Farmers must prevent accelerated erosion on their farms. Erosion on agricultural land can cause loss of upper soil layers.Farmers must prevent accelerated erosion on their farms. Erosion on agricultural land can cause loss of upper soil layers. This is because erosion can result in the loss of nutrients needed plants to grow and develop optimally. Erosion on agricultural land can cause loss of upper soil layers. If this happens, it will be very detrimental to farmers and planters. The loss of topsoil can cause a decrease in the levels of organic matter, increase in soil compaction, decrease in soil aggregate stability, increase in aluminum saturation and decrease in soil exchange capacity.
Erosion events that are more often can reduce levels of organic matter and nutrients in the soil. This can reduce soil quality. On ultimately reducing soil productivity. Farmers must maintain soil productivity. This is so that farmers get production of agricultural production to remain highly engaged. And this means that farmers have to pay higher costs to add soil nutrients.
Climate change has an impact on increasing air temperature and sea level, seawater intrusion which increases the salinity of the land agriculture, changes in rainfall patterns, increased extreme events of El Nino and La Nina. All of these are factors that can affect agricultural production. Agriculture is a sector that is vulnerable to climate change.
Climate Change and Erosion on Agricultural Land.
Erosion on agricultural land transports agricultural land materials. Water and wind movements cause erosion on agricultural land. High rainfall causes erosion on agricultural land. One of the effects of climate change is increasing rainfall. Climate change that increases rainfall is what can cause erosion.
Erosion not only decreases the physical and chemical quality of the soil. It also decreases water quality. Therefore, this erosion is a serious problem. Erosion on agricultural land can lead to declining productivity and carrying capacity of land for agricultural production and the environment. This is because in the erosion process there is the transport of nutrient-rich topsoil. Erosion that runs intensively on the ground can cause transport of clay and humus complexes and other soil particles. This soil surface is rich in nutrients needed by plants.
Erosion can occur very slowly, or it can be very fast. The acceleration of erosion depends on the landscape, the slope of the land, the nature of the sensitivity of the soil and the conditions of the rain. For example, erosion on sloping agricultural land will be faster than on sloping land. While the erosion process can occur naturally or be accelerated due to human activities.
Climate Change and Surface Flow
Climate change can cause changes in rainfall patterns. Furthermore, changes in rainfall patterns have resulted in increased rainfall intensity. The high intensity of rain can lead to increased surface flow and erosion.
Surface flow comes from excess infiltration (infiltration excess overland flow) that occurs when the intensity of the rain exceeds the infiltration rate. To know the nature of the surface flow, we need to understand the factors that influence it. Factors that influence the nature of surface flow include:
(a) rainfall: number, intensity, and distribution;
(c) soil: type, type of substrate and topography (sandy soil will have a lower surface flow rate than soil with soil);
(d) the area of flow and the length of the slope (the surface flow rate will be higher with the length of the slope);
(e) the existence, height, and shape of the canopy and the density of plants/plants covering land;
and (f) land management systems.
