Arsenic contamination in West Bengal (Source: http:/www.soesju.org)
Arsenic Toxicity Symptoms
• Increased incidence of Lung disease and Hypertension was
found in arsenic exposed people compared to unexposed
people.
• High Arsenic (As) level in Urine & Hair has been observed in
spite of intake of safe water.
• Arsenical symptoms persist despite safe water intake for 5
years or more.
• Significant Arsenic excretion occurs through urine and hair in
these subjects.
• Thus combined effect of high Arsenic in food & water have
additive effect on Biomarkers & human health.

Promotion of the rice cultivars: IR 64 or Khitish for arsenic
contaminated areas as replacement of Satabdi.
Low arsenic accumulating crops like potato, Pumpkin, Sesame,
Green gram , sunflower can be safely included in cropping sequence to minimize
the arsenic entry into the food-chain.

Introduction of surface irrigation system through installation of largescale water harvesting structures in the contaminated areas.
Recommendations for immediate implementation
Reduced use of ground water as irrigation source:
Use of
pond (surface) water (harvested rain water) has been observed to reduce arsenic
loading in edible parts of different crops like kharif rice (24%), boro rice (20%),
mustard (30%), wheat (31%), potato (30%), as compared to the crops exposed to
irrigation through shallow tube well water (STW).
Increased use of Organic Manure:
Vermicompost, oil cakes
(mustard and castor cakes), FYM, Green manure (Sesbania rostrata) were
observed to reduce soil arsenic availability to standing crops. (Vermicompost
was most efficient in this regard, reduced 55.2% grain Arsenic loading in boro rice
over the control counterparts.)
Inorganics as soil amendments:
ZnSO4, FeSO4, CaSiO3, elevated
levels of phosphate were established as efficient inorganic amendments to reduce
soil arsenic availability to standing crops.

Areas of prioritization
Agricultural development in the State of West Bengal in future may have the strategy
with following prioritization. While strategy for the next plan will be relatively a
short-term one, that up to 2025 A.D. will be long-term strategy.
The objectives of such agricultural development plan would be as follows:
 Increasing agricultural production and productivity using natural resources as
much as possible without harming the existing agro-ecological balances.
 Genetic improvement of crop varieties with higher yield potentiality, adaptability
under various biotic and abiotic stresses keeping in view the changing climate,
following well planned research and developmental programme suitable for
different agro-ecological situations.
 Employment generation as well as livelihood security of the vast rural population
of the State.
 Generation of viable, low-cost agro-technology suitable for different agroecological situations.
 Capacity building of the farming communities through extensive training and
demonstration programme:
 Institution credit support to the farmers.
 Agro-based processing industries.
Major Strategies:
• To maintain the productivity of major cereals in
irrigated agro-ecosystem, especially in rice.
• Value-addition in rice, pulse etc for better market price
vis-à-vis more earning from the same area of land.
• Promotion of quality seed/planting materials
production for rice, pulse, vegetables and fruits.
• Development of abiotic and biotic stress tolerant variety
for rice, pulse, jute, fruits and vegetables using modern
tools and techniques.
Constraints (BCKV)
 Inadequate infrastructure for adopting modern
tools and techniques due to insufficient fund flow.
 Shortage of manpower, infrastructure and resources
in the Zonal Research Stations for undertaking zone
specific need-based research and extension
programme.
 University has shortage of man-power which is
impeding teaching , research and extension works.
 Lack of fund for translational research, particularly
in the field of variety development.
Emerging areas of research for innovation and customization of
technologies
Development of varieties for principal crops suitable for agro-ecological
zones and capable to withstand biotic and abiotic stresses
Development, validation and training related to seed production
technologies for principal crops across agro-ecological regions
Formulation of site-specific integrated plant nutrient management
system to augment productivity and to sustain soil health and resilience
at the same time
Formulation of IPM modules across agro-ecological regions for ecofriendly management of pest-disease-weed.
Development and administration of appropriate post-harvest
technologies for fruits, vegetables and other commercial crops for value
addition.
Sensitization and motivation of entrepreneurship for linking producercustomer through producer companies developed with stakeholders
