Zalew Bardowskiego (Bardowski Lagoon) located in Targówek District of Warsaw. It is an artificial lagoon, constructed for purposes of recreation and water retention (so there is context of adaptation to climate change). Photos show the area both before, during and after construction.
In the last 20 years, the City of Warsaw has transformed into a vibrant city looking back not only on a rich cultural history but also on a set of climate actions aiming to improve environmental quality in the city. on 4 July 2019, the City of Warsaw finalized and approved its THE CLIMATE CHANGE ADAPTATION STRATEGY FOR THE CITY OF WARSAW BY 2030 WITH THE PROSPECTS UNTIL 2050. The strategy had been developed in a participatory process involving the citizens of Warsaw. With climate modelling techniques the city representatives co-authoring the strategy had defined the pre-condition of an expected average annual temperature increase of about 0.5°C every year for 25 years (resulting in an expected 10 to 12°C increase by 2100). In this sense, Warsaw’s Adaptation Strategy comprises adaptive measures designed to reduce the negative impact of hot weather periods, the urban heat island effect and preventing an increase of heat related mortality rates and damage caused by strong winds. In order to protect the city’s nature system from the consequences of drought and local flooding, Warsaw is also aiming to opt for different nature-based solutions (NBS) on its territory.
In July 2019, heavy rainfall caused, periods of draughts so it is important to catch the rainwater. The sewage system combines (rain and sewage).
One of the main needs is to purify water from rain so it can be used later.
Warsaw had identified main solutions for adaptation. These include, among others: green walls and roofs, monitoring and controlling urban heat island, rainwater retention, making buildings more resilient to climate change and weather disasters, or improvement of anti-flood infrastructure.
