Human settlements can influence ecological flows and landscape integrity of nature reserves (Xun et al., 2014). Expansion of human settlements inside nature reserves causes habitat loss and fragmentation (He et al., 2014; Merlín-Uribe et al., 2013).
How does expansion of human settlements affect nature reserves?
Expansion of human settlements affects nature reserves in multiple ways ( Castro-Prieto et al., 2017; Joppa et al., 2008 ). Human settlements can be found inside and outside of nature reserves. Globally, 95% of nature reserves were near inhabited areas and 421.9 (±246.4) million people lived inside nature reserves by 2009 ( Mora and Sale, 2011 ).
How do environmental factors affect human settlements?
He has a Masters in Education, and a Bachelors in Physics. Environmental factors create either livable or unlivable conditions which influence where humans decide to settle and why. Learn more about the role of Agrarian societies in determining where humans settle, and how resources or events draw people to areas to live.
What is the relationship between human settlement and landscape fragmentation?
Besides causing land loss, the expansion of human settlements within nature reserves also increases landscape fragmentation. Under the scenario of high growth and weak protection, the mean ECON value in 367 nature reserves is 3 times higher than the value in 2010 while the mean AREA_MN is 0.4 times smaller.
Are nature reserves more susceptible to human impacts?
Various studies have shown that smaller reserves are more susceptible to human disturbances than larger ones ( Hansen and DeFries, 2007; Maiorano et al., 2008; Mckinney, 2005 ). Another potential reason is that many county-level nature reserves have been set up without careful planning ( Liu, 2006 ).

What are human impacts?
Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans.
Does human settlement affect climate?
More energy from the sun is absorbed and released by these urban surfaces which increases the average overall or ambient temperature for the urban area. This 'urban heat island effect' can raise the air temperature in a city by 1- 4 C degrees.
How human impacts affect the biotic and abiotic features of an ecosystem?
Human activities have caused serious environmental problems, polluting natural resources and disrupting ecosystems. Deforestation, urbanization, and agricultural practices are some of the ways in which humans have greatly changed the Earth, affecting both the abiotic and biotic environment.
What are 3 types of human settlements?
There are various types of settlements for eg; Scattered settlements, Nucleated settlements and Linear settlements.
How does human settlement disturb the surrounding and its effects?
On the most basic level, the interaction of human settlements on the environment is that they extract non-renewable natural resources on the one hand and on the other, produce waste products and pollution that has to be absorbed by the natural environment.
How does informal settlements affect the environment?
Informal settlements are characterized by a lack of basic services, pollution, overcrowding and poor waste management. These characteristics impact negatively on the environment posing risk and susceptibility to health problems associated with informal settlements.
What are the different types of human settlements?
Human settlements can broadly be divided into two types – rural and urban. Rural settlements: Rural settlements are most closely and directly related to land. They are dominated by primary activities such as agriculture, animal husbandry, fishing etc. The settlements size is relatively small.

How do factory farms affect the ocean?
The massive, concentrated amounts of waste these factory farms generate are beginning to run off and devastate aquatic ecosystems and other water sources. Off the coasts and farther out into the oceans lie dead zones. These are patches of water that are so polluted and poisoned that they can no longer support marine life. Caused by the runoff of different chemicals like garden fertilizers and industrial waste, ocean dead zones have been a growing problem. While action needs to be taken to reduce the runoff made directly by humans, some of the largest contributors to this sickening problem are factory farms.
How does desalination affect the environment?
The construction of desalination plants and its function has an overall negative effect on the environment since it harms the biodiversity of the nearby ecosystems through the desalination process.

