The document discusses the role of agricultural extension in addressing climate change in Odisha, India. It outlines that climate change is negatively impacting agriculture in Odisha through increased temperatures, erratic rainfall patterns, and more frequent extreme weather events. Agricultural activities also contribute to climate change through greenhouse gas emissions. The agricultural extension system can help reduce farmer vulnerability by promoting adoption of climate-resilient practices like crop diversification and integrated nutrient management. Agricultural extension must develop awareness through education and training programs to motivate sustainable agriculture.

Agriculture and fisheries are highly dependent on specific climate conditions. Trying to understand the overall effect of climate change on our food supply can be difficult. Increases in temperature and carbon dioxide (CO2) can be beneficial for some crops in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers. Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt ecosystems. Overall, climate change could make it more difficult to grow crops, raise animals, and catch fish in the same ways and same places as we have done in the past. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices and technology.

Climate change, its impact on agriculture and mitigation strategiesVasu Dev Meena
According to IPCC (2007) “Climate change refers to a statistically significant variation in either the mean state of the climate or in its Variability, persisting for an extended period (typically decades or longer)”.
Climate change has adverse impacts on agriculture, hydropower, forest management and biodiversity.
In the long run, the climatic change could affect agriculture in several ways such as quantity and quality of crops in terms of productivity, growth rates, photosynthesis and transpiration rates, moisture availability etc.
Climate change directly affect food production across the globe.

Global climate change is a change in the long-term weather patterns that characterize the regions of the world. The term "weather" refers to the short-term (daily) changes in temperature, wind, and/or precipitation of a region. In the long
run, the climatic change could affect agriculture in several ways such as quantity and quality of crops in terms of productivity, growth rates, photosynthesis and transpiration rates, moisture availability etc. Climate change is likely to directly impact food production across the globe. Increase in the mean seasonal
temperature can reduce the duration of many crops and hence reduce the yield. In areas where temperatures are already close to the physiological maxima for crops, warming will impact yields more immediately (IPCC, 2007). Drivers of climate
change through alterations in atmospheric composition can also influence food production directly by its impacts on plant physiology. The consequences of agriculture’s contribution to climate change, and of climate change’s negative impact on agriculture, are severe which is projected to have a great impact on food production and may threaten the food security and hence, require special agricultural measures to combat with.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. • INTRODUCTION:
• Climate change is any long term substantial
deviation from present climate because of variation in
weather and climatic elements.
• The earth’s natural climate is changing continuously
since ancient times . Presently it has got momentum due to
various artificial causes of modern technology in
agricultural practices, heavy deforestation and
industrialization .
3. • The hike in population growth has raised awfully the
requirements of the people and consequently the
exploitation of natural resources has increased abruptly
leading to climate change by the emissions of
• Carbon dioxide,
• Methane,
• Nitrous oxide,
• Hydrofluoro carbons,
• Perfluoro carbon,
• Ozone and
• Sulfur hexafluoride
which have high global warming potential.
4. • Out of the various artificial causes, agriculture
ranks 3rd
as a contributor to the enhanced green
house effect after energy and industry.
• Land use related emissions like from Rice
cultivation, Manure management, Crop
management, Emissions from soils & Enteric
fermentation currently account for nearly 1/3rd
of total
warming from green house gases, globally.
5.
6. Agriculture, the largest human activity depends on
climatic parameters. More than 50% difference in
crop yield is due to climatic variation. Manipulation
of climate is beyond our control.
But
we can manipulate the cropping environment(soil,
water & nutrient management practices).It
influences the crop-pest equilibrium.
7. VULNERABILITY OF INDIA TO CLIMATE
CHANGE
India is most vulnerable to climate change
because of….
• A unique combination of its geography
• Diverse population characteristics
• Extremely high dependence on fossil fuels
• With nearly 700 million rural population directly
depending on climate sensitive sectors (agril.,
forests, fisheries) & natural resources (water,
biodiversity, mangroves, coastal zones,
grasslands) for their subsistence & livelihoods.
8. VULNERABILITY OF ODISHA TO CLIMATE
CHANGE
Odisha may be better termed as ‘’Disaster
Crown’’of india. (In the last 42 years, the state
has experienced 34 disasters of varied intensity)
as it is one of the most vulnerable states to climate
change and the impacts of climate change have
been serious. It is the hot spot of climate change
and because of the poor people, they are more
vulnerable to such changes.
9. CLIMATE CHANGE EXPERIENCED IN ODISHA
a) Odisha is getting warmer day by day
b) Monsoon rain pattern is very erratic.( Annual
rainfall decreased between 1950 and 1990 by
19 to 225 mm, increasing in the coastal districts
and declining in the interior districts, increasing
in May and Oct. and declining in Nov. to March).
c)Low pressure numbers over the Bay of Bengal is
increasing( Low pressure reached 12 in 2006
and 14 in 2007. Super Cyclone in 1999…..)

