Hemp

Call to action:

Support the development of hemp plants and products to restore soils, sequester carbon, provide food and fiber, and sustain local economies.

For millennia, hemp (cannabis sativa) has been cultivated as a source of food and fiber to make rope, paper, textiles, shoes, and lamp oil. Hemp plants grow quickly and thrive in many regions. Hemp seeds are a good source of plant-based protein, vitamin B1 (thiamine), and minerals like manganese, copper, magnesium, and phosphorus. Hemp plants enhance soil health and sequester carbon dioxide twice as effectively as trees. Hemp can prevent deforestation by replacing wood to make paper as well as certain types of building materials. It is a biodegradable alternative to plastic. It uses water six times more efficiently than cotton plants. In the early 20th century, hemp was banned by the U.S. government along with its cousin marijuana. In 2018, hemp was decriminalized and is now enjoying a resurgence, though it faces ongoing challenges, including stigmatization, stringent regulation, and competition from cannabis growers. Despite these obstacles, hemp’s versatility makes it a botanical ally in addressing climate change, especially if its market potential can be expanded and hemp products become critical in regenerative agriculture.

Learn about the history of industrial hemp and its many benefits. Hemp is a common, fast-growing, sun-loving plant cultivated by civilizations throughout history as a source of food, oil, fiber, and medicine. Originating on the Tibetan Plateau, hemp spread along the Silk Road trade route. Known as a “camp-follower,” the plant quickly colonizes disturbed land and compost heaps. Over the centuries, humans have cultivated various hemp strains for different purposes, including its recreational effect. In 1839, an Irish doctor presented the first known clinical trials of the plant as medicine. By the turn of the century, hemp was a commonly used pharmaceutical in the U.S. and Europe. Industrial hemp is legally defined as cannabis containing 0.3 percent or less of the psychoactive compound THC. There are multiple reasons why hemp is considered a regenerative crop, including:

Carbon sequestration and soil health. Hemp grows fast and tall, typically reaching maturity within 100 days. Due to its rapid photosynthesis cycle and deep roots, it is highly efficient at drawing carbon dioxide from the atmosphere and converting it into plant biomass. The carbon gets stored in the plant and soil. When hemp fibers get made into products such as textiles and building materials, they contribute to long-term carbon sequestration. The root systems of hemp plants improve soil structure and promote nutrient cycling and water retention.
Pesticides. Hemp is naturally pest-resistant, which means it can be cultivated with few or no pesticides.
Biodiversity. Hemp produces large amounts of pollen in late summer, which attracts pollinating insects. It provides shelter for birds, and hemp seeds are a food source for animals.
Prevents soil erosion. The dense leaves of hemp plants are a natural soil cover, protecting it against erosion. Fast-growing hemp can cover the ground just three weeks after germination.
Protecting forests. As a renewable and fast-growing source of fiber, hemp can be used as an alternative to wood-based products, preserving vital forest ecosystems.
Water efficiency. Hemp is known for being relatively drought-tolerant, with certain species exhibiting very efficient water use. This characteristic makes it a valuable resource in regions facing water scarcity or where sustainable water management is concerned.
Carbon-neutral and low-impact products. Hemp-derived products, such as hempcrete (a building material made from hemp fibers), have the potential to be carbon-neutral or even carbon-negative. This means that the overall carbon emissions associated with these products’ life cycle could be offset by the carbon sequestration and sustainability practices associated with hemp cultivation (see Carbon Architecture Nexus).
Decomposition. Products made from hemp are biodegradable and compostable, decaying quickly and returning nutrients to the soil. It is easily compostable (see Compost Nexus).

Learn about the obstacles to the utilization of hemp. At the turn of the 20th century, the expanding use of marijuana as an intoxicant caused a shift in public attitudes, spurred by politicians and others who stigmatized cannabis with a racist misinformation campaign that associated it with ethnic minorities and immigrants. As a result, cannabis and hemp were banned wholesale in 1937, which reduced hemp production globally for decades. After a long campaign by advocates and growers, the 2018 Farm Bill removed hemp from the Controlled Substances list in the United States. Commercial production of hemp started the following year. Although there has been significant progress, including the USDA’s Partnerships for Climate-Smart Commodities program, which recently awarded $35 million to several hemp-specific projects, there continue to be significant challenges to the industry's growth.

Prejudices against cannabis persist, and a stigma continues to be attached to hemp in many parts of the world.
Financing hemp production through conventional banks can be difficult since cannabis remains illegal at the federal level in the U.S. Only one in ten banks will provide services to hemp growers.
As marijuana is decriminalized at the state level – currently, thirty-eight states have done so for medical use, and twenty-four states for recreational use – farmers, distributors, and retailers have flocked to marijuana production, leaving hemp producers at a disadvantage.
Challenges to hemp growers include a lack of production and market data, the labor-intensive nature of the crop, and the stringent regulations on THC levels.
The hemp industry is young, creating more profit variability than mature markets for other crops and products.

Choose hemp products. Whenever possible, purchase products that use hemp as a raw material, such as clothing, food, household items, and others. This creates demand and supports companies in the hemp industry. In particular, support hemp businesses that prioritize sustainable and environmentally friendly practices and encourage businesses to adopt sustainable packaging for their hemp products.
