Entre as atividades que necessitam de água, a irrigação é considerada a mais exigente em termos de volume. O objetivo deste estudo foi identificar e quantificar a distribuição espacial dos sistemas de irrigação do tipo pivô central e linear móvel licenciados e em operação no Rio Grande do Sul, de tal forma que estas informações possam ser aplicadas na otimização da gestão de recursos hídricos. O conjunto de dados utilizado no estudo foi fornecido pela Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler (FEPAM) e consistiu-se de coordenadas geográficas associadas aos sistemas de irrigação licenciados. Os sistemas de irrigação do tipo pivô central e linear móvel foram distribuídos nas doze principais bacias hidrográficas do Rio Grande do Sul. Verificou-se que há 1.285 equipamentos do tipo pivô central e linear móvel licenciados pela FEPAM, que irrigam uma área total de 91.849 ha. A maior concentração destes sistemas de irrigação está na região noroeste do estado, especialmente nas bacias hidrográficas do Alto Jacuí e Ijuí. Na região Sul, do Rio Grande Sul, apenas alguns sistemas do tipo pivô central e linear móvel foram observados, podendo este fato ser parcialmente atribuído à predominância de irrigação por inundação na cultura do arroz. Palavras-chave: Gestão de recursos hídricos, bacia hidrográfica, irrigação.  Manke, E.

E.IDENTIFICATION OF IRRIGATED AREAS BY CENTER PIVOT AND MOVING LATERAL IN STATE OF RIO GRANDE DO SUL  2 ABSTRACT Water scarcity in some Brazilian regions makes water resources management greatly important. Among the activities that need water, irrigation is considered the most demanding in terms of volume of water, and Rio Grande do Sul is one of the states in Brazil with the largest agricultural production. The objective of this study was to identify and quantify the geographical distribution of licensed center pivot and linear moving irrigation systems operating in Rio Grande do Sul state such that information can be applied to optimize water resources management. The main dataset used in the study was provided by Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler (FEPAM) and consisted of geographical coordinates associated with the aforementioned licensed irrigation systems. These irrigation systems were distributed on the twelve main watersheds in Rio Grande do Sul state. There are 1,285 center pivot and linear moving equipments licensed by FEPAM, which irrigate an area of 91,849 ha. The greatest concentration of this irrigation system is in the Northwestern of Rio Grande do Sul state, especially in Alto Jacuí and Ijuí watersheds. On the other hand, only a few of such systems were observed in South region of Rio Grande do Sul state and this can be partially attributed to the predominance of flood irrigation for rice. Keywords: water resources management, watershed, irrigation.

The Impact

The amount of water consumed in the agricultural sector in Iran is higher than the global average and this necessitates more attention to proper water management in this sector. Due to the climatic conditions of Iran, the average rainfall in most areas is lower than global rainfall. That is to say, the water issue is one of Iran's most important concerns or the greatest challenge for the people of this land. Examining the current agricultural situation indicates that despite the increased agricultural production potential due to the lack of a proper management system, optimal utilization of available resources has not become possible and droughts and reduced rainfall and increasing population followed reduce the amount of water consumed in the agricultural sector. The present study investigates the impact of agricultural water resources management on the economic development of rural settlements (Case study: Villages of Zebarkhan district of Neyshabur city). This research is applied in terms of purpose and in terms of descriptive and analytical method and library and field methods have been used for data collection. According to the results of the present study and data analysis regarding the amount of water consumed in the study area, it was observed that the amount of water consumed per hectare for all crops in modern management lands was less than the fields where managed by the traditional way. This suggests that modern science-based scientific management has played a key role in reducing the loss of water resources within the scope of this study, and in contrast, water loss in farms that are managed in traditional ways is so high. Also, regarding the production efficiency in the study area, the results showed that the production efficiency per hectare for all crops was significantly higher than that under traditional management. This rate varied between 25 to 57.1%.

