Abstract In order to achieve worldwide food security, there is a focus on sustainable intensification of crop production. This requires irrigation water use for irrigated croplands, as withdrawals are already resulting in groundwater exploitation and unmet ecosystem requirements. Our study aims quantify attainable wheat, maize, rice soybean production currently cropland under use. Attainable ac...
This article summarizes the state-of-the-art knowledge gained from field observations and laboratory studies regarding foam as a liquid controlling agent in porous media. Being least explored property of foam, its effect potential have often been overlooked or simply ignored. The aim with this review is therefore to demonstrate abilities that could block, reduce, delay, suppress, divert water f...
Municipal supply of water under climate variations, growing population, uncertainty, and scarcity, requires planners to devise feasible sustainable sourcing plans; especially for territories relying on groundwater. The conventional ways cope with scarcity will no longer guarantee reaping the maximum benefits declining available resources. Efficiency circularity are claimed as essential criteria...

Episodic recharge as a result of infrequent, high intensity precipitation events comprises the bulk of groundwater recharge in arid environments. Climate change and shifts in precipitation intensity will affect groundwater continuity, thus altering groundwater recharge. This study aims to identify changes in the ratio of groundwater recharge and precipitation, the R:P ratio, in the arid southwe...
Radium isotopes (Ra, Ra, Ra, and Ra) and water chemistry were used to identify two chemically distinct sources of submarine groundwater discharge (SGD) in Celestún Lagoon, Yucatán, Mexico. Low salinity groundwater discharging from springs within the lagoon has previously been identified and extensively sampled for nutrient concentrations. However, a second type of groundwater discharging into t...
Soil hydrological processes play an important role in land-atmosphere system. In most climate models, these processes are described by soil moisture variations in the first 2 m of soil resulting from precipitation, evaporation, and transpiration. Groundwater effects on soil moisture variations and surface evaporation are either neglected or not explicitly treated. Although groundwater may have ...
This paper aims to present and briefly discuss policy documents focusing on the internationalisation of higher education in Malaysia their implication international student withdrawals. Numerous policies guidelines have been developed by Ministry Higher Education propel as hub this region. However, current statistic does not seem support national goal increase enrolment 200,000 2020 or be an ex...
