Our experience, plantation, water management system, and prospective projects

Our Water Management System

Due to the existence of the mountainous, highland region (i.e. Bukit Barisan) in western Sumatra, when there is precipitation the water most likely flows towards the eastern part of the island where our project site is located. This is because of the low and flat characteristics of our lands and partly resulted from the way our earth rotates. Such conditions make our plantation a highly potential area to capture and store freshwater and as we know, freshwater from groundwater and natural precipitation is very essential for agriculture, human life, and the industry.

So, basically, that is what we do using our water management technology: capturing the freshwater and keeping it as our resource, instead of simply letting it leave back to the ocean. The basis of our comprehensive plantation system largely lies on this inventive water management system. As seen in the Water Management Trinity diagram, the system comprises of three main components (i.e. the Canals, the Dams and Water Gates, and the Dikes) and it supports three aspects of sustainability including the environmental, economic, and social aspects.

Environmentally, our comprehensive water management system has been scientifically evident to enable our lands to be fire proof. The integrated mechanism of our canals, water gates, and dikes ensures that the naturally saturated soil in our lands receive the exact amount of water needed to keep the soil moisturized. It also slows down land subsidence and abrasion as the dikes and water gates do not allow the natural precipitation to simply erode the top soil to the sea.

Economically, our comprehensive water management system largely contributes in ensuring the constant provision of freshwater supply for all purposes. In this era where freshwater scarcity keep increasing, its availability holds a more pivotal role in any kind of economic activity. By providing the massive amount of it within our plantation, we safeguard all economic activities evolving in our vicinity, including the ones related to the agricultural development, industrial operation, and human survival.

Other than that, our system is proven to support the conversion of suboptimal land into productive land in the most sustainable manner. Based on our experience, cultivating the empty, non-arable land located in a distinctive geographical area like the one we have, may be more economically viable in a long run compared to expanding arable land in a habitable and/or densely-populated area. The process may require higher initial investments such as initial treatment to make the land less acidic and the basic infrastructure to make the comprehensive system works. However, when one has successfully done it, it can produce a relatively better quality of arable land and requires less capital maintenance expenditure in the long run

Consequently, by incorporating our successful system into the development of local economy, we have managed to create direct and indirect employment opportunities and contributed to the decrement of local and national unemployment rates.

This point reflects the social commitment of our systemic trinity as well. Together with it, our system also helps ensuring that the local people are food sufficient and safe from the adverse effects of extreme climate events such as the prolonged drought and extreme flooding caused by prolonged rainy season.

The Canals

Our man-made canals consist of the primary, secondary, and tertiary canals that adds up to more than 10,000 km in total. It made available 10,357 m3 volume of freshwater in our site all year round. These canals hold four main functions:
1) water retention/reservoir;
2) fire mitigation;
3) freshwater supply for all purposes (i.e. human life, agriculture, industry); and
4) transportation of people and the harvested crops.

Prior to the introduction of our canal system, the traditional, smallholder farmers merely used the canals to drain the water out and they relied highly on the tidal condition (high tide, low tide) in utilizing the canals for transportation purposes. Meanwhile, our comprehensive system enables the canals to reserve freshwater for multiple purposes and the canals are not dependent on the tidal condition. The canals used customizable design and are dredged approximately once every 18 months to enable consistent discharge of water to be maintained.

The Dams and Water Gates

Our dams and water gates are the only imported components of the system infrastructure and they are extremely important for the integrity of the whole system. Their integral role is basically to act as the water level regulator as well as the locus of control of water retention. The suitably placed gates control water distribution to individual areas and ensure adequate supply of water at certain levels is consistently maintained. Traditionally, the gates are not typically used by the farmers and their utilization in our comprehensive system is proven to be able to mitigate the extreme climate phenomena such as the prolonged drought and the natural flood that is generated by the unexpected sea level rise.

The Dikes

Before our system was introduced to the non-arable lands, the dikes are not systematically maintained due to the constraining resources. Their design was also not based on scrupulous formula. Once our comprehensive system is introduced, the dikes are maintained periodically with differing frequencies which depend on the age of the dikes. The design of our dikes follow specific formulation which enables them to withstand the pressure better and last much longer compared to the traditional ones that made of local materials which are easily degraded by natural causes. Our dikes are built all around the area so the seawater will not sip through and they hold important containment function to separate the seawater and freshwater and to effectively manage the water level
