1 Background: The Imperative for a Transformative Shift in Indian Agriculture
-
HEIA: Characterised by high and often excessive consumption and dependence on external inputs; the national average of 133 kg/ha of fertiliser does not reveal the extent to which it leaches into hydrological systems or causes damages to soil biota and soil organic carbon accumulation (DES, 2020). According to DES (2020) over 75% of cropped area has synthetic fertiliser applied to it (ranging from about 78% of small and marginal farmers to about 63% of large land holdings) and about 43% of cropped area is treated with pesticides. Overuse of synthetic inputs in such systems, especially in irrigated systems, is a major contributor to driving land and water degradation, health impacts, farmer indebtedness and a number of other deleterious impacts, as explained above. While annual statistics are available for consumption and production of synthetic external inputs, no such statistics are available on impacts of overuse—a lacuna that needs to be filled. But at the same time these practices provide the bulk of India’s food production, especially staples, oil seeds and certain horticultural crops. There is a growing consensus that these systems need to be made much less dependent on external inputs, much more efficient in their use of inputs. Two pathways are proposed for such transformation: a more capital intensive, external knowledge driven transformation for which terms such as precision agriculture, sustainable intensification etc. are used. This we see as an incremental change to an already relatively capital-intensive system that expects to deliver transformative results based on external injection of knowledge and more built-capital, we will not deal with this type of change here. The second pathway we see as being a more transformative change based on adherence to agroecological principles and knowledge, in order to radically reduce external inputs while sustaining productivity and reducing adverse impacts on the whole system. It relies on restoring or sustaining natural capital, especially contributions from biological diversity, while building on human and social capital at multiple scales and forms. As a result, this second pathway is much less built-capital dependent, as such it seeks to transform a HEIA into a LEIA. In between these lie approaches such as conservation agriculture and regenerative agriculture, which may take either pathway, depending on how they are interpreted.
-
LEIA: These include systems that traditionally depended less on external inputs of any kinds, as well as more ‘modern’ LEIA systems such as organic farming, natural farming, agroforestry etc., which may incorporate external inputs at low intensities. Between LEIA and HEIA we have various forms of regenerative agriculture, permaculture and integrated agricultural systems, although based on their intentions of building on natural capital and minimising external inputs they are also classified as LEIA. Sustainable improvements to LEIA systems would involve improving access and uptake of evidence-based agroecological knowledge, organisation, policy and institutional support, to support better use and delivery of ecosystem services, access to markets and price stability. In other words, the transformation pathway here focuses on strengthening human and social capital, without reducing the important contribution of natural capital, with much less emphasis on built-capital. Although changes proposed would be incremental as the systems remain LEIA, the impacts would, however, be transformational with respect to profitability, productivity, sustainability and resilience of these systems.

2.2.4 Organic Farming and Other Approaches
Government of India has elucidated its recommendations on how to implement organic farming (NHM, undated).Organic agriculture is a holistic production management system which promotes and enhances agroecosystem health, including biodiversity, biological cycles and soil biological activity. It emphasises the use of management practices in preference to the use of off-farm inputs, taking into account that regional conditions require locally adapted systems. This is accomplished by using, where possible, agronomic, biological and mechanical methods, as opposed to using synthetic materials, to fulfil any specific function within the system.
2.3 Designing Transformation Processes
-
Conventional (and now biotechnology-enabled) breeding programmes focus on bridging yield gaps in monocrop fields. In the hot, dry conditions of arid zones of the Sahel, there is overwhelming evidence that cereal crops like maize, millet and sorghum grow better under the shade of trees like Faidherbia albida than they do under the open sun. In arid Rajasthan, increases in the amount of nitrogen and phosphorus and other macro-and micro-nutrients are reported under Khejri (Prosopis cineraria) as compared to sites bare of vegetation (Shankarnarayan, 1984), and forage species produce higher biomass under khejri tree canopy due to a high fertility status (Singh & Lal, 1969). And yet breeding programmes simply ignore the opportunities of breeding for ecological synergy, despite the obvious adaptation benefits.
-
Although it is clear that soil biota play an enormous role in determining the fertility and indeed sustainability of farmers’ fields, instead almost all the research on improvement of fertility is focused on fertiliser inputs.
-
With respect to the relation of agriculture with food systems, applied research about agricultural, or global, value chains would pay particular attention to governance, in helping to elucidate the balance of power, decision-making and access to information among the different actors in food systems, from producers/farmers to consumers, as well as to efficiency in terms of identifying market opportunities (Béné et al., 2019).

