The Worlds Soil is Drying Out
One of the main problems in today’s world news is the dry weather conditions that is making the soil dry out very quick. It has been said that dry lands will increase to 23% by the end of this century. Many plants, animals and humans are suffering from this dramatic climate change, and dry lands are said to become drier. Dry land ecosystems are significant for humanity and the environment since they cover around 41% of the Earth’s surface. These dry lands also provide a group of unique species that one may not find in other parts of the world, which in turn plays a significant role in the global carbon cycle.
Many researchers had carried out studies on soil microbes globally, and made interesting discoveries. They carried out two studies that looked at the effect of dry land on soil microbial diversity. The first study observed 80 dry land locations on all continents, and found that soil bacteria, fungal and abundance had condensed at the dry lands increasingly become drier. The second study investigated the link between microbial diversity and plant productivity and soil fertility. They observed dry lands in all areas worldwide and then compared their results in areas such as forests, grasslands, bogs and croplands in Scotland. The results indicated that there is a relationship between higher microbial diversity and higher plant productivity and soil fertility in these areas worldwide. The same relationship on microbial diversity was found in the Scotland areas.
As a result, the combination of human actions and the drastic climate change will affect the ecosystem, which in turn will affect the food cycle worldwide. The dry land areas are most likely to be found in developing countries. These countries will most likely face problems in the long-term, which includes less food security and sustainability in the environment and removing carbon.
