desertification causes and effects

This can cost a lot of money to try and do, so many farmers will have to sell their land and leave the desert areas. The reasons why this has happened are longer periods of droughts and the overextraction of water for irrigation and mining projects [12]. Desertification has destroyed even lives of nomadic Bedouins and farmers in Syria. And when you think about it, it’s just a natural reaction of any living organism to survive – “fight or flight.”. While farmers despair about their inability to cultivate rice fields, local agronomists confirm that it was the water overextraction to create rice paddies that has significantly contributed to the current desert expansion [10]. Some farmers do not know how to use the land effectively. There have been many records of water scarcity and pollution problems that are linked to desertification or other forms of land degradation across dry African and Asian countries. Since our world population is continuously growing, the demand for food and material goods is also increasing at an alarming rate. Overpopulation and overexploitation of natural resources, Famine, poverty and political instability, Increased vulnerability to natural disasters, Rise of famine, poverty and social conflicts, Caused historical collapses of civilizations, The official definition by the United Nations Convention to Combat Desertification (UNCCD), likely to battle with some of the negative effects of desertification, “We have been almost buried: the Sudanese villages being swallowed by sand.”, the NASA Goddard Institute for Space Studies, Lessons from the Past: Civilizations Lost Due to the Environmental Destruction, ‘Desertification: The invisible frontline’. Without food and water, it becomes harder for people to thrive, and they take a lot of time to try and get the things that they need. This is because people on the brink of famine, extreme poverty or political instability in their country need to solve the crisis at the moment and do not think about sustainable cultivation strategies. Drylands, the most susceptible areas to desertification, are characterized by a scarcity of water during certain periods of the year. UNCCD Newsletter, no. It can also cause issues with the soil due to chemicals and other things that may harm the ground. While some species may be able to adjust to the altered environmental conditions properly, many species will not be able to do so and may suffer from serious declines in population. 1. It means that the effects of desertification can be extremely serious and not only for us, but for the balance of the whole planet. According to UNESCO, one-third of world’s land surface is threatened by desertification, and across the world, it affects the livelihood of millions of people who depend on the benefits of ecosystems that drylands provide. In turn, many farmers may lose their livelihood, since they often solely rely on farming as their single source of income. In those cases, there needs to be research and application of the latest technology that pushes the limits of what we currently know about the drivers of desertification. Groundwater is the freshwater found underground and also one of the largest water sources. Events such as flash floods, landslides and dust storms, become stronger in areas with heavily degraded soils. Animal grazing is a huge problem for many areas that are starting to become desert biomes. After desertification, regions suffer from water shortages due to climate change and animals may suffer and die since water is vital for all life on our planet. Extended droughts, prolonged flooding or sudden extreme changes in temperature can deplete food sources of species causing starvation. The desertification implies the destruction of the livelihood of farmers. Endangerment and Extinction of Species, 1. As the days get warmer and periods of drought become more frequent, desertification becomes more and more eminent. Our goal is to inspire people to change their attitudes and behaviors toward a more sustainable life. This problem becomes even worse when large areas of land that are currently used for farming will then no longer be suitable for farming due to a lack of water triggered by global warming. Overgrazing is the major cause of desertification worldwide. Desertification often causes rural lands to become unable to support the same sized populations that previously lived there. In dry regions, grass and other small vegetation is necessary to keep the soil in place to prevent erosion and further damage to the soil. 2. Desertification is the degradation process by which a fertile land changes itself into a desert by losing its flora and fauna, this can be caused by drought, deforestation, climate change, human activities or improper agriculture. ), Can You Recycle Lotion Bottles? Our overall level of consumption is also increasing at a steady rate. By the time most of the natural resources have been extracted, and mining practices are no more profitable, the soil gets damaged significantly, and the land becomes arid, which may not be recoverable, and desertification occurs. The word ‘desertification’ may seem like a word depicting a very distant and abstract environmental problem that most of us do not consider being important in our daily lives. By taking that critical look at desertification, we have the tools that we need in order to get through the processes effectively. Can You Recycle Photos? Desertification is another major environmental concern and a significant barrier to meeting basic human needs in drylands and is being constantly threatened by increases in human pressures and climatic variability. This results in mass migrations out of rural areas and into urban areas (urbanisation), particularly in Africa. In fact, in some areas overgrazing has led to complete desertification. Some causes of desertification are natural, whilst others are human derived. The direct cause of desertification is poor land use. They are the ones who have seen the ugly face of desertification slowly reaching their doorstep, and they are the ones who are also witnessing how fast sand and dust consume even more land every year. Formerly, the second largest lake in Bolivia filled with diversity of fish and birds had completely dried up just in the span of three years, 2014 to 2017. Forests are being cut down at much larger scale than ever before, to be used as fuel, to provide products we use in our daily life, or to simply create more space for agriculture to sustain growing human population. Or, to put it in another way, desertification results in persistent degradation of dryland and fragile ecosystems due to man-made activities and variations in climate. The use of excessive amounts of fertilizers and pesticides to maximize their crop yields in the short term often leads to significant damages for the soil. © 2021 .
