Is camel management an adaptation strategy under changing climate?
Such qualities of camels have attracted the interests of the non-camel herding pastoralists towards camel management as an adaptation strategy under changing climate. Megersa et al. ( 2008) have reported some production and reproductive performances of camel in Borana area.
What is the relationship between a camel and a human?
The camel and human become equal and consensual partners, each displaying responsibility for the relationship, each the caretaker of the other. The camel becomes capable of adeptly thinking and feeling its way through life in this human-made world.
Do we need to humanize ourselves before engaging with camels?
The information we share with each other about the best ways to be with camels usually includes a mix of fears, doubts, limits, hopes, and incomplete ideas about what camels are, and what they are “for”. Seldom discussed is the camel as an individual. And rarely considered is the need for further humanizing ourselves before engaging with camels.
What drives the evolution of human settlement preferences?
This evolution of human settlement preferences reflects the environmental constraints of early human settlement and the adaptation of human production to changes in human–land relations.
How are camels useful to humans?
The camel is used for several purposes for which its role is essential. It is used as a beast of burden for transporting goods and people as well as for providing milk. Milk is often the only regular food source for its owners. The camel's meat, wool and leather are also widely utilized.
How does camel help the environment?

What are 3 adaptation of camel?
Their adaptations include: large, flat feet - to spread their weight on the sand. thick fur on the top of the body for shade, and thin fur elsewhere to allow easy heat loss. a large surface area to volume ratio - to maximise heat loss.
How are camel affected by climate change?
As climate change alters the African landscape, making some parts of the continent unsuitable for agriculture, raising camels could supplant crops and other livestock in the hardest hit areas, a study from the International Livestock Research Institute suggests. Environmental scientist Philip K.
What is a camels value to people living in a desert climate?
They have been used for transportation, as a source of food and for protection for a very long time. Nowadays, they are hugely important in many parts of the arid world as sustainable livestock species (Burger, 2016). Camels are members of the Camelidae family.
Why are camels so important in the desert?
Camels are the most important animals in the Arabian deserts. They are used to carry heavy loads and to transport people. They are also used to plough and to work at water pumps. Camels supply milk and meat.
What are two adaptive features of camels?
Camels' adaptations to their desert lifestyle are well-known. Long eyelashes and elongated nostrils protect them from blowing dust and sand. Camels can survive without water for long periods of time, and energy-rich fat stored in their humps enables them to survive long periods without food.
What are the four adaptations of camel?

Can camels survive climate change?
Pastoralists confirmed that camels have high adaptive capacity to withstand the impacts of climate change, which reflects the high economic value of camels in terms of climate change adaptation and mitigation.
What is a camels climate?
No matter the type, camels are usually found in the desert, prairie or steppe. Though many people think that camels only live in hot climates, they do well in temperature ranges from 20 degrees F (minus 29 degrees C) to 120 degrees F (49 degrees C).
How do camels survive in the desert?
Extreme heat and cold are no sweat for a camel Camels are adapted to live in extreme environments, both hot and cold. Unlike a lot of other mammals, most of a camel's fat is stored in its humps, which allows for better thermoregulation. It makes it easier for them to release heat from their bodies in hot weather.
What do camels do?
Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel.

