This paper examines a Rajasthan (India) drinking water supply project that relied on hybrid governance reforms in its original design. Decentralization and marketization, combined with a participatory approach, were intended to facilitate an empowering shift in state-citizen relationships. Paying citizens were expected to make quantity and quality demands of the state as consumers, not welfare beneficiaries. Research on the project 3 years after its completion revealed that although payment for water and community participation were intended to compel the state to provide clean water, they failed in this regard. The problem of an unreliable state supply was solved through small scale privatization, a decision ‘independently’ reached at the local scale, but one that served to further undermine the state’s ability to provide clean water.In this paper, we trace the shifts in regulation that evolved in the post-project phase at both the state and village scale that resulted in the delivery of contaminated water. Ethnographic research indicates that community participation was introduced as a set of institutions that would govern how villagers interacted with the state and its water supply, but villagers altered community participation by introducing reforms in water governance as a way of coping with an unresponsive state and increased work burden. Community participation evolved in contradictory ways as the impacts of neoliberal environmental governance were felt. The paper contributes to understandings of neoliberalization processes’ local impacts by analyzing their ongoing hybridization at multiple scales. It further calls into question foundational notions that community participation in resource governance is the appropriate solution to drinking water supply.  相似文献

High fluoride in groundwater has been reported from many parts of India. However, a systematic study is required to understand the behaviour of fluoride in natural water in terms of local hydrogeological setting, climatic conditions and agricultural practices. Present study is an attempt to assess hydrogeochemistry of groundwater in Ajmer district in Rajasthan to understand the fluoride abundance in groundwater and to deduce the chemical parameters responsible for the dissolution activity of fluoride. Ajmer district falls in the semi-arid tract of central Rajasthan and is geologically occupied by Precambrian rocks (granites, pegmatites, gneisses, schists etc) where groundwater occurs under unconfined condition. A total of 153 well-water samples, representing an area of 8481 km2 (further subdivided into eight blocks), were collected and chemically analyzed. The results of chemical analyses (pre-monsoon 2004) show fluoride abundance in the range of 0.12 to 16.9 mg/l with 66% of the samples in excess of permissible limit of 1.5 mg/l. Presence of fluoride bearing minerals in the host rock, the chemical properties like decomposition, dissociation and dissolution and their interaction with water is considered to be the main cause for fluoride in groundwater. Chemical weathering under arid to semi-arid conditions with relatively high alkalinity favours high concentration of fluoride in groundwater. Dental and skeletal fluorosis are prevalent in the study area which can be related to the usage of high fluoride groundwater for drinking. The suggested remedial measures to reduce fluoride pollution in groundwater include dilution by blending, artificial recharge, efficient irrigation practices and well construction.  相似文献

In light of the increasing deterioration of groundwater supplies in Rajasthan, India, rainwater harvesting practices in southern Rajasthan were studied to determine the effects of artificially recharged groundwater on the supply and quality of local groundwater. A physical and geochemical investigation utilizing environmental tracers (δ18O and Cl–), groundwater level and groundwater quality measurements, and geological surveys was conducted with two objectives: (1) to quantify the proportion of artificially recharged groundwater in wells located near rainwater harvesting structures and (2) to examine potential effects of artificial recharge on the quality of groundwater in these wells. A geochemical mixing model revealed that the proportion of artificial recharge in these wells ranged from 0 to 75%. Groundwater tracer, water table, and geological data provided evidence of complex groundwater flow and were used to explain the spatial distribution of artificial recharge. Furthermore, wells receiving artificial recharge had improved groundwater quality. Statistical analysis revealed a significant difference between the water quality in these wells and wells determined not to receive artificial recharge, for electrical conductivity and SO 4 – . The findings from this study provide quantitative evidence that rainwater harvesting structures in southern Rajasthan influence the groundwater supply and quality of nearby wells by artificially recharging local groundwater.  相似文献

This paper explores a series of maxims, widely known in policy and academic circles as the ‘principles of good governance’, which state that policymaking in the European Union (EU) should be participatory, conducted as close to citizens as practicable, transparent, accountable, effective and coherent. These maxims were introduced into EU fisheries management as part of a radical reform of the Common Fisheries Policy (CFP) in 2002. This reform was instituted in response to criticisms of a prevailing management regime alleged to be inefficient, undemocratic, and potentially responsible for an environmental crisis: the exhaustion of key fish stocks. The research for this work has found that there are limits to the actual achievement of good governance in EU fisheries. In practice governance innovations are very often contradictory and rife with tensions. I reason that such problems result not merely from policy implementation failures; they constitute a more endemic feature of the CFP reforms. We can begin to understand these limits to good governance principles by looking to Agamben’s permanent state of exception thesis. Agamben’s theory helps to show how these contradictions and tensions occur under new governance regimes, because the relationship between democratic norms (like good governance) and political power is no longer clear. I argue that this blurring has been exploited by groups seeking influence in these new regimes. They do this through citing a supposed need for emergency measures to mitigate crisis. Although this research broadly supports the state of exception thesis, my analysis leads me to question some aspects of its application in contemporary governance spaces.  相似文献

