Why is land use change bad?
Detrimental changes in land cover and land use are the leading contributors to terrestrial biodiversity loss . These changes generally occur slowly, but they are associated with declines in species diversity and populations, and can have a major impact on ecosystems.
How does human land use affect the environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation . Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
How does land use affect local population?
Human population growth together with competitive land use causes land scarcity , conversion of wild lands to agriculture and other uses. ... Human influence on the land and other natural resources is accelerating because of rapid population growth and increasing food requirements.
What are the impacts of land use change?
Land use and land cover changes have significant environmental consequences at local, regional, and global scales. These changes have intense implications at the regional and global scales for global loss of biodiversity, distresses in hydrological cycles, increase in soil erosion, and sediment loads [1].
How does land affect climate?
An increase in the elevation, or altitude , of a land mass also makes for a cooler climate. Increases in altitude mean thinner air, which makes the atmosphere less able to absorb and retain heat. ... This affects local climate, since moist air retains heat longer than dry air.
