2020 NASA Project Working Group Field Study

From August to October, the working group on a scientific project on the topic: "Interdependent Dynamics of Food, Energy, and Water in Kazakhstan and Mongolia (FEWKaZMG): Connecting LULCC to the Transitional SocioEcological Systems" prepared sensors measuring the movement of small cattle (MRS) by installing the program and recharging the batteries for the long term work ahead.

A field trip to install collars with GPS trackers was carried out by a research group of the research university on October 3, 2020, in the direction of the Almaty region, the village of Shengeldy.

The survey route was compiled on the basis of the closest coverage of pasture animal husbandry in this village. Field research began with some adjustments due to the quarantine ban on travel outside the city of Almaty and completed on time. Collars with GPS trackers were installed on 48 cattle (sheep) selected from different herds, Shengeldy village

As a result of the joint work of an employee of the chief zoo technician of the village of Shengeldy and research university scientists, animals were selected for further research. These trackers using satellite images as a model of the state of the study area will be used in the analysis of the spatial characteristics of habitats and animal migration to understand the efficiency of the use of pasture lands.

Compared to traditional approaches, the use of GPS trackers in conjunction with space imagery technology for research has the following advantages:
1. Fixation of the state of environmental factors controlling the development of the studied population of animals, ensuring the uniformity and simultaneity of characteristics over large areas of the pasture.
2. A more accurate and up-to-date basis for spatial extrapolation of field description data and local key studies to assess the use of rangelands.
3. Evaluation of the dynamics of the habitat of small cattle and local shepherds based on a series of images at different times.
4. The ability to control the state of the habitat of the studied cattle, without permanent stay in the area of expeditionary work.

For the purposes of the study, the combination of future coordinates with satellite imagery data will give us the opportunity to analyze the features of the daily, daily, and seasonal motor activity (movement intensity) of small cattle on grazing, and to highlight the dominant landscapes and plant communities that are “selected” by cattle with relatively free pasture types of pastures by research region.
