Perhaps some of you don't know about this hole. It' a hole called Biopore that can absorb water to prevent floods. The biopore method was first devised in 1976 by Ir. Kamir Raziudin Brata, MSc, a researcher and lecturer at the Soil and Natural Resources Science Department in the Bogor Institute of Agriculture (Indonesia).By making this Biopore hole:
1. You can prevent floods
2. You can improve the soil's water absorpsion
3. You can change the organic wastes into compost and by that you can also reduce the greenhouse gasses (CO2 and methane).
4. You can help the land faunas and plant roots' activities to make another holes which then the holes can also improve the soil's water abrorpsion.5. You will improve the fertility of your soil.
How to Make Biopore??
If you want to know how to make this infiltration hole, you can read the steps below.
1. Dig a vertical cylindrical hole into the soil that is 10 cm in diameter and about 50-100 cm deep. Such holes can be dug in house yards, gutters, along terrace walls, open grassy fields and any place where rainwater collects.
2. (This step is optional. If you want to keep the intact, you have to do this step) Keep the rim of the hole intact by cementing it with a mixture that is 2-3 cm wide and 10 cm deep around the opening to keep it from eroding. Another alternative is to insert a 12-cm pvc pipe inside the upper part of the hole.
3. Shove in organic waste – kitchen scraps, plant remnants, dried leaves, cut grass and other vegetable matter. Such organic waste will attract small creatures such as worms and termites to enter the hole and create additional bioporic tunnels.
4. Don't forget to keep putting more organic waste into the hole since the composting process will gradually decrease the amount of waste already inside the hole.
After the hole’s maximum capacity has been reached, the compost inside can be taken out and used as fertilizer. The compost can be harvested over a certain period of time and used as organic fertilizer for plants.
Let's make this biopore!
Well, I have already :D
how effective this method will be on flood prevention?
ReplyDeleteI don't know exactly how effective this method is. There's a research about this and stated this method's quite effective (but depends on soil type, topography, intensity of water, etc). Proved in some regions in my country, this method can reduces the potential of flooding up to 40% and also effectively reduce the waste up to 30%.
