 Abstract
Sustainable agriculture is farming in sustainable ways meeting society's present
food and textile needs, without compromising the ability for current or future
generations to meet their needs.It can be based on an understanding of
ecosystem services. There are many methods to increase the sustainability of
agriculture. When developing agriculture within sustainable food systems, it is
important to develop exible business processes and farming practices.
Agriculture has an enormous environmental footprint, playing a signi cant role in
causing climate change (food systems are responsible for one third of the
anthropogenic greenhouse gas emissions),water scarcity, water pollution, land
degradation, deforestation and other processes ;it is simultaneously causing
environmental changes and being impacted by these changes. Sustainable
agriculture consists of environment friendly methods of farming that allow the
production of crops or livestock without causing damage to human or natural
systems. It involves preventing adverse effects on soil, water, biodiversity, and
surrounding or downstream resources, as well as to those working or living on
the farm or in neighbouring areas.

 Chapter 1: Introduction to sustainable Agriculture

Sustainable agriculture o ers a much-needed alternative to conventional input-intensive

agriculture, the long-term impacts of which include degrading topsoil, declining
groundwater levels and reduced biodiversity. It is vital to ensure India’s nutrition security
in a climate-constrained world.While various de nitions of sustainable agriculture exist,
this study uses agroecology as a lens of investigation. This term broadly refers to less
resource-intensive farming solutions, greater diversity in crops and livestock, and
farmers’ ability to adapt to local circumstances.Sustainable agriculture is far from
mainstream in India, with only 5 (crop rotation; agroforestry; rainwater harvesting;
mulching and precision) SAPSs scaling beyond 5 per cent of the net sown area.Most
SAPSs are being adopted by less than ve million (or four per cent) of all Indian farmers.
Many are practised by less than one per cent.Crop rotation is the most popular SAPS in
India, covering around 30 million hectares (Mha) of land and approximately 15 million
farmers. Agroforestry, mainly popular among large cultivators, and rainwater harvesting
have relatively high coverage - 25 Mha and 20-27 Mha, respectively.Organic farming
currently covers only 2.8 Mha — or two per cent of India’s net sown area of 140 Mha.
Natural farming is the fastest growing sustainable agricultural practice in India and has
been adopted by around 800,000 farmers. Integrated Pest Management (IPM) has
achieved a coverage area of 5 Mha after decades of sustained promotion.

 Chapter2: Precision Agriculture
Precision agriculture (PA) is the
science of improving crop yields
and assisting management
decisions using high technology
sensor and analysis tools. PA is a
new concept adopted throughout
the world to increase production,
reduce labor time, and ensure the
e ective management of fertilizers
and irrigation processes. It uses a
large amount of data and
information to improve the use of agricultural resources, yields, and the
quality of crops . PA is an advanced innovation and optimized eld level
management strategy used in agriculture that aims to improve the
productivity of resources on agriculture elds. Thus PA is a new advanced
method in which farmers provide optimized inputs such as water and
fertilizer to enhance productivity, quality, and yield .It requires a huge amount
of information about the crop condition or crop health in the growing season
at high spatial resolution.

Major components of Precision Agriculture

• Data Management and Analytics: At the core of precision farming is a data-driven approach. It involves
gathering data from diverse sources like soil sensors, weather stations, and satellite imagery. Then, through
advanced analytics, this data is transformed into invaluable insights. These insights guide decisions on
planting, irrigation, fertilization, and pest control, optimizing resource usage and crop health.

• Global Positioning System (GPS): GPS technology revolutionizes farming by allowing precise tracking and
mapping of equipment in the eld. This level of accuracy minimizes overlaps in farming activities,
streamlines operations, and ensures e cient resource utilization, ultimately boosting productivity.

• Remote Sensing: The deployment of remote sensing tools, such as drones and satellites, empowers
farmers with real-time information about crop health, soil conditions, and potential pest infestations. These
technologies enable early issue detection, targeted interventions, and improved crop yields, all while
managing resources more e ectively.

• Variable Rate Technology (VRT): VRT is a game-changer, permitting the precise application of
inputs like fertilizers, pesticides, and irrigation. These applications are tailored to the speci c
requirements of di erent areas within a eld, preventing resource overuse and reducing the
environmental footprint of farming.

• Variable Rate Irrigation (VRI): VRI systems are water-saving champions. They dynamically adjust
irrigation rates and locations based on speci c moisture needs within a eld. By doing so, they
reduce water wastage and contribute to the conservation of this precious resource.

