Khumbu Since 1950


A photograph captures an instant. But we can represent time and the change it brings by repeat photography. Pictures taken decades, or even a century apart, show us how the world has changed and is changing. Nowhere is before-and-after photography as dramatic as in portraying climate change, urbanisation and the rapid transformation of a culture.

Alton Byers is a mountain geographer, conservationist and mountaineer specialising on the impact of climate change in high altitude areas. He did his PhD on the changing vegetation of the Khumbu, and knows the area well, both the good and bad of how the region has been transformed by tourism, rising living standards and, lately, global warming.

Byers has chosen repeat photography as the ideal medium through which to document change. "It provides an extremely effective educational tool that quickly and dramatically illustrates changes in glaciers, forest cover and cultural landscapes over time," Byers says.

Indeed, his slim new volume Khumbu Since 1950 does just that: tell the visual story of how much the land of the Sherpa people has changed in the past 70 years. The region is better documented in photographs than other parts of Nepal because the first mountaineering expeditions to Mt Everest started arriving in the early 1950s. Global warming has been so rapid that even in that short span of time (in a planetary, geological frame) one can see shrinking glaciers, receding snow lines, scars of flashfloods, increased forest cover in some places, and how mountaineering income has raised living standards and led to the visible growth of Namche Bazar, Tengboche and other towns.

Byers sourced old photographs from Charles Houston who was the first western climber to visit the southern approaches to Mt Everest in 1950. He collected images from John Hunt and Charles Evans both from the 1953 British Expedition, as well as the Austrian climber-cartographer Erwin Schneider's glacial panoramas from 1955.

Interestingly, Schneider's maps of the Everest region from that period show glaciers where today there are large lakes like Imja. There are also rare photographs of the Khumbu Glacier from Swiss-Canadian glaciologist Fritz Müller who was part of the Swiss Mt Everest Expedition in 1956. Byers himself first visited the region in 1973 and has his own archival photos from that visit.

Repeat photography essentially means going to the same photopoint where the original picture was taken, in the same season, at the same time of day, in similar weather and shoot an 'after' picture of the same place. The findings were dramatic in more ways than one. The thinning of snow and ice cover was, as expected, the most visible. However, contrary to the scientific consensus of the time, it looks like the Khumbu had not suffered much denudation of vegetation, in fact the book shows some dramatic increase in forest cover after the Sagarmatha National Park was set up and after local conservation initiatives took effect.

Byers will be donating the book to schools, monasteries and community groups in the Khumbu region. He is also returning next year to train two Nepali and US graduates in repeat photography methods who can replicate other archival photos, and interview local people to find out about the changes. The book is being launched in January 2018 in Kathmandu, and the captions are to be translated for a Nepali edition.

DHL Receiver’s Guide to Duties and Taxes, Goods Purchased Online for Personal Use
You may be charged customs duties and taxes for something purchased online because:

Duties and taxes are most typically not included in the price of the goods you purchase online, and might not be included in the overall shipping costs you pay to the online retailer.
When purchasing goods online, some or all of these goods may not originate in the country you reside in, therefore are subject to a customs duty, which is a tariff or tax imposed on goods when transported across international borders.
When goods are not shipped domestically (within your country) or within a single customs union, such as the European Union, you are liable to pay any inbound duties and taxes which your local customs authority deems appropriate.
To ensure the DHL courier can deliver your goods in shortest possible time after entering your country or customs union, DHL pays the customs authority on your behalf for any duties and taxes that are due on the goods.
Once the duties and taxes are fully repaid to DHL the goods will be delivered to you What is payable, if anything, depends on where the goods are sent from, the type of goods, their transactional value and the weight of the package
