“…Additionally, approaches and tools allowing for a riskbased evaluation and prediction of the forest's protective effect in future should be promoted and further developed. Furthermore, there should be a concerted effort to promote and further develop approaches and tools that allow a risk-based evaluation and prediction of the protective effect of forests in the future (e.g., Moos et al, 2018;Stritih et al, 2019;Chabba et al, 2022;Teich et al, 2022b).…”

Forests in mountain areas provide an indispensable ecosystem service by protecting people and infrastructure against natural hazards. As forests are increasingly affected by global change, including climate change, more frequent and severe natural disturbances, and shifts in land use, open questions remain regarding the long-term and sustainable provision of this crucial protective service. To improve our understanding of the various effects of global change on protective forests, we summarized the current knowledge based on a systematic review. Focusing on changes in mountain forests’ protective effect against snow avalanches, landslides, rockfall, torrential floods and debris flow, we assessed 72 peer-reviewed, English publications. Overall, climate-induced changes are expected to increase forests’ protective effect at higher elevations but reduce it at lower elevations mainly due to increased drought. Natural disturbances usually decrease the protective effect of forests, and their impact is often further exacerbated by salvage logging. Different forest management strategies are often studied using forest simulation models, and their impacts on protective forests strongly depend on the local context and interactions with climate change. While clearcuts consistently reduce the protective effect, other forest management interventions such as thinning can have either positive or negative effects. Most of the reviewed studies were case studies based on forest simulation or process-based hazard models (but rarely combining the two), while empirical evidence was scarce. Forests’ protective effect is often assessed using (diverse) indicators of forest structure, but evaluations of resulting risks are less common. More consistent modeling approaches linking forest structure to hazard and risk, as well as consistent indicators across different case studies, are needed for a better understanding of changes in protective forests and the service they provide under global change.

“…A BCR greater than 1 indicates a thriving production with economic potential, where the expected financial returns exceed the resources invested. Conversely, a BCR below 1 raises cautionary flags, akin to a grove plagued by neglect or disease (Chabba et al, 2022). It serves as a stark reminder that the costs of wheat production may exceed the expected returns, prompting a reassessment of farming practices or market strategies.…”

Wheat (Triticum aestivum L.), a staple crop in Nepal, has a rich history of cultivation. Despite increasing demand due to population growth and agricultural development efforts, wheat production faces persistent challenges that hinder its expansion and profitability. This research, conducted from February to July 2022 in West Nawalpur district, Nepal, aims to assess the productivity, profitability, and economics, including benefit-cost analysis, of wheat in West Nawalparasi. A total of 100 wheat farmers were selected and the data obtained were analyzed using Microsoft Excel and Statistical Package for the Social Sciences (SPSS). The study reveals a positive gross margin (NRs 1113.09) and a benefit-cost ratio (BCR) of 1.6 per 0.3 hectare, indicating the profitability of wheat cultivation. Notably, most farmers procure agricultural inputs such as seeds and fertilizers from local agro-dealers within Nepal, highlighting a preference for domestic sources over imports from India. For irrigation, more than half of the population relies on pumps that draw from open water sources (59%) and use mechanization equipment such as tractors and combine harvesters for field activities. However, the study reveals the complexity of the challenges faced by wheat farmers. Chief among these are the unavailability of adequate irrigation facilities, untimely and inadequate access to agricultural inputs, disease and pest incidence, lack of training and extension services, and lack of mechanization and skilled labor. These constraints, as highlighted by the farmers, affect both productivity and profitability, highlighting the urgent need for initiatives to reduce production costs and improve wheat production in West Nawalparasi.

“…This signifies that the anticipated financial returns from the cultivation of acid lime exceed the resources poured into their production, akin to a citrus grove laden with ripe marketable fruits. Conversely, a BCR dipping below 1 raises caution flags akin to a grove suffering from neglect or disease (Chabba et al, 2022). This serves as a stark reminder that the costs incurred in lime production may outweigh the expected returns, prompting a reevaluation of cultivation methods or market strategies.…”

Acid lime plays a crucial role in the livelihoods of many Nepali farmers and holds substantial promise for local economic development. This study analyzed the economic aspects of acid lime production in three municipalities of the Nawalpur East district of Nepal: Madhyabindu, Bulingtar, and Bungdikali, and sought to identify the concerns and potential related to acid lime marketing and manufacturing. Data were gathered from 96 acid lime producers using a semi-structured questionnaire from May 2022 to July 2022. The average areas of acid lime cultivation and productivity were 0.387 ha and 3.061 mt ha-1, respectively. The production cost of acid lime was Rs. 104.82 kg-1. The rental values of land and labor costs (p=0.30) were the highest influencing elements at 35.99% and 19.71%, respectively. Other analyzed factors included the cost of fertilizer (p=0.20), plant protection (p<0.01), Bordeaux-micronutrients (p=0.35), and farm management (p=0.18). Benefit-cost analysis revealed a ratio of 0.80 and mean gross margin of Rs. -19.82 for acid lime production. The major problem for the production of acid lime was the lack of irrigation, whereas the lack of storage was found to be a major market problem and thus needed careful attention from the relevant authorities. This examination indicated that acid lime production is a practical choice for Nepali farmers in the countryside; however, there is a need for improvement in production management. This also suggests that acid lime farming has the potential to become a successful export-focused business in the long run in the Nawalpur East district of Nepal.
