“…The environmental effects of applying pesticides to crop fields can be widespread because these substances can be absorbed, spread by wind, and water. A lot of widely used pesticides damage non-target organisms as well as the environment and cause pollution in addition to their intended targets (Nyaupane, 2022). Human health concerns from exposure to these pesticides include immunological suppression, neurological disorders, anomalies of the reproductive system, hormonal imbalances, and possibly cancer (Kaur et al, 2024).…”

Agriculture serves as the mainstay of Nepal's economy, sustaining livelihoods for a significant portion of the population and contributing substantially to Gross Domestic Product (GDP). This study conducted in Panchkhal Municipality of Kavrepalanchok district, employed a qualitative approach of research to explore lived experience of farmers regarding the impacts of climate change on their livelihoods. Through the use of both primary and secondary data, the research finds that climate change has caused a number of problems for the farmers in Panchkhal, such as reduced water availability due to drying up of small streams and disappearance of springs affecting the rain-fed farming. Additionally, farmers grapple with rising incidences of pests and diseases in crops, health problems associated with pesticide use, lower productivity, flooding, and a move away from farming. The two biggest effects that stood out among them were the scarcity of water and the increase in diseases and pests in crops. The study also underscores farmers' heightened awareness of climate change impacts and extreme weather events with a particular emphasis on the perceptible decrease in rainfall frequency and volume, along with delayed monsoon onset.

“…The indiscriminate application of chemical pesticides poses significant risks to the environment and human health (Jallow et al, 2017). Nyaupane (2021) explores the use of insecticides in Nepal, addressing their environmental impact, resistance issues, and global regulations in the chapter titled "Use of Insecticides in Nepal, Its Impact and Alternatives of Insecticides for Nepalese Farmers". Plant protection, a vital aspect of agriculture, involves strategies and approaches for pest management throughout the crop life cycle, encompassing pre-and postharvest stages (Adhikari, 2017).…”

This comprehensive review delves into the evolving landscape of Nepalese agriculture, where 60.4% of the population is engaged in farming. As globalization reshapes the sector, Nepalese agriculture grapples with the transition from subsistence to market-oriented practices, marked by the widespread use of high-yielding varieties and chemical inputs. This shift, while addressing immediate food demands, has led to severe consequences, including soil degradation, loss of biodiversity, and threats to environmental sustainability. In response, traditional plant protection practices emerge as a beacon of hope, offering eco-friendly and sustainable alternatives. The review explores a plethora of indigenous strategies deployed by Nepalese farmers, ranging from handpicking pests to innovative approaches like the use of wooden ash, urine, dung, and bio-pesticides such as Jholmal. These methods not only provide immediate pest control but also align with sustainable ecological principles. The review underscores the importance of traditional practices like crop rotation, flooding, etc. providing a comprehensive overview of indigenous knowledge. However, amidst their effectiveness, these practices face the peril of extinction due to insufficient documentation and limited integration into mainstream research. The study advocates for a concerted effort to protect and promote these indigenous practices, not only for their role in sustainable plant protection but also as vital elements of Nepal’s cultural and agricultural heritage.

“…[13] The continued overuse of pesticides for the protection of medicinal plants from insect and disease attacks could affect consumers' health when they are consumed. [14,15] It is perhaps unsurprising that high levels of pesticide residues have been detected in some raw medicinal herbs. [16,17] The literature claims that chronic exposure to numerous pesticides with distinct mechanisms results in brain damage, depression, diabetes, and respiratory conditions including rhinitis.…”

Medicinal plant safety is a rising challenge worldwide due to the continued overuse of pesticides to their maximum residue limits. Due to the high demand for medicinal plants, their production is being increased and sometimes protected by pesticide use. The analysis of these residues requires robust analytical methods to ensure the safety and quality of medicinal plants. Developing effective sample preparation for detecting pesticides is challenging, due to their diverse natures, classes, and physico‐chemical characteristics. Hence, existing techniques and strategies are needed to improve the reliability of the results. The review discusses the current state of sample preparation techniques, analytical methods, and instrumental technologies employed in pesticide residue analysis in medicinal plants. It highlights the challenges, limitations, and advancements in the field, providing insights into the analytical strategies used to detect and quantify pesticide residues. Reliable, accessible, affordable, and high‐resolution analytical procedures are essential to ensure that pesticide levels in medicinal plants are effectively regulated. By understanding the complexities of pesticide residue analysis in medicinal plants, this review article aims to support the conservation of medicinal plant resources, promote public health, and contribute to the development of sustainable strategies for ensuring the safety and quality of medicinal plants in Nepal. The findings of this review will benefit researchers, policymakers, and stakeholders involved in the conservation of medicinal plant resources and the promotion of public health.
