“…However, it does not occur due to the water deficit characteristic of the season (Santos et al, 2010;IBGE, 2016), except the area occupied by the IS -in the riparian zone -since rainfall and R G control the ET a , as reported by Scott et al (2000), requiring both climatic variables to occur concomitantly (Figure 2A).…”

“…The highest and lowest mean BIO are distributed in the summer (64.21 kg ha -1 day -1 , SDY 15) and winter (5.50 kg ha -1 day -1 , SDY 255), respectively ( Figure 2B) and correspond to the climatic seasonality and high heterogeneity of the region (Santos et al, 2010;IBGE, 2016), a prove of that is the BIO annual amplitude of 58.71 kg ha -1 day -1 . Mean values of 9.17 and 10.98 kg ha -1 day -1 were recorded during the dry period in the years 2013 and 2014 in the Mula stream's watershed, by Coaguila et al (2015), also in Santa Fé do Sul.…”

A B S T R A C TThe Cabeceira Comprida stream's watershed, located in Santa Fé do Sul, São Paulo state, has great environmental importance. It is essential for supplying water to the population and generating surpluses for sewage dilution. This study aimed to evaluate the annual performance of the components of water productivity from Landsat-8 images of 2015, using the Simple Algorithm for Evapotranspiration Retrieving (SAFER), calculating the actual evapotranspiration (ET a ), biomass (BIO) and water productivity (WP). The annual averages of ETa, BIO and WP were 1.03 mm day -1 , 36.04 kg ha -1 day -1 and 3.19 kg m -3 , respectively. The average annual values of ET a for land use and occupation were 1.40, 1.23, 1.05, 0.97 and 1.08 mm day -1 for the remaining forest (RF), invasive species (IS), pasture (Pa), annual crop (AC) and perennial crop (PC), respectively, with BIO of 57. 64, 46.10, 36.78, 32.69, 40.03 kg ha -1 day -1 for RF, IS, Pa, AC and PC, respectively, resulting in WP of 3.94, 3.59, 3.25, 3.09, 3.35 kg m -3 for RF, IS, Pa, AC and PC, respectively. The ETa, BIO and WP adjust to the seasonality of the region, and RF and IS stood out with the highest values.Produtividade da água estimada pelo SAFER -Simple Algorithm for Evapotranspiration Retrieving em bacia hidrográfica R E S U M OA Bacia Hidrográfica do Córrego Cabeceira Comprida localizada no município de Santa Fé do Sul-SP, tem grande importância ambiental, sendo imprescindível para o abastecimento de água à população e para gerar excedentes para a diluição do esgoto gerado. Assim, este trabalho avaliou o comportamento anual dos componentes da produtividade da água a partir de imagens do Landsat-8 do ano 2015, utilizando-se o 'Simple Algorithm for Evapotranspiration Retrieving' (SAFER), sendo calculadas a evapotranspiração atual (ET a ), a biomassa (BIO) e a produtividade da água (PA). As médias anuais da ETa, BIO e PA foram 1,03 mm dia -1 , 36,04 kg ha -1 dia -1 e 3,19 kg m -3 , respectivamente. As ETa médias anuais por uso e ocupação do solo foram 1,40, 1,23, 1,05, 0,97 e 1,08 mm dia -1 para mata remanescente (MR), espécies invasoras (EI), pastagem (Pa), cultura anual (CA) e cultura perene (CP), respectivamente, enquanto que as BIO apresentaram 57,64, 46,10, 36,78, 32,69, 40,03 kg ha -1 dia -1 para MR, EI, Pa, CA e CP, respectivamente, resultando em uma PA de 3,94, 3,59, 3,25, 3,09, 3, para MR, EI, Pa, CA e CP, respectivamente. As ET a , BIO e PA se ajustam à sazonalidade climática da região destacando-se a MR e as EI com os maiores valores.

