木斯塘是尼泊尔西部卡利甘达基河流域的一个山区，气候变化越来越多（例如，更高的温度）。气温上升导致生态变化，反过来又会导致该地区苹果树种植下限的扩大。苹果种植可以通过减少脆弱性、收入来源多样化、改善生计和农民能力建设，为适应气候变化提供机会。由于缺乏强有力的基础来证明扩大苹果种植在野马，本研究探讨了该地区的苹果种植的生物物理和社会经济适用性。从第一手和第二手来源收集了必要的数据和资料。生物物理适宜性的调查结果使用可变和相等的权重的指标显示，5.2%和4.1%的地区是非常适合苹果种植，分别。然而，并非所有潜在的农业区目前都在使用中。因此，有可能将苹果种植扩大到未种植的地区，并将苹果作物与耕地上的其他作物相结合。气温升高可能会增加未来几年苹果种植的适宜区域。土地利用的高效益成本比证实了苹果种植与其他土地利用相比的经济适宜性。社会适应性评估显示，没有社会不和谐，冲突，或与苹果种植的分歧，这是一个积极的指标，在尼泊尔西部的苹果种植的扩展。
Mustang, a mountainous region in the Kali Gandaki River Basin in western Nepal, has been increasingly experiencing climatic changes (e.g., higher temperatures). Rising temperatures lead to ecological shifts, which, in turn, can lead to the expansion of the lower limit for the cultivation of apple trees in this area. Apple cultivation can provide opportunities for adaptations under climate change through vulnerability reduction, income source diversification, livelihood improvement, and capacity building for farmers. As there is a lack of a strong basis to justify the expansion of apple cultivation inMustang, this study examines the biophysical and socioeconomic suitability of apple cultivation in the area. Necessary data and information were collected from both primary and secondary sources. Findings of biophysical suitability using variable and equal weights to the indicators showed that 5.2 and 4.1 % of the areas are highly suitable for apple cultivation, respectively. However, not all potential farming areas are currently in use. Thus, there is the possibility to expand apple cultivation into unplanted areas and to integrate apple crops with other crops on cultivated lands. Increasing temperature may increase the suitable areas for the cultivation of apples in the coming years. High, benefit–cost ratio for land use confirmed the economic suitability of apple farming when compared to other land uses. The social suitability assessment showed no social discords, conflicts, or disagreements with apple cultivation, which is a positive indicator for the expansion of apple cultivation in western Nepal.
