Review on Climate change impact on soils: adaptation and Mitigation (Published)

According to the Intergovernmental Panel on Climate Change, global temperatures are expected to increase 1.1 to 6.4°C during the 21st century, and precipitation patterns will be altered by climate change. Soils  are  intricately  linked  to  the  atmospheric–climate  system  through  the  carbon,  nitrogen,  and  hydrologic cycles.  Altered climate will, therefore, have an effect on soil processes and properties, and at the same time, the soils themselves will have an effect on climate. Study of the effects of climate change  on soil processes and properties  is  still  nascent,  but  has  revealed  that  climate  change  will  impact  soil  organic  matter  dynamics, including  soil  organisms  and  the  multiple  soil  properties  that  are  tied  to  organic  matter,  soil  water,  and  soil erosion.  The  exact  direction  and  magnitude  of  those  impacts  will  be  dependent  on  the  amount  of  change  in atmospheric gases, temperature, and precipitation amounts and patterns. Recent studies give reason to believe at least some soils may become net sources of atmospheric carbon as temperatures rise and that this is particularly true of high latitude regions with currently permanently frozen soils. Soil erosion by both wind and water is also likely to increase. However, there are still many things we need to know more about. How climate change will affect the nitrogen cycle and, in turn, how the nitrogen cycle will affect carbon sequestration in soils is a major research need, as is a better understanding of soil water–CO2 level–temperature relationships. Knowledge of the response of plants to elevated atmospheric CO2 given limitations in nutrients like nitrogen and phosphorus and associated  effects  on  soil  organic  matter  dynamics  is  a  critical  need.  There  is  also  a  great  need  for  a  better understanding  of  how  soil  organisms  will  respond  to  climate  change  because  those  organisms  are  incredibly important in a number of soil processes, including the carbon and nitrogen cycles.

REVIEW OF CLIMATE CHANGE AND ITS EFFECT ON NIGERIA ECOSYSTEM (Published)

This paper examines the issue of climate change and its impact on the environment. The effects of man’s activities as well as those of natural phenomena on global warming, climate change and the environment are presented and discussed. The options that are available as response to global warming: mitigation, adaptation and possible human suffering as consequences of what cannot be avoided by mitigation and adaptation are presented. An overview of the Nigerian environment, preparedness for the impact of global warming and related problems are also presented. The status of environmental data and the need for environmental baseline survey and the creation of a comprehensive database for the country driven by geographical information system are presented and discussed. The paper then underscores the need for governments at all levels to adequately fund geo information production and cultivate the culture of its usage for adequate and proactive response to global warming, sustainable environmental management and national development.
