Candidates with a BSc Honours Degree in Environmental Science and Health or Bachelor of Environmental Science Honours Degree in Public Health or any other related field with at least a lower Second class will normally be eligible for admission into the programme.

The Msc in Environmental health programme runs in synchronisation with the Block Release Programmes at NUST. The duration of the programme is twenty-four (24) months. It is offered on Block Release over two (2) Stages. The programme comprises of two blocks in each stage and each block has three (3) weeks of class contact. Teaching and learning continues in the form of assignments in between the blocks. The taught courses offered run for a total of 58 hours class contact each i.e. 29 hrs lecture time, 10 hours tutorials and 19 hours practicals. The project leading to a dissertation runs for twelve (12) months.

Considering the appreciation of linkages between the environment and health, (basing on the statistic that environmental risks contribute 28 per cent of Africa's disease burden), international organisations such as UNEP, intergovernmental panels such as the African Ministerial Conference on the Environment (AMCEN) and local government arms such as the Zimbabwean Ministry of Health and Child Care  are focusing on and placing environment and health issues at the top of their national and continent-wide policies. These policies are aimed at tackling growing challenges such as air pollution and respiratory infections; vector-borne diseases such as diarrhoea; malaria, chemical exposures and other environmental health impacts.

In this regard, this MSc in Environmental Health will contribute to such efforts through advanced knowledge and skills impartation and training, generation of new scientific knowledge in the area of environmental health through research to guide policy development and implementation in areas such as epidemiology, environmental toxicology and Health systems management. The target group for this programme is therefore honours degree in Environmental Science and Health and Public health holders and any other related field who are interested in furthering their studies in environmental health issues for lasting solutions.  This programme is offered on a block release basis to allow working practitioners to participate. Environmental Health is a broad area of study. The programme thus allows students to pursue areas of interest after completing the core courses. The programme focuses on the theory and practice of assessing, correcting, controlling and preventing those factors in the environment that can potentially affect adversely the health of present and future generations.

Expected Outcome
Upon completing the requirements for the Master of Science Degree in Environmental Health, graduates are able to:

  • To evaluate the role that the environment plays in human health
  • Communicate the basic characteristics of major chemical, physical, and biological hazards and the properties that govern the hazards’ behaviour in the environment;
  • Explain the scientific characteristics ( route of exposure, dose response, mode of action) of major biological, chemical, and physical hazards that result in human health risk;
  • successfully apply risk assessment methodologies and management strategies to complex environmental health issues
  • Analyze and interpret environmental health data;
  • Identify appropriate intervention strategies for specific environmental health problems and
  • Communicate the results of a scientific study in a written and oral format.

Candidates with a BSc Honours Degree in Environmental Science and Health or Bachelor of Environmental Science Honours Degree in Public Health or any other related field with at least a lower Second class will normally be eligible for admission into the programme.
