analysis of water market distributiveimpacts • determinants of peasants’participation in the water market Objectives: Perspectives: • peasant agriculture • agricultural sector • non-agricultural sectors Where?: • Limarì Province • research area of previous studies on the efficiency of water market • highly representative of the Chilean agriculture transformations
The water market in Chile (Código de Aguas, 1981) • water can be privately exploited through transferable use rights • water property rights are separable from land property rights - ‘real’ rights - divisible - mortgageable - no use priorities • only demand and supply will determine the resource allocation • the State only guarantees the rules of the game.
The state of the art (I): efficiency (Theoretical) pros of private water market vs. public provision (Hearne and Easter, 1997): • concentrate resources in higher-value uses better allocation • more rational resource use conservation • higher share of private investments public budget savings
The state of the art (I): efficiency Real effects of the water market: • positive assessment: • - Gazmuri (1994): more efficient water allocation • - Holden and Thobani (1995): infrastructures and institutional • competencies • - Ríos e Quiroz (1995): water scarcity and infrastructure • flexibility • - Bauer (1997): incentive to investment and flexibility • negative assessment: • - Peña and Retamal (1992): marketpower and asymmetric • information • - Barrientos (1995): few transactions • - Bauer (1997): “ “
The state of the art (I): efficiency The water market in Limarì province : • By and large: pros > cons • Hearne and Easter (1995): «the market transfer of water-use rights does produce substantial economicgain-from-trade. [These economic gains] are about three times the value of each water share from the Cogotí dam.» • But, in the Limarí valley: • low transaction costs (on average, 0.02% for buyers and 0.05% for sellers) • presence of the reservoir storage (Cogotí dam), modern infrastructures (gated canals, flow meters, etc.) and well organized userassociations.
The state of the art (II): distributive effects • Theoretically: neutrality, provided that there is • access to information • no market power • extension and technical assistance • Practically: • positive effects • - Gazmuri (1994) and Thobani (1995): poverty reduction, thanks to trickle downeffects • negative effects • - Ríos and Quiroz (1995) and Bauer (1997): peasants disadvanta- • ged because of lack of knowledge about new procedures,lack of • financial resources, and weak bargaining power
The state of the art (II): distributive effects The water market in Limarì province (Hearne and Easter, 1995): «the market transfer of water-use rights does produce substantial economicgain-from-trade. These economic gains occur in inter-sectoral trades and in trade between farmers, and they produce rents for both buyers and sellers. Yet buyers, especially large table-grape producers (…), receive higher rents than sellers.» Consistent with the broader Chilean context of «exclusionary growth» (Carter and Barham, 1996).
The case study (I): market functioning Analysis of allregistrations (both original registrations and transfers) of rights among agents which took place between 1981 and 1997 in Limarí Province. Water market is a very active institution in Limarí Province: • total registrations: 1,367 • yearly average: 80.4 • corrected yearly average: 39.3 • market transactions: 84% of total registrations

Conclusions • Private water market has become a very active institution in the Limarí valley • But, there are evidences that the market is highly imperfect: • - asymmetric information • - barriers to entry due to social, cultural, economic, and • institutionalconditions existing among different agents • The distribution of water resources isheavily • unbalancedand it tended to worsen: • - general decrease in the amount of per capita rights • - accumulation of resources by the most powerful social-economic • groups • - peasants are the group that suffered the greatest loss: water is a • strategic determinant of agricultural development
Conclusions • Determinants affecting peasants’ participation and behaviour in the water market: crucial role of the variables relative to information, education and participation in agricultural organisations and in water users associations potential role of government interventions in: • - training of human resources • - promotion of adequate and accessible information for the • whole population
Conclusions • Distribution dynamics influenced by the Government’s abdication from its role as ‘referee’ of the game (consequence of the radically liberalistic environment where the reform was designed and implemented) • The Concertaciòn Governments’ ‘growth with equity’ objective has not been achieved