Groundwater accounts for about half of the water use for irrigation in India.The fluctuation pattern of the groundwater level is examined by observing rainfall replenishment and monitoring wells.The southern part of Rajasthan has experienced abrupt changes in rainfall and has been highly dependent on groundwater over decades.This study presents the impact of over-dependence on groundwater usage for irrigation and other purposes,spatially and temporally.Hence,the objective of this study is to examine the groundwater level trend by using statistical analysis and geospatial technique.Rainfall factor was also studied in groundwater level fluctuation during 2009-2019.To analyze the influence of each well during recharge or withdrawal of groundwater,thiessien polygonswere generated from them.In the Jakham River basin,75 wells have been identified for water level trend study using the Mann-Kendall statistical test.The statistics of trend analysis show that 15%wells are experiencing water level decline in pre-monsoon,while very low percentage of wells have such trend during post-monsoon season.The average rate of water level decline is 0.245 m/a in pre-monsoon and 0.05 m/a in post-monsoon.The aquifer recharge potential is also decreasing by year.it is expected that such type of studies will help the policy makers to adopt advanced management practices to ensure sustainable groundwater resource management.  相似文献

Over-exploitation of groundwater for agricultural crops puts stress on the sustainability of natural resources in the arid region of Rajasthan state, India. Hydrogeological study of groundwater levels of the study area during the pre-monsoon (May to June), post-monsoon (October to November) and post-irrigation (February to March) seasons of 2004–2005 to 2011–2012 shows a steady decline of groundwater levels at the rate of 1.28–1.68 m/year, mainly due to excessive groundwater draft for irrigation. Due to the low density of the groundwater observation-well network in the study area, assessment of groundwater draft, and thus groundwater resource management, becomes a difficult task. To overcome the situation, a linear groundwater draft model (LGDM) has been developed based on the empirical relationship between satellite-derived crop acreage and the observed groundwater draft for the year 2003–2004. The model has been validated for a decade, during three year-long intervals (2005–2006, 2008–2009 and 2011–2012) using groundwater draft, estimated through a discharge factor method. Further, the estimated draft was validated through observed pumping data from random sampled villages (2011–2012). The results suggest that the developed LGDM model provides a good alternative to the estimation of groundwater draft based on satellite-based crop area in the absence of groundwater observation wells in arid regions of northwest India.  相似文献

This paper examines, first, the conditions under which irrigating farmers are being alienated from their water through a state-led process of dispossession, and then, second, details the dialectical process of farmers’ resistance to these efforts. The paper advances recent scholarship on water grabbing and ‘accumulation by dispossession’ by drawing on a case from northwestern India to explore the connections between non-agrarian economic growth, irrigated agriculture and farmer livelihoods. Specifically, it examines an urban water infrastructure development project that aims to provide water to Jaipur, the Indian state of Rajasthan’s capital city, through the appropriation of an existing rural dam/reservoir complex built for irrigation and redirecting it to domestic, commercial and industrial uses. Drawing on an examination of policy documents and interviews with farmers and state planners, this paper argues that these transfers must be understood as a supply-side solution to support economic growth, where the lack of stable water supplies is a barrier to capital accumulation. The paper contributes to critical scholarship by showing that the processes underpinning water’s reallocation are specific acts of ongoing ‘dispossession’ through extra-economic means under advanced neoliberal capitalism, which alienates water away from peasant producers towards new centers of capital accumulation, dialectically creating peasant resistance to these efforts.  相似文献

