Disaster Profile of Karnataka
The State of Karnataka spans several bio-geographic, hydro-meteorological and agro-climatic zones. Karnataka is vulnerable to multiple natural hazards such as drought, flood, hailstrom, etc. The Harzard, Risk, Vulnerablity of each district is amplified in the District Disaster Management Plan under Disaster Management Plans tab. Brief disaster profile of State is as follows:
1. Drought
Drought is a temporary aberration, unlike aridity or even seasonal aridity, which is a permanent feature of climate. Drought in contrast is a recurrent, yet sporadic feature of climate, known to occur under all climatic regimes and is usually characterized by variability in terms of its spatial expanse, intensity and duration. Condition of drought appear primarily, though not solely, on account of substantial rainfall deviation from the normal and/or the skewed nature of the spatial/temporal distribution to a degree that inflicts an adverse impact on crops over an agricultural season or successive seasons.
Drought differs from other natural hazards since it has a slow onset, evolves over months or even years, affects a large spatial extent but causes little structural (infrastructure) damage. The onset and end and severity are often difficult to gauge. The impact of drought span economic, environmental and social sectors.
The National Commission on Agriculture in India has classified drought into three types: meteorological, agricultural and hydrological. Meteorological drought is defined as a situation when there is significant decrease from normal precipitation over an area (i.e., more than 10%). Hydrological drought results from prolonged meteorological drought resulting in depletion of surface and sub-surface water resources. Agriculture drought is a situation when soil moisture and rainfall are inadequate to support healthy crop growth. Drought is also classified on the basis of time of onset as early season, mid-season and late season.
Karnataka is one of the Southern States in India covering an area of 190.50 lakh hectares with varied topology and is located within 11.5 degree North and 18.5 degree North latitudes and 74 degree East and 78.5 degree east longitude. Karnataka is beset with frequent droughts. The droughts have been very frequent phenomena in the past two decades. In the past 15 years, 13 years have been drought year of varied intensity in Karnataka as shown in the table below.

Drought Monitoring in Karnataka Karnataka State has the distinction of being first in the country to establish a Drought Monitoring Cell (DMC) in 1988 as an institutional mechanism affiliated to Department of Revenue (Disaster Management), Govt. of Karnataka.
Subsequently in 2007, the DMC was renamed as Karnataka State Natural Disaster Monitoring Centre (KSNDMC) and the activities were broadened to also include monitoring of other natural disasters viz., Floods, Hailstorms, Gale-Winds, Storm-surges, Earthquakes, Landslides, and Tsunamis etc. KSNDMC has established Master Control Facilities in its own land of 10 acres for which activities are taken up in providing Alerts/Early Warnings/Forecast/Advisories to the farmers, fishermen, Governance and others in the State along with information dissemination for real time data towards providing Near Real Time Alerts/Early Warning/Advisories to the Community.
KSNDMC collects real time rainfall data upto Gram Panchayath level. KSNDMC analysis the rainfall pattern and sowing status every fortnightly and shares the same with Agriculture, Horticulture and Animal Husbandry Departments.
