Agriculture
has evolved since the dawn of civilization, first as a mean to
guarantee food supply , and then, as a source of family income
& improved profitability and finally becoming
the back bone of economies of both Punjab and India. It
still needs to evolve further as so far the emphasis has been more
on Productivity than on sustainability. The present scenario
however, warrants that development
planning has to be based on carrying capacity so as to link
social expectation with ecological capabilities or in other words
ensure economic efficiency coupled with long term sustainability of natural resources base of Punjab
.In Punjab, agriculture is started suffering from various
limitation like reduced land and water availability, constraints
associated with conventional breeding
and increased soil, water, and air quality deterioration
due to intensive use
of farm chemicals.
In
this scenario, biotechnology is fast emerging as a very powerful
technological force well poised to offer inputs, which can go
along way in bringing about a balance between agriculture and
environment
Biotechnology
in agriculture refers to the techniques that allow scientists to
modify DNA, the genetic material of crop plants and livestock, to
enhance their tolerance to pests and diseases, increase yield and
improve quality and nutritional value.. It has a wide range of
possible applications in agriculture and food. Biotechnology can
also bring many benefits to medicine, the environment and
industry.
In
India , there is great scope for agri-biotech inputs
and products. During 1999, the actual
consumption of agri-biotech Products including seeds in
India has been to the tune of 25670 million rupees, it is expected
to rise to 28880 million rupees in 2005 and 78720 in 2010.There
are about 50 private Indian seed companies and about 400
organization doing commercial research on Agriculture. As regards
R&D leads in the country , the transgenics of rice, brassica,
moong , bean , pigeonpea, potato, tomato, cabbage and cauliflower
etc. would be completing field assessment and some of them would
be ready for large scale production by 2005.Transgenic wheat with
more protein content, better quality and also higher lysine
content and marker assisted breeding programme are expected to be
introduced within next 2-3 years. The work on development of
edible vaccines by incorporation of an expression gene in tomato, cabbage, and banana is in progress
particularly for cholera, rabies and hepatitis B. This has
significant implication foe developing countries like India where
immunization against common diseases is difficult and expensive.
Hence, genetic modification of crops for production of edible
vaccines could make a major difference in time to come.
March
26, 2002, marked the beginning of an era in Indian agriculture.
That day the government gave the green signal for the
commercialisation of the first transgenic, or genetically
engineered crop (GEC). It comes in the form of hybrid Bt-cotton, a
transgenic cotton variety resistant to American Bollworm (Helicoverpa
armigera), which is known to destroy over 50 per cent of the crop
in India. The Indian transgenic cotton hybrid has been
developed by the Maharashtra Hybrid Seeds Co. Ltd. (Mahyco), a
Mumbai-based private company, using the genetically engineered
insect-resistant cotton seed and the technology obtained from the
American multinational Monsanto Inc.
The
approval for the commercial release of Mahyco's Bt-cotton was
given by the Genetic Engineering Approval Committee (GEAC) of the
Ministry of Environment and Forests (MoEF), the statutory body set
up for approving large- scale (research or commercial) use of
genetically engineered organisms (GEOs) following the rules
enacted in 1989 under the Environment Protection Act (EPA), 1986.
India is now one of the 16 countries where commercial plantation
of GECs is permitted.
Punjab's
farmers have turned, in recent years, to cash crops such as
sugarcane and cotton. The first never quite took off because of
depleted groundwater and the second is doomed for attacks by the
dreaded American bollworm. Cotton production in the state is down
to 700,000 bales in 2002 from a peak of 2.7 million bales and,
according to reports by deppt. According to Punjab Govt. no less
than 600 indebted farmers committed suicide in Punjab the
year 2002 following cotton crop failure. It is against this
backdrop that Bt cotton, or cotton genetically spliced with toxic
genes borrowed from the Bacillus Thuringiensis (Bt), a bacterium
that is deadly to the bollworm, enters the picture
The
cotton of Punjab which once made it a hero in the country has now
virtually ruined the economy of cotton growers of the state.
