This book provides experiences from studies on agricultural water management under climate change as references for agriculture and irrigation planners, decision makers, researchers and students. Chapters 2 and 3 provide an overview of global assessment of climate change impacts and water requirement for future agriculture. Chapters 4-7 provide analyses of crop water requirements in four case studies in developing countries. Chapters 8 and 9 are studies of irrigation management under sea-level rise in Vietnam's Mekong Delta. Chapters 10-12 discuss examples of adaptation alternatives such as water-saving techniques and groundwater exploitation, and related policy settings. The last chapter links the dominant approach of uncertainty presented in the climate change discourse with policy discussions on climate adaptation strategies.

Purpose – The purpose of this paper is to examine risk factors associated with Western Australian secondary school students' involvement in violence-related behaviours.
Design/methodology/approach – This cross-sectional study examined data collected using an anonymous self-completion questionnaire from 542 school students aged 13-17 years. The questionnaire measured risk factors associated with being a perpetrator and/or victim of violence-related behaviours.
Findings – Gender was significantly associated with being a victim and perpetrator of violence-related behaviours. Males were significantly more likely than females to be a victim of threatening and physical violence at school, and to be a perpetrator of physical violence at school and in the community. Males were significantly more likely than females to watch violent media, with exposure to violent media associated with physically hurting someone at school. Students involved in greater acts of animal cruelty had increased odds of being involved in all forms of the violence measured.
Research limitations/implications – Limitations such as the cross-sectional nature of the study and the small sample size are noted, along with suggestions for future research.
Practical implications – Implications of the research for practitioners working with adolescents, with a particular focus on the school setting, are discussed.
Originality/value – Most previously published research on adolescent involvement in violence has been conducted outside Australia, and as such, may not be directly applicable to the experiences of young people in Western Australia.

School-based health services (SBHS) including pastoral care can play a pivotal role in addressing adolescent health and wellbeing; including their tobacco and other drug use. To maximise the benefits of these services, they need to be accessible, useful for, and acceptable to students. This formative, qualitative study involved 12 focus groups within nine lower socio-economic Western Australian Government secondary schools. The purpose was to identify student (n = 59) perceptions of the availability and usefulness of SBHS (and other identified caring staff) to reduce students' harm associated with tobacco and other drug use. The findings suggest students were aware of the SBHS available to them, but considered them less useful if staff were regularly unavailable; presented a 'don't care' attitude; held solely disciplinary roles; and were based in an area of the school unfamiliar to the student. Services were considered useful when staff members built rapport with students; took time to listen; followed-up with students and displayed a general concern for the student's wellbeing. Interestingly, students acknowledged trusting health teachers more than SBHS staff for tobacco information and support. These findings have important implications for school counsellors and other school health/pastoral care staff who want to increase the likelihood of students approaching and using school support services to reduce harm associated with tobacco and other harmful drug (OHD) use.
The aim of this study is to describe the self‐reported experiences of adolescents in population‐based samples when completing health‐related surveys on topics with varying potential for evoking distress. Survey data were collected in three school‐based studies of bullying behaviors (N = 1,771, 12–14 years), alcohol use (N = 823, 12, 15, and 17 years), and electronic image sharing (N = 274, 13 years). Between 5% and 15% of respondents reported being upset at survey completion, but at most 1.4% were entirely negative in their evaluation. Age was not associated with being upset, but younger adolescents were more likely to see benefit in participation. Although concurrent mental health symptoms increased the risk of being upset, this was mostly mitigated by perceived benefits from participation.
Wetlands are too often perceived as standalone elements and are poorly integrated into river basin management. The Ramsar Convention recognizes the critical linkage between wetlands, water and river basin management; the governments that are party to the Convention have committed to conserving their wetlands within a framework of Integrated Water Resources Management (IWRM). The "Critical Path? approach and related guidance have been adopted by Contracting Parties of the Ramsar Convention in order to effectively integrate wetland conservation and management into river basin management planning and decision-making. However, despite international acceptance of the approach, it is not widely implemented. This paper provides one of the first case study based assessments of the Critical Path approach. The analysis of two contrasting Ramsar sites is presented in order to better understand the barriers to implementation in different development contexts. These are the Lobau wetland in Austria, where management institutions and regulatory frameworks are highly developed; and the Inner Niger Delta in Mali, where the capacity to implement IWRM is less evolved. A planning approach is proposed which involves structured and transparent methods for assessing ecosystem services and institutional capacity, and is suitable as a tool for identifying, prioritizing and negotiating trade-offs in ecosystem services and improving livelihoods. Based on the analysis, two main barriers to implementation are identified; mismatch between local and national or basin level priorities, and a lack of recognition of the ecosystem services provided by wetlands.
