Global warming is the gradual rise in earth’s surface temperature due to the effect of greenhouse gases released from burning fossil fuels and deforestation. Over the period of 1880-2012, the combined land-ocean temperature increased by 0.85° Celsius. Global average temperature is expected to rise between 1.4 – 5.8°C in the next 100 years.
A recent report by Intergovernmental Panel on Climate Change (IPCC) confirmed that human activities are ‘dominant cause’ of global warming since 1950s (IPCC, 2014).The climate change alters hydrological systems through precipitation change or melting of snow or ice and affects the quantity of available water, seasonal activities, and migration patterns.
In this post, I focus on global warming’s consequences in South Asian regions and the imminent need to collaborate to identify and reduce climate change related risks.
Serious Consequences of Global Warming
Power wastage amounts to 50m units due to lack of transmission lines (The Kathmandu Post, accessed September 4, 2013)
I have raised the issue about the consequences of lack of transmission infrastructure in Nepal. NEA reports that the total loss due to insufficient transmission lines in 2012-13 fiscal year is worth of Rs 420 millions. The posts cites Bhuwan Chettri, chief of Load Dispatch Center (LDC), and writes that NEA’s loss was due to the delay in construction of three power line projects, including Khimti- Dhalkebar (220kv), Suchayatar-Matathirtha-Kulekhani – 2 (132kv) and Bharatpur-Hetaunda (220kv). The delay affected power generated from hydro power projects like Kaligandaki, Marysandi, Madhya Marsyandi, Trishuli, Chilime, Indrawati and Spring Khola to connect to the national grid. The news reiterates the fact that Nepal should focus on building new transmission and distribution lines to accommodate additional generation if it seriously wants to solve the energy crisis.
Power Grid preparing road map for SAARC electricity grid (The Economic Times, accessed August 30 2013)
This is a very welcoming news indeed. An electricity grid connecting South Asian countries will not only increase reliability, but also will help to harness each SAARC nation’s capacities and resources to address growing energy needs in the region. India, Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, Pakistan and Sri Lanka are part of SAARC. The Indian State-run Power Grid is finalizing the construction of transmission line between India and Nepal for transfer of bulk power.

Nepal’s energy situation is marred with massive power shortages. Besides low production of electricity, the other cause for the shortage of electricity is the amount of power lost during the transmission and distribution process. The average annual transmission loss in Nepal’s electricity market is about 28 percent of total electricity generation (Nepal Electricity Authority, 2011), whereas the average power loss among 134 countries that are in World Bank’s database is 13.67%.
Reducing transmission loss is very important because the saved power can be sold to consumers and thus can generate extra revenue. It is even crucial in Nepal’s case, since we have not been able to produce enough electricity to meet the demand. Thus, decreasing transmission losses not only generates additional revenue, it can also be an alternative for saving capital cost from building new infrastructures.
