Abstract Background . Coastal river deltas provide multiple ecosystem services. Many serve as major centers of agriculture, industry and commerce. The annual economic benefits derived from are often a substantial fraction country’s GDP. Yet, many losing land due to erosion, subsidence subsequent flooding. Such vulnerabilities increased local water management decisions, relative sea-level rise, increases in climate extremes. Aim this review Considerable literature exists addressing the formation effects increasing urbanization, industrialization crop fish production, sea level decreasing sediment deposition.

Abstract Reducing the social, environmental, and economic impacts of droughts identifying pathways towards drought resilient societies remains a global priority. A common understanding drivers risk ways in which materialize is crucial for improved assessments identification (spatial) planning targeted reduction adaptation options. Over past two decades, we have witnessed an increase across spatial temporal scales drawing on multitude conceptual foundations methodological approaches. Recognizing diversity approaches science practice as well associated opportunities challenges, present outcomes systematic literature review state art people-centered vulnerability conceptualization assessments, identify persisting gaps. Our analysis shows that, reviewed (i) more than 60% do not explicitly specify type hazard that addressed, (ii) 42% provide clear definition risk, (iii) 62% apply static, index-based approaches, (iv) 57% indicator-based their weighting methods, (v) only 11% conduct any form validation, (vi) ten percent develop future scenarios (vii) about 40% establish direct link to or strategies, i.e. consider solutions. We discuss challenges with these findings both assessment measures, research needs inform policy agendas order advance support societies.

Abstract. Droughts continue to affect ecosystems, communities and entire economies. Agriculture bears much of the impact, in many countries it is most heavily affected sector. Over past decades, efforts have been made assess drought risk at different spatial scales. Here, we present for first time an integrated assessment both irrigated rainfed agricultural systems global scale. Composite hazard indicators were calculated separately using indices based on historical climate conditions (1980–2016). Exposure was analyzed non-irrigated crops. Vulnerability assessed through a socioecological-system (SES) perspective, socioecological susceptibility lack coping-capacity that weighted by experts from around world. The analysis shows displays heterogeneous pattern level, with higher southeastern Europe as well northern southern Africa. By providing information drivers patterns all dimensions hazard, exposure vulnerability, presented can support identification tailored measures reduce increase resilience systems.

The regular drought episodes in South Africa highlight the need to reduce risk by both policy and local community actions. Environmental socioeconomic factors Africa's agricultural system have been affected past, creating cascading pressures on nation's agro-economic water supply systems. Therefore, understanding key drivers of all components through a comprehensive assessment must be undertaken order inform proactive management. This paper presents, for first time, national irrigated rainfed systems, that takes into account complex interaction between different components. We use modeling remote sensing approaches involve experts selecting vulnerability indicators providing information human natural drivers. Our results show municipalities last 30 years. years 1981-1982, 1992, 2016 2018 were marked as driest during study period (1981-2018) compared reference (1986-2015).

Due to increasing population pressure and urbanization, as well global climate change impacts, many coastal river deltas are experiencing increased exposure, vulnerability risks linked natural hazards. Mapping the risk profiles of is critical for developing preparedness, mitigation adaptation policies strategies. Current assessments focus predominantly on social factors, typically, do not systematically incorporate a social-ecological systems perspective, which can lead incomplete assessments. We argue that ecosystem services, link both functions human well-being, be used better characterize mutual dependencies between society environment within assessment frameworks. Thus, building existing frameworks, we propose revised indicator-based framework delta environments, supported by list service indicators were identified using systematic literature review. This improved an effective tool address in deltas, enabling multi-hazard across allows more targeted development management measures aimed at reducing from
