A synthesis of past, current and future research for protection and management of papyrus (Cyperus papyrus L.) wetlands in Africa
Papyrus wetlands (dominated by the giant
sedge Cyperus papyrus L.) occur throughout eastern,
central and southern Africa and are important for
biodiversity, for water quality and quantity regulation
and for the livelihoods of millions of people. To draw
attention to the importance of papyrus wetlands, a
special session entitled ââThe ecology of livelihoods in
papyrus wetlandsââ was organized at the 9th INTECOL
Wetlands Conference in Orlando, Florida in June
2012. Papers from the session, combined with additional
contributions, were collected in a special issue
of Wetlands Ecology and Management. The current
paper reviews ecological and hydrological characteristics
of papyrus wetlands, summarizes their ecosystem
services and sustainable use, provides an
overview of papyrus research to date, and looks at
policy development for papyrus wetlands. Based on
this review, the paper provides a synthesis of research
and policy priorities for papyrus wetlands and introduces
the contributions in the special issue. Main
conclusions are that (1) there is a need for better
estimates of the area covered by papyrus wetlands.
Limited evidence suggests that the loss of papyrus
wetlands is rapid in some areas; (2) there is a need for a
better understanding and modelling of the regulating
services of papyrus wetlands to support trade-off
analysis and improve economic valuation; (3) research
on papyrus wetlands should include assessment of all
ecosystem services (provisioning, regulating, habitat,
cultural) so that trade-offs can be determined as the
basis for sustainable management strategies (âwise
useâ); (4) more research on the governance, institutional
and socio-economic aspects of papyrus wetlands
is needed to assist African governments in
dealing with the challenges of conserving wetlands in
the face of growing food security needs and climate
change. The papers in the special issue address a
number of these issues

Decisional Conflict Scale Use over 20 Years: The Anniversary Review
Background. The Decisional Conflict Scale (DCS) measures 5 dimensions of decision making (feeling: uncertain, uninformed, unclear about values, unsupported; ineffective decision making). We examined the use of the DCS over its initial 20 years (1995 to 2015). Methods. We conducted a scoping review with backward citation search in Google Analytics/Web of Science/PubMed, followed by keyword searches in Cochrane Library, PubMed, Ovid MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, PRO-Quest, and Web of Science. Eligible studies were published between 1995 and March 2015, used an original experimental/observational research design, concerned a health-related decision, and provided DCS data (total/subscales). Author dyads independently screened titles, abstracts, full texts, and extracted data. We performed narrative data synthesis. Results. We included 394 articles. DCS use appeared to increase over time. Three hundred nine studies (76%) used the original DCS, and 29 (7%) used subscales only. Most studies used the DCS to evaluate the impact of decision support interventions (n = 238, 59%). The DCS was translated into 13 languages. Most decisions were made by people for themselves (n = 353, 87%), about treatment (n = 225, 55%), or testing (n = 91, 23%). The most common decision contexts were oncology (n = 113, 28%) and primary care (n = 82, 20%). Conclusions. This is the first study to descriptively synthesize characteristics of DCS data. Use of the DCS as an outcome measure for health decision interventions has increased over its 20-year existence, demonstrating its relevance as a decision-making evaluation measure. Most studies failed to report when decisional conflict was measured during the decision-making process, making scores difficult to interpret. Findings from this study will be used to update the DCS user manual