For more information on KSNDMC please visit www.ksndmc.org
The drought situation is reviewed regularly by the Principal Secretary, Agriculture Department through video conference with the District/Taluk field officers. The “State Level Committee to Review the Season, Crop Condition and Drought Relief Measures” under the Chairmanship of Additional Chief Secretary and Development Commissioner reviewed the situation. The Additional Chief secretary cum Development and the Principal Secretary (Disaster Management) Revenue Department reviewed the situation with the District Deputy Commissioners through video conferencing. The Cabinet Sub-Committee analysis the inputs given by KSNDMC and reports of aforementioned review and shall recommend Cabinet to declared drought as per the Drought Manual of Govt. of India. State Cabinet reviews the input given by Cabinet Sub-Committee and declares drought. Brief Agriculture Profile of Karnataka Karnataka State has 121.61 lakh hectares cultivable area out of its' total geographical area of 190.50 lakh hectares, accounting for 64 %. Arid regions which receive less than 750 mm of rainfall are drought prone and constitute more than two-third of the geographical area. Average gross cultivated area is 124.22 lakh hectares (average of 2010-11 to 2014-15), out of which 40.92 lakh hectares (33%) is irrigated and the rest 83.30 lakh hectares is rainfed (67%). About 62% of the area is under five Dry Zones out of the total ten agro-climatic zones in the State. Average area under agricultural crops is about 105.39 lakh hectares spread over three distinct seasons- i) Kharif – 69.20 lakh hectares, ii) Rabi – 30.29 lakh hectares and iii) Summer – 5.90 lakh hectares. As per the Agriculture Census Report of 2010-11the total number of operational holdings are 78.32 lakhs and the area operated is 121.61 lakh hectares with an average size of 1.55 hectares. Small and Marginal farmers account for 76% of the total holdings and operate 40% of the total operated area. As per the Population Census of 2011 the number of agricultural labourers in the State is 71.56 lakhs. Contribution of Agriculture to State Gross Domestic Product (SGDP) during 2015-16 was 12.30% compared to 17% in 2010-11. The decline can be attributed to successive drought situation in previous five years.

In the last five years the number of Small and Marginal farmers has increased as there has been more fragmentation.
Cropping Pattern: Karnataka State falls in Zone X (Southern Plateau and Hilly region) and Zone XII (West Coast Plains and Ghats region) as per the Agro-climatic Regional Planning of Planning Commission. The State is divided into 10 Agro-climatic zones on the bases of distribution and percentage of Rain fall, soil quality, height from the sea and on the basis of major crops. On account of this varied agro-climatic features almost all cereals, pulses, oilseeds and commercial crops are cultivated in different parts of the State.
Farmers in Karnataka are very innovative and take lead in diversification as per the market trends. The average area under agricultural crops grown in three seasons viz. Kharif (69.20 lakh ha.), Rabi (30.30 lakh ha.) & summer (5.90 lakh ha.) is 105.40 lakh hectares (Average of 2010-11 to 2014-15). Cereals, Pulses, Oilseeds, Cotton, Sugarcane and Tobacco account for 49%, 24%, 15%, 6%, 5% and 1% respectively of the total agricultural cropped area. Maize, Tur, Bengal gram, Cotton and Soyabean are witnessing increasing trend in recent years, whereas as crops like Sunflower, Jowar, Ragi etc. are witnessing declining trend.

Horticulture profile of Karnataka The geographical area of Karnataka is 190.50 lakh hectare of which an area of 129.00 lakh hectare is cultivable area, which works out to 67% of the total geographical area. As per the estimates for 2015-16, 21.03 lakh hectares area was expected to be covered under horticulture. Horticultural area in the state accounts about 17 % of the total cultivable area. Horticulture - Its Contribution to State GDP:
The total expected GSDP (Gross State Domestic Product) of Karnataka in 2014-15 is about Rs. 907839 crores. Combined Agriculture sector including Agriculture, Horticulture, Forestry, Sericulture, which is 8.81 % is about Rs.79947 crores. Out of this Horticulture sectors contribution to state GSDP is Rs.40002 crores i.e 4.41% . The share of Horticulture in Agriculture GSDP is 34.80%. (Source:DES and Dept.of Horticulture)
Agriculture/Horticulture is the major occupation for rural habitants of Karnataka. Over the years, Horticulture has emerged as one of the potential enterprise in accelerating the growth of economy. Horticulture in Karnataka is heavily dependent on the South West Monsoon since, the extent of arid land is next only to Rajasthan. Only 32.5% of net sown area is subjected to irrigation.
The State has three agricultural seasons- Kharif (April to September), Rabi (October to December) and Summer (January to March). Major Horticultural crops grown are fruits (Mango,Grapes, Pomogranate, Banana, Papaya etc.,) vegetables (Onion, Potato, Tomato, Chillies), Plantaton Crops (Coconut, Arecanut, Coffee) and Spicies (Cardamom, Pepper, etc.,).
