This paper provides an empirical basis for local water-governance reforms in the Philippines using primary data from 299 water managers representing water districts, community-based water organizations, irrigators’ associations and local government water providers. Survey results showed that local water organizations are subject to various forms of laws and regulations; there are no set bases for water price determination; and water administration set-up varies from the formal to the loosely informal structures. Recommendations are offered towards responsive local water governance arrangements. 相似文献

Bunot Lake exhibits the worst conditions among the seven crater lakes of San Pablo City in the Philippines. It is the most polluted lake, being oversaturated with fish pens/cages. It also hosts the largest concentration of illegal settlements. These attributes strongly suggest that Bunot Lake merits much greater attention in the agenda of its two administrative agencies, the Laguna Lake Development Authority (LLDA) and the City Government. The reality, however, is that Bunot Lake is lacking key development initiatives and programmes and seems to occupy a low priority to the LLDA and the City Government. This reality is particularly perplexing as the lake is located very near the urban centre, is closest to the premier lake (Sampaloc Lake), and is the site of the first commercial production of tilapia in floating cages in the city. Against this background, the present study identifies and analyses the immediate development issues for Bunot Lake. It contends that Bunot Lake should be given preference by the LLDA and the City Government, specifically by: (i) modifying their model‐template approach; and (ii) taking steps to tackle a basic need of Bunot Lake, namely the formulation of a zoning‐development plan. The present study also was designed to directly address the lacuna in Philippine lake studies, namely the paucity of research under the social science perspective (which is currently dominated by the natural science perspective) and on small lakes (which is currently concentrated on the largest lakes in the country). 相似文献

This paper analyses the enabling conditions for a water governance model responsive to future Philippine water requirements. Using the stage-based approach to institutional reforms, it assesses the outcomes of previous water governance reforms, such as conflicts in customary and formal rules; urban and rural; upstream and downstream; and the contestations in water supply privatization in Metro Manila. The analysis suggests that past water governance reforms were symbolic and procedural, and structural changes to support the legal frameworks were not achieved. Based on the case findings, the authors support the current reform agenda of implementing a decentralized framework of water governance at a watershed scale. 相似文献

Climatic variation and intersectoral water competition increasingly challenge the effective provision of irrigation services. This article explores their combined effects on irrigation allocation from the Angat Reservoir (Philippines), where domestic water use in Metro Manila has overtaken regional irrigation as the dominant right-holder. Rules protecting Metro Manila’s large right to water ‘interact’ with dry spells to affect irrigation security in wet and dry seasons. Historically, irrigators were uncompensated because re-allocation’s cause was contested as (1) an unforeseeable climatic event (releasing domestic utilities of liability), or (2) produced by urban demand (requiring compensation). Trade-off rules must be prepared to navigate combinatory effects. 相似文献

This study examines the development of Pandin Lake, a small lake in the Philippines, particularly the unconventional evolution of the ecotourism enterprise for the lake and the accompanying issues. The study concludes that Pandin Lake ecotourism development is mainly an endogenous initiative and that the intervention of the relevant administrative agencies is critical in addressing the contemporary issues. This study discusses the following issues: (i) the reasons for studying small lakes in the Philippines; (ii) Pandin Lake and its administration; (iii) the ecotourism enterprise evolution and issues regarding the lake; and (iv) the conclusions. It also addresses the extant gap in Philippine lake literature: specifically the scarcity of scholarly works on development‐oriented studies, noting the field is dominated by limnology and aquaculture studies, and on small lakes, noting the field concentrates heavily on studies of big lakes. 相似文献

