Meteorologically, ± 19% deviation of rainfall from the long-term mean is considered

‘normal’ in India. Deficiency in the range 20–59% represents ‘moderate’ drought, and more

than 60% is ‘severe’ drought.

Rainfall, temperature, evaporation, vegetation health, soil moisture, stream flow, etc. are

some of the critical parameters that are used in drought risk analysis

Life of a farmer is not cumulative values of rainfall, but the type of crop, amount

of rainfall, spread of rains, breaks in rainfall, etc. in relation with other

elements of nature, meteorology, etc.

Page 11: Management of drought

Drought 2009 cause and what can be done?!

The drought is rare of this magnitude and for many people it is a one generation memory. Meteorological and information factors are responsible for this situation. Other cumulative factors are:

· Global recession· Increase in commodity prices· Occurrence of diseases· Increase and decrease in real estate prices· Up and down of stock market· Availability of credit is low· National Rural Employment Guarantee Programme –

Deviation of labor for indirect natural resources enhancement activities rather contributing to the direct production activities. This has lead to Non availability of labor or uneconomical to hire them.

Page 12: Management of drought
Page 13: Management of drought

The drought-prone areas are confined mainly to the peninsular and western parts of the country.

These regions suffer drought mostly due to the cumulative effects of changing precipitation pattern, excessive water utilization and ecologically unsuitable agriculture practices

About 107 mha of the country spread over administrative districts in several states is affected by drought

Page 14: Management of drought

Meteorological :-• Normal precipitation below 25%.

Hydrological :-• Prolonged meteorological drought and drying of

reservoirs, lakes, streams and rivers, cessation of spring flows and fall in groundwater levels.

Agricultural :-• Depletion of soil moisture during the growing season. A

dry situation with 20% probability and rainfall deficiency of more than 25% in drought-prone states of India.

Crop Insurance• A2.1. The National Agriculture Insurance Scheme has been implemented in Andhra

Pradesh since 1999-2000. The schemes are a mix of voluntary and compulsory participation. They are voluntary at the state level in terms of specific areas and crops. Once the specific area-crop combinations have been notified, participation is compulsory for farmers in those areas cultivating the specific crops and taking agricultural loans. In the case of loanee farmers the sum insured may be at least equal to the crop loan advanced. All farmers can insure to the value of the threshold yield of the insured crop.

• A2.2. Eighteen crops are currently insurable under NAIS during Kharif season (e.g., rice, maize, sunflower, groundnut, sugarcane, and cotton) and ten crops during Rabi season (e.g., rice, maize, sunflower, and groundnut). The standard area yield insurance scheme has recently been extended to farm income insurance and rainfall insurance.

• A2.3. The XI Finance Commission noted the need to strengthen the crop insurance scheme as a supplementary measure to what is done by the government for providing relief at the time of natural calamity.

Page 26: Management of drought

Calamity Relief Fund (CRF)

• A2.4. This fund was established separately for each state on the basis of recommendations of the IX Finance Commission and has since been approved for continuation by the X and XI Finance Commissions. This fund should be used for meeting the expenditure for providing immediate relief to the victims of cyclone, drought, earthquake, fire, flood and hailstorm. The table below describes the financial status of this fund over the last 5 years.

Page 27: Management of drought

Drought Proofing ProgramsDrought Prone Areas Program (DPAP) • A2.6. DPAP, a centrally sponsored scheme, in operation since 1973, aims at restoring

ecological balance in the drought prone areas and mitigation of the adverse effects of drought on crops and livestock through integrated development of natural resources by adoption of appropriate technologies. However, the program fell short of its initial objectives despite large expenditure.

• A2.7. DPAP is aimed at developing the drought prone area with an objective of drought proofing by taking up of soil land moisture conservation, water harvesting structures, afforestation and horticulture programs on a comprehensive micro watershed basis. During 1994-95 the program was implemented in 69 blocks of 8 districts. From 1995-96 the program is extended further: 11 districts with 94 blocks under the scheme and Anantapur with 16 blocks under Desert Development Programs (DDP). So far, 3518 watersheds were taken up covering 110 blocks in 12 districts covering an area of 17.6 lakh hectares. Almost 30 percent of the total watersheds in country are located in Andhra Pradesh. Total Rs.507.57 crores are spent towards implementation of the program from 1995-96 to 2002-03. The expenditure for this program is shared by center and state governments in the ratio of 75:25.

Joint Forest Management / Community Forest Management

• A2.8. The Government of Andhra Pradesh adopted in 1992 the Joint Forest Management program which envisages a strategy for production, improvement and development of forest with the involvement of local communities by forming them into Vana Samrakshana Samithies (VSS).

