Role of Farmers’ Personal Values in Soil Fertility Management Decisions: Evidence from Means-End Chain Analysis of Peri-urban Leafy Vegetable Production in Kenya Okello, Julius J.; Lagervisk, Carl Johan; Ngigi, Marther; Karanja, Nancy Peri-urban areas play a major role in the supply of vegetables consumed in urban areas. In order to meet high demand for aesthetic quality characteristics, peri-urban farmers use intensive production practices characterized by use external inputs. This paper uses Means-End Chain analysis approach to examine the role farmers’ personal values play in the decision to use soil fertility improvement inputs namely, animal manures (organic fertilizer) and inorganic fertilizers. It found that use of animal manures and inorganic fertilizers was driven by the need to earn higher profit margins thus making more money in order to meet family needs. This in turn met farmers’ personal values relating to, among others, happiness, leading a comfortable life, independence and healthy life. The major implication of these findings was that farmers’ private goals could, with the urging of the market that demands unique aesthetic quality characteristics, promote intensive applications of both the organic and inorganic inputs with potential negative environmental consequences.

Shocks, livestock assets and climate change adaptation in Kenya Ngigi, Marther W.; Birner, Regina The study assesses the impact of shocks on livestock and the role of adaptation to climate change in protecting assets from weather shocks. Data collection relied on a mixed-method approach, including household surveys and participatory rural appraisals (PRAs) in each site. The study uses panel data collected in 2009 and 2012 and a total of 362 balanced panels are used in the study. The study uses fixed effect models in analysis. The findings show that shocks have a negative effect on livestock. Small and large animals are affected differently by different shocks. Large livestock are mostly affected by droughts while market shocks affect small animals. The study also finds that land ownership and income positively affect livestock assets. With regard to adaptation to climate change, farmers who are adapting to changing climate are resilient to weather shocks. Membership in community-based organizations help households in accumulating livestock assets, and this suggests the importance of local institutions in risk management. The study also discusses policy implications.

Asynchronous interconnection of the proposed East Africa Power Pool (EAPP) Musau, Moses Peter; Abungu, Nicodemus Odero; Wekesa, Cyrus Wabuge East Africa Power Pool (EAPP) is a proposed regional interconnection for centralizing energy resources and facilitating power wheeling between the Eastern Africa geographical areas. Synchronous tie lines have been used in the established interconnections so far. However, asynchronous interconnection is preferred since there high Renewable Energy (RE) penetration in the EAPP. HVDC technology, particularly multi terminal DC (MTDC) is a good example of such links as it provides loose coupling between the interconnected power systems. This has several economic ,environmental and security-stability merits as compared to the traditional HVAC tie lines. The Kenya-Ethiopia HVDC Bipolar is supposed to provide a loose coupling between the two countries. The same technology can be reproduced in the EAPP so as to achieve a dynamic regional interconnection. Thus, a 10-Area system with 18 MTDC tie lines is considered where each area represents a Transmission System Operator (TSO) for each country. In this paper, a multi area multi objective economic dispatch (MAMODED) with RE and Emissions is formulated where MTDC constraints have been included for the first time in the EAPP. Review of EAPP and MAMODED with RE, merits of MTDC interconnection, RE penetration in EAPP, and MTDC tie line power flows are also presented.