In this paper I argue that geographies of religion are fundamental to understanding governance and social order in contemporary urban space. More specifically, I show how Foucault’s notion of governmentality characterizes regimes of power beyond the state apparatus, positing that religion and churches also produce and maintain the knowledges, truths, and social order associated with governmentality and self-regulated governance. By considering the geography of religion literature within the context of Foucualt’s work, I illustrate the importance of religious and spiritual practices to contemporary urban space, and the roles they play in producing and maintaining governance and socio-political order. My purpose is not to suggest that governmentality has been misapplied as a theoretical tool for understanding the state and political power, but to show how the term actually describes power more generally, including spiritual moments in addition to political ones. Drawing from my case study in Fortaleza, Brazil, I substantiate my theoretical argument using empirical examples, showing how governmentality is produced through religion and churches and the relationship between spiritual practices and governance in everyday space.  相似文献

The expansion of modern agriculture in developing countries presents numerous challenges for environmental policy makers. Environmental policies for agriculture in north-eastern Brazil’s soybean belt are analyzed, with emphasis on the role of a non-state actor in leading policy reforms. An organization representing large farmers is leading policy reforms to reduce the environmental impacts of modern agriculture. By contrast, state agencies are relatively weak and ineffective. The analysis situates this question conceptually in literatures stressing the political and structural causes of corporate environmentalism and literatures explaining the increasingly strong role of non-state actors in environmental governance. The case study focuses on the content of reforms, reasons why the non-state actor is so prominent, and the implications of policy reforms. State agencies face major challenges in environment-agriculture policy debates in places where environmental subsidies are unlikely, environmental information is poor, and organized private interests are influential.  相似文献

Groundwater resources in semi-arid areas and especially in the Mediterranean face a growing demand for irrigated agriculture and, to a lesser extent, for domestic uses. Consequently, groundwater reserves are affected and water-table drops are widely observed. This leads to strong constraints on groundwater access for farmers, while managers worry about the future evolution of the water resources. A common problem for building proper groundwater management plans is the difficulty in assessing individual groundwater withdrawals at regional scale. Predicting future trends of these groundwater withdrawals is even more challenging. The basic question is how to assess the water budget variables and their evolution when they are deeply linked to human activities, themselves driven by countless factors (access to natural resources, public policies, market, etc.). This study provides some possible answers by focusing on the assessment of groundwater withdrawals for irrigated agriculture at three sites in North Africa (Morocco, Tunisia and Algeria). Efforts were made to understand the different features that influence irrigation practices, and an adaptive user-oriented methodology was used to monitor groundwater withdrawals. For each site, different key factors affecting the regional groundwater abstraction and its past evolution were identified by involving farmers’ knowledge. Factors such as farmer access to land and groundwater or development of public infrastructures (electrical distribution network) are crucial to decode the results of well inventories and assess the regional groundwater abstraction and its future trend. This leads one to look with caution at the number of wells cited in the literature, which could be oversimplified.  相似文献

Using secondary data generated from three rounds (31st, 48th and 54th) of the National Sample Survey Organization (NSSO) of India, a macro-level estimate of the spread of markets for groundwater supported pump irrigation services in India was derived for two periods of time, 1976–1977 and 1997–1998. This estimate is the first of its kind that presents a spatio-temporal analysis of the markets for pump rental and irrigation services at an all-India level. The results, computed using simple statistics, show that the area irrigated through pump irrigation services has increased from an estimated 1.0 million ha in 1976–1977 to an estimated 20.0 million ha in 1997–1998. The analyses also calls into question two myths prevalent in literature, that these markets were under-developed in eastern India in the 1970s and 1980s, and that in recent times they are shrinking in southern peninsular India due to groundwater depletion. The policy implication is that there is a need for re-orientation in the way irrigation statistics are collected in India so as to include a category of hired irrigation services and establish a comparable survey design for future use.  相似文献

Critical researchers of underdevelopment have established a well-known record celebrating the environmental knowledges of subsistence communities in contested wildlife conservation zones. Similar battles are being fought over science, uncertainty, and wild animals in the American west, however, with far less attention to local epistemologies. Often dismissed as “barstool biology”, the ecological knowledges of local hunters in the Northern Yellowstone ecosystem are rooted in environmental experience and situated politics. How does local hunter knowledge diverge or converge with that of state officials, environmentalists, ranchers, and other constituencies, and to what effect on wildlife management policy? This paper seeks to answer that question, reviewing recent research amongst local resource users, managers, and activists in Montana. By rendering empirical the question of local knowledge around America’s oldest national park, rather than trying to “read it off” political affiliation, education, or livelihood, a clearer picture of power, knowledge, and conservation emerges. The results suggest that emerging management policies have developed from the discursive alliance of landowners, outfitters, and environmentalists, shifting priorities towards enclosure and exclusion in wildlife at the expense of other silent constituencies.  相似文献