• Decision Support Systems: These systems are like trusted advisors for farmers. They provide
recommendations for various farming practices, including crop selection and planting dates,
based on historical and real-time data. They are a compass guiding farmers toward more informed
decisions and better outcomes.

 Chapter 3: Agroecology
Ecology is the study of relationships between
plants, animals, people, and their environment -
and the balance between these relationships.
Agroecology is the application of ecological
concepts and principals in farming.
Agroecology promotes farming practices that;
Mitigate climate change - reducing emissions,
recycling resources and prioritising local supply
chains.Work with wildlife - managing the
impact of farming on wildlife and harnessing
nature to do the hard work for us, such as pollinating crops and controlling
pests.Put farmers and communities in the driving seat - they give power to
approaches led by local people and adapt agricultural techniques to suit the

Bene ts of agroecological practices:

Enhanced Soil Fertility and Water Retention: In rainfed regions of India, traditional
agroecological practices such as mixed cropping and intercropping increase plant diversity and
root exudates, which improve soil structure and nutrient cycling.
Intercropping pearl millet with legumes in rainfed areas of Andhra Pradesh and Karnataka, as
studied by the National Academy of Agricultural Sciences, demonstrated enhanced soil fertility
and water retention.
Integrated Nutrient Management: Agroecological practices promote the use of organic manures,
crop residues, and cover crops, reducing the reliance on synthetic fertilizers and minimizing
nutrient runo .
Research by the Indian Council of Agricultural Research (ICAR) in Punjab demonstrated that
incorporating crop residues and applying compost improved soil organic carbon content,
nutrient availability, and water-holding capacity.
Crop Rotation and Diversity: The practice of crop rotation and mixed cropping improves soil
biodiversity, reduces pest and disease pressure, and promotes e cient nutrient utilization.
Integrated Pest Management (IPM): Implementing IPM techniques such as trap cropping and
biological control reduces the need for chemical pesticides, preserving soil health and minimizing
environmental pollution.
Studies conducted by the Centre for Sustainable Agriculture (CSA) in Andhra Pradesh
demonstrated that IPM practices reduced pesticide use and improved soil microbial diversity,
leading to better soil health.
Organic Matter Enrichment: Practices such as composting and mulching increase organic matter
content in soil, improving its structure, water retention, and nutrient-holding capacity.
A study conducted by the Indian Agricultural Research Institute (IARI) found that organic farming
practices can lead to a 20-30% reduction in greenhouse gas emissions compared to
conventional practices.
Climate Adaptation and Mitigation: Agroecological systems promote crop diversi cation and
varietal selection, reducing vulnerability to climate impacts like droughts and oods.
Example: In Maharashtra, India, farmers are shifting from water-intensive crops to drought-
resistant crops like millets, adapting to changing climate conditions.
Enhanced Carbon Sequestration: Agroecological practices increase carbon sequestration in
soils, contributing to climate change mitigation by capturing atmospheric carbon dioxide.
Example: Agroforestry systems in Tamil Nadu, India, integrate tree plantations with crops,
contributing to carbon sequestration while providing economic bene ts.

 Chapter 4: Vertical Farming Innovations
Vertical farming is the practice of growing crops in vertically and horizontally
stacked layers. It often incorporates controlled-environment agriculture,
which aims to optimize plant growth, and soilless farming techniques such
as hydroponics, aquaponics, and aeroponics. Some common choices of
structures to house vertical farming systems include buildings, shipping
containers, underground tunnels, and abandoned mine shafts.The main
advantage of utilizing vertical farming technologies is the increased crop
yield that comes with a smaller unit area of land requirement. The
increased ability to cultivate a larger variety of crops at once because crops
do not share the same plots of land while growing is another sought-after
advantage.

Chapter 5: Soil Health Management

Soil management encompasses a number of strategies used by farmers and
ranchers to protect soil resources, one of their most valuable assets. By
practicing soil conservation, including appropriate soil preparation methods, they
reduce soil erosion and increase soil stabilization. These soil conservation
methods allow for healthy soil formation, soil fertility and favorable soil
composition, including soil permeability and soil
porosity, which lead to increased soil health. Soil
organic matter is a critical component of soil
health. Cover crops can help maintain or increase
soil organic matter. By using a variety of soil
management practices, soil organic matter will
increase while soil erosion will decrease, keeping
soil nutrients on the farm. Farmers typically use a
soil analysis, or soil sampling procedure, to
determine what inputs are needed. Key practices
include composting, soil chemistry, nutrient
mineralization, soil quality/health, organic matter, cover crops, green
manures, soil analysis, soil microbiology, soil physics.
 Chapter 6: Water conservation techniques
Agricultural water management include a large range of technical, infrastructure,
economic and social factors. Irrigated
agriculture is protected to some extent
from natural variability by hydraulic
infrastructure, but the sector uses a
major share of the available water
resources in the world. Agriculture water
needs must be supplied in a context of
diminishing availability, due to
environmental awareness, population
growth, economic development and
global change. As a consequence, water
management for agriculture is inter-
related not only to traditional water
resources management, but also to food production, rural development and
natural resources management.
Climate change will add to the many economic and social challenges already

