Comparison of two remote sensing models for estimating evapotranspiration: algorithm evaluation and application in seasonally arid ecosystems in South Africa

Author: Dzikiti, Sebinasi ; Jovanovic, Nebojsa ; Bugan, Richard DH ; Ramoelo, Abel ; Majozi, Nobuhle P ; Nickless, Alecia ; Cho, Moses A ; Le Maitre, David C ; Ntshidi, Zanele ; Pienaar, Harrison H Date: Sep 2019 Remote sensing tools are becoming increasingly important for providing spatial information on water use by different ecosystems. Despite significant advances in remote sensing based evapotranspiration (ET) models in recent years, important ... Read more
Physiological responses of a fynbos legume, Aspalathus linearis to drought stress

Author: Lotter, D ; Valentine, AJ ; Van Garderen, EA ; Tadross, M Date: Jul 2014 Aspalathus linearis (rooibos) is a medicinally and economically useful shrub which is endemic to the Mediterranean west coast region of South Africa. Species distribution modelling indicates potentially severe consequences in range shift for ... Read more
Response of Eucalyptus grandis trees to soil water deficits

Author: Dye, PJ Date: Jan 1996 The use of potential transpiration models to simulate transpiration rates in areas prone to soil water deficits leads to overestimates of water use as the soil dries. Therefore, the author carried out studies on Eucalyptus grandis W. Hill ex ... Read more
Seasonal variation in canopy reflectance and its application to determine the water status and water use by citrus trees in the Western Cape, South Africa

Author: Dzikiti, Sebinasi ; Verreynne, SJ ; Stuckens, J ; Strever, A ; Verstraeten, WW ; Swennen, R ; Theron, KI ; Coppin, P Date: Aug 2011 This study describes the diurnal and seasonal dynamics of the canopy reflectance, water use and water status of Midknight Valencia citrus trees under semi-arid conditions. Hyperspectral canopy reflectance data was collected on 30 trees at ... Read more
