Food riots: Media perspectives on the causes of food protest in Africa

When food prices spiked in 2007–8, urban Africa experienced more instances of food riots than any other part of the world. Problems were then encountered again during the 2010–11 food price spikes. This paper explores the cases of 14 African countries where food riots occurred during these two periods by presenting a qualitative content analysis of news reports on the riots drawn from both global and local African news sources. This analysis highlights the ways in which the media portrayed the links between food price rises and food riots in Africa. Briefly, our results show that the international media generally portrayed poverty and hunger as the factors that linked the incidence of food price rises with the occurrence of riots. By contrast, the African media tended to portray food riots as being caused by a more complex set of factors, including citizen dissatisfaction and people’s ability to mobilize. Exploring both the international and local interpretations of the drivers behind the food riots is important for the understanding of the multi-scalar and multifaceted factors that shape increasing food insecurity in urban Africa.     

The Cereal Market and the Role of Fermentation in Cereal-Based Food Production in Africa

Cereals represent the main crop in Africa (45% of arable land) and make an important contribution to the human diet in this continent. Cereals for humans are not consumed raw. Fermentation technology is widely used in Africa to transform cereals into edible products as well as to preserve and enhance the nutritional and safety aspects of cereals. In general, in Africa, this process is not controlled and is devoid of good manufacturing practices (GMPs). Spoilage and/or pathogenic microorganisms may compromise the final quality when the fermentation is not controlled. This article focuses on the role that the fermentation process could play in creating safe food conditions in Africa. Taking into account the increasing demand for cereals, in particular maize and rice, which contain undesired microorganisms, fermentation can play an important role in creating food security and safety. Here, the authors report a detailed analysis of the cereal market, the main transformation processes used to obtain a variety of products from cereals, the most current information on the microbial ecology of the most important traditional fermented cereals, and the safety aspects of and the technological parameters for the selection of the strains to be used as starters for African cereal-based fermented products.     

Promoting food security and enhancing Nigeria's small farmers' income through value-added processing of lesser-known and under-utilized indigenous fruits and vegetables

In Nigeria and other African countries, there are hundreds of lesser-known indigenous crops as well as other food plants gathered from the wild that contribute to food security and play vital roles in the nutrition of the people particularly the rural populace. These native crops and wild food plants that have received little research attention or extension activities and have been largely neglected by the mainstream of international science include a wide variety of wild indigenous fruits and vegetables that enrich the diet of the rural populace and could thrive with little care and without the use of costly agricultural inputs such as fertilizers, herbicides and pesticides. Among them are numerous fruits of Nigerian trees that grow wild in the rain forest and the woodland savanna zones or are cultivated on small, compound farms. These fruits that are consumed fresh are rich sources of nutrients including ascorbic acid, provitamin A carotenoids, minerals and nutraceuticals with health-promoting benefits. There is the need to promote the cultivation and utilization of many of these indigenous fruit trees including African star apple (Chrysophyllum albidum), African mango (Irvingia gabonensis), African or native pear (Dacryodes edulis) and hog plum (Spondias mombin) that are also of considerable environmental significance and protect them from uncontrolled wood felling activities that result in deforestation. Laboratory studies have shown that good quality fruit leathers, jams, juices and other drinks can be produced from several lesser-known and under-utilized Nigerian fruits and vegetables including African star apple (C. albidum), African mango (I. gabonensis), hog plum (S. mombin), tamarind (Tamarindus indica) and roselle (Hibiscus sabdariffa) using simple procedures suitable for small-scale commercial production including osmotic dehydration, open-kettle jam-making process and mechanical juice extraction followed by hot water pasteurization. Removing the constraints to the development of small-scale food industries which include inadequate electricity supply, use of inappropriate technology, inadequate working capital, high interest rates, and limited access to banks and other financial institutions would facilitate commercial production of these value-added foods in rural communities thereby reducing post-harvest losses, promoting food security, enhancing small farmers' income and contributing to sustainable rural development.     

