ABSTRACT As a result of climate change in recent past and unsustainable land management, drought became one the most impacting disasters and, with projected global warming, it is expected to progressively cause more damages by end 21st century. This study investigates changes occurrence, frequency, severity Europe next decades. A combined indicator based on predominance signal over normal/wet conditions has been used. The indicator, which combines standardized precipitation index (SPI,...
In the context of climate change characterized by rising temperature and more extreme precipitation regimes, drought is one most relevant natural disasters. This paper presents maps global frequency, duration, severity for periods 1951–1970, 1971–1990, 1991–2010, to give an overview respective hot spots. Drought frequency defined as number events occurred, duration months in conditions, sum integral area below zero each event. Because mainly driven rainfall deficits, we chose Standardized...
Higher evaporative demands and more frequent persistent dry spells associated with rising temperatures suggest that drought conditions could worsen in many regions of the world. In this study, we assess how may develop across globe for 1.5, 2, 3°C warming compared to preindustrial temperatures. Results show two thirds global population will experience a progressive increase warming. For drying areas, durations are projected rise at rapidly increasing rates warming, averaged globally from 2.0...
Abstract An extreme heat wave occurred in Russia the summer of 2010. It had serious impacts on humans and natural ecosystems, it was strongest recorded globally recent decades exceeded amplitude spatial extent previous hottest European 2003. Earlier studies have not succeeded comparing magnitude waves across continents time. This study introduces a new Heat Wave Magnitude Index that can be compared over space The index is based analysis daily maximum temperature order to classify worldwide...
This study has three spatial scales: global (0.5°), macro-regional, and country scale. The database of drought events specific entries for each macro-region country. We constructed a meteorological from 1951 to 2016, now hosted by the Global Drought Observatory European Commission's Joint Research Centre. Events were detected at macro-regional scale based on separate analysis Standardized Precipitation-Evapotranspiration Index (SPEI) Precipitation (SPI) different accumulation scales (from 3...
Europe, including European Russia, but excluding Greenland, the Canary Islands, Azores, and Madeira. Drought is a complex climate-related phenomenon that can affect different sectors causing economic, social, environmental impacts. We focus on meteorological hydrological droughts, defined as shortage of precipitation over several months we discuss biggest drought events in 1950–2012. To define such computed three indicators, Standardized Precipitation Index, Evapotranspiration Reconnaissance...
Abstract Two questions motivated this study: 1) Will meteorological droughts become more frequent and severe during the twenty-first century? 2) Given projected global temperature rise, to what extent does inclusion of (in addition precipitation) in drought indicators play a role future droughts? To answer, we analyzed changes frequency, severity, historically undocumented extreme over 1981–2100, using standardized precipitation index (SPI; including only) precipitation-evapotranspiration...
Abstract. This study proposes a drought indicator that combines the Standardized Precipitation Index (SPI), anomalies of soil moisture and fraction Absorbed Photosynthetically Active Radiation (fAPAR). Computed at European level, Combined Drought Indicator (CDI) gives synthetic synoptic overview situation using classification scheme. Derived from integration three individual indices, this scheme is composed warning levels: "watch" when relevant precipitation shortage observed, "warning"...
In the last decades drought has become one of natural disasters with most relevant impacts in Europe and this not only water scarce areas such as Mediterranean that are inclined to events. As a complex phenomenon, is characterized by many hydro-meteorological aspects, large variety possible definitions. This study focuses on meteorological drought, investigated using indicators include precipitation potential evapotranspiration (PET), i.e. Standardized Precipitation Index (SPI)...
Abstract The implementation of the United Nations Convention to Combat Desertification (UNCCD) needs agreed, scientifically sound and practical methodologies for monitoring assessing state trend land degradation as well performance management programmes. lack sufficient integrated assessment (M&A) has in past been identified a major constraint combating desertification. Implementing efficient M&A programmes, however, requires careful analysis information different stakeholders, clear...
Abstract. Drought is one of the most costly natural hazards in Europe. Due to its complexity, drought risk, meant as combination hazard and societal vulnerability, difficult define challenging detect predict, impacts are very diverse, covering breadth socioeconomic environmental systems. Pan-European maps risk could inform elaboration guidelines policies address documented severity impact across borders. This work tests capability commonly applied indices vulnerability factors predict annual...
The Carpathians are the longest mountain range in Europe and a geographic barrier between Central Europe, Eastern Balkans. To investigate climate of area, CARPATCLIM project members collected, quality-checked, homogenized, harmonized, interpolated daily data for 16 meteorological variables many derived indicators related to period 1961–2010. principal outcome is Climate Atlas Carpathian Region, hosted on dedicated website (www.carpatclim-eu.org) made high-resolution grids (0.1° × 0.1°) all...
Drought is a global problem that has far-reaching impacts, especially on vulnerable populations in developing regions. This paper highlights the need for Global Early Warning System (GDEWS), elements constitute its underlying framework (GDEWF), and recent progress made toward development. Many countries lack drought monitoring systems, as well capacity to respond via appropriate political, institutional, technological frameworks, these have inhibited development of integrated management...
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...
ABSTRACT During the last decades, effects of global warming have become apparent also in Europe, causing relevant impacts many sectors. Under projected future warming, such a tendency can be expected to persist until end this century and beyond. Identifying which climate‐related are likely increase, by how much, is an important element any effective strategy for managing climate risks. This study investigates whether energy demand cooling heating buildings increase or decrease under change....
Over the past decades, a continuous rise in global air temperatures resulted significant changes hydrological cycle. Regionally increased frequencies of extreme weather events and regional extent drylands new areas at risk desertification, complex process driven by socio-economic climate-related factors. Although desertification is not confined to drylands, they are most vulnerable land degradation processes. To investigate possible climate patterns over 60 years, we couple information...
Abstract. We propose a composite drought vulnerability indicator (DVI) that reflects different aspects of evaluated at Pan-African level for four components: the renewable natural capital, economic capacity, human and civic resources, infrastructure technology. The selection variables weights assumption society with institutional capacity coordination, as well mechanisms public participation, is less vulnerable to drought; furthermore, we consider agriculture only one many sectors affected...

The probabilities of the occurrence extreme dry/wet years and seasons in Europe are estimated by using two ways Standardized Precipitation Index (SPI SPI‐GEV) Nonstationary (SnsPI). latter is defined as SPI fitting precipitation data with a nonstationary Gamma distribution order to model time dependence under climate change. Bias‐corrected daily outputs from five different regional models (RCMs) provided ENSEMBLES project used. RCMs selected so represent main statistical properties whole set...
A correct identification of drought events over vegetated lands can be achieved by detecting those soil moisture conditions that are both unusually dry compared with the 'normal' state and causing severe water stress to vegetation. In this paper, we propose a novel index accounts for mutual occurrence these two means multiplicative approach deficit factor dryness probability factor. The former quantifies actual level plant stress, whereas latter verifies current condition is unusual specific...
