Agricultural and Environmental Engineering

The Department of Agricultural and Environmental Engineering started in the 1970s as the Department of Agricultural Engineering in the Faculty of Agriculture of the then College of Science and Technology, Port Harcourt, which continued up to the 1980s when the College became Rivers State University of Science and Technology. In 1990, the Department of Agricultural Engineering demerged from the Faculty of Agriculture and merged with the Faculty of Engineering, where it is currently domiciled.

Following the recommendation of the Council for the Regulation of Engineering in Nigeria (COREN) Accreditation Team in 2002, the Senate of the then Rivers State University of Science and Technology approved the addition of the Environmental Engineering option to the academic curriculum of the Department of Agricultural Engineering and the change of name to Department of Agricultural and Environmental Engineering in 2003. In 2004, the Department received full accreditation from COREN and the National Universities Commission (NUC), which it has consistently retained until date.

In 2021, the NUC introduced the Core Curriculum and Minimum Academic Standards (CCMAS) for Nigerian University System in Engineering and Technology to replace the BMAS in the 2023/2024 academic session. In the CCMAS, two distinct programmes were prescribed, among others. They are B.Eng Agricultural and Biosystems Engineering and B.Eng Environmental Engineering. Consequently, like every other university in the country, a new academic curriculum that conforms with CCMAS was approved by the Senate of the University, which allows the Department to run programme leading to the award of B.Eng Agricultural and Biosystems Engineering. However, the curriculum for the award of B.Eng Environmental Engineering, in compliance with CCMAS, is currently being reviewed by the Senate Curriculum and Instructions (C&I) Committee.

With the commencement of B.Eng Agricultural and Biosystems Engineering programme in 2023/2024 Academic Session, the B.Tech Agricultural and Environmental Engineering programme now has students from 300 level to 500 level. Consequently, the synopsis of each of the courses in the programme curriculum of the B.Tech Agricultural and Environmental Engineering has been upgraded to comply with the COREN’s requirements for Outcome-Based Engineering Education (OBEE) such as Programme Educational Objectives, Programme Outcomes, Course Learning Outcomes, Continuous Quality Improvement and Quality Management Concept, involvement of the stakeholders such as academic staff, student, industry player, alumni and university authority in the education process.

The Department has qualified resident and visiting academics in all the areas of specialization as well as emerging areas such as Biosystems and Precision Agriculture. It has a Farm Workshop equipped to handle tractor repair and maintenance education, cutting, fitting, milling, and welding operations. The Department also has well-equipped soil and water/ environmental engineering, post-harvest processing and storage, and farm power and machinery laboratories. Additionally, students of the Department have direct access to laboratories at the Faculty of Science, Institute of Pollution Studies, and laboratories of other engineering departments. Students of the Department also get excellent support from enthusiastic academics and committed technical and secretarial staff. The Department focuses on professional practical elements of study and development of transferable skills, which our students need to function effectively in the industries. The multidisciplinary nature of the Department also increases the opportunities for social mobility of our graduates, which makes the Department unique. The Department joins the Management of the University to wish you the best as you join us on the journey of progress and success.

DUTIES AND RESPONSIBILITIES OF THE DEPARTMENT

The Department has two Boards that are responsible for the decision making process in matters that strictly concern the Department. These Boards are:    (i) The Departmental Board; and   (ii) The Board of Examiners. The Departmental Board, which is made up of all senior staff of the Department, including senior non-academic staff, deliberates on issues of general interests to the Department. The Departmental Board of Examiners is made up of only academic staff and it considers academic matters as it affects the students. To facilitate the activities of these Boards, members of staff are allocated specific duties as well. Examples of these include having staff in-charge of issues like Examination, Postgraduate matters, Calendar and Timetable, Research and Publications, and Students Industrial Work Experience Scheme (SIWES). The Department involves in teaching and supervising students’ projects, theses and dissertation for the undergraduate and postgraduate students. The Department gives professional advice about their careers challenges and is fully engaged the administration of the unit.

