Exploring the impact of the 2008 global food crisis on food security among vulnerable households in rural South Africa

Recurring food crises endanger the livelihoods of millions of households in developing countries around the globe. Owing to the importance of this issue, we explored recent changes in food security between the years 2004 and 2010 in a rural district in Northeastern South Africa. Our study window spans the time of the 2008 global food crisis and allows the investigation of its...

Future threats to agricultural food production posed by environmental degradation, climate change, and animal and plant diseases – a risk analysis in three economic and climate settings

Global food security is one of the most pressing issues for humanity, and agricultural production is critical for achieving this. The existing analyses of specific threats to agricultural food production seldom bring out the contrasts associated with different levels of economic development and different climatic zones. We therefore investigated the same biophysical threats in...

The use of indigenous ecological resources for pest control in Africa

Reducing the losses from crop pests will help to increase food availability and boost economic growth in sub-Saharan Africa (SSA). However, the existing crop protection paradigm that relies on synthetic agrochemical pesticides has had only a marginal impact on the productivity of many poor smallholder farmers who constitute a major segment of agriculture in SSA. This is primarily...

An integrated agro-ecosystem and livelihood systems approach for the poor and vulnerable in dry areas

More than 400 million people in the developing world depend on dryland agriculture for their livelihoods. Dryland agriculture involves a complex combination of productive components: staple crops, vegetables, livestock, trees and fish interacting principally with rangeland, cultivated areas and watercourses. Managing risk and enhancing productivity through diversification and...

Agriculture and household nutrition security—development practice and research needs

Aligning agriculture to improve household nutrition security requires agricultural research and development specialists to understand nutrition objectives and be able to contribute to integrated agriculture-health programs. This paper builds on discussions during the household nutrition security session at the second Global Conference on Agriculture Research for Development...

Priority research questions for the UK food system

The rise of food security up international political, societal and academic agendas has led to increasing interest in novel means of improving primary food production and reducing waste. There are however, also many ‘post-farm gate’ activities that are critical to food security, including processing, packaging, distributing, retailing, cooking and consuming. These activities all...

Gender, nutrition- and climate-smart food production: Opportunities and trade-offs

Future food and nutrition security is threatened by climate change, overexploitation of natural resources and pervasive social inequalities. Promising solutions are often technology-focused and not necessarily developed considering gender and social disparities. This paper addresses issues of gender and human development opportunities and trade-offs related to promoting improved...

Crops that feed the world 10. Past successes and future challenges to the role played by wheat in global food security

Wheat is fundamental to human civilization and has played an outstanding role in feeding a hungry world and improving global food security. The crop contributes about 20 % of the total dietary calories and proteins worldwide. Food demand in the developing regions is growing by 1 % annually and varies from 170 kg in Central Asia to 27 kg in East and South Africa. The developing...

Historical trends of food self-sufficiency in Africa

The majority of African countries are stricken by food shortages and undernourishment, with much of the population lacking reliable access to food supplies and basic dietary requirements. In this paper, we analyze past trends of food production and consumption in Africa, both for the continent as a whole and for 52 individual countries within it. Fluctuations in the self...

Application of meta-analysis in plant pathology: a case study examining the impact of fungicides on wheat yield loss from the yellow spot—septoria nodorum blotch disease complex in Western Australia

This work was done to demonstrate the opportunities provided by application of meta-analysis in plant pathology. It was a case study used to determine the effectiveness of foliar fungicides in minimising yield loss from a complex of yellow spot (Pyrenophora tritici-repentis) and septoria nodorum blotch (Stagonospora nodorum, teleomorph: Phaeosphaeria nodorum) (YS-SNB disease...

Adapting maize production to climate change in sub-Saharan Africa

Given the accumulating evidence of climate change in sub-Saharan Africa, there is an urgent need to develop more climate resilient maize systems. Adaptation strategies to climate change in maize systems in sub-Saharan Africa are likely to include improved germplasm with tolerance to drought and heat stress and improved management practices. Adapting maize systems to future...

Food security in South Africa—first steps toward a transdisciplinary approach

The Stellenbosch University Food Security Initiative provides a platform on which a range of research projects has been developed, spanning different faculties and departments, including the health sciences, agricultural sciences, engineering, and the social sciences. Drawing on a selection of these projects, some of which are published in a special section of this issue of Food...

The role of wild vegetable species in household food security in maize based subsistence cropping systems

Wild vegetables (WV) are an important source of food in the maize based subsistence farming sector of rural South Africa. Their main role is as relish as they are used as an accompaniment for staple cereal based diets. They are generally reported to be rich in micronutrients. Although they may be consumed in small quantities, they influence the intake of cereal staples, manage...

Mussel and oyster culture in Saldanha Bay, South Africa: potential for sustainable growth, development and employment creation

Worldwide declines in fish stocks have a significant impact on the livelihoods of coastal fishing communities as jobs are lost and alternative forms of employment are limited. Mariculture (marine aquaculture) is considered by governments to be a viable solution to address unemployment and poverty in such communities. In Saldanha Bay, South Africa, the growing mussel and oyster...

Food security in rural areas of Limpopo province, South Africa

Although South Africa is food secure as a nation, many households remain food insecure. The government has recognized several key food security challenges in the Integrated Food Security Strategy (IFSS). However, South Africa still lacks specific and accepted methods to measure food security and currently has no regulated way of monitoring the food security status of its...

Gamebirds: A sustainable food source in Southern Africa?

In order to alleviate the current food security situation the world is faced with, it is essential to investigate meat sources which have the potential to be used in a sustainable manner. This review provides substantial arguments to prove the viability of sport hunted wildfowl as a food source in Southern Africa. However, before the use of wildfowl meat can be realised, there...

Are food insecure smallholder households making changes in their farming practices? Evidence from East Africa

We explore the relationship between farming practice changes made by households coping with the huge demographic, economic, and ecological changes they have seen in the last 10 years and household food security. We examine whether households that have been introducing new practices, such as improved management of crops, soil, land, water, and livestock (e.g. cover crops, micro...

Gender, agricultural commercialization, and collective action in Kenya

With the commercialization of agriculture, women are increasingly disadvantaged because of persistent gender disparities in access to productive resources. Farmer collective action that intends to improve smallholder access to markets and technology could potentially accelerate this trend. Here, we use survey data of small-scale banana producers in Kenya to investigate the gender...

Shifting perceptions of food security and land in the context of labour out-migration in rural Nepal

This paper presents the results of a survey of the livelihoods of people living in the eastern part of the subtropical plains of Nepal, known as the terai. Both qualitative and quantitative approaches were used in the survey and further data were obtained through focus group discussions, in-depth interviews with key informants and participant observations. Changes were recorded...

Factors determining the adoption and impact of a postharvest storage technology

This paper evaluates the determinants and impact of adopting the metal silo—a postharvest storage technology for staple grains—which was disseminated by the Swiss Agency for Development and Cooperation (SDC) from 1983 to 2003 in four Central American countries. The aim of the SDC program was to diminish smallholder farmers’ postharvest losses by facilitating the manufacture and...

Land constraints in Kenya’s densely populated rural areas: implications for food policy and institutional reform

This study analyzes the impact of increasing population density in Kenya’s rural areas on smallholder behavior and welfare indicators. We first present evidence to explain how land constraints can be emerging within an overall context of apparent land under-utilization. Using data from five panel surveys on 1,146 small-scale farms over the 1997–2010 period, we use econometric...
