Climate Smart Seeds

Since civilization farmers, fishers, pastoralists and forest dwellers have been managing genetic diversity by selecting plants and animals to meet environmental conditions and food needs. Such abundant body of priceless knowledge is transferred from one generation to the next. Today we are the beneficiaries of such traditional knowledge on crops, cultivation, storage, processing, cuisine and associated gastronomy.

 Do we really appreciate the tireless efforts of our ancestors?

Unfortunately the monocultures of crops world over has resulted in the monoculture of mind. Large acreage of one crop variety is grown for years and all efforts are put in to encounter the associated problems of monoculture like, loss of fertility of soils, pests and disease outbreaks and reduction in the nutritional value of food.

Food and Agriculture Organization (FAO) of United Nations estimates, about three-quarters of the genetic diversity of agricultural crops have been lost over the last century. An equally important task is to maintain biodiversity on farms, where it can evolve and adapt to changing climatic conditions. As custodians of the world's biodiversity, farmers can develop and maintain native plants and trees and reproduce indigenous animals, ensuring their survival.

Most of the developing countries are blessed with a rich bio-diversity and wide range of agro-ecological zones with great genetic wealth providing opportunities for cultivating a variety of crops and rearing a wide range of livestock. The farmers of poor countries depend on the use of genetic biodiversity for their income and living. Experience and knowledge gained over many generations have made possible the development and conservation of thousands of agricultural crop varieties which otherwise would have been lost forever. Despite the efforts of farmers, there has been a dramatic reduction of biodiversity.

About 10,000 species have been used in food and fodder production world over since the beginning of agriculture. Today just 150 crops feed most human beings and just 12 crops provide 80% of food calories (wheat, rice, maize and potato alone provide 60%).

Low productivity and profitability are the root causes of poverty among farming communities wherein the poor quality seeds and planting materials make the situation still worse. However, large number of poor-farmers all over the world depend on the biodiversity for their livelihood.

Seed is the basic and the most important input in agricultural development. The pace of progress in crop production will, therefore, largely depend upon the pace with which good quality seeds and planting materials are multiplied and easily available to farmers. The time has come now for the farmers to rediscover the ancient wisdom of seed sharing and conservation and be least dependant on the seed companies. The control of seeds should not be in the hands of few organizations who would dictate terms on farmer’s sovereignty. 

How to utilize biodiversity to diversify incomes/livelihoods?

In the present era of changing climate one needs to make smart choices for the selection of cultivars which can adapt to climate change. The hybrid seeds which are bred to yield under ideal conditions of weather, water and fertilizers/pesticides are not a viable solution. Hybrid seeds may be an option for the intensive synthetic agro-chemical based subsidised agriculture but not for poor small famers of the world who contribute more than 75% of the global food requirements.

At present repeated sowing has become a norm due to irregular weather patterns which in fact is a common trend seen nowadays in many regions. This translates into repeated seed purchases by farmers which pushes them into the vicious cycle of debt resulting in a sequel of socio-economic issues.

Moot questions

How can farmers adapt themselves in the changing weather patterns and be least dependant on the expensive seeds?

Is seed production a complex process which farmers cannot comprehend?
Obviously NO.

Farmers can produce their own seeds with basic training on simple practices of seed production like pollination patterns, isolation, seed harvesting and threshing, drying, cleaning, grading, seed treatment and packaging. Seed production on farm is easy by using the time-tested open pollinated seeds. They are also called as heirloom seeds or native seeds or traditional seeds.

Misconceptions of Open Pollinated (OP) seeds

Many people are superstitious about OP seeds and believe that they are low yielding and may not be in a position to feed the hungry mouths. As the dictum “Seeing is believing”, please see the following photographs to falsify the prophets of doom.