This study examined the current governance system for Lake Buhi, Philippines. It describes stakeholder patterns of decision‐making, their roles in the decision‐making process based on their legal mandates, the manner of interactions, the sources of conflict and how these various issues are currently resolved. Stakeholders represent diverse interests, including irrigation, hydropower generation, fishery management and navigation. This study uses data generated from ten key informant interviews of the different stakeholders, information from five round table discussions, and secondary data and reports of various agencies. The results indicate that Lake Buhi and its watershed present classic man‐in‐nature governance challenges. The interplay of internal and external uncertainties regarding multiple uses results in a complex system that is difficult to effectively manage. Climate‐related hazards aggravate the pressures from activities within the lake watershed, complicating water allocation issues. The institutional arrangements that have emerged to address these challenges, however, appear to be fraught with overlaps, fragmentation and a lack of communication. It is thought these deficiencies could be addressed by establishing a lake basin council with representation from all the involved organizations, as well as any stakeholder groups not represented by organizations. The system of governance over the lake must address issues concerning water uses and access to the resource. The capacity of the organizations to participate in such an arrangement is weak, however, and capacity building is needed. The availability and sharing of data and information among stakeholders are also weak and must be strengthened if the work of the lake basin council is to be based on the best available information. 相似文献

Boundary organizations are institutions that interface between science and policy by facilitating interactions between scientists, policy specialists, and other stakeholders to inform collaborative decision-making. Natural resource management in the Great Lakes Basin is complex and a shared exercise among two federal governments, eight states, two provinces, and over 200 sovereign Tribes, First Nations, and Métis. Many governmental agencies have recognized a need to effectively engage with other jurisdictions in order to bridge the gaps between scientific knowledge and policy decisions. As a result, boundary organizations have emerged to facilitate planning and implementation of collaborative governance frameworks. This commentary highlights how decades of shared governance of the world’s largest freshwater surface water system is augmented and assisted by boundary organizations in addressing two key Great Lakes management issues – Western Lake Erie Basin nutrient levels and Lake Michigan fisheries – which are complex, broad in scale, and pose challenges that must be addressed collaboratively across jurisdictions. While there are many governmental and non-governmental entities that engage in boundary organization-like behaviors, this commentary will be centered on three key institutions: The Great Lakes Executive Committee’s Annex 4 (Nutrients) Subcommittee, the Great Lakes Commission, and the Great Lakes Fishery Commission. We illustrate how each organization procedurally engages stakeholders, especially within state and provincial jurisdictions, to produce information and products that add breadth and capacity to manage the ecosystems of the Great Lakes. We also highlight areas of success and opportunities for improvement in collaborative governance frameworks now and into the future. 相似文献

The present study examines water governance challenges in the Songkhla Lake Basin (SLB) with the aim of evaluating and analysing policies, legislations, regulations, institutions and actors responsible for the current state of the basin. The present study adopted three methodological approaches, including literature reviews, face‐to‐face expert interviews and field survey to investigate governance challenges confronting the SLB. It identified six major governance challenges that combined to produce current barriers to sustainable governance, resulting in depletion and deterioration of the SLB resource system. Moving forward will require pursuit of better resource management and governance systems, which will require strengthening of the Songkhla Lake Basin Committee to play a much needed coordinating and policy harmonization role to promote coherent actions among the formal and informal actors in the basin. Review of existing water resources and related governance instruments to make them appropriate, adequate and relevant for the sustainability of the SLB also is essential. 相似文献

Despite being designated the first UNESCO Biosphere Reserve in Malaysia, the Chini Lake Basin experiences continuing management challenges attributable to existing sectoral management practices and differences in demands of multiple stakeholders. Accordingly, a socio‐economic survey and stakeholder consultative process were undertaken, involving relevant stakeholders in the lake basin. The consultative process involved: (a) identification and prioritization of relevant stakeholders; (b) assessment of their socio‐economic activities and perceptions; (c) organization of focus group discussions between basin stakeholders; and (d) development of management recommendations in collaboration with stakeholders. The results of this study indicated the local community's way of living has changed from traditional occupations to a wage economy. Overlapping functions and lack of communication were among the major identified challenges facing by Chini Lake. Multiple strategies were proposed to promote environmental protection and good governance of Chini Lake, including formation of special area plans and strengthening institutional arrangements to sustainably manage the Chini Lake catchment. An effective authority also is necessary to improve communication and coordination of programmes by the various basin agencies and communities. 相似文献

