Chemical Pesticides and Environment Sustainability

Need for alternative pest control methods, organic farming

Raheeba Tun Nisa

Naveed Hamid

Chemical pesticides are frequently used to protect plants, animals, livestock, and crops from pests and diseases. In India, estimated annual production losses due to pests are as high as US$ 36 billion. The use of pesticides has significantly increased and improved global food production.

Pesticides are used by farmers, consumers, and businesses to stop the spread of disease and crop destruction. In order to safeguard the world’s food supply, pesticides assist the agricultural community in managing exotic weeds, diseases, and insects.

All types of pesticides used in the country, including those imported from other nations, are governed by the Environmental Protection Agency (EPA) of the United States. When seeking to market their products, pesticide manufacturers must comply with extremely strict regulations set forth by the EPA. The amount of pesticide residue reported on food products ingested by humans or animals, such as livestock feed, is regulated by the EPA.

However, there is still a flaw in the system that causes environmental chaos, and we are unable to stop the devastation of our ecosystem.

Impact of pesticides on environment and SDG goals

Pesticides however might have a negative effect on both aquatic and terrestrial species. Their extended and repeated use causes bioaccumulation. It is possible for pesticides to spread from the application site to distant surroundings and non-target creatures. Even at low concentrations, water contaminated with pesticides poses a major threat to the environment. Pesticide residues can reach humans through contaminated food and water, non-target drift, or application.

Exposure to pesticides can have a variety of negative neurological health impacts, including impaired coordination, memory, and vision. The immune system is also harmed by prolonged pesticide exposure. An increase in neurological conditions, including brain tumours, has been attributed to excessive pesticide use in Kashmir.

Different soil microorganisms are necessary for various plant functions yet using pesticides may limit the soil microflora. We know a lot of beneficial microorganisms are present on the plant surface (Phyllosphere) as well as in the root zone (rhizosphere), indiscriminate use of pesticide drastically decrease their population.

Numerous herbicides have been shown to be harmful to mycorrhizal fungi, increase plant susceptibility to diseases, impair seed quality, and have indirect effects on bird populations. SDG target by 2020 is to minimize the negative effects on human health and the environment by achieving the environmentally sound management of chemicals and their wastes throughout their life cycles, in compliance with accepted international frameworks, and greatly reducing their release to air, water, and soil.

Pesticides must be used in accordance with the standards established by national and international law, with better safety precautions and less harmful formulations. Farmers should be made aware of the need to avoid using harmful pesticides.

Strategies to minimize the usage of chemicals

In the future, it will be possible to combine the use of chemical pesticides with natural remedies to eradicate pests and insects in a more long-lasting manner. The best alternatives to pesticides are agronomical approaches, biological control, organic farming, integrated pest management, and the use of resistant varieties.

Current disease management approaches rely primarily on synthetic pesticides, but growing awareness of these chemicals’ detrimental effects on the environment and human health has prompted us to seek out more effective, less or non-toxic alternatives.

One such alternative is biological control of plant diseases that could be a viable alternative to expensive chemical fungitoxicants, which not only harm the environment but also allow for the development of resistant pathogenic strains. The biocontrol agents either soil-derived or epiphytes or endophytes (bioagents acquired from phyllosphere) are having the innate potential of suppressing the diseases.

It may be effective to use endophytes and epiphytes that are strongly antagonistic to this pathogen to tackle the disease. In the future, biological control on aerial plant surfaces will be successful not only because of its efficiency but also because of its low cost compared to traditional pesticides and the absence of harmful side effects from the organisms used, such as mammalian toxicity.

Other advantages of biological control over chemical control might include the less long-term environmental impact from the use of persistent pesticides and the lack of chemical residues on edible components of the crop. Several commercial microorganism-based products have been created and are beginning to gain popularity in the market. However, due to biocontrol action’s diversity and inconsistency, large-scale usage is still limited. In some circumstances, this might be due to the biocontrol agents’ susceptibility to environmental impacts.

There are several ways to overcome biocontrol limitations and increase its performance. One such way is a combination of biocontrol agents with fungicides. Compatibility of any bioagent with fungicides is a key to developing an efficient disease management module vis-à-vis disease control, resistance management, environmental safety and economy.