3 What India Needs to Achieve by 2030
-
Ensuring that the welfare and advancement of farmers and food system actors meets expectations: Even using the rather limited indicator of cash income, it is apparent that income earned by a farmer from agriculture is crucial to address agrarian distress (Chand et al., 2015; Chand, 2016) and so any transformation of the system must promote farmers’ welfare and at least meet expectations of parity between income of farmers and those working in non-agricultural professions.
-
Better access to quality seeds and planting material, along with improvements to supply chains for these. It is estimated that the direct contribution of quality seed alone to the total production is about 20–25% (http://seednet.gov.in) depending upon the crop and it can be further raised up to 45% with efficient management of other inputs. This includes judicious exploitation of hybrid technology, because managed well and in the appropriate circumstances, hybrids are a powerful ally for transformation of food systems, especially if the benefits are extended to so-called orphan crops. In this context biotechnology too has a great potential in improving efficiency and profitability of agriculture through identification of promising varieties of under-invested crops, disease resistant planting material, hybrid seed production, rapid and accurate diagnosis of diseases, rapid breeding of new varieties, etc. Recently 35 crop varieties developed by the Indian Council of Agricultural Research (ICAR) to address the twin challenges of climate change and malnutrition were released. These climate-resilient crops include a drought tolerant variety of chickpea, wilt and sterility mosaic resistant pigeon pea, early maturing variety of soybean, disease resistant varieties of rice and biofortified varieties of wheat, pearl millet, maize and chickpea.
-
Capacity and capability strengthening: This is especially true in research, rural advisory services and outreach for hitherto neglected crops and farming systems that are more climate resilient and benefit farmers and consumers. The paradigm for education, training and research must shift from being top-down and productivity driven to being inclusive also of farmer innovation and systems resilience driven. Indeed a salient feature of any sustainable agriculture system of the future will be its ability to support innovation that drives context specific adaptation in the face of drivers of global change that are only picking up momentum.
-
Shifting to better adapted species and practices: The development and identification of disease resistant and climate resilient crops and crop varieties, with enhanced tolerance to fungal/insect attack, heat, drought, flooding, chilling and salinity stresses are essential in order to sustain and improve crop yields to cope with the challenges of biotic/abiotic stresses. Similarly, as biofertilisers are emerging as means for reducing chemical footprints in agriculture, the biopesticides have huge role to play in sustainable management of crop pests and pathogens. ICAR developed 41 validated biofertilisers and 31 microbial formulations were made available to farmers of the country in recent years.
-
Shifting to more resilient forms of agriculture that still meet productivity thresholds: such as agroforestry, horticulture, permaculture, natural farming and other agroecological approaches. An expansion of horticultural crops, for example, allows for resilient growth that takes advantage of India’s long growing-season, diverse soil and climatic conditions comprising several agroecological regions, and can be particularly impactful in farming systems that build on diversity, such as agroforestry and permaculture. The potential contribution of horticulture has been recognised in the report of the committee on doubling farmers income (DACFW, 2018). Between 2000 and 2016, horticulture growth rates of 5.8% occurred owing to technological back-up, investment and policy environment. Past trend shows that target of production of 316.41 million tonnes envisaged for 2020–21 is easily achievable, as production of 314.67 million tonnes has already been achieved in 2018–19.
-
Managing agricultural landscapes for more than food production: This will require developing new metrics for evaluation of impacts and effects, valuing and supporting diversity in farming systems, protecting soil fertility and its regeneration through the farming system, promoting cyclical agriculture and bioeconomy and reforming agriculture research and education (Table 4).Table 4The major targets for change and notional difficulties in achieving them depending on starting conditionsTarget for changeRelative degree of difficultyHEIALEIAShifting to farming systems that are better adapted and adaptive to climate change, based on agroecological principlesVariableLow to mediumDiversification including towards higher value and higher nutrition content cropsHighLow to mediumImproving tree cover, biomass and soil-organic carbon and fertility across Indian agricultureMedium to HighLow to mediumConcomitant improvement in productivityMediumMediumResource use efficiency especially with respect to waterMedium to HighLow to mediumIncrease in cropping intensityMediumHighLandscape approach that factors in contributions from forests, common lands and waste-lands in the provision of ecosystem servicesMedium to HighMedium to highShifting cultivators from farm to non-farm occupations, andHighLowImprovement in terms of trade for farmers or real prices received by farmersHighHighBasing policies and investments on a full or true-cost accounting approachHighHigh
