Subak Abian: The Dryland Irrigation Groups of Bali
Subak abian are the traditional dryland irrigation groups of Bali, which manage water for gardens and dry fields rather than for rice paddies. In short, these are the communal farmer groups that share water on the island’s upland and dry-ground plots, and they follow the same cooperative principles as the better known rice subak but serve a different set of crops. The sections below explain how they differ from the wet-rice groups, which crops they grow, how members share water and set the cropping calendar, the ceremonies tied to the group, and where a visitor may see dryland gardens in Bali.
How subak abian differ from the wet-rice groups
Bali’s best known irrigation system is the subak that serves the wet-rice terraces, where water is channelled across flooded paddies and the rhythm of planting follows the flow. The dryland groups work on a different basis. Their fields are not flooded, and the crops do not need standing water. Instead, the group manages the supply of water that reaches the gardens, which tends to be drawn from rain, springs and channels from higher ground.
The difference shapes the landscape and the daily life of the members. Wet-rice terraces create a stepped, green mosaic across the hills. Dryland gardens look more varied, with plots of different sizes and shapes, mixed planting and a more irregular pattern of trees and shrubs.
The crops grown on dryland plots
Dryland subak members grow vegetables, fruit trees, spices and other crops that suit well-drained soil. Chillies, shallots, cassava, corn and a range of leafy vegetables are common on the plots, and the fruit trees and spices add height and variety to the planting. The mix varies from village to village, depending on the soil, the altitude and the market.
Crops are chosen for both food and sale. Many families keep a plot for their own table and sell the surplus at local markets. Planning the planting so that the harvests come at different times helps spread the income across the year, and the group’s cropping calendar is designed with this in mind.
How members share water and set the calendar
Water is shared by the members under agreed rules. The group decides when water is released into the channels, how long each plot may take its share and what happens in dry periods. These arrangements are usually worked out at regular meetings, and they reflect the needs of the whole community rather than the wishes of a single farmer.
The cropping calendar follows the water and the seasons. Planting is timed to the arrival of the rains, and harvests are arranged so that the demand on the shared supply is spread out. Members who break the agreed timing can affect others, so the group relies on trust and on the authority of its leaders to keep the system working.
Ceremonies tied to the group
Like the wet-rice subak, dryland groups are linked to temples and ceremonies. The temple of the group is a place where offerings are made at set times, and the ceremonies mark the planting, the growing season and the harvest. These occasions bring members together and reinforce their shared responsibility for the water and the land.
Visitors who see a ceremony should watch respectfully. Offerings are carried in procession, and music and prayer mark the event. Dress modestly, avoid walking over the offerings and ask before photographing people at prayer.
Temples where the water enters the system
Each subak has its own temple. In the wet-rice system the temples and stone altars are placed at the intake weirs, the points where water enters the channels, so the water is honoured at the point where it first enters the system, before it is shared out. The same idea of respect for where the water begins runs through the whole system, and the dryland groups share its ceremonial framework even though their water comes from rain, springs and channels rather than from a single flooded network.
The temple ceremonies follow the agricultural year. Offerings are made at the start of planting, through the growing season and after the harvest, and each occasion brings the members together to confirm their shared responsibility for the land and the water.
The gratitude ceremony at Jatiluwih
The temple of Pura Ulunsuwi in Jatiluwih village, in the Tabanan countryside, holds a ceremony called Sarin Taun, an expression of gratitude for the harvest. It takes place once every three years, and it is preceded by a sequence of smaller and larger temple festivals that build towards the main day. Members of the subak carry offerings as part of the procession.
Visitors who are in the area during a festival season should check locally before travelling, since the dates are set by the temple and the village and can shift from year to year.
A farmer’s ritual year
Members carry out a long run of ritual duties through each growing season, from the first water into the fields to the offering after the harvest. The duties differ between groups and villages, but they share one purpose, which is to keep the members aware that the water belongs to all of them and that each plot depends on the others further along the channel.
Those duties help explain why the cropping calendar is so carefully kept. A missed ritual or a planting that runs out of step can disturb the timing for the whole group, so the members usually discuss changes together before they make them.
What to look for on a walk through the gardens
- Mixed plots, with vegetables, spices and fruit trees growing side by side rather than a single crop across a wide field.
- Trees and shrubs at the edges of the plots, which give shade and break the wind on open slopes.
- Small irrigation channels and gates that carry water from the main supply to individual plots.
- Village temples and shrines close to the fields, which mark the group’s place in the landscape.
Where a visitor may see dryland gardens
Dryland gardens are found in several upland and dry-ground areas of Bali, and they are frequently seen along village roads and on the slopes beyond the rice terraces. The Tabanan countryside on the west of the island is one good area for seeing a mix of irrigation systems, and the rice terraces around the central highlands show the contrast with the wet-rice subak.
The best way to see the gardens is to walk the lanes at the edge of the villages in the morning, when farmers are working their plots. Ask before entering any private garden, and buy produce from local stalls rather than picking from the plots.
Understanding the system from the ground
The dryland groups are a reminder that Balinese agriculture is not one system but many. Each group adapts its rules and its calendar to its own land, and the members learn from one another as much as from their leaders. A visitor who sees the gardens and asks questions will begin to understand that the water management of the island rests on a web of local agreements.
The groups also show how traditional organisation can respond to change. Modern markets, new crops and changing rainfall all press on the system, and the members adjust their practice while keeping the cooperative principles that hold the group together.
How to behave respectfully in the fields
Walk on the paths and keep to the edges of plots. Close gates behind you, avoid touching irrigation channels and do not pick crops without permission. Dress modestly, carry water and a hat, and be prepared for the sun on open slopes. A friendly greeting in Indonesian or Balinese is welcomed, and a short conversation with a farmer tends to be the most rewarding part of the walk.
Connecting dryland subak with the rest of Tabanan
The Tabanan guide sets out the rice country and the west coast of the regency, and it is a good starting point for planning a day among the fields. The Subak Museum in Tabanan explains the wider system of Bali’s irrigation groups and gives useful background for understanding the dryland variants. For the wet-rice side of the story, the Subak irrigation system page covers the terraces and their water temples, and the Balinese culture guide places the groups within the island’s ceremonial life.
Who will get the most from a visit
The dryland groups suit visitors who want to understand how Bali’s farmers manage water beyond the famous terraces, and anyone interested in cooperative agriculture and ritual. They make a good read before a walk through the Tabanan countryside. They are less suited to travellers looking for a ready-made tour of farm operations, because the groups are local institutions rather than visitor attractions.
Summary for the visit
Subak abian are Bali’s dryland irrigation groups. They manage shared water for gardens of vegetables, fruit and spices, follow a cropping calendar agreed by their members and keep ceremonies tied to the group’s temple. They differ from the wet-rice subak in water use and landscape, and they are best seen by walking the village lanes of the upland and dry areas, respectfully and with questions asked politely.
