Agrobiodiversity conservation through local innovation and practices in Nepal – By Sulochana Bhandari || Krishi Vines

Introduction 

In Nepal, the term “agrobiodiversity” refers to the range and diversity of flora, fauna, and microbes that are either directly or indirectly utilized for agriculture, food production, and subsistence. With a geography that varies from the lowland Terai to the Himalayan mountains, Nepal provides a rich and distinctive biodiversity that is conducive to a variety of agricultural practices. In order to maintain traditional knowledge, encourage sustainable farming methods, and guarantee food security, diversity is essential.  Similarly, The preservation of the variety of plant and animal species utilized in agriculture, as well as the ecosystems and cultural traditions that support this diversity, is referred to as agrobiodiversity conservation. In order to maintain food security, the health of the ecosystem, and agricultural resistance to environmental changes like pests, diseases, and climate change, conservation activities seek to protect agricultural biodiversity.

Importance of Agrobiodiversity Conservation 

Nepal’s large natural diversity, traditional farming practices, and dependence on smallholder agriculture make agrobiodiversity conservation there especially important. Nepalese farmers have created solutions to maintain livelihoods, improve resilience, and support biodiversity through local ingenuity and practices. The following are the salient features of Nepalese agrobiodiversity conservation through innovative local practices:

1. Resilience to Climate Change and Environmental Stress

1. Climate Adaptation: Nepal’s farmers use traditional knowledge to adapt to diverse and changing climatic conditions across the country’s varied agro-ecological zones. By cultivating a wide range of climate-resilient crops such as millet, barley, and buckwheat in higher altitudes, and rice and maize in the lowlands, farmers ensure adaptability to changes in temperature, precipitation, and other environmental factors.
2. Cultural Innovation in Seed Selection: Local farmers innovate by selecting and preserving seed varieties that are well-suited to withstand extreme weather events, such as drought-resistant crops in the dry areas of western Nepal or flood-tolerant rice varieties in the low-lying Terai.

2. Food Security and Nutritional Diversity

1. Diverse Diets: Agrobiodiversity plays a crucial role in providing diverse and nutrient-rich diets in Nepal’s rural communities. By growing a wide variety of crops like vegetables, legumes, cereals, and fruits, smallholder farmers ensure year-round availability of food. This diverse cultivation supports food security, especially during lean seasons or crop failures.
2. Conservation of Traditional Crops: Local innovations, such as maintaining community seed banks and exchanging traditional crop varieties, contribute to conserving agrobiodiversity while promoting nutritious, native crops. This approach helps prevent the loss of traditional, underutilized crops that are essential for balanced nutrition.

3. Preservation of Traditional Knowledge and Cultural Heritage

1. Indigenous Agricultural Practices: Nepal’s diverse ethnic and indigenous communities maintain unique agricultural systems passed down through generations. These systems, such as terrace farming in the mid-hills or rotational grazing in the highlands, are specifically adapted to local environments and biodiversity. Preserving this knowledge is essential for continued biodiversity conservation.
2. Seed Saving and Exchange Systems: Local innovation through seed-saving practices ensures the conservation of a wide range of plant species. Farmers in Nepal often exchange seeds within communities, helping to conserve diverse crop varieties and ensure resilience to pests and diseases.

4. Innovation in Sustainable Farming Practices

1. Agroecological Practices: Nepal’s farmers have adopted agroecological innovations, such as integrating pest management, organic farming, and composting techniques, which conserve biodiversity while enhancing crop productivity. These sustainable methods reduce reliance on chemical inputs and promote ecological balance.
2. Intercropping and Polyculture: By practicing intercropping and polyculture (growing multiple crops together), Nepalese farmers encourage biodiversity on their farms. These practices improve soil health, reduce pest outbreaks, and increase crop yields without harming the environment.

Challenges of Agrobiodiversity conservation through local Innovation and practices

Effective conservation efforts in Nepal are hampered by a number of issues and constraints, despite the significance of preserving agrobiodiversity through innovative local methods. A confluence of institutional, environmental, and socioeconomic variables give rise to these problems. The following are some of Nepal’s primary issues with protecting agrobiodiversity:

1. Loss of Traditional Knowledge

1. Generational Shift: As younger generations migrate to urban areas for better opportunities, traditional agricultural knowledge is at risk of being lost. The decline in the transmission of indigenous farming practices, seed selection methods, and local biodiversity management threatens the conservation of agrobiodiversity.
2. Cultural Erosion: The rapid globalization and commercialization of agriculture often lead to the marginalization of traditional practices and crops. This cultural shift may diminish the value placed on local knowledge and biodiversity.

2. Monocropping and Modern Agricultural Practices

1. Adoption of High-Yield Varieties: The widespread adoption of high-yielding, uniform crop varieties promoted by agricultural policies and commercial seed companies often leads to monocropping practices. This reduces genetic diversity and undermines the cultivation of traditional varieties.
2. Chemical Dependency: The reliance on chemical fertilizers and pesticides associated with modern agriculture can harm soil health and biodiversity, disrupting local ecosystems and diminishing the resilience of traditional farming systems.

3. Climate Change Impacts

1. Increasing Vulnerability: Climate change poses a significant threat to agrobiodiversity in Nepal. Changes in temperature, precipitation patterns, and the frequency of extreme weather events can impact crop yields and the viability of traditional varieties, leading to a loss of biodiversity.
2. Inadequate Adaptation Strategies: Many local farmers lack access to information, resources, and technologies needed to adapt their practices to changing climatic conditions, resulting in reduced agricultural productivity and increased vulnerability.

4. Land Use Change and Habitat Destruction

1. Urbanization and Infrastructure Development: Rapid urbanization and infrastructure projects lead to the conversion of agricultural land into urban areas, reducing available habitats for traditional crops and livestock. This threatens the sustainability of local farming systems and contributes to biodiversity loss.
2. Deforestation and Land Degradation: Unsustainable agricultural practices, deforestation, and land degradation diminish natural habitats and the ecosystem services they provide, further impacting agrobiodiversity.
3. Weak Community Institutions: In some regions, local institutions responsible for managing agrobiodiversity may be weak or lack capacity. This limits their effectiveness in organizing conservation efforts and supporting local farmers.

Solution to the Problem in preserving the local innovation 

Nepal has to take an integrative strategy to address the issues of agrobiodiversity conservation through local innovation and practices. This strategy should include policy support, community participation, education, and sustainable agriculture practices. Here are a few crucial fixes for these issues:

1. Strengthening Local Knowledge and Practices

1. Documentation and Promotion: Document traditional farming practices and indigenous knowledge systems, and promote them through local agricultural extension services and community workshops. This can help revive interest in traditional methods and encourage younger generations to engage in agriculture.
2. Participatory Research: Facilitate participatory research initiatives where farmers work alongside researchers to develop and test sustainable agricultural practices. This collaborative approach ensures that local knowledge is integrated into scientific research.

2. Supporting Diverse Agricultural Systems

1. Agroecological Practices: Promote agroecological practices that enhance biodiversity, such as crop rotation, intercropping, and organic farming. Training programs can help farmers adopt these practices, leading to improved soil health and crop resilience.
2. Community Seed Banks: Establish and support community seed banks where farmers can store and exchange traditional seeds. This enhances access to diverse genetic resources and helps preserve local crop varieties.
