The 2012 flood displaced tens of thousands of people and affected over half of the thirty six states destroying properties running into billions of naira. Farmlands and fertilizers were destroyed, settlements were totally submerged and cultural artifacts were lost. The flood was the result of many underlying factors of which the main ones were the release of water from the Lagdo Dam a reservoir located in Cameroon, and the persistent rain fall due to a changing global climate. In response to the flood, a UN-CHARTER was invoked and satellite images were provided by various international space agencies. Likewise organizations such as the World Bank, and various UN agencies together with national stakeholders collaborated in the post disaster recovery efforts. The use of space technology during the response proved to be of great economic benefit particularly in the assessment of the extent of the disaster which assisted the government in its reconstruction efforts. Also the foray of Nigeria into space technologies has opened up its economy in diverse ways especially in the areas of local and international collaborations, employment creation and technological spinoffs. I.INTRODUCTION One of the developments associated with the 21st geographical boundaries, race, and economies. For century that has enhanced the process of example, Hurricane Katrina affected one of the collaboration across diverse geographical world’s richest countries and the Haitian boundaries, is globalization. According to Kouman1 earthquake affected one of the least developed Globalization and collaboration simultaneously countries in the world. Nigeria, a developing nation drive each other and the better, faster and smoother was also not spared as it experienced flooding the collaboration processes and tools are, the more especially in the year 2012 on a monumental scale empowered industries and organizations become in affecting many parts of the country. a global economy. The pace at which technological infrastructure is evolving and being embraced even The frequent occurrence of natural disasters in the st by some developing nations especially in the area 21 century has helped to improve and enhance the of satellite technology has quickened and enhanced technology associated with earth monitoring and the process of collaboration among nations. A Earth Observation Satellites have been the forceful factor that has necessitated collaboration beneficiaries. Thus disasters are now being amongst nations is natural disaster as it transcends IAC-13, B1.5, 10x16566 Page 1 of 8 monitored in real time with correspondents having III.
