Agricultural Water Demand in Guadalquivir River (2005 Value vs. 2015 Scenario) AgEcon
Mesa-Jurado, Maria A.; Berbel, Julio; Piston, Juan Maximo.
This paper reviews the application of a scenario for the 2015 agricultural policy and markets for the irrigated agriculture in Europe. Scenarios for irrigated agriculture 2015 are described in detail including Reformed CAP and how biofuel impacts demand. A model for irrigation water demand is applied at the basin level for the Guadalquivir River (Southern Spain). The methodology is based upon residual value of water and it combines budget and farm analysis at municipality level, with the Guadalquivir basin divided at 50 counties where 24 possible crops are selected and adapted specifically to each county yield and costs. The result is a comparative analysis between actual level of water use and value, and 2015 scenario at county level and later aggregated...

ALTERNATIVE APPROACHES ON CONSTRUCTING A COMPOSITE INDICATOR TO MEASURE AGRICULTURAL SUSTAINABILITY AgEcon
Gomez-Limon, Jose Antonio; Riesgo, Laura.
The aim of this paper is to carry out a comparative analysis of alternative methods on constructing composite indicators to measure global sustainability of the agricultural sector. This comparison is implemented empirically on the irrigated agriculture of the Duero basin (Spain) as a case study. For this purpose, this research uses a dataset of indicators previously calculated for different farm-types and policy scenarios. The results allow to establish a hierarchy of the policy scenarios on the basis of the level of sustainability achieved. Furthermore, analyzing the heterogeneity of different farms-types in each scenario, is also possible to determine the main features of the most sustainable farms in each case. All this information is useful in order...

Cadastral maps of irrigated areas by center pivots in the State of Minas Gerais, using CBERS-2B/CCD satellite imaging REA
Ferreira,Elizabeth; Toledo,Joice H. de; Dantas,Antonio A. A.; Pereira,Rafael M..
Medium-resolution satellite images have been widely used for the identification and quantification of irrigated areas by center pivot. These areas, which present predominantly circular forms, can be easily identified by visual analyses of these images. In addition to identifying and quantifying areas irrigated by center pivot, other information that is associated to these areas is fundamental for producing cadastral maps. The goal of this work was to generate cadastral mapping of areas irrigated by center pivots in the State of Minas Gerais, Brazil, with the purpose of supplying information on irrigated agriculture. Using the satellite CBERS2B/CCD, images were used to identify and quantify irrigated areas and then associate these areas with a database...

IMPLAN UNDERSTATES AGRICULTURAL INPUT-OUTPUT MULTIPLIERS: AN APPLICATION TO POTENTIAL AGRICULTURAL/GREEN INDUSTRY DROUGHT IMPACTS IN COLORADO AgEcon
McKean, John R.; Spencer, William P..
Synthesized input-output models are widely used by industry and government economists. The IMPLAN program is popular because it provides user access to the base data so that modifications can be made. The Washington survey-based model and IMPLAN for Washington State are compared, and differences in multipliers are traced to differences in final payments leakages. An adjustment technique for IMPLAN is demonstrated. An application is made to a Colorado potential drought impact analysis. More than 51,000 part- and full-time jobs and $1.6 billion of household income are at stake in the Colorado farm and "green industry" sectors.

Introducing Different Land Uses (Irrigated and Non-Irrigated) in Policy Analysis Modelling for Mediterranean Countries AgEcon
Casado, Jose Maria; Gracia, Azucena.
The arable crop sector in Spain is highly dependent of the Community subsidies and account for 33% of total transfers received by the Community. Then, it is expected that the introduction of the Single Farm Payment (SFP) will drive important changes in the arable crop production in Spain. The quantitative assessment of the SFP impacts on the arable crop sector in Spain is the overall objective of this paper. To achieve this goal, an econometric, dynamic, multi-product and partial equilibrium commodity model has been built disaggregating between irrigated and non-irrigated land use for cereals called Spanish Econometric Simulation of Agricultural Policies (SESAP). Results indicated that the introduction of the SFP has only induced considerable changes...

Opinion publica sobre la multifuncionalidad del regadío: el caso de Castilla y Leon AgEcon
Gomez-Limon, Jose Antonio; Gomez-Ramos, Almudena.
This paper analyses the demands from the society of Castilla y León (Spain) regarding its agricultural sector through the valuation of the relevance of its productive and non-productive functions. Additionally, it assesses the level of social satisfaction concerning the performance of these functions by irrigated agriculture in this region. For this purpose primary data colleted through a survey has been used. Results obtained show that the average citizen does not perceive a higher utility from irrigated agriculture compared with the whole agricultural sector. For these agricultural systems the social function is the element of multifunctionality considered most relevant regarding the perceived social welfare. Resumen Este trabajo analiza las demandas...

