Item Characterising wildlife trade market supply-demand dynamics(Public Library of Science, 2016) McNamara, J.; Rowcliffe, M.; Cowlishaw, G.; Alexander, J.S.; Ntiamoa-Baidu, Y.; Brenya, A.; Milner-Gulland, E.J.The trade in wildlife products can represent an important source of income for poor people, but also threaten wildlife locally, regionally and internationally. Bushmeat provides livelihoods for hunters, traders and sellers, protein to rural and urban consumers, and has depleted the populations of many tropical forest species. Management interventions can be targeted towards the consumers or suppliers of wildlife products. There has been a general assumption in the bushmeat literature that the urban trade is driven by consumer demand with hunters simply fulfilling this demand. Using the urban bushmeat trade in the city of Kumasi, Ghana, as a case study, we use a range of datasets to explore the processes driving the urban bushmeat trade.We characterise the nature of supply and demand by explicitly considering three market attributes: resource condition, hunter behaviour, and consumer behaviour. Our results suggest that bushmeat resources around Kumasi are becoming increasingly depleted and are unable to meet demand, that hunters move in and out of the trade independently of price signals generated by the market, and that, for the Kumasi bushmeat system, consumption levels are driven not by consumer choice but by shortfalls in supply and consequent price responses. Together, these results indicate that supply-side processes dominate the urban bushmeat trade in Kumasi. This suggests that future management interventions should focus on changing hunter behaviour, although complementary interventions targeting consumer demand are also likely to be necessary in the long term. Our approach represents a structured and repeatable method to assessing market dynamics in information-poor systems. The findings serve as a caution against assuming that wildlife markets are demand driven, and highlight the value of characterising market dynamics to informappropriate management.Item A community-based feasibility study of National Health Insurance Scheme in Ghana(African journal of health sciences, 2002-01) Edoh, D.; Brenya, A.In a community based study at Legon in 1997, a valuation method was used to assess the willingness of students on study leave to pay a percentage premium of their income towards a National Health Insurance Scheme (NHIS). Thirty-five percent of the respondents were aged 30-40 years, 97% were males, 45% were resident in Accra, 17% in Kumasi and 12% in Cape Coast. Respondents were 84% in formal public employment with 44% majority as teachers. Their monthly income was distributed as 33% earned below currency 200,000, 50% between currency 200,000-currency 400,000 and 7% above currency 400,000. More than 74% were willing to contribute to the scheme with 38% and 37% willing to pay 1% and 2 of their income as monthly premium respectively. Those willing to pay 2% premium, 14 (n=33) earned below currency 200,000, 18 (n=50) between currency 200,000-currency 400,000, and 5 (n=17) above currency 400,000. Malaria was the commonest disease with 86% incidence, however 30%of respondents revealed they did not spend money on hospital services except 39% who spent currency 20,000-currency 100,000 on hospital laboratory services. Over 65% of respondents indicated they self financed their health expenditure. The premium level was found to be influenced positively by financier, sex, age, income, and negatively by health expenditure, but not occupation. In an elite community with inadequate infrastructure and water supply problems but probably with better personal hygiene and sanitation, although respondents hardly spend on health services they were willing to contribute 2% of their incomes as premium towards an insurance scheme.
