Preliminary studies on the vulnerability of various sectors
of the Nigerian economy to Climate Change were conducted
by NEST. The sectors evaluated were based on seven natural
and human systems identified by the IPCC, and condensed
into five. They are:
• Human settlements and health;
• Water resources, wetlands, and freshwater
• Energy, industry, commerce, and financial
• Agriculture, food security, land degradation,
forestry, and biodiversity; and
• Coastal zone and marine ecosystems.
The study determined that virtually all of the sectors
analyzed manifested some evidence of vulnerability to
climate change. None were unaffected, nor will remain
unaffected in future by changes to climatic conditions.
In fact more recent assessment, although in regional and
global scale, not only corroborate the patterns established
by CN-CCCDP reports but captured more disturbing scenarios
using more embracing and sophisticated approaches (IPCC,
2007). Indications are that the climate system is more
sensitive that originally thought.
