Urban population is rapidly increasing at the rate of 1.83% worldwide. This is accompanied by rise in auto-mobile ownership, which conversely imposes adverse environmental, health, economic and social impact in cities. Green Mobility has emerged as the best approach for promoting sustainable and environmental-friendly transportation in modern cities. This paper relied on secondary data to critically review current transport problems, efforts toward ensuring sustainable green mobility, success of the policies and challenges facing the process in Asian cities. The study found that urban transport problems are becoming worst in the cities. However, efforts are in place to reduce car footprint and promote green mobility in the cities. The global overall average score of cities is estimated at 43.9%, while Asia-Pacific cities have 42.8% average score of green mobility performance. The challenges militating against growth of green mobility in cities include fragmented management, lack of clear vision and strategy for the system, and inadequate infrastructure among others. Integrated and coordinated approach is one of the recommendations made towards ensuring sustainable green mobility in cities.

Urban sprawl is a global phenomenon in the contemporary era. It is mostly taking place in the less developed countries due to natural increase and consistent movement of people into the mega cities and large urban centers. The phenomenon has globally gained attention from diverse researchers in the field of urban geography, environmental studies, city and region planning in view of its significant influence on the urban environment. However, the effect of sprawl on urban livability and economy in Nigerian cities is scarcely investigated especially in Northern Nigeria. This research explores the social and economic effects of urban sprawl in Kaduna metropolis. Remote Sensing and Geographic Information System (GIS) Technologies were applied for the analysis. The study found that Kaduna metropolis has experienced a progressive increase in the built-up area; in 2006 it had an aerial coverage of 13,980 hectares, a rise of 107.91% from 2001 aerial coverage of 6724 hectares. In 2012, the city had an aerial coverage of 15,808 hectares, an increase of 13.08% from 2006. Conversely, there has been a remarkable decrease in percentage of vegetation (1,458 hectares) and agricultural (11,739 hectares) land areas. In turn, such changes has adversely affected urban facilities or utilities such as pipe-borne water, electricity, health facilities, schools, security, transportation, wastewater infrastructures and fire safety services, which has become overstressed. Economic crisis has manifested in the rise of unemployment and escalating number of urban poor. Residential land use has encroached into open spaces while commercial activities overrun residential areas. Increase in distance and journey time make travel cost unbearable to the common man. These and social fragmentation retard livability in the city. Thus calls for a balance sustainable development in Kaduna metropolis and effective management of urban growth by the Kaduna Capital Development Board Authority. In due course, smart growth policy, growth management, urban containment, effective land use planning and public facility adequacy have been recommended to foster viable urban growth in Kaduna city and elsewhere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
