Floods are considered one of the world’s most overwhelming hydro meteorological disasters, which cause tremendous environmental and socioeconomic damages in a developing country such as Pakistan. In this study, we use a Geographic information system (GIS)-based multi-criteria approach to access detailed flood vulnerability in the District Shangla by incorporating the physical, socioeconomic vulnerabilities, and coping capacity. In the first step, 21 essential criteria were chosen under three vulnerability components. To support the analytical hierarchy process (AHP), the used criteria were transformed, weighted, and standardized into spatial thematic layers. Then a weighted overlay technique was used to build an individual map of vulnerability components. Finally, the integrated vulnerability map has been generated from the individual maps and spatial dimensions of vulnerability levels have been identified successfully. The results demonstrated that 25% of the western-middle area to the northern part of the study area comprises high to very high vulnerability because of the proximity to waterways, high precipitation, elevation, and other socioeconomic factors. Although, by integrating the coping capacity, the western-central and northern parts of the study area comprising from high to very high vulnerability. The coping capacities of the central and eastern areas are higher as compared to the northern and southern parts of the study area because of the numerous flood shelters and health complexes. A qualitative approach from the field validated the results of this study. This study’s outcomes would help disaster managers, decision makers, and local administration to quantify the spatial vulnerability of flood and establish successful mitigation plans and strategies for flood risk assessment in the study area.

Saudi Arabia (SA) faces a water shortage, and it further challenges sustainable agriculture, industrial development and the well-being of people. SA uses more than 80% of its water resources for agricultural purposes. Groundwater extractions account for most of this demand, which is not sustainable. Hence, this study aims to analyze water management practices used in SA to propose viable and workable solutions to achieve sustainable management of scarce water resources. This study is based on a critical evaluation of information available on the water sector in SA. About 89% of the water demand in the Kingdom is non-sustainably met through over-pumping from groundwater resources and 9.3% by energy-intensive desalination. SA invested in dams and developed rainwater harvesting to enhance surface water availability and increase the recharge capacity of renewable aquifers. As there is a huge demand–supply gap, water demand management tools are the viable solutions leading to sustainability compared to supply enhancement that is capital intensive. A national agricultural policy, together with a water policy, can make agricultural systems more input efficient with higher productivity. Region-specific sustainable water resources management plans need to be implemented to match the demand–supply gap. Conjunctive water uses utilizing and prioritizing different water sources viz. harvested rainwater, treated wastewater, desalinized water, and groundwater, is vital in sustainable water resources management. In addition, climate change has exerted pressure on the available water resources and water uses as well as users, leading to adaptation for measures that are more sustainable in terms of water management. The most pressing problem SA faces in water resources management is the depletion and degradation of surface and subsurface water sources. SA has to implement many technological and legislative changes in addition to service management, conservation measures, paying a reasonable and justifiable price for water, and strengthening state agencies that will make water resources management in SA sustainable.
