Nepal, a country of beautiful snowcapped mountains, lakes, rivers, water sources, forest and is popular tourism destination for its nature, scenery and ecology. Despite its relatively small area, Nepal has very diverse climatic conditions, ranging from tropical in the south to alpine in the north. Nepal contributes only 0.027% of the total green house gases globally, Nepal has been highly vulnerable to the climate related disasters due to its climate and geography. Nepal¡¯s changing climate impacts the country¡¯s main ecosystems (forests, grasslands, rangelands, wetlands, mountains and agro-ecosystems). Temperature and Precipitation We have been experiencing high temperature than last decades with high temperature making new records each year. There is projection of rise of 1.6 to 2.2-degree Celsius temperature by 2050. The precipitation pattern has changed in Nepal with erratic rainfall pattern with heavy rainfall and long drought period. With heavy rainfall during the rainfall we are experiencing more disasters like flood and landslides. climate change is responsible for a drastic, yet often erratic, changes in seasonal water availability, resulting in drought conditions during the dry season and increased flooding during monsoon. The climate prediction suggests 3.9 to 5. 1 % increase in annual precipitation along with increase in consecutive dry days. There can be increase of 35-52% increase in extreme rainfall events by 2050. Agriculture: Increased variability in weather, extreme condition changing crop weed competition dynamics, increase in pests and diseases, decreased biodiversity owing to temperature and climate change affect agricultural productivity resulting in food insecurity. Nepal is an agrarian nation with Agriculture GDP contributing almost 27% to total GDP and 60% people being involved in the agriculture. Highly diverse nature of agriculture, high rainfall dependency, inadequate infrastructure facilities for supply of quality input, rapid degradation of soil and loss of fertility and nutrient level, and poor resources base of the farmers has made agriculture highly vulnerable to climate change. Nepal¡¯s agriculture is facing risks due to changes erratic monsoon rainfall and flooding. About 64% of cultivated areas are fully dependent on monsoon rainfall. Decline in rainfall from November to April adversely affects the winter and spacing crops. Rice yields are sensitive to climatic conditions. IPCC 4th Assessment Report estimates that crop yield in South Asia can decrease by up to 30% by 2050. Climate Induced Disasters Climate induced disaster and their further consequences can be as the indirect effect of climate and besides direct impacts of direct of climate change there are many other indirect impacts of climate change that might affect Nepal and its people severely. Nepal has been experiencing the increased number of climate related disasters like flood, landslides, glacier outburst and forest fire. Flood: Floods in Nepal are particularly associated with summer monsoon rains, and are a feature of current climate variability. The country's more than 6,000 rivers and rivulets, with a total of 45,000 km in length. In most cases, climate change is projected to increase the intensity and frequency of high flows, and increase flood risks in Nepal. Landslides: It is another climate induced hazard which are often related to extreme rainfall or flood events. Landslides also have significant impacts on communities and infrastructure. Nepal is a country of uneven terrain and people of hills and mountainous region are consider to be vulnerable to landslides. Drought: Due to climate change some part of the country might get excessive amount of rain while other part might suffer from drought. Increasing temperature might trigger drought event. Forest fire: An increase in the frequency and intensity of droughts, if coupled with extended forest cover, will greatly increase the risk of forest fires. Glacial Outburst: Nepal¡¯s Himalaya, total estimated ice reserve between 1977 and 2010 decreased by 29%. 20% of loss of snow and glaciated area with 1¡ÆC increase in temperature increasing glacial lake outburst and flooding. With increasing temperature and melting of snow, many glacial lakes of Nepal pose threat in Nepal. Climate Change Policies in Nepal Government of Nepal has implemented policies related to climate change to reduce its impact and help in adaptation and mitigation process of climate change. The climate policies of Nepal are: Climate Change Council, 2009, chaired by the Prime Minister Climate Change Management Division, 2010, Ministry of Environment National Adaptation Programme of Action, 2010 Climate Change Policy, 2011 Climate Resilient Planning Tool , 2011: National Planning Commission Local Adaptation Plan of Action (LAPA), November 2011 Intended Nationally Determined Contributions, 2016 References: Dixit, A.

Greetings kushal dai
I hope you are doing well
Thank you so much for sharing it.
Indeed ecosystem is highly affected by this change in climate. I hope it gets addressed.
Green Cheers

Thank you mentor. The topic is very much of my interest as well

Hello Kushal!
It's your SJ mentor.
I'm very surprised that you just finished your article in this short period.
Thank you for sharing ongoing natural phenomenon in Nepal due to climate change.
Also East Asia countries are also suffering from climate change.
Heavy rainfall hit China, Japan and Korean in this summer.
In Korea I experienced such a long rainy season about 54 days.
It's the longest record after weather observation.
I think whole nations should do our best to prevent climate change from now on.
Let's think about the concrete example to put off this issue.
Green cheers!

Greetings
Thank you for sharing a informative about effect of climate change on ecosystem. Due to flood,landslides many people lost their lives . Government and individual should aware to mitigate climate change.
Keep writing such informative report.
We are eager to know more from you.

I love Nepal and would love to visit there one day. It is known for its possession of mountainous landscape including Mount Everest which is the tallest in the entire world! But as you've rightly highlighted, Climate Change has been a thorn in the country's flesh and we hope that things would be much better as time moves on.
Green cheers!

Thank you malika. We must work together for adaptation and mitigation

Thank you Mentor. Climate change is creating a serious hindrance to many field already and we must take climate action for its adaptation and mitigation.

Hello Kushal, this is your mentor WooJoo :)
Announcement of the topic of the month was made just few hours ago, and you already wrote a report! Wow :O I'm impressed by your speed!
Decreasing biodiversity and increasing pest would be really badly affecting your country and agriculture. South Korea has been suffering from drought for years, but this year it rained too much that destroyed agricultural area :( I wish everyone noticed how climate is changing and be aware of the environmental situations, which are quite serious.
Thank you for the first thematic report. Keep working hard!
Green cheers! :)
Best wishes,
