The Asian region spans polar, temperate, and tropical climates and is home to over 3 billion people. As the climate warms, many mountain glaciers may disappear, permafrost will thaw, and the northern forests are likely to shift further north. Rapid population growth and development in countries like China and India will put additional pressures on natural ecosystems and will lead to a rapid rise in the release of greenhouse gases into the atmosphere unless steps are taken to curtail emissions.
Fingerprints
1. Llasa, Tibet -- Warmest June on record, 1998. Temperatures hovered above 77�F for 23 days.
59. Garhwal Himalayas, India -- Glacial retreat at record pace. The Dokriani Barnak Glacier retreated 66 ft (20.1 m) in 1998 despite a severe winter. The Gangorti Glacier is retreating 98 ft (30 m) per year. At this rate scientists predict the loss of all central and eastern Himalayan glaciers by 2035.
62. Tien Shan Mountains, China -- Glacial ice reduced by one quarter in the past 40 years.
90. Southern India - Heat wave, May 2002. In the state of Andhra Pradesh temperatures rose to 120�F, resulting in the highest one-week death toll on record. This heat wave came in the context of a long-term warming trend in Asia in general. India, including southern India, has experienced a warming trend at a rate of 1�F (0.6�C) per century.
91. Nepal - High rate of temperature rise. Since the mid-1970s the average air temperature measured at 49 stations has risen by 1.8�F (1�C), with high elevation sites warming the most. This is twice as fast as the 1�F (0.6�C) average warming for the mid-latitudinal Northern Hemisphere (24 to 40�N) over the same time period, and illustrates the high sensitivity of mountain regions to climate change.
93. Taiwan - Average temperature increase. The average temperature for the island has risen 1.8-2.5�F (1-1.4�C) in the last 100 years. The average temperature for 2000 was the warmest on record.
94. Afghanistan - 2001 - Warmest winter on record. Arid Central Asia, which includes Afghanistan, experienced a warming of 0.8-3.6�F (1-2�C) during the 20th century.
95. Tibet - Warmest decade in 1,000 years. Ice core records from the Dasuopu Glacier indicate that the last decade and last 50 years have been the warmest in 1,000 years. Meteorological records for the Tibetan Plateau show that annual temperatures increased 0.4�F (0.16�C) per decade and winter temperatures increased 0.6�F (0.32�C) per decade from 1955 to 1996.
96. Mongolia - Warmest century of the past millennium. A 1,738-year tree-ring record from remote alpine forests in the Tarvagatay Mountains indicates that 20th century temperatures in this region are the warmest of the last millennium. Tree growth during 1980-1999 was the highest of any 20-year period on record, and 8 of the 10 highest growth years occurred since 1950. The 20th century warming has been observed in tree-ring reconstructions of temperature from widespread regions of Eurasia, including sites in the Polar Urals, Yakutia, and the Taymir Peninsula, Russia. The average annual temperature in Mongolia has increased by about 1.3�F (0.7�C) over the past 50 years.
119. Chokoria Sundarbans, Bangladesh - Flooded mangroves. Rising ocean levels have flooded about 18,500 acres (7,500 hectares) of mangrove forest during the past three decades. Global sea-level rise is aggravated by substantial deltaic subsidence in the area with rates as high as 5.5 mm/year.
120. China - Rising waters and temperature. The average rate of sea-level rise was 0.09 +/- 0.04 inches (2.3 +/- 0.9 mm) per year over the last 30 years. Global sea-level rise was aggravated locally by subsidence of up to 2 inches (5 cm) per year for some regions due to earthquakes and groundwater withdrawal. Also, ocean temperatures off the China coast have risen in the last 100 years, especially since the 1960s.
126. Bhutan - Melting glaciers swelling lakes. As Himalayan glaciers melt glacial lakes are swelling and in danger of catastrophic flooding. Average glacial retreat in Bhutan is 100-130 feet (30-40 m) per year. Temperatures in the high Himalayas have risen 1.8�F (1�C) since the mid 1970s.
127. India - Himalayan glaciers retreating. Glaciers in the Himalayas are retreating at an average rate of 50 feet (15 m) per year, consistent with the rapid warming recorded at Himalayan climate stations since the 1970s. Winter stream flow for the Baspa glacier basin has increased 75% since 1966 and local winter temperatures have warmed, suggesting increased glacier melting in winter.
130. Mt. Everest - Retreating glacier.The Khumbu Glacier, popular climbing route to the summit of Mt. Everest, has retreated over 3 miles (5 km) since 1953. The Himalayan region overall has warmed by about 1.8�F (1�C) since the 1970s.