Punjab used to boast of its highest yield level of over 600 kg of
lint per hectare which was three times our national average and
slightly better than world average for this crop. Such a pride of
place for cotton is a thing of the past because our cotton
production has been gradually decreasing for the past couple of
years with all-time low of 180 kg/hac in 1999. Such a frustrating
situation has primarily been created by unexpectedly high
incidence of bollworms, especially the Helicoverpa or American
sundi. About 50 per cent of all the agro-chemicals are being used
on the cotton crop alonein Punjab . It is but natural that under
regular exposure to insecticides, the insects are likely to
develop resistance to insecticides rendering even these poisons
ineffective. Dismayed over this failure of insecticides the cotton
growers started making excessive use of pesticides in terms of
higher dose and frequency of spray interval. But even with 3-4
times higher than recommended use of pesticides the bollworms
continue to devastate the cotton crop as a result of which cotton
growers have lost faith in chemical control of insects. In such a
situation every farmer will be surprised if somebody talks about a
variety which does not require any spray and he would jump to
purchase such a variety.
Realising
the importance of biotechnology for the sustenance of agriculture
in the state, the Punjab Government has set up a 17-member
Biotechnology Council, besides seeking to involve top experts to
facilitate the quick transfer of biotechnology for the immediate
benefit of the farm sector. The Green Revolution appears to have
turned sour as the state does not have much of either
biotechnology or agro industry. The state government has already
approved an integrated approach for the practical application of
biotechnology in agriculture by bringing together the farmer and
industry.
The
state now proposes to set up an institute for excellence in
biotechnology with the support of the Department of Biotechnology
of the Union Government by coordinating research activities in
various institutions, including Punjab Agricultural University,
Guru Nanak Dev University, Panjab University and the Institute of
Microbial Technology
The
linkage between the farm and industry will be provided through the
All-India Biotechnology Association. To facilitate the
biotechnology industry, the state government now proposes to offer
a suitable piece of land for a biotechnology park at Anandgarh.
Besides inviting private industry, public sector undertakings and
boards like Markfed, the Punjab Agro Industries Corporation, the
Punjab Mandi Board and even the Department of Agriculture will be
involved in an attempt to catalyse the biotechnology revolution in
the state.
Another
redeeming feature has been the proposed development of an
integrated project with the support of the World Bank for the
cultivation of vegetables and other crops in a specified area in
consultation with Punjab Agricultural University. It was decided
that private industry would fund this project. The land for the
project is to be identified by PAU where farmers will be provided
with the best quality of seed and inputs with a buy-back
guarantee. The Punjab Biotechnology Council, in consultation with
the Department of Food Processing and the Department of
Biotechnology, the World Bank and the Biotechnology Association,
proposes to set up a demonstration project for catalysing the
process of diversification of the cropping pattern to vegetables.
The
biotechnology benefits
to agriculture include :-
Improving Crop Yield
Genetically
improved plants (GIPs) have been developed to be more tolerant to
disease, weeds insects, and drought and be able to grow in
difficult environmental conditions. Considering the devastating
impact of pests, weeds and disease on yields, the agronomic and
economic benefit when plants have built in tolerance is
enormous.Increasing a crop's yield enables us to use less land to
produce the same amount or more food. This also allows us to
preserve other lands such as native forests and delicate
ecosystems for the benefit of the environment and wildlife.
Without increasing crop yields more and more non-arable land will
be brought into production to feed the growing population. In many
cases, this land is unsuitable for long term cultivation and its
use will result in environmental degradation, or the destruction
of the few remaining wild lands and native forests.
Less
Chemical Usage
Biotechnology
can also help farmers reduce the amount of pesticides they need to
use on crops. For instance, by making crops tolerant to a specific
herbicide, weeds can be killed without damaging the crop. The
amount of herbicide used per acre of crop can also be reduced
relative to regular practices. Insect-tolerant crops not only
reduce the volume of insecticide sprayed but also encourage
natural and biological control by not affecting the beneficial
insects. Insect-tolerant crops can form the basis of extremely
effective Integrated Pest Management practices.
Improved
Food Quality
Biotechnology
can give our food improved quality characteristics. Scientists
have the ability to improve the taste, appearance and the
nutritional quality of fruits and vegetables.Another advantage
created by biotechnology is genetically improving the gene
responsible for ripening. For example, delayed-ripening tomatoes
reduce the waste that occurs during transport. In some countries,
up to 20% of fresh produce is destroyed on the way to market due
to unsuitability of these crops for transport. In India, where the
food transportation sector is not completely developed and huge
losses occur, delayed-ripening fruits and vegetables would benefit
consumers living far from agricultural areas.
Environment
Friendly
Among
the environmental benefits of biotechnology is a reduction in the
use of pesticides and herbicides, the prospect of more food
production from the same unit of land and more nutritious food
produce. In addition, scientists have developed methods utilizing
biotechnology to clean up pollution (bioremediation), caused by,
for instance, oil spills.