heavy rainfall,daily max temperature is increasing,
no.of hot days also increasing)
e)Threat to 480 KM long coastal settlements.
(Eroded beach, encroached several kilometers to
the land)
12. FUTURE PROJECTIONS OF CLIMATE
CHANGE IN ODISHA (Pasupalak 2008)
• Late monsoon onset and more pre-monsoon rainfall.
• Reduced post monsoon and winter rainfall.
• Less rainfall in February, June and October.
• More number of cloudy days.
• Increased day and night temperatures in all the months
except July.
• Maximum increase in temperature in post-monsoon
followed by summer.
• Extended summer up to June.
• Increased number of hot, humid summer days in coastal
areas.
13. • Warm and short winter with fewer cold nights in western
Orissa.
• More frequent extreme weather events, such as hot
extremes (maximum temperature above 450
C) and
prolonged heat waves.
• More number of very heavy rainy days (> 125 mm per
day).
• Prolonged dry spell due to most rainfall over few days.
• More number of low-intensity low pressures at the Bay of
Bengal.
• More intense tropical cyclones with larger peak wind
speeds and heavier rainfall.
• Increased risk of drought and flood during monsoon.
• Intense storms resulting in loss of the rain water as direct
runoff resulting in reduced groundwater recharging
potential.
14. ADVERSE EFFECTS OF CLIMATE CHANGE
IN ODISHA
The trend analysis and the future projections agree
to result in reduced yield of crops, substantial yield
losses in winter crops, more crop loss, water logging,
increased soil structure damage, soil erosion, higher
incidence of pests &diseases etc.
And thus, future climate change is likely to adversely
affect agriculture, livelihood, food security and water
resource.
15. ROLE OF AGRICULTURAL EXTENSION TO
REDUCE VULNERABILITY
A range of adoption measures(crop
diversification, introducing new crop variety,
mixed cropping/inter cropping, altering sowing
time, integrated nutrient management, integrated
pest management, draught management, flood
management ,land management and integrated
farming system approach) are available to
reduce vulnerability to climate change by
enhancing adaptive capacity and increasing
resilience.
16. A large number of technologies (improved
land management ,restoration of degraded land,
improved composting, using efficient agril.
machineries and adopting farm forestry and
plantation with due emphasis on natural resource
management developed for sustainable
agriculture have strong mitigation potential. The
practices having mitigation potential can
collectively make a significant contribution to
increasing soil carbon sinks, reducing green house
gases emissions, and by contributing biomass
feedstock for energy use.
17. Technology developed in research station is
of no use, unless it is appropriately transferred
and adopted by the end users. For the purpose of
transferring appropriate technology to the farming
community, development of competence,
consciousness about the roles, possession of
certain qualities and knowledge about methods for
effective transfer of technology are essential. Here
the term “agricultural extension” comes into the
play. It is the nucleus of the agriculture
development cell. It is not to aim at only on
technology transfer but also on the human
resource development in agriculture in holistic
manner.
18. To reduce the vulnerability to climate change,
“agricultural extension”can go a long way with:-
A. RIGHT EXTENSION POLICY OF STATE GOVT.
B. SUSTAINED EFFORTS OF HIGHLY DEDICATED
RESEARCH & EXTENTION SCIENTISTS
C. RESPONSIVE & DEDICATED EXTENTION
FUNCTIONARIES OF AGRICUTURE & ALLIED
SECTOR (GOVT.DEPT & N.G.O. ALONGWITH THE
INPUT SUPPLIER,FINANCIAL
INSTITUTION,MARKET AGENTS,PROCESSORS
ETC.)
D. EFFECTIVE EDUCATION,TRAINING AND PUBLIC
AWARENESS.
19. RIGHT EXTENSION POLICY OF STATE GOVT.
I. Need based Revised agricultural extension policy
(may now be better termed as Climate Led
Extension as 3rd
generation extension after
production led extension and market led
