Alton C Byers and Lhakpa Sonam Sherpa have teamed up to expand, update, and improve the first edition of Khumbu Since 1950 published in 2017. The result is a first-rate photographic documentation of the dramatic changes which have occurred in the villages, forests, and glaciers of the Mt Everest region over the past 73 years.&nbsp; Both the historic and recent photo replicates are of excellent quality, and even the more than 70-year-old enlargements acquired from contact prints of 35-mm negatives appear remarkably clear (it was necessary to use the prints of the negatives because the negatives themselves had been lost).&nbsp; Their own replicas of the historic photographs are outstanding, especially considering that taking them required many hundreds of kilometers of trekking, and thousands of meters of climbing, even some serious semi-technical mountaineering, in search of the exact locations from which the historic photographs had been taken, as far back as 1950 and the first visits by westerners to Khumbu.&nbsp; The photographs have been expanded from the original 133 to 228, many of them never before published and taken by the first western climbers, climber-scientists, anthropologists, and development workers to have visited the region (the lack of historic photographs taken by Sherpas reflects the lack of personal cameras at the time).&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20231114041140_2e0b1e0557d5b1d77d58d06db8ebd4539b79c1f893726196d23020c4f0cee754.jpg" data-media-id="editor_0" data-image-id="20231114041140_2e0b1e0557d5b1d77d58d06db8ebd4539b79c1f893726196d23020c4f0cee754" data-rendition-name="original" width="3000" height="2770" loading="lazy" alt="Khumbu NT"> <figcaption>Namche Bazar in 1976 when hardly 1,000 tourists per year were visiting Khumbu.

It follows that the photographic collection is of vital importance as a historical document, and in the words of Lhakpa Norbu Sherpa “…could very well serve as the foundation for future monitoring, and subsequent management, of the Sagarmatha National Park and Buffer Zone’s changing cultural and physical landscapes”. Byers and Sherpa introduce us to many of the early pioneers of mountaineering, survey, and conservation in the Khumbu.

Dramatic changes in villages, from sleepy traditional communities to bustling international tourist centers, are illustrated in dozens of repeat photographs.&nbsp; The rapid regeneration of Khumbu’s subalpine forests over the past 50 years is clearly evident in a number of different photo pairs, and challenge the hypotheses of ‘deforestation in the Khumbu’ so popular with developers in the 1970s and 1980s. The loss of the region’s snow, ice, and glaciers is particularly sobering, captured by the repeat photograph of cartographer Erwin Schneider’s 1956 image of a debris-covered glacier, which has now turned into a glacial lake containing some 91 million cubic meters of water.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20231114041140_a713c7c529a865f2ec7b01cd7b663f5479f3bae91c482096e481ac12be57fc49.jpg" data-media-id="editor_9" data-image-id="20231114041140_a713c7c529a865f2ec7b01cd7b663f5479f3bae91c482096e481ac12be57fc49" data-rendition-name="original" width="3093" height="1000" loading="lazy" alt="Khumbu NT"> <figcaption>Imja’s debris covered glacier in 1956 was typical of most large glaciers in Khumbu, a sign of glacial stagnation since the end of the Little Ice Age around 1870.

Its calving rate between 1992 and 2002 was 36 m/yr, and between 2002 and 2012 accelerated to 52 m/yr.  Imja is the most studied glacial lake in Nepal if not the world, and has been the source of considerable controversy over whether it is dangerous or not in terms of a glacial lake outburst flood.  Most scientists now agree that while the lake may not be dangerous at present, within 10 to 20 years it could pose a serious risk to downstream communities when the lake lies directly underneath the overhanging ice of the mountains at its head. The lake was lowered by approximately 3m in 2016 by the Nepal Army.

Photo: ALTON BYERS</figcaption> </figure>  Many good things have resulted from tourism and the modernisation of Khumbu, several of the consequences remain chronically troubling. Thousands of tons of plastic, aluminum, electronic, medical waste continue to be burned and buried each year in the hundreds of landfills that now pockmark the region, poisoning the air, water, people, and animals that live there.&nbsp; In spite of nearly 200 years of mountaineering history throughout the world, strategies to effectively manage human waste at high altitudes continue to elude the mountaineer and development practitioner alike. Khumbu Since 1950 is thus a reminder that, in spite of much progress, much work remains to ensure a thorough collaboration between the local mountain people and visiting supporters toward sustainable mountain development. Khumbu Since 1950 is a vital visual tool that will be appreciated and used by visitors, scholars, government, and development workers alike for years to come. The fact that it can now be updated by future Nepali scholars interested in the positive and negative aspects of change over time makes the book all the more valuable.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20231114161128_dfba8a4d937fca9c210065170694c9279c1186748f05a00d55cb5027b96d7a03.png" data-media-id="editor_12" data-image-id="20231114161128_dfba8a4d937fca9c210065170694c9279c1186748f05a00d55cb5027b96d7a03" data-rendition-name="original" width="1153" height="519" loading="lazy" alt="Khumbu NT"> </figure>  Jack D Ives is with the Department of Geography and Environmental Studies, Carleton University Ottawa, Canada. <a href="mailto:JackIves@Cunet.Carleton.ca">JackIves@Cunet.Carleton.ca</a>

