Operating Organization Ben-Gurion University & Hebrew University

 

General Site Description:

The site established in 1958. We can still find in the site the remains of terraces from the Nabatean agriculture runoff. The main research topics that being studied in the site are: biodiversity, climate change, runoff hydrology

Purpose of Site:

The purpose of the site is to study the effect of rainfall and runoff patterns on ecological dynamics that includes population and community properties and ecosystem and landscape processes. In addition, the site provides ecosystem management knowledge with emphasis on runoff harvesting for agricultural purposes.

 

History of site:

The site was established in order to understand ancient agriculture (3000 years ago in a very arid environment) in order to understand the ancient agriculture, the studies were focus on rainfall-runoff- soil moisture- vegetation relationship. After the initial stage research was expanded to include plant physiology, population and community dynamic of plants, the effect of micro climate on animal behaver, decomposition processes, below and above ground relationships and the role of organisms as ecosystem engineers. Currently the site is adopting earth observation methods to understand land use, land cover processes and their effect on the ecosystem

 

Monitored parameters:

Meteorological data, rainfall and runoff, biomass, species richness, soil biota diversity, decomposition processes