The people of the Hindu Kush Himalayan region face severe seasonal water shortages due to the high variability in rainfall, and the problem is likely to be exacerbated under climate change. Small-scale local water storage options offer a means of collecting monsoon precipitation to provide for agricultural and household needs over the entire year, and they help build community resilience. Proper watershed management, with due consideration of upstream–downstream linkages, and appropriate institutional arrangements are vital for this adaptation measure to work. Active participation of local users in decisions related to water allocation and community services is essential. Planned interventions should preserve the institutional arrangements of reciprocity and cooperation among community members. 相似文献

The management of French freshwater bodies (lakes, reservoirs, ponds, etc.) needs to face the challenges imposed by the effects of climate change and by legal requirements to develop standards for water temperature and other physicochemical indicators. While 1D hydrodynamical models could be helpful in improving the knowledge of the thermal and hydrodynamic behaviour of French water bodies, the scarcity of data for calibration and validation, in addition to the unavailability of some forcing data, makes their application difficult for most French water bodies. In this article we explore an alternative statistical approach that takes advantage of the available data in order to inform future modelling applications. We used official monitoring data and satellite measurements to study the thermal characteristics of more than 400 French water bodies (depth: 1–310 m, surface area: 0.1–577 km2, volume: 0.1–89,000 hm3). The objective was to identify the importance of size on their thermal behaviour. For this we analysed the annual temperature cycle, the summer temperature profiles and within-lake spatial variability. Together with size, geography and transparency determine the thermal behaviour of water bodies through complex interactions. As a result of the analysis we propose a classification of French water bodies as a function of depth and surface area that reflects the summer vertical temperature gradient and the processes influencing the deepening of the thermocline. 相似文献

Stakeholder analysis and social network analysis were used to analyze stakeholders’ social and structural characteristics based on their interests, influence and interactions in Lake Naivasha basin, Kenya. Even though the Kenyan government and its agencies seem to command higher influence and interest in water resource management, the presence of influential and central stakeholders from non-government sectors plays a key role in strengthening partnership in a governance environment with multiple sectors, complex issues and competing interests. Interactions in the basin are guided by stakeholders’ interest and sphere of influence, which have both promoted participation in implementing a collaborative water governance framework. 相似文献

以巢湖优势种淡水贝类——环棱螺与表层沉积物为研究对象,采用HNO_3-HF-HClO_4全消解法消解,然后使用电感耦合等离子体发射光谱仪(ICP-AES)对二者重金属(Cd,Cr,Cu和Pb)的总量分布进行研究,同时运用潜在生态风险指数法及单因子污染指数法与均方根综合指数评价二者重金属风险。结果表明:巢湖沉积物均已受到了一定程度的重金属Cd,Cr,Cu,Pb污染,其中以Cd的潜在生态风险最大,而环棱螺中则以Pb和Cr为高风险元素;重金属的分布特征和相关性分析显示,巢湖沉积物中的重金属来源具有相似性,而环棱螺对重金属的积累因多种环境因素的综合作用,使得环棱螺体内的重金属来源不同。因此,在未来的巢湖环境治理过程中,可着重考虑对重金属Cd,Cr,Pb的治理,同时应加大对贝类等生物监测措施的应用。 相似文献

Lake Urmia (Urumieh in Persian) in north-western Iran is one of the largest permanent hyper-saline lakes in the world and the largest lake in the Middle East. It has numerous ecological, economic and social implications in terms of biodiversity, climate, species, habitat, tourism and recreation. However, during the past decade, the lake has shrunk significantly and its depth has fallen by almost 6 m. Contrary to other studies that have focused on the geomorphology of the lake, this study analyses the socio-environmental impact and provides a sustainable adaptive governance management model for its revival. This study reveals that unless various stakeholders and affected parties are actively involved in an implementable adaptive governance model, the fate of the lake will remain uncertain. 相似文献

Lake Chivero in Zimbabwe was shown to be hypereutrophic. Historical data showed that the eutrophication process had been arrested in the late 1970s. However, a combination of poor planning, multiplicity of jurisdiction, mismatch between rate of urbanization and waste management investment, recent changes in the local climate and a permissive, immature political system that called for no public accountability resulted in environmental management breakdown leading to hypereutrophication of the lake. The case of Lake Chivero is presented as an example of a wider global issue regarding the status of environmental management in competition with other priorities in emerging democracies. 相似文献