A utilização de técnicas de irrigação visando a produção agrícola tem apresentado crescimento nos últimos anos, sendo que o sistema de irrigação por pivô central (PC) também avançou no quantitativo de unidades implantadas e no total de área abrangida. Isto se deve às características desse tipo de sistema, as quais mostram-se vantajosas para o produtor rural, tais como economia de mão-de-obra e facilidade de operação, entre outras. O formato circular deste tipo de sistema facilita sua identificação através de técnicas de Geoprocessamento aplicadas nas análises de imagens orbitais ou aéreas, permitindo análises quantitativas e de espacialização. Neste contexto, o presente trabalho teve como objetivo mapear, por meio de imagens orbitais, as áreas irrigadas por PC no período de 11 anos (2004 a 2015) referente à três regiões que possuem destaque na produção agrícola no Estado de Mato Grosso: Médio Norte, Parecis e Sudeste. A região Médio Norte apresentou taxa média de crescimento anual de 10,96% na sua área irrigada, a região Sudeste 6,75% e a região dos Parecis 4,28%. A evolução média no número de pivôs nestas áreas foi da ordem de 8,07% ao ano, passando de 259 unidades em 2004, para 586 no ano de 2015, totalizando um crescimento de 226,25% no período.Palavras-chave: áreas irrigadas; produção agrícola; geoprocessamento; sensoriamento remoto. SPACE-TEMPORAL ANALYSIS OF THE OCCURRENCE OF CENTRAL PIVOT IRRIGATION SYSTEMS IN AGRICULTURAL REGIONS IN THE STATE OF MATO GROSSO ABSTRACT:The use of irrigation techniques in agricultural production has increased in the last years, and the center-pivot irrigation system has advanced in number of implanted units. This system, due to its characteristics such as labor savings and ease of operation, has proved to be advantageous for the rural producer.

Irrigation Demand

The Indus Basin Irrigation System (IBIS) is more than a century old. Water allowances and canal water distributions responded to increasing crop water requirements in a southward direction, e.g. higher water allowance in Sindh as compared to Punjab. But within a province, the canal water supplies do not address the issue of difference in irrigation demand. The consequence is unprecedented groundwater depletion in Bari Doab and waterlogging in certain other canal commands. After the Indus Waters Treaty of 1960, gradually reduced flows and ultimate desiccation of eastern rivers have also contributed towards falling groundwater levels of adjoining aquifers. In this study, water allocations in the Water Apportionment Accord of 1991, annual average canal water diversions, and irrigation demand were compared for canal commands in Punjab. Rainfall was taken as an ultimate source of water that has a beneficial impact in integration with canal and groundwater. It is concluded that the efficiency of existing irrigation systems can be improved by adopting the concept of integrated water resources management (IWRM). Thus, to avoid waterlogging and groundwater depletion, reallocation of canal water supplies amongst the irrigation units in Punjab, in proportion to the relative irrigation water demand and cropping intensities, is recommended.

Spatio-temporal distribution of irrigation water components was evaluated at the canal command area in Indus Basin Irrigation System (IBIS) by using a remote sensing-based geo-informatics approach. Satellite-derived MODIS product-based Surface Energy Balance Algorithm for Land (SEBAL) was used for the estimation of the actual evapotranspiration (ETa). The ground data-based advection aridity method (AA) was used to calibrate and validate the model. Statistical analysis of the SEBAL based ETa and AA shows the mean values of 87.1 mm and 47.9 mm during Kharif season (May–November) and 100 mm and 77 mm during the Rabi Season (December–April). Mean NSEs of 0.72 and 0.85 and RMSEs 34.9 and 5.76 during the Kharif and the Rabi seasons were observed for ETa and AA, respectively. Rainfall data were calibrated with the point observatory data of the metrological stations. The average annual ETa was found 899 mm for defined four cropping years (2011–2012 to 2014–2015) with the minimum average value of 63.3 mm in January and the maximum average value of 110.6 mm in August. Average of the sum of net canal water use (NCWU) and rainfall during the study period of four years was 548 mm (36% of ETa). Seasonal analysis revealed 39% and 61% of groundwater extraction proportion during Rabi and Kharif seasons, dependent upon the occurrence of rainfall and crop phenology. Overall, the results provide insight into the interrelationships between key water resources management components and the variation of these through time, offering information to improve the strategic planning and management of available water resources in this region.
