Managing risks from pests in global commodity networks – policy perspectives

Up to 80 % of global commodity production comes from smallholdings of less than 0.5 ha. Yet commodity crops may be a substantial proportion of a country’s exports, and feed into global supply networks. Pest risks thus have consequences at local, national and global levels. We consider three categories of risk in global commodity networks: introduction of pests to new areas...

South-South cooperation: Brazilian soy diplomacy looking East?

Ever since the food price crisis of 2007/8, concerns about global food supply interruptions have mounted. However, while exports from Brazil, the world’s leading soy exporter, are currently under threat, this is not due to geopolitical concerns, but due to resource mismanagement. As a consequence, the country with the most water availability per person is mired in an enduring...

Subsidies promote use of drought tolerant maize varieties despite variable yield performance under smallholder environments in Malawi

This study used a three-year panel dataset for 350 Malawian farm households to examine the potential for widespread adoption of drought tolerant (DT) maize varieties, a technology that holds considerable promise for helping smallholder farmers in Sub-Saharan Africa (SSA) adapt to drought risk. Regression results revealed that DT maize cultivation increased substantially from 2006...

Zero-tillage as a pathway for sustainable wheat intensification in the Eastern Indo-Gangetic Plains: does it work in farmers’ fields?

In controlled-condition field trials across South Asia, zero-tillage (ZT) has demonstrated considerable scope for enhancing wheat productivity in the Indo-Gangetic Plains (IGP) while using less energy and irrigation water. However, studies that quantify the impact of ZT in farmers’ fields are scarce, especially in the less productive and densely populated Eastern IGP, an area...

Factors that transformed maize productivity in Ethiopia

Maize became increasingly important in the food security of Ethiopia following the major drought and famine that occurred in 1984. More than 9 million smallholder households, more than for any other crop in the country, grow maize in Ethiopia at present. Ethiopia has doubled its maize productivity and production in less than two decades. The yield, currently estimated at >3...

Labour not land constrains agricultural production and food self-sufficiency in maize-based smallholder farming systems in Mozambique

Despite abundant land and favourable climatic conditions, Mozambique remains food insecure. We investigated the diversity, constraints and opportunities to increase smallholder productivity and achieve food self-sufficiency in maize-based farming systems in two Posts in central Mozambique. We identified four farm types in each village based on cultivated area and labour. Farm...

Environmental impacts and constraints associated with the production of major food crops in Sub-Saharan Africa and South Asia

Many environmental factors constrain the production of major food crops in Sub-Saharan Africa and South Asia. At the same time, these food production systems themselves have a range of negative impacts on the environment. In this paper we review the published literature and assess the depth of recent research (since 2000) on crop x environment interactions for rice, maize...

Improved propagation methods to raise the productivity of yam (Dioscorea rotundata Poir.)

White Guinea yam (Dioscorea rotundata Poir.) is an important staple to millions of people in West Africa. Obtaining good quality planting material for yam cultivation is a major challenge. Multiplication ratios are low, and seed tubers are prone to contamination with pests and pathogens in the traditional systems of production. Some approaches to producing quality seed of yam are...

Farmers’ willingness to pay for a village poultry vaccine service in Ethiopia: prospect for enhancing rural livelihoods

This research examines farmers’ willingness to pay for village poultry vaccine programmes using data from 400 household heads from two districts in Ethiopia, Horro and Jarso. The study applied a contingent valuation method to elicit farmers’ willingness to pay for village poultry vaccine services. Two hypothetical vaccine programmes were designed for Newcastle disease and Gumboro...

The short-term impact of price shocks on food security-Evidence from urban and rural Ethiopia

This study investigates the impact of food price changes on food security in urban and rural Ethiopia. Using a quarterly household survey panel dataset and price data collected directly at markets, a negative effect of high cereal prices on some, but not all considered indicators of food security was found, controlling for unobserved heterogeneity across households. The results...

International agricultural research to reduce food risks: case studies on aflatoxins

Despite massive expansion of human and livestock populations, fuelled by agricultural innovations, nearly one billion people are hungry and 2 billion are sickened each year from the food they eat. Agricultural and food systems are intimately connected to health outcomes, but health policy and programs often stop at the clinic door. A consensus is growing that the disconnection...

Leveraging agriculture for nutrition in South Asia and East Africa: examining the enabling environment through stakeholder perceptions

South Asia and sub-Saharan Africa are the two regions of the world with the highest concentration of undernutrition. The majority of the nutritionally vulnerable populations in both regions is dependent in some way upon agriculture as a primary source of livelihood. The agriculture sector and wider agri-food system is considered to be central to sustained progress in reducing...

Agricultural policy and nutrition outcomes – getting beyond the preoccupation with staple grains

There is a growing disconnect between agricultural policy and contemporary nutritional challenges, the persistent problem of micronutrient malnutrition and child stunting, as well as the emerging challenges of overweight and obesity. Diversification of production systems and the market supply of enhanced diversity will only happen when the current distortions to farm and market...

Agricultural research for nutrition outcomes – rethinking the agenda

Agriculture and food are assumed to be critical determinants of stunting and micronutrient deficiency. However, agriculture research for development has not translated as expected into better nutrition outcomes. We argue that to do so, agriculture research needs to be fundamentally changed, from the current emphasis on supply-side production and productivity goals to...

Developing country consumers’ acceptance of biofortified foods: a synthesis

The success of biofortified staple crops depends on whether they are accepted and consumed by target populations. In the past 8 years, several studies were undertaken to understand consumers’ acceptance of foods made with biofortified staple crops. Consumer acceptance is measured in terms of their sensory evaluation and economic valuation of biofortified varieties vis-à-vis...

Urbanization, market development and malnutrition in farm households: evidence from the Demographic and Health Surveys, 1986–2011

A principal effect of agricultural productivity growth is to accelerate urbanization by supplying food, labor and other resources to urban services and industry. Towns and cities may also grow for their own reasons, pulling food and resources out of rural areas. Whether pushed or pulled, the development of markets creates new opportunities for agricultural households. This study...

Improving diets with wild and cultivated biodiversity from across the landscape

This paper examines the literature on how biodiversity contributes to improved and diversified diets in developing countries. We assess the current state of evidence on how wild and cultivated biodiversity in all forms is related to healthy diets and nutrition, and examine how economic factors, knowledge and social norms interact with availability of biodiversity to influence...

The food environment, its effects on dietary consumption, and potential for measurement within agriculture-nutrition interventions

The food environment in markets constrains and signals consumers what to purchase. It encompasses availability, affordability, convenience, and desirability of various foods. The effect of income on dietary consumption is always modified by the food environment. Many agricultural interventions aim to improve incomes, increase food availability and reduce food prices. Their...

The food security continuum: a novel tool for understanding food insecurity as a range of experiences

The current lack of consensus on the relationships between hunger, malnutrition and food insecurity frustrates efforts to design good policies and programs to deal with the many problems. Disputes over terminology distract from the need for urgent action. This paper argues that our understanding of food insecurity is incremental: it develops as new research in a variety of food...
