Biodiversity and traditional
seeds are being rapidly lost in all countries of the world. The reason for this
erosion of genetic diversity is the promotion of intensive agriculture relying
overwhelmingly on high yielding varieties. The Green Revolution is the greatest
culprit for genetic erosion. Government policies while actively promoting the
Green Revolution, paid little attention to the conservation of traditional
seeds even though the two could have gone hand in hand.
Nevertheless there are many
farmers in developing countries that still cultivate traditional varieties,
though they too are shifting to high yielding varieties when they get a chance.
Farmers in rainfed areas, marginal lands not suited to intensification or
special eco niches like regions with brackish water, such as the Sunderbans,
continue to rely on traditional varieties.
Such farmers maintain a number of
different varieties of many crops, including staples like rice. India
which is the birth place of rice was once home to almost 200000 varieties, with
a range of different properties. Farmers maintained these because they provided
a choice of seeds to cope with different weather conditions like the timing of
the monsoon, type of soil, location of the farm etc.
Apart from farmers who maintain
traditional crop varieties because it helps them adapt to local ecosystems and
weather conditions, there are also those who maintain a diversity of cultivars
out of pure interest and passion. Called “Custodian Farmers”, these are the
real seed saviors. They develop & maintain
agricultural biodiversity and also share this with other farmers. These
seed saviors are high on skills and unlike the farmers who practice intensive
agriculture, they are knowledgeable
about their varieties and know how and where these cultivars can be adapted.
Farmers who conserve a variety
of seeds automatically become an integral part of the informal seed system
since with their knowledge, they can recommend
varieties for specific conditions. They are aware of local preferences and
promote the conservation and use of local diversity among their friends and neighbors
for the sheer joy of it. Such sharing of seeds and planting material like
cuttings, runners, buds and grafts is
not monetized within the locality although planting material may be made
available to outsiders for a price.
The fruit orchards, especially
of mangoes, belonging to the landed aristocracy were a treasure trove of
diversity. Mangoes of different colors and shapes, tastes and aromas have been
conserved in these orchards for generations. The saviors and keepers of this
diversity were more the orchard keepers and gardeners than their masters.
Seed saviors are found in all
kinds of agro ecosystems, usually in tropical countries where they are conserving
seeds of all kinds of cereals, fruits and vegetables. Now, the trend to save
old varieties is becoming increasingly popular in the industrial countries too as
people have become wary of the consolidation of the seed industry in the hands
of a few companies. These companies armed
with seed patents are pushing a few commercially popular varieties, neglecting
the rest. Seed saver networks have sprung up in Europe and the USA,
most specializing in the conservation of heritage seeds which are the older
varieties that have fallen into disuse.
National and International Seed
Saviors
Not just individual farmers and
communities, a chain of national and international gene banks have been
established as global seed saviours. For example, the International Rice
Research Institute (IRRI) in Los Banos , Philippines
conserves all the rice varieties of the world, as Cymmit in Mexico does for
wheat. The International Center for Agricultural Research in the Dry Areas
(ICARDA) conserves over 135,000 seed samples of wheat, barley, oats and other
cereals; food legumes such as faba bean, chickpea, lentil and field pea; forage
and rangelean crops, as well as the wild relatives of each of these species.
Similarly ICRISAT (International Crops Research Institute for the Semi-Arid
Tropics) in Hyderabad saves several thousand seed samples of chickpea,
pigeonpea, ground nut, pearl millet, sorghum and little millets.
Svalbard
The world’s most dramatic seed
saving set up, atleast its most talked
of, lies in the Norwegian town of Svalbard ,
north of the Arctic Circle. Often referred to
as the ‘Doomsday Vault’, the Svalbard seed
bank is supposed to protect the world’s seed collection from the most terrible
disasters that can befall , hence the name “Doomsday Vault’. The Svalbard bank
as it is planned will eventually conserve a sample from all the collections
currently housed in more than 1400 gene banks across the world. The reasoning
is that if disaster strikes any one or more of the banks, the seed material
will not be lost since it will be backed up in the bomb proof bunker built some
400 feet inside a Norwegian mountain covered in permafrost.
Chang La
To match the effort in Europe, Indian authorities are going ahead with the
construction of a similar permafrost gene- seed bank in Chang La in Ladakh. At
a height of over 17,500 feet, The Chang La gene bank is about 75km from Leh and
is under the stewardship of the Defense Institute of High Altitude Research.
Intended to be a national conservation centre initially, it is proposed to make
available the Chang La gene bank for the seed collections of developing and
developed countries. Chang La's permafrost conditions, low humidity and temperatures generally below -
18 degrees Celsius are ideally suited to conserving seeds at low temperature
without the energy costs.
More than apocalyptic
calamities like cyclones, hurricanes or bombs , the world’s genetic material
and its seeds are threatened steadily by a warming planet and consequent change
in the climate. So saving seed collections in Svalbard
and Chang La is of great significance.
Gene Campaign as Seed Savior
In 2008, Gene Campaign along with the farmers that
it works with in Jharkhand, received India’s Genome Savior Award. This
award recognizes seed saviors, those who conserve traditional seed varieties.
Gene Campaign has been working in Jharkhand and Uttarakhand for the last
several years, conserving traditional varieties of rice, millets, legumes,
vegetables and oilseeds. A special focus is the conservation of rice since India is its Center of Origin
and the place where the greatest genetic diversity of rice is found.
Traditional crop varieties from farmer’s fields
are collected and the knowledge of the farm family is documented along with the
seed sample. The Gene Campaign
collection consists of about 900 rice varieties from Jharkhand, Orissa,
Chattisgarh, West Bengal and Assam.
The seed samples are scientifically processed and conserved in community
managed, field level gene-seed banks.
Zero Energy Gene Seed Banks
Unlike the cold gene banks of
the formal system, Gene Campaign’s , Zero Energy Gene Seed Banks have no energy costs. Because
these banks are located in the village,
they are owned by the people. Village youth committees supervised by village
elders run the banks.. The seed in the bank is accessed every season by the
farmers who return three times the seed they take, when their harvest comes in. The core
collection is multiplied in carefully designed plots in farmers’ fields,
monitored by trained village youth and Gene Campaign staff.
Seed renewal to maintain viability
Viability of the seeds is
maintained by growing them out each year and returning the fresh seed to the
Banks. This routine exposes the varieties to the current climate, helping them
to adjust and adapt. The seed material that is returned to the bank after every
grow-out season is adapted to the environment, which includes the climate as
well as pests and disease. The material frozen in the cold gene bank does not
get a chance to adapt to the local climate and when it is taken out at a time
of crisis, it may or may not have the adaptive capacity to provide an efficient
crop under the prevailing conditions.
In the short term the Gene-Seed banks serve
as a seed source for farmers who can access seed adapted to local conditions.
They are also a repository of Farmer Varieties, which are being registered with
the National Plant Variety Authority.
Seed Saviors are specialists
Rather than just conservers of
diversity, many farmers who conserve traditional seeds and planting materials,
see themselves as specialists and tend to conserve varieties with unique
traits. It is a good thing they are recognized as leaders by their communities
and accorded the respect that they deserve. It is high time the scientific
community accorded them similar respect and provided them a place in decision
making about agriculture and the direction it should take.
If the formal system can find
the wisdom to support the women and men that conserve special genetic
diversity, it could become the beneficiary of immense wisdom and a cornucopia
of genes that will keep food production viable in the face of all kinds of
challenges. It will also make our food baskets rich and diverse and make
available to us an assortment of delicious and nutritious foods.
Rightly said. it totally agree with you. their organic ways has always been helpful and they know the actual value of their land and people.
