Τα μεγάλα αστικά δέντρα αποτελούν φίλτρα για τους αστικούς ρύπους και τα λεπτά σωματίδια. Ένα δέντρο μπορεί να απορροφήσει έως και 150 κιλά CO 2 ετησίως, να δεσμεύσει τον άνθρακα και συνεπώς να αμβλύνει την κλιματική αλλαγή. Τα δέντρα παρέχουν ενδιαίτημα, τροφή και προστασία για τα φυτά και τα ζώα, αυξάνοντας την αστική βιοποικιλότητα. Φυτεύοντας δέντρα σήμερα είναι ουσιαστικής σημασίας για τις μελλοντικές γενιές!

The relationship between sustainable urban development and environmental sustainability is crucial to every strategy of urban transformation, renewal and regeneration. In particular, urban regeneration entails programmes of urban transformation that involve the rehabilitation of existing parts of a city, re-use previously built-up area and abandoned buildings, and redevelop blighted urban spaces to increase urban sustainability.

Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010).

This study is the first to assess land subsidence in the Kathmandu Valley, Nepal. Land subsidence simulations were based on a fully calibrated groundwater (GW) flow model developed using a coupled surface–subsurface modelling system. Subsidence is predicted to occur as a result of deep aquifer compaction due to excessive GW abstraction. The north and north-east areas at the periphery of the GW basin are hotspots for this subsidence. The estimated subsidence is most sensitive to changes in land cover within the recharge areas.

This research study explores urban planning for transport sustainability in two cities Kaunas (Lithuania) and Jelgava (Latvia). As part of the analyses, a transport sustainability was compared in relation to three main aspects – economy, environment and society. The aim of this research is to review the existing transport system in two cities – Kaunas and Jelgava, and to evaluate their sustainability in environmental, social and economic dimensions. The study is based on the information about configuration and location of the existing transport system in two cities – Kaunas and Jelgava.

The topic about shared real estate and ownership of landed property has become important only in the latest years. In connection with the rise of estate tax, the land’s cadastre value and the lease of land, the contradictions have also become more aggravated in shared real estate’s situations, which had occurred at some point when land reforms and privatization took place.
