This study aims to explore how the Positive Deviance approach can be adapted to identify and prioritize rural development interventions for diverse farming households that pursue multiple objectives. We describe the adapted approach, consisting of three research steps, and a case study implementation in Tanzania. Based on this experience, the potential of the Positive Deviance approach for household-specific prioritization of multi-objective development opportunities is discussed
The use of mobile phones has increased rapidly in many developing countries, including in rural areas. Besides reducing the costs of communication and improving access to information, mobile phones are an enabling technology for other innovations. One important example are mobile phone based money transfers, which could be very relevant for the rural poor, who are often underserved by the formal banking system. We analyze impacts of mobile money technology on the welfare of smallholder farm households in Kenya.
Many of the world’s food-insecure and undernourished people are smallholder farmers in developing countries. This is especially true in Africa. There is an urgent need to make smallholder agriculture and food systems more nutrition-sensitive. African farm households are known to consume a sizeable part of what they produce at home. Less is known about how much subsistence agriculture actually contributes to household diets, and how this contribution changes seasonally. We use representative data from rural Ethiopia covering every month of one full year to address this knowledge gap.
The role of genetically modified (GM) crops for food security is the subject of public controversy. GM crops could contribute to food production increases and higher food availability. There may also be impacts on food quality and nutrient composition. Finally, growing GM crops may influence farmers’ income and thus their economic access to food. Smallholder farmers make up a large proportion of the undernourished people worldwide. Our study focuses on this latter aspect and provides the first ex post analysis of food security impacts of GM crops at the micro level.
Productivity growth in smallholder agriculture is an important driver of rural economic development and poverty reduction. However, smallholder farmers often have limited access to information, which can be a serious constraint for increasing productivity. One potential mechanism to reduce information constraints is the public agricultural extension service, but its effectiveness has often been low in the past.
Land-use changes have dramatically transformed tropical landscapes. We describe an ecological-economic land-use change model as an integrated, exploratory tool used to analyze how tropical land-use change affects ecological and socio-economic functions. The model analysis seeks to determine what kind of landscape mosaic can improve the ensemble of ecosystem functioning, biodiversity, and economic benefit based on the synergies and trade-offs that we have to account for.
Mobile phone use is increasing in Sub-Saharan Africa, spurring a growing focus on mobile phones as tools to increase agricultural yields and incomes on smallholder farms. However, the research to date on this topic is mixed, with studies finding both positive and neutral associations between phones and yields. In this paper we examine perceptions about the impacts of mobile phones on agricultural productivity, and the relationships between mobile phone use and agricultural yield.
Les espaces ruraux périurbains des grandes villes d'Algérie vivent des transformations liées à trois facteurs combinés, parfois contradictoires : l'ouverture libérale, la redistribution de la rente pétrolière et l'évolution des espaces et des marchés urbains. Les exemples de la Mitidja centrale (entre Blida et Alger) et de l'Oranais en révèlent la diversité et les contrastes.
La sécurité alimentaire en Algérie semble plus que menacée par un niveau de croissance démographique incontrôlé, par la dégradation des conditions physiques du secteur de l’agriculture, par la baisse des ressources hydriques et par le retard de développement technique de l’activité. À partir d’une revue bibliographique sur la situation actuelle du secteur agricole, le texte définit ses niveaux de développement et les défis de l’avenir auxquels ce secteur sera confronté.
Les grandes exploitations agricoles créées dans le cadre de la loi de mise en valeur agricole de 1983 dans le Sahara algérien étaient vouées à une production céréalière sous pivot. L’objectif était de développer économiquement des régions sahariennes pour partie marginalisées, ainsi que de réduire la dépendance chronique en céréales du pays. L’État a considérablement investi pour équiper ces exploitations agricoles dans le cadre d’un vaste plan de développement rural. Mais trente ans après la parution de la loi, les réalisations demeurent limitées au regard des objectifs initiaux.
