Gasa District or Gasa Dzongkhag (Dzongkha: མགར་ས་རྫོང་ཁག་; Wylie: Mgar-sa rdzong-khag) is one of the 20 dzongkhags (districts) comprising Bhutan. The capital of Gasa District is Gasa Dzong near Gasa. It is located in the far north of the county and spans the Middle and High regions of the Tibetan Himalayas. The dominant language of the district is Dzongkha, which is the national language. Related languages, Layakha and Lunanakha, are spoken by semi-nomadic communities in the north of the district. The People's Republic of China claims the northern part of Gasa District.
Gasa has an area of 3117.74km2,formerly 4409.3km2 .[2] It had a population of 3,116 as of the 2005 census, making it the largest, least populated, and thus least densely populated of all the dzongkhags; it is also the least developed district of Bhutan.
Gasa was formerly a drungkhag (sub-district) of the Punakha dzongkhag (district). It became a separate dzongkhag in 1992, the start of 7th Five Year Plan.
Gasa District is divided into four village blocks (or gewogs):[3] [4]
Gasa is bordered to the north by Tibet Autonomous Region of the People's Republic of China and by Thimphu, Punakha, and Wangdue Phodrang dzongkhags to the south.
Gasa has become a tourist destination because of its pristine forests and the exceptionally scenic location of its Dzong. In 2008 a massive flood on the Mo Chhu (Female River) destroyed a popular hot spring complex, which is under restoration and was to re-open in late 2011. The high altitude makes farming difficult, although government programs seek to establish mustard and summer vegetable planting programs. Residents herd yaks and dzos, and a small number benefit from the nascent tourism industry. A narrow road from Punakha, which is mostly unpaved, reaches up to the Dzong and is now being extended up to Laya. The majority of the known herds of wild Takin occur in Gasa. Electricity is also being supplied to some of the gewogs and all electrification programs are expected to be completed by 2012.
Gasa is most famous for its Layap people, and for the Snowman Trek, one of the most challenging treks in the Himalayas.
All of Gasa is an environmentally protected area of Bhutan. Most parts of the dzongkhag lie within Jigme Dorji National Park (Khamaed, Khatoed, Laya, Lunana Gewogs), although the northeast reaches of Gasa are part of Wangchuck Centennial Park (Lunana Gewog).[5] [6] Several of Bhutan's glaciers are located in Gasa, namely in Lunana Gewog, which borders Tibet.
