Adaptation Mechanisms in Agriculture for Climate Change in Nepal

摘要

In Nepal, impacts of climate change can be observed in varying levels of climate that are prevalent in diversified topography and vegetation. Broadly speaking, there are impacts of climate change in the Terai lowlands, the mid-hill valleys and mountains, and in the high Himalayas. Nepal is a unique climatic laboratory for studying the impacts of climate change. Sixty-five percent of the Nepalese people engage in agriculture and more than 32% of Gross Domestic Product (GDP) comes from it. There are evidences of climate change in frequently changing monsoonal patterns resulting in droughts, floods, landslides, and other unexpected results that impair subsistence agriculture systems in the country. As a result, there is chronic food shortage in remote hills, and in the mountains, and the Terai, the grain bowl of Nepal, has been hit by food shortage. To date, around 3.9 million people have suffered from hunger and poverty. There are reports that major food crops of rice, maize, and wheat production have declined due to changes in monsoon patterns, insurgence of new pests, and decline in soil productivity. Efforts have been initiated to adopt drought and pest tolerant varieties, changes in planting time, and method of plantings as strategies for adaptation to climate change in agriculture. This paper attempts to highlight adaptation as a strategy to address issues of climate changes from the perspective of Nepalese agriculture.
