The study aimed to partition vulnerabilities caused by climate change in suburban districts of Ho Chi Minh City by integrating the use of AHP and GIS. The subjects used data collected from different departments, from surveys in the study area, and consulted with experts in the field of research to assess the weight of factors: Exposure, sensitivity and adaptability. After overlapping component maps, the results showed that the high vulnerability to climate change in five suburban districts of Ho Chi Minh City by 2025 was dominated by Binh Chanh, Nha Be and Hoc. Area of 35,865.57 ha (accounting for 22.84%). The low and medium damage was concentrated in Cu Chi and Can Gio (the respective area was 36,354.33 ha, equivalent to 23.16% and 84,762.27 ha, equivalent to 54%). In addition, the study proposed solutions to increase adaptation and mitigation of the impacts of climate change on the lives of people in the affected area.

Impacts Of Climate Change

The Philippine fisheries sector has been affected by the impacts of climate change. Vulnerability to climate change pertains to a natural system's ability to cope with the negative impacts of climate change, variability, and extremes. Vulnerability Assessment (VA) provides a framework for climate change impacts evaluation over a broad range of systems. Tools such as Fisheries Vulnerability Assessment Tool (Fish Vool) have been developed to do VA. The "giant squid" diamondback (Thysanoteuthis rhombus) fishery in the province of Marinduque is an essential source of food and livelihood in the area. However, its vulnerability to climate change impacts has not been assessed. In this study, the "giant squid" fishery in Gasan, Marinduque, was assessed using Fish Vool. Results revealed that overall climate change vulnerability of the fishery is high, where both sensitivity and adaptive capacity are medium while exposure is high. Overall, the study provided a better understanding of the "giant squid" fishery vis-à-vis climate change and provided information for future fisheries management and conservation in the province.

Insular Ecosystems

Abstract Despite their high vulnerability, insular ecosystems have been largely ignored in climate change assessments, and when they are investigated, studies tend to focus on exposure to threats instead of vulnerability. The present study examines climate change vulnerability of islands, focusing on endemic mammals and by 2050 (RCPs 6.0 and 8.5), using trait-based and quantitative-vulnerability frameworks that take into account exposure, sensitivity, and adaptive capacity. Our results suggest that all islands and archipelagos show a certain level of vulnerability to future climate change, that is typically more important in Pacific Ocean ones. Among the drivers of vulnerability to climate change, exposure was rarely the main one and did not explain the pattern of vulnerability. In addition, endemic mammals with long generation lengths and high dietary specializations are predicted to be the most vulnerable to climate change. Our findings highlight the importance of exploring islands vulnerability to identify the highest climate change impacts and to avoid the extinction of unique biodiversity.

Impacts Of Climate Change

Abstract Ho Chi Minh City (HCMC), the largest city in Vietnam, is steadily growing, certainly towards a mega city in the near future. Like other mega cities at the boom stage, it has to face with serious environmental matters insolvable for many years. The situation may be worse under the effects of global climate change, geological subsidence due to non-standard construction and sea level rise. The situation of HCMC can be damaged or even broken by resonant effects of unsolved environmental matters and latent impacts of climate change. This article shows the challenges to the urban sustainable development under the duo effect of urban environmental matters and climate change in Ho Chi Minh City. Opportunities and strategic directions to overcome the challenges are also analyzed and recommended.

Climate-related variability in rainfall, temperature, and extreme weather (e.g., drought, flood, unseasonal frost) pose significant challenges to working land (i.e., range, forest, and agricultural) managers across the southeastern United States. This document outlines the type of risks that southeastern agriculture and forestry currently face and, in some cases, options to address these risks. Finally, this document looks forward to providing direction on the priority needs of Southeast working land managers and an outline of how the USDA Southeast Climate Hub will address those needs.

Impacts Of Climate Change

Urban forests (i.e. all vegetation present in urban areas), provide environmental and socio-economic benefits to more than half of the global population. Projected climate change threatens these benefits to society. Here, we assess vulnerability to climate change of 16,006 plant species present in the urban forests of 1,010 cities within 93 countries, using three vulnerability metrics: exposure, safety margin and risk. Exposure expresses the magnitude of projected changes in climate in a given area, safety margin measures species' sensitivity to climate change, and risk is the difference between exposure and safety margin. We identified 9,676 (60.5%) and 8,344 (52.1%) species exceeding their current climatic tolerance (i.e. safety margin) for mean annual temperature (MAT) and annual precipitation (AP), respectively. By 2050, 13,479 (84.2%) and 9,960 (62.2%) species are predicted to be at risk from projected changes in MAT and AP, respectively, with risk increasing in cities at lower latitudes. Our results can aid evaluation of the impacts of climate change on urban forests and identify the species most at risk. Considering future climates when selecting species for urban plantings will enhance the long-term societal benefits provided by urban forests, including their contribution to mitigating the magnitude and impacts of climate change.

Vulnerability To Climate Change

Climate change has directly and indirectly affected the livelihood of households that rely on climate conditions for their livelihood in the coastal areas of Vietnam. This study applied the livelihood vulnerability index (LVI) to assess the vulnerability of a household’s livelihood under the effect of climate change in one of the most highly vulnerable areas of Viet Nam - the Can Gio coastal district of Ho Chi Minh city. Based on a survey of 107 households within six communes and one town located in the Can Gio district, the LVI was calculated at both district and commune scales. The results reveal that the district of Can Gio is at a moderate vulnerability level (LVI=0.303), while the Ly Nhon commune (LVI=0.334) is the most vulnerable of the seven surveyed areas. Additionally, the aspects of livelihood strategies (0.516), socio-demographic profile (0.391), and food (0.385) are critical to the determination of the livelihood vulnerability of the seven surveyed communes.

Impacts Of Climate Change

A study was conducted in nine different topographical locations of Kashmir valley to know the perception of the farmers about climate change. Adaptation and mitigation strategies adopted by the farmers were also documented over a specified period viz., 1980-2019. Results from the observed data revealed warming trends in all seasons, however, winter and spring season temperatures have shown statistically significant increasing trends at the rate of 0.040C/year. Analysis of seasonal and annual precipitation data shows a decreasing trend at the rate of -4.5 mm/ year. The farmers in the study areas had perceived that the climate has changed for the last four decades. Increasing temperature, frequent droughts and less snowfall were the main visual parameters experienced by the farmers. About 30-35% of the farmers have adopted different strategies by default to mitigate ill effects of climate change. However, the majority of the farmers (70%) have not adopted any strategy to cope up with the impacts of climate change. Farmers (>90%) have stressed on provision for an early warning system, timely supply of inputs, provision of financial support and nutrients for soil enrichment as viable options to combat the ill effects of climate change.

Impacts Of Climate Change

In a recent World Bank report showed that Viet Nam was one of the five (5) countries that are most affected by sea level rise, a consequence of climate change. Ho Chi Minh City (HCMC), a Vietnam’s biggest city, is accordingly identified as a most area significantly impacted by climate change in the Mekong Delta region. For those countries affected by climate change, future studies on extent and degree of impacts as well as setting out the national strategy and measures adapting to climate change is urgently and a vital of concern. This paper will present surveyed and analyzed results of possible impacts of climate change in Ho Chi Minh City, including: changes of mean temperature over the past 30 years (1979-2008); changes of rainfall (and density) and water level at the Sai Gon River in the period of 1978-2008. In addition, some specific measures for climate change adaptation are also addressed and proposed in the context of Ho Chi Minh City.
