Zabo system

Also called: Ruza · Topic: Land Use, Farming Systems and Cropping Seasons in India · NCERT: Class 9, Ch 2 "Shaping of the Earth's Surface"

Meaning

The Zabo system (also called Ruza) is a traditional farming system of the Chakhesang Nagas of Kikruma village, Phek district, Nagaland. On one hill slope it links a protected forest, rainwater ponds, cattle yards and rice-and-fish paddy fields, so that water and manure flow downhill from one part to the next. It matters because it puts forestry, water harvesting, animal rearing, farming and fish farming into one system that conserves both soil and water. This makes it a model for farming on hills.

Explanation

What the name means

• Zabo means "impounding water". To impound water means to hold it back and store it.
• The whole system is built around catching rainwater high on the slope and using it lower down.
• NCERT teaches it as an example of traditional farmers treating the plant and the soil as one living system. To feed the plant, they fed the soil.

The parts, from hilltop to foot of the slope

Position on the slope	Part	What it does
Hilltop	Protected forest	Holds the soil in place and lets rainwater soak into the ground
Upper slope	Ponds	Collect (harvest) the rainwater
Middle slope	Cattle yards	Animal dung washes down with the water and acts as manure
Foot of the slope	Rice-and-fish paddies	Rice and fish grow together in the same flooded field
Field edges	Earthen bunds (mud walls around fields)	Keep soil and water inside the field

How it works (cause → process → result)

• Step 1: rain is caught.
• Rain falls on the forested hilltop.
• The trees slow the water down, and it soaks in instead of rushing off.

• The water is stored in the ponds below.

• Step 2: water picks up manure.

• Water from the ponds flows down through the cattle yards.

• On the way it picks up dung and urine, which act as farmyard manure.

• Step 3: water feeds the fields.

• The water, now full of nutrients, reaches the paddies.
• It feeds both the rice plants and the fish.

• The earthen bunds hold the water and soil in the field.

• Result: each part helps the next one, and nothing is wasted. The system:

• conserves soil (less soil is washed away from the slope)
• conserves water (rain is stored, not lost as runoff)
• adds manure without chemical fertiliser
• produces two foods, rice and fish, from one field

Conditions it needs

• A hill slope, so that water can flow downhill by gravity from forest to pond to yard to field.
• A protected forest at the top. If the forest is cut, less water soaks in and more soil is washed away.
• Rainfall to fill the ponds.
• Animals (cattle) to supply the manure.
• Community care of the forest, ponds and bunds by the village.

Where it occurs

• India: Kikruma village, Phek district, Nagaland, in north-east India. It is practised by the Chakhesang Nagas.
• Similar hill systems in India that save soil and water (for comparison):

• Terrace farming in Uttarakhand. Steps cut into Himalayan slopes slow down runoff, so less soil is washed away and more water soaks in.

• A system built for a very different landscape (for contrast):

• Kuttanad, Kerala. This is wetland, below-sea-level rice farming beside Vembanad lake. It also combines rice with fishing and duck rearing [2].

• NCERT reference: Class 9, "Shaping of the Earth's Surface" (iest102).

Don't confuse with

• Terrace farming (Uttarakhand): this mainly cuts steps into the slope to slow runoff. Zabo instead links forest, ponds, cattle yards and rice-fish paddies into one chain where water and manure flow downhill.
• Kuttanad below-sea-level farming (Kerala): this is wetland farming. Swamps were drained, and rice is grown about 1–3 m below sea level [2]. Zabo is a hill-slope system in Nagaland.
• Kulagar (Goa): these are homestead gardens of the Konkani people, with trees and crops grown in layers next to the house. Zabo is a slope-wide water-and-manure system, not a house garden.
• Jhum (shifting cultivation) in the north-east: in jhum, forest is cut and burnt, a patch is farmed, and then farmers move on to a new patch. In Zabo, the hilltop forest is protected, and the same fields are farmed again and again.

Prelims Hooks

• Zabo means "impounding water". It is also called Ruza.
• Zabo = Chakhesang Nagas, Kikruma village, Phek district, Nagaland. A common trap is to swap it with Kulagar = Konkani homestead gardens, Goa.
• Order from top to bottom of the slope: protected forest → ponds → cattle yards → rice-and-fish paddies. Earthen bunds run along the field edges.
• Paddy fields in Zabo grow rice and fish together. Do not mix this up with Kuttanad, where ducks are let into the fields after the rice harvest [2].
• Zabo combines five activities: forestry, water harvesting, animal rearing, farming and fish farming. It conserves both soil and water.
• Hill systems vs wetland system: Zabo (Nagaland) and terraces (Uttarakhand) are for hills. Kuttanad (Kerala) is for wetlands below sea level [2].

Mains Points

• A model of integrated, climate-resilient hill farming (GS-I, GS-III).
• On steep north-eastern slopes, fast runoff washes soil away and wastes rain.
• Zabo answers this with a forest to hold soil, ponds to store water and bunds to keep fields intact.

• Rice, fish and cattle together spread risk and give more food from the same land.

• Traditional knowledge backed by science (GS-III, natural farming).

• Zabo feeds the soil with farmyard manure instead of chemical fertiliser, in line with the "plant and soil as one system" idea.
• ICAR documented about 5,000 traditional practices. Over 85% of those it tested were found scientifically valid.

• Systems like Zabo can guide natural farming and soil-health policy.

• Lessons for land use in the north-east (GS-I distribution, GS-III environment).

• Zabo shows a settled, forest-protecting choice compared with jhum, which cuts and burns forest.
• Policy responses: support community protection of hilltop forests, repair ponds and bunds, and record such systems so the knowledge survives. Heritage recognition, as FAO's GIAHS gives to sites like Kuttanad, is one way to do this [3].
