In Ladakh, a cold arid region, subsistence agriculture has been in practice and is associated with livestock rearing in very small-scale stone-built terrace farming. Due to poor resources, public distribution systems, import/mutual exchange of plant materials and higher labour cost, high-altitude default organic farming has become a complex activity where weeds have become a recurrent problem. Moreover, they have become an integral part of fodder resources under small-scale stone-built terraced farming in barren ecosystems for enriching straw with supplementary weedy stuff. As a result, cropped areas suffer severe weed pressure as it requires 4-5 weedings under high-altitude solar radiation. An intensive survey revealed that the majority of weeds constituted of Amaranthaceae, Asteraceae, Poaceae and Fabaceae families, and they varied attitudinally. In this region, weeds are the major associated plant species, limiting the performance of crops in terms of seed quality and yields significantly. Hence, weed menace is overlooked in crops that impact the invasive weedy species to move upward to high altitudes under climate change. Conversely, people across this region have identified many of the weedy species for their day-to-day consumption as green leafy vegetables and for medicinal uses under the harsh climate of the cold arid region. This article describes the weedy species identified in crops and their utilization under low-land holding subsistence agriculture.

印度寒冷干旱地区自给农业的杂草多样性及其传统用途

在寒冷干旱的拉达克地区，自给农业已经在实践中，并与非常小规模的石头梯田养殖中的牲畜饲养有关。由于资源贫乏、公共分配系统、植物材料的进口/相互交换和更高的劳动力成本，高海拔默认有机农业已成为一项复杂的活动，杂草已成为反复出现的问题。此外，它们已成为贫瘠生态系统中小规模石砌梯田耕作的饲料资源的组成部分，以补充杂草来丰富秸秆。因此，作物区域遭受严重的杂草压力，因为它需要在高海拔太阳辐射下进行 4-5 次除草。深入调查发现，杂草主要由苋科、菊科、禾本科和豆科组成，并且它们的态度各不相同。在该地区，杂草是主要的相关植物物种，严重限制了作物在种子质量和产量方面的表现。因此，在气候变化下影响入侵杂草物种向上移动到高海拔的作物中，杂草的威胁被忽视了。相反，该地区的人们已将许多杂草种类确定为绿叶蔬菜，并在寒冷干旱地区的恶劣气候下用于药用。本文描述了在作物中鉴定的杂草种类及其在低地自给农业下的利用。杂草威胁在影响入侵杂草物种在气候变化下向上移动到高海拔的作物中被忽视。相反，该地区的人们已将许多杂草种类确定为绿叶蔬菜，并在寒冷干旱地区的恶劣气候下用于药用。本文描述了在作物中鉴定的杂草种类及其在低地自给农业下的利用。杂草威胁在影响入侵杂草物种在气候变化下向上移动到高海拔的作物中被忽视。相反，该地区的人们已将许多杂草种类确定为绿叶蔬菜，并在寒冷干旱地区的恶劣气候下用于药用。本文描述了农作物中鉴定的杂草种类及其在低地自给农业下的利用。
