Climate Change, Its Impact And Adaptation In Nepal

The climate on Earth is changing, this is undeniable. Presently, climate change is a major concern for the whole world, and Nepal is no exception. Everyyear, international conferences are held and billions of dollars are spent on tackling this global issue. Those of you who don’t know about the climate and how it is changing, don’t worry. I’m here to open your minds.

Climate refers to a typical weather pattern of a place over a long period of time. Alternatively, it may also be understood as the summation of weather conditions over a large area and long time. Meanwhile, the weather describes the state of the atmosphere right now.

The term ‘Climate Change’ refers to a long-term change in temperature and precipitation patterns resulting in altered climatic conditions. According to data, Nepal is the 4th most vulnerable country to climate change. According to the National Adaptation Program Of Action (NAPA), 29 districts in Nepal are prone to landslides, 22 districts to droughts, 12 districts to flooding, and 9 districts to GLOFs.

There are two causes of climate change which are explained below:-

Causes Of Climate Change

Natural Cause:

The Earth’s climate is changing naturally, but at a slow rate. The effects of natural causes are not catastrophic. Natural climate change has been occurring since the beginning of time and living organisms can easily adapt to it.

Anthropological Cause:

Climate change is accelerated by human activities. Our climate is being negatively impacted by urbanization, industrialization, GHG emissions, deforestation, and unmanaged waste deposition. Recent data indicates that Nepal’s greenhouse gas emissions have doubled from 13,447 gigagrams to 28,166 gigagrams per year. Some GHGs are Carbon dioxide, Carbon monoxide, Methane, Nitrous oxide, CFCs.

Impacts Of Climate Change

Climate change has impacted a wide range of areas. In this article, we will focus on the impact of climate change on agriculture. Some of the impacts are listed below:-

1. Impact On Temperature

The temperature is increasing day by day due to climate change. The mean annual temperature in Nepal is increasing by 0.06°C per year. The graph below illustrates the pattern of rising temperatures in Nepal.

Climate change Impact on Temperature in Nepal

This temperature rise has both positive and negative effects on Agriculture:-

Negative Effects

•Decreasing surface water: As the temperature rises, evaporation increases. This is causing small rivers to dry up. As a result, Irrigation is hindered, and many people are forced to deal with droughts and desertification.

•Less Production: When the temperature increases, the maturation time for a crop decreases, which leads to less production. Furthermore, with less water available, the plant can’t give the best results.

•Farmers cannot work in the field due to high temperatures. Normally, we were able to work easily during June/July, but now with intense heat we are unable to do so.

•Farm animals, especially exotic animals like the Toggenburg goat, suffer from heat stress. As a result, their production decreases, and a farmer is forced to bear the loss.

•Another serious impact of climate change is on Himalayan peaks. The ice is melting at rapid rate. The Himalayan peaks used to be covered in snow before (10-20) years ago. Nowadays, it is rare to see snow on them. The Himalayan peaks appear as rocks.

•With 1°C increase in temperature, 20% snow is lost. This results in glacial lake outburst flood(GLOFs). Nepal has experienced 24 GLOFs in the past which has caused huge damage to the Animal, People and Economy. The temperature rise in Himalayan region is more rapid which can be seen in the graph below:-

Positive Effects

As temperatures rise, the varieties previously unable to grow at high altitudes can now be grown since they aren’t subject to chilling injuries.

2. Impact On Rainfall

We can see that Rainfall pattern has become unpredictable over the last few decades. The timing, amount, and distribution of rainfall have all changed significantly. The rainfall has become erratic. Numbers show that mean annual rainfall in Nepal is declining by 3.7 mm per decade.

Effects Of Unpredictable Rainfall

•Agricultural production in Nepal is largely dependent on Monsoon rains. Farmer’s are unable to prepare for paddy cultivation due to unpredictable rain.

•Loss of fertile topsoil. Every Year, 60 cm of topsoil is swept to Bangladesh from Nepal.