131. Kyrgyzstan - Disappearing glaciers. During 1959-1988, 1,081 glaciers in the Pamir-Altai disappeared. Temperatures in the mountains of Kyrgyztan have increased by 0.9-2.7� F (0.5-1.5�C) since the 1950s.
142. Siberia - Melting permafrost. Large expanses of tundra permafrost are melting. In some regions the rate of thawing of the upper ground is nearly 8 inches (20 cm) per year. Thawing permafrost has already damaged 300 buildings in the cities of Norilsk and Yakutsk. In Yakutsk, the average temperature of the permanently frozen ground has warmed by 2.7 �F (1.5�C) during the past 30 years.
Harbingers
18. Indonesia -- Malaria spreads to high elevations. Malaria was detected for the first time as high as 6,900 feet (2103 m) in the highlands of Irian Jaya in 1997.
50. Philippines -- Coral reef bleaching.
51. Indian Ocean -- Coral reef bleaching (inclues Seychelles; Kenya; Reunion; Mauritius; Somalia; Madagascar; Maldives; Indonesia; Sri Lanka; Gulf of Thailand [Siam]; Andaman Islands; Malaysia; Oman; India; and Cambodia).
52. Persian Gulf -- Coral reef bleaching.
77. Korea -- Heavy rains and flooding. Severe flooding struck during July and August, 1998, with daily rainfall totals exceeding 10 inches (25.4 cm).
87. Indonesia -- Burning rainforest, 1998. Fires burned up to 2 million acres (809,371 hectares) of land, including almost 250,000 acres (101,172 hectares) of primary forest and parts of the already severely reduced habitat of the Kalimantan orangutan.
88. Khabarovsk, Russia -- Wildfires threaten tiger habitat, 1998. Drought and high winds fueled fires that destroyed 3.7 million acres (1,497,337 hectares) of taiga and threatened two important nature reserves that are habitat for the only remaining Amur tigers.
103. Bangladesh - Link between stronger El Ni�o events and cholera prevalence. Researchers found a robust relationship between progressively stronger El Ni�o events and cholera prevalence, spanning a 70-year period from 1893-1940 and 1980-2001. There has been a marked intensification of the El Ni�o/Southern Oscillation phenomenon since the 1980s, which is not fully explained by the known shifts in the Pacific basin temperature regime that began in the mid-1970s. Findings by Rodo et al. are consistent with model projections of El Ni�o intensification under global warming conditions. The authors make a strong case for the climate-health link by providing evidence for biological sensitivity to climate, meteorological evidence of climate change, and evidence of epidemiological change with global warming. The study likely represents the first piece of evidence that warming trends over the last century are affecting human disease.
105. Lake Baikal, Russia - Shorter freezing period. Winter freezing is about 11 days later and spring ice breakup is about 5 days earlier compared to a century ago. Some regions of Siberia have warmed by as much as 2.5�F (1.4�C) in just 25 years.
147. Iran - Desiccated wetlands, 2001 Ninety percent of wetlands have dried up after 2 years of extreme drought. Much of South West Asia has experienced a prolonged three-year drought that is unusual in its magnitude. Out of 102 years of record, 1999, 2000, and 2001 rank as the fifth, third, and seventh driest on record. 1999-2000 was the driest winter on record.
148. Pakistan - Longest drought on record, 1999-2001. The prolonged three-year drought, which covers much of South West Asia, has affected 2.2 million people and 16 million livestock in Pakistan.
149. Tajikistan - Lowest rainfall in 75 years, 2001. 2001 marked the third consecutive year of drought, which has destroyed half the wheat crop.
150. Korea - Worst drought in 100 years of record, 2001. It coincided with an average annual temperature increase in Asia�s temperate region, which includes Korea, by more than 1.8�F (1�C) over the past century. The warming has been most pronounced since 1970.
155. China - Disappearing Lakes, 2001. More than half of the 4,000 lakes in the Qinghai province are disappearing due to drought. The severity of the impact is exacerbated by overpumping of aquifers. Annual average temperature in China has increased during the past century, with pronounced warming since 1980. Most of the warming has been in northern areas, including Qinghai Province, and in the winter.

The Economic Valuation of Mangroves: A Manual for Researchers
by Camille Bann
Foreword
This manual on the Economic Valuation of Mangroves has been compiled and developed from a number of sources as an aid to researchers in Southeast Asia involved in the evaluation of mangrove ecosystems. A companion EEPSEA manual 'The Economic Valuation of Alternative Tropical Forest Land Use Options' (Bann, 1997) contains a more detailed theoretical discussion of the issues and valuation approaches presented here, and should be referred to by the user as appropriate.
