Cause and Effect of Flooding


Climate crises have occurred in many countries in 2020.  Heavy rains have caused endless floods and made people homeless.  Due to climate change, global warming, and heavy rains, China, Japan, and Indonesia have caused serious floods, severe soil and rock flow, forced relocation of people from their homes and their lives have been seriously threatened.  Extreme climates are happening all over the world.  Everyone should face up to the crisis, and governments of all countries should take measures to deal with the possible impact of climate change.

China has suffered from floods since early June 2020, the most intense rainstorm over the past 50 years.  At least 219 people were found dead or missing.  433 rivers rose to a dangerous level, nearly 40 million people from 27 provinces included Hunan, Anhui, Hubei and Jiangxi have suffered from record-setting floods.  As a result, 3.53 million hectares (2 Beijing's area) of farmland flattened 28,000.  The economic loss exceeded 82.2 billion yuan.  Severe floods and landslides affect most of the rural areas in the suburbs, crop harvests are affected, and the prices of vegetables and pork fluctuate.  The Chinese government's approach is to protect important cities without endangering personal safety.  Most of the flood impacts are villages with relatively small economic output. Although some factories have shut down and equipment is damaged, it is already a blessing for the country.  Future repairs may need to pay attention to the safety of water conservancy facilities to reduce the impact of natural disasters in the future, as well as food shortages caused by extreme weather floods or droughts.

Typhoons, storms, and heavy flooding have hit Japan hard especially Kumamoto.  The disaster was so severe that some people were found dead and millions of people moved away from their homes.  The heavy rain affected the logistics and manufacturing supply chain, the suspension affect may not be optimistic in Japan's economy.

Flash floods occurred throughout the Indonesia capital of Jakarta lead the river to overflow, and landslides flow.  Uncontrolled population growth in urban areas, poor land-use planning, and the lack of understanding among city residents and government about floods and its disaster risk exacerbate the impact.  Heavy rain and large-scale deforestation in the upper reaches to plant oil palm trees will cause flooding.

Flash floods occurred throughout the Indonesian capital Jakarta, causing rivers to overflow and landslides. Uncontrolled population growth in urban areas and improper planning of urban over-development land use.  Large-scale deforestation in the upper reaches and excessive extraction of groundwater has caused the soil to dry out.  The lack of understanding of floods and disaster risks by urban residents and governments has exacerbated this impact.  Research on stratum subsidence warns that Jakarta, Indonesia may become the fastest sinking city in the world.  In addition to development, every country should also consider water and soil conservation in order to avoid big losses.

Extreme climates are taking place in various countries, the reconstruction and development expenditure may have a certain degree of pressure on all countries’ finances.  Therefore, countries with extreme climates must focus on water conservancy projects in future economic construction and development to prevent floods.   It is everyone’s duty to be involved in environmental protection the earth makes our world better.