A B S T R A C TThe climatic aptitude proposes to characterize the meteorological elements that most act in the behavior of the crops and, in their extreme conditions, will significantly interfere the growth and development of the plant. The objective of this study was to determine the climatic aptitude, aiming to identify the productive potential of the cashew, forage palm and corn crops, based on climate indicators, considering the natural variability of the pluviometric regime, established according to the crop requirement, of the method adopted to obtain the climatic water balance was the one proposed by Thornthwaite & Mather (1948, 1955, with spreadsheets elaborated by Medeiros (2016) that counts soil water, in which precipitation represents gain and loss evapotranspiration of soil moisture, and the values corresponding to the Water Surplus (EXC) and Water Deficiency (DEF) can be estimated. Based on this methodology, the available soil water storage capacity (CAD) of 100 mm was estimated. Rainfall data were acquired from the Northeast Development Authority and the Pernambuco Water and Climate Agency for the period between 1920 and 2016. For large-scale planting requires adequate planning for the use of cultivars that are more resistant to temperatures and humidity indexes, since water scarcity in the municipality, as well as rainfall is irregularly distributed, causing the soil to have a balance water for six to seven months of the year. It is recommended that the corn crop be used as a sower culture and its adaptation is conditioned to planting within the rainy season. Keywords: Evapopluviograma, pluvial regime, deficiency and water surplus. R E S U M OA aptidão climática propõe caracterizar os elementos meteorológicos que mais atuam no comportamento das culturas e, que em suas condições extremas, venham interferir sensivelmente o crescimento e desenvolvimento da planta. O estudo objetivou determinar a aptidão climática, visando identificar o potencial produtivo das culturas do cajueiro, palma forrageira e milho, com base em indicadores de clima, considerando a variabilidade natural do regime pluviométrico, estabelecida de acordo com a exigência da cultura, utilizou-se do método adotado para obtenção do balanço hídrico climático foi o proposto por Thornthwaite & Mather (1948, 1955, com elaboração de planilhas eletrônicas realizadas por Medeiros (2016) que contabiliza a água do solo, em que a precipitação representa ganho e a evapotranspiração perda de umidade do solo, podendo-se estimar os valores correspondentes ao Excedente Hídrico (EXC) e Deficiência Hídrica (DEF). Com base nesta metodologia foi estimada a capacidade de armazenamento de água disponível no solo (CAD) de 100 mm Os dados pluviométricos foram adquiridos da Superintendência do Desenvolvimento do Nordeste e da Agencia Pernambucana de Água e Clima para o período entre de 1920 e 2016. Para o plantio de larga escala é necessário um planejamento adequado para a utilização de cultivares mais resistentes

Energy balance with Landsat images in irrigated central pivots with corn crop in the São Paulo State, Brazil

et al. 2014

The energy balance (EB) components were quantified in a commercial farm with corn crop, irrigated by central pivots, in the Northwestern side of São Paulo state, Southeast Brazil. The SAFER (Simple Algorithm For Evapotranspiration Retrieving) was applied to retrieve the latent heat flux (λE), considering six pivots, covering irrigated areas from 74 to 108 ha. With λE quantified and considering soil heat flux (G) as a fraction of net radiation (R n), the sensible heat flux (H) was acquired as a residual in the energy balance equation. Seven Landsat satellite images, covering all corn crop stages from 23 April 2010 to 29 August 2010, allowed relating the energy balance components according to the accumulated degree-days (DD ac) from the planting to harvest dates. The average R n values ranging from 5.2 to 7.2 MJ m-2 day-1 , represented 30 to 45% of global solar radiation (R G). Considering the variation of the energy balance components along the corn crop growing seasons, the average ranges for λE, H and G were respectively 0.0 to 6.4 MJ m-2 day-1 ,-1.5 to 6.7 MJ m-2 day-1 and 0.1 to 0.6 MJ m-2 day-1. The fraction of the available energy (R n-G) used as λE was from 0.0 to 1.3 indicated a good irrigation management, insuring that the water deficit could not be the reason of any yield reduction. Although R n did not reflected well the crop stages, its partition strongly depended on these stages. λE higher than R n and the negative H/R n , happened sometimes along the corn growing seasons. This occurred after the vegetative growth and before the harvest times, indicating heat advection from the surrounding areas to the irrigation pivots, which represented an additional energy source for the evaporative process. The models applied here with only the visible and infrared bands of the Landsat sensor are very useful for the energy balance analyses, considering the size of the corn crop irrigation pivots in Southeast Brazil, when subsidizing a rational irrigation water application in corn crop.
