Evaluating Groundwater Management Sustainability under Limited Data Availability in Semiarid Zones

Improving Almond Productivity under Deficit Irrigation in Semiarid Zones

Sustainable water use is one of the greatest challenges of irrigated agricultural systems. This study presents the results related to the agronomic and physiological response to the deficit irrigation of almond trees (Prunus dulcis DA Webb Mill cv. Guara) under semiarid Mediterranean conditions in the Guadalquivir river basin (SW Spain). Two deficitirrigation strategies were tested: i) regulate...

Groundwater data management system

We have developed a system to manage groundwater data (geology, hydrology and geochemistry). The system is flexible, readily extensible and adaptable. It can load data in different formats. Loading and cleaning the data is performed by an ETL tool Pentaho Data Integration (aka. Kettle). The coordinates are converted by GeoKettle (spatial fork of Kettle). The database PostgreSQL uses our own dat...

Soil Respiration in Semiarid Temperate Grasslands under Various Land Management

Soil respiration, a major component of the global carbon cycle, is significantly influenced by land management practices. Grasslands are potentially a major sink for carbon, but can also be a source. Here, we investigated the potential effect of land management (grazing, clipping, and ungrazed enclosures) on soil respiration in the semiarid grassland of northern China. Our results showed the me...

Karst groundwater management by defining protection zones based on regional geological structures and groundwater flow fields

Karst regions, occupy approximately 25% of the land surface of the earth. Karst aquifers are often major sources of water supply in these areas. However, karst aquifers are generally considered to be particularly vulnerable to pollution and anthropogenic impacts. Large withdrawals of water in karst areas for municipal, agricultural, and industrial use may competitively affect water supply in su...
