Assessment of LAI derived from HLS Landsat Sentinel-2, S2 THEIA, and SNAP for crops in Bekaa (Lebanon)

Mourad, Roya (9/23/2020)

Background: Leaf area index (LAI) is an essential indicator of crop development and growth. Proper satellite-based LAI estimates at the farm-level often require near-daily imagery at medium to high spatial resolution. The ...
A COMPARATIVE STUDY OF THE FARMING SYSTEMS IN UGANDA, KENYA, AND TANZANIA TO ENHANCE PRODUCTIVITY

Aguti, Grace (5/9/2023)

Small-scale farming is the backbone of the agricultural sector in East Africa, contributing to food security, rural livelihoods, and poverty reduction. This study aimed to identify the challenges and opportunities facing ...
COMPARISON OF EVAPOTRANSPIRATION MEASURED FROM SURFACE RENEWAL SYSTEMS, EDDY COVARIANCE SYSTEMS, AND BOUNDARY LAYER SCINTILLOMETER OVER A POTATO FIELD IN THE BEKAA VALLEY

Rahal, Georges Albert (2/10/2023)

An accurate estimation of the heat fluxes and evapotranspiration (ET) is important to evaluate water requirements of crops and thereby optimize irrigation management. Familiar ET sensing methods include Eddy Covariance ...
Comparison of Surface Renewal and Eddy Covariance Estimates of Sensible Heat and Evapotranspiration over a Small Vineyard in a Semi-Arid Heterogeneous Landscape

Doughan, Abdul Razzak (12/20/2022)

Evapotranspiration (ET), evaporation from water surfaces and soil and transpiration from plants, is a key factor in irrigation scheduling and agricultural water management. Sensible and latent heat fluxes are the main ...
EFFECT OF EXCESS NITROGEN FERTILIZATION ON TRITICALE PRODUCTION UNDER RAINFED AND SUPPLEMENTAL IRRIGATION CONDITIONS

Abu-Altemen, Mudhafar (5/18/2022)

Triticale (Triticosecale Wittmack) is an annual human-made cereal that belongs to the family Poaceae. It is an important crop in various regions of the world, known for its high forage potential, with little known about ...
The Effect of Land Use and Land Cover Changes on the Livelihoods of Agro-Pastoral Communities in Baidoa District-Bay Region, Somalia

Abdirahman, Mustaf Abdullahi (8/20/2021)

Land use and land cover (LULC) changes have become a focus of global climate science and environmental research since the introduction of ‘Land use and land cover project’ in the early 1990s by the International ...
EVALUATING THE IMPACT OF HUMANITARIAN INTERVENTIONS ON AGRICULTURE PRODUCTIVITY IN SYRIA USING REMOTE SENSING AND MACHINE LEARNING

Sujud, Lara (2/10/2023)

Recently, there has been an increased interest in developing new methods to measure the impact of complex humanitarian interventions in hard-to-reach areas to help guide policy decisions. Quantifying agricultural interventions ...
EVALUATION OF CHIRPS AND GPM-IMERG PRECIPITATION ESTIMATES AGAINST GROUND RAIN GAUGE OBSERVATIONS OVER LEBANON

Sleiman Haidar, Aleel (5/11/2021)

The objective of this paper is to assess two satellite precipitation products, Climate Hazards Center’s Infrared Precipitation with Stations (CHIRPS) and the product of the Global Precipitation Mission; the Integrated ...
EVALUATION OF FAO’S WATER PRODUCTIVITY PORTAL (WAPOR) YIELD OVER THE BEQAA VALLEY, LEBANON

Ajour, Salma (7/8/2021)

With the increasing pressure of agriculture on water and land, achieving high water productivity is essential. Models such as FAO’s Water Productivity Portal (WaPOR) aim to estimate water productivity by providing yield ...
EXPLORING THE POTENTIAL OF BAYESIAN NETWORKS TO PREDICT THE WATER QUALITY OF FRESHWATER SYSTEMS BASED ON LANDSAT-REMOTELY SENSED DATA

El Kerr, Georges (2024-01-24)

Eutrophication is a worldwide environmental problem affecting many freshwater systems that are seeing an increased risks of harmful algal blooms (HABs). Water management agencies are under pressure to monitor these systems ...
Impact of Evapotranspiration and Biomass Model Selection on Irrigation Economics: WaPOR, HSEB, And GYMEE. Insights From the Litani River Basin

Hazimeh, Rim (2023-10-24)

Using Economic Irrigation Water Productivity (EIWP) as an indicator for on-farm irrigation decision-making is of utmost importance in addressing the challenges posed by poor policies in managing agricultural water use, ...
Intercomparison of latent and sensible heat fluxes from eddy covariance and scintillometry over small vineyard in a Semi-arid region

El Chouwani, Jad (9/16/2021)

Accurate measurements of evapotranspiration and of energy fluxes between the land and the atmosphere are very important in understanding climatic patterns. Several techniques and models can measure heat fluxes and ...
Machine Learning Outperforms EEflux METRIC Model on Point Estimates

Hamdar, Yasmine (2/4/2021)

For a vast number of countries, especially in the Mediterranean area, water shortage is among the most important agricultural and environmental hazards. As water consumption rises, the situation worsens due to a deficient ...
Meta-Learning Techniques for Assessing EEflux (METRIC) ET versus Real ET

Awad, Sara (2/4/2021)

Together with the increasing occurrence of drought events in many regions of the world, the constant need to increase agricultural production demands a more cautious regional water resources planning and assessment of ...
