Genetically Modified Maize: Less Drudgery for Her, More Maize for Him? Evidence from Smallholder Maize Farmers in South Africa

Genetically modified (GM) crop technologies have made great strides since its first introduction in 1996. Although there is an extensive and growing body of literature on the economic impact of the adoption of GM crops in both developing and developed economies, there is only scant evidence that the technology has had any specific and distinguishable impact among female and male farmers. In economies where female farmers and female household members have a significant and often differentiated role in agriculture production, it is crucial to be able to answer this question.

Future climate impacts on maize farming and food security in Malawi

Agriculture is the mainstay of Malawi's economy and maize is the most important crop for food security. As a Least Developed Country (LDC), adverse effects of climate change (CC) on agriculture in Malawi are expected to be significant. We examined the impacts of CC on maize production and food security in Malawi's dominant cereal producing region, Lilongwe District. We used five Global Circulation Models (GCMs) to make future (2011 to 2100) rainfall and temperature projections and simulated maize yields under these projections.

Enhancing the Vitamin and Mineral Content of Wheat and Maize Through Plant Breeding

More than half of the world's population suffers micronutrient undernourishment. The main sources of vitamins and minerals (iron, zinc, and vitamin A) for low-income rural and urban populations are staple foods of plant origin that often contain low levels or low bioavailability of these micronutrients. Biofortification aims to develop micronutrient-enhanced crop varieties through conventional plant breeding.

Effects of the Farmer Support Programme and Changes in Marketing Policies on Maize Production in South Africa

This article analyses the effects of action aimed at narrowing the gap between South Africa's ‘two agricultures’, specifically the effects of the Farmer Support Programme (FSP) on structural aspects of maize production under different marketing policies. This is done by assembling a sectoral linear programming model of the South African summer-rainfall grain-producing area. The emphasis is on the inclusion of supply, demand and production risk. Results show that the effects of a successful FSP on specific interest groups, e.g.

Do the poor pay more for maize in Malawi?

The paper uses data from the Third Integrated Household Survey to examine whether or not the poor pay more for maize in Malawi. The paper finds that the poor in rural and urban areas pay more for maize. It is found that the poor pay more for maize irrespective of when the maize is purchased. Thus, seasonality does not seem to be behind the observed poverty penalty. The paper finds that the poverty penalty varies with seasonality; it is significantly more pronounced in the post-harvest period when maize is in abundance, it is, however, reduced in the lean season.

Corn

Corn (Zea mays L.), or maize as it is called in countries other than the USA, is one of the most important and most remarkable cereal crops in the world today. It is one of the world's most diverse crop species. No other cereal has a greater range of adaptability. It apparently originated in pre-Columbian times somewhere in Mexico and Central America from where it spread northward to Canada and southward to Argentina (Galinat, 1977, 1979).

Climate Change Adaptation Strategies of Maize Producers of the Central Rift Valley of Ethiopia

The impacts of climate change are considered to be strong in countries located in tropical Africa that depend on agri-culture for their food, income and livelihood. Therefore, a better understanding of the local dimensions of adaptationstrategies is essential to develop appropriate measures that will mitigate adverse consequences.

Bulk genetic characterization of Ghanaian maize landraces using microsatellite markers

Maize (Zea mays L) was first introduced into Ghana over five centuries ago and remains the most important cereal staple, grown in all agro-ecologies across the country. Yield from farmers’ fields are low, which is attributed in part to farmer’s preferences and/or reliance on local landraces for cultivation. Efforts are underway to improve some of these landraces for improved productivity. Seeds of maize landraces cultivated in all agro-ecologies were collected for genetic characterization using a bulked fingerprinting technique and 20 SSR markers.

Assessing the Potential of Dual-Purpose Maize in Southern Africa: A Multi-Level Approach

This paper explores the potential and challenges of increasing production of food and feed on existing maize fields in mixed crop-livestock systems in the semi-arid areas of southern Africa. It integrates results from different sources of data and analysis: 1. Spatial stratification using secondary data for GIS layers: Maize mega-environments combined with recommendation domains for dual-purpose maize were constructed for Malawi, Mozambique and Zimbabwe, stratifying the countries by demand factors (livestock densities and human population densities) and feed availability.

Adoption and Impacts of Sustainable Agricultural Practices on Maize Yields and Incomes: Evidence from Rural Zambia

This paper uses a multinomial endogenous treatment effects model and data from a sample of over 800 households and 3,000 plots to assess the determinants and impacts of adoption of sustainable agricultural practices (SAPs) on maize yields and household incomes in rural Zambia. Results show that adoption decisions are driven by household and plot level characteristics and that the adoption of a combination of SAPs raises both maize yields and incomes of smallholder farmers.
