Citizen science for hydrological risk reduction and resilience building

Wiley Interdisciplinary Reviews Water, Journal Year: 2017, Volume and Issue: 5(1)

Published: Oct. 24, 2017

In disaster risk management (DRM), an emerging shift has been noted from broad‐scale, top‐down assessments toward more participatory, community‐based, bottom‐up approaches. Arguably, nonscientist local stakeholders have always played important role in knowledge and resilience building within a hydrological context, such as flood response drought alleviation. However, rapidly developing information communication technologies the Internet, smartphones, social media already demonstrated their sizeable potential to make creation multidirectional, decentralized, diverse, inclusive. Combined with for robust low‐cost sensor networks, ‘citizen science’ approach recently emerged promising direction provision of extensive, real‐time management. Such projects work best when there is community buy‐in, purpose(s) are clearly defined at outset, motivations skillsets all participants well understood. They great enhance creation, not only data collection, but also analysis or interpretation. addition, they can serve means educating empowering communities that bypassed by traditional generation processes. Here, we review state‐of‐the‐art citizen science context reduction building.

Himalayan waters at the crossroads: issues and challenges

International Journal of Water Resources Development, Journal Year: 2015, Volume and Issue: 31(2), P. 151 - 160

Published: April 3, 2015

The Hindu Kush Himalayas are called the water towers of Asia as they source 10 major rivers and have largest snow ice deposits outside two poles. Water emanating from HKH provides food, energy ecosystem services to up 1.3 billion people. Climate change socio-economic demographic changes put unprecedented pressure on these resources, leading uncertain supplies, increased demands higher risks extreme events like floods droughts. eight articles in this special issue highlight various dimensions Himalayan resources by focusing both physical social science aspects management.

Achieving water security in Nepal through unravelling the water-energy-agriculture nexus

International Journal of Water Resources Development, Journal Year: 2019, Volume and Issue: 37(1), P. 67 - 93

Published: Dec. 23, 2019

This article investigates water security in Nepal from the perspective of water-energy-agriculture (food) nexus, focusing on pathways to that originate actions and policies related other sectors. It identifies promoting development Nepal's hydropower potential provide energy for pumping as way improve agriculture. Renewable groundwater reserves 1.4 billion cubic meters (BCM), an estimated available balance 6.9 BCM, could be pumped irrigate 613,000 ha rainfed agricultural land Terai plains, with a direct economic gain USD 1.1 annually associated benefits including promotion energy-based industry, food local employment. Governance also plays important role addressing security. We conclude nexus-based approach is required effective management governance.

Multi-Objective Optimization for Analysis of Changing Trade-Offs in the Nepalese Water–Energy–Food Nexus with Hydropower Development

Water, Journal Year: 2017, Volume and Issue: 9(3), P. 162 - 162

Published: Feb. 24, 2017

While the water–energy–food nexus approach is becoming increasingly important for more efficient resource utilization and economic development, limited quantitative tools are available to incorporate in decision-making. We propose a spatially explicit framework that couples two well-established water power system models develop decision support tool combining multiple objectives linear objective function. To demonstrate our framework, we compare eight Nepalese development scenarios based on five objectives: minimization of deficit, maintenance availability irrigation food self-sufficiency, reduction flood risk, environmental flows, maximization export. The deterministic multi-objective optimization model resolved enable realistic representation linkages accounts transmission constraints using an optimal flow approach. Basin inflows, hydropower plant specifications, reservoir characteristics, rules, demand, requirements, line properties provided as inputs. trade-offs synergies among these were visualized each scenario under demand requirements. Spatially disaggregated outputs allowed comparison not only fulfillment but also compatibility with existing infrastructure, supporting identification projects enhance overall efficiency. Though applied from perspective here, it can be extended adapted other problems.

Published: Feb. 27, 2018

Institutional arrangements shape water-related decision making and water policies, drive behaviours related to sharing use. It is therefore crucial that researchers, policy makers managers understand institutions. This article reviews critically assesses the current knowledge of institutional arrangements. explains how researchers explore structures, emergence change. details institutions are considered as a response social-environmental issues through design, fit bricolage.

The state as a stimulator of wastewater treatment policy: a comparative assessment of three subnational cases in central Mexico

Journal of Environmental Policy & Planning, Journal Year: 2019, Volume and Issue: 21(2), P. 134 - 152

Published: Jan. 29, 2019

River basin management and decentralisation reforms are promoted worldwide for solving water pollution problems. In Mexico, governmental efforts have been made to operate wastewater treatment plants countrywide, but federal administrations not achieved their intended outcomes. Acknowledging the role of governance in implementation policy, this paper analyses three cases central Mexico addresses question: How does context affect policy Mexico? A assessment tool is applied answer question. The allows an understanding paired with a comparative case study design. Data was collected through semi-structured interviews documents reviews. results indicate that mainly restricts policy. all subnational cases, river reached objectives. By comparing we found state level can play relevant decrease fragmentation increase coherence Therefore, strengthening involvement government improvement mechanisms limit political machinations supportiveness context.

Rural out-migration and water governance: Gender and social relations mediate and sustain irrigation systems in Nepal

Rural out-migration is changing agrarian political economies and natural resource governance worldwide, gender social relations play an important mediating role. The aim of this study to investigate the impact rural on collective action in farmer-managed irrigation systems, with a particular focus household structure relations. We employ mixed-methods approach combining survey (n = 377) ten villages conducted early 2021 80 qualitative interviews, 12 group discussions participant observations two carried out between 2015 Far Western Nepal. Using descriptive statistics as well univariate multivariate analyses, we explore migration patterns, functionality systems based system maintenance, mobilization, satisfaction water allocation conflict management. Our results show that 60.7% all households had at least one migrant past five years, which 83% were male. find labor not affected by male out-migration. Absent men’s contributions are successfully substituted women. Furthermore, participation user groups or committees significantly higher households. Lastly, findings revealed no effect crop yields. These challenge generalizability widespread assumptions deteriorating community-based management expand debates “loss labor” areas “deagrarianisation” due analysis contributes current studies effects societies demonstrating sustaining role governance.
