Resource Conflict Among Farmers And Fulani Herdsmen: Implications For Resource Sustainability, Olarewaju Oluseyi Ifatimehin, Marietu Tenuche
Olarewaju Oluseyi Ifatimehin
This study describes the traditional relationship between farmers and Fulani herdsmen in the incessant resource conflict witnessed in Kogi State, Nigeria and how it affects livelihood security of those involved and resource sustainability for the communities. These conflicts are most responsible for the unsustainable utilization of land and water resources as the trampling by the hooves of herds of cattle compacts the soil of farm land, destroy farm crops by the herdsmen, places restraint on effective utilization of arable farmland among other destruction of available resources. It is understood that these conflicts have their roots in the land tenure system, …

Urbanization is a process that always initiates the continual transformation of land from one use to the other. Land transformation is presently being experienced in and around fast growing towns, like Anyigba in Kogi State. This study used Remote sensing and GIS techniques to identify, mark, and measure the extent of the various land uses from the Land use map of 1995 and Nigeriasat 1 imagery of 2006. The study revealed that there have been tremendous transformation in the various land uses, with the built-up area expanding more than other land uses with 398.4%. Gaining 167 ha, 613.45 ha, 159.62 …

The Use Of Computer Intelligent Processing Technologies Among Environmental Scientists In Nigerian Universities, Olarewaju Oluseyi Ifatimehin
Olarewaju Oluseyi Ifatimehin
This paper assesses the awareness and usage of a novel approach to data and information processing among scientists, researchers and students in the field of environmental sciences. In depth and structured interview was conducted, targeting a population who are working in a variety of environmental issues. The data generated were analysed using simple descriptive statistics. The results indicate that the level of awareness and responsiveness to this approach is very low (26.5%), and computer proficiency is also very low (30.8%). This suggests the need for a vigorous academic reorientation of all stakeholders through conferences, workshops and seminars.