• A2.9. There are 7090 VSS actively involved in protection and development of forests. 8.71 lakh hectares has been treated so far out of 17.40 lakh hectares of forest area under VSS. T he Joint Forest Management program is being supported by the World Bank funded A.P. Community Forest Management Project, NABARD assistant for RIDF schemes and Government of India funded Forest Development agencies.

Indian poverty

• Poverty is widespread in India, with the nation estimated to have a third of the world's poor. According to a 2005 World Bank estimate, 41.6% of the total Indian population falls below the international poverty line of US$ 1.25 a day (PPP, in nominal terms 21.6 a day in urban areas and 14.3 in rural areas).[1] A recent report by the Oxford Poverty and Human Development Initiative states that 8 Indian states have more poor than 26 poorest African nations combined which totals to more than 410 million poor in the poorest African countries.[2]

WATERSHED DEVELOPMENT PROGRAMME (WDP)

Improve and sustain productivity and production potentials of the dry/semi-arid regions of India through adoption of appropriate production and conservation technologies.

Meet the needs of local rural communities for food, fuel, fodder and timber. Improve all types of lands, i.e., Government, Forest, Community and Private Lands falling within a watershed.

Page 42: Management of drought

WATERSHED DEVELOPMENT PROGRAMME (WDP)

WDPs, in short: A holistic approach to improve and develop the economic and natural resource base of dry/semi-arid/fragile regions. In a watershed development program the watershed is the unit for development rather than political or administrative boundaries

Page 43: Management of drought

WDP Activities

• i)Land Development: Levelling and terracing, improving soil quality and productivity; and watershed reclamation.

• ii)Water Development: Promote in situ water harvesting and conservation, establish percolation ponds and open wells, tanks, small reservoirs, and improving water quality.

Page 44: Management of drought

WDP Activities

• iii)Enterprises/Activities: Evolve appropriate farming systems, encourage a crop mix of high value/high yield crops, social/agro-forestry, other income-generating activities like dairying, poultry-keeping, etc.

Page 45: Management of drought

Some Illustrations of Benefits of WDPs

• -Replacing seasonal/annual crops with agro-silvi, agrohorti, silvi-horti; systems on hill slopes/degraded lands. Benefits: reduce soil erosion; arrest surface run-offs.

• -Training water to store excess water run-offs in farm ponds/percolation tanks. Benefits: improve groundwater recharge.

• -Construction of earthen or vegetative bunds or barriers to surface run-offs in a watershed. Benefits: help in moisture conservation.

MGNREGA• 'National Rural Employment Guarantee Act'2005 (NREGA)• Act guarantees 100 days of employment in a financial year to

every household• a social safety net for the vulnerable groups and an

opportunity to combine growth with equity• Structured towards harnessing the rural work-force, not as

recipients of doles, but as productive partners in our economic process

• assets created result in sustained employment for the area for future growth employment and self-sufficiency

• Operationalised from 2nd February, 2006 in 200 selected districts, extended to 130 more districts in 2007-08.

• The remaining districts (around 275) of the country under the ambit of NREGA from 1st of April, 2008

Page 50: Management of drought

Agriculture• India ‘s population is 1.21 billion in 2011. 67% are rural. Majority

are in agriculture. • Importance of agriculture in Indian economy. Although it

contributes only 15% of GDP, the share of workers is about 55%.• Marginal and small farmers dominate• Major crops are rice, wheat, maize, coarse cereals, groundnut,

cotton, sugarcane, fruits and vegetables• 60% of cultivated area is rainfed as only 40% of area is under

irrigation.• Rural poverty is 41%in 2004-05. • Agriculture is a ‘State Subject’. In other words, the policies of

provinces are also important

Page 51: Management of drought

Climate Change / Variability in Semi-arid regions

Climate Variability and extremes are an expected characteristic of semi-arid lands.

The people vulnerable to droughts, which trigger frequent subsistence crises

Increasing crop failures, dislocation, famine, poverty, increases stratification and the social inequities.

BIOCHARCULTURE

Page 67: Management of drought

BiocharcultureBiocharculture is the process of using Biochar,

including cultivation of crops

• Biochar is the charcoal produced from carbonaceous source material. Sink for atmospheric carbon dioxide in terrestrial ecosystems

• Biocharculture is one of the means to integrate for sustainable cultivation and carbon sequestration.

• Biochar is usually produced at around temperatures 300 to 600 degrees centigrade for example as found in the common biomass cook stoves.

• Because of its macromolecular structure dominated by aromatic C, Biochar is more recalcitrant to microbial decomposition than uncharred organic matter