extension ) frame work development
II. Restructured extension network to reach the
increased population and to meet the effects of
climate change.
III. Recruitment of committed and dedicated
extension personnel.
20. IV.Orientation training to the newly recruited
personnel to get introduced to the new
organization /capacity building training to all the
officers to incorporate climate change
concerns.and the capacity building at local level
also must not be ignored.
V.Providing proper working environment to the
extension personnel and encouragements through
periodic promotion/ performance based incentives
etc.
VI.Special emphasis on strengthening the ATMA like
institutions for multi disciplinary extension services
to the farmers.
21. EFFORTS OF HIGHLY DEDICATED
RESEARCH & EXTENTION SCIENTISTS
The organizational set up plays the key role
for setting up an enabling environment,. The co-
ordinated efforts of highly dedicated research
scientists and extension scientists can bring in the
improved decision making on continuous basis at
state level for effective implementation to achieve
the desired goal of sustainable agricultural
production
22. RESPONSIVE & DEDICATED EXTENTION
FUNCTIONARIES OF AGRICUTURE & ALLIED
SECTORS INCLUDING THE GOVT.
DEPARTMENTS & NGOs.
I The extension personnel must be competent with
scientific,technical and managerial skill and above
all he should be willing to work for socio-
economic development of the farming community.
This will help in proper technology dissemination,
understanding and adoption by the target
groups.
II.The participatory approaches to be followed for
climate change.
23. III.”Learning by doing” being an effective method
of motivation, a few demonstration projects are to
be used.
IV.The extension personnel including all the stake
holders (members from Govt.Dept & N.G.O.
alongwith the input supplier,financial
institution,market agents,processors etc.) should
personally,socially and organizationally be
held responsible in the multi-stage drama
undertaken to develop the farming community.
24. EFFECTIVE EDUCATION,TRAINING AND
PUBLIC AWARENESS.
In order to combat the effects of climate change
alongwith the capacity building of extension
personnel,the first and foremost step to be taken
up by the state is to develop teaching material for
imparting effective education, training and
public awareness under multi-tier approach.
25. The different tools for the purpose are :-
I. For civil society:The reading materials must reach
the would be benefitted professionals.
II.For school curriculum: The reading materials must
be prepared for different levels.
III.For the community: The small book and literatures
as reading materials must be prepared in
participatory approach with the community in
simple language and with more pictorial features.
IV. For the policy makers, decision makers and
planners: The reading materials with exhaustive
research data on climate change and its effect
with case studies.
26. V.By organizing workshop and seminars : For faster
dissemination to different levels.
VI.Using communication media: Newspaper, TV,
Radio Street Play etc.
Here, it is an appeal to all,to develop such a
slogan or song or any other strategy which will
create mass awareness for taking environment
friendly activities as it often happens in
viewing World Cup cricket and now like the
most popular enchanting song of
“Kolaveri,Kolaveri...D’’.
27. Conclusion
Most of the climate change studies have
highlighted more on macro/global perspectives of
climate change. In the recent past ,the state level
studies have also not lagged behind. Under such
circumstances, the present need is the effective
education, training and creating public
awareness along with micro-level studies on the
one hand . On the other, the vast majority of the
population being dependent upon the farming for
their livelihood, the agricultural extension can
instill awareness and each individual will start to
contribute their bit in climate change of Odisha.

