The analysis of this map show also that the urban structure types play really a key role in addition to population density, flat slope and heavy rainfall into the risk of flooding in Abidjan; as well as other anthropogenic factors (uncontrolled urbanization) showing morphology level play an aggravating role in the risk of flooding.
On the contrary, the presence of the river crab, within its occurrence zone, was not associated to any biotic and abiotic parameters and was probably affected by anthropogenic pressure and uncontrolled harvesting.
Incidental nanoparticles (natural and anthropogenic) are generated in a relatively uncontrolled manner and are usually physically and chemically heterogeneous compared with engineered nanoparticles (NIOSH 2006).
Indiscriminate and uncontrolled discharge of hazardous heavy metals into the environment by means of anthropogenic as well as geogenic activities leads to the contamination of water, soil, and air.
It may be due to some other anthropogenic activities such as intrusion from domestic sewage or possibly due to uncontrolled agricultural practices.
Current planning policies implemented by the state suggests that proper attention is given to mitigation of anthropogenic activity, however the dynamics of the urban sprawl continue to be uncontrolled and sporadic.
Unfortunately, the natural habitat and effective population size of many freshwater fishes such as T. tambroides which require clean running water with gravels and rocks are rapidly being degraded due to anthropogenic disturbances (i.e., river pollution, deforestation, watershed erosion, and others) and uncontrolled fish harvesting [ 4].
Abidjan is the economic capital of Cote d'Ivoire and known for its perpetual population growth characterized by continuous uncontrolled urbanization due to demographic growth which creates gap in the context of climate change and anthropogenic impact related to safe environment and healthy life (Fig. 5).
Contaminants in surface and groundwater may come from anthropogenic sources, runoff from agricultural activities (Chapin et al. 2005), or controlled or uncontrolled discharges from sewage treatment facilities or leaking landfill sites (Kolpin et al. 2002).
