Land is integral to securing shelter, agriculture for food security, mobilising investments and for the sustainable management of resources. With these issues in focus, Habitat for Humanity's Solid Ground Campaign, in association with the Urban CSO Cluster of the Global Land Tool Network (GLTN) of UN-HABITAT, will be hosting a conference in Pretoria, 15-17 August.
Cities function in an efficient, equitable and sustainable manner only when private and public spaces work in a symbiotic relation to enhance each other. Public space generates equality, however in the past decades it has been drastically been reduced. Inadequate, poorly designed, or privatized public spaces generate exclusion and marginalization.
In September 2015, the United Nations Sustainable Development Summit adopted a new framework to guide development efforts between 2015 and 2030, entitled “Transforming our world: the 2030 Agenda for sustainable development”.1
The New Urban Agenda represents a shared vision for a better and more sustainable future – one in which all people have equal rights and access to the benefits and opportunities that cities can offer, and in which the international community reconsiders the urban systems and physical form of our urban spaces to achieve this.
- There is an accute lack of well-located urban housing that is adequate, secure, and affordable. The global affordable housing gap is currently estimated at 330 million urban households and is forecast to grow by more than 30 percent to 440 million households, or 1.6. billion people, by 2025.
- This paper defines three key challenges to providing adequate, secure and affordable housing in the global south: the growth of informal or substandard settlements, the overemphasis on home ownership, and inappropriate policies or laws that push the poor out of the city.
This paper has been compiled by Ndifuna Ukwazi following extensive consultation with practitioners and experts in housing finance, architecture, social housing, city planning, urban design, and local and provincial government.
Today, more than half the world’s population lives in cities. By 2030, it is projected that 6 in 10 people will be urban dwellers. By 2050, the figure will have risen to 6.5 billion people; representing two-thirds of all civilization. Taking into account the increasing rural to urban migration and the rapid growth of cities in the developing world, it is clear that cities face a myriad of problems that may hinder planned growth and development.
Climate change and energy saving are challenging the city and the territorial organization. Innovative spatial and urban planning methods and procedures are required, and new approaches and instruments must be elaborated and applied in order to shift from the building scale to the urban and territorial ones.
Dhaka city in Bangladesh has been passing through a hasty process of urbanization and population growth since the last few decades. Rapid growth of population, unplanned urbanization and industrialization in the periphery has generated pressure to the changes in land use pattern, which has also caused huge urban expansion. This expansion process is engulfing cultivated land, vegetation, wetlands and water bodies without considering their environmental impacts.
Detailed, up-to-date information on intra-urban land cover is important for urban planning and management. Differentiation between permeable and impermeable land, for instance, provides data for surface run-off estimates and flood prevention, whereas identification of vegetated areas enables studies of urban micro-climates. In place of maps, high-resolution images, such as those from the satellites IKONOS II, Quickbird, Orbview and WorldView II, can be used after processing.