33. MILANKOVITCH CYCLES
• Eccentricity constantly fluctuating, orbital shape (0 to
5% ellipticity, currently 3%) on a cycle of about
100,000 years. Causes prominent changes in the
Earth's climate and glacial regimes.
• Earth's axial tilt occur on a periodicity of 41,000
years from 21.5 to 24.5 degrees. Today the Earth's
axial tilt is about 23.5 degrees, which largely accounts
for our seasons. A smaller degree of axial tilt would
promote growth of ice sheets.
3. Earth's precession: Earth wobbles from pointing at
Polaris (North Star) to pointing at the star Vega, has
a periodicity of 23,000 years. Due to this wobble a
climatically significant alteration takes place.
*At present, only precession is in the glacial mode, with tilt and eccentricity not
favorable to glaciation

because of…
• A unique combination of its geography
• Diverse population characteristics
• Extremely high dependence on fossil fuels
• With nearly 700 million rural population
directly depending on climate sensitive

53. Why climate change is so important to agriculture ?
• Agriculture is the largest human activity in
the world which depends on climatic
parameters. More than 50% differences in
yield is due to climatic variations.
• A genotype gives good yield only under
suitable climatic conditions and other
management practices.
• Manipulation of climate is beyond our
control, but we can manipulate environment
(soil, water and nutrient management
practices).
• It influences crop-pest equilibrium.
Agriculture→ Small & Marginal farmers → rural poor → Handicapped ecology → Coastal areas
54. Effect of climate change on crops
• Growth
CO2 rise
-Favours drymatter
-Reduces transpiration
Temperature rise
-Reduces drymatter
-Increases transpiration
• Development
-Accelerates maturity
• Quality
-Less protein content
• Pest dynamics changes
• New weed flora
• Soil degradation
55. Impact of climate change on crop production
• Increased atmospheric CO2 concentration has a fertilization
effect on C3 plants but is negated by increased temperature.
• Increase in temperature reduces crop duration, increases crop
respiration rate and alters photosynthates partitioning to
economic products (for 1°C increase in temp. wheat yield
decreases by 428 kg/ha, for 2°C temp. rise rice yield decreases
by 750 kg/ha)
• Increase in extreme weathers adversely affecting agril.
productivity
• Decrease probability of yield reduction due to cold waves &
frost damage
• Tropospheric ozone causes foliar injury
• Affect quality of fruits, veg., tea, coffee, aromatic & medicinal
plants
• Ultra violet radiation damages nucleic acids creating long

64. Anthesis
• The response of rice to high temperatures differs according to the
developmental stage with high temperature tolerance at one
developmental stage may or may not necessarily lead to tolerance
during other stages.
• Processes close to the meiotic stage during tetrad formation and
young microspore stage are most sensitive to high temperature
during microsporogenesis. A significant reduction in pollen
production at 50
C above ambient air temperature was attributed to
impaired cell division of microspore mother cells.
• Advancing peak anthesis toward early hours of the morning is an
efficient strategy to escape high temperatures during later hours of
the day. Significant genotypic variation for early morning peak
anthesis exists in rice germplasm with O. glaberrima (CG14) having
the ability to flower immediately after dawn, potentially escaping high
temperatures during the later hours of the day
65. Ripening phase
• High temperature affects cellular and developmental processes
leading to reduced fertility and grain quality.
• Decreased grain weight, reduced grain filling, higher
percentage of white chalky rice and milky white rice are
common effects of high temperature exposure during ripening
stage in rice.
• In addition, increased temperature causes serious reduction in
grain size and amylase content further reducing the potential
economic benefits farmers can derive from rice cultivation.
66. Spikelet fertility of BKN6624–46–2 exposed to high
temperature of 350

panicle development for 5 days
The extreme sensitivity of high temperature during
anthesis leading to spikelet sterility: (A) high
temperature for 4 h, (B) high temperature for 1 h, (C) 1
h before the onset of high temperature, (D) 1 h
immediately after high temperature exposure, and (E)
beyond 1 h of high temperature exposure
Flowering patterns of O. sativa cv. IR64
under both control and high temperature
67. High night temp.
• Grain yield declined by 10% for each 10
C increase in
minimum temperature in the dry season. The decrease
in radiation and increase in minimum temperature were
identified as the reasons for the yield decline.
• Although, high temperature at both day and night
reduced the duration of grain growth, the rate of growth
was lower in the early or middle stages of grain filling,
and also reduced cell size midway between the central
point and the surface of endosperm at high night
temperature (22/340
C) than at high day temperature of
34/220
C
68. Effects of enhanced CO2 on crop growth
• C3 plants (Wheat, rice, soybeans etc.) would
respond readily to increased CO2 levels.
• C4 plants (Corn, sorghum, sugarcane, and millet)
would be less responsive to enriched
concentrations.
• Higher levels of atmospheric CO2 induce plants to
close stomata.
• Under CO2 enrichment crops may use less water
while producing more carbohydrates and improve
water-use efficiency.
69. Change in yields of 4 cereals, due to increase
of 2 and 4 °C in average global temp.

