Hemp Sustainability: Harnessing Hemp for a Sustainable Tomorrow

Hemp, often mistaken for its psychoactive cousin marijuana, is a versatile and robust crop with a rich history of use in various industries. Its resurgence in recent years is largely due to its numerous environmental benefits and potential to contribute to sustainable practices.

In this detailed article, we will explore the concept of sustainability, the unique properties of hemp, and how it stands as a hope for a greener future.

Understanding Sustainable Practices

Sustainability is defined as the ability to maintain a balance of a certain process or state in any system. In modern contexts, it often refers to the sustainable management of biological and human systems. Sustainable practices aim to meet the needs of the present without compromising the ability of future generations to meet their own needs.

The Three Pillars of Sustainability

Sustainability is typically understood through three interconnected pillars: social, economic, and environmental implications.

1. Social Implications

Sustainable practices must ensure the protection of global human rights. This includes addressing issues such as inequality, poverty, social injustice, and fair wages. True sustainability in agriculture and industry should leave a positive social impact, promoting equity and social well-being.

2. Economic Implications

The economic dimension of sustainability involves practices that support long-term economic health without causing harm to the environment or society. Sustainable agriculture, while not always immediately profitable, offers long-term benefits such as soil health and reduced dependency on non-renewable resources.

3. Environmental Implications

Environmental sustainability focuses on the responsible use of natural resources to prevent depletion and maintain ecological balance. This involves practices like renewable energy adoption, conservation efforts, and sustainable agriculture, all of which reduce environmental impact and preserve biodiversity.

Hemp is an extraordinary plant that requires significantly less water than cotton. Every part of the plant is useful, and it absorbs more carbon dioxide per hectare than most other crops and trees.

Cultivated for thousands of years, hemp is an eco-friendly plant with diverse uses in food products, biofuels, textiles, and even building materials.

Market Growth Potential

As awareness of hemp’s benefits increases, the global market could reach $18.6 billion by 2027, nearly four times the amount in 2020, according to a new UNCTAD report.

“The growing hemp market offers significant economic opportunities that all countries can capitalize on,” says Marco Fugazza, a UNCTAD economist and one of the report’s authors. “As a renewable product, the opportunities are sustainable. This is extremely important as countries try to boost their economies while protecting the environment.”

Untapped Trade Potential

The report, “Commodities at a Glance: Special Issue on Industrial Hemp,” highlights the untapped trade potential of hemp. About 40 countries produced approximately 275,000 tonnes of raw or semi-processed industrial hemp in 2019. However, just four countries—China, France, Canada, and the United States—account for more than half of the global output.

Clarifying Legal Status

Currently, most hemp products are bought locally. Global exports and imports amount to only $42 million, presenting a significant growth opportunity. This low trade figure is partly due to official statistics covering only a narrow set of hemp products and the stigma associated with hemp as part of the same family as cannabis. Although industrial hemp lacks intoxicating properties, the absence of a clear legal distinction makes it controversial in many countries.

The production of hemp was effectively banned in the United States in 1937 under the Marihuana Tax Act and only became legal again in 2018. To minimize risks and maximize opportunities, the report suggests that governments must clarify hemp’s legal status as a non-intoxicant.

Economic Opportunities for Developing Countries

The growing market for industrial hemp opens up significant economic opportunities for developing countries. Hemp’s versatility and functional characteristics make it valuable in agriculture, textiles, recycling, automotive, furniture, food and beverages, paper, construction materials, and personal care.

Hemp can grow in diverse climates, on land unsuitable for other crops, and helps replenish soil by removing heavy metals and other contaminants. Including hemp in crop rotation can lead to a 10% to 20% increase in wheat yields.

Reducing Waste and Pollution

Since all parts of the hemp plant—roots, flowers, fruit, stems, and leaves—are usable, growing hemp results in less waste and pollution compared to other crops. For example, in Africa, over 80% of the cotton plant’s mass is burned or discarded, contributing to heavy pollution. In India, smoke from burning cotton fields adds significantly to Delhi’s pollution each autumn.

By utilizing all parts of the hemp plant, developing countries can create sustainable production chains that promote rural growth and economic diversification. “Hemp cultivation may help to maximize the use of land and may also contribute to increasing incomes of farmers and rural communities,” the report states.
