Who is to Blame for the Hazardous (Flood Risky) Environment on the Vicinity of Our City Structures?

In the first place, responding to such type of an ambiguous question needs a thorough rethinking, but to me I think it should be imposed directly to either politicians or the planners. Whilst, asking who are the planners? 

These are professionals who work in the field of urban and city planning or land use planning for the purpose of optimizing the effectiveness of a community's land uses and service infrastructure. As such, the planning role is in response to the question and ambitions of our political leaders as the decision making body, depending according to their primary goal or vision of change for the natural and built-up environment. 

So, in accordance to the planning standards, planners normally formulate plans for the development and management of urban and suburban (peri-urban) areas, typically by analyzing land use compatibility as well as economic, environmental and social...trends and on how they interact with each other. In developing their plan(s) for a community (whether commercial, residential, agricultural, industrial or recreational etc), they principally consider a wide array of issues such as sustainability, pollution, traffic congestion, hazard or risky environment, crime issues, land values, legislation and zoning codes. 

For instance, the 1979 Dar es Salaam Master Plan, for more than 3 decades has ever since proposed for the city to have a maximum population size of 2.5 million people. As such, this proposal was provided depending according to the carriage capacity of the valuable city land (except for the hazard areas). Now the city population is claimed to have reached 4 million plus (almost double). Therefore, with effect to such tremendous pressure with an increased population, it has detrimentally surpassed the carriage capacity of the land available plus the service infrastructure. So, for the case of Dar es Salaam; who is to blame for the flood risky, prolonged traffic congestion, chronic pollution and the associated risky environments?

For what I know about the planners, their importance has ever being increasing throughout the 21st century, as the world begin to face issues of increased population growth, climate change, environmental disasters and unsustainable socio-economic developments. They could be considered as green collar professionals. As versatile as they are, they are poised to fit into all sectors of the economy and yet connected and bound in unity and common goals and objectives. Who are these men and women of substance whose values, versatility and authenticity cannot be under-estimated? THESE ARE THE PLANNERS!!!

Besides, toward this end, I positively support the peoples’ noble idea that something ethical has to be done in favour of the endangered families and relatives of our neighbouring communities, where they have massively experienced the catastrophic flood risky. This is especially by assisting them with moral support and physical materials i.e. temporal provision of dwelling for safety and security, medicare, food supplies, clothing as well as clean and safe drinking water and any other livelihood incentives. Although, I consequently stand to say that, living in the hazard land should totally be forbidden for whatsoever reason, where any type of development in the hazard land is not allowed as per principles of the town and country planning ordinance for the continuous sustainability of our livelihood communities.
