Indicadores de desempenho aplicados a projetos públicos de irrigação: distrito de irrigação Curaçá I, BA.

Abstract

Public irrigation projects depend on modern management; The general objective of this research is to quantify and qualify, through indicators and their respective indexes, the performance of the system called the Curaçá Public Irrigation Project 1 - BA. To achieve this goal it is necessary to survey, analyze and represent the data, in time and space. with selection and application of indicators and their respective performance indices related to the water balance, operation and maintenance services, sustainability of irrigable areas and the economic performance and the demand and consumption of electricity. THE overall consumption ratio (RGC) that provides system reliability indices, when analyzed in the annual period, presents the values ​​of 0.91 and 0.99 relative to the biennium 2008/2009. respectively within the required operating range which is 0.70 - 1.00, but monthly perimeter shows indices that are out of range acceptable would be 0.60 - 1.U). From 2004 to 2030, the consumption ratio (RCM) whose executive project benchmark is 1,500 m3 ha-1, it is verified that the that the average values ​​above the planned ones are inserted in the months of August to November. The irrigable area occupation ratio (ROAI) ​​presents annual average above the unit over the period 2004 - 2010, which indicates a irrigated area in the smallholder sector, while business area! It is underused and with a drastic reduction in the irrigable area. The from the year 2010. Considering the water productivity ratio (RPA '), the average indices of sectors 111 and 112, year 2009, were below the regional average; in sector 122, the average index found 6 of 2.70 Kg m '\ electricity consumption and demand, year 2009, forum 0.50 kWh ha "', 0.53 kWh m "3 c, 0.48 kW ha" 1, 0.51 kW ra "\ respectively, indicating that the demand for electricity follows consumption rates by charging energy costs electrical system. Overall, the project indicates aspects of reliability, equity and efficiency to its users.
