The achievements of the green revolution have been at the expense of the environment, natural resources, and social justice. The grave consequences of an exploitative use of technology need a therapy combining modern and traditional agricultural technology. Failure to adopt this process of bio-remediation, says Dr. Sankaram Ayala, may mean falling prey to the ‘Asian financial flu’ haunting our doors.

Given the importance of agriculture in general and cereal crops in particular, the green revolution has been a triumph and transformation from subsistence to market orientation of agriculture in this century. It is the incredible yield transformation of staple cereals, rice, wheat and corn. A bio-technological marvel of synergistic interaction of genetics, agronomy and plant protection. The high yielding variety is the starter, with water and fertilizer as the catalysts to translate the genetic yield potential into harvests. Plant protection is the science of controlling field crop losses caused by pests, diseases and weeds. It is based on two scientific processes: assimilation of solar energy in the leaves and synthesising processes of the carbohydrate, fat and protein in the seed. Both are integral parts of the production of yield; and without either, there is no yield

l The first attempts at crop improvement for yields in India in the forties, after World War II, the Grow More Food and Intensive Agricultural Development Programmes were positive but insufficient to convince the farmers. The missing link was a crop variety responsive to fertilizer and water use. After a long and tedious search, the discovery of Taichun Native 1, a variety genetically inclined to profuse tillering without lodging and responsive to fertilizer and water, constituted the vanguard of the battle on the food front. At this time, the Indian food situation turned grave with two successive drought years. Acrimonious debates in Parliament and starvation deaths, led the Minister for Agriculture, C. Subramaniam, to a firm promise in Parliament that he would solve the problem within a period of five years. He redeemed the promise through a visionary and pragmatic policy with five major components:

  • Agriculture that supplies the sinews of development and strength had a management problem and that a productivity approach would help in maximizing output.
  • The fatal fascination for release of crop varieties to suit every taste and flavour needed a shift, to yield-raising inputs and their management to enhance use efficiency (Feb 1964).
  • For exploitation of science and technology in governing crop production, scientists must first demonstrate what they advocate, right on the farmer’s field.
  • A seed bill to be enacted provides for regulation of quantity and quality seed for varieties chosen on the advice of a crop variety release committee (Dec 1964)
  • The Food Corporation of India, (FCI), to be instituted, functions for trade in food grains and covers the interests of the producer, against cyclic and seasonal fluctuations in prices and the consumer from exploitation and the vagaries of speculative trade. The instruments of implementation are the Prices Commission, provision of credit requirements of the farmer in full and a Ware-housing Corporation for storage and distribution of buffer stock of grains. (Jan 1965)

For the technology to be acceptable to farmers, the first step was to demonstrate it right on the farmer’s field, in a national demonstration. For the year 1965, three hundred sixty six demonstrations on five cereals, rice, wheat, sorghum, maize and pearl millet, all over the country, convinced farmers of the merits and feasibility of the technology. (Table 1)

  • Over the years 1975-83, demonstrations were conducted on the HYV technology on the farmers’ fields; the untapped yield potential was 54 per cent.
  • The fertilizer use in terms of kg. per tonne of grain moved from 4.5 to 137 over 30 years with yield rise by a factor 2.5.
  • IFFCO, demonstrated at the APAU (Hyderabad-1986) with the use of only 56 kg N/ha as Super Granule urea, with appropriate P and K recorded a yield of paddy grain 5.2 t/ha and use efficiency of fertilizer at 25.5.

The progress of adoption by natural spread over the years, 1965-85 boggled the imagination of the formulators and implementers. The first peak harvest of 150 mil/t of food grains, symbolised that the battle on the food front was won. Malthus’ foreboding failed and the famines of the past receded. The promise of the Minister for agriculture to the Parliament was redeemed.

The vital lesson to be learnt from the IFFCO experiment is that it is perfectly in line with what was recorded in 1966 by Panse and Abraham (1966) “contrary to the usual belief, application of two nutrients together or all the three nutrients to form a balanced fertilizer has not yielded a response larger than the sum of the responses to individual nutrients and in all the regions of India except the West coast, the combined response is even lower than would be expected on an additive basis”. Having failed to respond to this advice the formulation and promotion of the three nutrient complexes has been the most expensive error in our fertilizer product patterns and their promotion from which the nation and the farmer have incurred and continue to incur incredible losses. This may appear small to the common man and in the context of politically apprehensive attitude towards an industry. It is in reality more than just a cog in the wheel, for fertilizer used to be dysfunctional.

