Climate Change and the Impact of Alien Plant Species in an Urban Environment: An Urban Ecological Perspective

Abstract


Intentional or unintentional introduction of exotic plant species with short-term gains created a serious ecological challenges for the fragile ecosystem around the world.  During the last two centuries the invasion of alien species has dominated the urban habitats especially in developing countries. These species are introduced by systematic planning and design apparently with a special purpose (e.g., sand dune stabilization, beatification, rapid green cover, erosion control, waterlogging resistant etc.). However, at few instances, these species just burst-out accidently and implicated into a serious ecological crisis at many places around the world.

Furthermore, the climate change implications most often generated warmer temperatures and changes the level of carbon-dioxide which consequently increases the dispersion of IAS to the border biogeographic regions, especially in emerging mega cities like Karachi. It has been also observed in Karachi that horticultural selection of plant species seriously lacks local ecological perspective, as the indigenous plant species are not on their priority list. This mono-culture of plants affect the aesthetics of the city which was used to be highly resentable before three decades because of the good plant spatial diversity.

In this context this DAAD sponsored project at Humboldt Universität zu Berlin have measured the intensity and invasion of these plant species and has provided the accurate spatial extent of the problem in one of the largest cities of the world through the utilization of temporal satellite data. In addition, it has also identified the high-risk areas of IAS especially at the periphery of traditional agricultural areas.

The opportunity of the spatial assessment of these species will also suggest the eradication and control or of this menace. Similarly, it would recommend the mechanisms to bring these species into the current ecological system in highly valuable manner for their eco-friendly utilization. The outcome of the project will provide an automated GIS tool to the concerned agencies for the effective management of IAS in Pakistan.