Evaluation of the Use of Web Technology by Government of Sri Lanka to Ensure Food Security for its Citizens

Web technology is one of the key areas in information and communication technology to be used as a powerful tool in ensuring food security which is one of the main issues in Sri Lanka. Web technology involves in communicating and sharing resources in network of computers all over the world. Main focus of food security is to ensure that all people have fair access to sufficient and quality food without endangering the future supply of the same food. In this context, web sites play a vital and major role in achieving food security in Sri Lanka. In this case study, websites pertaining to Sri Lankan government and link with food security were analyzed to find out their impact in achieving the goals of food security using web technologies and how they are being involved in ensuring food security in Sri Lanka. The other objective of this study is to make the Sri Lankan government aware of present situation of those websites in addressing food security related issues and how modern web technologies could be effectively and efficiently used to address those issues. So, the relevant websites were checked against several criteria and scores were used to assess their capabilities to address the concerns of food security. It was found that the amount of emphasis given by these websites to address the issues of food security is not satisfactory. Further, it showed that if these web sites could be improved further, they would generate a powerful impact on ensuring food security in Sri Lanka.     

The era of sustainable agricultural development in Africa: Understanding the benefits and constraints

Sustainable agriculture has the potential to address some of the fundamental challenges facing agricultural practices in Africa especially in Sub-Saharan Africa (SSA). The agriculture sector plays an important role as the engine of economic growth in SSA. In this article, we ask the following key question: Can sustainable agriculture save Africa from poverty and food insecurity? To address this fundamental question, we examine and critique evidence of the benefits and challenges associated with the adoption of sustainable agricultural practices in Africa. Improving agricultural sustainability is fundamental to food security and poverty reduction, particularly in achieving elements of the sustainable development goals (SDGs) by 2030, but it will not solve all these problems alone. In consort, African governments and the international community must increase their efforts in tackling problems such as conflicts, civil war, political instability, and disease. Therefore, agricultural policy at the national, regional, and local levels and institutional reforms must be designed to benefit food security, poverty reduction, and income growth at the household level.     

Declining global per capita agricultural production and warming oceans threaten food security

Despite accelerating globalization, most people still eat food that is grown locally. Developing countries with weak purchasing power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices or production declines. Local agricultural production, therefore, is critical to both food security and economic development among the rural poor. The level of local agricultural production, in turn, will be determined by the amount and quality of arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related technology, practices and policies. This paper discusses several emerging threats to global and regional food security, including declining yield gains that are failing to keep up with population increases, and warming in the tropical Indian Ocean and its impact on rainfall. If yields continue to grow more slowly than per capita harvested area, parts of Africa, Asia and Central and Southern America will experience substantial declines in per capita cereal production. Global per capita cereal production will potentially decline by 14% between 2008 and 2030. Climate change is likely to further affect food production, particularly in regions that have very low yields due to lack of technology. Drought, caused by anthropogenic warming in the Indian and Pacific Oceans, may also reduce 21st century food availability in some countries by disrupting moisture transports and bringing down dry air over crop growing areas. The impacts of these circulation changes over Asia remain uncertain. For Africa, however, Indian Ocean warming appears to have already reduced rainfall during the main growing season along the eastern edge of tropical Africa, from southern Somalia to northern parts of the Republic of South Africa. Through a combination of quantitative modeling of food balances and an examination of climate change, this study presents an analysis of emerging threats to global food security.     

Postharvest processes of edible insects in Africa: A review of processing methods,and the implications for nutrition,safety and new products development

In many African cultures, insects are part of the diet of humans and domesticated animals. Compared to conventional food and feed sources, insects have been associated with a low ecological foot print because fewer natural resources are required for their production. To this end, the Food and Agriculture Organization of the United Nations recognized the role that edible insects can play in improving global food and nutrition security; processing technologies, as well as packaging and storage techniques that improve shelf-life were identified as being crucial. However, knowledge of these aspects in light of nutritional value, safety, and functionality is fragmentary and needs to be consolidated. This review attempts to contribute to this effort by evaluating the available evidence on postharvest processes for edible insects in Africa, with the aim of identifying areas that need research impetus. It further draws attention to potential postharvest technology options for overcoming hurdles associated with utilization of insects for food and feed. A greater research thrust is needed in processing and this can build on traditional knowledge. The focus should be to establish optimal techniques that improve presentation, quality and safety of products, and open possibilities to diversify use of edible insects for other benefits.

