Hemp (Cannabis sativa L.Hemp is a plant with a millennia-old history that has been used for centuries to produce food, textiles, and building materials. In the 20th century, its cultivation was restricted due to associations with marijuana, but in 2025, hemp is experiencing a renaissance, particularly in organic farming. Thanks to its low water requirements, ability to sequester carbon dioxide, and improved soil health, hemp is seen as a key to sustainable development. Faced with global climate challenges and the need for crop diversification, hemp offers solutions that could revolutionize agriculture. This article examines the ecological and economic benefits of hemp, its applications, current trends in 2025, and the challenges facing farmers.

The ecological benefits of hemp

Hemp is one of the most sustainable crops in organic farming, offering numerous environmental benefits:

Carbon dioxide sequestration: Hemp is a carbon negative plant, absorbing up to 10 tons of CO₂ per acre through photosynthesis, making it an effective tool in the fight against climate change (ScienceDaily).
Water efficiency: Compared to cotton, hemp uses half as much water, which is crucial in drought-affected regions (UNCTAD).
Phytoremediation: The deep root system of hemp removes heavy metals and pollutants from the soil, supporting the regeneration of degraded areas (ScienceDirect).
Minimal use of pesticides: Hemp is naturally resistant to pests and weeds, which eliminates the need for chemical pesticides, perfectly fitting the principles of organic farming (PMC).
Improving soil health: Hemp enriches the soil with organic matter and increases the yields of subsequent crops in the rotation by 5-15% (X post).

These characteristics make hemp an ideal choice for organic farming, which emphasizes natural processes and minimizing environmental impact.

Economic benefits

Hemp offers significant economic benefits to organic farmers, especially in 2025, as demand for hemp products increases. According to the report Fortune Business Insights, the global industrial hemp market, valued at $9.47 billion in 2024, is expected to grow to $47.82 billion by 2032 at a CAGR of 22.7%. In organic farming, hemp offers higher margins than traditional crops like corn and soybeans, which struggle with oversupply and low prices (Heartland).

Hemp can be grown for seeds (food, oil) and fibers (textiles, bioplastics), providing farmers with a dual source of income. For example, organic hemp seeds command prices two to three times higher than conventional grains, making them an attractive alternative. A Vermont study found that a small hemp sector could boost the local economy by $0.81 million and create 13 jobs, while a larger sector could generate $30 million and 439 jobs (ResearchGate).

Hemp Applications in Sustainable Development

Hemp is versatile and its uses support the UN Sustainable Development Goals such as Zero Hunger (SDG 2), Good Health and Well-being (SDG 3) and Climate Action (SDG 13):

Food: Hemp seeds contain 30% protein and an ideal ratio of omega-6 to omega-3 fatty acids (3:1), supporting heart health and preventing disease (PMC).
Textiles: Hemp fibers are more durable than cotton, block 95% UV rays and have antibacterial properties (ScienceDirect).
Building materials: Hempcrete offers excellent thermal insulation and mold resistance, with a thermal conductivity of 0.06–0.19 W m⁻¹ K⁻¹ (ScienceDirect).
Bioplastics: Hemp can replace traditional plastics by offering biodegradable alternatives (X post).
Bioenergy: Hemp biomass can be used to produce biofuels, although some processes may increase CO₂ emissions (ScienceDirect).

These uses make hemp a key part of the circular economy, where all parts of the plant are used, minimizing waste.

Case studies

Vermont, USA: A 2005 study found that Vermont's hemp sector could significantly support the local economy, generating millions of dollars and hundreds of jobs through fiber cultivation and processing (ResearchGate).
Italy: A 2024 study in Tuscany analyzed the environmental impact of hemp cultivation, showing that organic methods reduce the carbon footprint and improve soil quality (Frontiers).
Pennsylvania, USA: The Rodale Institute has shown that hemp grown in a no-till system with cover crops such as vetch provides comparable yields without the need for synthetic fertilizers (Rodale Institute).

Challenges and the future

Despite its potential, hemp faces barriers:

Legal regulations: In Poland, hemp cultivation requires permits, and unclear regulations may discourage farmers (European Commission).
Infrastructure: The lack of processing plants limits the possibilities of selling hemp products (Heartland).
Market: While demand is growing, prices for hemp products can be volatile, requiring expanded supply chains.

In 2025, research on the hemp microbiome opens up new possibilities for increasing yields and fiber quality (ScienceDaily). EU support, such as funding for organic farming, can accelerate the development of the sector (European Commission).

Hemp in organic farming is key to achieving sustainability in 2025. Its ability to sequester carbon, improve soil health, and minimize pesticide use makes it an ideal choice for organic farming. Economic benefits, such as high margins and the growing popularity of hemp products, further strengthen its position. As regulations become clearer and research drives innovation, hemp has the potential to revolutionize agriculture, supporting a healthier planet and economy.
