This has resulted in the degradation of urban environments, overuse of natural resources and widespread pollution of ecosystems, The patterns of design initiatives continue to follow unsustainable path with impacts on stream ecosystems. Accordingly, the paper adopts geospatial information systems and sustainability principles for the identification and sequential mapping of stressors impeding natural systems in Southern Mississippi. The results not only reveal that the study area experienced some significant changes in its watershed environments, but the stream habitat ecosystem remains under stress. The recommendations for mitigating the problems range from policy considerations to the adoption of ecosystem approach.展开更多

Flooding is one of the various ecological problems that has taken its toll on the quality of the environment, human health, and economic growth in parts of Africa and the coastal zones of Nigeria in particular. Rapid urbanization has been seen to result in changes in land use patterns which can adversely affect the hydrological processes in a catchment leading to a deteriorating water environment. warning systems are identified and discussed in the paper Structural and non-structural approach as well as flood early as flood risks coping mechanisms, It also discusses the policy implications that government through its relevant agencies must be up to its game by monitoring precursors, forecasting of probable floods and notification of alerts, It concludes and recommends that an active involvement of communities at risks is required and public education and awareness of risks should be facilitated through effective dissemination, as well as ensuring that there is a constant preparedness,展开更多