Benefits of open pollinated seeds
Open pollinated or traditional/native varieties breed "true to type" and adapt well to low input farming using organic practices. The advantages of open pollinated seeds are many:

i. They  are climate smart approaches for adaptation

ii.  It insures seeds for the small  scale farmers for their next season.

iii. Traditional varieties are not   
  adapted to industrial chemical farming but to small scale farming which rely on crop rotation, crop diversification and systematic varietals mix up of crops from different genetic makeup.

iv.  They are characterized by polygenic resistance to pest and diseases as they are genetically diverse (multi gene resistance) and ensures the farmer against pest outbreak, crop losses, biotic and abiotic stresses.

v. They contain more micro nutrients which combat malnutrition and micro nutrient deficiency in the diet of rural/poor people. They are suited to home gardening which is at the forefront of the struggle against malnutrition and can provide approximately half of the nutritional requirement for the marginalized population.

vi.  Open-pollinated seeds when produced on-farm, or mutually shared, has  
  minimal cost implication on cost of production while conventional and commercial seeds (such as hybrids) can cost the farmers about 30% of their total investment for cultivating a crop.

Seed production is not a rocket technology. Any farmer who has the experience of cultivation of a crop with some basic training on pollination patters of crops can produce their own seeds.

However, development organizations can facilitate the process by building capacities in seed production, selection, breeding and conservation of seeds. In addition there is a need to create awareness highlighting the synergies between genetic resources, nutrition, health, cooking and conservation.

  1. SEEDS are very precious .
    There is something unique about a form of gardening when you reap what you have sown within a week . This is what seed sprouting has to offer.
    Seed sprouting – which is simply germinating seeds and planting / eating the tiny seedlings- usually before they even develop seed leaves – is one of those ideas which go a long way in history. Seeds meant for planting could be planted in special protrays and then planted to pots/mainfield.
    The Aztecs, and Navajo Indians, and the Chinese were all sprouting seeds many centuries ago.
    What can be sprouted? Although we tend to sprout only a few kinds of seeds, surprisingly a large range of seeds can be sprouted. In the bean family apart from the mung bean, there are the beans, broad, French runner, Lima & Soya beans. While other suitable legumes include lentils (whole, not split), clove peas and chick peas. Suitable grains for sprouting are wheat , oats , barley, millet , maize and buckwheat , while suitable brassicas and other crucifers include kale, broccoli, brussels sprouts cauliflower , radish, rape and of course , mustard and cress. The list can be rounded off with a few miscellaneous seeds such as pumpkin, marrow, melon, sunflower and even mint. As so many seeds can be sprouted it is tempting to experiment, but before doing so make sure you have suitable seed.
    Once you have the knack, sprouting becomes second nature and ridiculously easy. But people do have failures, the commonest being seeds going moldy or sour. The secret to remember that germinating requires four things:
    1.Warmth: The average room temperature, 55 to 65 degrees F is generally about right.
    2.Moisture: just moist, not swamped with water or allowed to dry out.
    3.Air: as they need oxygen to breathe and develop.
    4.Clean conditions.
    Failures can usually be traced to being kept too hot or too cold, too dry or too wet, to suffocation by being in too thick a layer or too small a container and to not being rinsed frequently enough. In short, problems stem from the fact that the warm, moist conditions which seeds need to germinate are just the conditions that would favour the development of disease and mould – hence the need to encourage vigorous growth in fresh conditions.
    SPROUTING : There are several ways of sprouting seeds. The essential element is some means of rinsing them with water to keep them fresh.

    It is preferable to sprout the seeds in plastic containers with fitting lids, the sandwich box type of thing. Jam jars with muslin over the top, held in place with a rubber band or even better, with a lid made of tin foil with holes punched in it. A snag with muslin is that it becomes discoloured and small seeds tend to adhere to it. Bowls, and even deep plates, can be used.
    Jars can be upright or placed on their sides to spread the seeds more evenly.
    Sprouting can be done in the dark or in the light, but seeds such as mung and alpatco beans, lentils are whiter and crisper if grown in the dark, but is really a matter of taste. You can darken a jar or dish by covering it with black plastic or tinfoil or standing it inside a slit cornflakes packet.
    Most seed should be ready within five to seven days, though this varies with seed and temperature.
    A modification of this method is to line the container with some kind of base-flannel, cotton wool or several layers of blotting paper – in the time honoured method of growing cress.
    In our experience seeds take longer to sprout when grown on a base, but they are less likely to dry out. In the early stages the seeds can still be tipped into a strainer to rinse them, later on, when they root into the base, it is more a question of pouring water in, swirling it around it gently, and pouring it out Could use again, they grow a little longer than they would otherwise do.