Recurring droughts and their effect on Horticulture crops in the State
Most parts of Karnataka encompass vast stretches of dry arid zones. Recurring occurrence of drought and dry spells has been leading to wide spread losses to the horticulture crops. During the last three years, an unprecedented drought has occurred in the state successively and has caused extensive damages/losses to the horticulture crops and also has brought untold miseries to the farmers. Successive drought during the last 3 or 4 years has affected the coconut plantations severely. Coconut is grown in an area of 5,14,887 hectares (2015-16) occupying approximately 25% of the total area under horticulture crops with annual production of about 50,117 lakh nuts. Coconut cultivation in Karnataka is more concentrated in southern districts namely Tumkur, Hassan, Ramanagar, Mandya, Mysore, Chitradurga, Chikmagalur, Chamarajnagar, Dakshina Kannada, Udupi, Uttar Kannada, Davanagere and Shimoga. Most of the coconut plantations in these districts are rainfed and their prospects depend largely on the occurance of satisfactory monsoon rains.
2. Flood Flood has been another Hydro-Meteorological Disaster in Karnataka causing huge loss of life & property. The Floods in 2009 & 2016 in several Districts of North Interior Karnataka destroyed huge amount of Agricultural Crops, damaged Human Settlements and displaced Lakhs of People. The rehabilitation is a humungous task to the State Government.
Causes of Foods in Karnataka
High Intensity Rainfall Heavy Rainfall Reservoir Water Release The rainfall with an Rainfall >= 65mm per day in Huge amount of water intensity above 50mm/hr a given area, can trigger release from the Reservoirs has the potential to generate flash flood specially in the will cause floods in the surface flow which lead to Urban areas. adjoining areas / Districts. inundation / flash flood
The Floods occurred in the Districts of Kalburgi, Yadgir, Bidar, Belgaum and Raichur due to Water release from Reservoirs in the adjoining State of Maharashtra caused huge loss to standing Agricultural crops in 2016. The loss is estimated at Rs.2485 crore. 373519 ha of agricultural and horticultural crops were damaged. Flood Vulnerability map of Karnataka
3. Cyclone Hazard and Vulnerability of Karnataka The coastal districts namely Dakshina Kannada, Udupi, Uttara Kannada with a coastal line of 320 kms and coastal population of 43.64 Lakhs are under the direct threat of cyclones and severe cyclones originating in Arabian Sea and indirect attack of cyclones originating along the Eastern coastline. The high density of population along the coastline of Karnataka has made the population highly vulnerable to the storm surge and high speed wind accompanied with cyclone. Any severe cyclone along the eastern coastline causes heavy rainfall in the interior Karnataka region resulting in damages to crops, buildings, and infrastructure services such as roads and often the impact would be severe disruption in the socio-economic life in these regions. Infrastructure such as rail and road networks which are adjacent to the sea coast are constantly threatened by the erosion caused by giant sea waves particularly during storm surges and cyclones The state is incurring huge expenditure almost every year on prevention of coastal erosion for the 320 Kms of coastal line. The State has been placed under Category P3 (moderate) in terms of proneness to cyclone along with states of Maharashtra and Kerala. Generally, cyclones affect these areas during October to November.
Apart from coastal erosion, the coastal areas are facing disasters such as boat capsizing due to extreme weather conditions in the sea. Impact of cyclone is severe on people under below poverty line, women, elderly people, disabled and children.

Damage to crop and Farmers and vital infrastructure infrastructure like schools, hospitals, roads, bridges, houses, etc Damage to houses, People living within livelihood systems the vicinity of the coast. Severe stress and Affected People psychological disorders
Additionally, both the areas along coastline and interior regions can be affected by gusty winds which can cause damage to property, damage to crops, collapse of trees and in turn threatening lives of people including fishermen, livestock, ships and barges, boats, fishing trawlers at ports. If cyclonic winds are accompanied by heavy rainfall then there is possibility of flooding in low lying areas.
