“…The expansion of irrigation and better management of existing water supplies can contribute to the increase of food production, playing an increasingly important role in agricultural production (Christofidis, 2013;Darko et al, 2015). The central pivot system is one of the most used, besides water can also be used for the application of fertilizers, insecticides and fungicides .…”

“…Irrigation is an activity that is in the process of expansion and should increase 20% (40 million ha) by 2030, particularly in developing countries (Darko et al, 2015). The estimated potential for growth in the world area with irrigation systems is about 180 million hectares, which potential Brazilian areas represent about 25 million hectares for sustainable development in new areas (Christofidis, 2013).…”

The use of irrigation has expanded and favored agricultural productivity in recent years. The mapping through remote sensing has contributed to the monitoring of irrigated areas. In this sense, the objective of this study was to evaluate the central pivotal evolution in terms of location by municipalities, micro basins, soils and slope in the Goian tributary watershed of the Araguaia River State of Goiás. Data were available between 2000 and 2016. Irrigated areas were surveyed through the database available in the Geographical Information System of the State of Goiás (SGEI). The vector and raster data were manipulated using the Qgis v software. 2.18.26 (QGIS Development, 2019). The pivots were counted through the statistical function of the software. From the shape SGEI available in the soil map of classes is generated by categorizes tion of soil types. The declivity map was generated from raster files acquired through the Brazilian Geo morphological Database (INPE, 2017). The slope classes (%) were extracted with slope tool. There is an increase of more than 95% in the number of pivots and irrigated area between the years 2000 and 2016. The central pivots are more concentrated in the central region of the Red and Red-Light basins. The highest concentration of central pivots occurred in the municipality of Jussara. The pivots are located predominantly in an Oxisol area with a slope of 3 to 13%.

Irrigation water is one of the limited resources and need to be managed efficiently in order to meet crop water requirement. Thus, water resources have to be utilized in such a manner as to protect and conserve the available water reserves in the most efficient way as possible to prevent unnecessary losses and water wastage. In view of this, the research evaluates the uniformity and water conveyance efficiency of spray tube irrigation system using sixty catch cans at different spacing intervals of 0.5 m x 0.5 m, 1 m x 1 m, 1.5 m x 1.5 m and finally with 2 m x 2 m. The results shows that value of Christiansen's coefficient of uniformity (CU) ranges from 87% to 92%, distribution uniformity (DU) ranges from 79% to 88% and scheduling coefficient (Sc) ranges from 1.13 to 1.27. Efficient performance and delivery of the spray tube irrigation system is envisaged to help cut down operational cost, water losses and to increase crop yield.

“…Appropriate innovations relative to irrigation management and practice are required to address the problem of water scarcity (Pereira et al, 2002). Local communities have the potential for creating and developing innovative problem solving approaches when enabled (Darko et al, 2016;Gorjestani, 2004) and a locally based approach has the potential to be highly effective and successful (Shortt et al, 2004). The farmers' irrigation committee in the study area when enabled, at least assured fair sharing of water within the scheme although they lack the capacity for overall efficient and effective management of the scarce water resource.…”

“…A participatory approach can enable local stakeholders to create and develop problem solving innovations and/or rules (Darko et al, 2016;Gorjestani, 2004). A locally based approach has a higher potential to be effective, efficient, and equitable than externally imposed rules (Ostrom, 1990;Shortt et al, 2004).…”
