KARACHI - There are significant factors that are affecting global warming in the region, but it is a cruel fact that global warming will have dangerous repercussions for Pakistan. From affecting the agriculture sector, which is the backbone of the economy, to deforestation in the country. The agricultural ecosystem can collapse due to global warming and associated risks due to rising temperature that can lead to catastrophes like droughts, water shortages, productivity and biodiversity loss across the world. Pakistan is confronted with environmental deterioration in agro-ecosystem and it may cause change in land use due to contamination of farmlands by chemical waste of the factories. Factually speaking, 70 per cent of the total land of Pakistan is located in arid and semi-arid regions, while droughts and loss of biological productivity are a common phenomena in the country. Another factor is the deforestation which is the basic reason for global warming, water scarcity and food shortage in many parts of the world including Pakistan. Pakistan is a water scarce country and requires modern technology capable of holding moisture for a long time for cultivation and forestation. So much for the warm weather forecast, global warming issues and climatic change occurring in our part of the world but no step is being taken in this regard to avoid the harmful effects it generates and can hugely damage the ecosystem at length.
