This study evaluates built-up growth at Usmanu Danfodiyo University in Sokoto between 2007 and 2015. Primary and secondary sources were used to gather the data for this study. Field observations, interviews, and satellite images are the main sources of data. While secondary data are information that has been published and is relevant, such as books, articles, reports, dissertations, and the internet. Satellite image processing, image classification, overlay operations, vectorization, and digitizing are the techniques used. The study found that built-up expansion is more prevalent in the study area’s north-east and eastern regions, as well as to a lesser extent in the central region. According to the analysis’ findings, there are 208 structures totaling 145,715 square meters in 2007. As opposed to 2015, when 50 structures raised over a 92,328 square meter area. 250 structures in total, covering a total area of 238,044 square meters. To maintain and sustain the original master plan, it is advised that management seek out sufficient funding.



1.0          Introduction

Built-up refers to populated areas, whereas Expansion refers to a region through which something is made larger (Advanced English Dictionary).

Developed areas have been growing all over the world. Monitoring and predicting the built-up is crucial for both economic development and ecologically sustainable development of a region. They also serve as sentinels of environmental decline. (ARER, 2003).

Urban areas housed nearly half of the world’s population in 2000, despite taking up only 2% to 3% of the planet’s surface. The urban-rural border’s landscape is being drastically altered by the rapid growth of urban areas, which amplifies the severity of the ecological footprints of cities. The total area of productive land and water needed to produce something continuously is referred to as the ecological footprint. wherever on Earth that land is located, all the resources used and all the wastes assimilated by a specific population. Various Kitzes (2007). Over three-quarters of the world’s resources are consumed by the wealthy quarter of the population, and cities likely contribute at least 70% of the world’s overall resource depletion and pollution. (1996, RWWMEIA). The ecological footprint of North Americans, for instance, is 4-5 ha/capita, which is three times their just share of the Earth’s resources. Similar to the Netherlands, where the footprint per person is 3.3 ha, Japan has a footprint that is roughly eight times larger than its total domestic territory. If measured, Lenzen and Murray discovered that Australia’s ecological footprint is approximately 13.6 ha/capita.

regarding the actual use of all types of land. These footprints are connected to the creation of non-farm employment opportunities and the transition to higher-value farm products (like vegetables, fruits, or livestock) to satisfy urban consumers’ demands.

On the other hand, the provision of landscape amenities and environmental services places significant demands on the ecological system in terms of resource extraction, waste disposal, and pollutant discharge. In order to meet the demand for land for housing, industry, infrastructure, and recreation, it is estimated that one to two million hectares of cropland are taken out of production each year in developing countries as a result of urbanization. A number of the most significant urban transformations in history occurred during the 20th century. Earth’s terrestrial environments through time. Various Lenzen (2007).
