Desertification is caused by a number of different issues. A true environmentalist by heart ❤️. Climate change plays a huge role in desertification. The bare soil then easier dries out and turns to dust, which can be blown and washed away in a single storm. For example, up to 50 percent of the Canadian Prairies spreading over Alberta, Saskatchewan and Manitoba are likely to battle with some of the negative effects of desertification in the upcoming years. However, it is the paradox of life that especially in these vulnerable regions, animal herding is often the only livelihood people can have and there are no restrictions in place that would regulate the maximum number of animals for a given space. Be it true or not, unfavorable conditions still forced early people to leave their homes and everything they were familiar with. In those cases, there isn’t a lot that people can do except work to try and help rehabilitate the land after it has already been damaged by nature. And try to do everything in our power to help protect natural resources we have. (And 5 Ways to Reuse Old Bottles), Is Denim Eco-Friendly? Desertification is a process of degradation of the land. Unless you strongly believe in Elon Musk‘s idea of making Mars as another habitable planet, do remember that there really is no 'Planet B' in this whole universe. Once land turns from arable to arid, it is often on longer suitable for farming purposes anymore. Addresses the land issues identified by UNEP regional groups, and highlights the pressures of human demands on the land resource as the cause of land degradation. That means also less rain throughout the year. Let’s have a look where it all started and what are the consequences. Topsoil is crucial for plant growth because it contains most of the organic matter and 50 percent of important nutrients such as phosphorus and potassium. There are some cases where the land gets damaged because of natural disasters, including drought. When areas start to become desert, animals and people will go to other areas where they can actually thrive. Because of ambitious cotton farming projects in the dry Aral Sea basin that needed irrigation. One of the latest humanitarian crises has been declared in countries that have been dependent upon resources provided by lake Chad, where lake water gets quickly replaced by inhospitable sand dunes, destroying fishing and farming communities. (And Are They Compostable? Some farmers do not know how to use the land effectively. Humans degrade soils when they compact it, erode it, disrupt its organic and inorganic structure, raise its salinity, and cause desertification. Planting trees in those areas are quite important since they are natural carbon dioxide storage spaces; they slow down global warming and contribute to maintaining a natural balance. In many instances, these people go to larger cities, hoping for better life by finding a new livelihood. Some of these families then end up living in poverty in slums. Deforestation is one of the leading human causes of desertification. Greentumble’s writer Deogracias has described how is the problem of deforestation linked to the livelihood of some people in his country, Malawi. If an area becomes a desert, the water quality is going to become a lot worse than it would have been otherwise. In many cases, increased water runoff from desertified areas wreaks havoc on neighboring lands, eroding soils, damaging vegetation and making soils extremely vulnerable to encroaching desert. As “harsh” as this may sound, the reason is very simple. Therefore, planting trees in the affected areas not only prevents desertification but also fights against additional environmental issues. Our entire life support system depends on the well-being of … This is caused, and acts in concert with, a number of other factors — including drought, overgrazing, deforestation, common agricultural practices, and changes in the climate. And together with ecosystems disappear even natural resources that were once present. By putting these together, we can prevent the issue from becoming even more widespread in the areas that have already been affected. It is where we live, breathe, eat and raise our children. 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. By adding these to what we should be doing with land, we can ensure that we don’t turn the entire world into a desert. Desertification propels the loss of biodiversity on a large-scale. So much could be written about the effects of climate change on the health of our lands, as climate change can lead to land degradation for many reasons, and it is very often climate change that exacerbates the progress of desertification in increasingly many places. When ecosystems cease to support us and our livestock, only bad things happen. Pretty much every continent has some dryland area that is currently threatened by desertification if no immediate preventative measures will be taken. Land desertification, species extinction and climate transformation, these three problems all are a long term problem to the world. The main causes of desertification include: Population growth - the population in some desert areas is increasing. Flooding is not the only problem, sand storms are another big issue, mainly because wind-blown particles (including those that are polluted) can travel long distances and cause health problems to people even in distant urban areas. Deserts And Desertification The Causes And Consequences 1. The region currently faces extensive desertification caused by numerous factors. This causes crowding and overpopulation, which will, in the long run, end up continuing the cycle of desertification that started this whole thing anyway. When people gather and keep too many animals in one area, grasses start dying because their roots are often weakened by animals constantly stepping on them and plucking out newly re-growing parts before plants have time to grow resistant enough and to multiply. The reason is simple, people lost their ability to grow food, water resources became scarce and their animals got weak from not having enough to eat. The vast majority of desertification in the present day is caused by harmful human activity. These pollutants then remain deposited in the soil or wash off into rivers, creeks or lakes. The desertification results in a decline in population for which species may become endangered or even extinct. However, as the trend of urbanization increases, the demand for resources only grows bigger, drawing more and more resources and leaving behind degraded lands that easily succumb to desertification. What remains left is only a lifeless pile of dust instead of a life-giving medium. Their loss to buildings and other infrastructure is, therefore, rather wasteful. A rapid increase in human population, especially in vulnerable areas of Africa and Asia, has exceeded the recovery capacity of dryland ecosystems. Similar scenario has happened even with the Bedouins grazing their herds freely over the fragile steppe in Syria. Sustainable Practices to Prevent Desertification From Happening. Our