ABSTRACT
The paper analyzes tropical forest landscape change and deforestation trends in Nigeria. Emphasis’ are on the issues, the environmental analysis of the trends, factors influencing it, and community agroforestry efforts. The time frame and setting for the study runs through the west African nation of Nigeria during the periods of 1976 through 2005 at the national and state levels. In fact, Nigeria was once covered by widespread vegetation comprising of humid tropical forests in the south and savannah grasslands in the north rich in biodiversity. A great percentage of this luxurious vegetation has been cleared by the pressures mounted by human activities with eventual degradation. In terms of methods, the paper uses mixscale approach based on descriptive statistics, temporal spatial analysis and mapping, and photographic images to analyze the trends associated with tropical deforestation. The results show visible changes in the form of large scale decline of Nigeria’s forest landscape over the years. This resulted in the disappearance of forest resources and vegetation cover with mounting threats to sensitive natural areas. Aside from the socio-economic elements linked with the problem, community efforts at the margin using agroforestry systems showed some promise with many benefits to stem the tide of deforestation. To remedy the problems, the paper offered some recommendations ranging from policy overhaul to education.
ABSTRACT
The study uses primary data, descriptive statistics, Geographic Information Systems (GIS) and correlation analysis to analyze the contributions of farming activities to climate change in Mississippi between 1992 through 2002. This involved the assessment of methane emissions from rice cultivation in the state of Mississippi as well as the relationship between the levels of methane gas concentration and other variables associated with rice production. In highlighting the extent to which rice production activities fuel climate change, the results of the study not only showed greenhouse gas emission related rice production activities to be on the rise, but there is a relationship between methane emissions and rice farming. The GIS analysis also points to a visible concentration of rice production activities associated with methane emissions in the major counties of Bolivia, Sunflower and Washington along the Northwest portion of the state. While this raises the threats of climate change predictors in the area. To remedy the problems, the paper suggests five future lines of actions from the need for education to the promotion of emission trading.
