Systems Approach to Link Big Socio-ecological Geo-data to Food Systems Sustainability
Rapid development of multi-dimensionally, multi-scale, timely updated socio-ecological geodata
presents an opportunity as potential information resource for supporting effective decisionmaking
of stakeholders involved with ...
Quantification of Agricultural Water Productivity at Field Scale and Its Implication in On-Farm Water Management
The Kingdom of Saudi Arabia (KSA) is under
extreme water shortage conditions. About 80 % of water in
KSA is utilized by the agricultural sector; therefore, proper
management of irrigation water is required to produce ...
Potentials of Geoinformatics application in mapping NUS species for food and nutritional security
Geo- informatics presents great potential in the context of sustainable Agro-ecosystems development through mapping and monitoring. These include: crop types, corp associations, crop suitability, crop yield, cropping ...
Characterization of spatial variability of soil physicochemical properties and its impact on Rhodes grass productivity
Characterization of soil properties is a key step in understanding the source of spatial
variability in the productivity across agricultural fields. A study on a 16 ha field located in the
eastern region of Saudi Arabia ...
CART and IDC – based classification of irrigated agricultural fields using multi-source satellite data
To understand water productivity of crops cultivated in the Eastern Province
of Saudi Arabia, this study was conducted to generate a reliable crop type
map using a multi-temporal satellite data (ASTER, Landsat-8 and MODIS) ...
Methodology for Assessing and Monitoring Rangeland Vegetation in Central Asia
Rangelands Central Asian countries occupy a total area of approximately 260×106 hm2
, occupying 65% of
the total land area of these five countries (Gintzburger, 2004). These rangelands are considered as the
largest contiguous ...
Quantification of the Terrestrial Phytomass and Carbon in the Mountainous Forest Ecosystem Using Remote Sensing and In-Situ Observations
The aim of this research was to develop an understanding of how mountainous forests function in relation to forest phytomass and
carbon accumulation in the terrestrial vegetation pools which will help develop options for ...
Mapping forests in monsoon Asia with ALOS PALSAR 50-m mosaic images and MODIS imagery in 2010
Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle
and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and
quantify these ...
Restoring the Jordan’s Badia Agro-Ecosystems - tracking developmental interventions and impacts using Remote Sensing
This is a presentation held in Jordan under the Water and Livelihood Initiative (WLI). It is an overview of the Jordan's situational analysis reflecting main problems, solutions and relative tools adopted.
Spectral Reflectance Models for Characterizing Winter Wheat Genotypes
Optimum wheat (Triticum aestivum L.) yield can be achieved by
developing and growing the best genotypes in the most suited
environments. However, exhaustive field measurements are
required to characterize plants with ...
