Academic and environmental expert Prof. Haruna Ayuba has proposed evaporation suppression as alternative technique to save Lake Chad from extinction.
Ayuba, who teaches at the Nasarawa State University, Keffi (NSUK), spoke in an interview with News Agency of Nigeria (NAN) in Abuja.
He said water transfer was the first option in restoring the lake, adding that this will require the movement of water from another river.
‘‘Suppressing evaporation can also help in the restoration of Lake Chad. We live in the tropics and we receive much water from rainfall.
‘‘The water disappears through evaporation; we can suppress the evaporation which is the amount of moisture that goes up into the atmosphere.
‘‘Part of the reasons for the drying up of Lake Chad is the high rate of evaporation of water,” he opined.
The don said stakeholders should create more awareness on measures to save the lake.
‘‘Climate change is a developmental issue, every hand must be on deck.
‘‘We need to build capacity, tell people the signs of climate change, because some people don’t understand that.
‘‘We need all the experts, stakeholders to develop a policy framework that people need to follow,” he said.
Similarly, he said with proper use of science and technology, scientists can reduce challenges of restoring the shrinking lake.
According to him, development of science and technology in Nigeria is still laid-back, adding that the country lacks a strategic plan to build the sector.
He decried the lack of equipment for science-related courses in tertiary institutions.
Ayuba noted that polytechnics, which were established to drive the sector, have been allegedly disregarded.
‘‘We have also killed our polytechnics; the polytechnics are supposed to help in building the technical manpower in the country.
‘‘Now, the emphasis is on paper qualification, even those who graduate from polytechnics are coming to take degrees all over again,” he said.
He said the nation should emphasise practical application of acquired knowledge and discourage paper qualification.
NAN reports that Lake Chad Basin has shrunk to 2,500 square kilometres in 2000 from its 1960s’ size of 25,000.