在农业与生态系统用水相矛盾的干旱内陆区,地下水过度开采导致生态环境急剧恶化。以往对地下水的管理,以政府直接控制地下水使用为主,但效果并不十分理想,或管理成本较大。因此,寻求间接调控地下水使用的措施成为更好的选择。以河西走廊的石羊河、黑河和疏勒河流域为例,以农户问卷调查数据为依据,探究影响农户使用地下水的关键因素,以寻求通过制定更有针对性的政策来影响农户节约并高效利用地下水,最终达到农户自下而上自发节水的效果。分析结果发现：农户对地下水的使用在不同阶段有不同的特征,但均强烈地依赖于地表水供给,地表水供给每增加1个轮次,单位公顷耕地地表水用量会增加237.3 m3,相应会减少795.2 m3的地下水,整体上平均减少504.1 m3的总用水量,地下水占灌溉总用水的比例也会下降3.7%。此外,地下水的使用还与家庭经营规模、经营模式、地下水供给条件及经营者偏好等因素密切相关。因此,政府应根据流域内地表水与地下水的综合条件和特点,结合农业生产特征和农户偏好,因地制宜制定政府主导的管理政策与农户自我调节能力有效结合的开发治理制度和方案,切实实现区域水资源节约与高效利用双重目标。  相似文献

The ‘silent revolution’ is a phenomenon describing the individualistic behaviour of farmers in the adoption of intensive groundwater abstraction technologies, which in some cases has led to groundwater over-abstraction and environmental degradation in semiarid areas such as La Mancha, Spain. However, a lacuna exists as to the extent to which state politics have affected the development of groundwater abstraction technologies in Spain. With new quantitative and qualitative data from the irrigation community of Manzanares and public irrigation and colonisation plans, this report studies the adoption of groundwater abstraction technology and investigates the historical role of the state in the development of modern groundwater-fed irrigation socio-ecologies in the semiarid area of La Mancha in Spain.  相似文献

This paper deals with the changes brought about by the ‘reforms’ in water currently under way in many parts of the world. Three particular reforms in the state of Maharashtra in western India are discussed - the commercialization of a parastatal body, the concept of self-sufficiency as it plays out in the context of urban local bodies, and the working of the regulatory body in water. The analysis of these reforms shows how, in common with neoliberal projects elsewhere, changes in institutional practices are resulting in changes in subjectivities, foreclosing alternatives, and leading to attempts to ‘depoliticize’ the water arena. At the same time, there are differences between the regulatory experience of Maharashtra and regulation in other locales, which offers insights into how neoliberalism works in a context where water reforms have emerged relatively late.  相似文献

Groundwater use in India, and many developing countries, is linked to livelihood and well-being of village communities. It is, therefore, important to characterise groundwater behaviour and resilience and identify strategies that will help to improve the sustainability of groundwater supplies. The concept of Standardised Precipitation Index (SPI) has been widely used for analysing rainfall drought. In this study, we adapt SPI to understand watertable fluctuations and assess resilience of groundwater supplies vis-à-vis rainfall variability from one year to the next. The modified SPI, called Groundwater Resilience Index (GRI), represents a normalized continuous watertable elevation variability function. The index is applied to two districts, viz., Udaipur and Aravalli in Rajasthan and Gujarat, India, respectively, to assess its usefulness. To evaluate the association of rainfall variability with groundwater depth fluctuation, SPI was also calculated. The study showed that GRI varies less than SPI, indicating that groundwater availability is less variable than the rainfall in both districts. This means that groundwater increases reliability of water supply for irrigation in both districts. The estimated SPI and GRI at 6-month intervals for the study period show that even though the groundwater is not stressed (normal condition in 75% of the months observed), there is variation in resilience of the aquifer system to drought and extreme events. Overall, the study indicated that the proposed GRI can be a useful tool for understanding watertable fluctuations and assessing groundwater resilience, especially to prioritise areas for groundwater recharge when funds for recharge works are limited.  相似文献

Since 1960, South Asia has emerged as the largest user of groundwater in irrigation in the world. Yet, little is known about this burgeoning economy, now the mainstay of the region's agriculture, food security and livelihoods. Results from the first socio-economic survey of its kind, involving 2,629 well-owners from 278 villages from India, Pakistan, Nepal Terai and Bangladesh, show that groundwater is used in over 75% of the irrigated areas in the sample villages, far more than secondary estimates suggest. Thanks to the pervasive use of groundwater in irrigation, rain-fed farming regions are a rarity although rain-fed plots within villages abound. Groundwater irrigation is quintessentially supplemental and used mostly on water-economical inferior cereals and pulses, while a water-intensive wheat and rice system dominates canal areas. Subsidies on electricity and canal irrigation shape the sub-continental irrigation economy, but it is the diesel pump that drives it. Pervasive markets in tubewell irrigation services enhance irrigation access to the poor. Most farmers interviewed reported resource depletion and deterioration, but expressed more concern over the high cost and poor reliability of energy supply for groundwater irrigation, which has become the fulcrum of their survival strategy.