• Grain yields of wheat decrease
by 17% with a 2o

temperature.
• Increase in CO2 to 550 ppm
nullify the effect of 2o

temperature.
• Effect of climate change

• Positive (up to 25%) or
• Negative (up to 30%)

71. Impact of climate change on fresh water
availability
• Climate change will modify rainfall, evaporation,
runoff and soil moisture storage. More runoff will
cause flood and needs to be stored.
• Increased evaporation from the soil and accelerated
transpiration in the plants will cause moisture stress.
Crops will need frequent irrigation.
• Climate change affects the availability of fresh water
for irrigation. In the Himalayas it will increase in
short run but in the long run will decrease
considerably.
• Lowering of ground water and decline in quality
because of intrusion of sea water
72. Impact of climate change on soil health
– Reduces soil organic matter both in quantity & quality
– Reduces soil moisture availability
– Crop residues under elevated CO2 will have wide C:N reducing their
decomposition and nutrient supply
– Decreases in microbial population reducing soil productivity and nutrient
cycling
– Affects soil structure
– Reduces fertilizer and irrigation use efficiency (increase temp. will increase N
mineralization but there will be more volatilization & denitrification loss)
– Additional application of fertilizer may be needed to counteract the speed up of
the natural decomposition of organic matter and increase the rates of other soil
processes due to higher air temperature and enhance crop growth that can
result from increased atmospheric CO2
.
– The continual cycling of plant nutrient may enhance CO2
and N2
O gas emissions
More prone to erosion, creating sedimentation in streams and reservoirs
– Creates waterlogging, soil salinity problems, salt water ingression in coastal
areas
– The process of N fixation, is predicted to increase in warmer conditions and
with higher CO2
, if soil moisture is not limiting.
73. Impact of climate change on pest
• Increasing temp. increases the rate of development of insects thereby
decreasing development period
• Monocyclic diseases & univoltine insects are less influenced whereas, polycyclic
diseases become epidemic with climate change
• Expansion of geographical range of insects to regions where warmer winter
temperatures allow their over-wintering survival and increase the possible
number of generations per season.
• Changes in crop pest synchrony
• Increase risk of infestation
• Conditions are more favorable for the proliferation of insect pests in warmer
climates. (In UK, for last 10-15 years aphids are hatching earlier and their
population is growing)
• Crop-pest interactions may shift as the timing of development stages in both
hosts and pests is altered.
• Rate of evolution will increase in hotter, drier conditions and in 'extreme
years‘
• Pests and diseases from low latitude regions where they are much
more prevalent may be introduced at higher latitudes.
74. Effects of droughts, heat waves,
wind storms and floods on insects
• Drought/Heat waves – Mealy bugs,
scales, mites, borers, thrips, rodents
will increase
• Wind storms – Coconut eriophyid mite
will increase
• Floods – cut worms will increase
• Heavy rainfall – Snails and slugs will
increase
75. Effect on Insecticide Use Efficiency
• Entomologist predict more generation of insets in warm
climate that necessitates more number of insecticide
application
• It will increase cost of protection and environmental
pollution
• Synthetic pyrethroids and naturalites (Bio-pesticides,
Plant products) will be less effective in higher
temperature
• It is advisable for the farmers not to use insecticides
with similar mode of action frequently, to avoid
development of resistance in case of more number of
applications
• Cultural management practices e.g. early planting may
not be helpful because of early emergence of pests due
to warmness
76. Impact of climate change on livestock &
fishery
• Affects feed production & nutrition of livestock. Less
fodder production due to increased water scarcity.
More lignification of plant tissues due to temp. rise
reducing digestibility.
• More impacts of vector borne diseases
• Global warming increases water, shelter & energy
requirements to meet the projected milk demands
• Aggravate heat stress in dairy animals reducing their
reproductive performance
• Increase water temp. affects fish breeding, migration
& harvest
• Increased temp. & tropical cyclonic activities affect
capture, production & marketing cost of marine fish

