"The contemporary world today is paying the prize of industrialization and unwholesome human activities that are manifested in form of climate change. This is all about global warming,and global warming has now been elevated to a global warning. The time to take heed of this warning is now. The paper examined the threats presented by changes in climate all over the world with particular reference to developing countries (Nigeria) where agriculture is a dominant sector and depends on weather and climate. The paper further used the sustainable development model in the form of the Green Wall Sahara Nigeria Programme (GWSNP) as a strategy for greening the drought-prone and desert infested areas of Northern Nigeria (11 States). The paper concludes with the assertion that the challenges of climate change to economic growth and sustainable development in Nigeria require creative thinking, holistic ideas , innovative solutions and the involvement of all stakeholders."