Cyclone Proneness of Karnataka As per “ Cyclone Hazard Prone Districts of India: A report” prepared by NDMA and IMD, the coastal district of Karnataka are in Moderate proneness category. Data regarding to the same is as follows: List of vulnerable districts of Karnataka for Cyclone wind and coastal/inland floodings

3.1 Coastal Erosion The primary causes of coastal erosion in any given region are generally wave action, the interception of littoral drift, sea level and river mouth changes and sand mining. About 30% of the area of the coastal zone is subjected to moderate soil erosion and 16% of the area to severe soil erosion. The annual rates of soil erosion vary from 5-15 tons per hectare (t/ha) to 15-40 t/ha in moderate to severe soil erosion areas. The problem is relatively more severe in Dakshina Kannada and Udupi coasts. The erosion becomes severe due to the synchronization of high floods in rivers with strong wave activity during the southwest monsoon. The most affected locations are Kundapur, Kodi, Hangarkatta, and Bengere. Erosion and bank collapse in the tidal reaches of rivers is also severe and extends at least to about 12 km. This has also been noticed in the Haladi river, Sitanadi near Mabukal and Ullal of Netravathi riverbank. The problem is more severe in Dakshina Kannada and Udupi coasts where about 28% of the stretch is critical. In Uttara Kannada region about 8% of the coast is subjected to severe erosion. 3.4 Salinity Instances of saline water intrusion have been recorded on the coast due to sea erosion and tidal influx in the estuary. Coastal alluvial aquifers are highly permeable and are in hydraulic continuity with sea/estuarine water. The intrusion of saline water into groundwater aquifers and the ingression of seawater to rivers/estuaries are adversely affecting the availability of intrusion is the poor quality of bund constructions causing breaches. To address this problem, Government of Karnataka initiated the construction of sea walls to prevent saltwater entry into the paddy fields.
4. Landslide: Landslides has been one of the majors natural hazards causing enormous destruction in life and property, disrupting communication modes in landslide prone terrain of Western Ghats year after year during monsoon. In Karnataka, the Western Ghats extend from Coorg district in the south to Uttar Kannada district in the north. Major Causes of Landslides in Karnataka
Morphological causes Fluvial erosion of slope or toe or lateral margins Deposition loading of slope or its crest. Vegetation removal (by fire, drought, anthropogenic activity). Geological causes Weak or sensitive materials Sheared, jointed or fissured material Adversely oriented discontinuity (bedding, schistosity, fault, unconformity, contact etc.) Contrast in permeability and or stiffness of materials
Human Causes Excavation of slope or its toe / Loading of slope or its crest Mining Artificial vibration Water leakage from utilities / improper drainage
Major Triggers Rainfall Toe removal Head loading Strength reduction Hazards related to Landslides: Danger to life, infrastructure, social welling and land loss.

Railway lines vulnerable to Lanslide
1. Konkan. 2. SWR rail line between Sakleshpur- Subramanya
Debris and rock slide near Sree Bagilu station) Sakleshpur-Subramanya railway section. Development Induced Landslides
1. More space required for growing population and demand for development 2. Migration of population from flat areas to high grounds 3. High land cost force people of low income groups to live in hutments made in the slopes 4. Blocking of natural drainage 5. Economic activities in forested mountainous lands increasing due to the intensive cash crop plantation such as coffee, tea & rubber etc. 6. Road widening projects. 7. New developmental projects for industries
In a view of the impact of environment by the anthropogenic activities, the relationship between rainfall and geology for landslide to occur and for suggesting low risk hazard free areas for future developmental activities the studies on landslide will be of very important societal issue.
5. Earthquake In recent years much of the seismic activity in the state of Karnataka has been in the south, in the Mysore-Bangalore region. Historically tremors have occurred in many other parts of the state such as Bellary. Recent studies have identified several active faults in the region, in particular in the coastal plain near the towns of Bhatkal and Udipi, trending in an ESE- WNW direction. Many of the faults continue offshore into the Arabian Sea trending in the same direction. There is also no evidence of the southward continuation of the West Coast Fault in the Konkan regions of the neighbouring state of Maharashtra as previously believed. However, it must be stated that proximity to faults does not necessarily translate into a higher hazard as compared to areas located further away, as damage from earthquakes depends on numerous factors such as subsurface geology as well as adherence to the building codes.