Need to boost and promote natural farming startups

From 2010-2011, the organic market in India witnessed considerable growth. According to a TechSci Research report, ‘India Organic Food Market By Product Type, Competition Forecast and Opportunities, 2011 – 2021’, India’s organic food market is estimated to grow at a CAGR of over 25% during 2016-2021. With the rising environmental and health problems, more and more people are becoming cautious of the harmful effects of pesticides, synthetic fertilizers and other artificial chemicals used for food production. There is growing consensus among people about the benefits of using Organic products. This unique rise in demand has resulted in creating an opportunity for many to come up with great and novel ideas in the shape of startups with unique business models, aimed at solving this modern-day crisis.

Can kiwi cultivation prove alternative to apple production in Kashmir?

Can kiwi cultivation prove alternative to apple production in Kashmir?

Dhaar Mehak M

Misbah Bashir

The horticulture sector is seen as the backbone of the Kashmir economy steadily replacing the tourism sector in terms of sustainability and future prospectus. Given the environmental feasibility, Kashmir has been identified as one of India’s most dynamic horticulture hotspots. During the final decades of the 20th century, the region of Kashmir has seen a steady shift from paddy cultivation to apple cultivation. For quite some time the output and outcomes from the orchards of Kashmir have been high. This has ushered in a wave of optimism and people have been heavily investing in high-yielding apple varieties. More or less on an annual basis, people have revealed satisfaction with the outcomes.

Can kiwi cultivation prove alternative to apple production in Kashmir?

The year 2022 has been identified as a bumper year of apple production in Kashmir (apart from other horticulture products). The apple blooms in spring were studied and identified by the experts where it was predicted that the year from across the valley was going to deliver a bumper crop. A wave of happiness ad optimism ran in the supply chain from orchardists to the dealers. Given the demand and pricing trends of previous years, the expected outcomes from 2022 were anticipated to surpass the mean value of the previous decades by a double-digit. However, as the output was ready and entered the market, the returning price was the lowest registered in the previous decade. Among many other factors, a predominant factor behind this was the bulk Indian import of Iranian and Turkish Apples that captured the market and wiped out the demand for Kashmiri apples.

Looking through an alternative economic and horticultural lens, the complete reliance on apples as the sole and dominant outcome of the horticulture sector in Kashmir is a risk of putting all the eggs in one basket. The first step to diversification has been identified as a steady production of kiwi fruit. In contemporary times the only state that is producing kiwis in India is Himachal Pradesh. Lately, Himachal orchardists have realized that diversification is important, and the immediate consequence has been a steady shift to kiwi production. The environmental conditions in both Himachal and Kashmir are equally preferable for kiwi production.

Can kiwi cultivation prove alternative to apple production in Kashmir?The plantation season for kiwi trees is February and March, while the irrigation season is May to July. The plantation takes much less land space than the apple trees. Vegetables and other seasonal crops can be grown in-between the kiwi tress. There are no pesticides of any kind needed for kiwi plantations while on the other hand the apples of all types highly rely on a number of pesticides, insecticides and herbicides. This quality makes kiwis organic in nature, better fitting the contemporary market demand. The overall maintenance of kiwi plantations is much easier and cheaper as compared to that of apples. At the same time, the demand and prices for kiwis in the local, national and international markets is much stable as compared to that of apples.

In the first week of November the average price of 18 kgs of Apples in Sopore Mandi peaked at Rs.350 which doesn’t even cover the half basic price of production. Quite contrary to this, one unit of kiwi costs Rs.35 in the local market and one kiwi plant yields 70 kg of kiwis on an average. One kg of dried Kiwis costs Rs.1800 in the market. And the demand for kiwis is very high both in the national and the international markets.

At the moment, SKUAST-K is actively researching in the direction of improvising the kiwi plantation suitable specifically to the Kashmir region. Simultaneously, sale of the kiwi trees is carried-out from time to time. Lately a small number of orchardists from the Baramulla and Sopore area of North Kashmir have been steadily diversifying towards kiwi production. However, during their experimental stages, they are more than happy with their outcomes. The market value of the output has been promising and so is the durability of the output. The kiwi packaging however is different from that of the apple packages and the kiwi farmers of Kashmir complain that at the moment they are not able to find the required packaging solutions.

Can kiwi cultivation prove alternative to apple production in Kashmir?Putting all these factors together, kiwi production can be the next big horticulture venture of Kashmir. Risk minimisation is the first and far most expected benefit from this diversification. If due to some market fluctuations, apples fail to fetch the required price in the market the kiwi market can come to cushion and minimize the damage and losses. The second expected spill-over of kiwi diversification can come in the form of growth in the local corrugated industry. In the present time, the Kashmir corrugation industry mostly specializes in the production of apple boxes. However, with the growth of kiwi production, the corrugation industry will get to diversify and increase its output and employment potential. The cold-store industry of Kashmir is also expected to grow with the growth of kiwi production as the local producers can control the market supplies from time to time in light of the expected profits. The kiwi processing units also have a very high potential of starting up in the region.

