(v) Construction of roads, railways and other infrastructure.
(vi) Mining and quarrying activities.
(vii) Population growth and increasing demand for land.
(7b)
(PICK ANY THREE)
(i) Reduction in agricultural productivity: Deforestation exposes the soil to erosion and loss of nutrients, making the land less fertile. This reduces crop yield and affects livestock grazing. Farmers are forced to spend more on fertilizers or move to new land, leading to lower food production and possible food shortages.
(ii) Loss of biodiversity: The destruction of forests leads to the loss of habitats for many species of plants and animals. Some organisms may become endangered or extinct due to the absence of shelter and food. This reduces biological diversity and disrupts the natural balance of ecosystems.
(iii) Soil erosion and land degradation: Removal of forest cover leaves the soil exposed to wind and heavy rainfall. The topsoil is washed away, resulting in gullies and reduced soil fertility. Continuous erosion can make the land unsuitable for farming and other productive uses.
(iv) Climate change and global warming: Trees absorb carbon dioxide from the atmosphere. When forests are destroyed, more carbon dioxide remains in the air, increasing the greenhouse effect. This contributes to rising temperatures, irregular rainfall, prolonged droughts, and other extreme weather conditions.
(v) Flooding: Forests help absorb rainwater and reduce surface runoff. When trees are removed, rainwater flows rapidly over the land, increasing the risk of floods. Flooding destroys homes, farmlands, roads, and other infrastructure while causing loss of lives and property.
(vi) Desertification: Continuous clearing of forests, especially in dry regions, exposes the land to intense heat and wind action. Over time, the soil becomes dry and infertile, vegetation disappears, and desert conditions gradually spread into formerly productive areas.
(vii) Disruption of the water cycle: Trees release water vapour into the atmosphere through transpiration, which helps in cloud formation and rainfall. Deforestation reduces this process, leading to decreased rainfall, drying up of rivers and streams, and shortage of water for domestic, agricultural, and industrial use.

The high cost of updating software and replacing obsolete equipment also discourages the widespread adoption and effective use of GIS technology across the country.
(ii) Inadequate skilled personnel: GIS is a highly technical field that requires trained professionals with knowledge of cartography, remote sensing, computer programming, database management and spatial analysis. Nigeria has an inadequate number of qualified GIS experts due to limited training opportunities and insufficient investment in capacity building. As a result, many organizations depend on a few specialists or foreign experts, leading to delays in project execution, poor data analysis and inefficient use of GIS technology.
(iii) Inadequate and unreliable data: Effective GIS application depends on the availability of accurate, current and comprehensive geographical data. In Nigeria, many maps, land records and spatial databases are outdated, incomplete or inaccurate because they are not updated regularly. Some areas also lack proper geographical information due to poor surveying and data collection. This reduces the reliability of GIS analysis and may lead to poor planning, wrong decisions and ineffective implementation of development projects.
(iv) Poor power supply: GIS operations rely heavily on electricity to power computers, servers, GPS equipment and other electronic devices. However, the irregular and unstable power supply in Nigeria frequently interrupts GIS activities, causes loss of valuable data and damages expensive equipment. Many organizations are forced to depend on generators and alternative power sources, which increase the cost of operating GIS systems and reduce overall efficiency.
(v) Poor funding: Adequate funding is essential for acquiring modern GIS equipment, purchasing software licences, collecting spatial data, conducting field surveys and training personnel. In Nigeria, many government agencies and research institutions receive insufficient financial support for GIS-related projects. This lack of funding limits the expansion of GIS programmes, delays project implementation and prevents regular updating of equipment and databases needed for effective planning and development.
(vi) Poor internet and communication facilities: Modern GIS applications often depend on reliable internet services for downloading satellite imagery, sharing geographical data, accessing online databases and communicating with other institutions. In many parts of Nigeria, internet services are slow, unreliable or completely unavailable. This makes it difficult to exchange information quickly, delays GIS projects and reduces the efficiency of data analysis and decision-making.
(vii) Lack of public awareness: Many people, including government officials, policymakers and members of the public, have little knowledge of the importance and benefits of GIS technology. Because of this limited awareness, GIS is often given low priority in development planning and government policies. Many organizations also fail to invest in GIS because they do not fully understand its usefulness in solving environmental, agricultural, transportation and urban planning problems.
