Refining the smallholder market integration framework : A qualitative study of Ethiopian pastoralists

Ethiopia - Market integration - Market integration framework - Market participation - Pastoralists

The continued interest in market access and market integration policies targeting small-scale agricultural producers has led researchers to further explore the theoretical underpinnings of these concepts. This study presents an in-depth qualitative investigation into the behavioral consequences of market integration for Ethiopian pastoralists. The findings show that pastoralists further strengthen their strategic connection to the market by the processes of market sensing and market responding, which enable them to offer livestock with the quality attributes demanded by buyers. Pastoralists engaging in these activities typically generate more revenue from the market, thereby improving their livelihoods. They are also more capable of adapting to changes in natural conditions and are more likely to change their lifestyles. These findings imply that policymakers should not only foster the market participation of small-scale agricultural producers, but also ensure that producers align their products with the wants and needs of customers by sensing and responding to their market.

Calcium adsorption - Phosphate adsorption - Regeneration - Reusability - Surface precipitation - Wastewater effluent

Phosphate is a vital nutrient for life but its discharge from wastewater effluents can lead to eutrophication. Adsorption can be used as effluent polishing step to reduce phosphate to very low concentrations. Adsorbent reusability is an important parameter to make the adsorption process economically feasible. This implies that the adsorbent can be regenerated and used over several cycles without appreciable performance decline. In the current study, we have studied the phosphate adsorption and reusability of commercial iron oxide based adsorbents for wastewater effluent. Effects of adsorbent properties like particle size, surface area, type of iron oxide, and effects of some competing ions were determined. Moreover the effects of regeneration methods, which include an alkaline desorption step and an acid wash step, were studied. It was found that reducing the adsorbent particle size increased the phosphate adsorption of porous adsorbents significantly. Amongst all the other parameters, calcium had the greatest influence on phosphate adsorption and adsorbent reusability. Phosphate adsorption was enhanced by co-adsorption of calcium, but calcium formed surface precipitates such as calcium carbonate. These surface precipitates affected the adsorbent reusability and needed to be removed by implementing an acid wash step. The insights from this study are useful in designing optimal regeneration procedures and improving the lifetime of phosphate adsorbents used for wastewater effluent polishing.

As the world population is expected to expand beyond 9 billion by 2050, food production will need to increase by approximately 70% to feed the population. Furthermore, a growing part of that expanding population pertains to an upcoming middle class, leading to an increasing demand for high-value products, animal protein and safer food. To respond to this growing demand in terms of quantity and quality, supply chains are pushing market-frontiers deeper into the rural areas in developing and emerging markets to secure their supplies. As a consequence, rural smallholders including pastoralists, who have been functioning at local markets, are increasingly integrating with international markets. While such integration opens opportunities for the smallholders to access higher purchasing power, it is difficult for remote and isolated pastoralists with limited productive resources and limited institutional support to recognize and seize the opportunities. Because pastoralists are mostly isolated from the other value chain members, they have not developed the knowledge regarding how the market functions and what the value chain members want. By conducting a field experiment among a group of Ethiopian pastoralists, this thesis shows that marketing training is an important approach in enhancing the market knowledge of pastoralists that enable them to understand the market environment, to reproduce their animals as per market requirements and to generate returns. The thesis also has implications for other rural smallholders that share similar characteristics with the pastoralists.

Moving Toward New Horizons for Marketing Education : Designing a Marketing Training for the Poor in Developing and Emerging Markets

customer value - developing and emerging markets - marketing training - pastoralists - poverty

In recent years, marketing education has broadened to poor people in developing and emerging countries. In this article, the authors use four empirical studies that apply well-established training design procedures to design a marketing training program for Ethiopian pastoralists. Because pastoralists operate in extremely remote, traditional, and sparsely populated regions of developing and emerging markets, the training complements trainings for the poor applied in urban areas of these countries. As such, the article provides implications for training program designers on how they can adapt the training program procedures to other contexts, thereby making marketing ideas accessible to a large and important new target group for marketing education.
