<p>The presentation will summarize the main findings of the chapter “Water”[1] of the report “Climate and Environmental Change in the Mediterranean Basin – Current Situation and Risks for the Future”. This report was published in November 2020 and prepared by 190 scientists from 25 countries, who belong to the scientific network “Mediterranean Experts on Climate and Environmental Change”.</p><p>Water resources in the Mediterranean are scarce, unevenly distributed and often mismatching human and environmental needs. Approx. 180 million people in the southern and eastern Mediterranean countries suffer from water scarcity (<1000 m<sup>3</sup> capita<sup>-1</sup> yr<sup>-1</sup>). The main water use is for agriculture, and more specifically on the southern and eastern rim. Water demand for both tourism and agriculture peak in summer, potentially enhancing conflicts in the future. Municipal water use is particularly constrained in the south and will likely be exacerbated in the future by demographic and migration phenomena. Northern countries face additional risks in flood prone areas where urban settlements are rapidly increasing.</p><p>Climate change, in combination with demographic and socio-economic developments, has mainly negative consequences for the water cycle in the Mediterranean Basin, including reduced runoff and groundwater recharge, increased crop water requirements, increased conflicts among users, and increased risk of overexploitation and degradation. These impacts will be particularly severe for global warming higher than 2°C.</p><p>Adequate water supply and demand management offers some options to cope with risks. Technical solutions are available for improving water use efficiency and productivity, and increasing reuse. Seawater desalination is increasingly used as adaptation measure to reduce (potable) water scarcity in dry Mediterranean countries, despite known drawbacks in terms of environmental impacts and energy requirements. Promising solar technologies are under development, potentially reducing emissions and costs. Reuse of wastewater is a solution for agriculture and industrial activities but also recharge of aquifers. Inter-basin transfers may lead to controversies and conflicts. Construction of dams contributes to the reduction of water and energy scarcities, but with trade-offs in terms of social and environmental impacts.</p><p>Overall, water demand management, which increases water use efficiency and reduces water losses, is crucial for water governance for a sustainable development. Maintaining Mediterranean diet or coming back to it on the basis of locally produced foods and reducing food wastes may save water but also carbon emissions while having nutritional and health benefits.</p><div><br><div> <p>[1] <strong>Fader M.</strong>, Giupponi C., Burak S., Dakhlaoui H., Koutroulis A., Lange M.A., Llasat M.C., Pulido-Velazquez D., Sanz-Cobeña A.

The life and livelihood of coastal farming communities in Bangladesh are highly vulnerable to climate and environmental change. Diversification of farmers’ income sources beyond agriculture can be an effective way to cope with the adverse impacts of environmental change. The purpose of this study is to analyse the options and determinants of livelihood diversification (LD) strategies adopted by farmers in the coastal region of Bangladesh. Multiple linear regression technique along with Simpson index, Herfindahl index and priority index have been used for the analysis. Simple random sampling and multistage sampling have been used to select the sample and the study area, respectively. The magnitude of farming household diversification is at medium level. A significant share of annual income comes primarily from fish and rice production, domestic bird rearing and working as agricultural labour. The adoption of diversified activities is strongly influenced by age and education of household head, number of earning family members, social network and government donation. The frequent occurrence of natural disasters, inadequate infrastructure and lack of financial capacity are the critical constraints to LD.
