Why Does Jakarta Flood So Easily? Crash Course Geography #24

Spread The Viralist



Today we’re going to talk about how and why floods happen both in spite of, and because of, us. Specifically, we’ll take a closer look at the island of Java, and its largest city, Jakarta, and explain the factors that lead to serious flooding almost annually. We’ll also show you how mangroves can help protect us from flooding, and how wetlands along floodplains act like the kidneys of the Earth filtering out impurities and pollutants.

  1. Thanks for the insight??
    It helped me a lot to understand why we, in Jakarta metropolitan area, often experience flash flooding annually every time the rainy season occurs

  2. wow, that's a quick explanation. but as far as I know, Java is an island inhabited by 56.10% of the total population in Indonesia today (Population Census: Bureau of Statistics 2020). and seems to continue to grow from year to year, which means that the existing land area can get smaller due to the emergence of new residences, new public facilities etc, etc.

    guess what the picture will look like in the next few years. with very high pressure loads, plus flooding, plus concrete buildings, plus overflowing drainage, plus unstable natural conditions, and other pluses that aggravate the situation. god bless us ??

  3. I realize how the goverment messed up when this area of the city in the 1980s are wetlands. But now it has a huge ass mall, a building, lots of stores, housing area, a toll route, and an LRT. And every year it always flood there

  4. I'm living in rural area of Java, and well some rapid development are somewhat ridiculous if viewed from environmental pov. The historical rainforest has become very limited in small national parks, swapped by many agricultural fields, and nowadays those agricultural fields once again swapped by human buildings in the name of economic development, from factory, housing, cafe, or even public facilities like airport. Environmental consideration haven't become quite priority in government, business, even common people mind when doing something about those economic things.

  5. Living near an area with lots of abandoned mines…thanks for your explanation of the associated problems! There may have been gold in them thar hills at one time, but not now! Pb, As, Zn etc. Aaacckkk!