Chapter 7: Community Supported agriculture

Community-supported agriculture (CSA model) or crop sharing is a system that

connects producers and consumers within the food system closer by allowing the
consumer to subscribe to the harvest of a certain farm or group of farms. It is an
alternative socioeconomic model of agriculture and food distribution that allows the
producer and consumer to share the risks of farming. The model is a subcategory of
civic agriculture that has an overarching goal of strengthening a sense of community
through local markets. Community-supported agriculture can be considered as a
practice of Commoning. It is an example of community-led management of the
production and distribution of goods and services.
 Chapter 8: Aquaponics Systems

Aquaponics is a unique farming method that

combines aquaculture, the practice of raising
sh, with hydroponics, the method of growing
plants in a soilless environment. In an
aquaponics system, sh and plants are
cultivated together in a symbiotic environment
where they mutually bene t from each other’s
presence. The sh produce waste, which is
converted by bene cial bacteria into nutrients
that plants can absorb. In turn, the plants lter
and purify the water, creating a healthy
environment for the sh. This closed-loop
system is highly e cient, using signi cantly less
water than traditional farming methods and eliminating the need for chemical fertilizers.

Types of Aquaponics Systems

1. Media-Based Systems

In media based systems, plants are grown in a bed lled with a growing medium such as
gravel, clay pebbles, or lava rock. The media provides support for the plants and acts as a
bio lter, hosting bene cial bacteria that convert sh waste into nutrients. Water from the
sh tank is pumped through the grow bed, where it is ltered by the media before
returning to the tank. Media-based systems are simple to set up and ideal for beginners

.2. Nutrient Film Technique (NFT) Systems

NFT systems involve growing plants in channels where a thin lm of nutrient-rich water
ows over the roots. The water is pumped from the sh tank into the channels and then
ows back into the tank. This method ensures that plant roots receive a constant supply of
nutrients and oxygen. NFT systems are e cient and suitable for growing leafy greens and
herbs but may require more precise monitoring of water ow and nutrient levels.

3. Raft System

Also knows as Deep Water Culture (DWC). In this system plants are grown on oating rafts
with their roots submerged directly in nutrient-rich water. The water is continuously
circulated between the sh tank and the plant raft, ensuring a steady supply of nutrients
and oxygen.Raft systems are highly productive and can support a wide variety of plants,
making them popular for both home and commercial use.Understanding these di erent
types of aquaponics systems can help you choose the best one for your needs, whether
you’re looking to start a small home garden or a larger scale farm.

 Chapter 9 : Organic Farming Practices
Organic farming can be de ned as an agricultural process that uses biological
fertilisers and pest control acquired from animal or
plant waste. Organic farming was actually initiated
as an answer to the environmental su erings
caused by the use of chemical pesticides and
synthetic fertilisers. In other words, organic farming
is a new system of farming or agriculture that
repairs, maintains, and improves the ecological
balance.n organic farming, no expensive fertilisers,
pesticides, or HYV seeds are required for the
plantation of crops. Therefore, there is no extra
expense.With the usage of cheaper and local inputs, a farmer can make a good
return on investment.There is a huge demand for organic products in India and
across the globe, which generates more income through export.As compared
to chemical and fertiliser-utilised products, organic products are more
nutritional, tasty, and good for health.The farming of organic products is free of
chemicals and fertilisers, so it does not harm the environment.

Chapter 10 : Biotechnology in Agriculture

Agricultural biotechnology, also known as agritech, is an area of agricultural

science involving the use of scienti c tools and techniques, including genetic
engineering, molecular markers, molecular diagnostics, vaccines, and tissue
culture, to modify living organisms: plants, animals, and microorganisms.Crop
biotechnology is one aspect of agricultural biotechnology which has been
greatly developed upon in recent times. Desired trait are exported from a
particular species of Crop to an entirely different species. These transgene
crops possess desirable characteristics in terms of avor, color of owers,
growth rate, size of harvested products and resistance to diseases and pests.

