Reviving Nepal’s Edible Treasures: Leaves, Roots and Traditional Delights

  - Nepal features outstanding Agro-biodiversity, thanks to its diverse climate and geography, ranging from the highlands of the Himalayas to the lush Terai plains. While modern agriculture has mostly concentrated on basic crops that involve rice, wheat, and maize, many traditional crops have progressively become obsolete. These neglected/minor crops, which range from tubers/corms and leafy greens to fruits and vegetables, have been farmed for millennia, bringing nourishment, resistance to severe conditions, and distinct tastes to the Nepali cooking.

Despite their value, these crops are frequently disregarded in conventional agriculture and markets. Nonetheless, many cultures continue to include them into their diets, cultural rituals, and traditional medicine. They are abundant in antioxidants, vitamins, and minerals, making them not only healthful but also sustainable, requiring less inputs and spontaneously adjusting to local circumstances.

In this blog, we will have a look at some of these overlooked treasures from a scientific, nutritional, and cultural perspective, as well as how they have historically been utilized in Nepali families. Understanding and supporting these crops can help to revitalize their production, maintain Nepal's agricultural legacy, and supplement our dietary habits with natural, healthful foods. 

Here is the list of some neglected/minor crops which carry great market potential yet underutilized:

1. Ivy Gourd ( Kundru / Kakari / Kundruni):

• Pickles (Achaar): In some regions, ivy gourd is pickled to preserve it for winter.

Historical Perspective:

Historically, Ivy Gourd was a staple in home gardens because it grows quickly and requires minimal care. Families would grow it alongside other vegetables, and it was often one of the first vegetables to be harvested in the growing season. Its versatility in cooking and traditional medicinal uses made it an indispensable part of daily life in Nepali households, particularly in rural areas where access to markets was limited.

Conclusion

The neglected/minor crops of Nepal such as Karkalo-Gaba, Pidalu, Tarul, Sakharkhanda, Gittha, Kerako Bungo, Kundru, Bethey saag, Latte saag, etc are hidden gems of nutrition, culture, and tradition. Although these crops grow abundantly around our homes, gardens, and local fields, they are rarely utilized to their full potential in commercial agriculture or markets.

Through this blog, we have highlighted not only their scientific and nutritional value but also their cultural significance and traditional uses in Nepali households. These crops have the ability to enrich diets, provide sustainable income for smallholder farmers, and preserve Nepal’s agricultural heritage.

It is time to recognize the market potential of these neglected/minor crops. By bringing them to the forefront, promoting their cultivation, and creating avenues for commercial marketing, Nepal can benefit from both improved nutrition and economic opportunities. Encouraging farmers, entrepreneurs, and consumers to embrace these indigenous crops can help transform them from overlooked plants into valuable assets for the Nepali marketplace.

Let us celebrate these crops, cultivate them wisely, and ensure that their full potential reaches every kitchen and market in Nepal.
