Soil water in the coastal zones is more vulnerable to salinization. Soil-water vulnerability assessment is an effective tool for soil-water management. This study used the DRASTIC model, which is based on seven factors viz: Depth to soil water, recharge, soil-water bearing layer, soil media, topography, impact of root zone, and hydraulic conductivity to evaluate soil-water salinization potentiality of Ben Tre province.

Mangrove forests are intertidal wetlands and found along tropical, subtropical, and warm-temperate coastlines. They have vital functions in preventing coastal erosion, mitigating effects of wave actions, and protecting coastal habitats. However, mangrove forests are more likely to be vulnerable as typhoons frequently hit and under driving human pressures.

Climate aridization and increased anthropogenic pressure pose a severe threat to natural vegetation, including coastal plant communities. Those located in river basins of the desert zone of Central Asia are among the most vulnerable. Of the variety of ecosystems of the Ili-Balkhash region of Kazakhstan, forests dominated by a rare relict species Populus pruinosa Schrenk are of particular concern. This species occupies a very narrow ecological niche associated with river banks of the arid zone, which makes it very vulnerable to adverse natural and anthropogenic factors.

Mục đích nghiên cứu là để đánh giá sự tổn thương của bờ biển tỉnh Bến Tre bằng chỉ số dễ bị tổn thương (Coastal Vulnerability Index - CVI). Chỉ số CVI được tính dựa trên các đặc điểm địa chất (địa mạo, độ dốc, và tốc độ xói lở của đường bờ) và vật lý (chiều cao sóng, biên độ dao động triều, và mực nước biển dâng) của đường bờ. Kết quả xác định được diễn biến và mức độ tổn thương ở khu vực nghiên cứu.

Vùng biển tỉnh Phú Yên có hình thái địa hình địa mạo với nhiều đầm, vịnh, bãi cát xen với mũi đá nhô sát ra biển và khá nhạy cảm với những tác động của các yếu tố ngoại sinh và nội sinh của biến đổi khí hậu như mực nước biển dâng. Do đó, chỉ số mức độ dễ bị tổn thương bờ biển (Coastal Vulnerability Index) được áp dụng để đánh giá khả năng tổn thương bờ biển tỉnh Phú Yên, trong hai trường gió mùa điển hình Đông Bắc và Tây Nam góp phần vào công tác quản lý tổng hợp đới bờ.

With the rising sea level becoming a more pressing issue to coastal areas, a comprehensive analysis has been conducted to assess the vulnerability of the Çukurova Delta under the projected inundation by the end of the century. The level of inundation was estimated from a multimission satellite altimetry sea level anomaly and significant wave height data between September 1992 and February 2012.

In recent decades, unsustainable use of resources and the implementation of dams upstream accompanied with sea level rise acceleration has led to an extreme mangrove depletion, increase of coastal vulnerability in the Mekong delta. Extensive shrimp culture, where mangrove forest have been turned into aquaculture ponds are adding to the problem. The aim was to assess the current situation and find solutions which go in hand with the Building with Nature (BwN) concept for two selected locations along the Vinh Chau coast.

Droughts can result in heavy crop and livestock losses, in which the poor are usually disproportionately hurt. Poor livestock owners tend to engage in distress sales of livestock at depressed prices, leaving them extremely vulnerable to drought and other shocks in future, and possibly trapping them permanently in chronic poverty. Recurrent droughts in Sub-Saharan Africa over the last two decades have had devastating effects on natural resources and on livelihoods.
