How does climate change affect urban settlement?
Rising global temperatures causes sea levels to rise, increases the number of extreme weather events such as floods, droughts and storms, and increases the spread of tropical diseases. All these have costly impacts on cities' basic services, infrastructure, housing, human livelihoods and health.
How climate affects settlement and human activities?
Climate change impacts on African human settlements arise from a number of climate change-related causes, notably sea level changes, impacts on water resources, extreme weather events, food security, increased health risks from vector home diseases, and temperature-related morbidity in urban environments.
How does climate affect informal settlement?
Thus, the conditions of life in informal settlements elevate risk from most climate change impacts such as higher (and increasing) maximum temperatures and heat waves, more intense precipitation events and riverine floods, wind storms with higher wind speeds, changes in water availability and sea-level rise.
How do warmer temperatures affect settlements?
Warmer temperatures may allow more settlements farther north in Canada, Europe, and Russia. The increase in temperature may make transportation easier in places that are frozen most of the time, such as western Siberia in Russia. This may result in more people deciding to settle there.
How does the environment affect settlements?
Settlement structure is a driver of environmental change as it influences the amount of natural land that is converted into human habitation, the demand for non-renewable natural resources and the production of pollution and waste.
What are the factors that affect settlement?
In order to better categorize which factors ultimately affect settlement, geographers have generally accepted four umbrella terms to describe these elements: climatic, economic, physical, and traditional.
What are the effects of a flood in an informal settlement?
Impacts from flooding include loss of informal housing, inundation, soil erosion, poor water quality, injury and death, as well as disruptions to livelihoods and city economies, damage to homes, assets and public infrastructure, population displacement, and the spread of diseases.
Why informal settlements are often hardest hit by flooding?
For example, most of the informal settlements lack stormwater drainage channels that are designed and built to engineering standards. The lack of stormwater drainage channels in settlements that are rapidly densifying is a major cause of flooding.
How can informal settlements be prevented?

How is climate change affecting people?
The impacts of climate change on different sectors of society are interrelated. Drought can harm food production and human health. Flooding can lead to disease spread and damages to ecosystems and infrastructure. Human health issues can increase mortality, impact food availability, and limit worker productivity.
What are the effects of human activities on weather?
There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to ...
