Desertification is taking place much faster worldwide than historically and usually arises from the demands of increased populations that settle on the land in order to grow crops and graze animals. It negatively affects food production, livelihoods, and the production and provision of other ecosystem goods and services. Desertification is reversible, but that requires proper indicators to send out alert s about the potential We need to follow what is happening in the Sahel, in India, in China and in the other menaced areas, such as the ones in the Mediterranean Arch, the south of Africa, Central America and large Andean areas. Food Insecurity Desertification is a complex topic. Desertification imposes an additional constraint on human well-being by further reducing the limited ecosystem goods (e. g. , food, timber, water) and services (e. g. , soil maintenance, erosion control, carbon sequestration) that drylands provide. ... For a long time, rocky desertification and soil erosion in Xichuan County have caused serious damage to the local ecology and environment, adversely affecting social and economic development. Desertification is land degradation in drylands that affects biological productivity as well as the livelihoods of millions of people. separately, if policies for addressing desertification are to be effective. Desertification manifests in negative agricultural, environmental and health effects, which are all indicators of poverty. Finding 2. Desertification is the persistent degradation of dryland ecosystems by variations in climate and human activities. The effects of desertification ultimately have negative effects on the socio-political climate of the region. The effect of desertification in the sahel are very bad because it makes the farmers produce less yield of food to the people in the community, the people and animals dies off because of the lack of food. The effects of drought are being exacerbated by desertification, and the threat of the Sahara desert spreading southwards is considered a major challenge that no single country can tackle it alone. Desertification is a form of land degradation by which fertile land becomes desert. Land resources underpin the livelihoods of billions of people worldwide, and are … Many countries around the world suffer from the problems caused by desertification but it is the Sahel region of Africa where the effects are greatest. only is desertification harmful to the earth and its inhabitants, but it is also expensive – each year, the world loses US$42 billion to desertification and its effects. In China, nearly 20% of land area is desert. In contrast, 43 per cent of the big cities in dryland areas will be hit by desertification. The term desertification refers to the process of degradation of the environment, being the result of either natural conditions (decrease or extreme variability of rainfall) or of adverse human interventions, but leading always to a critical shortage of water for the vegetation. n About 2 billion people are potential victims of the effects of desertification. Destruction of Vegetation; Loss of water and flooding ; The soil begins to become salty and loose to where the crops' roots are exposed and cannot grow. Increased deserts have allowed for a greater amount of loose sand to be available. About 10-20% of the dry land is already degraded with 2.3 million to 4.6 million square miles affected by desertification affecting over 120 million people living in dry areas. n Desertification contributes to internal displacement and international migration of people. 6. Furthermore, land degradation can hasten the effects of drought by reducing the chances of local people to face difficult, dry periods. The question of what the effects of desertification are is a difficult one to answer because it involves complicated interactions between natural and human activity. The fight against desertification is a challenge that affects all the inhabitants of the planet. Desertification has been described as “the greatest environmental challenge of our time” and climate change is making it worse. However, little is known about the effects of desertification on grassland C and N storages in this region. Nowhere in Africa are the effects of desertification felt as in the arid, semi-arid and sub-humid lands. With increasing drylands, there has been 25% increase in annual dust emissions over the past century. Overgrazing is a significant reason for desertification around the world. Dry areas cover about 40% of the Earth's surface and are home to billions of people. 70% of land animals and plant species live in forests. One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. Desertification poses one of the greatest environmental challenges today and constitutes a major barrier to meeting basic human needs in drylands. Effects of Desertification. A field survey was conducted on Horqin sandy grassland, and desertification gradients were established to evaluate the effects of desertification on C and N storages in soil, plant, and litter. The causes of desertification are both natural and man-made. Not only does deforestation threaten species known to us, but also those unknown.