STRUCTURE OF THE DEPARTMENT

The Agricultural and Environmental Engineering Department, Rivers State University, Port Harcourt is one of the seven Departments that makes up the Faculty of Engineering. Consequently, the Head of Department is responsible directly to the Dean of Faculty for the day-to-day running of the Department

ACHIEVEMENTS OF THE DEPARTMENT

The Department has a Farm Workshop equipped to handle tractor repair and maintenance, cutting, fitting, milling, and welding operations. In addition to these, students of the Department have direct access to equipment and facilities at the Faculty of Science, Institute of Pollution Studies, Civil Engineering laboratories and Mechanical Engineering in the University. The Department had ran her programs for many academic sessions without its own Laboratories since the inception of the programmes. In 2017 during Council for the Regulation of Engineering in Nigeria (COREN) accreditation, the University donated Charkin building for the Departmental Laboratories. The Department of Agricultural and Environmental Engineering is currently using a temporary space at this Charkin building in the University premises. While this is sufficient for a start, due to lack of Departmental laboratories since the inception of the programmes. This Department of Agricultural and Environmental Engineering Laboratories consist of Farm Power and Machinery Engineering/Farm Structure and Environmental Control Engineering Laboratories, Soil and Water Conservation Engineering/Environmental Engineering Laboratories. These Laboratories to some extents were not equipped. Students of the Department are also given considerable support by enthusiastic academics and committed technical and secretarial staff. The Department focuses on professional, practical elements of study and development of transferable skills, which our students need to function effectively especially in the industries. The multidisciplinary nature of the Department also increases the opportunities for social mobility of graduates. This makes the Department quite unique.

 

        The Department is structured to be the breeding ground of innovation. In fact   some of the final year students of the Department have produced products that have solved economic problems in the society. In 2017 a final year student under the supervision of lecturer in the Department produced a Kitchen- Size Garri Storage Unit. The garri stored in it since 2017 has been preserved for four (4) years without spoiled. This machine is to be available in Nigerian market for commercial purposes. In 2018/2019 academic session, Weeding Machine, Multi-purpose Juice extractor, Fish Feed Dryer and Lawn Mowing Machine were produced by final years students under the supervision our lecturers in the Department.  It is worth commending that in 2019 during NUC preparation for accreditation the university equipped the laboratories to a considerable level. This is a commendable achievement and breakthrough in the Department of Agricultural and Environmental Engineering.

                In 2020/2021 academic session, Agricultural Soil Cone Penetrometer, a Low-velocity Bench-Top Laboratory Fume Hood with a motorized sash, Laboratory Scale of a Municipal Solid Waste Dryer and an Electronic Precision Soil Auger were produced by final year students under the supervision of the lecturers in the Department.

                In 2021/2022 academic session, there has been a considerable reduction in Students complaint on result related issues. The Department of Agricultural and Environmental Engineering has established a Departmental Welfare Committee to care and foster mutual relationship among the staff of the Department.

 There was a renovation work at the Departmental Workshop due to the frequent cases of theft and    burglary incidences which occurred at our Workshop. It will be recalled that ever since this renovation was done, burglary cases had been to a halt.

  The Department of Agricultural and Environmental Engineering had full accreditation of the Department   during the last NUC Accreditation exercise.

PROSPECTS OF THE DEPARTMENT

There are prospects for the department through the Workshop in a number of areas as follows, if the necessary provisions are made:

 

1. Training of Tractor Drivers– The Workshop has one of the most capable tractor operators in Rivers State who was trained during the School-To-Land Programme era of the Rivers State Government. With at least two (2) tractors and two (2) other tractor operators to be recruited, the department can institutionalize Consultancy in Training of Tractor Drivers.

 

2. Tractor and Automobile Maintenance– The Workshop has a service pit, the only one in the whole university. There are auto-mechanic tool boxes and other accessories. Again, the only mechanic is very skilled in both tractors and automobile maintenance. If four (4) other mechanics (two diesel and two auto-mobile) are employed, the department through the workshop can in addition to teaching and research, run consultancy services in this area – that is, maintenance and repairs.

 

  3.Tractor Services – Given the right provisions, that is, dependable new tractors, at least three – one for departmental uses and two for external purposes, the department can run tractor consultancy or hiring services such as maintenance of lawns, slashing of oil pipeline surroundings, land preparation (tillage operations), soil remediation services, and so on. It is noteworthy that the department, through the Workshop had rendered these services in the past when there were good tractors and implements.

 

  1. Fabrication of Small Farm Machines– In times past, when the Workshop had welders, machinists and correspondingly good machines, the Workshop was a mini-fabrication hub. Lecturers and students with designs of machines that needed fabrication did so conveniently in the Workshop. Deterioration had set in with time; but this can be reversed if the required attention in terms of equipment and personnel is given. Small farm machines can be fabricated at the Workshop with proper funding.

 

5.    Support Services for the University Farm– In times past, the Workshop had artisans of various kinds including carpenters, electricians, plumbers, welders, machinists, and so on. So, the Workshop used to perform support services for the Farm such as land preparation, maintenance of the feed mill, maintenance of electrical installations, plumbing works and maintenance, and so on. The Workshop can re-enact this feat if the appropriate personnel, equipment and funding needs are provided.
