“…The EU-funded WETWIN project (2009-2011) incor-porated two papyrus wetlands (Namatala and Nabajuzzi) in Uganda and aimed at developing integrated approaches for management (Cools et al 2013;Johnston et al 2013). The Netherlands-funded ECOLIVE project (2009-2013) involved a transdisciplinary study of the Nyando wetland in Kenya, incorporating hydro-logical, ecological and socioeconomic sub-projects (van Dam et al 2011. In addition to studies of the natural wetland environment, there were also various studies on papyrus in constructed wetlands for water quality regulation (Chale 1985(Chale , 1987Okurut et al 1999;Okurut 2001;Kyambadde et al 2005;Abira et al 2005).…”

Van Dam, A.A. et al. (2014). A synthesis of past, current and future research for protection and management of papyrus (Cyperus papyrus L. 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 ('wise use'); (4) more research on the governance, institutional and socio-economic aspects of papyrus wet-lands 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.

“…Both are suited to assessing wetlands management when there are limited data, because they facilitate the direct involvement of stakeholders, cater for both deductive and inductive logic, and explicate stakeholder mental models with their probable, causal relationships, that form the basis for action by stakeholders (Fu et al, 2011;Kipkemboi, 2006;Maclean et al, 2011;van Dam et al, 2011;van Dam et al, 2013).

A study of the drivers of land use change in the Ha Tien Plain region of the Mekong Delta, Vietnam

The wetlands of the Mekong Delta (MD) have contributed prominently to economic development in Vietnam, especially to agricultural and fisheries development. Unfortunately, the design of wetland utilization has traditionally been considered from an economic rather than ecological perspective, and wetlands utilization has suffered from a lack of scientific guidance. Many wetlands have been lost because their full value to society was not taken into account. Furthermore, the status of the delta's biodiversity is both poorly known and poorly documented. Decades of over-exploitation of the wetland ecosystems have had detrimental effects on the environment. The maintenance of the important economic functions of the MD is dependent on maintaining the wetlands' ecosystem functions.This thesis addresses several gaps in the broader wetland conservation literature by focusing on the research problem "How can the drivers of land use change in the study area be better managed to lead to more sustainable outcomes?" Using Systems Thinking in combination with Bayesian Belief Networks modelling methods, and a case study of the Phu My Lepironia grassland biodiversity conservation in Kien Giang, Vietnam, this thesis examines how successful community-based wetlands conservation can be achieved in the Mekong Delta. The study is comprised of the following components: (1) a review of the history of the drivers of wetlands degradation in the MD in order to better understand the transformation of the delta's wetlands in different periods, and an analyses of the driving forces of wetland loss and the underlying causes that derive from the differing policies of political regimes; (2) a study of various factors that influence wetlands grassland degradation and the likely consequences of conservation of the wetlands for carbon stocks; and (3) an analysis of the factors affecting how local communities' decide to make changes in their land use practices, and policy interventions that lead to the enhancement of livelihoods and improved sustainability of wetland grassland conservation in the study area.The drivers that have contributed to wetland loss and degradation in the Mekong Delta over the course of 200 years can be divided into five periods. The drivers of wetland losses have included: (1) resettlement and economic development policies; (2) population growth and urbanization; (3) demand for food and reclamation of wetlands for agriculture, construction of canals and construction of dikes for flood protection systems; (4) expansion of travel systems (waterways and roads); and (5) exploitation of wetlands natural resources. As a result of these factors, only 0.068 million ha of the original 4.0 million ha of the MD currently remain as a primary swamp forest ecosystem.ii The analysis presented in this thesis estimates the value of CO2 sequestered by different Mekong Delta wetland ecosystems (mangroves, Melaleuca swamps and wetland grasslands) to be between 5.53 Mt CO2e for grasslands ecosystem to 37.49 Mt CO2e for mangrove ecosystem...

Quantifying resistance and resilience to local extinction for conservation prioritization

Species‐focused conservation planning is often based on reducing local extinction risk at key sites. However, with increasing levels of habitat fragmentation and pressures from climate change and overexploitation, surrounding landscapes also influence the persistence of species populations, and their effects are increasingly incorporated in conservation planning and management for both species and communities. Here, we present a framework based on metapopulation dynamics in fragmented landscapes, for quantifying the survival (resistance) and reestablishment of species populations following localized extinction events (resilience). We explore the application of this framework to guide the conservation of a group of threatened bird species endemic to papyrus (Cyperus papyrus) swamps in East and Central Africa. Using occupancy data for five species collected over two years from a network of wetlands in Uganda, we determine the local and landscape factors that influence local extinction and colonization, and map expected rates of population turnover across the network to draw inferences about the locations that contribute most to regional resistance and resilience for all species combined. Slight variation in the factors driving extinction and colonization between individual papyrus birds led to species‐specific differences in the spatial patterns of site‐level resistance and resilience. However, despite this, locations with the highest resistance and/or resilience overlapped for most species and reveal where resources could be invested for multispecies persistence. This novel simplified framework can aid decision making associated with conservation planning and prioritization for multiple species residing in overlapping, fragmented habitats; helping to identify key sites that warrant urgent conservation protection, with consideration of the need to adapt and respond to future change.