Preface: Challenges and opportunities for enhancing food security in Kenya

Achieving sustainable food security in Sub-Saharan Africa is one of the main challenges facing African governments and the international community. The 2007?C2008 food crisis and ongoing chronic hunger problems clearly demonstrate that millions of people on the continent, including in relatively stable countries such as Kenya, are dangerously vulnerable to economic, political and climatic shocks that threaten food availability and accessibility. At the heart of the strategies to build resilience and tackle food insecurity is the need for effective institutional and policy frameworks that can support local innovations while taking into account the biophysical, social and economic constraints within which rural livelihoods operate. The papers included in this Special Issue of Food Security support the view that for food security initiatives in Kenya to be effective, they must embrace solutions that are equitable, generalizable and ecologically sound to ensure sustainability. Ultimately, to improve innovation and technology adoption, a systems approach that allows women and men, wealthy and poor farmers to engage with scientific and political elites in the design and implementation of food-related research and development initiatives must be embraced. There is also the need to develop tools and approaches that can assist smallholder farmers, researchers, policy makers and other stakeholders to share a better understanding of the multiple factors driving food insecurity and hindering the implementation of effective policies and institutions.     

Developing community-based food security criteria in rural Tanzania

Food security remains a major challenge in Sub-Saharan Africa. The widely acknowledged definition of food security and its four dimensions, availability, access, utilisation and stability, are somewhat abstract in the local context of small-scale farmers. Therefore, more site-specific information on the local food situation is needed to respond to the local food security challenges. Participatory elaboration of these criteria within the rural communities is crucial. The objective of this research was to elaborate community-based criteria in four selected study villages of Tanzania. We present an adapted methodological procedure based on the so-called Framework for Participatory Impact Assessment (FoPIA). Based on a series of farmer workshops, we analysed the local understanding of food security and derived a set of food security criteria. We found that these criteria cover the three dimensions of sustainability (social, economic and environmental), while simultaneously representing the four food security dimensions, showing that rural communities think holistically and consider multiple criteria and dimensions related to food security. Our participatory methodological approach was suitable for identifying the specific development priorities that need to be addressed for improved food security in a particular locality. The locally specific food security criteria can be used for impact assessment, monitoring and evaluation and, finally, for the adaptation of development measures to local contexts.     

From lesser‐known to super vegetables: the growing profile of African traditional leafy vegetables in promoting food security and wellness

There are hundreds of traditional leafy vegetables and wild food plants of horticultural and nutritional significance in Africa. These lesser‐known crops and wild food plants that are highly adapted to harsh growing conditions thrive with little care and are available when other sources of food fail or are out of season. They are rich in micronutrients and are often the cheapest sources of many essential vitamins and minerals in many localities. Many of them are very important functional foods in African traditional diets and are rich in nutraceuticals, including polyphenols, tannins, flavonoids and flavonols, that exert demonstrable antioxidant, free radical scavenging and enzyme inhibition activities and have antimicrobial properties that provide scientific justification and possible mechanisms for their use in the management of a wide range of ailments, including diet‐related, non‐communicable diseases such as diabetes, hypertension and cardiovascular diseases. African traditional leafy vegetables are invaluable in promoting food security and wellness in Africa on account of their availability and affordability, their great nutritional value, chemotherapeutic and health‐promoting properties and other unique qualities. Long recognised by the rural populace as quality food items, they are becoming more popular even with the more affluent urban elites. There is the need to develop improved management practices for these super vegetables to promote their cultivation and boost their exploitation for food security and wellness in Africa. © 2018 Society of Chemical Industry     

