This study used choice experiment survey data from a random sample of 374 respondents to analyze consumer preferences for quality and safety attributes of artisanal fruit juices in Kenya. Results show that consumers had a positive and significant preference for single fruit juices compared to fruit mixtures, private rather than public inspection of the juices, traceability of fruit origin, and vendor’s health. Additives such as colorants, flavors, and preservatives were not preferred. Consumers were willing to pay premiums of up to 200% for artisanal juices that contain single fruits, lack additives, and are inspected by private agencies. These insights should be incorporated in ensuring that artisanal fruit juice designs comply with food quality and safety requirements. Further, there is a need to license and regulate the artisanal juice preparation and handling and to provide training to the handlers on safety and quality requirements.  相似文献

Management of livestock diseases is important in ensuring food safety to consumers in both domestic and export markets. Various measures are prescribed under the Sanitary and Phytosanitary Standards (SPS) agreement of the World Trade Organization. In order to prevent the spread of trans‐boundary cattle diseases, the SPS agreement recommends the establishment of Disease‐Free Zones (DFZs). These have been implemented successfully in some major beef‐exporting countries, but in Kenya are still at a pilot stage. To understand Kenyan farmers’ preferences on the type of DFZ that would be readily acceptable to them, a choice experiment was conducted using a D‐optimal design. Results show that farmers would be willing to pay to participate in a DFZ where: adequate training is provided on pasture development, record keeping and disease monitoring; market information is provided and sales contract opportunities are guaranteed; cattle are properly labelled for ease of identification; and some monetary compensation is provided in the event that cattle die due to severe disease outbreaks. Preferences for the DFZ attributes are shown to be heterogeneous across three cattle production systems. We also derive farmers’ preferences for various DFZ policy scenarios. The findings have important implications for policy on the design of DFZ programmes in Kenya and other countries that face similar cattle disease challenges.  相似文献

Abstract

This study provides new insights on consumer preferences for chicken welfare attributes in a developing country context. Further, the inclusion of chicken transportation methods as an attribute is a useful contribution to empirical literature. Choice experiment survey data from 200 chicken consumers in Kenya were analyzed using random parameter logit model. Consumers had a positive preference for use of certified transportation, humanely slaughtered chicken and welfare labeling. However, there was a negative preference for using antibiotics in chicken production. Relative to the current price of chicken meat, consumers were willing to pay a premium of 30% for use of certified transport, 72% for animal welfare labeling, 135% for humane slaughter, 236% for nonuse of growth hormones and 40% less for chicken reared in confined systems.  相似文献

Income inequality and inflation: the cross-country evidence   总被引:1,自引:0,他引:1  
Different strands of the political economy approach to macroeconomic policy imply a link between income inequality and inflation. This article tests this proposition using a newly assembled data set on income distribution. The results show that income inequality is associated with higher inflation. This association, although not economically large, holds for democracies as well as nondemocracies. Sensitivity analysis suggests that the results are not due to measurement error, reverse causation, or omitted variables.  相似文献

在森林生态系统的养分循环研究中,粗木质残体(CWD)的分解是目前的一个热点课题,CWD研究所包括的范围很广,森林砍伐后伐根分解的研究就是其中一个较新的领域,虽涉及者不多,但伐根在森林生态系统中所具有的生态作用却不容忽视。由于对伐根分解了解的不足,导致对森林生态系统碳储量估算的误差增加,达到了2%~10%,因此应该加快对伐根分解的研究。  相似文献

Advances in information communication technology (ICT) has seen many hotels invest huge sums of money in ICTs to enhance their performance. However, this has never been the case for most hotels in economically developing countries due to poor ICT implementation. This study sought to establish how ICT-related management practices influence actual ICT application by hotels in Kenya. A total of 194 hotel managers drawn from 36 hotels were surveyed. The data collected was analyzed quantitatively. The outcomes show that though operational management and human resource management practices significantly predict actual ICT application, HRM practices have the biggest effect in explaining the variance in actual ICT application. The study finding offer insights to best management practices and how they influence actual ICT use in hotels.  相似文献

Abstract

Actual development of water and wastewater systems in towns is an outcome of several interrelated factors such as physical, economic, and social environments. Demography is also an important factor to consider in the formulation of development strategies. Too often in policy papers, population increase only serves as an argument for urgent action, but rarely as a factor in its own right that affects chances of improving a grave situation. A model is developed to generate water management options in urban areas related to population growth. A hypothesis is that management should go small in periods when the city expands rapidly. A study is presented of the development of water and sanitation in the town of Kisumu in Kenya on the shore of Lake Victoria during last century. The aim is to describe and analyze actual development in the water sector and to foresee what prospective developments could be identified in light of continued rapid population growth. The slow growth of the town in the colonial period allowed towns to adequately meet the needs of all residents for water. The extremely rapid population growth after Independence in 1963 interacted with other factors to cause a successive deterioration of residents access to water and sewage disposal.  相似文献

Lake Kanyaboli, an isolated satellite lake of Lake Victoria, has been suggested as a potential refugium for haplochromine cichlids that have gone extinct in the main basin of Lake Victoria. Mitochondrial DNA (mtDNA) molecular markers, as well as feeding ecology studies, were employed in this study to re‐evaluate the evolutionary and ecological significance of six common Lake Kanyaboli haplochromines. The mtDNA marker revealed high genetic variability within four of the six haplochromine cichlids. Five haplotypes were discerned in Astatoreochromis alluaudi (n = 27), seven in Lipochromis maxillaris (n = 29), five in Astatotilapia nubila (n = 12) and 11 in the endangered Xystichromis phytophagus (n = 205). A haplotype genealogy suggests that Lake Kanyaboli harbours mtDNA haplotypes that could have been lost or not sampled in Lake Victoria, or could have arisen in situ. Lipochromis maxillaris appears to have undergone a recent demographic expansion. The pairwise FSTs indicated that only the comparison between X. phytophagus and A. nubila led to a non‐significant FST value. All other comparisons were significant at the 0.01 level, indicating the genetic distinctiveness of the haplochromines in the satellite lake. This could suggest that the lake harbours ‘pure’ relict populations of the haplochromines and therefore that Lake Kanyaboli can be considered a ‘genetic reservoir’. Gut content analysis of the six haplochromine species revealed that eight different food items were consumed. No single species fed exclusively on a single food item, but certain food items contributed higher proportions of the fish diet for each fish species. Resource partitioning therefore could be discerned within this haplochromine community. Thus, Lake Kanyaboli and similar satellite lakes provide an opportunity for conservation of both genetic and trophic diversity threatened by introduction of exotics in the Lake Victoria basin. Lake Kanyaboli should be recognized and conserved as important evolutionary significant units for Lake Victoria region haplochromine species.  相似文献