What are the causes of environmental degradation?
According to www.conserve-energy-future.com, the first factor causing environmental degradation is overpopulation. Rinkesh, World’s Top Eco-Conscious Bloggers and website owner, stated that overpopulation leads to excessive consumption of goods and necessities which impacts natural resources. This is because more people demand more food, clothes, shelter and fuel. Because of this demand, their living space needs to be expanded in order to grow food and provide homes for people.
Why are natural resources important?
Natural resources and water remain vitally important to this day. Humans can't live without fresh water and still can't farm without it, so it's a necessity. Though less important with the invention of indoor plumbing, it's still a major consideration. But in the last few hundred years, water and soil were replaced with many other natural resources of importance.
What natural resources allowed us to manufacture and build our products?
The presence of wood, stone and metal ores allowed us to manufacture and build our products. And because these natural resources could be sold, a settlement located near any of these things tended to do very well for itself. And then there were the rarer, expensive natural resources, like gold, silver and oil.
Why Do Humans Live Where They Live?
Over 12,000 years ago, humans were hunter-gatherers. We lived a nomadic lifestyle, moving from place to place over the seasons and years. Considering humans have been around for hundreds of thousands of years, the way we live now - settling down in one place for long stretches of time - is a pretty new lifestyle. But if you're going to settle down, you have a lot of places to choose from. So, why did we choose to live where we did? And what decides where we live today?
What are environmental factors?
Environmental factors create either livable or unlivable conditions which influence where humans decide to settle and why. Learn more about the role of Agrarian societies in determining where humans settle, and how resources or events draw people to areas to live. Updated: 11/07/2021
Why are people drawn to Northern Canada?
But it's not just natural resources and money that attracts people to an area, because they have to actually live there. A warm, temperate and pleasant climate can be attractive to people. There was never the same number of people migrating to Northern Canada as there were to the United States, and climate is a big reason for that.
Why was the gold rush so important?
And then there were the rarer, expensive natural resources, like gold, silver and oil. The gold rush was a rapid movement of people because of the discovery of gold, especially to California and other parts of the Western United States in the 19th century. When we discovered gold, people saw their opportunity to get rich and rushed to find their own piece of the prize.
What are the natural resources that attract people to an area?
And then there were the rarer, expensive natural resources, like gold, silver and oil. But it's not just natural resources and money that attracts people to an area, because they have to actually live there, too. A warm, temperate and pleasant climate can be attractive to people.
How do human settlements affect nature reserves?
Expansion of human settlements affects nature reserves in multiple ways ( Castro-Prieto et al., 2017; Joppa et al., 2008 ). Human settlements can be found inside and outside of nature reserves. Globally, 95% of nature reserves were near inhabited areas and 421.9 (±246.4) million people lived inside nature reserves by 2009 ( Mora and Sale, 2011 ). Human settlements can influence ecological flows and landscape integrity of nature reserves ( Xun et al., 2014 ). Expansion of human settlements inside nature reserves causes habitat loss and fragmentation ( He et al., 2014; Merlín-Uribe et al., 2013 ). It was predicted that the expansion of human settlements would convert 290,000 km 2 of natural habitats globally between 2000 and 2030 ( Mcdonald et al., 2018 ). Downsizing and downgrading of nature reserves consequently reduce the effectiveness of natural conservation ( Mascia and Pailler, 2011 ). Human settlements around nature reserves increase the isolation of reserves in a heterogeneous landscape ( Bailey et al., 2016; Castro-Prieto et al., 2017) and human activities can threat conservation targets ( Mcdonald et al., 2009; Ye et al., 2015 ). For example, night light from nearby human settlements has been found to affect the distribution of species, community structure, and ecosystem functions in nature reserves in Europe, Asia, and South and Central America ( Gaston et al., 2015 ).
How does the expansion of human settlements around nature reserves affect the environment?
Our results show that even assuming strong protection of nature reserves, i.e., no development inside nature reserves and no development across the boundaries, the expansion of settlements around nature reserves can increase threats to protected objects. Observations on the ground support this possibility. For example, wildlife in Shimenshan Nature Reserve in Guangdong has been threatened by persistent halogenated compounds emitted by nearby electronics manufacturing and assembling centers ( Peng et al., 2015 ).
What are nature reserves?
Nature reserves protecting forest ecosystems, wetlands (only include inland wetlands), and wild animals are affected more than other types of nature reserves. Table 1. Nature reserves that may be affected by the expansion of human settlement in China by 2050 (Numbers listed above are affected areas with a unit of km 2.
How was land use data collected in China in 2010?
The land use data was generated by using coupled IMAGE and FLUS models ( Li et al., 2017 ). We extracted out the class of urban and built-up from the 2010 data and treated it as the area of current human settlements. For future human settlements, we extracted out the class of urban and built-up from the 2050 data under A2 (high GDP and population growth with rapid technological innovation) and B2 (low GDP and population growth with slow technological innovation) scenarios ( Sohl et al., 2012 ). The two scenarios represent two ends of socioeconomic development and thus contain the possible range of land use changes. The gridded land use data has a resolution of 1 km and a WGS84 Web Mercator projection.
How many nature reserves will be occupied by human settlements?
Assuming weak protection and high growth, 5016 km 2 of lands in 357 nature reserves may transform into human settlements. Among them, 243 of nature reserves will lose lands to human settlements for the first time while the rest will experience further encroachment by existing human settlements. Compared to 2010, the number and area of affected nature reserves increase by 191% and 1016%, respectively. Under weak protection and low growth, 99 nature reserves may loss 379 km 2 lands. Among them, 37 will have lands occupied by human settlements for the first time, while the rest experiences more loss. Compared to 2010, the numbers and loss of area increase by 29% and 71%, respectively. Under strong protection, the land occupied by human settlements will stay the same as in 2010 for both high and low growth scenarios. The multiple comparison results show that the land occupied by human settlements under the scenario of high growth and weak protection is significantly different from other situations ( Fig. 1 a).
How are nature reserves important?
However, many small nature reserves are very important for biodiversity in China as they provide refugees for key species ( Wu et al., 2011 ). A recent global analysis also indicated that small and isolated habitats are important for conserving the world's biodiversity ( Wintle et al., 2019 ). Innovative management measures such as co-management by local non-government organizations and residents ( Huang et al., 2018) can be explored to enhance protections of small nature reserves. Local scientific research institutions, investors, and residents should be encouraged to collaborate on finding innovative management measures ( Oldekop et al., 2016 ).
How many nature reserves will China have by 2050?
Expansion of human settlements can affect 718 nature reserves in China by 2050. Nature reserves face increased risk of land loss, fragmentation, and human threats. Sizes, administrative levels, protection types, and geographic locations of nature reserves are mediating factors.
