With the Mongolian government implementation of integrated water resources management approach, assessing environmental flow requirements of major rivers becomes a primary issue. Using Indicators of Hydrological Alteration tools, physical habitat survey at Orkhon-Orkhon gauge site and statistical analysis of annual maximum flows, environmental low flow scenarios have been developed that attempt to reflect more "natural" characteristics of magnitude, frequency and duration. Specifically, minimum seasonal low flows of greater than the 75th percentile flow duration with bankfull flow releases during wet periods that have a duration of 12 to 24 days.

This report describes the results of a household survey conducted in September 2009 in a selected peri-urban subdistrict (bag) in Darkhan city. A total number of 139 randomly selected households were surveyed about the current status of environmental sanitation, including water supply, sanitation, stormwater management and solid waste management. Special focus was placed on socio-economic issues, the environmental sanitation practices and perceptions of the ger residents, and their attitudes towards and demand for improved environmental sanitation services. The results of the household survey are embedded in further research work assessing the water and sanitation sector in Darkhan city, Darkhan-Uul aimag and Mongolia, specifically in regard to peri-urban ger areas. The results reveal a problematic situation: Due to improved access to safe drinking water, water consumption and the corresponding wastewater have increased, leading to environmental degradation and potential health risks. Greywater is discharged untreated into greywater holes, open drainage channels or on open fields. Self-built unsealed pit latrines without cleanouts are used on every household's compound. Thus urine and faeces leak into the ground. Stormwater is collected in a perfunctory manner which can lead to stormwater flooding in the rainy season. Most of the interviewees were quite aware of these problems and were willing to contribute towards improvements. From the point of view of the ger residents, sanitation is the most pressing issue they face, followed by water supply, solid waste management and stormwater management. -- Mongolia ; environmental sanitation ; peri-urban ; ger areas ; household survey ; current status ; practices ; perceptions

Includes bibliographical references. ; Presented at the Building resilience of Mongolian rangelands: a trans-disciplinary research conference held on June 9-10, 2015 in Ulaanbaatar, Mongolia. ; In Mongolia, partners from national and aimag governments, academia and NGOs have developed regional conservation plans that balance the government commitment to protection of natural habitats with planned development of mineral resources and related infrastructure. A key input is a mapped classification of major habitat types, or ecosystems, to represent the range of natural habitats and function as a surrogate for biodiversity. We developed a GIS model to map ecosystems across the Mongolian Gobi Desert region by comparing the distribution of plant communities and major vegetation types, taken from field surveys and national maps, with patterns of above-ground biomass, elevation, climate and topography derived from remote sensing. The resulting mapped classification is organized as a hierarchy of 1) biogeographic regions, 2) terrestrial ecosystem types based on vegetation, elevation and geomorphology, and 3) landforms. This provides a first-iteration map to support landscape-level conservation planning and a model framework that can support field surveys and future model revisions, with other applications to land use planning, research, surveys and monitoring. To facilitate that, the GIS results are publicly available either for download or to view and query in a web-based GIS available at: http://s3.amazonaws.com/DevByDesign-Web/MappingAppsVer2/Gobi/index.html

Includes bibliographical references. ; Presented at the Building resilience of Mongolian rangelands: a trans-disciplinary research conference held on June 9-10, 2015 in Ulaanbaatar, Mongolia. ; In 2014 the Mongolian parliament approved the Green Development Policy. Out of 21 aimags, Khovd, Arkhangai, Uvurkhangai, Khentii and Bulgan aimags set an objective of prioritizing green development on their local level. This paper is based on the project "Conducting environmental and social vulnerability research of soums in five aimags leading in green development and developing strategy recommendation" and it is written using Khovd aimag as a case study. Here, in Khovd aimag's 17 soums, we evaluated eight variables including drought-dzud index, vegetation index, preventable livestock loss, prepared hay and fodder, pasture use index, degree of desertification, land degradation and surface water loss, allowing us to make an integrated assessment of ecological vulnerability. According to our analysis, the Gobi desert steppe region was defined as most vulnerable among environmental zones, and out of a total of 17 soums Altai, Uyench, Zereg, Chandmani and Duut soums were defined as most vulnerable, followed by Must, Darvi, Munkhhairkhan, Mankhan and Myangad soums. There is a need to give top priority to the planning and implementation of green policy in these ecologically more vulnerable soums by increasing their "green" budget. This will allow them to develop their capacity to adapt to climate change, decrease their vulnerability, to conduct optimal management of pasture use and have targeted preparation of hay and fodder.

Most fundamentally tenure and changing tenure is capturing the value of the resource. The nature of the resource and changing relative scarcity are essential to induce or lead evolution of land tenure. Pasture resources have been held in open access and communal tenure for much of the long history on Mongolia Plateau because of the abundant resource with low population density. Historically pasture tenure in this region has been evolving from open and semi-open access to communal tenure (control) to more private ownership, although other forces like political system can only cause temporary departure from the general patterns. Presently the variety of tenure arrangements largely reflects the scarcity of the pastoral resources: Mongolia is still primarily adopting semi-open access with community governing although state is viewed as sole ownership, while Inner Mongolia is more directing privatization of at least the use rights.
