Role of geoinformatics in ensuing global food security with special reference to dryland agroecosystems
Agriculture plays an important role in providing
food security in developing countries. Better agricultural
information is one of the key factors in understanding current
trends and status that determine food security from ...
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 ...
Assessing Agricultural Water Productivity in Desert Farming System of Saudi Arabia
The primary objective of this study was to assess the water productivity (WP) of the annual (wheat, barley, and corn) and biennial (alfalfa and Rhodes grass) crops cultivated under centerpivot irrigation located over desert ...
Monitoring water use in agricultural fields of Saudi Arabia
With growing population, urbanization and irrigated agriculture, water shortages are increasing in arid
regions. In 2012, freshwater consumption for the agricultural sector in Saudi Arabia was estimated at
86%. Accurate ...
Food security in changing Arab environment
The Arab region has the largest food deficit in the world, due to the strained natural resource base and vulnerabilities to climate change implications, which put tremendous pressure on achieving food security. During the ...
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) ...
BigData and ICT for pest surveillance and risk mapping
The date palm is prone to several pests and diseases under changing climate coupled with inadequate and/or lack of proper management,cultural practices and early detection. Red Palm Weevil (RPW) is the most devastating ...
