Rice Bowl of Bali
With the rich and fertile volcanic soils and plentiful water, rice cultivation in Bali is of key agricultural importance and is well known worldwide for its unique and efficient use of irrigation water in the many terraced paddy fields. One of the fundamental backbones of this rice production is the subak. Subak is the name of water management or irrigation system for paddy fields in Bali. For Balinese, irrigation is not simply providing water for the rice plants, but water is used to construct a complex, artificial ecosystem. Paddy fields in Bali are built around water temples and the allocation of water is supervised by a priest.
The subak comprises many individual parts:
With the growth of tourism and urbanisation in Bali the subak is coming under increasing pressure. with farmers tempted to sell their rice fields and move into other more lucrative jobs such as construction or tourism. The highly productive arable land is unfortunately getting lost at an accelerated rate due to excessive building and tourist activities.

Supervolcanic Lake
Lake Toba is the largest lake in South east Asia and is also the largest volcanic lake in the world, 100km long, 30km wide and 505 m at its deepest point. It is located in the northern part of Sumatra, Indonesia and was formed after a supervolcanic eruption 69,000 to 77,000 years ago. This eruption is believed to have been the largest eruption anywhere on Earth in the last 25 million years. According to some anthropologists and archeologists it had global consequences, killing most humans and creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today.
