Climate change has resulted in increased vulnerability of smallholder farmers in marginal areas of Zimbabwe where there is limited capacity to adapt to changing climate. One approach that has been used to adapt to changing climate is in-field water harvesting for improved crop yields in the semi- arid regions of Zimbabwe. This review analyses the history of soil and water conservation in Zimbab...

In this paper, we consider a MIMO networked control system with an energy harvesting sensor, where an unstable MIMO dynamic system is connected to a controller via a MIMO fading channel. We focus on the energy harvesting and MIMO precoding design at the sensor so as to stabilize the unstable MIMO dynamic plant subject to the energy availability constraint at the sensor. Using the Lyapunov optim...

Atmospheric water harvesting (AWH) has been an appealing prospect for decades to overcome scarcity in remote areas. Adsorption-based AWH technologies have gained popularity due their adaptability, and applicability using low-grade heat sources. This study presents up-to-date future possibilities of adsorbents systems adsorption-based AWH. In this review, in-depth advancements adsorbent material...

With water becoming an even scarcer resource, rainwater harvesting (RWH) systems are becoming increasingly more commonplace as mechanisms to capture and store rainwater for both agricultural and domestic use. Three important engineering considerations associated with the construction of RWH systems are the capture surface area, the tank volume required for specific demand levels, and the number...

water and energy are key commodities utilized in the process industries.water minimization and energy minimization have been studied separately. in this paper, a new systematic design methodology has been developed for the simultaneous management of energy and water systems that also feature maximum re-use of water. in addition to allowing re-use of water, issues about heat losses inside unit o...
