Introduction The word disaster is derived from
Middle French désastre
Old Italian disastro,
which in turn comes from the Greek
pejorative
prefix δυσ-, (dus-) "bad" + ἀστήρ (aster),
"star“.
The root of the
word disaster ("bad star" in Greek) comes
from an astrological theme in which the
ancients used to refer to the destruction
or deconstruction of a star as a disaster.

Core concept :Droughts :
Drought is unusual dryness of soil, resulting in crop failure and shortage of water for other uses, caused by significantly lower rainfall than average over a prolonged period.
Hot dry winds, high temperatures and consequent evaporation of moisture from the ground can contribute to conditions of drought.
Droughts :Drought is an extended period of months
or years when a region notes a deficiency in its water supply whether surface or underground water.
Generally, this occurs when a region receives consistently below average precipitation.
It can have a substantial impact on the ecosystem and agriculture of the affected region.
Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy
Types of drought
Meteorological drought :related to rainfall amounts.
Hydrological drought :determined by water levels in reservoirs.
Agricultural drought: related to the availability of water for crops .

Agro-climatic zones of Maharashtra
Facts :132 districts declared under drought terror .
There are 6,201 villages where the kharif yield
is below 50 paise and 1,552 villages where the
rabi yield was below 50 paise.

Impacts of Drought
The impacts of drought can be categorized
as economic, environmental, or social
A. Economic Impacts
B. Environmental Impacts
C. Social Impacts
ECONOMIC•Costs and losses to agricultural production•Costs and losses of livestock producer•Losses from timber production•Unemployement•Financial strain on institution
ENVIRONMENT
• Damage to animal species
• Hydrological effects• Damage to plant
community• Increase in air
pollutants• Loss of wet lands• Lower water levels in
reservoirs, lakes, and ponds
• Restrains on water use.
SOCIAL•Health•Mentral stress in population•Reduction in nutrition•Loss of security•Anxiety•Depression
Drought management:3 major components of drought management :
1. Monitoring and early monitoring
2. Risk and impact management
3. Mitigation and response.
