Setembro, 2005
Global

Az árvízvédelmi töltések védelmében, az árvizek levonulásában, ezáltal ma-gában az árvízvédelemben a gyepesítésnek jelentős szerepe van. Gazdaságossá-gát nem lehet egzakt módon bizonyítani, hiszen míg a létesítési és fenntartási költségeket egyértelműen meghatározhatjuk, a bevételi oldal összetett és nehezen számszerűsíthető. Az árvízvédelmi földgátak gyepesítésének társadalmi hasznossága és gazda-sági előnye mégis vitathatatlan:-közvetlen gazdasági haszon: pl.

Fluid dynamics: Water, knowledge, and power in the Mekong Delta

Journal Articles & Books
Novembro, 2014
Vietnam

ABSTRACTED FROM THE FIRST TWO PARAGRAPHS: Over the past several years, the enormity of the environmental challenges facing the Mekong River Delta region of southern Vietnam has become increasingly clear. Climate change and dam construction on the upper reaches of the Mekong threaten to disrupt the flow of the river, making both droughts and floods ever more common. Meanwhile, the rapid intensification of rice agriculture in the Mekong Delta and the export-oriented cultivation of farmed fish and shrimp have increasingly strained.

In today’s agriculture, maize is considered to be one of the major feed, food and industrial crops. Cultivation of maize by inappropriate agricultural practices and on unsuitable sites is connected with specific risks of soil degradation, mainly due to water erosion of the soil.

Where Do Ecosystem Services Come From? Assessing and Mapping Stakeholder Perceptions on Water Ecosystem Services in the Muga River Basin (Catalonia, Spain)

Peer-reviewed publication
Setembro, 2020

Espanha

Reductions in water availability and increasing rainfall variability are generating a narrative of growing competition for water in the Mediterranean basin. In this article, we explore the distribution and importance of water resources in the Muga River Basin (Catalonia, Spain) based on key stakeholders’ perceptions. We performed a sociocultural evaluation of the main water ecosystem services in the region through stakeholder interviews and participatory mapping.

Proportional Variation of Potential Groundwater Recharge as a Result of Climate Change and Land-Use: A Study Case in Mexico

Peer-reviewed publication
Setembro, 2020
México
Estados Unidos

This work proposes a methodology whereby the selection of hydrologic and land-use cover change (LUCC) models allows an assessment of the proportional variation in potential groundwater recharge (PGR) due to both land-use cover change (LUCC) and some climate change scenarios for 2050. The simulation of PGR was made through a distributed model, based on empirical methods and the forecasting of LUCC stemming from a supervised classification with remote sensing techniques, both inside a Geographic Information System.

Applying Ostrom’s institutional analysis and development framework to soil and water conservation activities in north-western Ethiopia

Peer-reviewed publication
Janeiro, 2018
Etiópia

Sustainable land management is of utmost importance in Ethiopia and relies on Soil and Water Conservation (SWC) measures collectively implemented by smallholders through participatory processes. This paper contributes systematic evidence on how SWC strategies are implemented and how participation is operationalized.

Exploring watershed conservation and water governance along Pangani River Basin, Tanzania

Peer-reviewed publication
Outubro, 2015
Tanzania

Water scarcity is among the contemporary problems of our time across the globe. The problem is worsened by policy failures to enforce water governance and watershed conservation. Consequently, it has curtailed the capacity of watersheds to release hydrological services, water in particular. We carried out this study to explore approaches for watershed conservation and investigate water governance challenges in Pangani River Basin, Tanzania. We collected data by using structured questionnaires and meetings with different actors in the study area.

What makes decisions about urban water infrastructure forward looking? A fuzzy-set qualitative comparative analysis of investment decisions in 40 Dutch municipalities

Peer-reviewed publication
Fevereiro, 2019
Global

Municipalities worldwide are confronted with the need to take long-term decisions about ageing water infrastructure in the face of unpredictable future developments. Previous studies on long-term decision making have proposed solutions targeted at the domain of either politics or planning. This study combines insights from the domains of policy, politics, and planning by using the Multiple Streams Framework to explain what enables municipalities to take forward-looking investment decisions.

Outsourcing governance in Peru’s integrated water resources management

Participatory water governance has become highly influential around the world as a means for managing water resources. Scholars and practitioners advocate for the inclusion of previously marginalized communities in water resources management through the devolution of power, responsibility, and participation. Where community institutions are weak or missing, experts recommend strengthening or re-building them to enable inclusive decision-making over water resources.

City planners, urban innovators and researchers are increasingly working on ‘future city’ initiatives to investigate the physical, social and political aspects of harmonized urban living. Despite this, sustainability principles and the importance of urban groundwater are lacking in future city visions. Using London as a case study, the importance of groundwater for cities is highlighted and a range of future city interventions may impact on groundwater are reviewed.
