The region plays a vital role in providing ecosystem services and is the basis of the livelihoods of over million people. The water and other ecosystem services provided by the HKH forms lifeline for one third of humanity.

In the past few decades, human activities and global warming have contributed to environmental degradation in significant portion of the region. Decreasing glacier area, growth in glacial lake size, unprecedented rainfall, changes in land use and land cover, forest degradation, floods and glacial lake outburst floods GLOFs , landslides, and shortfalls in agricultural crop production are among the many problems brought on by such change.

These issues need timely monitoring and supervision if they are to lead to a better understanding of the state of the environment, and the scale of the damages that has already been done. Effective monitoring of the environment, and an improved understanding of the same requires valuable information and data that can be extracted through the application of geospatial technologies such as remote sensing RS and geographic information system GIS.

This paper provides an overview of such research conducted in the HKH region. It shows how change assessment has been undertaken in thematic areas such as glacier, glacial lake, land use, land cover, and disaster events like floods, landslides and droughts and how sets of data collected over specific intervals of time are being used to identify and monitor the condition of the environment from the past to the present, and in the long run.

Complete database sets and analyses pertaining to these areas are made available online to facilitate access to information. Data formulation and further research are necessary to reduce scientific uncertainty and understand the impacts induced by climate change in the HKH. Scientific analyse made during each individual study can be used by decision makers and planners in environmental protection planning and development.

Remote Sensing of the Glacial Environment Influenced by Climate Change

Optical scientists are making globe-spanning measurements of ice, water, gases and the biosphere to assess the health of our living planet. Nearly every day brings news about climate change and its impacts, from wildfires in Greenland to melting ice on Antarctica to Europeans sweating through record-high summer temperatures. Laser ranging excels in quantifying how solids—such as ice sheets—increase or decrease in elevation. Hyperspectral imaging gathers full spectral data from each pixel in an image, revealing patterns of healthy and diseased life forms in their habitats. And, thanks to advances in portability, laser spectroscopy can fill in some crucial gaps in our knowledge of the distribution of problematic atmospheric gases. Many technologies work both for day-to-day weather sensing for meteorological models, and for tracking and assessment of longer-term climate trends.

Population Data and Global Environmental Change

In , the Human Dimensions of Global Environmental Change Programme HDP of the International Social Science Council charged its Working Group 3 on Demographic Data to inventory demographic data currently available; evaluate their adequacy for global environmental change research; recommend improvements in currently available data; and consider additional types of demographic data that may be needed. The resulting report highlighted the need for different databases at different levels of spatial resolution as high as 1 square kilometer , the importance of developing time series data at the different resolutions, and the desirability of unrestricted distribution of these data sets for scientific purposes. The report specifically recommended efforts to make available an existing georeferenced population database developed by the U.

Remote Sensing of Environment

Global environmental change remains a constant theme that resonates worldwide. The dynamics of the Earth system fosters complex spatio-temporal variations that highlight the significance of, and the need to monitor the Earth as a unified whole. Accurate, timely, and reliable data are a precursor to analyze and study several aspects of the integrated Earth system.

Он очень долго планировал, как осуществит свою мечту, и выбрал Нуматаку со всей тщательностью. Нуматек - богатая фирма, наиболее вероятный победитель аукциона. Ни у кого не вызовет подозрений, если ключ попадет именно к. И что особенно удачно - эту компанию меньше всего можно было заподозрить в том, что она состоит в сговоре с американским правительством. Токуген Нуматака воплощал старую Японию, его девиз - Лучше смерть, чем бесчестье. Он ненавидел американцев.

 Каковы ваши рекомендации? - требовательно спросил Фонтейн.  - Что вы предлагаете. - Рекомендации? - выпалил Джабба.  - Вы ждете рекомендаций. Что ж, пожалуйста. Хватит путаться у нас под ногами, вот моя рекомендация.

Халохот сделал стремительный прыжок. Вот. На ступенях прямо перед Халохотом сверкнул какой-то металлический предмет. Он вылетел из-за поворота на уровне лодыжек подобно рапире фехтовальщика. Халохот попробовал отклониться влево, но не успел и со всей силы ударился об него голенью.

ФБР, Налоговое управление, Агентство по борьбе с наркотиками и другие правоохранительные агентства США - с помощью опытных штатных хакеров - сумели арестовать и предать суду гораздо больше преступников. Разумеется, когда пользователи компьютеров во всем мире обнаружили, что американское правительство имеет широкий доступ к их электронной почте, раздались возмущенные голоса. Даже те, кто использовал электронную почту лишь для развлечения, занервничали из-за вторжения в их частную жизнь. Корпоративные программисты во всем мире озаботились решением проблемы безопасности электронной почты. В конце концов оно было найдено - так родился доступный широкой публике способ кодирования.

Remote sensing-based observations prove to be critical for the monitoring and assessment of cryosphere in the Himalayan region, where routine data collection in mountainous regions is often hampered by highly inaccessible terrain and harsh climatic conditions.