Somia Sadaf, a native of Kupwara’s Batargam area has started her own dairy business. Sadaf has 10 Holliston Friesan and Jersey cows, 25 Kanal of irrigation land, and 200 Keystone Golden birds with technical help from Krishi Vigyan Kendra Kupwara. She uses a lawn cutter to maintain her property of land and cows.

Somia has also given instruction in the scientific raising and management of cows. She keeps herself up to date about new technologies regarding the maintenance of her land and the marketing of milk. She receives technical assistance for livestock illness management in order to optimise the production of milk and poultry. KVK continually performs and monitors the vaccination and deworming of animals at her farms.

Integrated Farming System

KVK has provided all assistance necessary to set up vermicompost pits so that cow manure is turned into a more lucrative vermicompost. Red worms have also been supplied by KVK for the pits. For additional revenue creation, KVK has also assisted in establishing 200 Keystone Golden-based backyard poultry farm. She has recently started fish farming under the NRLM. Somia’s farming is the best example of an integrated farming system, which can serve as a model for the rest of the farm women.

She manages to sell 150 kg of milk every day worth Rs 6,000. She collects 150 eggs and sells 100 eggs daily. Her daily poultry revenue is Rs 1500 and her daily net income is Rs 7500.

Her marketing plan includes selling products at Kisan Melas hosted by SKUAST Kashmir or the line departments, as well as supplying milk to nearby hotels and neighbours and eggs to neighbourhood clients.

Over the course of her entrepreneurial venture, her family has consistently supported her.

“Support from the family is highly commendable when it comes to managing and feeding cows,” says Somia.

Her accomplishment is partly a result of Krishi Vigyan Kendra in Kupwara’s ongoing technical assistance and supervision.

She was honoured with the district, state, national level and National Rural Livelihood Mission-related certifications, medals, prizes, nominations, and recognition as a successful woman entrepreneur.

Additionally, she has trained 200 farm women in knitting.

Towards self-sufficiency in animal feed

Formulation of area-specific mineral mixture for livestock

Parvaiz Ahmed Reshi

In Kashmir Valley, paddy straw forms the predominant part of fodder available for livestock feeding along with a limited amount of oats and concentrates, causing, therefore, energy, protein, vitamin and mineral deficiencies. Though the deficiencies of energy and protein are rectified by various means, vitamin and mineral deficiencies become more intensified, causing poor production performances in animals and consequently losses to livestock farmers. Moreover, the mineral profile of soils and therefore feeds and fodders grown on such soils vary with topography and therefore is often a region-specific problem, demanding the study of the mineral profile of soils and fodders regionally and production of region-specific mineral mixtures for rectifying such mineral deficiencies in animals.  Further being a hilly region Kashmir valley is geographically different from the rest of the country and mineral mixtures produced elsewhere in the country may not hold good for the valley livestock. Various studies including work carried out by the proposer of this startup have found deficiencies of various macro (Ca, P) and micro (Zn and Cu) minerals in feeds and fodders in various districts of Kashmir valley that necessitate supplementation for optimum production and reproductive performances from animals.

Manufacturing and production of Area Specific Mineral Mixtures (ASMM) to help farmers and entrepreneurs get more production and reproduction performances from livestock and create a meaningful and enduring mineral mixture production technology for the benefit of livestock farmers in Kashmir Valley who by virtue of its topography is geographically different (Hilly temperate) from rest of the country (Tropical) was an uphill and an achievable target. An attempt was made in this direction and a specific mineral mixture based on the mineral profile of soil, composite fodder and blood of the livestock being reared in Ganderbal district was formulated

Outcome

The formulated mineral mixture was distributed among farmers belonging to Lar, benhama, Arch, Malpora and Nunner for feedback with respect to the milk and reproductive performance. Also the mineral mixture was kept available for sale among farmers at the university seed mela for the 4 consecutive years and farmers were questioned for the milk and reproductive performances.  A common questionnaire was developed for the purpose using simple language acceptable and easily filled by the team leader of the farmers and information with respect increase in milk production, health status, and reproductive efficiency was collected. Based on the feedback received, It was roughly concluded that there was increase in milk production, reproductive efficiency (conception rate) and income generation of the farmers. This can be verified from the fact that the formulated mineral mixture is in great demand and the farmers have been repeatedly asking and purchasing the product. the product is popular among farmers and adoption rate is increasing day by day.