This special issue of Environmental Science and Policy presents the outcomes of the WETwin project (enhancing the role of wetlands in integrated water resources management for twinned river basins in EU, Africa and South-America in support of EU Water Initiatives), an international research project funded by the FP7 programme of the European Commission. The project aimed to improve wetland management by maximising benefits from wetland use while maintaining ecological health, using case studies from Europe, Africa and South America. In much of the less developed world, data on wetland functions, processes and values are scarce even while wetlands often provide a critical component of livelihoods. Management decisions on balancing competing demands for wetland use must often be made in the absence of comprehensive information. This paper introduces the approach developed and tested under WETwin to evaluate wetland management structures and solutions in datapoor contexts, summarising a conceptual framework which has evolved from seven very diverse case studies. A structured, modular approach was devised which combined multi-criteria analysis, trade-off analysis and vulnerability analysis, drawing on best available information, including quantitative modelling, qualitative ''expert opinion'', and local stakeholders' knowledge and values. The approach used in WETwin has three important strengths: it involves stakeholders at all stages of the decision process, it combines qualitative and quantitative data (and therefore allows inclusion of poorly known and potentially important system components) and finally, it provides a relatively simple and structured approach to evaluate wetland management interventions and integrate impact, feasibility and institutional assessments, vulnerability analysis and trade-off analysis. The overall conceptual framework developed for WETwin was found to be robust and transfer-able to different contexts.
In Ethiopia, exclosures in landscapes have become increasingly important to improving ecosystem services and reversing biodiversity losses. The present study was conducted in Gomit watershed, northern Ethiopia, to: (i) investigate the changes in vegetation composition, diversity and aboveground biomass and carbon following the establishment of exclosures; and (ii) analyse the economic returns of aboveground carbon sequestration and assess the perception of local communities on land degradation and exclosures. A space-for-time substitution approach was used to detect the changes in aboveground carbon, species composition, and diversity. Exclosures of 1-, 2-, 3-, 4-, 5-, and 7-years-old and a communal grazing land were selected. Household surveys, key informant interviews, and a financial analysis were used to assess the perception of local communities and the value of exclosure impacts, respectively. Significant (P = 0.049) differences in species diversity and considerable increases in aboveground carbon (ranged from 0.6 to 4.2 t C ha-1), CO2 storage (varied between 2.1 and 15.3 t CO2 ha-1), woody species composition, and richness (ranged from five to 28) were observed following the establishment of exclosures. Exclosures generated temporary certified emission reductions (tCER) of 3.4, 2.1, 7.5, 12.6, 12.5, and 15.3 Mg CO2 ha-1 after 1, 2, 3, 4, 5, and 7 years, respectively. The net present value (NPV) of the aboveground carbon sequestered in exclosures ranged from US$6.6 to US$37.0 per hectare and increased with exclosure duration. At a watershed level, 51.4 Mg C ha-1 can be sequestered, which represents 188.6 Mg CO2 ha-1, resulting in tCER of 139.4 Mg CO2 ha-1 and NPV of US$478.3 per hectare. This result would suggest that exclosures can potentially improve local communities' livelihoods beyond rehabilitating degraded lands if carbon stored in exclosures is traded. Communities in the watershed demonstrated that exclosures are effective in restoring degraded lands and they are benefiting from increased fodder production and reduced impacts of soil erosion. However, the respondents are also concerned over the sustainability of exclosure land management, as further expansion of exclosures aggravates degradation of remaining communal grazing lands and causes fuel wood shortages. This suggests that the sustainability of exclosure land management can be attained only if these critical concerns are addressed by a joint effort among government agencies, nongovernmental organizations, and communities.
The impacts of climate change on agriculture and food production in Southeast Asia will be largely mediated through water, but climate is only one driver of change. Water resources in the region will be shaped by a complex mixture of social, economic and environmental factors. This report reviews the current status and trends in water management in the Greater Mekong Subregion; assesses likely impacts of climate change on water resources to 2050; examines water management strategies in the context of climate and other changes; and identifies priority actions for governments and communities to improve resilience of the water sector and safeguard food production.
