Technology significantly affects human ability to control and adapt to their natural environments and has affected society and its surroundings in several ways. While we cannot totally prevent the consequences of climate change, scientific knowledge and technical know-how can be applied to adapt to its impacts. Climate change impacts have the potential to transform the pattern of crop productivity, livestock and fishery systems, and reconfigure food distribution, markets and access in Nigeria. The primary objective of this paper is to examine the technology management options to address climate change and food security challenges in Nigeria.
Understanding climate change
A. Natural causes
Many studies have ascribed natural, human activities or both as causative factors of climate change. For instance, naturally the climate goes through different cycles of variable duration, alternating between cold and hot periods. The earth has gone through several phases of warming and cooling over the last 700,000 years, at an average frequency of 100,000 years per cycle (Denhez, 2007). The warm period undoubtedly affected the development of agriculture and animal husbandry. Nevertheless, the consensus among many scientists in the last few years ascribed the cause of major global warming to human interference with the climate system.
B. Human causes
It is how widely agreed that the main cause of the present climate change is the emission of green house gases mostly carbon dioxide, methane, nitrous oxide in large quantities by human activities. These activities include agricultural production, industrialisation, burning of fuels and deforestation, wetland degradation, among others (Stern 2007). These gases react with the ozone layer which protects the earth from the sun radiation. Reports showed that agriculture contributes 10percent and deforestation accounts for almost 20percent of green house gas emissions to climate change. These green house gas emissions are sequestrated in oceans, forest … Read More...