The manual was originally developed as an aid to Cambodian researchers in the execution of an EEPSEA-Pioneered study of Koh Kong mangrove, Cambodia. (The report resulting from that study is available as an EEPSEA Research Report.)
Special thanks are due to Jack Ruitenbeek for careful comments on an earlier draft.
The main components of this Manual are: an introduction to the values of, and threats to, mangrove ecosystems (Chapter 1); a theoretical introduction to valuation of the environment (Chapter 2); a methodology for the economic assessment of mangrove management options (Chapters 3-9); a qualitative discussion of the possible impacts associated with common development options for mangrove ecosystems (Chapter 10); and, two case-study examples from Asia (Chapter 11).

Performance Evaluation of Commercial Bank
Performance Evaluation of Commercial Bank Branches Using Data Envelopment Analysis
Journal of Business and Management, 2005 by Yavas, Burhan F, Fisher, Dorothy M
Considerable research has been devoted to using multiple criteria to measure the performance of business units such as bank branches. However, bank managers continue to use traditional methods to evaluate their branch offices. In general, subjective weights for various criteria are used to arrive at a weighted average score to measure the performance of a bank branch. Potential deficiencies in an existing set of weights include bias and inconsistency with organizational objectives. This paper employs Data Envelopment Analysis (DEA) to evaluate the operational performance of a bank branch relative to the performance of its peer branches. Utilizing data from 31 branches of a major bank located in Southern California, the use of DEA yields the following: 1) rankings of bank branches using efficiency scores, 2) identification of areas of deficiency and 3) establishment of the reference group against which a branch is evaluated. Twenty-two of the 31 branches were found to be in need of improvements in various areas. In addition to identifying best-practice branches and those that are out-of-line with the best practice branches, DEA also points to the specific changes that must be made in the less productive branches in order for them to catch up with their best-practice peer group. The findings of this study should help management in identifying the strengths and weaknesses of their bank branches.
Discussion
Banks operate in a volatile environment that constantly requires them to alter their products and services. As indicated earlier, the trend is more revenues coming from such non-traditional offerings as insurance and financial services, while traditional banking revenues have declined. In fact, since World War II, the share of depository institutions in total assets held by the industry has declined from 55.9 percent to 35.6 percent between 1948 and 2000 (Saunders & Cornett, 2003). On the other hand, investment companies that give savers cheaper access to securities markets have seen their share of that business increase reflecting savers' shifting preferences toward securities markets over those products offered by commercial banks. In addition, information technology and a changing regulatory environment have resulted in consolidations in the commercial banking industry (Saunders & Cornett, 2003). In such an environment, banks compete with one another by developing new financial products and devising new ways of delivering these products to customers. Online banking and smart debit cards are two examples of new products in the banking industry. Equity and bond mutual funds are among the more recent offerings. Earlier examples of innovation included Automated Teller Machines (ATMs) and credit and debit cards.
Along with seriously considering and analyzing domestic trends, commercial banks must now also compete with foreign banks and other financial intermediaries. Against this background, it is clear that the future performance of commercial banks will be based largely on the extent to which they adopt the newest technologies and offer new, competitively priced products, such as mutual funds and insurance. In such a highly competitive environment, performance evaluation of bank branches assumes greater importance. The challenges brought about by this environment may require new operating principles that in turn make changes necessary at the bank branch level as the mix of product offerings changes. Regardless of the sources of these changes, bank managers must know whether their banking policies have improved productivity and whether the changes and the new initiatives affect some branches differently than others.
Instead of using traditional techniques such as ratio analysis and observation, the management of the bank studied here decided to use DEA to identify areas where improvement could be made in the performance of the branches while maintaining service quality and also pinpointing opportunities where savings could be achieved.
The identification of bank branches that are functioning efficiently in contrast to inefficient branches is one of the most important outcomes of a DEA assessment. This is so because both efficient and inefficient bank branches typically use a similar set of resources (inputs) in producing a similar mix of services (outputs) in a similar environment. Therefore, inefficient branches can learn from and emulate their efficient peers regarding what needs to be done to improve. Furthermore, operational practices identified as contributing to efficiency may be studied, and information gathered may be disseminated throughout the entire organization that seeks to investigate, improve and grow.
Suggestions for further use of DEA include development of a DEA-based index (Fare et al., 1994) that measures productivity change and can be used to investigate the changes in productivity resulting from changes in product offerings and/or operating principles. In addition to measuring the impact of new offerings, such analyses could help address the questions of how to allocate operating budgets to units, how to minimize financial risks at branch levels, and how to use inter-branch data to monitor a bank's performance vis-Ã -vis other branches as well as other banks in the industry.
