“…In common with previous studies, we found that in the absence of longitudinal data on vector populations and linked ecological drivers, community surveys can be valuable as an indicator (26). Ticks were significantly more likely to be reported as an increasing problem by residents living on islands with a high LD incidence, consistent with this being an emerging issue.…”

“…Tick populations in treeless habitats will be subject to many of the same environmental drivers as those in forested areas, including changes in climate, land management and host density, particularly deer populations (22)(23)(24)(25). Surveys of local communities can provide information on whether the tick hazard is perceived to have changed over time, and suggest possible environmental factors associated with this change which can focus future research (26).…”

Lyme disease (LD) is typically associated with forested habitats but has recently emerged on treeless islands in the Western Isles of Scotland. This has created a need to understand the environmental and human components of LD risk in open habitats. This study quantified both elements of LD risk and compared these between treeless islands with high and low LD incidence. We found high LD incidence was linked to higher prevalence in ticks (6.4% vs 0.4%) and increased human tick bite exposure. Most reported tick bites (72.7%) were within 1km of the home address and commonly in gardens. Residents on islands with high LD incidence reported increasing problems with ticks and suggested changing deer distribution as a potential driver. This study highlights the benefits to public health of an integrated approach to understand the factors contributing to LD emergence and a need to evaluate LD ecology in treeless habitats more broadly.

“…This study used participatory epidemiological (PE) tools to prioritize diseases that affect cattle herds in Mara ecosystem. PE tools have been widely used by researchers to investigate animal health related topics in resource poor areas (Kimaro et al 2017 ; Abdilatif et al 2018 ). In this study, our results showed that livestock production contributes significantly to the livelihoods of the Maasai, consistent with other findings (Bellet et al 2012 ; Ayele et al 2016 ).…”

Livestock-wildlife interactions promote the transmission of a wide range of infectious diseases that constraint livestock production. We used a participatory appraisal approach to find out and rank infectious diseases of concern to pastoralists in a zone of intense wildlife-livestock interaction and another zone with limited interactions. Four villages were selected purposively in areas with intensive cattle-wildlife interactions (zone 1), and another two in areas with low to moderate cattle-wildlife interactions (zone 2). Data were collected in focus group discussions (FGDs) using participatory epidemiological methods (PE); each group had 8–13 participants. Results of impact matrix scoring from all sites indicated that malignant catarrhal fever (MCF), anthrax, foot and mouth disease (FMD), contagious bovine pleuropneumonia (CBPP), east coast fever (ECF) and African animal trypanosomiasis (ATT), in decreasing order, had the highest impact on livestock production. A Kruskal–Wallis test revealed a significant difference in FMD annual prevalence between cattle age groups ( p < 0.001) and was the highest in animals > 4 years (median score of 32.5, range, 10–50). FMD had the highest impact on milk production, but based on veterinary costs (treatment costs), it was ranked second to CBPP. The study provides information on disease priorities that occur in the target zones in Mara ecosystem and which the local pastoralists must consider when accessing key ecosystem services such as water and pasture.

“…The sampling strategy and findings have been described in detail elsewhere (Kimaro et al 2017a(Kimaro et al , 2017b. Briefly, in order to meet the objectives and sample size requirements for the study, a questionnaire was administered to 130 pastoralists across the 10 randomly selected villages between March and May 2015.…”

This study examines pastoralists' perception on climate change and impacts on cattle production from ten study villages of Monduli District in Tanzania. This study drew empirical data from 130 cattle owners and 81 participants from focus group discussions in the study villages. Descriptive statistics and thematic analysis were used to analyze the data respectively. Findings from this study indicate that pastoralists are well aware of the general climate trends in their location, its variability and the impacts of extreme weather events on cattle production. The main climate changes perceived by pastoralists include more erratic and reduced amounts of rainfall, rise in temperature and prolonged and frequent periods of drought. Pastoralists mainly view population pressure and tree cutting as the major causes of climate change. Further, this study found that there are no existing climate risk programmes and early warning systems across the district. Importantly, pastoralists reported the negative impacts of climate change on cattle production. The severe recurrent drought periods result in shortage of forage and water, leading to cattle starvation and malnutrition. Pastoralists reported massive cattle deaths and outbreaks of diseases such as contagious bovine pleuropneumonia and tick-borne diseases. Further, reduction in milk production and poor livestock market prices were also reported as negative impacts on cattle production. Given the range of negative impacts of current climate change and extreme weather events on cattle production, the implications of climate change must be taken into account to ensure longer-term survival and sustainability of pastoralist communities through strengthening of climate risk awareness programs and early warning systems across the district. Further, this study recommends that government and non-governmental organizations should improve institutional support to pastoralists in order to help them deal with the negative impacts of climate change on livestock production.
