The area potentially could be turned into a desert in the future as aridity levels increase. This is leading to a decrease in population. The people who live in the Sahel are some of the poorest people on earth, this is contributed by the incredibly hostile conditions/environment (high temperatures and low unreliable rain rainfall). This means the area of the Sahel is barely able to support any life at all. The immediate cause is the removal of vegetation, the removal of vegetation happens due to a number of factors.
Similarly in Boscastle, farming in upper course had led to deforestation and removal of hedgerows decreasing the amount of interception from higher ground. Also most of the land and hills were made up of impermeable slate and clay soil which decreased the capacity of water that the ground is able to absorb. Additionally, in both these places, there were converging rivers. In Boscastle there were three; the Valency, Jordan and Paradise. Similarly in Thailand, large
The general size of Russia meant that most of it was uninhabited due to the poor infrastructure and travel availability, which was restricted due to the roads being mainly dirt which, in bad weather (which was generally most of the Russian climate), the roads would turn to mud and make them completely undrivable. This would mean that keeping in contact with the thousands of state governments and such would be almost impossible, as there would be next to no communication, and if there was, it would arrive weeks late, creating confusion and little advancements. Also, three quarters of the Russian population were peasants, who owned small plots of land, which could be traded and bought by other landowners. However, these were eventually freed, and each owner got a small plot of land and in return, had to pay an amount of money to the government, which meant a lot of small farms were in debt. This meant that the Russian agriculture was poor and the remaining farms used outdated methods and had no advancements for a while, due to illiteracy and such.
There are more than one seventh people who do not have enough nutrition from their food on earth today. In addition, shortage of water and land which could affect the food production is one of the critical problems over the world (FAO, 2009b). Wasting too much water and water pollution cause decreasing water resource in daily life. Urbanization has witnessed the fading away of many farm lands. What is more, lower yield in less-developed countries leads to ‘yield gap’ in agricultural production (Godfray, 2010).
Overgrazing- with less rain fall than normal, animals graze and consume more vegetation that what is being produced. This results in the land becoming barren because there are not enough nutrients to support vegetative growth. Overgrazing can lead to soil erosion and desertification on the land. To reduce these practices people can be more responsible be following a grazing management schedule. Some grasses grow well during the summer and some grow well during the cooler months.
In summer the trench would be exposed to the hot sun and in winter to pouring rain and snow. The rain filled up the trench and water seeped in through the sides leaving the troops up to their knees in thick, stinking mud that made any movement difficult. There was no sanitation and rats were a problem in the trenches. Diseases were bad such as dysentery and trench foot. There would be no relief for front line troops for weeks on end.
A major crises for western Europe was demography. During the end of the 1300's and beginning of the 1400's the population of western Europe grew out of control. It was overpopulation that led to major problems for western European society. With a growing population food became scarce and people were not getting the nutrition they need. Food shortages were spreading throughout and people were easily getting susceptible to sickness and disease.
It was an acute and highly infectious disease and the fatality rate for this unexposed population was often high. 2.Malnutrition Indigenous people also suffered from malnutrition. They lost the traditional lifestyle and their diets were altered due to the European’s growing settlement. Tress and plants were destroyed,waterways were dirtied, and the large animals escaped. The land was no longer able for them to hunt and gather food and they couldn’t to the new food such as sugar and flour.
The ecological downfalls is where it hurts us today. The environment is in danger, it hurts our elk and birds for mistaken of food leaving them dead. It melts into our streams, rivers and other drinking water resources. It mixes with our water changing its salinity levels. The ice melts and the water doesn’t just disappear, this is a problem that could easily be solved but because it’s too much work for the people to lift a shovel the environment must suffer.
This can lead to heavy traffic; vast amounts of waste, a lack of food, water and housing which are all the characteristics of an unsustainable city. However, these problems can be dealt with when a city has good urban planners, consolidative infrastructure and the capacity for change and development as demonstrated in the city of Stockholm, which shows that developing a sustainable city is possible. The city of Mumbai in India is highly unsustainable. Its population has increased by 10 million people in the past 30 years turning it into a mega city with a population of over 20 million people. Due to the rapid increase in population, the city has not had time to develop to the vast numbers of people who now inhabit it.