 Chapter 11 : Limitations of Sustainable Agriculture in India

High Labor Demand: Sustainable agriculture often requires more manual labor
than conventional agriculture, as it involves practices such as Crop Rotation,
Intercropping, Organic Fertilization, and pest management.This can increase
the cost of production and reduce the pro tability of farmers.

Time Consumption: Sustainable agriculture also takes more time to implement

and show results than conventional agriculture, as it relies on natural processes
and gradual improvements.
This can discourage farmers who need immediate returns and face uncertainties
such as weather, market, and policy changes.

Limited Production Potential: Sustainable agriculture may not be able to

meet the growing demand for food in India, as it tends to have lower yields
than conventional agriculture, especially in the short term.
This can pose a challenge to Food Security and Poverty Alleviation, especially in
a country with a large and increasing population.
The recent Sri Lankan crisis was triggered by the policy of shifting to Organic
farming.
Rice, Sri Lanka's dietary staple, saw average yields slashed by some 30%.

High Capital Cost: Sustainable agriculture may require high initial investment
in infrastructure, equipment, and inputs, such as Irrigation systems, micro-
irrigation devices, organic fertilizers, and seeds.
This can be a barrier for small and marginal farmers who lack access to credit
and Subsidies.

Storage and Marketing Challenges: Sustainable agriculture may face storage

and marketing challenges in India, as it produces perishable and
heterogeneous products that require proper handling and packaging.
This can increase post-harvest losses and reduce the marketability of the
produce, especially in the absence of adequate certi cation and labeling
systems that ensure quality and traceability.

 Chapter 12: Recent Government Initiatives related to
sustainable Agriculture

In the budget speech, the Finance Minister of India rea rmed the
Government’s commitment to natural, chemical-free, organic and
Zero-Budget Natural Farming (ZBNF). It is the third time in the last four
budget speeches where (zero budget) natural farming nds a mention.

▪ In India, Natural farming is promoted as Bhartiya Prakritik Krishi

Paddhati Programme (BPKP) under Paramparagat Krishi Vikas
Yojana (PKVY).
◦ BPKP is aimed at promoting traditional indigenous practices
which reduce externally purchased inputs.
▪ Sub-mission on AgroForestry (SMAF) aims to encourage farmers
to plant multi-purpose trees together with the agriculture crops
for climate resilience and an additional source of income to the
farmers, as well as enhanced feedstock to inter alia wood-based
and herbal industry.
▪ National Mission on Sustainable Agriculture (NMSA) was
launched to develop, demonstrate and disseminate the
techniques to make agriculture resilient to adverse impacts of
climate change.
▪ Mission Organic Value Chain Development for North Eastern
Region (MOVCDNER) is a sub-mission under NMSA which aims
to develop certi ed organic production in a value chain mode.
▪ In the Budget 2022-23, Rashtriya Krishi Vikas Yojana has
received a 4.2-times (year-on-year) larger allocation of Rs 10,433
crore, which will earmark funds for the on-ground implementation
of chemical-free farming.
fi
fi
ffi
 Associated issues faced by the Government

Sikkim (India's rst organic state), has seen some decline in yields
following conversion to organic farming.
Many farmers have reverted to conventional farming after seeing
their ZBNF returns drop after a few years.
While ZBNF has de nitely helped preserve soil fertility, its role in
boosting productivity and farmers’ income isn’t conclusive yet.
An often-cited barrier by farmers in transitioning to chemical-free
agriculture is the lack of readily available natural inputs. Not every
farmer has the time, patience, or labour to develop their own inputs.
A study in Nature Sustainability states that while the nutrient value
of the natural inputs is similar to the chemical ones used in low-
input farms (farms using lower quantities of fertilisers and
pesticides), it is less in high-input farms.
• When such nutrient de ciencies are aggregated at a large scale, it
might hamper the yield over the years, potentially leading to food
security concerns.
Although the Budget 2022-23 envisages the promotion of natural or
chemical-free farming across the country, no speci c allocations
have been made to the Ministry of Agriculture and Farmers Welfare.
The currently-operational schemes such as the PKVY and the
National Project on Organic Farming also did not nd any mention
in the budget.

 What Measures Can Be Taken to Scale up Chemical-Free/
Natural Farming?

