Impacts Of Climate Change

Abstract The impacts of climate change on society are becoming increasingly evident. The water sector is sensitive to variations in climatic patterns as it is expected that major changes in flows will occur, along with increased risks of water quality degradation and flooding. According to published climate scenarios the Mediterranean area will become dryer. As a leading group operating in the water sector in Portugal, AdP decided to develop a strategic plan for climate change adaptation with the aim of establishing a strategy for reducing business vulnerability and increasing systems resilience. In developing the plan, a pragmatic method was adopted for characterizing current vulnerabilities. This was founded on the bottom-up approach and supported with past events data, including evaluating their impacts, and the adaptive capacity of systems and utilities to climate extremes. In water supply, the effects of more severe and frequent extreme events are being felt with respect to water quality and availability, representing as much as 80% of the events studied, whereas, in terms of sanitation, floods account for about 90% of events identified. Globally, 78% and 21% of the measures adopted in water supply and wastewater management, respectively, were effective.

Impacts Of Climate Change

Climate change induced by greenhouse gas emissions is expected to alter the natural availability of water, affecting domestic, agricultural and industrial uses. This work aims at assessing the possible future impacts of climate change on precipitation, temperature and runoff, and to simulate the effects on reservoir demand–performance curves. To this aim, a modeling chain is set up, based on the combined use of regional climate models (RCMs) and water supply system simulation models. The methodology is applied to the Pozzillo reservoir, located in Sicily (Italy), which has experienced several droughts in the past. We use an RCM model that, based on a previous study, has proved to be the most reliable in the area, among those of the EURO-CORDEX initiative. RCM precipitation and temperature monthly time series are used to generate future reservoir inflow data, according to two representative concentration pathways, RCP4.5 (intermediate emissions scenario) and RCP8.5 (high emissions scenario) and a two-step bias correction procedure. Simulation of the reservoir indicated that, due to reservoir inflow reduction induced by climate change, performances of the Pozzillo reservoir are predicted to decrease significantly in the future, with impacts of RCP8.5 generally higher than RCP4.5.

Impacts Of Climate Change

As zonas áridas e semiáridas em todo mundo têm expressivos rebanhos de grandes e pequenos ruminantes, que fazem parte de importantes sistemas de produção e da geração de renda das populações. As mudanças climáticas estão atingindo a pecuária destas regiões e, consequentemente, suas produções estão sendo afetadas significativamente, por problemas de baixa oferta hídrica, queda na produção e disponibilidade de forragens, bem-estar animal, causadas por alterações da temperatura, radiação solar, evapotranspiração, baixa pluviosidade e umidade do solo. Este desafio está posto e só poderá ser superado com um esforço conjunto de várias instituições, envolvendo governos, organizações e instituições de pesquisas, que possam aportar recursos, conhecimentos, ferramentas e tecnologias capazes de proporcionar a sustentabilidade ambiental e econômica da atividade pecuária. Este artigo aborda alguns aspectos relacionados aos efeitos das mudanças climáticas sobre os recursos hídricos e as consequências sobre a produção animal. Descreve algumas ferramentas de zoneamento bioclimático e de monitoramento de risco pecuário, além de trazer algumas possíveis alternativas de mitigação aos efeitos das mudanças climáticas, particularmente, relacionadas a diminuição da oferta hídrica para os sistemas de produção de ruminantes, no semiárido. Arid and semi-arid areas in the world has significant herds of large and small ruminants, which are part of major production systems and the generation of income populations. Climate change is affecting the livestock of these regions and, consequently, their productions are being significantly affected by low water supply problems, decrease in the production and availability of feed, animal welfare, caused by changes in temperature, solar radiation, evapotranspiration, low rainfall and soil moisture. This challenge is set and can only be overcome by a joint effort of various institutions, involving governments, organizations and research institutions that can provide resources, knowledge, tools and technologies that provide environmental and economic sustainability of the livestock activity. This article discusses some aspects related to the effects of climate change on water resources and the consequences on animal production. Describes some tools of zones bioclimatic and livestock risk monitoring, and bring some possible alternatives to mitigate the effects of climate change, particularly related to decreased water supply to the ruminant production systems in semi-arid. Keyworlds: water, increase temperature, animal welfare, ruminants, production system.

This Special Issue of the journal Water, “The Evaluation of Hydrologic Response to Climate Change”, is intended to explore the various impacts of climate change on hydrology. Using a selection of approaches, including field observations and hydrological modeling; investigations, including changing habitats and influences on organisms; modeling of water supply and impacts on landscapes; and the response of varying components of the hydrological cycle, the Issue has published nine articles from multi-institution, often multicountry collaborations that assess these changes in locations around the world, including China, Korea, Russia, Pakistan, Cambodia, United Kingdom, and Brazil.

Impacts Of Climate Change

About 7.9 % of population is living in poverty at District 8, which is one of the most vulnerable areas to climate change in Ho Chi Minh City (HCMC). The impacts of climate change (CC) on some related socio-economic parameters at District 8 were assessed using analytic hierarchy process (AHP) and livelihood vulnerability index (LVI). For this, four Asian Development Bank’s criteria including public health, transport, energy, and water supply and drainage (WSD) were used. In addition, however, six World Bank’s criteria including land use, population, gross domestic product (GDP), urban expansion, agriculture and wetland were also used just for initially trying whether or to what extent they can be useful for such downscaled application. Results of this study show that the level of CC impacts on the residential areas is rather high, with an average LVI of 0.056. In addition, the results of AHP shown that the impact levels on the study fields are determined to follow a decreasing order as: first level group including energy, water supply and drainage, transport, and public health (with total score 0.22); the second level group including land use and wetland (with total score 0.14); the third level group including population and urban expansion (with total score 0.1); and at last the fourth level group including GDP and agriculture (with total score 0.09).
