In order to address food insecurity, the New Green Revolution for Africa (GR4A) promotes tighterintegration of African smallholder farmers, especially women, into formal markets via value chains to improve farmers’ input access and to encourage the sale of crop surpluses. This commentary offers a theoretical and practical critique of the GR4A model, drawing on early findings from a five-year study of value chain initiatives in Burkina Faso, Côte d’Ivoire, and Mozambique.

This paper provides a retrospective look at a systems-oriented research program, on the increasing occurrence of parasitic weeds in rainfed rice in sub-Saharan Africa, to qualitatively assess merits and identify challenges of such approach. Was gained a broad contextual overview of the problem and different stakeholders' roles, which enabled identification of entry points for innovations in parasitic weed management

Farm workers in developing countries often belong to the poorest of the poor. They typically face low wages, informal working arrangements, and inadequate social protection. Written employment contracts with clearly defined rights and obligations could possibly help, but it is not clear how such contracts could be introduced and promoted in traditional peasant environments. To address this question, we develop and implement a randomized controlled trial with farmers in Côte d’Ivoire.

Fairtrade certification has recently gained in importance for various export crops produced in developing countries. One of Fairtrade's main objectives is to improve the social conditions of smallholder farmers. Previous research showed that Fairtrade has positive effects on farmers' sales prices and incomes in many situations. However, more detailed analysis of the effects on food security and other dimensions of household living standard is rare.

It is often assumed that voluntary sustainability standards – such as Fairtrade – could not only improve the socioeconomic wellbeing of smallholder farmers in developing countries but could also help to reduce negative health and environmental impacts of agricultural production. The empirical evidence is thin, as most previous studies on the impact of sustainability standards only focused on economic indicators, such as prices, yields, and incomes.

Written employment contracts may improve the conditions of agricultural workers in developing countries, but farmers as employers often prefer less formal oral arrangements. We evaluate whether farmers’ preferences, which are deeply rooted in traditional norms, can be influenced through a group awareness campaign. In a randomised experiment in Côte d’Ivoire, we show that such a campaign increases farmers’ preferences for written contracts and for contract features involving social benefits for workers.

This paper compares lessons learned from nine studies that explored institutional determinants of innovation towards sustainable intensification of West African agriculture. The studies investigated issues relating to crop, animal, and resources management in Benin, Ghana, and Mali.The studies showed that political ambitions to foster institutional change were often high (restoring the Beninese cotton sector and protecting Ghanaian farmers against fluctuating cocoa prices) and that the institutional change achieved was often remarkable.

Based on international literature, preliminary experiences in a three-country West African research programme, and on the disappointing impact of agricultural research on African farm innovation, the current paper argues that institutional change demands rethinking the pathways to innovation so as to acknowledge the role of rules, distribution of power and wealth, interaction and positions. The time is opportune: climate change, food insecurity, high food prices and concomitant riots are turning national food production into a political issue also for African leaders.

In 2008, an NGO showed videos about rice to farmers in 19 villages in Benin. A study in 2013 showed that farmers remembered the videos, even after five years had passed. In most of the villages at least some farmers experimented with rice farming or with new technology after the video screenings, which attracted large audiences of community members, including youth and women. Some of the villagers also visited extension agencies to get rice seed, and occasionally to seek more information.
