Engineering College holds Monthly Seminar

Debre Berhan University Engineering College Mechanical Engineering Department held its 3rd monthly seminar on January 16, 2020 at Mechanical Engineering Computer Laboratory, LA05.

On the seminar, Abebe Tadesse /PhD/, Director for International Relation and Partnership, presented paper entitled on “Moveable Farm: Aquaponics a nexus of Re-circulating Aquaculture and Hydroponics.”

He summarized his presentation as: Feeding the world population by conventional agriculture is going to be difficult due to loss of soil productivity, climatic change, and limited amount of resources and also dwindling of fresh water amount. These problems lead the world to search for an alternative new, healthy, environmental and user friendly food production technology. This can be assured by integrating biologically the existing food production technologies aquaculture and hydroponics, by minimizing resource utilization and removing the waste excreted to the environment. The combination of these technologies is termed as Aquponics. Aquaponics is an organic food production system which serves as a model of sustainable food by different principles. The principles which make Aquaponics sustainable are combination of the system, product diversity, and efficient resource utilization, enable food access, and enhance the local economy. The system can be operated at a backyard level for a household consumption at a community farm level especially in areas with land shortage (urban) or commercial level.

The participants raised questions about the mass production and the level technology which can be applied at small scale and the drawbacks faced on controlling the airing and producing oxygen for aquatic animals like fish and plants. They also asked questions whether we apply the technology at household level or in a large scale as it consumes money.

Abebe Tadese/PhD/ verified the drawbacks and the airing system. It is possible to farm it as a household level and the produce is very attractive and yields much in a small farm. He called the Engineering experts to participate in designing the model and improve the existing models.