planet’s ecosystems sustain life only when balanced. With plants dying, already scarce rainwater gets washed away instead of being drawn into the soil, which only scales up the problem as remaining plants do not have enough moisture to survive dry spells as they used to. This means that affected areas and even adjacent areas have compromised capacity of withstanding extreme weather events. In fact, in some areas overgrazing has led to complete desertification. Except causing damage, flood water also picks up many unwanted pollutants while making its progress through urban areas, landfills, wastelands, or agricultural lands where fertilizers and pesticides were used. Urbanization and Other Types of Land Development, 11. Why Is Biodiversity Important to Ecosystems. As desertification occurs, this most productive layer of the soil gets blown or washed away from the surface rather quickly because there is no vegetation that would protect it, and nutrients with organic material are lost for good. ), Can You Recycle Trophies? These negative events are directly linked to the wellbeing of people. Quick Navigation for The Major Causes and Effects of Desertification, [1] https://www.un.org/press/en/2012/gaef3352.doc.htm. Conserve Energy Future. In general, the destruction of habitats and desertification may also contribute to a loss of biodiversity. Animals will also go hungry, which will cause even more of a food shortage. While heavy machinery keeps spraying #monocrops with #pesticides and #fertilizers, millions of #family #farmers are applying agroecological approaches to redress those impacts and revive #rural areas. As we continue to remove natural vegetation from landscapes, we change radically the water absorption capacity of soils. 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. Soil erosion is often one of the final steps that closes the loop of continual soil deterioration that is difficult to revert. The problem of worsening desertification doesn’t have to be linked only to agricultural lands, unsustainable water management happens even in cities and tourist destinations that are build in arid or semi-arid areas. In turn, many farmers may lose their livelihood, since they often solely rely on farming as their single source of income. Causes of Desertification. Once the overexploitation takes place, desertification often follows, leaving behind only barren land and misery for those who haven’t left. UNCCD estimates that advancing desertification could displace globally 50 million people in the next 10 years [21]. Events such as flash floods, landslides and dust storms, become stronger in areas with heavily degraded soils. Also Know, what impact does desertification have on humans? As you may have noticed, desertification problems are often related and lead to one another. Causes Of Land Desertification. Over drafting is the process in which groundwater is extracted in excess of the equilibrium yield of the aquifer that is pumping or the excessive pulling up of groundwater from underground aquifers. In areas of low precipitation, like Sub-Saharan Africa, long droughts that turn arid land to unproductive, barren soil are a frequent cause of desertification. Majority of those who are affected the most by this problem are as usual the world’s poorest nations where people struggle daily with the direct impacts of climate turning against them, and deserts claiming more of their already scarce soils. Additionally, artificially added water also rises otherwise low groundwater level which in turn dissolves even more salts [7]. Increased salinity happens because irrigation water mobilizes naturally occurring salt in these soils. Dust particles in the atmosphere can scatter incoming radiation from the sun, reducing warming locally at the surface, but increasing it in the air above. 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. Unfortunately, that’s not always the case, as they often lack the skills that are needed for urban jobs. 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. And when you think about it, it’s just a natural reaction of any living organism to survive – “fight or flight.”. Without farms in these areas, the food that those farms produce will become much scarcer, and the people who live in those local areas will be a lot more likely to try and deal with hunger problems. Land degradation due to urbanization has affected strongly many countries such as Egypt, Iraq, Turkey, Spain and other places with hot climate, where urban and tourist areas spread along the rivers or coastlines, sealing these lands and pushing farming away onto marginal lands, which will only accelerate their desertification over the time [11]. Most of the agricultural land in the country has increased salinity due to large-scale irrigation plans and progressively drier climate. Loose soil buries plants or exposes their roots to the sun, so they cannot fulfill their function. Desertification affects topsoil, groundwater reserves, surface runoff, human, animal, and plant populations. Duanyang Xu, Xiaogang You, Chunlin Xia, Assessing the spatial-temporal pattern and evolution of areas sensitive to land desertification in North China, Ecological Indicators, 10.1016/j.ecolind.2018.10.005, 97, (150-158), (2019). If an area of land has natural resources like natural gas, oil, or minerals, people will come and mine it or take it out. Examples of civilizations that met their doom due to droughts include the Carthage Civilization, the Harappan Civilization, people groups in Ancient Greece, the Roman Empire, and people groups in Ancient China [22]. Just look at previously mentioned examples, they all point to this conclusion. Founded Conserve Energy Future with the sole motto of providing helpful information related to our rapidly depleting environment. Forests are being chopped down at an alarming rate, leading to massive desertification in various regions of the planet. We already have the statistics for the future: the growth percentages of pollution, overpopulation, desertification. Let us know if you liked this article. However in the long run the soil would gradually lose its nutrients, land is degraded and desertification creeps in. 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. Endangerment and Extinction of Species, 1. There is probably no need to explain how crucial these services are for our wellbeing. Furthermore, additional problem arises from the space problems. This usually strips the soil of nutrients, which in turn kills the plant life, and eventually leads to the process of becoming a desert biome as time goes on. Therefore, it is important to realize after reading this article how valuable soil conservation is. Due to unrestricted grazing of the steppe by livestock combined with the influence of climate change, Syrian land has become so damaged that it has turn into lifeless dust. In the long run, this may turn from arable into arid land over time, and it will no longer be suitable for farming purposes after a few years of excessive farming since the soil has been damaged too much over time.