Are camels social animals?
Social Structure: Camels are social animals that live in groups, called herds. The herd consists of a dominant adult male, females, and their young. Other males that have been chased out of the group form bachelor herds. Camels communicate with each other with many sounds, such as moans and loud bellows.
How many camels are there in the Negev?
Today, there are approximately 4000 camels in the Negev, i.e., about two camels per 100 Bedouin, whereas, in 1955 to 1961, there were between 56 to 61 camels per 100 Bedouin (Table 1 ). The large difference in this ratio is mainly because of large fluctuations in the Bedouin population. Following the establishment of the State of Israel in 1948, the population of Bedouin plummeted from 65,000 to 11,000, while the number of camels stayed relatively constant. The decline in camel numbers after 1978 coincided with reduced functions of the camel. In addition, a peace agreement between Israel and Egypt was signed in 1979, which created a border between the Negev and Sinai deserts. The ratio of sheep to Bedouin showed some changes but was always greater than 1:1. By comparing the ratio of camels to sheep over the years, it emerged that the ratio has been declining and stands at about 1–2 camels per 100 sheep today, compared to about 15–17 camels per 100 sheep in 1955–1961 (Table 1 ). This trend of declining camel and increasing sheep numbers in Middle Eastern countries is in accordance with observations by Chatty ( 2013 ), who surmised that it may be related to the economy and urbanization of Bedouin: “ [i]n the 1920s and 1930s, sheep, the traditional herding animal of the ‘common’ tribes, began gradually to replace camels as the major herding animal of ‘noble’ tribes…The pattern, motivated by underlying economic and ecological considerations, came to be widespread throughout the region, particularly in present-day Saudi Arabia, Iraq, Syria and Jordan. The long-standing differentiation between ‘noble’ tribes as camel raisers and ‘common’ tribes as sheep raisers began to blur. The adaptation was viewed by many as a sign of decadence in Bedouin life, and a step in the direction of permanent settlement.”
What are the camel rides in the Negev?
Eight tourist sites in the Negev offer camel rides (Table 4 ), two with Bedouin owners and six with Jewish owners. These sites are generally staffed by Bedouin and offer Bedouin meals, accommodations (in tents and luxurious quarters), and workshops on Bedouin activities such as weaving and pita making. They can host large events such as weddings and bar/bat mitzvahs and can serve kosher food. Except for the Negev Camel Ranch and Succa Ha-Midbar, all sites earned less income from camel rides than from other activities.
Do camels live in Israel?
Almost all camels in Israel are owned by Bedouin (Ariel Ullman, chairman of the Society for Raising Camels in Israel, personal communication). It is compulsory for camels in Israel to be vaccinated against rabies and brucellosis and some Bedouin also vaccinate against tetanus and inject their animals against internal and external parasites. When vaccinated, each camel receives an individually numbered ear tag and is registered with the government and tax authorities. Most Bedouin are reluctant to register their camels and, consequently, many camels are not vaccinated. This has led to outbreaks of brucellosis traced to unpasteurized camel milk or camel milk products (Shimol et al. 2012 ). According to the Veterinary Services, 800 camels have been registered and, according to Ariel Ullman, about 3200 have not been registered, totaling a camel population of approximately 4000 camels, the lowest number of camels ever in the Negev. Ullman informed us that the number of camels has been declining mainly because the border between the Sinai and Negev was recently fenced and free passage of camels has ceased. In addition, many Bedouin are reluctant to raise camels because of recent tax laws. When asked whether the number of camels was increasing or decreasing in the Negev, most Bedouin informants (92% urban and 72% rural) agreed that it was decreasing (Table 2 ). Again, as noted above, the difference between urban and rural perceptions of camel numbers reflects lifestyle differences.
When were camels adopted?
Oral history indicates that camels have been adopted by the Borana pastoralists during the Gada of Abay Horro (1560–1568) following a period of severe drought (Angassa and Oba 2008 ). Therefore, the notion of climate change is not new to the Borana pastoralists.
How many camels are there in Ethiopia?
Ethiopia has approximately two million camels (CARE 2009 ), all owned by the pastoral communities (SOS Sahel 2010 ). The importance of camels has risen as a result of an increasing appreciation of their potential for milk production and ability to adapt to climate change (FAO 2010 ).
What has the drought of 2011 caused?
Hurst et al. ( 2012) have concluded that the drought of 2011 has caused starvation and death of many livestock in southern Ethiopia. Similarly, Oxfam International ( 2010) has reported that climate-induced recurrent droughts have caused the loss of thousands of livestock in Borana pastoral areas.
Do camels have milk?
During drought years and dry season periods when milk production from cows and goats becomes inadequate, camels remain reliable sources of milk for pastoralists. Moreover, in areas where water scarcity is the biggest challenge, camels are quite adapted and can stay for extended days without water (Farah 1996 ).
What is ICLEI in human settlements?

Why are residents so animated by these changes?
Residents are hugely animated by these changes because they can see the everyday wellbeing benefits they bring. Visionary public policies, coupled with cutting-edge innovations by business, have certainly played an essential role in creating the net zero human settlements of today.
How much of the world's population will live in cities by 2050?
With 70% of global population expected to live in cities by 2050 and bear the brunt of the climate crisis, it is critical that we get them right. The vision of a 1.5 degree resilient and equitable world and of a green and just recovery cannot be realised without cities at the heart of this transition.

1 Introduction
The land surface of the Earth is a finite resource that is central to human welfare and the functioning of the Earth's system. Human activities are transforming the terrestrial environment at unprecedented rates and scales across the globe ( Seto et al., 2011 ).
3 Results and discussion
The global data of human settlements in 1990, 2000 and 2014, reveal a gradual increase in the global area of human settlements over the past 25 years ( Fig. 1) from 310707.37 km 2 in 1990 to 460421.38 km 2 in 2014. Human settlements have grown in different areas across different continents.
Table 1
Life cannot develop without water. The growing global population has resulted in a large number of people flooding into coastal areas, placing great pressure on the ecosystem and its resources. We calculated the distribution of human settlements along the coastline and near terrestrial water bodies.
4 Conclusions
In the current study, we integrated GHSL and multi-source remote sensing data to analyze the temporal and spatial variations of global human settlements from 1990 to 2014 and under different geographical distributions. The key conclusions are described in the following five items.