India’s Green Revolution Achievements

Single largest consignment of wheat seed, (Lema Rojo 64) of 18,000 tonnes, freighted by India on July, 18,1966 from Guyman (Mexico) to Kandla (Gujarat, India).

Demonstration of HYV technology right on the farmer’s field that would convince hundreds of the feasibility and profitability, year after year, caused a natural spread. While farmers in the US required ten years for adoption of hybrids, Indian farmers accepted the HYV for rice and wheat over a short period of 5 to 6 years.

The announcement of the political policy in totality and not piece meal for agricultural development in 1965, triggered the green revolution, preceded the implementation.

In 1984, the US promulgated the Food Security Act and Alternative Agriculture. In the same year, India recorded the first peak food grain harvest of 150 mil/t. Since then yields declined or plateaued at a certain level. By 1990, it was realised that plateau yield, was the symptom of a deep-seated malady, characterised by disruption of biological, ecological and social systems.

Bio-remediation of conventional agricultural practices
Conventional agri-practices Bio-remedial measures
Mono culture  Crop rotation, mixed and inter cropping
Chemical fertilizers Combination of inorganic and organic blends, crop-tailored formulations
Chemical pesticides IPM - Integrated Pest Management with chemical pesticide as the last resort.
Water use Conjunctive use of resources and conservation of rain water
Energy - fuel oil based Largely human and animal energy for all cultural operations with no subsidy.
Maximisation of crop yield Organic manures Economic maximisation of yields Use of green manures, enriched compost and tank silt.
Environmental quality Protection of forests, reduction in oil  based fertilizers and mechanisation of cultural operations

Thus:

  • There is anchoring evidence that conventional agriculture for the developing world, particularly for India would prove to be catastrophic.
  • The approach towards agriculture, forestry, animal husbandry and fisheries has been invariably manipulative, short sighted, destructive and degrading.
  • All critical planetary thresholds are crossed or will be, while economic indicators are positive, key environmental indicators - land, water and biodiversity - are increasingly negative.

The green revolution lost its momentum, with the loss of ecological and technological sustainability in both developed and developing countries. The glory of Egypt’s agricultural excellence under the Aswan Dam entered the era of distress for food and fisheries. China was in distress, as the water table of the North Central plain dropped at 1.5 metres per year. Punjab - agricultural centre of India - is under serious threat of nitrate pollution of underground water and expansive salinity.

The truth is that, nothing is wrong with the technology but nothing is right in its implementation on the field. The yield fatigue is the symptom of a deep-seated malady of the total violation of natural laws governing the technology; in particular, the mismanagement of all inputs, as greed over powered need. The thrill turned into a threat, the glamour changed to clamour, a stunning marvel melted into an incurable malady.

The seed industry for food grains and hybrid cotton opened several job opportunities and multiplied fortunes of the adventurous few. Fertilizer manufacturers sparkled financially, while distributors had their expected high share. Expansion of irrigation through dam culture enjoyed ceaseless good fortune along with corruption of global dimensions. Those in the grain trade, between the producer and the consumer, harvested all the cake without sowing anything. All job opportunities under urban development are at the expense of the finite resources and the honest sweat of farmers and labourers. What little profit the HYV technology conferred on the poor farmers passed into the pockets of many unrepentant felons of trade. The incentives to catalyse resource degradation and decreased response to technology are the result of liberal political patronage. The farmer is stripped naked economically and the rural areas impoverished. The rural urban divide is frightening. Poverty is pervasive and hunger deepened, for global statistical records. Like the solar-based photosynthesis, the science of the green revolution is immortal; only greed based human behaviour made it less functional and more destructive. Planned development as we step in to the next century with more of the same kind of inputs and higher energy levels leads us to the grave yard, the place of final peace akin to the adage “The reconciling grave swallows distinction first that made us foes. There all lie down in peace together.”