In most Latin American countries, issues concerning water governance and control also reflect broader conflicts over authority and legitimacy between the state and civil society. What lies behind the diverse water policy reforms is not simply a question of governing water affairs but also a drive to control or co-opt water user groups. This paper examines the efforts by the present Ecuadorian government to ‘control water users’ through new forms of ‘governmentality’ (Foucault, 1991). We use the ‘cathedral and bazaar’ metaphor (Lankford and Hepworth, 2010) to illustrate government rationale and practices in water governance shifts in the last decades. We analyze how Rafael Correa’s government sets out to reshape the relations between state, market and society. In its ‘Twenty-first Century Socialism’ project, based on a proclaimed ‘Citizen Revolution’, actual policy reform does not reverse but rather transforms the process of neoliberalizing water governance – creating a hybrid bazaar-cathedral model. We argue that the current water govermentality project implements reforms that do not challenge established market-based water governance foundations. Rather it aims to contain and undermine communities’ autonomy and ‘unruly’ polycentric rule-making, which are the result of both historical and present-day processes of change. Interestingly, water user federations that emerged during the neoliberal wave of the last two decades now claim water control space and search for new forms of democratizing water governance. They act as agents who fiercely – yet selectively and strategically – oppose both elements of the State-centered (cathedral) and market-based (bazaar) water governance models.  相似文献

Groundwater irrigation is the most predominant method used across India and about 50% of the total irrigated area is dependent on it. The state of Haryana has witnessed a spectacular increase in agricultural production in the last few decades, and is largely dependent on groundwater for irrigation. Groundwater mining for irrigation has become a reality in the state over the years as the number of tube wells has increased from 0.02 million in 1966 to 0.73 million in 2012, showing alarming signs of over-exploitation. The impact of increased groundwater irrigation on groundwater levels has not been studied both spatially and temporally. Therefore, this study has been undertaken to investigate the groundwater level fluctuations in the state using geographical information system (GIS) from the groundwater level data of 893 observation wells obtained from Groundwater Cell, Department of Agriculture, Government of Haryana, Panchkula, for the period 2004-12. Many researchers have applied GIS to reveal the spatial and temporal structure of groundwater level fluctuation and as a management and decision tool. The analysis of results indicated a mix of negative and positive trends in the groundwater levels. However, the negative trends were much more pronounced than positive ones. Groundwater level in the state ranged between 0.16 to 65.97 m from the ground surface and per cent area with groundwater level depth more than 10 meter (critical category) was about 56% in 2004 and has increased to 64% by 2012. The average annual decline in groundwater level was observed to be above 32 cm/year, with the strongest decline (108.9 cm/year) in Kurukshetra district.  相似文献

Extracted groundwater, 90% of which is used for irrigated agriculture, is central to the socio-economic development of India. A lack of regulation or implementation of regulations, alongside unrecorded extraction, often leads to over exploitation of large-scale common-pool resources like groundwater. Inevitably, management of groundwater extraction (draft) for irrigation is critical for sustainability of aquifers and the society at large. However, existing assessments of groundwater draft, which are mostly available at large spatial scales, are inadequate for managing groundwater resources that are primarily exploited by stakeholders at much finer scales. This study presents an estimate, projection and analysis of fine-scale groundwater draft in the Seonath-Kharun interfluve of central India. Using field surveys of instantaneous discharge from irrigation wells and boreholes, annual groundwater draft for irrigation in this area is estimated to be 212 × 106 m3, most of which (89%) is withdrawn during non-monsoon season. However, the density of wells/boreholes, and consequent extraction of groundwater, is controlled by the existing hydrogeological conditions. Based on trends in the number of abstraction structures (1982–2011), groundwater draft for the year 2020 is projected to be approximately 307 × 106 m3; hence, groundwater draft for irrigation in the study area is predicted to increase by ～44% within a span of 8 years. Central to the work presented here is the approach for estimation and prediction of groundwater draft at finer scales, which can be extended to critical groundwater zones of the country.  相似文献
