| Climate change increases the number of risks for agricultural production in arid and semiarid regions, especially in Western Africa. Smallholder farmers are particularly vulnerable to climate change risks. These risks affect their socioeconomic situation, as well as the local food sector value chain in general. Therefore, their food security is threatened if smallholder farming structures do not adapt to them. Thus, effective climate change adaptation measures for smallholders are essential and should be implemented without delay. However, success hinges on the acceptance of the promoted measures among various stakeholders. Thus, their acceptance needs to be assessed before promoting. The project “The potential of sustainable land-use systems to promote... |

| Cassava production has grown rapidly in Zambia since the early 1990’s. Available evidence suggests that volumes of traded cassava have been increasing roughly twice as fast as production. Yet this cassava production boom could stall unless commercial markets for it develop. To help accelerate commercial development of cassava and cassava-based products at the national level, Zambia’s Agricultural Consultative Forum (ACF) initiated an Acceleration of Cassava Utilization (ACU) Task Force, beginning in August 2005. At a regional level, efforts such as the Cassava Transformation in Southern Africa (CATISA) project aim to complement national efforts and help facilitate regional spillovers, so that new products, new technologies or new lessons can help to... |

| This is the first of a series of papers that review the state of knowledge and practice regarding compensation and rewards for environmental services in the developing world. The paper begins with an assessment of the historical development of compensation and reward mechanisms within a broader context of changing approaches to nature conservation and environmental policy. The assessment shows that greater interest in compensation and reward mechanisms has emerged within a policy context of changing approaches to nature conservation and flexible multi-stakeholder approaches to environmental management. In the developing world, an even greater variety of perspectives has emerged on the opportunities and threats for using compensation and rewards for... |

| Decades of research on the social dynamics of biodiversity conservation has shown that parks and protected areas have added hardship to rural communities throughout much of the developing world. Nonetheless, some recent studies have found evidence of poverty alleviation near protected areas. To build on these conflicting accounts, I use a comparative, mixed-methods design to examine opportunistic, unplanned, i.e., unscripted, development in indigenous communities near Tarangire National Park (TNP) in northern Tanzania. I ask the questions: (1) How is proximity to TNP related to community-level infrastructural development? (2) How has the process of development changed over time? and (3) How is proximity to TNP related to infrastructure-related social... |

| The development of agricultural commodity exchanges in Africa has become an increasingly popular strategy for addressing some of the ills plaguing African food markets, including poorly developed risk management systems, high transaction costs, and limited price discovery. However, despite substantial support from donors and, in some cases, national governments, commodity exchanges in most African countries are having difficulties getting off the ground. While previous studies (Rashid, Winter-Nelson, and Garcia 2010) highlight the fact that low trade volumes passing through African commodity exchanges limit their development, the question of why exchanges are thinly traded remains poorly understood. Using the Zambian Agricultural Commodity Exchange... |

| This study describes the findings from a consumer survey that was conducted to understand the consumer characteristics and preferences for organic products in Kampala, Uganda. The survey used a mall intercept survey method to investigate consumer revealed preferences for key organic and conventional products attributes. A face-to-face interview was used to collect data on consumer preferences towards organic food attributes that reveals preference for specific organic and conventional products. The survey was conducted in two purely organic retail outlets in Kampala as well as from consumer outlets that sell conventional alongside few organic products. A sample of 228 respondents was interviewed. An empirical analysis of the factors that influenced... |

| A survey of 600 consumers was conducted in Nairobi to determine attitudes and willingness to pay (WTP) for GM maize meal. WTP was estimated using the double-bounded logit model. Overall, 38% are aware of GM crops. Most consumers believe in the technology's positive impacts, but are concerned about environmental and health risks. Majority (68%) would buy GM maize meal at the price of their favourite maize meal brand. The mean WTP for GM maize meal is KShs 58 for a 2kg packet, a premium of 13.7 % over mean average price of favourite brands. WTP is influenced more by subjective than socioeconomic characteristics. |

| Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent... |

| This study investigates the seismic structure and anisotropy in the crust beneath Madagascar and south-eastern Africa, using receiver functions. The understanding of seismic anisotropy is essential for imaging past and present deformation in the lithosphere-asthenosphere system. In the upper mantle, seismic anisotropy mainly results from the orientation of olivine, which deforms under tectonic (fossil anisotropy) or flow processes (in the asthenosphere). In the crust, the crystallographic alignment of amphiboles, feldspars(plagioclase) or micas or the alignment of heterogeneities such as fractures, add to a complex geometry, which results in challenges to understanding the Earth's shallow structure. The decomposition of receiver functions into back-azimuth... |

| We determine the deep structure of the eastern Algerian basin and its southern margin in the Annaba region (easternmost Algeria), to better constrain the plate kinematic reconstruction in this region. This study is based on new geophysical data collected during the SPIRAL cruise in 2009, which included a wide-angle, 240-km-long, onshore–offshore seismic profile, multichannel seismic reflection lines and gravity and magnetic data, complemented by the available geophysical data for the study area. The analysis and modelling of the wide-angle seismic data including refracted and reflected arrival travel times, and integrated with the multichannel seismic reflection lines, reveal the detailed structure of an ocean-to-continent transition. In the deep basin,... |

| Ethiopia holds large potential for dairy development due to its large livestock population, the favorable climate for improved, high-yielding animal breeds, and the relatively disease-free environment for livestock. Given the considerable potential for smallholder income and employment generation from high-value dairy products, development of the dairy sector in Ethiopia can contribute significantly to poverty alleviation and nutrition in the country. Like other sectors of the economy, the dairy sector in Ethiopia has passed through three phases or turning points, following the economic and political policy in the country. In the most recent phase, characterized by the transition towards market-oriented economy, the dairy sector appears to be moving... |

| Les études en agriculture écologique et biologique montrent très peu d’intérêt aux questions langagières en général et celles des femmes en particulier en considérant à tort ou à raison les travaux linguistiques comme non adéquates en agriculture. Toutefois, la langue se trouve au cœur de toute discipline et c’est qui nous motive lorsque nous nous intéressons au discours de femmes qui s’investissent dans ce mode de production. Au Bénin, les femmes rurales sont au cœur des systèmes de production agricole où elles jouent des rôles primordiaux. Néanmoins, à l’heure de s’exprimer, elles sont reléguées au second rang et deviennent des invisibles et des sans voix. Ceci revient au fait que si la femme doit parler, étant la propriété privée d’un homme, cet homme... |
