NATURE BASED SOLUTION TO RESTORE AN URBAN WETLAND IN NEPAL
Through our collaborative program, Wetlands for Nepal our team member Manoj Mali presented about our work in biopesticide production. In this paper, we undertake a comprehensive journey, tracing our footsteps from the inception of the ‘Wetlands for Nepal’ initiative to the development of ‘Jholmal’ a biopesticide. We are now at the testing phase to assess the viability and effectiveness of ‘Jholmal’ as an eco-friendly pesticide. Jholmal is a homemade bio-fertilizer and bio-pesticide designed to enhance crop health and yield while simultaneously reducing production costs and the reliance on harmful chemicals. It is created by fermenting locally available resources like water, animal (cow/buffalo) urine, beneficial microbes-Jeevatu, and plant components in specific proportions. The use of animal urine serves a dual purpose, functioning as both a fertilizer and a pesticide, enriched with crucial nutrients like nitrogen, potassium, and phosphates. Furthermore, it possesses a wealth of advantageous characteristics, including antibacterial, antioxidant, anthelminthic, antibiotic, and antifungal properties.
IMPLEMENTATION OF NATURE-BASED SOLUTION: UNVEILING INSIGHTS FROM NAGDAHA, AN URBAN LAKE IN THE KATHMANDU VALLEY, NEPAL
Through our collaborative program, Wetlands for Nepal our team member Pratik Shrestha presented about our work in construction of sediment retention pond. The main threat to Nagdaha, an urban wetland was found to be sediment run-off coming from the southwestern quadrant of the catchment area. A pond was meticulously planned for construction as an exemplification of NBS, with a primary objective of optimizing the retention of sediments. We began by communicating with local authorities to convey the merits and benefits of our proposed solution, followed by dedicated work to secure the appropriate land for establishing the retention pond. Securing the designated land area proved challenging as landowners initially hesitated, however, our persistent efforts ultimately led us to successfully secure a suitable area for constructing the retention pond.
