growing debate about designing sustainable food secure networks worldwide. Energy transition, land-use change, and food security are crucial factors for food security and provision. The increased demand for food products and customer preferences regarding food safety provide various issues for the current agriculture food supply chain (AFSC). Along with rising sustainability concerns, strict government regulation, food security, and traceability concerns compel managers, business houses, and practitioners working in AFSC to adopt new tools, techniques, and methodologies to model current food supply chain problems. Thus, in turn, design the food logistics network for food security. Hence, this study investigates the core determinants of food security and supply in Egypt, Morocco, Tunisia, and Lebanon over the period of 2010–2019. In order to estimate the objectives of the study, we employ the fully modified ordinary least square (FMOLS) and dynamic ordinary least squares estimators (DOLS) to draw the study findings. However, the estimated results show a negative association of land use with food security and supply. Likewise, energy transition, gross domestic product, and agricultural value added (AVA) contribute to the food security supply. In contrast, urbanization's negative but insignificant contribution to the food supply in selected economies exists. Besides, another core objective of the study is to investigate the moderate role of the energy transition on the gross domestic product, agriculture sector, and land use and find the significant contribution to the food supply. However, the current study also tries forecasting for the next 10 years and employs the impulse response function (IRF) and variance decomposition analysis (VDA). Congruently, this study uses the pairwise panel causality test and finds exciting outcomes. The COVID-19 crisis has posed challenges such as energy consumption and food security issues. On behalf of the results, the current study proposes imperative policies to investigate the desired level of food supply. The findings provide valuable insights for experts, policymakers, and officials to take practical measures for energy use and food security challenges.

Before the COVID-19 pandemic it was widely reported that, in the United States, over 40 percent of food produced was wasted During the pandemic, news reports have described unprecedented household food waste, up by 30 percent according to Republic Services, one of the largest waste management services in the US (Helmer 2020) But upstream, food waste was, and continues to be, equally problematic When institutions such as schools and universities, large businesses, restaurants, and other venues must shut down, so too must the food supply chain for those locations Farmers who produce food for large-scale public use have been unable to redirect their products for grocery markets, and so in many cases their harvests and dairy cannot be used Elsewhere along the chain, farm and other food laborers (e g , meat-packing workers, delivery workers) without access to protection and health care cannot continue to pack and deliver food at "normal" levels, and so potential food has been left in fields and warehouses (Evich 2020)

At the current time, Hawai‘i lacks an established set of benchmark estimates on the availability of food for market consumption and its supply sources. This paper serves to fill a persistent gap in the existing literature by providing an estimation framework to map the existing food supply flows from various sources and to determine the various levels of food consumption in Hawai‘i. The authors suggest modified measures of food self-sufficiency and import dependency to provide a more accurate assessment on the extent of food localization in Hawai‘i. The analytical framework presented in this paper can be applied to other small, open (island or regional) economies with a food localization agenda, as it provides a more discrete and appropriate set of measurements, as well as offering the lessons gained through Hawai‘i’s experience and challenges in the data-collating process. Local production and imports (continental United States and foreign countries) of consumable food in Hawai‘i are estimated at just over 1.14 million tonnes in 2010. Food exports totaled 175.5 thousand tonnes, leaving total available food for consumption locally at 966.6 thousand tonnes. On a de facto basis, per capita food consumption in Hawai‘i is estimated at 657.9 kilograms in 2010. At the food group level, fresh vegetables lead with per capita food consumption of 84.2 kilograms, followed by other proteins at 69.1 kilograms, fresh fruits at 67.7 kilograms, fresh milk at 62.9 kilograms, and rice at 27.9 kilograms. The analysis indicates that Hawai‘i has an overall food self-sufficiency ratio (SSR) of 15.7% and an overall food import dependency ratio (IDR) of 102.5%. While it appears counterintuitive that the IDR exceeds 100%, this figure actually indicates the existence of food imports into Hawai‘i that are then turned around and re-exported to other markets. With application of the more accurate localization ratio (LR), we estimate that only 11.6% of available food for consumption in Hawai‘i was actually sourced from local production in 2010. Likewise, the modified import dependency ratio (MIDR) indicates that an estimated 88.4% of available food in Hawai‘i was sourced from imports.

BackgroundSince 2015, food insecurity has been a more serious threat than the previous years with a record high observed from the year 2020 onwards, especially in developing countries. This record could be due to response measures, notably the closure of borders due to the COVID-19 pandemic. This implies that trade openness have played an important role in achieving food security in the world. However, the debate on the effect of trade openness on food security remains no consensus in the economic literature. It is in this context that this paper aims to re-examine the effect of trade openness on food security in sub-Saharan African countries.MethodsPanel data covering 37 Sub-Saharan African countries over the period from 2004 to 2018 were mobilized. We use a dynamic empirical model based on the system Generalized Method of Moment (GMM) to control the unobserved heterogeneity and potential endogeneity of the explanatory variables. As food security is a multidimensional concept, we used four indicators (“average dietary energy supply adequacy”, “average protein supply”, “per capita food supply variability”, and “share of dietary energy supply”) to capture food security. To improve the robustness of the empirical effect of openness on food security, we also used globalization as an alternative factor to trade openness.ResultsThe empirical results show that trade openness significantly improves food security in 37 Sub-Saharan African countries. However, in the presence of political instability, a deterioration of the food security situation is observed. The results reveal also that the quality of institutions, economic growth, remittances, human capital, and the importance of the agricultural sector are also factors favouring the level of food security in sub-Saharan Africa countries.ConclusionAny policy aimed at trade openness must consider the quality of institutions to achieve the expected results.

Sustainable urbanisation assumes the maintenance of nearby wetlands and farms from an environmental standpoint. With rare exceptions, Third World cities are systematically urbanising, polluting and destroying their vital environmental support systems. For instance, uncollected trash frequently covers open areas in cities, creating mini‐utopias for rodents and mosquito‐borne disease carriers. The persistent gaps in the rates of waste production and disposal are frequently startling. Urban migration, unemployment, food prices, and growing rental housing costs have emerged as major urban problems in many Ethiopian cities. The study's primary objective was to analyse the status of food security indicators experienced by urban households and their coping mechanisms for policy implications using empirical data. The study used a mixed method research strategy that combines quantitative and qualitative research methods. Focus groups, key informant interviews, and questionnaire surveys were used to collect the data. Descriptive and inferential statistics were employed to assess the data gathered. In development studies, establishing exact, accurate, trustworthy and meaningful indicators of urban food security continue to be difficult. Despite the developing world's significant incidence of food insecurity being acknowledged, the precise number of people who lack access to food and the extent to which they are impacted remain unknown. Food security measures, such as the dietary energy supply (DES), household dietary diversity score (HDDS), and reduced coping strategy index (rCSI), were used to identify households that were food insecure. The survey found that 54% of households consumed less than 2100 kcal per adult daily and experienced food insecurity. A baseline of 2100 kcal per adult equivalent per day revealed that 56.7% of families in Bahir Dar and 52.7% of households in Gondar experienced food insecurity. Less than four food groups were consumed by 64% of households, which is far below the FAO's recommendation. The findings also showed that eating fewer meals per day, choosing fewer quality foods, and limiting portion sizes at times were the most often used coping mechanisms during food shocks. The overall findings of the study highlight an urgent need for actions that might increase the food security of the urban poor, such as price stability, the building of communal housing, enabling micro‐finance and providing starting money.