Symposium 5: Integrated Food Systems for Food Security in a Changing World Environment

ABSTRACT: Thirty years ago, roughly 80% of Africans and Asians lived in rural environments, many sustained by subsistence farming. It was then logical for development agencies to give priority to raising harvest yields of the crops on which most poor people's food security depended. Today almost half of all Africans and Asians live in urban communities, expanding at between 3.5% and 4.5% per year. Food security for densely populated mega-cities cannot be assured simply by raising crop and livestock production. Assured access to an adequate food supply demands complex, integrated food systems: the planned, controlled integration of production with post-production systems, and these must embrace all critical components and activities from on-farm production to ultimate consumers. Diagnosis of existing patterns of production, preservation, processing, and distribution, followed by design of more efficient systems, calls for professional food systems analysts. Recent experience in India and South Africa illustrates how integrated food systems can contribute to sustained food security and stable employment in rural agribusiness.     

Challenges in Food Safety as Part of Food Security: Lessons Learnt on Food Safety in a Globalized World

Food safety should accomplish food and nutrition security. A key challenge to scale up food safety globally is to better leverage existing capacity and research working towards evidence-based decisions. At Ghent University since 2009 an annual 3-months international Intensive Training Program on Food Safety, Quality Assurance and Risk Analysis has been organized (www.itpfoodsafety.UGent.be). The trainees were asked to express their opinion on food safety concerns in their country and to select a case study to work on throughout the course. Main food safety issues had to do with bacterial pathogens, pesticide residues and mycotoxins which were challenged by lack of food safety knowledge and appropriate legislation and enforcement by government. They welcomed education and training on these topics in particular to elaborate on control measures including good hygienic practices, implementation of certified food safety management systems and setting of appropriate criteria. A number of topics are highlighted here in particular as these topics were shown to have a common ground of interest by several participants in several countries and throughout the years. These topics include among others safety of street foods, safe milk and cheese production, and risk assessment to control Salmonella and pathogenic E. coli in meat (and other foods). Although some recurring food safety issues could be identified, other topics are of particular concern in selected countries because of specific cultural appropriate eating habits. The world is changing fast. Problems change and the information stream is very intense. Leaders in food security should be aware about food safety as well, and will have to develop an attitude of continuous learning, critical thinking and be given the right tools(“know how”) to develop local solutions to address the emerging societal and environmental challenges to provide sufficient, safe, healthy, nutritious and sustainable produced food to the world's population.     

Ethical and Ethnical Requirements in the Production of Food L. E. GRIVETTI

ABSTRACT: The presentation explores ethnic food and ethics aspects of food distribution and food security. Basic principles associated with human food selection and avoidance have been known for some time (since World War I). During intervening decades, however, persistent problems have remained, including mismatched food assistance, short-sighted economic policies, lack of political will, disrespect for women's labor and decision-making skills, and, more recently, debate over zero-risk and genetically modified foods (GMFs) to reduce hunger and malnutrition. Fieldwork investigations of regional food production systems where specific food security mechanisms are identified have improved and streamlined the distribution of food supplies during and after regional or local crises. Paradoxically, such studies raise an important ethical issue, given that these same data have been and can be used by insurgents to sabotage food supplies and disrupt relief efforts. The presentation concludes with personal perspectives on associations between ethnic foods, food-related ethics, and food security. Several approaches to improving food chain security are reviewed, including micro-finance, household gardens, selected GMF technology, and how to improve existing food-related programs.     

Food and cash: understanding the role of the retail sector in rural food security in South Africa

A decline in subsistence agriculture across sub-Saharan Africa has meant an increased role for the private sector in food security strategies, but this role remains a relatively blind spot in food policy. We address this gap by analyzing retailers and consumers in a rural region of South Africa. Our results show that purchasing food is an important food security strategy for the rural poor, but is constrained by a lack of access to income. Furthermore, a reliance on specific non-perishable foodstuffs impacts the micronutrients that the poorest can access if they are unable to grow their own fresh produce. Adaptive food policy thus requires a holistic appreciation of the food system - emphasizing production as well as building livelihoods outside of agriculture.     

