Many cities around the world are now rethinking of switching from the traditional kind of sidewalk to new types of cost-efficient and effective pedestrian pathways that will fit the times. Sidewalks can actually enhance walkability, generate renewable energy, and improve public safety, even as they withstand all those tree roots that have been breaking concrete slabs for decades. For this reason, sidewalks pose a challenge for planners on how to construct them and what kind of material to use without losing the idea of what a great sidewalk can be.
With global warming, the importance of trees multiplies a hundredfold, especially in cities and urbanized areas. They offer protection from calamities and diseases.
Urban street trees, specifically, provides benefits not just to the environment but to the people around them simply by existing in the middle and side of the roads, in parks, and around pocket communities.
