Climate change is also leading to an increase in more intense rainfall events. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. Sudden event where large amounts of rock and soil plunge down steep slopes. Annual crops also have to be re-sown each year which means more disturbance of the soils every year. That means the forests and rivers of the DRCthe second largest country in Africa and one of the fastest growing countries in the worldare now on the frontlines. Soil erosion leads to mudslides, which affect the stability and structural integrity of buildings and roadways. What are the bad effects of soil erosion on humans and animals? This can be accomplished by intercropping, which means growing two crops together in the same field, such as planting rows of maize or soybean between rows of oil palm trees. Impacts of Erosion Soil erosion reduces the quantity and the quality of soil ecosystems and arable land (land that can be used to grow crops). The effects of soil erosion go beyond the loss of fertile land. exposure of subsoil, which often has poor physical and chemical properties. Meaning that they are only around for one year rather than a perennial plant that remains over many years. These roots vary in size from large roots for strength to tiny roots for absorption. Soil erosion and sedimentation equally contaminates the water, makes it dirty, and increases its turbidity. What are the cause and effect of erosion?

Were already seeing the risks of soil erosion play out around the world. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. The transition to agriculture from natural vegetation often cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually increase soil erosion beyond the soils ability to maintain itself. And degraded lands are also often less able to hold onto water, which can worsen flooding. In the past 30 years, approximately 3.02 gigatons of carbon has been lost from grassland soils. This leads to plants dying which means that all of the roots disappear and their is nothing to hold the soil in place. Farmers are unable to plant their crops on this land and when this happens, it causes widespread hunger because their is not enough food to go around.

When humans disturb the earth with construction, gardening, logging and mining activities the result is a weakening of the topsoil of the earth, which leads to excessive wearing away and erosion. Another study showed that soil erosion in Sleman, a district located in Java, costs 17% of an average farmers net income per hectare of agricultural land. After the topsoil is eroded because of the loss of vegetation, the next layer that will be eroded is the seed bank within the soil. Trees help hold soil in place, so when they're uprooted, winds and rains push the loose soil and rocks to streams and rivers, again resulting in unwanted sedimentation. In growing crops, humans invest money in purchasing inputs such as seeds, fertilizers, and pesticides among others. The psychology of Reflection Psychology Human self-reflection, What are 10 crazy facts? Animals cause erosion in other ways too. One of the effects of water erosion is that it reduces the compatibility of the soil as it breaks into the soil, thereby making it easy for other forms of erosion to occur in the given area of land.

Some nations are already finding success. Soil erosion is a natural process but one that is being rapidly accelerated due to human activities. Weak root growth or water that evaporates too quickly will result in plants that dont thrive. Company on the podcast, to listen to the episode press play below: Most crops that we produce globally are annuals. Firstly, it makes it difficult for sunlight to penetrate meaning any aquatic plants in the water that need this light for photosynthesis no longer receive it and end up dying. Since everything we eat starts with what grows in the ground, soil erosion's primary impact for people is how it impacts the food chain. This type of erosion depletes organic matter in soil, making it less suitable for planting and harvesting crops or for the natural production of vegetation. These smaller particles of soil created by the tilling process are much lighter and can be eroded by wind or washed away by a heavy rain shower. Another source found it could reach $15,221 per hectare. exposure of subsoil, which often has poor physical and chemical properties. Sedimentation also leads to the excessive growth of algae, as sunlight can get through the sediment. The cost of erosion prevention is far lower than the price of land restoration and rehabilitation, which one source estimated to be around $1,500$2,000 per hectare. When left unchecked, the above mechanism will result in substantial environmental harm. 2010; Brevik 2009a).
