Quality and value chain analyses of Ethiopian coffee

The objective of this paper is to analyze the quality and value chain of Ethiopian coffee in a way to identify opportunities that maximize the benefits from the sector. First the Ethiopian coffee sector is overviewed and then analyzed qualitatively and quantitatively starting from the crop up to the cup based on data collected from secondary sources. As a result, in spite of the comparative advantage in flavor, the Ethiopian green coffee price in the international market is lower than other countries’ price. In addition, actors are not fairly priced because of quality and value addition. The causes for poor quality are mainly associated with harvesting and post-harvesting practice including collection, dry and wet processing, storage and transportation. The value chain actors will play a critical role to increases the profit plow back in the Ethiopian coffee sector and then will significantly improve living standards of the poor who are at the source of the chain.Key words – Coffee, Quality, Value additio

Ion exchanges in apatites. Effects on composition and properties

The modification of the composition of apatites materials can be made by several processes corresponding to ion exchange reactions which can conveniently be adapted to current coatings and ceramics and are an alternative to the set up of new synthesis methods. In addition to high temperature thermal treatments, which allow to virtually replace partly or totally monovalent OH- anion of stoichiometric hydroxyapatite by any halogen ion or carbonate, aqueous processes corresponding to dissolution-reprecipitation reactions have also been proposed and used. The most interesting possibilities are however provided by aqueous ion exchange reactions involving nanocrystalline apatites. These apatites are characterised by the existence on the crystal surface of a hydrated layer of loosely bound mineral ions which can be easily exchanged in solution. This layer offers a possibility to trap mineral ions and possibly active molecules which can modify the apatite properties. Such processes are involved in mineralised tissues and could be used in biomaterials for the release of active mineral species

A Behavioral Change Perspective of Maroon Soil Fertility Management in Traditional Shifting Cultivation in Suriname

In Suriname, the Maroons have practiced shifting cultivation for generations, but now the increasing influence of modern society is causing a trend of decreasing fallow periods with potentially adverse effects for the vulnerable tropical soils. Adoption of appropriate soil fertility management (SFM) practices is currently slow. Combining methods from cultural ecology and environmental psychology, this study identifies two groups with divergent behavioral intentions which we term semi-permanent cultivators and shifting cultivators. Semi-permanent cultivators intend to practice more permanent agriculture and experiment individually with plot-level SFM. Shifting cultivators rely on traditional knowledge that is not adequate for their reduced fallow periods, but perceive constraints that prevent them practicing more permanent agriculture. Semi-permanent cultivators act as a strong reference group setting a subjective norm, yet feel no need to exchange knowledge with shifting cultivators who are in danger of feeling marginalized. Drawing on a political ecology perspective, we conclude that cultural ecological knowledge declined due to negative perceptions of external actors setting a strong subjective norm. Semi-permanent cultivators who wish to enter the market economy are most likely to adopt SFM. We conclude that any future SFM intervention must be based on an in-depth understanding of each group’s behavior, in order to avoid exacerbating processes of marginalization

A framework for scabies control.

Scabies is a neglected tropical disease (NTD) that causes a significant health burden, particularly in disadvantaged communities and where there is overcrowding. There is emerging evidence that ivermectin-based mass drug administration (MDA) can reduce the prevalence of scabies in some settings, but evidence remains limited, and there are no formal guidelines to inform control efforts. An informal World Health Organization (WHO) consultation was organized to find agreement on strategies for global control. The consultation resulted in a framework for scabies control and recommendations for mapping of disease burden, delivery of interventions, and establishing monitoring and evaluation. Key operational research priorities were identified. This framework will allow countries to set control targets for scabies as part of national NTD strategic plans and develop control strategies using MDA for high-prevalence regions and outbreak situations. As further evidence and experience are collected and strategies are refined over time, formal guidelines can be developed. The control of scabies and the reduction of the health burden of scabies and associated conditions will be vital to achieving the targets set in WHO Roadmap for NTDs for 2021 to 2030 and the Sustainable Development Goals

Innovation Systems in Agriculture and Rural Development

Much has been written on innovation systems (IS), especially in industrialized economies, and recently in developing countries contexts (Muchie et al., 2003; Hall 2005; Spielman et al., 2006; World Bank 2007). However, with few exceptions (e.g., Hall 2005; Hall et al., 2007; World Bank 2007), literature on IS does not adequately explain how system thinking enhances innovation or how IS can be initiated and facilitated. Another gap is the fact that “innovation” itself is promoted rather than its embeddedness within a system that in turn operates within certain institutional and policy contexts. Even though there is consensus on the importance of innovation for economic development, the systemic mechanism through which it can be enhanced is not given equal attention. These and other grey areas limit the promotion of the concept of IS, and in a worst case raises suspicion on its value addition for research and development

Systèmes d’innovation au service du développement agricole et rural

Les systèmes d’innovation (SI) ont inspiré de nombreuses publications, notamment dans les pays industrialisés et, plus récemment, dans le monde en développement. Toutefois, à quelques exceptions près, la littérature dédiée aux SI n’explique pas de manière appropriée comment utiliser l’approche systémique pour améliorer l’innovation ou comment initier et faciliter les SI. Par ailleurs, si l’innovation elle-même semble avoir été suffisamment étudiée, son intégration dans un système qui, à son tour, opère dans certains contextes institutionnels et politiques, n’a pas été approfondie. Si l’on reconnaît l’importance de l’innovation pour le développement économique, le mécanisme systémique qui peut aider à renforcer la dynamique d’innovation ne fait pas l’objet d’une attention similaire. Ces zones d’ombre, entres autres, ne permettent pas de juger de la pertinence du concept de SI et, dans le pire des cas, tendent à remettre en cause ses potentialités pour la recherche et le développement