•Rainfall And Hail During Harvesting Time Cause The Loss Of Already Produced Grains

•Flood And Landslides: Every year Due To Erratic Rainfall, Flood and Landslides occurs which destroys human life, Properties and Thousand Hectare Of Agricultural Land.

3. Insects And Pest Outbreak

Different kinds of pests increase due to climate change. Climate change is responsible for the desert locusts seen in India and Nepal in 2020. These pests are extremely destructive. They consume our Crops, Fruits, Foliage. Not only new pests, Climate Change contributes to increase the metabolism of insects which cause more destruction of crops. With 10 °C Increase In Temperature, Metabolic Rate Of Insects and Pests Doubles Meaning They Consume More Agricultural Crops

4. Impact On Economy And Livelihood

66% of Nepalese are directly or indirectly involved in Agriculture. With climate change, They aren’t able to get maximum production which is making it difficult to solve hand to mouth problems especially for marginal farmers. Flood And Landslides Swept Away The People’s House, Farm Animals and Other Properties leading To Mass Migration. The Government Of Nepal is allocating a huge amount of Budget to address Climate Change. (NRS. 393.33 Billion Spent In Year 2017/18).

Adaptation On Farmers Level

Despite the change, people still need to survive. The Earth is our home. It should be protected. We should adapt according to the changing situation. People are using different new and innovative ideas to tackle with changing climate. Some adaptation on farmers level are listed below:-

•Climate Resilient Varieties :Climate-resilient Varieties are the crop varieties that have enhanced tolerance to biotic and abiotic stresses. For Example: Drought Tolerant, Submerged, Salt Tolerant and Early Maturing Varieties.

For Example:- Bheri-Ganga, Borlaug-2020 are Climate resilient Varieties Of Wheat and Sukha Dhan 1,2,3,4,5 (Rice Varieties)

•Use Of Techniques Like Drip Irrigation and Collection Of RainWater To Prevent Water Shortage In Peak Time Of Farming

•Use Of Greenhouse Technology, IPM, INM, Crop Rotation, Organic Farming, Conservation Agriculture, Sustainable Agriculture.

•Intercropping:- Preserve Loss Of Top Soil and Helps To Do Farming On Slope Areas

Some adaptation program from national level are:-

Government of Nepal is allocating high budget to tackle with climate change problem. They are encouraging the people for organic farming and for the conservation of natural resources. Government in cooperation with different NGos and INGOs has formed different Policies regarding climate change. For eg: Nepal’s Climate Change Policy (2011) Revised In 2019

Some organisations working for mitigation of climate change in Nepal are listed below:-

✓Li-Bird (Local Initiatives For Biodiversity, Research and Development)
✓WWF Nepal

Some programs regarding the climate change in Nepal are:-

Hariyo Ban Program

Hariyo Ban Nepal is a Program contributing to reducing the effects of climate change at community level. It is an approach set up with the combined efforts of WWF, CARE, NTNC and FECOFUN. This program was initiated on 15th July, 2016 as a five year program plan. It mainly works on Biodiversity Conservation and Climate Change Adaptation.

Climate Smart Agriculture (CSA)

Climate smart Agriculture is another great way of adaptation with changing climate. It is a holistic approach of managing and changing the agricultural activities according to the changing environment. Some CSA approaches are:-

✓Change in traditional agricultural practices.

✓Integration of modern technologies in agriculture to increase water, nutrient and input use efficiency.

✓Integration of digital media to disseminate the Information rapidly. It helps to alert the farmer about the possible loss.

Climate change is real. It will be a major issue in the future. We must be prepared for a devastating future if we do not take the right steps at present. Government and organisations do not have all the responsibility to solve this issue, we at the individual level also need to take part. In Nepal, Agriculture is the main source of livelihood. As a result of climate change, Agriculture is facing huge problems. Therefore, farmers should be made aware of climate smart agriculture.