82. Projected effects of climate change on Agriculture-
special emphasis in Orissa
• Reduced yields of crops due to warm days and nights.
• Decreased grain yield of rice (9%) by 2020 due to accelerated
senescence and higher chaffyness. (S.cane in Maharastra by
30%, rice in flood prone coastal Orissa by 12%)
• Substantial yield losses in winter crops. Temp. ↑0.5 o
C ↓wheat
yield by 0.45 t/ha, ↑2.0 o
C ↓rice yield by 0. 75 t/ha in efficient
zone & by 0.06 t/ha in coastal zone.
• Temp ↑by 1-4 o
C ↓yields of rice by 0-49%, potato by 5-40%,
mung by 13-30% & soybean by 11-36%.
• India would lose 3.9 mt wheat by 2020, 11.7 mt by 2050 & 23.5
mt by 2080.
• India loses 1.8 mt milk due to climate stresses
83. • Less elongation of rice grain and lower quality of rice due to warm
nights during post flowering period (basmati rice)
• Direct sown rice at more risk due to extended summer and less
rainfall in June.
• More crop loss, waterlogging and difficulty in cultivation due to
more heavy rainfall events.
• More crop loss and land degradation due to increased drought
occurrence.
• Increased risk of soil damage and erosion due to soil wetness,
waterlogging and flooding.
• Increased salinisation of the coastal areas, particularly Mahanadi
delta.
• Long-term loss of soil carbon stocks, soil degradation
• Increased crop WR due to accelerated evapotranspiration.
• Decreased use efficiency of N fertilizers.
• Shift in weed flora
• Higher pest incidence such as increasing infestation of rice crop by
swarming caterpillar, hispa, stem borer and BLB.
• Loss of cultivated land by sea water intrusion, inundation and
coastal erosion in low-lying coastal areas. Land dispute between
migrant & established communities
84. ADAPTING AGRICULTURE

88. Water saving techniques in rice
• Proper land leveling and puddling.
• Growing rice in a compact rather than in isolated patches.
• Continuous shallow sub. (5+2 cm) than deep sub. saves 10-50% irrigation
water
• Saturation throughout is optimum in shallow WT (20-30 cm in rabi and 20-
45 cm in kharif)
• Recommended practice is 3 DADPW during kharif (5-7 irrigations) and
1 DADPW during rabi season (13-15 irrigations), water saving 9-27%.
• Bed planting saves 26-42% water as compared to conventional planting.
• Drainage at max. tillering or even at PI in iron toxicity area is beneficial
• Drainage at dough stage along with at max. tillering increased head rice
recovery by 10%.
• Draining the field gradually 15-20 days after flowering facilitates
mechanical harvesting and timely sowing of succeeding crops, saves
16-22 cm water.

102. Resource conservation equipments
• Rotavator saves 50 % fuel and helps in preparation of
better quality seed bed
• Zero till drill increases yield by 5–10% and saves of
Rs. 2000-3000/ha
• Pressurized irrigation saves 20–30 % water
• Rotary power weeder saves 20–30 % time and labour
• Vertical conveyer reaper/combine helps in timely
harvesting
• Multicrop thresher saves 50 % labour and time and 54
% cost of threshing
• Improved manual harvester for mango & kinnow
causes no damage to fruits with higher harvesting
capacity
103. Capping Methane emission in rice fields
• The balance CH4 out of the action of Methanogens &
Methanotrophs in rice field is released to the atm. through
ebullition, diffusion & rice plant system (at active growth
stage by aerenchymatous tissues through leaf sheath)
• Direct sowing
• Addition of composted or partially composted OM
• Alternate wetting & drying (Aerobic/SRI), mid-season
/intermittent drainage
• Short duration varieties with low emission potential i.e.,
capacity to oxidise rhizosphere Methanotrophs
(Methylomonas, Methylobacter, Methylomicribium,
Methylosinus, Methylocystis, Methylococcus
• Incorporation/deep placement of fert., lower dose, use of
Nitrification inhibitor (neem product), slow release fertilizers
104. Reducing methane emission from ruminants
• Improving productivity (by nutrition, reproduction,genetics)-less
animals required to produce the same amount
• Nutritional management: High grain diet, no over matured
forage, more legumes, low feeding frequency, grinding or pelleting
of forage, use of preserved forage (silage)
• Manipulation of rumen fermentation ( which favours propionic
acid formation & discourage acetic acid formation):
– addition of fats to increase energy density of diet thereby lowering
intake of fibrous feed
– Use of propionate precursors (pyruvate, oxaloacetate, malate,
fumarate, succinate)
– Defaunation (removal of rumen ciliate protozoa, the site for
attachment of Methanogens, from rumen)
– Stimulation of acetogens to rechannelise the substrates for
alternative products like aetate other than methane
– Ionophores like monensin, lasalocid, salinomycin will inhibit growth of
Methanogens
– Adding methane oxidizers from gut of young pig to rumen fluid in vitro
– Immunizations against Methanogens (Methanobrevibacter,
Methanosarcina, Methanomicrobium)

