Indigenous Knowledge: A Cornerstone of Agro-Biodiversity Conservation in Nepal – By Bhawana Khadka || Krishi Vines

Nepal’s rich cultural and biological diversity is embodied in its Indigenous communities, which constitute about 35.08% of the population. Recognized officially in 2002, these communities encompass over 92 distinct ethnic groups and languages, each possessing unique cultural practices and knowledge systems. This indigenous wisdom is vital for understanding, conserving, and sustainably utilizing agro-biodiversity, a crucial aspect of Nepal’s agricultural landscape.

Understanding Agro-Biodiversity

Agrobiodiversity the subset of biodiversity within agricultural systems includes all the varieties and variability of animals and plants and micro-organisms that allow farms to function, as well as wild foods; it is what feeds us. Indigenous communities are deeply connected to their ecosystems, honed over generations through oral traditions, stories, and cultural practices. This knowledge encompasses various aspects of agro-biodiversity, including identifying plant and animal species, cultivation techniques, and the ecological relationships that sustain them. Such understanding is essential for conserving diverse species and their habitats.

Conserving Agro-Biodiversity

Indigenous practices play a critical role in promoting sustainable agriculture. Traditional techniques such as crop rotation, intercropping, and natural pest control contribute to soil fertility and ecological balance. Agrobiodiversity not only enhances agricultural productivity but also provides essential ecosystem services such as climate change mitigation and adaptation. However, this diversity is under threat due to modern agricultural practices, climate change, and urbanization.

Cultural Practices and Traditional Knowledge

The Tharu community exemplifies how traditional practices can promote sustainability. Their eco-friendly crafts, like woven baskets, and architectural designs showcase adaptations to local climates and environmental challenges. Practices such as using cattle urine as a pesticide or drying foods for preservation (e.g chhurpi,pickle ,gundruk )  highlight the innovative ways indigenous knowledge contributes to sustainability.

Moreover, honey hunting in mountainous regions showcases a vital traditional practice that supports ecological balance while providing nutrient-rich food sources. Such practices also foster smallholder agriculture, where diverse crops are planted for subsistence and income. They  have established sacred groves or community forests to protect biodiversity-rich areas, or they have developed traditional practices to conserve endangered species. This knowledge is essential for identifying and protecting species that are at risk of extinction due to climate change and other threats.

Furthermore, indigenous communities have developed traditional practices for reducing greenhouse gas emissions and mitigating climate change. For example, they have used agroforestry systems to sequester carbon, or they have developed sustainable land management practices that reduce soil erosion and conserve water resources.

Informing Climate Change Adaptation and Mitigation

Indigenous knowledge is invaluable in addressing climate change. Insights from traditional ecological practices can help identify resilient crops and livestock breeds. Communities have historically adapted to climate variability through innovative agricultural strategies, such as agroforestry systems that sequester carbon and reduce soil erosion.

Furthermore, Traditional wisdom is used by villagers to build routes for humans and animals in rural regions, as well as to preserve slope stability by calculating the width and height of steps. Communities also construct drywall and biological barriers to protect communities from flooding, landslides, erosion, side-cutting, and slope failure. Communities’ capacity to tolerate new stressors and adapt to the disaster impacts that climate change may increase can be enhanced by this knowledge base and practices.

Challenges and Opportunities

Despite its significance, indigenous knowledge faces numerous challenges, including globalization and the erosion of traditional cultures. Urbanization and modernization often marginalize these communities, reducing their role in decision-making about natural resource management.

However, there are opportunities to leverage indigenous knowledge in agro-biodiversity conservation. By documenting and recognizing traditional practices, governments and NGOs can help preserve this vital resource. Integrating indigenous wisdom into climate change strategies can also enhance the effectiveness of adaptation and mitigation efforts.

Conclusion

Indigenous knowledge is a critical asset for conserving agro-biodiversity in Nepal. By embracing traditional practices and fostering collaboration among indigenous and local communities, we can enhance resilience against climate change and safeguard the rich agricultural heritage of Nepal. Supporting the transmission of this knowledge not only benefits biodiversity but also strengthens cultural identities and sustainable futures.
