Participation paths

How researchers, practitioners and institutions take part in Cities and Built Environment, and what taking part does and does not mean.

01In brief

The short answer.

Taking part in Cities and Built Environment is open to urban researchers, city officials and planners and to institutions and national programmes working on cities and built environment. Experts contribute knowledge, review or data; institutions follow the GCRI participation routes; countries go through the Consortium Secretariat. An enquiry receives a reference and creates no membership, role or influence over findings.

From enquiry to contribution.

Participation paths: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

Urban signals in India.

For participation paths, in GCRI's spatial-intelligence reading, the map opens on night lights, population density and true-colour imagery with true colour from NASA GIBS, framed on India; 3 further NASA layers wait in the list.

The interactive map needs JavaScript; the layer list and sources are below.

05Contributions that help

What specialists can contribute to urban work.

Municipal datasets, community mapping done with consent and review of urban heat indicators are the main contributions; informal settlement data are accepted only with the safeguards agreed with residents.

  • Municipal data.
  • Community mapping with consent.
  • Review of heat indicators.
06What it means

Participation and its limits.

  • An enquiry receives a reference; it does not create membership, a role or an assignment.
  • Taking part gives no authority, appointment or influence over findings.
  • Conflicts of interest are declared before work begins.

The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.

07Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Declaration of interestsA written statement in which an expert or participant discloses financial, professional and personal interests that could constitute a real, potential or apparent conflict of interest, so that others can judge and manage it; WHO uses this procedure for its experts.
Service level R0The current service level of Nexus pages: information and enquiries only. An enquiry receives a reference and a named next step; it creates no membership, contract, assignment or commitment.
Community of practiceA group of people who share a concern or a craft and learn to do it better by interacting regularly; the term comes from Lave and Wenger's work on situated learning.
