What does it mean to be urban? Urban is defined as "that which is characteristic of a city." But what exactly is a city? In the past, walls may have defined a city. But today's city boundaries. They need to provide habitat for breeding, shelter, and food. Where possible, the habitat needs to be arranged in corridors where wildlife can safely travel. Though it may be too soon to call it an urban wildlife movement, initiatives focused on urban biodiversity seem to be catching on.

Abstract. Land take is the transformation of agricultural, natural, and semi-natural spaces into urban and other artificial uses. It is closely linked to urban sprawl (low-density or dispersed urban development). Land take is a major environmental challenge, especially for biodiversity conservation, as it destroys and fragments natural habitats. Roots has three golden rules for its 1,000-plus members. First, no dig — you have to replenish the soil. Then, no chemicals, including synthetic fertilisers and all the usual "-cides. A newly published study led by Yale School of the Environment researchers found that a projected urban expansion of up to 1.53 million square kilometers over the next three decades threatens the survival of more than 800 species — but also that a focus on urban planning that protects habitats can mitigate the impact. Urbanization has been a major driver of habitat loss over recent decades, but this trend can be shifted with better planning for sustainable urban growth and use of natural solutions, careful management of protected areas near cities, and integration of habitat into cities, the report finds.

Urban areas across the globe are facing the dual crises of COVID-19 and climate change, said the UN chief. Around 4.5 billion people live in cities today, but that population is projected to grow. According to UN Habitat, cities consume 78% of the world's energy and produce more than 60% of greenhouse gas emissions (UN Habitat, 2022).In the field of energy and the environment, reducing. Urban gardens boost biodiversity, make cities more sustainable. In building cities, we have created some of the harshest habitats on Earth—and then chosen to live in them. Temperatures in cities. Accessibility model for urban green infrastructure in Zagreb have seen a growing number of studies analysing the distribution of green areas in different cities and highlighting dis-parities in accessibility between ethnic and socioeconomic groups (e.g., Lee and Hong 2013; Dony et al. 2015). 5 Figure 1) Examples of urban green (Google 2021)

Urban ecologists view these as a series of "filters" that make it difficult for many species to persist in cities, especially those with specific habitat requirements. Myla Aronson, an urban ecologist at Rutgers University, pointed out, for example, that so-called ericaceous plants such as blueberries and rhododendrons, which require acidic. UN Climate Change News, 5 October 2020 - World Habitat Day celebrated today is an opportunity to focus on the state of the world's towns and cities, which will be home to two-thirds of the global population by 2050, and the role of urban development in climate action.
How urban is the world? What we know about urban populations and why it matters Before looking in more detail at the differences in estimates of urban populations, we should first clarify what we do know: globally more people live in urbanized settings than not (disputes in these figures are all above the 50% urban mark); What is an urban habitat?

A study published in the journal Landscape and Urban Planning found that an increase in urban vegetation cover can lead to a temperature reduction of up to 6°C in cities during day time (Ossola et al., 2021). Biodiversity Education and Awareness: Urban biodiversity serves as a unique opportunity for education and fostering environmental awareness. Also, habitat suitability of urban green spaces can be improved by reducing predation pressure by feral cats (Loss et al., 2013). In this case, management can be focused on the control of cat populations, owner education, and restricting cats' outdoor access (Loss and Marra, 2017). Finally, modifying plant composition or structure in urban.
