Water policies and legal framework in India

The paper tries to look at the legal frameworks in the water sector in India, from the first laws drafted during British India to the revisions and additions post independence. It talks about the provisions in the law as well as the flaws and omissions and suggests an examination of and strengthening of the existing water laws and policies to address the problems of environment, ecology, equity and development. There is a need to devise an alternative socio-legal discourse and practice where the concerned authorities use organic knowledge of water resource management as seriously as the scientific knowledge, and work a consideration of people’s struggles for water resource management as pursuit of human rights.Length: pp.569-585Water policyWater lawLegislationHistoryInstitutions

Agriculture, Water Resources and Water Policies in Italy

This paper provides an overview of the Italian water management system, with particular reference to the links between agriculture and water resources, and emphasis on underground resources. Our objective is mainly descriptive at this level; nonetheless, we try to evaluate patterns of interaction between agriculture and water resources policy from the point of view of water sustainability. After a short description of the main hydrologic and institutional aspects, the paper goes into the analysis of the most important issues and ongoing policies. We show that the link between agriculture and groundwater is but very weak in "Mediterranean" Italy. While most of the pollution problems regard Northern Italy - that resembles much more continental Europe than Mediterranean countries with respect to hydrologic and climatic patterns - the use of the water table for irrigation is restricted to only a few areas, since most of the agricultural water is derived from surface resources. On the other side, agriculture remains by far the largest water user in Italy, and one of the primary causes of pollution.Water Policy; Environmental Impact of Agriculture; Groundwater Protection; Environmental Policy Instruments

Sustainability of water use in agriculture. Southern european farmers participation and social impact.

Abstract This paper aims to open a discussion in the scientific point of view and policy making processes on sustainability of water policies. The social and environmental impact on the Agriculture sector in Southern European countries (Greece, Italy, Portugal and Spain) will be investigated to analyse the adoption of measures taken by decision makers on water policies. The community assets of farmers will have an important role on the implementation of different strategies concerning agriculture water management. The paper will focus on the role of farmer’s participation as central actors of implementation in water policy. Furthermore, the social and the environmental aspects will be addressed

The effects of water policies on the farm sector in the Western Cape

The farm sector of the Western Cape is modelled using a sector mathematical programming model to determine the effect of different water policies on output, prices, welfare and employment. Two scenarios are analysed, namely the effect of a restriction of water available for irrigation, and an increase in water tariffs. Results show a relative shift away from (intensive) irrigated production, and a decrease in producer welfare, especially for irrigation farmers, under both scenarios. When water availability is decreased, the negative effect falls disproportionately on the poor as employment decreases. In the long run the negative effects are severe, as there is a relative shift out of industries where the Western Cape has a competitive advantage.Resource /Energy Economics and Policy,

Price induced water irrigation: Unraveling conflicts and synergies between European agricultural and water policies

The 2003 CAP reform considerably affects cropping patterns in European agriculture. At the same time the imperatives of the forthcoming Water Framework Directive (WFD) is expected to modify irrigation decisions especially in Southern Europe where irrigated agriculture utilizes about 70-80% of total water. This paper examines the combined effect of CAP reform and the application of likely volumetric water pricing on water demand by taking into account three drivers of change, namely extensive margin changes, intensive margin changes and irrigation technology shift. For low rates of water prices, CAP reform contradicts the WFD objectives since it leads to cropping patterns that consume more water resources. On the contrary, as water prices increase, decoupling and water pricing display a synergistic effect on water conservation. Finally, decoupling substantially increases the efficiency of water pricing in terms of water conservation. As a result, the post CAP reform regime clearly dominates the prior CAP reform regime when an index of value for money water conservation is examined.irrigation, bio-economic modeling, mathematical programming, policy analysis, price endogenous model, water demand, CAP reform, WFD

Investigations on the Impacts of China's Rural Water Policies: From Efficiency and Equity Perspectives

China’s water resources are scarce. Given its limited water resource, policies in China have been traditionally focused on meeting sectoral demands for water by increasing the supply rather than managing demand. However, effective water resource policies that focus on demand management and encourage efficient water use remain the main weakness of China’s water policy. Main potential for efficiency gain is the agricultural sector, which accounts for 65 percent of the nation’s total water withdrawals. Due to major inefficiencies in irrigation water systems only about 45 percent of water withdrawals for agriculture are actually used by farmers to irrigate their crops. In addition to inefficiencies, the equity of the agricultural water policies is questionable, That is, existing policies lead to an inequitable allocation across different parts of the basin and within a given irrigation system. Designing policies that are both efficient and equitable is a challenge that has yet to be met. In this paper we explore the potential for an improvement in policies that address water use efficiency and equity in one of China’s rural regions. A spatial water allocation model is employed to maximize water use efficiency at both public water conveyance system and private on-farm water use in one of the irrigation districts in Northwest China’s Shaanxi Province. First-hand data which were collected from our field survey will be used in the water allocation model. Water is provided by a government authority via a public canal to farmers. Water use efficiency is modeled along with efficient and optimal cropping patterns to be endogenously determined by the decision makers in the region. The public water conveyance system has a given efficiency that can be improved with investment to reduce deep percolation. This can be done either by farmers or through cost sharing arrangements between farmers and the government. Pumping water from the canal is not regulated and sequencing of the farmers along the canal dictates the amount of water to be used by each farmer. Under the unregulated case equity may be the lowest, where the upstream users may pump unrestricted amounts and the downstream users may use the remainder. Increased efficiency of the public canal may lead to more available water to the upstream users. In a parallel venue, when on-farm efficiency is improved, less water is returned to the aquifer, leaving less water as a return flow to be available to the downstream users. Hence equity is always an issue whenever efficiency is improved. Specifically in our study area farmers’ lands are covered by one irrigation authority and situated along a canal. All farmers have access to public canal water and groundwater. For those situated at plain area, where winter wheat is grown, they have better access to abundant and cheap public canal water. For those farmers living at hilly, higher elevation area, where apple production is dominating, they get water from public canal with a higher price of about 40% compared with the price their counterparts at the plain area due to an additional (stage 1 station) lift-height pumping cost. At last, water will be delivered to mountainous area where corn is grown. A stage 2 lift-height pumping station lifts the water again to irrigate the corn’s fields. Consequently the water price is doubled as compared to the original water price at the plain area. Corn needs less water than wheat and apple. Farmers may reduce their water costs either by reducing canal water application, and groundwater pumping, or by dry land farming. A canal controller or examiner will be introduced to the canal management. By doing so, the policy impacts of regulated and unregulated cases are analyzed. Our framework includes water use efficiency, water pricing and various policy interventions that are aimed at both increasing total welfare and improve income distribution along the canal. We show how important it is for the public agency and the private users to cooperate in order to achieve water use efficiency and equity within the irrigation network. Policies include various water pricing schemes, the unregulated case, increased monitoring and enforcement of various water allocation methods, cost sharing arrangements, side payments, and trade in water rights (that will be allocated by the government). A General Algebraic Modelling System (GAMS) is employed to achieve the optimization process under the water system constraints and other policy regulation constraints.Water efficiency, Equity, China’s rural water management, Environmental Economics and Policy,
