This is an invited paper in commemoration of the 2017 World Water Day organized by UNICEF in collaboration with Local Governments in Ekiti State, Nigeria.

Hand-dug wells (HDWs) are a major source of water supply in developing nations. This is consequent upon the failure of government to provide safe water to the people. This paper looks at the vulnerability of HDWs in the core area of Akure, Nigeria. The study area is made up of 11 residential quarters with 1149 buildings; 10% of buildings and five w...

Peri urban zones are areas capable of promoting urban and rural livelihoods and coping with the pressure and dynamics of population and land use changes. On the other hand, they constitute areas that lead to progressive degradation of the environment and collapse of institutions. This study examined the drivers of growth, characteristics and enviro...

Urbanization and increase rate of poverty coupled with the challenges of insecurity in most developing countries have led to increase of crime incidence. This phenomenon is not new to residents of Nigeria cities; it has created unrest and great burden. Consequently, this calls for the development of new approaches to tackle crime incidence in citie...

This paper aimed at assessing drought occurrences and its effects on vegetation cover in Sokoto State, Nigeria using geospatial and statistical techniques. Monthly precipitation data which span through a period of 40 years (1980-2010) and 30 years (1982-2011) respectively were used for generating Standardized Precipitation Index (SPI) graphs and ma...

This research attempts to bridge the gap between the old and modern fashion of keeping and storing criminal data by investigating the level and spatial analysis of crime occurrence in Akure, Nigeria with a view to promoting security in the city. The responses obtained from the administered copies of the questionnaire were coded and entered into Mic...

This study examines the extent to which community participation influences community ownership of water project and its sustainability in Ikaram Millennium Village (MV). Structured close-ended questionnaire and semi-structure open-ended interview checklist were used to elicit information from respondents including households, key informants, MV off...

The use of satellite imageries and spatial analysis techniques have not been comprehensively explored and exploited in capturing baseline information for monitoring of ecologically fragile areas in most developing countries including Nigeria. This study used Landsat imageries of Akure 1986, 2002 and 2011, and topographical map, DEM, GPS points, mea...

Ancient city centres are characterised by inadequately planned/unplanned land use and unsecured tenure system, leading overtime to the development of different forms and grades of slum in and around urban core area. This research studied the slum in the urban core of Akure, Nigeria deploying tools of Geographic Information System for comprehensive...

Socioeconomic characteristics of the people are indicators of their quality of life. Likewise, societies have traditional views and taboos about sanitation in general and faeces in particular. The impacts of poor sanitation and hygiene cost the Nigerian economy about 445 billion naira annually. In recent years, urbanization has phenomenally increas...
