“…This concept forms the basis of the global framework for the progressive control of FMD that is described in the accompanying paper (Rweyemamu et al., 2008). The concept of regional epidemiological clustering as a basis for developing global strategies for FMD control, which were previously described by Rweyemamu and Astudillo (2002) has been more extensively elaborated in the present paper.…”

Foot-and-Mouth Disease (FMD) is a clinical syndrome in animals due to FMD virus that exists in seven serotypes, whereby recovery from one sero-type does not confer immunity against the other six. So when considering intervention strategies in endemic settings, it is important to take account of the characteristics of the different serotypes in different ecological systems. FMD serotypes are not uniformly distributed in the regions of the world where the disease still occurs. For example, the cumulative incidence of FMD serotypes show that six of the seven serotypes of FMD (O, A, C, SAT-1, SAT-2, SAT-3) have occurred in Africa, while Asia contends with four sero-types (O, A, C, Asia-1), and South America with only three (O, A, C). Periodically there have been incursions of Types SAT-1 and SAT-2 from Africa into the Middle East. This paper describes the global dynamics for the seven sero-types and attempts to define FMD epidemiological clusters in the different regions of the world. These have been described on a continent by continent basis. The review has reaffirmed that the movement of infected animals is the most important factor in the spread of FMD within the endemically infected regions. It also shows that the eco-system based approach for defining the epidemiological patterns of FMD in endemic, which was originally described in South America, can apply readily to other parts of the world. It is proposed that any coordinated regional or global strategy for FMD control should be based on a sound epidemiological assessment of the incidence and distribution of FMD, identifying risk sources as either primary or secondary endemic eco-systems.

“…The seven serotypes of FMD virus produce a disease that is clinically indistinguishable but immunologically distinct (OIE 2004). It is endemic with high prevalence in Africa, the Middle East, and Asia and is also present in parts of South America while industrialized countries are free from the disease (Rweyemamu and Astudillo 2002). However, it is a global problem since the result of increasing movement of human and livestock and livestock products (Perry and Rich 2007).…”

Cross-sectional serological study and questionnaire survey were conducted in Borana pastoral and agro-pastoral area to determine seroprevalence and risk factors associated with foot-and-mouth disease (FMD) infection and to assess community perceptions as to importance of the disease. A multistage random sampling was carried out to select cattle for seroprevalence and households for interviews. Totally, 768 sera were collected from 111 herds. The overall individual level seroprevalence of 23.0% (n = 177) and herd level seroprevalence of 58.6% (n = 65) were recorded using 3ABC ELISA test. The variation of individual level seroprevalence in districts were statistically significant (P < 0.05) which was 29.9% in Arero, 24.0% in Yabello, and 15.7% in Teltele. From multivariate logistic regression analysis, herd size and age were seen to be significantly (P < 0.05) associated with FMD seroprevalence. The result of the questionnaire survey based on 120 respondents indicated that, the daily milk yield of cows infected with FMD during outbreaks is reduced to an average of 0.5 L for 25.5 days while cows developing heat-intolerance syndrome after acute infection gave an average 0.67 L for 3.8 months and their calving interval prolonged about 12 months. The questionnaire survey in agro-pastoral area of Borena also indicated that FMD-infected oxen remained off-plough for one season when outbreaks occur in cropping time, whereas heat-intolerant oxen were no longer used for traction. These findings of the present study indicated that FMD is a highly prevalent and economically important disease in the Borana pastoral and agro-pastoral production systems which need effective control strategy for the disease.

“…Moreover, just as the closer integration of world markets for foods, fuels, and fibers has increased the dispersion rate of agricultural pests and pathogens (McNeely, 2001;Rweyemamu and Astudillo, 2002;Karesh et al, 2005;Fevre et al, 2006), so the development of tourism and the closer integration of world markets for many services has increased the dispersion rate of human pathogens (Tatem et al, 2006;Smith, 2008). Not all species contribute positively to human well being.…”

This paper assesses how the economics of biodiversity, as a field, has evolved in response to developments in biodiversity science and policy over the life of the journal, Environment and Development Economics. Several main trends in the economics of biodiversity are identified. First, biodiversity change has come to be analyzed largely through its impact on ecosystem services (in the sense of the Millennium Ecosystem Assessment). Second, there has been a growing focus on factors that optimally lead to biodiversity decline, i.e., the benefits to be had from reducing the abundance of pests, predators, pathogens, and competitors. Third, increasing attention is being paid to two global drivers of biodiversity change, climate and global economic integration, and the effect they have on the distribution and abundance of both beneficial and harmful species. Fourth, there has been growing interest in the development of instruments to deal with the transboundary public good aspect of biodiversity, and in particular in the development of payments for ecosystem services. The paper identifies the influence of these trends on attempts to model the role of biodiversity in the production of goods and services.
