Climate change/variability and hydrological modelling studies in Zimbabwe: a review of progress and knowledge gaps.

This paper reviews developments in climate science and hydrological modelling studies in Zimbabwe over the past 29 years in an effort to expose knowledge gaps within this research domain. We initially give a global and regional overview and then follow a systematic thematic approach in reviewing specifically online published, peer-reviewed journal articles on climate change/variability and hydrological modelling in Zimbabwe. The state and progress towards advanced integrated climate and hydrological modelling research are assessed, tracking benchmarks in the research methodologies (tools and techniques) used therein including geographic information systems and remote sensing. We present descriptive summaries of key findings, highlighting the main study themes (categories) and general conclusions arising from these studies while examining their implications for future climate and hydrological modelling research in Zimbabwe. Challenges associated with climate and hydrological modelling research in Zimbabwe are also briefly discussed and the main knowledge gaps in terms of research scope and methodologies employed in the reviewed studies also exposed. We conclude by presenting plausible potential areas of focus in updating and advancing scientific knowledge to better understand the climate-land use-hydrology nexus in Zimbabwe. While this paper is primarily relevant for researchers, the general findings are also important for policy-makers since it exposes potential areas for policy intervention or agenda setting in as far as climate and hydrology science research is concerned so as to effectively address pertinent questions in this domain in Zimbabwe.

An assessment of risk factors for contracting rabies among dog bite cases recorded in Ward 30, Murewa district, Zimbabwe.

BACKGROUND: Zoonoses are a major threat to human health. Worldwide, rabies is responsible for approximately 59 000 deaths annually. In Zimbabwe, rabies is one of the top 5 priority diseases and it is notifiable. It is estimated that rabies causes 410 human deaths per year in the country. Murewa district recorded 938 dog bite cases and 4suspected rabies deaths between January 2017 and July 2018, overshooting the threshold of zero rabies cases. Of the 938dog bite cases reported in the district, 263 were reported in Ward 30 and these included all the 4suspected rabies deaths reported in the district. This necessitated a study to assess risk factors for contracting rabies in Ward 30, Murewa. METHODOLOGY/ PRINCIPAL FINDINGS: A descriptive cross sectional survey was used for a retrospective analysis of a group of dog bite cases reported at Murewa Hospital, in Ward 30. Purposive sampling was used to select dog bite cases and snowball sampling was used to locate unvaccinated dogs and areas with jackal presence. The dog bite cases and relatives of rabies cases were interviewed using a piloted interviewer-administered questionnaire. Geographical Positioning System (GPS) coordinates of dog bite cases, vaccinated and unvaccinated dogs and jackal presence were collected using handheld GPS device. QGIS software was used to spatially analyse and map them. Dog owners were 10 times more likely to contract rabies compared to non-dog owners (RR = 10, 95% CI 1.06-93.7). Owners of unvaccinated dogs were 5 times more likely to contract rabies compared to owners of vaccinated dogs (RR = 5.01, 95% CI 0.53-47.31). Residents of the high density cluster (area with low cost houses and stand size of 300 square meters and below) were 64 times more likely to contract rabies compared to non-high density cluster residents (RR = 64.87, 95% CI 3.6039-1167.82). Participants who were not knowledgeable were 0.07 times more likely to contract rabies, compared to those who had knowledge about rabies. (RR = 0.07, 95% CI 0.004-1.25). Our study shows that the risk factors for contacting rabies included; low knowledge levels regarding rabies, dog ownership residing in the high density cluster, owning unvaccinated dogs and spatial overlap of jackal presence with unvaccinated dogs.

Factors associated with home births in a selected ward in Mberengwa District, Zimbabwe.

OBJECTIVE: Despite many efforts put by the Government to ensure that women give birth in health facilities under trained personnel supervision; statistics suggest that ward 2 in Mberengwa District in Zimbabwe has the highest home births. This study sought to assess factors that are associated with home births in ward 2 of Mberengwa District in Zimbabwe. DESIGN: Case- control. SETTING: Ward 2 in Mberengwa District in Zimbabwe. PARTICIPANTS: 35 and 105 women who gave birth at home and facilities, respectively. METHODS: A piloted researcher administered questionnaire was used to collect data from systematically selected respondents on factors leading to their choice of place to give birth. The home and facility births were geocoded using a Garmin etrex-30 Global Positioning System receiver and exported to Quantum Geographic Information System software for spatial analysis and mapping. RESULTS: Factors associated with home births were; being uneducated (2.90, CI 1.08-7.57), unemployed (2.56, CI 1.08-6.23), could not afford facility bills (20.92, 3.19-160.31), and lack of access to Ante Natal Care (23.8, 7.04-90). 69% (24) of cases and 30% (32) of resided within the 5 km radius of health facilities. There was significant difference in levels of knowledge between cases and controls about benefits of giving birth in facilities. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: It is acknowledged that costs are a huge barrier in accessing antenatal care services. These factors together with others need to be addressed so as to improve access by pregnant women to health facilities.
