Sustainability at HERDADE DOS LAGOS


The 1000 ha of Herdade dos Lagos are managed entirely organic. We waive all herbicides and only use plant protection products approved for organic farming.
We use the optimal conditions that we find in the Alentejo, with its large, untouched land and conserve natural resources. This results in natural wines and products that enable undisturbed taste.


The Alentejo is one of the regions in Europe with the most hours of sunshine per year. Therefore it seemed reasonable to use solar installations where solar energy can be used very efficiently.
In 2012, three large solar systems were connected with 43 KW at the Herdade dos Lagos.
We produce more energy than we take ourselves for irrigation and cooling and electricity can be fed into the public grid.


The south of Alentejo where the Herdade dos Lagos is located, has annual rainfalls of 200-600mm (compared to 984mm in the region around Bordeaux). In the summer months temperatures around 40°C occur regularly which results in complete dryness in many regions of the Alentejo. The otherwise unused expiring winter rain water is now collected in five reservoirs that have been built in recent years. It is used for irrigation of olives and wine in the dry season.
The water surfaces form rich habitats in the otherwise completely dried region.


Each year up to 1500 cranes and other migratory birds gather at the lakes of Herdade dos Lagos for their winter quarters.
The rainwater reservoirs provide refuge for several species of birds and plants; furthermore the sustainable cultivation of forest and fruit crops such as native Mediterranean holm oak, carob, olives, almonds, grapes and eucalyptus brings life and work in the otherwise deserted landscape. This forms the basis that different bird- and nature protection zones overlap in the area of ​​Herdade dos Lagos, particularly the NATURA 2000 zone of the EU. Its purpose is the transnational conservation of threatened wild native plant and animal species and their natural habitats.