The reservoirs that served the city were almost empty. Fortunately, rains and lowered water use helped avert the crisis. A year later, Chennai, India’s sixth largest city, came near to Day Zero, too. Last minute rains again eased the emergency.In 2015, Chennai faced devastating floods. How could a region that was submerged four years earlier suffer such a serious water crisis? Despite <a href="https://www.nepalitimes.com/banner/nepal-tarai-learns-from-past-floods/" target="_blank" rel="noopener">floods</a> and droughts becoming a regular feature of South Asia’s climate, none of our governments have learnt lessons to conserve, <a href="#967 July 5dataews.php?id=17425" target="_blank" rel="noopener">harvest and store</a> water. Misuse and inefficiency are high, and precious water is blatantly abused.Urbanisation, <a href="https://www.nepalitimes.com/here-now/pokharas-shrinking-lakes/" target="_blank" rel="noopener">encroachment of lakes</a>, <a href="http://archive.nepalitimes.com/news.php?id=18976#.XR3p0-szaUk" target="_blank" rel="noopener">wetlands</a>, ponds, and open spaces that served as flood buffers have made inundation worse on one hand, while depleting natural storage systems at a time when water runs out like now. As Chennai expanded with new industries and IT-led growth, the wetlands were converted into housing.In January 1995, 40 hydro-geologists, social scientists, water analysts, economists, political scientists and agriculturalists had gathered in Chennai to discuss the political economy of water in South Asia. The conference, convened by the US Social Science Research Council, had concluded that relatively wealthy middle class urban domestic users appeared to have top priority over water, industries get next priority, irrigation users are next and rural domestic water users and the urban poor are at the bottom of the rung.Twenty-five years later, nothing seems to have changed. In fact, this <a href="https://archive.nepalitimes.com/article/nation/Melamchi-water-not-enough-for-everyone,3899" target="_blank" rel="noopener">hierarchy of access to water</a> is now even more entrenched, and continues to promote the transfer of pumped water from rural to urban areas. Extraction rates <a href="https://nepalitimes.atavist.com/recharging-the-mountains-" target="_blank" rel="noopener">exceed recharge and groundwater storage</a> is gradually depleted.Water problems in India, Nepal and the rest of the subcontinent are a result of a complex interaction among urbanization, agriculture, industries, changing water use, and impact of the climate crisis on  precipitation, rising temperature and humidity. By 2030, 40% of South Asia’s population will be living in cities. Urban settlements require more water supply in concentrated areas. Rapid urbanisation and the increases in demand bring new challenges as higher income families use more water to meet sanitary functions producing more waste water.The water challenges in Nepal is no different. <a href="https://www.nepalitimes.com/banner/a-terrifying-assessment-of-himalayan-melting/" target="_blank" rel="noopener">Himalayan glaciers and snowpacks are melting faster</a>, the springs in the mid-mountains are going dry at an alarming rate while <a href="https://archive.nepalitimes.com/article/nation/water-table-of-kathmandu-valley-falling-fast-recharge-to-replenish,4100" target="_blank" rel="noopener">groundwater levels are receding</a> in Nepal’s bhabar, Tarai and across the border in India. Collectively these changes will lower base flows with profound implications for water security across the Indo-Gangetic basin.The current crisis is an outcome of the relentless pursuit of a water development and management model that evolved in an era before the climate emergency. It assumed the unlimited availability of water and focused on supply side solutions, without heeding to demand management and improving water governance. This model has dealt with rainfall, river and groundwater separately, neglecting the water cycle and its intrinsic function in nature. This fragmented approach continues.This water management model is not appropriate to deal with the water emergency. We need to change our approach to adapt to monsoon rains becoming more erratic, as they have this year.  Innovative rainwater harvesting practices, promoting a judicious mix of surface and groundwater sources, and managing increasing water demands is the way to go. The Chennai crisis this year will be replicated in Delhi, Patna and Kathmandu.And it is not the quantity of water that is a problem, the poor quality of available water is an equally serious challenge that needs to be solved with low-cost filtration systems for hundreds of millions of underserved families in the region. Disposal of human waste using treated clean water, in particular, needs to be systematically replaced. <a href="https://www.nepalitimes.com/editorial/getting-our-shit-together/" target="_blank" rel="noopener">Untreated sewage pollutes freshwater sources</a> and reduces available supplies. Already dysfunctional water treatment plants significantly push up treatment costs.Solutions must be based on larger societal commitment achieved through regular consultation between individuals, households, the community, the market and the state about water science, supply options, reduced use, and water conservation, and fundamentally re-crafting the institutions that govern and allocate water. Only this can potentially usher in a people-centered water stewardship and management that will include preservation of open spaces, water bodies and aquatic beings.Ajaya Dixit is Executive Director of Kathmandu based ISET-Nepal. His monthly column Climate for Change in Nepali Times deals with the impact of global warming in Nepal and the region.
