Complex changes in carbon sources and sinks caused by rapid urbanization have been observed with extensive changes in the quantity, structure, and spatial pattern of land use types. Based on the modified Carnegie-Ames-Stanford Approach model and on gray relational analysis, we analyzed the influence of land use changes on carbon sinks and emissions in Guangzhou from 2000 to 2012. The aim was to identify suitable options for built-up land expansion that would allow for minimal carbon losses.

Land use change is one of the main stress factors on ecosystems near urban areas. We analysed land use dynamics within Xochimilco, a World Heritage Site area in Mexico City. We used satellite images and GIS to quantify changes in land use/land cover (LULC) from 1989 to 2006 in this area, and a Markov projection model to simulate the impact of different management scenarios through to 2057. The results show an alarming rate of urbanisation in 17 years. LULC change runs in one direction from all other land use categories towards urban land use.

Despite the global trend in urbanization, little is known about patterns of biodiversity or provisioning of ecosystem services in urban areas. Bee communities and the pollination services they provide are important in cities, both for small-scale urban agriculture and native gardens. To better understand this important ecological issue, we examined bee communities, their response to novel floral resources, and their potential to provide pollination services in 25 neighborhoods across Chicago, IL (USA).

A social audit is a community-led process of reviewing of crucial documents to determine whether the public expenditure and service delivery outcomes reported by the government really reflect the public money spent and the services received by the community. Members of the community collectively participate in a process of verifying government (or private company) documents by comparing them with the realities on the ground and the experiences of the community. Evidence collected during the audit is then reported to the responsible authorities at a public meeting.

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.

On this day 9 April 2015, in Seoul, the capital of the Republic of Korea, on the occasion of the ICLEI World Congress 2015, ICLEI Members and representatives of local, subnational governments and our partners worldwide, proclaim the ICLEI Seoul Declaration.

A defining feature of many of the world’s cities is an outward expansion far beyond formal administrative boundaries, largely propelled by the use of the automobile, poor urban and regional planning and land speculation. A large proportion of cities both from developed and developing countries have high consuming suburban expansion patterns which often extend to even further peripheries. Cities need to accommodate new and thriving urban functions such as transportation routes, etc. as they expand.

Geoffrey Payne outlines five fundamental propositions that are key to his understanding of tenure issues and policy options.

These are:

1) That access to affordable land with adequate security of tenure and associated rights is a pre-condition for realising the goal of adequate housing and poverty reduction;

The Latin American and Caribbean Urban CSO Cluster, part of the Global Land Tools Network (GTLN), together with Habitat for Humanity’s Solid Ground Campaign and the Land Portal Foundation, launched an online debate on Urban Land Conflicts in Latin America and the Caribbean in January 2017. Responding to the common interest to make information easy to access and flow to boost collaboration among stakeholders as a critical basis to improve land governance.