Going Beyond Ganga Basin: Focussing on promoting natural farming in rainfed

areas beyond the Gangetic basin.
Rainfed regions use only a third of the fertilisers per hectare compared to the
areas where irrigation is prevalent.
The shift to chemical-free farming will be easier in these regions.
Also, the farmers stand to gain as the current crop yields in these areas are low.

Risk Prevention for Smooth Transition: Enabling automatic enrollment of

farmers transitioning to chemical-free farming into the government’s crop
insurance scheme, PM Fasal Bima Yojana (PMFBY).
Any transition in agriculture — crop diversi cation, change in farming practices —
adds to the farmer’s risk.
Covering such risks could enhance the appetite of the farmers to embark on the
transition.

Providing Support to Agri MSMEs: Microenterprises that produce inputs for

chemical-free agriculture shall be provided support from the government.
To address the challenge of unavailability of readily available natural inputs, the
promotion of natural farming needs to be combined with the setting up of village-
level input preparation and sales shops.
Two shops per village across the country could provide a livelihood to at least ve
million youth and women.

Peer Farmers as Inspiration: NGOs and champion farmers who have been
promoting and practising sustainable agriculture across the country can be
leveraged for this purpose.
A CEEW (Council on Energy, Environment and Water) research estimates that at
least ve million farmers are already practising some form of sustainable agriculture
and hundreds of NGOs are involved in promoting them.
Learning from peers, especially champion farmers, through on- eld
demonstrations has proved highly e ective in scaling up chemical-free agriculture
in Andhra Pradesh.

Leveraging Community Institutions: Community institutions can be leveraged

for awareness generation, inspiration, and social support.
The government should facilitate an ecosystem in which farmers learn from and
support each other while making the transition.
Beyond evolving the curriculum in agricultural universities, there is a need to upskill
the agriculture extension workers on sustainable agriculture practices.

 Way Forward

▪ Providing nancial incentives for farmers to adopt

sustainable practices, such as direct payments,
subsidies for organic inputs, and crop insurance.
▪ Investing in research and development of sustainable
agricultural technologies and practices.
▪ Strengthening agricultural extension services to
provide farmers with training and information on
sustainable agriculture.
▪ Improving market access for sustainably produced
food through better infrastructure, marketing support,
and consumer awareness campaigns.
▪ Addressing land fragmentation through land
consolidation programs and promoting joint farming
initiatives.
▪ Strengthening environmental regulations and their
enforcement.
▪ Empowering women in agriculture through land
ownership rights, access to credit and resources, and
participation in decision-making processes.

 Chapter 13: Conclusion

According to the United Nations, by 2050, the global population is expected to add
another two bn people to today's gure of almost eight bn. Earth’s population is rapidly
expanding, and the need for more resources comes with that expansion - food production
is expected to increase by 70% to meet the demands of the booming population.
Today, more than one billion people depend on farming for income. The earth’s population
has become a growing concern regarding the possibility of producing that much food with
limited natural resources. Sustainable agriculture provides a solution for this increasing
concern.
This approach helps protect the environment and natural resources while promoting
economic pro tability and social equity, ensuring that all people have access to adequate
and a ordable food.

Bene ts of sustainable agriculture

Environmental Bene ts

Sustainable agriculture is an eco-friendly approach that reduces the reliance on limited

natural resources. Its careful farming methods, such as crop rotation, intercropping, and
companion planting, help protect soil health and water quality while eliminating the need
for damaging practices.
Economic Bene ts

Sustainability in agriculture can create stronger local economies and economic

opportunities for small-scale farmers, allowing them to produce more food with fewer
resources. It also has a signi cant nancial advantage over conventional farming. Droughts
or other natural disasters, such as oods, can a ect the yield from traditional farming,
leading to economic losses. Sustainable agriculture typically involves fewer expenses since
it encompasses far fewer inputs.
Social Bene ts

Sustainable agriculture encourages social equity and helps create a more equitable food
system. Through sustainable production methods, agricultural harvests can become more
reliable and adaptable over time, allowing consistent access to a ordable food for
everyone, regardless of their economic situation.
Furthermore, sustainable agriculture often promotes local farming due to the increased
ability of farmers to operate within a community.

Positive impacts on food security
Sustainable agriculture practices can have many positive impacts on food security. They
create a more e cient, stable, and resilient food system than traditional farming
practices, making it an e ective strategy for meeting the global demand for food.
Moreover, this approach provides a way to protect natural resources and mitigate climate
change e ects on crop yields, improving the ability to provide food for both the present
and future generations.
