Therefore, this place has become learning resources in terms of eco-friendly development and is

an important ozone source near the center of the metropolis.

*Remarks: Khung means Bend of watercourse

2. Classification of the best practice / technology

Due to the fact that the area of this technology was previously the ecosystem of brackish-
water forests or the convergence area of seawater (saline water) and fresh water. Salinity of the

brackish water is between 0.5 – 30 ppt (part per thousand) or of the amount of salt sodium between
0.05 – 3 %. In recent years, there have been changes at Khung Bang Krachao (Bang Krachao river

bend). What can be seen obviously is the fact that the area has been waterlogged by sea water

longer than before. Previously, waterlogging lasted only 3-4 months, but currently, it lasts more
than 6 months. When there is a longer period of waterlogging of the seawater, fruit trees which

farmers plant in the garden bed gradually stand and die such as the Nam Dock Mai mango,
Syzygium, Garcinia, including many kind of aquatic animals such as Freshwater fish which cannot

live in saline water and dies in succession. When fish dies, mosquito larva are not eaten. As a

result, the quantity of mosquito larva increases. The garden bed is transformed into
accommodation. Watercourses are filled, resulting in no circulation of water resources and waste

water. There is more waste in the area. Also due to more expansion of the community, green areas
in the part of the private property about 90% have been changed rapidly in terms of social and

economic conditions.

3. Technical specifications, implementation activities

1. Suan Pa Ked Nom Klao (Ked Nom Klao Forest Park) is considered to be one of the

target areas of conserving green areas of the Garden amid Metropolis project according to Royal

Initiative of His Majesty King Bhumibol Adulyadej (King Rama 9) who wanted to conserve the
nature at the area of Khung Bang Krachao for all 6 sub-districts, namely Tambon Bang Nampueng,

Tambon Bangkohbua, Tambon Song Kanong, Tambon Bang Krachao, Tambon Bangkasob and
Tambon Bang Yo of Phra Pradaeng District of Samut Prakan Province or so-called pork stomach.

The objective is to build and support it to be an eco-tourism destinations in the form of urban
community forests and to function as lungs for Bangkokians.
