Dunglagang Gewog is one of the twelve Gewogs of Tsirang Dzongkhag. It is bordered by Kilkhorthang Gewog to the west, Sarpang Dzongkhag to the east, Semjong Gewog to the south, and Patshaling Gewog to the north. The Gewog covers an area of approximately 45.9 sq. km, with an altitude ranging from 900 to 1500 meters above the sea level. The Gewog is characterized by 90% forest coverage, comprising mainly cool and warm broad-leaved forests. Its topography includes high ridges, steep slopes, deep gorges, and lowland areas.

Dunglagang experiences a moderate climate, with hot summers and cool winters in the lower altitudes, and warm summers and cold winters in the higher regions. It receives an average annual rainfall of 850 mm to 980 mm. The Gewog consists of 365 households with a total population of 3,180, comprising 1,649 males and 1,531 females. The Gewog office is located under Kherithang Chiwog, approximately 14 km from the Dzongkhag headquarters. The Gewog Centre is connected by a 10.47 km blacktopped Gewog Centre Road, which was paved in 2018 and stretches from the Kilkhorthang junction. However, only 6 km of the road, from Kabreydara onwards, falls under the jurisdiction of Dunglagang Gewog, while the remaining stretch is under Kilkhorthang Gewog. Dunglagang Gewog comprises five Chiwogs: Kherithang, Lhamoilum, Dangreybu Maed, Dangreybu Toed, and Norjangsa.

All villages in every Chiwog are connected by 34 farm roads, totaling 78.35 km in length. The Gewog has 100% Rural Water Supply Scheme (RWSS) coverage, and all villages are covered by both T-Cell and B-Mobile networks. However, a few households in Norjangsa and Lhamoilum Chiwogs, located in shadow areas, have only partial network access,

either through B-Mobile or T-Cell.

Cardamom is the Gewog’s main agricultural product, followed by vegetables and oranges. Recently, farmers have also started cultivating kiwi, avocado, and other high-value fruits. Cereal crops such as paddy, maize, millet, quinoa, and wheat are also grown, albeit on a limited scale. Additionally, there is a growing interest in livestock farming, especially piggery, dairy, poultry, and goat farming. Among livestock products, pork is the most dominant, followed by dairy, poultry, and goat products.

The Gewog has one primary school, located at Lhamoilum Chiwog, and two ECCD centers, one each in Lhamoilum and Kherithang. It also has one Primary Health Centre (PHC) located at Kherithang, and an Outreach Clinic (ORC) at Norjangsa, with two health workers providing basic health services to the community. In terms of cultural sites, the Gewog is home to the Choekor Gatshel Lhakhang, located at mid- Lhamoilum, and a Hindu temple at Kherithang.

The Changchay River flows from Hatidunga village under Norjangsa Chiwog. Several tributary streams join it along its journey, including Tendovani, Uttary, and Kali from Norjangsa; Gopini,Noonpani, and Bararey from Lhamoilum Chiwog; Khorseney stream from Kherithang Chiwog; and Bitch stream from Dangreybu Maed and Dangreybu Toed. The river then flows downward through Goserling Gewog and eventually merges with the Sunkosh River.
