Abstract:
Abstract Severe droughts in southern Africa are associated with livelihood impacts, a strain on local economies, and other hardships. Extensive effort has been spent in the past trying to improve responses to periods of extensive drought. There have also been renewed calls for improvements to climate change adaptation by adopting more proactive governance and disaster risk reduction approaches. Few efforts, however, have been made to assess how to learn more from past drought efforts so as to enhance overall resilience to future drought risks. Few have examined the role and contributions of in

Abstract:
Ecosystem services refer to the direct and indirect benefits to humanity from an ecosystem. The ability to spatially incorporate multiple biophysical environments is crucial to ecosystem services, thus promoting cooperation between science and policy in seeking solutions to global challenges, including drought disasters. Therefore, understanding ecosystem services, for instance, from forest/vegetation in view of contributing to drought disaster risk adaptation is critical to human-nature interactions and proper sustainable conservation thereof. No known study has been done on ecosystem service

Abstract:
Abstract Droughts have severe direct impacts on the livelihoods of rural populations. Thus, the management of water for communal agriculture and water supply should be well coordinated to enhance drought resilience. Notwithstanding the interrelations among water management institutions in South Africa, there are complexities in the way these institutions work together, both in preparation for, and during drought times. In this article, we examine the governance of water resources in South Africa with a view to understanding institutional coordination in drought management at different operatio

Drought limits the production of plantation forests, notably in the drought-prone Zululand region of South Africa. During the last 40 years, the country has faced a series of severe droughts, however that of 2015 stands out as the most extreme and prolonged. The 2015 drought impaired forest productivity and led to widespread tree mortality in this region, but the identification of tree response to drought stress remains uncertain because of its spatial variability. To address this problem, a method that can capture drought patterns and identify trees with similar reactions to drought stress is

In attempting to do this, it became clear that the effects of drought on rural black communities was not a well understood phenomenon.

AbstractClimate change impacts a natural and human system on the entire globe. Climate-related extreme weather such as drought, floods, and heat waves alters the ecosystems that society depends on. Climate, land, energy, and water systems (CLEWS) are a critical aspect of high importance on resource availability, distribution, and interconnection. The nexus provides a set of guidelines to South Africa that aims on creating a level playing field for all sectors while achieving the aims of the SDGs that are cross-sectoral and multilevel approaches to climate change. The nexus expressed three domains that included resources, governance, and security. It integrated a smart climate resilient with inclusion of the governance and involvement of the stakeholders. Recognition of spatial and sector interdependencies should inform policies, investment and institutional for enhancing nexus security and climate change towards making transition green carbon deals. The nexus offers an integrated approach that analyzes the trade-offs and synergies between the different sectors in order to maximize the efficiency of using the resources that adapt institutional and optimum policy arrangements. Economic transformation and creation of employment through green economy is one of the COP26 green deal agendas in curbing the carbon emissions (green house emission, industrial processes, fuel combustion, and fugitive emissions) as mitigation to climate change, which is cost-effective and economically efficient. The future climate change policy in the developing countries is likely to be both promoted by climate technology transfer and public-private cooperation (cross-sector partnership) through the technology mechanism of the nexus and inclusion of the gender.

AbstractThe vulnerability of the climate change in the South of the Mediterranean’s south regions varies depending on the part of their climate which is sensitive to the economy. In Tunisia, agriculture represents 16% of the workforce and 12% of GDP in 2006. In Algeria, agriculture represents 20% of the workforce and 8% of GDP in 2009. In Morocco, agriculture accounts for 40% of the workforce and 17.7% of GDP in 2006. The agriculture is directly related to the availability of water which in turn is directly related to rainfall. The drought has affected all countries of the Maghreb. It is considered the most severe in the history of these countries. The drought has forced the agricultural sector in Morocco to the limitation of annual crops which are not needed, the prohibition of any new tree planting and the ban on vegetable crops in dry years. During the years 1987, 1988, and 1989, Tunisia has experienced the most critical drought. It led to a water deficit of around 30%. For Morocco the rainfall shows a negative trend at national and regional scales, and spring rainfall has declined by over 40% since the 1960s. For Algeria, the western region has recorded a considerable reduction in rainfall. The winter rains have decreased between 40% and 70%. Contributions to dams have decreased between 30% and 50%. These changes had a negative influence on the water resource and crop yield. Many programs have been initiated since then to meet the growing demand.

Abstract:
Surface tension and solution evaporation of aqueous solutions of sodium lauryl sulfate (SLS), ECOSURF™ EH-14, and ECOSURF™ SA-9 under natural convection is examined through experimental methods. SLS is an anionic surfactant while EH-14 and SA-9 are environmentally-friendly nonionic surfactants. Surfactants are known to affect evaporation performance of solutions and are studied in relation to water loss prevention and heat dissipation. Surfactants could be useful under drought conditions which present challenges to water management on a yearly basis in arid areas of the world. Recent water sca

Abstract:
Abstract This paper investigates the techno-economic feasibility of integrating a desalination system to an offshore wind farm. The first part of the paper involves a proposal for the design of a desalination system fitted inside the WindFloat Atlantic hull. Taking into account of the power, footprint, volume and weight requirements of the desalination system, the desalination capacity is chosen to be 10,000 m3/d per platform2. A 3D model of the system is also presented. The second part of the paper focuses on the development of an economic model that gives as output the levelized cost of wate

Abstract:
This technical note is an update to the previous "Water in the Time of Drought: Lessons from Five Droughts Around the World", published in 2018. It explores drought situations and policies in Spain (including the Canary Islands), Chile, Mexico, the dry corridor between Honduras, Guatemala, and El Salvador, Brazil, and South Africa. Each of these countries has recently dealt with droughts and/or developed long-term solutions to manage them. HydroBID, a tool developed by the IDB, will be presented through relevant case studies. After defining drought experiences and institutional frameworks in e
