Drought Hazard & Management
A slow-onset disaster that requires proactive planning, constant monitoring, and community-wide water conservation efforts.
What is a Drought?
Droughts occur when there has not been enough rainfall and the water levels get low. Unlike a hurricane or a flood, a drought can take weeks or months to develop and may last for years.
In Nevis, droughts can increase the risk of other hazards like wildfire, flash floods, and possible landslides or debris flows when heavy rains finally occur on parched, hardened ground. Droughts can happen anywhere in the Caribbean region.
The primary impact of drought in Nevis is on agriculture and domestic water supplies, requiring carefully managed distribution during dry periods.
Signs & Impacts
Environmental
Changes to the natural water cycle.
- Lowered levels in reservoirs & ponds
- Drying of small streams
- Stress on native vegetation
- Increased wildfire vulnerability
Economic
Financial loss in key production sectors.
- Crop failure and reduced yield
- Livestock loss from dehydration
- Increased food prices
- Loss of income for farmers
Social
Impacts on daily life and public health.
- Mandatory water restrictions
- Poor water-quality risks
- Increased dust & allergies
- Strain on community relations

Domestic Water Conservation
- Don't pour water down the drain — there may be another use for it
- Repair all leaks in faucets and toilets immediately
- Install low-flow showerheads and faucet aerators
- Only run washing machines with full loads
- Listen to and follow the rules from the authorities
- Take short showers, not baths — showers use less water
- Don't let the water run while brushing your teeth
- Re-use 'grey water' for plants where safe
- Plant drought-tolerant and native crop varieties
- Mulch beds to reduce soil evaporation
- Schedule irrigation for early morning or evening
- Build rainwater harvesting and storage capacity
Monitoring Tools
Monthly precipitation vs. historical averages.
Words to Know
The water that exists today is the same water that existed a billion years ago — that's why it's called a limited renewable resource, always travelling through the world's oceans.
Drought Intensity Scale
Understanding the colour-coded alerts used in our monitoring systems.
Level 1: Dry
Abnormally dry conditions. Short-term dryness slowing planting. Voluntary water conservation requested.
Level 2: Severe
Severe drought impacts. Crop and pasture losses likely. Water shortages common; restrictions mandatory.
Level 3: Critical
Extreme / exceptional drought. Widespread crop and pasture losses. Emergency water distribution active.
