Abstract: Land is a basic, definite and important natural resources which supplies most of man’s food. However, urbanization has remains the major threats challenging the sustainability of agricultural lands in most major growing cities of the developing countries. This research work was carried out to assess the impacts of urbanization on arable land in Makurdi town. The study used Remote Sensing and GIS with satellite images to analysis, mapped and quantified the land use types and extent at which agricultural lands are lost to urbanization within the study period. The findings revealed that the land use types had changed significantly within the study period. The result also shown that, the study area has lost 200km2 of agricultural land representing 19% of the total landmass to urbanization within the study period. Built –up has gained 336km2 representing 32% of the total landmass of the study area within the same period. Thus, the study area has emerged from being predominantly rural area to a city with an appreciable urbanization level. The study recommended that: i. effective and proper management strategies to control urban expansion to agriculture lands by the government are taken such as integrating agricultural land use into urban land use planning. ii. Proactive measure is taken by all stakeholders in the study area towards a better understanding of the changing pattern of land use of the area.Abstract: Land is a basic, definite and important natural resources which supplies most of man’s food.

Abstract: Human Development Index combines three well known dimensions: long healthy life, education and standard of living. Energy influences all these dimensions either directly or indirectly, that is one of the reasons why countries should focus on reducing greenhouse gas emissions that come directly from energy use, and improve energy efficiency activities while at the same time not affecting the human development process. By studying the relationship between energy and human development, through PVAR analysis, this paper contributes to the efforts of promoting renewable energy and energy efficiency while acting globally for climate change mitigation. The analysis covers 4 panels representing four income levels distributed among the globe throughout the period from 1990 to 2015. First and second panel unit root and cointegration tests are being applied after examining for cross sectional correlation between each panel units, then PVAR analysis is being conducted for each panel through a system GMM methodology. Results show that in all of the four panels the impact of renewable energy consumption in reducing the per capita CO2 emissions is found to be insignificant for all of the four panels. Moreover, the impact of the renewable energy consumption on the HDI is found to be insignificant among the selected countries in all of the panels except the lower middle-income countries.Abstract: Human Development Index combines three well known dimensions: long healthy life, education and standard of living.
