Agroclimatology of West Africa: Burkina Faso

DUKES, M.D.; Bjorneberg, David L.; KLOCKE, N.L.

This paper is an introduction to the Advances in Irrigation Special Collection in this issue of Transactions ASABE and the next issue of Applied Engineering in Agriculture of 14 papers selected from 88 papers and presentations at the ASABE 5th Decennial National Irrigation Symposium, December 2010, in Phoenix, Arizona. This symposium followed the objectives of the previous four decennial events to provide a forum to assess progress of research endeavors to advance the effectiveness of irrigation practices during the past 10 years, leading to further research priorities that respond to future challenges. The papers in this Collection address a wide range of topics grouped into broad categories: microirrigation, center pivot irrigation, crop water use for...

An assessment of crop water productivity in the Indus and Ganges River Basins: current status and scope for improvement

AgEcon

Cai, Xueliang; Sharma, Bharat R.; Matin, Mir Abdul; Sharma, Devesh; Gunasinghe, Sarath.

The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.

Barbosa,Marcela L.; Silva,Thieres G. F. da; Zolnier,Sérgio; Silva,Servulo M. S. e; Morais,José E. F. de; Assis,Mery C. de S..

ABSTRACT This study aimed to understand the relationship of morphological characteristics and actual evapotranspiration of forage cactus clones with their productive capacity under different water regimes. The data used in this study were collected between the years 2012 and 2013, in Serra Talhada, State of Pernambuco. The clones Sertânia IPA - IPA, Miúda - MIU and Orelha de Elefante Mexicana - OEM were submitted to three irrigation depths (2.5, 5.0 and 7.5 mm) and three irrigation intervals (7, 14 and 28 days). Cladode and plant morphology, accumulated actual evapotranspiration and yield were obtained at the moment of harvest. Pearson’s correlation matrix was elaborated and, in the sequence, multicollinearity, canonical and path analysis were applied....

RESUMO: O cerrado possui aproximadamente 208 milhões de hectares sendo 49 milhões de pastagens cultivadas. O objetivo deste trabalho foi apresentar o balanço de energia na superfície de uma pastagem de Brachiaria brizantha cv. Marandu localizada na região central do cerrado (Planaltina - GO). O estudo foi realizado de 15/11 a 09/12/2001, inicio da estação chuvosa. foram instaladas, na área, uma estação micrometeorológica automática e um sistema de correlação dos vórtices. Foram obtidas as densidades dos fluxos dos principais componentes do balanço de energia: saldo de radiação (Rn), calor latente (LE), utilizadas nos processos evapotranspirativos, e calor sensível (responsável por variações na temperatura) no ar (H) e no solo (G).

Calibration methods for the Hargreaves-Samani equation

Ferreira,Lucas Borges; Cunha,Fernando França da; Duarte,Anunciene Barbosa; Sediyama,Gilberto Chohaku; Cecon,Paulo Roberto.

ABSTRACT The estimation of the reference evapotranspiration is an important factor for hydrological studies, design and management of irrigation systems, among others. The Penman Monteith equation presents high precision and accuracy in the estimation of this variable. However, its use becomes limited due to the large number of required meteorological data. In this context, the Hargreaves-Samani equation could be used as alternative, although, for a better performance a local calibration is required. Thus, the aim was to compare the calibration process of the Hargreaves-Samani equation by linear regression, by adjustment of the coefficients (A and B) and exponent (C) of the equation and by combinations of the two previous alternatives. Daily data from 6...

ABSTRACT The aim of this study was to evaluate the impacts of climate change on irrigation water demand of melon plants grown in Jaguaribe-Apodi Irrigation District (DIJA), which is located between the states of Ceará and Rio Grande do Norte, in Northeastern Brazil. Future scenarios were developed using the Eta-CPTEC/HadCM3 climate change projections, after being submitted to downscaling method. We used a set of climate data from the same model for the period of 1961 through 1990, and further projections after bias correction. Local geographic coordinates were interpolated using GIS techniques. Reference evapotranspiration (ETo) was estimated from the monthly minimum and maximum mean temperatures, using a limited data method. The rainfall, temperature,...

Climatic risk zoning allows the identification of areas of low risk of reduced crop productivity due to climatic events. In Brazil, losses to agriculture due to climate are mainly caused by drought. The objective of this research was to determine areas of low climatic risk for corn and palisade grass cultivated in integrated crop-livestock systems in Sao Paulo state. Corn varieties characterized by a 120-day growing cycle and soil with three different water holding capacities (sandy, medium and clayey soils) were considered. A daily water balance model was used to simulate planting dates between September and December. The water requirement satisfaction index (WRSI) was calculated for critical phenological phases of both cultures (germination, emergence...

Abstract: The objective of this work was to evaluate the performance of vineyard water indices in different grape-growing regions. The climate data used come from the historical series of weather stations located in 18 countries. The evaluated indices were the following: dryness, Zuluaga, humidity, aridity, moisture, and the grapevine water index. The grapevine water index and the indices of drought, moisture, and aridity exhibit similar performances, which makes them suitable to be used equivalently in climatological studies of grapevine regions.

A finalidade deste estudo e determinar qual dos quatro locais estudados no Nordeste (Caruaru, Serra Talhada, Surubim em Pernambuco e Senhor do Bonfim na Bahia) do ponto de vista de relações ambientais entre a cultura e o clima, e o melhor para se estabelecer um programa de pesquisa em sistemas de produção, visando a zona "semi-árida" (precipitação anual 600-1000 mm), desde que para a zona "muito-árida" (precipitação anual 250-600 mm), foi selecionado Petrolina, PE. Foram enfocados os aspectos gerais do relevo e meio ambiente dos quatro locais com descrição da área, solos, clima, vegetação, análise da precipitação.