Organic matter decomposition and microarthropod community structure in corn fields under low input and intensive management in Guaira, SP. Repositório Alice
RODRIGUES, G. S.; LIGO, M. A. V.; MINEIRO, J.L. de..
The rate of organic matter decomposition and the structure of the communities of microarthropods were compared between two corn fields receiving cantrasting agricultural management practices (low input and intensive farming). The rate of decomposition tended to be higher in the intensively managed field in the beginning of the growing season, but decreased to a level significantly lower than the observed in the low input field by the end of the growing season. This suggested that the biological community associated with the decomposition process could be negatively influenced in the intensively managed field. Analyses of the structure of microarthropod communities indicated differences between the two areas. The microarthropod populations present in the...

Reference evapotranspiration estimation by the Irrigameter in Southern Tocantins State, Brazil AGRIAMBI
Giovanelli,Luan B.; Oliveira,Rubens A.; Oliveira-Filho,Jair C.; Baptestini,Júlio C. M.; Delazari,Fábio T.; Sediyama,Gilberto C..
ABSTRACT The choice for the most appropriate method to estimate evapotranspiration depends on the availability of meteorological data, required level of precision and cost of equipment acquisition. For this estimate, the Irrigameter is simple to operate, precise and economically viable to farmers. In addition, it collaborates in the application of the necessary water depth to crops, thus avoiding unnecessary energy consumption, environmental degradation, and increasing crop yield and improving crop quality. In this context, the objective of this research was to estimate the reference evapotranspiration using the Irrigameter, for the climatic conditions of the Southern Tocantins state, Brazil. The experimental design was completely randomized with...

Soil Compressibility under Irrigated Perennial and Annual Crops in a Semi-Arid Environment Rev. Bras. Ciênc. Solo
Watanabe,Rafaela; Figueiredo,Getulio Coutinho; Silva,Álvaro Pires da; Neves,Júlio César Lima; Oliveira,Teogenes Senna de.
ABSTRACT In irrigated soils, a continuous state of high moisture reduces resistance of the soil to applied external forces, favouring compaction. The aim of this study was to evaluate the susceptibility to compaction of developed calcareous soils in irrigated annual and perennial cropping systems of the Apodi Plateau, located in the Brazilian semi-arid region. Four areas of irrigated crops were evaluated: banana after two (B2) and 15 (B15) years cultivation, pasture (P), and a corn and beans succession (MB), as well as the reference areas for soil quality and corresponding natural vegetation (NVB2, NVB15, NVP and NVMB). Samples were collected at layers of 0.00-0.10 and 0.20-0.30 m; and for B2 and B15, samples were collected in the row and inter-row spaces....

The impact of reforming the Common Agricultural Policy on the sustainability of the irrigated area of Central Italy. An empirical assessment by means of a Positive Mathematical Programming model AgEcon
Cortignani, Raffaele; Severini, Simone.
The Common Agricultural Policy (CAP) is a major driver of the environmental and social sustainability of the agriculture in the European Union (EU). Under the 2003 CAP reform, most direct payments to agricultural producers were decoupled from production. This work assesses the possible impact of the CAP reform on the sustainability of an irrigated area of Central Italy with particular attention being paid to decoupling. The analysis has been conducted using the Positive Mathematical Programming (PMP) method that directly estimates the cost function parameters by imposing the first-order conditions of the farm model under consideration. The analysis assesses the impact of the CAP reform on farm cropping patterns, water and chemical use, labour use and...

Turning Water into Carbon: Carbon sequestration vs. water flow in the Murray-Darling Basin AgEcon
Schrobback, Peggy; Adamson, David; Quiggin, John C..
Large scale forest plantations in the Murray-Darling Basin may be embraced as a carbon sequestration mechanism under a Carbon Pollution Reduction Scheme. However, increased tree plantation will be associated with reduced inflows to river systems because of increased transpiration, interception and evaporation. Therefore, an unregulated change in land management is most likely to have a dramatic impact on the water availability. This will exacerbate the impacts of climate change projected in the Garnaut Review. This paper examines the implications of unrestricted changes in land use. These results should suggest the true costs to society from carbon sequestration by determining the tradeoffs between timber production and agricultural products.
