As aquaculture becomes more important for feeding the growing world population, so too do required natural resources needed to produce feed. While there is potential replace fish meal and oil with terrestrial feed ingredients, it understand both positive negative implications of such a development. The use large proportion may reduce pressure on fisheries provide fish, but at same time significantly increase freshwater resources, due water consumption pollution in crop production aquafeed....
Human activities both aggravate and alleviate streamflow drought. Here we show that aggravation is dominant in contrasting cases around the world analysed with a consistent methodology. Our 28 included different combinations of human-water interactions. We found water abstraction aggravated all drought characteristics, increases 20%–305% total time across case studies, deficit up to almost 3000%. Water transfers reduced by 97%. In into catchment or augmenting from groundwater, inputs could...
Drought impacts monitoring has been called the missing piece in drought assessment. The potential to improve management is high but uncertain due rare analyses of datasets, predominantly because there are few programmes generate datasets. conducted on ground much Brazil by local observers at monthly and municipality scale support Brazilian Monitor. In Ceará state, within drought-prone semiarid northeast Brazil, over 3600 reports were completed agricultural extension officers from 2019 2022....
This special issue is a collection of recent papers in the field Water Footprint Assessment (WFA), an emerging area research focused on analysis freshwater use, scarcity, and pollution relation to consumption, production, trade. As increasing scarcity forms major risk global economy, sustainable management water resources prerequisite development. We introduce this by relating them Sustainable Development Goal (SDG) number 6 United Nations, goal water. will particularly articulate how each...
Abstract. Drought events and their impacts vary spatially temporally due to diverse pedo-climatic hydrologic conditions, as well variations in exposure vulnerability, such demographics response actions. While hazard severity frequency of past drought have been studied detail, little is known about the effect management strategies on actual how perceived by relevant stakeholders. In a continental study, we characterised assessed perceptions two recent (2018 2019) Europe examined relationship...
Abstract. Drought monitoring and early warning systems (DEWSs) are seen as helpful tools to tackle drought at an stage reduce the possibility of harm or loss. They usually include indices attributed meteorological, agricultural and/or hydrological drought: physically based drivers. These used determine onset, end severity a event. impacts, like water food securities, less monitored even not included in DEWSs. Therefore, likelihood experiencing these impacts is often simply linearly linked...
Abstract Drought‐affected regions often contain high densities of small reservoirs, usually informally built, as drought‐coping mechanism. These structures influence socio‐hydrological dynamics and have the potential to alter hydrological processes relevant drought emergence development. This study aimed analyze a concentration reservoirs on intensification evolution events. We present an innovative method, which we call “Drought Cycle Analysis”, that tracks concomitance precipitation water...
Different methods have been proposed in population dynamics to estimate carrying capacity (K). This study estimates K for Iran, using three novel by integrating land and water limits into assessments based on Human Appropriated Net Primary Production (HANPP). The first method uses suitability as the limiting resource. It gives theoretical K. second which is method, resources availability assuming highly efficient agriculture, also resulting third a lower, more realistic agricultural...

Semi-arid river basins often rely on reservoirs for water supply. Small may impact large-scale availability both by enhancing in a distributed sense and subtracting large downstream user communities, e.g. served reservoirs. Both of these impacts small are subject to climate change. Using case-study North-East Brazil, this paper shows that change be severe, from exceed centralised Next, the effect significant, increase relative absolute under unfavourable
Location-specific forms of agroforestry management can reduce problems in the forest–water–people nexus, by balancing upstream and downstream interests, but social ecological finetuning is needed. New ways achieving shared understanding underlying social-ecological relations needed to adapt contextualize generic solutions. Addressing these challenges between thirteen cases tropical scenario development across three continents requires exploration aspects issues, knowledge participative...
To effectively manage hydrological drought, there is an urgent need to better understand and evaluate its human drivers. Using the "downstreamness" concept, we assess role of a reservoir network in emergence evolution droughts river basin Brazil. In our case study, downstreamness concept shows effect reservoirs on spatial distribution stored surface water volumes over time. We demonstrate that, as consequence meteorological drought recovery, became spatially skewed towards upstream...
Abstract Drought management is currently informed by a variety of approaches, mostly responding to drought crisis when it happens. Toward more effective and integrated management, we introduce conceptual diagnosis framework inspired diagnostic concepts from the field medicine. This comprises five steps: 1. Initial assessment; 2. Diagnostic testing; 3. Consultation; 4. Communication diagnosis; 5. Treatment prognosis. To illustrate need for proposed approach, four case studies recently...
Small reservoirs play an important role in providing water to rural communities. Increased construction of small mitigate the effects droughts leads a High-density Reservoirs Network (HdRN) reservoirs, which can potentially modify streamflows both dry and wet periods. However, there is lack understanding interannual behavior flow retention impact future increases number mainly for HdRN dryland catchments. This research aims determine possible increase on hydrological networks, evaluating...
Abstract This paper aims to understand the national-level policy change that occurred in Brazilian drought management, whereby shifted from reactive crisis management a preparedness approach. We found combination of factors supported change, such as interplay multiple events different regions country, length and timing these events, attention paid issue, role entrepreneurs political connecting solutions problem. The analysis is based on streams framework (MSF), which includes two windows...
To increase drought preparedness in semi-arid regions across the world many small and medium reservoirs have been built recent decades. Together these form a Dense Reservoir Network (DRN) its presence generates numerous challenges for water management. Most of that constitute network are unmonitored unregistered, posing questions on their cumulative effects strategic distribution at watershed scale. Their influence hydrological propagation is thus largely unexplored. The objective this study...
