The Sinking City: Bangkok

Catagory : News  Date : 18 2022   Time : 13:39:06

While some may be skeptical of climate change, the effects are already being felt—and are undeniable—in Bangkok. The rainy season used to be as dependable as Thailand's abundant rice production, raining down on Thai fields like clockwork from mid-April until October, when the weather abruptly changes and the country becomes bone-dry for six months. Rain has dropped unpredictably in recent years, creating flooding, destroying farms, destroying livelihoods, and harming millions of people.

Meanwhile, temperatures are rising, and Bangkok has been added to the list of Southeast Asia's most vulnerable cities due to growing urbanization and severe land subsidence. However, recent events have drawn attention to the urgency of the problems, prompting some action.

Following a severe flood earlier this decade, Bangkok launched a slew of government-backed measures to address environmental challenges, enlisting a diverse group of international partners. Bangkok has joined the Rockefeller Foundation's 100 Resilient Communities project, which helps cities throughout the world prepare for the various ecological and economic problems of the twenty-first century.

Bangkok may appear to be an unexpected addition to the list of climate change disasters. The impact of increasing sea levels and surging tides on coastal people and vulnerable low-lying islands are frequently covered in the media.

Thailand's capital is sinking by up to 10 millimeters per year, posing a threat to the city's population of roughly ten million people. The Chao Phraya River has been prone to flooding regularly, most recently in 2011, when heavy rains flooded rivers in the north, overflowing levies and engulfing Bangkok for months. Over 800 individuals were killed in the 2011 flood, which cost an estimated $50 billion and affected 13 million people. Thailand was listed among the top ten countries in the world most affected by climate change in the 2017 Global Climate Risk Index.

Bangkok's very life is in jeopardy as temperatures continue to climb year after year, adding to rising water levels. Due to heavy rainfall and changing weather patterns, the World Bank predicts that 40 percent of Bangkok will be flooded by 2030.

One instance study, from the non-governmental group Germanwatch's 2017 Global Climate Risk Index, looked at Bangkok on the assumption of a four-degree temperature increase in the future. The city would be severely flooded in this scenario, with a 40 percent inundation during a high rainfall event and a 15-centimeter (6 in) sea-level rise (SLR) by 2030. Further investigation revealed 70% inundation and a projected 88-centimeter (35-inch) SLR by 2080.

Flooding fears along the Chao Phraya River system are exacerbated by the rising seas predicted as a result of global warming. Thailand's main water system irrigates much of the country's agriculture and feeds nearly half of the Thai population, including the urban expansion from Bangkok to Samut Prakan, which was once a delta region prone to flooding and siltation.

The temple was once on land, but erosion has reduced it to a sliver of an island in a rushing inland sea. On the sand, the remains of forts that were frequently shifted as riverbanks eroded over time may be seen. According to Greenpeace, the waters of the Gulf of Thailand are rising at a rate of four millimeters (0.2 in) each year, significantly faster than the global average.

Paving over canals, ponds, and greenery with concrete further exacerbates heat island effects, an issue connected to climate change in which an urban area is significantly warmer than surrounding rural areas as a result of human activity. The contrast is usually more noticeable at night and can be ascribed to the lack of shade, greenery, and cooling water, as well as concrete and other materials that store and subsequently radiate heat.

Then there's the seriousness of ground subsidence in an urban environment where concrete continues to spread and gobble up what little flora there is. According to the Siemens Green Metropolis Index, Bangkok is Asia's least green city, with only 3.3 square meters (36 square feet) of green space per person. Singapore, on the other hand, provides 66 square meters and even New York City provides 23.1 square meters (249 sq ft).

Because so much of the city has been paved over, the permeable area has been substantially reduced, hastening the sinking; Bangkok is said to be sinking 10 times faster than the sea level is rising. Much of the city is now only half a meter (1.6 ft) above sea level, and several areas are already below it, as the metropolitan area continues to grow and engulf a population of more than 15 million people.

More than just hope is required in Bangkok. We must put all the plans into action starting from right now.


What is LED Farm doing on its part?

LED Farm employs a sustainable and environmentally friendly hydroponic-vertical farming method. Traditional farming methods are significantly less sustainable than hydroponic gardening. It conserves water, space, and energy, making it more environmentally friendly. With climate change causing unpredictable weather patterns in Bangkok and elsewhere, any improvements we can do to reduce our influence on the environment are vital. Here are a few ways that hydroponic farming is more environmentally friendly.

It Saves Water

To begin with, hydroponic farming can save up to 98 percent on water. While farmers introduce water into the system, it is recycled several times, so extra water is rarely required once the process is up and running. Agriculture uses 70% of the world's freshwater, therefore a 98 percent reduction in usage would result in huge water savings.

It Saves Land

Vertical farms use 99 percent less land than traditional soil-based farms, saving a substantial amount of area. This smaller footprint is significant because it allows us to fit commercial hydroponic farms into urban locations where space is limited, reducing pollution from local transportation. Because hydroponics does not require fertile ground, we can now grow healthy food in regions where farming was previously impossible due to infertile soil and harsh weather.

It Saves Energy

Agriculture consumes around 21% of the energy used in food production. The food supply chain consumes almost 13% of all energy in the United States. Any reduction in this would have a huge impact on Thailand's energy use. Increasing sustainability by lowering transportation expenses by growing food locally reduces the amount of energy used considerably.
