Statistical Research Issues in Crop and Cropping System Experiments for Enhancing Food Security Support
Food security is essential to maintain the human population and the environment. The strategies for food security must take into consideration the human population dynamics and dynamics of natural resources, plant and ...
Growing More Olives with Less Water
Despite the importance of olive
production in Morocco and Syria,
the absence of modern production
methods such as irrigation prevent
the sector from reaching its full
potential. Although widespread
water-scarcity in North ...
Performances, Policies, Challenges and Opportunities of the Tunisian Agriculture Sector from Natural Resources Management Perspective a SWOT Analysis
A comprehensive assessment of the Tunisian agricultural potential, production, natural resources
management and policies has been presented using SWOT (strengths, weaknesses, opportunities and threats)
analysis. Concerning ...
A Participatory GIS Approach to Identify Critical Land Degradation Areas and Prioritize Soil Conservation for Mountainous Olive Groves (Case Study)
Climate change scenarios predict an
increase in the frequency of heavy rainfall events in
some areas. This will increase runoff and soil erosion,
and reduce agricultural productivity, particularly on
vulnerable mountainous ...
Developing scenarios to assess sunflower and soybean yield under different sowing dates and water regimes in the Bekaa valley (Lebanon): Simulations with Aquacrop
In a semi-arid environment, the main challenge for crop production is water
limitation in space and in time. Considered as appropriate tools, models are used to
evaluate the effects of water deficit on crop productivity ...
Geostatistical monitoring of soil salinity in Uzbekistan by repeated EMI surveys
Soil salinization in the lower reaches of Amudarya is a constant threat. High seepage losses in irrigation water delivery
network and deteriorated drainage network result in rising groundwater tables. The shallowgroundwater
table ...
Economic analysis and environmental impacts of water harvesting techniques in the low rainfall areas of Jordan
Water harvesting has become an important priority for supporting
the increasing population in the low rainfall areas of Jordan. The specific
objectives of this paper are to assess the economic and environmental impacts
of ...
Flume experimental evaluation of the effect of rill flow path tortuosity on rill roughness based on the Manning–Strickler equatio
Numerous soil erosion models compute concentrated flow hydraulics based on the Manning–Strickler equation
(v = kSt R2/3 I1/2) even though the range of the application on rill flow is unclear. Unconfined rill morphologies
generate ...
The Generalized Difference Vegetation Index (GDVI) for Dryland Characterization
A large number of vegetation indices have been developed and widely applied
in terrestrial ecosystem research in the recent decades. However, a certain limitation was
observed while applying these indices in research in ...
Economics of salt-induced land degradation and restoration
Food security concerns and the scarcity of new productive land have put productivity enhancement of degraded lands back
on the political agenda. In such a context, salt-affected lands are a valuable resource that cannot ...
