Why does mountain agriculture deserve special attention in a Zero Hunger context? Firstly, because hunger remains common in many mountainous areas. While on a global scale, food insecurity has tended to go down, mountain dwellers have fared worse than people living in plains. Secondly, because mountains cover a large part of the world, especially in Asia: the continent hosts more than one-third of the world’s mountains. Many Asian countries are dominated by mountains: for instance, nearly the entire land area in Bhutan is mountainous, and Lao PDR has 89 percent of its land area classified as mountainous or upland – farmers have no option but to derive their livelihoods from mounting agriculture. Thirdly, mountain agriculture can produce a large variety of nutritious foods not normally available from large-scale agriculture practised in the plains. Strengthening mountain agriculture must therefore be set as a priority for achieving Zero Hunger.
