The effect of education on household food security in two informal urban settlements in Kenya: a longitudinal analysis

Poverty and food insecurity continue to feature prominently in the global agenda, with particularly close attention being paid to the determinants of food insecurity. However, the effect of education is mixed and remains understudied in low income countries. Using longitudinal data collected between 2007 and 2012 in Kenya, we investigated the effect of household education ...

Exploring the role of social capital in influencing knowledge flows and innovation in smallholder farming communities in the Caribbean

This paper presents the results of an exploratory study into how different forms of social capital embedded within community-based social networks may affect innovation in smallholder farming systems to better support food security in the Caribbean. Focusing on two rural communities in the small island developing nation of Saint Lucia, our results indicate the strong presence of ...

Attitudes toward genetically modified organisms in Poland: to GMO or not to GMO?

Genetically modified organisms (GMOs) are a subject of on-going scientific, political and social discussions in Member States of the European Union (EU) concerning their use, benefits, risks, safety and limitations. EU societies have every right to substantive information and education in biotechnology, yet they appear to be misinformed by contradictory views and sensationalism. ...

Quantifying ambivalence towards sustainable intensification: an exploration of the UK public’s values

Sustainable intensification (SI) has been proposed as a solution to meeting the challenge of feeding a growing global population under increasing land pressure. This paper explores the level of ambivalence felt towards SI and towards experts promoting SI based solutions to meet food security. A web-based experiment was conducted with 600 respondents who had varying degrees of ...

Phosphorus recycling and food security in the long run: a conceptual modelling approach

Food security for all is a global political goal and an outstanding moral concern. The common response to this concern is agricultural intensification, which includes among other things increasing inputs of fertilisers. The paper addresses the fact that phosphorus (P) is essential for agricultural production but large and increasing amounts of P fertilisers stem from depletable ...

Using a plant health system framework to assess plant clinic performance in Uganda

Systems thinking is commonly applied to understand the complexities of human healthcare delivery. In contrast, plant health systems as an organising principle have evolved more recently from work with plant clinics as providers of plant healthcare services to farmers. As plant health systems evolve and expand, new analytical frameworks and tools are needed to identify factors ...

Seed systems smallholder farmers use

Seed can be an important entry point for promoting productivity, nutrition and resilience among smallholder farmers. While investments have primarily focused on strengthening the formal sector, this article documents the degree to which the informal sector remains the core for seed acquisition, especially in Africa. Conclusions drawn from a uniquely comprehensive data set, 9660 ...

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 water ...

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 that ...

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 metric ...

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 type ...

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 ...
