Grade 6 Agriculture Conserving Our Environment – Water Conservation Notes
Conserving Our Environment — Water Conservation
Subject: Agriculture · For learners aged 11 (Kenya)
What is water conservation?
Water conservation means using water carefully so that we do not waste it. In farms and gardens, conserving water helps crops grow well and keeps soil healthy.
Why water conservation is important
- Helps crops grow during dry months (Kenya has long rains Mar–May and short rains Oct–Dec).
- Saves money because farmers spend less on water.
- Prevents soil erosion and keeps soil rich for plants.
- Protects rivers, lakes (like Lake Victoria, the Tana River) and wildlife.
Simple benefits
Healthy crops ✅ More food 🍲 Less fights over water 👥
Farmers in Kenya can plan planting after knowing the rains and using saved water during dry spells.
Practical ways farmers and gardeners save water
- Rainwater harvesting: Collect rain from roofs into tanks for watering crops later.
- Drip irrigation: Small pipes deliver water directly to the plant roots, not the leaves or soil surface.
- Mulching: Cover soil with dry grass, leaves or polythene to keep soil moist longer.
- Planting trees and windbreaks: Trees reduce wind and sun that dry the soil.
- Zai pits and terraces: Small holes or steps on slopes capture water and stop erosion.
- Watering at the right time: Water in the early morning or late evening to reduce evaporation.
- Fix leaks and reuse greywater: Use leftover washing water to water plants (not water used to clean raw meat).
Easy picture: Rainwater harvesting (roof → tank → garden)
Collecting rain is simple and useful in both town and village homes.
Drip irrigation — simple sketch
A pipe with small holes gives water only where roots are. Saves lots of water!
How children can help at home or school
- Turn off taps tightly and tell an adult about leaks.
- Use a bucket when washing vegetables and reuse the water for plants.
- Help spread mulch in the school garden to keep soil moist.
- Make a small rain gauge and observe when rain comes.
Class activity: Make a simple rain gauge
- Find a plastic bottle and cut the top off.
- Turn the top piece upside down and place it as a funnel on the bottle.
- Mark 1 cm lines with a marker on the bottle using a ruler.
- Leave the gauge outside and check after each rain. Record the amount.
This helps you know how much rain fell and when to plant crops.

Glossary (easy words)
- Evaporation: Water turning into vapour and going into the air.
- Greywater: Water from washing dishes or clothes (not toilet water).
- Drip irrigation: Pipes that drip water slowly to plant roots.
- Zai pit: Small holes dug to capture water for planting seeds (used in arid areas).