131. CONCLUSION
• It is the bitter truth that ‘what we achieved in the
name of development only by the cost of climate
change which threaten survival of human race in
future’.
• Dr. M. S. Swaminathan said ‘Our present Indian
agriculture is vulnerable to climate change and
climatic hazards due to dependence on less no.
of crops. Therefore we have to go for crop &
enterprise diversification.
• More research should be done regarding climate
change and its impacts.
132. Concerns
Insufficient information on how climate trends
will affect the suitability of specific crops and
cropping practices in specific areas.
Insufficient information on how climate trends
will affect the incidence and evolution of
diseases and pests in specific areas.
Lack of appropriate crop varieties and
agronomic practices for more variable and more
risky agriculture.
Continuing growth and demand for food.
Declining natural resource base, in which soil
fertility is increasingly depleted and water is
becoming scarce.
134. Scenario-1: Early onset and sudden stoppage of monsoon
(There is more likelihood of mortality of sprouts/seedlings and difficulties in sowing)
Uplands
• When there is more than 50% mortality resow the crop up to July after receipt of
sufficient rain water
• Sowing of low water requiring nonpaddy crops like ragi (Bhairabi, Dibyasinha, Godavari),
Greengram (K-851,Sujata, PDM-54),Blackgram (T-9, Pant U-19, Pant U-30,Sarala), Cowpea
(SEB-2, Pusa Barsati,Utkal Manika), Sesame (Uma, Usha, Nirmala, Prachi),Ricebean
(RBL-6, BRB-1), Castor (Jyoti, Kranti, Harita) is preferred to paddy
• If mortality is less than 50% the crop may be gap filled
• Cultivate vegetables-cowpea, guar, radish, runner bean,okra, cauliflower, Brinjal, tomato
where ever possible
• Niger (Deomali, Alasi-1) and horsegram (urmi ) to be sown in August.
• Spray the crop with potassium silicate (10%) or Cycocel (10 ppm) to overcome drought
effect
• In row sown crops complete hoeing, weeding followed by ridging to the base of the crop
rows at 20 DAS for in-situ moisture conservation
DROUGHT MANAGEMENT
135. Scenario-1: Early onset and sudden stoppage of monsoon (cont.)
Medium and low land
•If rice plant population is less than 50%, resow the crop.
•Early medium duration varieties may be selected.
•Sprouted seeds may be direct seeded or
•fresh seedlings of early varieties may be raised for transplanting.
•If rice plant population is more than 50%,carry out weeding and adjust
the plant population by khelua and clonal propagation. Raise
community nursery of rice for transplanting at a reliable water source
to save time for further delay.
•Sow the seeds at 3-5 cm depth by punji method (10-15 seeds at one
point), cover it with a mixture of FYM:SSP (10:1) to avoid seedling
mortality due to moisture stress in low land
•In saline soils use green leaf manure/ FYM, sow sprouted seeds gap fill
the crop by clonal propagation
136. Scenario-2: Late onset, uplands not covered till mid July
• Sow drought tolerant nonpaddy crop like ragi, greengram, blackgram,
cowpea, guar, sesame, castor in place of upland rice
• Maize and cowpea may be grown in the Ist
week of August to meet the
fodder crisis
• Niger (Deomali, Alasi-I) and horsegram (urmi) are to be sown in August
• Grow sweet potato vars. Like Gouri, shankar, Samrat, Shreenandini,
Shreebhadra, Shreeratna, in ridges and allow the furrows to conserve
rainfall
• Grow vegetables like tomato, cauliflower, radish, brinjal, runner bean, in
the inland hilly districts and cowpea, guar, lady’s finger and chilli in the
coastal plains
• Apply full P,K and 20%N as basal along with well decomposed organic
manure for early seedling vigour
• Harvesting excess runoff for its recycling as lifesaving irrigation
137. B. Mid season drought (1st
Aug to 15st
Sept)
Scenario-3: Non-paddy crops in uplands affected• Complete hoeing and weeding in non-paddy
crop field to provide dust mulch
• Weeding groundnut 45 DAS disturbs the
