Global climate change threatens 1.21 million square km of wetlands


Adelaide, 29 July 2023, Saturday

Climate change is beginning to have an adverse effect on wetlands, which are vital for bio-diversity. Wetlands are vital to the world's biodiversity. It makes an invaluable contribution to preventing climate change as it absorbs dangerous gases like carbon. A wetland is an area that is filled with light or shallow water for at least eight months.

Water keeps the soil and surrounding atmosphere moist. According to an information, wetlands are spread over an area of ​​1.21 crore square km of the world. These wetlands benefit the world by $37.8 trillion in deficit production, water quality and carbon sequestration. Wetlands dry naturally and also become dry when water is drained.


According to research, once the amount of oxygen in a wet soil increases, the oxidation of its organic matter also increases and the inorganic minerals decrease. When a wetland dries out, its soil cracks and becomes more acidic. Along with this, the emission of methane also starts to increase. Although the effect of drying in the wetland is not a problem if it is short-term, but if it lasts for 10 years or more, it affects the soil structure and water quality.

There are also different types of soil so its effect can be different. This is known from local research but very little research has been done in regions of the world including South and Central America, Africa, Middle East Asia and Oceania. While wetlands are drying up due to climate change. The information about this was revealed in the research done by Adelaide University.

The central mountainous region in Nepal is considered their home. which is near the Himalayas and the southern Terai plains of Nepal. The Raute people live in temporary houses covered with cloth over wood. However, since they live completely cut off from the rest of the world, it becomes difficult to find their abode. The men of the Raute community are adept at hunting monkeys. Once they have followed a monkey, they do not return without hunting. The Raute people sit around a fire at night in winter. What is new is that they consider it a sin to grow seeds in the soil, so instead of farming, they use the grains found naturally in the forest as food. Every day women and children bring grain bearing plants and extract grains from them. They also eat fruits and vegetables that grow naturally. This nomadic species does no
