a guideline, we typically recommend up to 50. * Analyses include received/accepted dates.  * Analyses may be accompanied by supplementary information.  * Analyses are peer reviewed.

_____________________________________________________________________________________________________________________________________ CORRESPONDENCE The Correspondence section provides a

forum for comment on issues relevant to the journal’s community. This format may not be used for presentation of research data or analysis.  Format * Correspondence – between 300-800 words.

* Display items – 1 item. * References – up to 10 references. Article titles are omitted from the reference list.  * Correspondence may be peer-reviewed at the editors’ discretion.  Note

that Correspondence pieces are not technical comments on peer-reviewed research papers; these should be submitted as Matters Arising.

______________________________________________________________________________________________________________________________________ REVIEW A Review is an authoritative, balanced and

scholarly survey of recent developments in a research field. Although Reviews should be recognized as scholarly by specialists in the field, they should be written with a view to informing

non-specialist readers. Reviews should therefore be written using simple prose, avoiding excessive jargon and technical detail.  The scope of a Review should be broad enough that it is not

dominated by the work of a single research institution, and particularly not by the authors' own work. Unpublished primary research data are not permitted in Reviews. Reviews include

received/accepted dates. Reviews are peer-reviewed to ensure factual accuracy, appropriate citations and scholarly balance; they are edited by the journal editors in consultation with the

authors. Reviews are usually commissioned by the editors, so it is advisable to send a pre-submission enquiry including a synopsis before preparing a manuscript for formal submission. Format

* Abstract – up to 150 words, unreferenced. * Main text – up to 6,000 words (excluding abstract, references, figure/table captions and boxes). * Display items – up to 8 (either figures,

tables or boxes). * References – up to 120. ______________________________________________________________________________________________________________________________________ PERSPECTIVE

A Perspective is a review of a topic from a personal viewpoint. They may be more forward-looking and/or speculative than Reviews and typically have a narrower scope. Despite being

opinionated, they should be balanced; they are intended to stimulate discussion and new approaches. Perspectives may not contain primary research data. Perspectives are approximately 4,000

words long and begin with a 100–150-word unreferenced abstract written for a general audience. Perspectives typically include 2–4 display items (figures, tables or boxes). As a guideline,

Perspectives allow up to 120 references; citations should be selective. Footnotes are not used. Perspectives include received/accepted dates. Perspectives are peer-reviewed to ensure factual

accuracy, appropriate citations and scholarly balance; they are edited in consultation with the editorial team. Format * Abstract – up to 150 words, unreferenced. * Main text – up to 4,000

words (excluding abstract, references, figure/table captions and boxes).  * Display items – up to 5 (either figures, tables or boxes) * References - up to 120.

______________________________________________________________________________________________________________________________________ COMMENT A Comment is a flexible format, focusing on the

scientific, commercial, ethical, legal, societal, or political issues surrounding research, or on other matters of policy, science and society related to water. Comment articles should be

topical, readable, provocative and introduce new concepts/points of view, providing a personal perspective on a matter of public or scientific importance. The main criteria are that they

should be of immediate interest to a broad readership and should be written in an accessible, non-technical style.  FORMAT * Length – up to 2,000 words. * There are no specific structural

guidelines. * Commentaries do not normally contain primary research data, although they may present 'sociological' data (funding trends, demographics, bibliographic data, etc.).  *

References should be used sparingly – up to 15. * Article titles are omitted from the reference list. * Peer review is at the editors' discretion.

______________________________________________________________________________________________________________________________________ MATTERS ARISING Matters Arising are exceptionally

interesting and timely scientific comments and clarifications on original research papers published in _Nature Water_. These comments should ideally be based on contemporary knowledge rather

than subsequent scientific developments. ______________________________________________________________________________________________________________________________________ NEWS &

VIEWS News & Views articles inform readers about the latest advances, as reported in recently published papers (in _Nature Water_ or elsewhere) or at scientific meetings.  Most News

& Views articles are commissioned, but proposals for papers or meetings to be covered in this section can be made to the editorial team. Suggestions must be received in advance of the

paper being published (or shortly thereafter) to ensure our coverage is as timely as possible. News & Views articles are not peer reviewed.

______________________________________________________________________________________________________________________________________ POLICY BRIEF Policy Briefs are arranged by invitation

only. They provide a summary of the policy implications of a paper published in Nature Water for a policy audience.

______________________________________________________________________________________________________________________________________ FEATURE A Feature encompasses both the technical and

commercial aspects of any topic relevant to our readership. This format is intended to complement the emerging scientific developments reported in the research section, and also to provide a

forum for regulatory and business topics that would otherwise not be covered in the journal.  _Nature Water_ welcomes ideas for topics and proposals can be sent by email. Format * Length – 

up to 3,000 words. * Use of tables and figures is strongly encouraged. * Written in a journalistic style, accessible to a wide range of non-specialist readers.