pegging process. So prune the weeds with
sickle
• Apply post emergence spray of Quizalofop
ethyl 5% EC @ 0.05 kg/ha in 500 l water to
control grassy weeds in groundnut/jute
• Spray 2% KCl + 0.1ppm boron to blackgram
to overcome drought situation
• Foliar application of 2% Urea at preflowering
and flowering stage of greengram is helpful
in mitigating drought
138. Scenario-3: Non-paddy crops in uplands affected (cont.)
• Spray 1% urea in brinjal, take up spray against mealy bugs and mite
which are more prevalent in dry weather
• Top dress the crop after receipt of rain
• Remove the borer affected tillers/late formed tillers/dried leaves in
sugarcane and follow wrapping and propping in chains. Stripe the
lower 4-5 leaves
• Spray Planofix 10 ppm at 45 DAS and 20 ppm 10 days later to prevent
boll shading in cotton
• Spray 2% urea in late planted jute to encourage growth
• Top-dress N to ginger and turmeric @ 60 and 30 kg/ha respectively
after receipt of rainfall followed by mulching
• Practice mulching with organics to extend period of moisture
availability
• Thin out to the extent of 25% and use removed plants as cattle feed
• Close the drainage holes and check the seepage loss in direct sown
medium land rice regularly
139. Scenario-4: Beushaning of rice delayed
• Do not practice beushaning in rice, if the crop is
more than 45 days old
• Weed out the field without waiting for rainfall
• Go for gap filling using seedling of same age or
clonal tillers to have a uniform distribution of plant
• Strengthen the field bunds and clog the holes to
check seepage loss
• Withhold N fertilizer application up to receipt of
rainfall
140. Scenario-5: Transplanting of rice delayed/seedlings overaged
(Generally in this case rice seedlings are overaged)
• Seedlings up to 45 and 60-70 days old can be transplanted in case of
medium land and late duration rice vars., respectively without much
reduction in yield
• Remove the weeds and follow plant protection measures against blast
in nursery
• Pulverize the main rice field in dry conditions, if it is not ploughed
earlier to save time in final puddling
• Use tractor/power tiller/tractor mounted rotavator for speedy land
preparation/puddling
• Follow closer spacing using 5-7 seedlings per hill
• Apply 50% recommended N at the time of transplanting
• Apply life saving irrigation to maintain the nursery seedlings in good
health
• Don't top dress nitrogen in nursery
141. Scenario-6: Beushaned/transplanted rice
affected at early vegetative stage
• Provide protective irrigation
• Remove the weeds and follow plant protection
measures
• Withhold N fertilizer application up to receipt of
rainfall
• Apply K fertilizers wherever soil moisture allows
or wait up to receipt of rainfall
• Strengthen the field bunds and clog the holes to
check seepage loss
142. C. Late season drought (16th
Sept to 31st
Oct)
Scenario-7: Medium and lowland rice affected at vegetative/ reproductive
stage
It occurs as a result of early cessation of monsoon rains. The
management practices are :
•Provide protective irrigation
•Provide irrigation at critical stages
•Crops like cowpea,maize, green gram may be harvested for fodder
purpose to avoid their failure as grain crop
•When soil becomes hard it is difficult to dig up groundnut from the field,
sprinkle water from WHS
•Under situation of complete failure of Kharif crop dismantle it. Dibble the
pre- rabi crop
•The ideal pre-rabi crops for residual moisture are horsegram, castor,
niger, black gram and sesame in uplands and well drained medium lands
143. Pre-flood planning
• Suitable variety (Local, improved)
• Sufficient seed stock for resowing after early flood
• Varieties for late planting (CR 1014, 1018, Jagannath,
Mahsuri, Padmini, IR 36, Lalat, Konark)
• Long duration var in loland (Sarala, Durga,
Varshadhan, Upahar)
• Direct seeding
• Dry nursery
• Contingency nursery
• Double transplanting/clonal tillers