ScalA-FS: expert-based ex-ante assessments of local requirements and success potential of upgrading strategies for improving food security in rural Tanzania

Enhancing food security is the main goal of subsistence farmers, who are vulnerable to food insecurity in sub-Saharan Africa. Participatory research across food value chains (FVC) can help stabilize and enhance food security by developing upgrading strategies (UPS). However, prior to successful widespread adoption and geographical upscaling, such practices need in-depth understanding of their suitability in target areas and their particular local requirements. Ex-ante assessments of selected UPS were carried out by German and Tanzanian agricultural scientists using the “ScalA-FS” tool. The participating experts included those responsible for implementation. The tool aims to systematically evaluate, at the community level, UPS that have been successfully implemented elsewhere, evaluate their potential for dissemination, and identify entry points for adjustments during implementation. Assessment indicators were developed through a participatory process. UPS relate to a) natural resource management and crop production; b) food processing and bioenergy; c) income generation and market participation; and d) food consumption. Here we present the ScalA-FS assessment results on UPS suitability as well as on its implementation requirements. We focused on the local context needed to enable a productive collaboration between smallholder farmers and implementing research and/or development organizations. Implementation requirements for the selected UPS were assessed as generally low to medium, and projected suitability in most cases was high. Local knowledge and education (human capital) along with visible success after a short time were important criteria of success of UPS. Here, careful consideration of the challenges before and after implementation of UPS is suggested. ScalA-FS should be applied early in the implementation process of UPS in order to support adaptations and successful upscaling at other locations.     

African perspectives on the need for global harmonisation of food safety regulations

Africa is a large continent consisting of 54 countries at different levels of development and reflecting numerous diverse cultures. Africa's agricultural potential is largely untapped, with approximately 60% of the world's non‐cultivated arable land found in sub‐Saharan Africa. Excluding South Africa, which is the largest economy in Africa and which has a well‐established food sector with a substantial export market, economies in sub‐Saharan Africa have been steadily growing at over 5% per annum. Whilst most African countries face many challenges, including weak infrastructure as well as political and economic instability, many changes are occurring, one of these being identifying specific commodities in a particular country which warrant substantial investment for growth into export opportunities. These opportunities create an immediate need for development of food standards, including food safety standards, based on scientific principles to enable regional and international trade in food, thereby assisting in ensuring Africa's role in the global food economy. © 2013 Society of Chemical Industry     

Emerging and re-emerging diseases of agricultural importance: why local perspectives matter

This paper examines local farmers’ perspectives about emerging and re-emerging infectious diseases (EIDs) of humans, crops and livestock and their impact on household food security in the Tanzania-Uganda interface ecosystem to the west of Lake Victoria. While it is increasingly accepted that such an approach could yield vital information not only regarding the extent of the impact of EIDs but also on practical strategies for their control, recent studies have examined only a narrow part of the disease-food security spectrum, often lacking a clear analysis of how local people conceptualise the co-occurrence, interactions and impact on food security of multiple plant, animal and human disease afflictions. Findings of the present study reveal that farmers perceive diseases as products of wider social, economic, environmental and institutional realities. They employ a wide range of names to describe disease problems and often such labels have nothing in common with the binomial nomenclature used in scientific taxonomy. Frequently, local people’s perceptions of severity of the impact of disease on food security are at variance with views held by experts. Consequently, disease control measures and strategies advocated by experts and policy makers are often not adhered to. This paper reveals that local or emic perspectives on diseases not only convey the sense of how local people feel and think about a particular disease but also how such knowledge shapes their response effort. Finally, the paper argues for a strategy to harness and incorporate aspects of local perspectives and practices into formal disease control programmes.
