Abstract
We assessed a donor-funded grassland management project designed to create both conservation and livelihood benefits in the rangelands of Mongolia's Gobi desert. The project ran from 1995 to 2006, and we used remote sensing Normalized Differential Vegetation Index data from 1982 to 2009 to compare project grazing sites to matched control sites before and after the project's implementation. We found that the productivity of project grazing sites was on average within 1% of control sites for the 20 years before the project but generated 11% more biomass on average than the control areas from 2000 to 2009. To better understand the benefits of the improved grasslands to local people, we conducted 280 household interviews, 8 focus group discussions, and 31 key informant interviews across 6 districts. We found a 12% greater median annual income as well as a range of other socioeconomic benefits for project households compared to control households in the same areas. Overall, the project generated measurable benefits to both nature and people. The key factors underlying project achievements that may be replicable by other conservation projects include the community-driven approach of the project, knowledge exchanges within and between communities inside and outside the country, a project-supported local community organizer in each district, and strong community leadership.Entities:

Analytical structure of the ecological assessment.
| Comparison | Imagery Source | Unit of Analysis | Scope |
| Before versus after project | AVHRR | By year, pre-conservation (1982-99) versus post-conservation (2000-06) | 6 of the 12 project districts |
| Treated versus control sites | MODIS | By year (2000-2009) | 39 treated and 37 control data points |
| Treated versus control sites | AVHRR | By year (2000-06) | 18 treated and 18 control data points |

Figure 3Ten-Year Seasonal Growth Curve Comparison (NDVI).
Shows how the 10-year average growth of the 39 community pastures compares with the average from the 37 non-community matched control sites (t-test = 2.715, df = 18, p = 0.014). The community pastures had a longer growing season and higher peak NDVI and produced more biomass than the non-community control pastures. *Above 0.1 is when plants can be grazed [26]. Error bars = one standard error.
Figure 4Seasonal Biomass Growth (TI-NDVI).
Shows how the 39 community pastures' seasonal growth in biomass compares to the 37 non-community controls (t-test = 2.103, df = 18, p = 0.05). Variation year-to-year is due to rainfall. Error bars = one standard error.
