oa Civil Engineering = Siviele Ingenieurswese - Climate change engineering : opinion
There is a dire need for topographic modification : the present river systems will not be able to absorb the increased precipitation safely, as we saw in the Limpopo and Zambezi Rivers in 2000. Obviously, major retention options will be needed to prevent such disasters from happening again. Terracing and reforestation of hillsides as done in Cape Verde are rare here. South Africa needs to recharge its groundwater considerably; it needs to protect its soil from parching and wind erosion. Environmental engineering is of critical importance, but the government is not willing to maintain the academic positions, established earlier with private donations, to provide such knowledge, in spite of the spectacular recent inflow of students to that field of specialisation.