Traditional farming systems have emerged over centuries of cultural and biological evolution and represent the accumulated experience of farmers in interaction with the environment without access to external inputs, capital, or scientific knowledge. It is wrong to simply equate tradition with superstition, ignorance and illusion. Centuries of experience were rewarding and guided farmers in nearly all areas to develop sustainable agro-ecosystems managed with locally available resources and human and animal energy. Agronomy, the mother discipline of agro-ecology (alternative agriculture) is strongly influenced by the environment. There is no alternative, but to replace monocultures and external energy inputs to a point where further erosion of natural resources is prevented, yet achieving ecologically sustainable yields under economically viable practices. The future of sustainable agriculture carries a trinity of goals: economics, environment and ethics.

The mandate for agricultural development of India, as we step into the next century, must be read as “to produce increasing yields, year after year, from decreasing basic natural resources, to meet the rising demands of an expanding population with shrinking purchasing capacity. At the same time there should be no adverse effects on both the resources and environment.”

The data of distress for the period 1984 to 2000 convincingly warns that this century will end, not on a bright note of optimism, but with a challenge to our latent abilities to apply the corrective therapy. (Table 3) .The troubling triple alliance is the decline in soil fertility, fall in use efficiency of inputs and excessive chemicalisation. All future production must come from soil already under cultivation, not with more inputs of the past kind but through principles of ecological management rooted in the essentials of prudence and use efficiency.

By 1990, it was realised that plateau yield was the symptom of a deep-seated malady

To this end, an appropriate mindset of policy makers and farmers is imperative. But though the politician maintains a stony silence and the farmer displays extreme resilience to poverty, the dawn of Y2K will neither be delayed nor would it function better for the farmer, even if the entire world were democratically governed.

Change in Mind-Set

To develop a forward-looking mind-set and a freshness of approach towards agricultural progress these key elements must be considered:

  • A change in the belief that human beings are the rulers of the world and not subject to the laws of nature is essential.
  • Over the past two decades, man has learnt how to farm with chemicals and large-scale machinery. There is an urgent need to capture the culture of the past traditional wisdom to farm in ecologically sound ways, to preserve the health of the soil, protect the integrity of the environment and promote the use efficiency of scarce resources.
  • Science and technology chosen must be integrated with local traditional practices for economic maximisation of crop yields.
  • A major shift in planning and execution becomes imperative in three areas (a) from crop centred to cropping systems (b) vertical integration to be replaced by horizontal (c) from the totally inorganic to a blend of organic and inorganic.
  • For globalisation to be rewarding, a cross border dialogue, on all issues including patent laws, based on morality, welfare and ethics to be mutually beneficial, sufficiently transparent and highly purposeful for rural development of the recipient country, is crucial.
  • To look beyond yield achievement is imperative and what J. B. S. Haldane observed in his book “Science and Future” (1923) is the warning that, “Unless our ethical outlook evolves to keep pace with the development of science and technology, social chaos and disaster would result”. This would happen to all developing countries if we do not change our conventional agricultural pattern. Developed countries would suffer in a different way with drug abuse and obesity associated with a variety of health problems.

    Agricultural Scenario for the period 1984 to 2000
    Population rise per year (per cent)           2.2
    Production of food grains per year (per cent)        1.8
    Food grain entitlement per capita gm/day 560 to 540
    Change in cereal/protein ratio     3:1 to 6:1
    Rise in procurement price, paddy (per cent)/yr.    10 to 17
    Rise in consumer price rise, (per cent)/yr.            20.0
    Middleman chain profit as per cent of consumer price        40.0
    Farmer’s net profit (per cent of procurement)       35.0
    Fertilizer use efficiency decrease             7.3 to 4.3

  • It is necessary to be aware of where human duty to protect humanity ends and human obligation to Nature begins. To dominate over other living companions and distance ourselves from Nature is fatal.

The green revolution is deemed a unique energetic institution of global dimensions. In India, its success has been limited to the physical supply of grains but, as a means to end hunger and poverty, it has been a failure (Perkins 1997). It is totally and firmly based on science and the indisputable natural laws governing ecosystems. A rejection of the HYV technology on environmental grounds fails, if the greedy and excessive misuse of the resource base is impartially evaluated. In short, there is nothing wrong with the technology and nothing right with its application in the field. If the current (since 1900) levels and patterns of input use, water, fertilizer, pesticides energy and cultural practices are continued with projected escalations for fertilizer and energy (NAASc. 1996) under the only plea of population increase, Malthus’ foreboding will come true. India will be in the cruel grip of Asian Financial flu with civil war in the streets.
