Degree Type:Master of Philosophy
Department:Department of Soil Science
2 years (Standard Entry)
Modes of Study:Regular
Since the inception of the postgraduate programme in 2001 in ‘pure’ Soil Science, the department has found it increasingly difficult to attract students, which perhaps could be partly due to the low demand for ‘pure’ Soil Scientist in the job market. This problem, coupled with the threat to the health and well-being of people and global systems posed by environmental degradation and climate change, prompted the department to review its postgraduate programme. The review indicated the need to design a programme which will train graduates to tackle problems of environmental degradation in a sound way.
MPhil. programme: Candidates with BSc. Degree with Second Class (Lower Division) and above from a recognized University in Biological Science, Soil Science, Agriculture, Agricultural Engineering, Environmental Science, Renewable Natural Resources and other related Earth Sciences.
Goal / Objectives:
(i) To expose students to the scientific principles of pollution at chemical levels and soil management in order to enable them approach environmental issues in a realistic way.
(ii) To equip students with the concepts and procedures of land evaluation and use soil/land data to substantiate suitability of soil/land for specific purposes.
Employment Prospects of Graduates:
List of sectors of the economy that could employ graduates of the programme include:
(1) Soil Research Institute
(2) Ministry of Food and Agriculture
(4) Crop Research Institute
(5) Environmental Protection Agency
(6) Multilateral organizations and Banks
