摘要

即使非洲拥有世界上最大的水资源和大河,它们在大陆上分布不均匀,一些国家拥有丰富的水资源,其他国家被迫做出艰难的选择,以获得可持续的水资源;与此同时,降水的状态也具有相同的特征:在一年中的特定时段过多,由于高温导致的高蒸发率,降水减少(或完全消失)。在殖民时期和非洲国家获得独立之后,工程行动和城市规划与这些自然因素重叠,以歧视性的方式影响了对这一重要资源的获取。气候变化使这片大陆上的新移民人口的动态趋势翻了一番,对这片大陆上可能发生的进化产生了负面影响。水的商品化是另一个严重打击非洲穷人的因素;由于非洲城市的富裕地区与城市供水管道和设施连接良好,同一城市的贫困地区完全无法获得供水设施。最贫穷的人必须购买瓶装水来应对日常挑战,他们的大部分收入被用于获得水。本文旨在向东欧读者介绍这个最具活力的大陆将面临的问题和挑战,以及它如何影响那里和世界其他地区因移民而产生的演变。非洲水景观的另一个组成部分是难以获得水,即使有水,其质量也令人怀疑,给个人和国家带来了巨大的医疗后果和成本。

AFRICA’S WATER INSECURITY AND ITS TRIGGERS
Even Africa boasts some of the greatest water resources in the world with large rivers, they are unevenly distributed on the continent, some countries being well endowed with water resources, other being forced to make difficult choices in order to get sustainable access to water; in the same time, precipitations’ regime has the same feature: too much during specific part of the year, lower (or missing altogether) precipitations doubled by high evaporation rate due to high temperatures. Overlapping these natural elements, there have been engineering actions and urban planning – both, during colonial period and after Africa’s countries gained independence – influencing the access to this vital resources in a discriminatory manner. Climate changes doubled with the dynamic population trend on this continent are newcomers, influencing in a negatively way the possible evolution on the continent. Water commodification is another element hitting hard the poor in Africa; as wealthy parts of African cities are well connected to urban water pipes and facilities, poorer parts of the same city totally misses access to water facilities. The poorest people must buy bottled water to get through daily challenges, large part of their incomes being diverted to gaining access to water. The paper intends to bring to East-European audience the problems and challenges the most dynamic continent is going to face, and how can it influence the evolution there, and in other parts of the world, due to migration. Poor access to water, and when available its dubious quality, are other components of African water landscape with great medical consequences and costs at both personal and state level.
