The increase of atmospheric greenhouse gases results in climate changes which cause the rise of sea level and an increased frequency of extreme climatic events including intense storms, heavy rainfall and droughts. There is a lower consensus on the magnitude of changes in climate variables, but several studies show that climate change has an impact on the availability and demand for water resources. Major rivers worldwide have experienced dramatic changes in flow, reducing their natural ability to adjust to and absorb disturbances. Given expected changes in global climate and water needs, this may create serious problems, including loss of native biodiversity and risks to ecosystems and humans from increased flooding or water shortages. This document analyzes the potential impact of climate change on water resources in Romania, Mehedinți County. The work ends with quantitative assessments of the effects of climate change on hydrology for a part of the Mehedinți County basins.

Abstract. Doubtlessly, global climate change and its impacts have caught increasing attention from all sectors of the society world-widely. Among all those affected aspects, hydrological circle has been found rather sensitive to climate change. Climate change, either as the result or as the driving-force, has intensified the uneven distribution of water resources in the Changjiang (Yangtze) River basin, China. In turn, drought and flooding problems have been aggravated which has brought new challenges to current hydraulic works such as dike or reservoirs which were designed and constructed based on the historical hydrological characteristics, yet has been significantly changed due to climate change impact. Thus, it is necessary to consider the climate change impacts in basin planning and water resources management, currently and in the future. To serve such purpose, research has been carried out on climate change impact on water resources (and hydrological circle) in Changjiang River. The paper presents the main findings of the research, including main findings from analysis of historical hydro-meteorological data in Changjiang River, and runoff change trends in the future using temperature and precipitation predictions calculated based on different emission scenarios of the 24 Global Climate Modes (GCMs) which has been used in the 4th IPCC assessment report. In this research, two types of macro-scope statistical and hydrological models were developed to simulate runoff prediction. Concerning the change trends obtained from the historical data and the projection from GCMs results, the trend of changes in water resources impacted by climate change was analyzed for Changjiang River. Uncertainty of using the models and data were as well analyzed.

Agriculture Development

The goal of the article is to work out recommendations aimed at providing sustainability of agriculture development on the level of national economy in conditions of changing climate. The agriculture development within the frames of traditional approach can be studied in two aspects: as a sector subjected to the global climate change impact; as a sector promoting climate change due to greenhouse gas emission. The authors showed that in regard to present trends scientific recommendations aimed at agriculture adaptation to climate changes are the most significant for Russia. On the basis of provided concepts they identified key lines in the said adaptation: to develop innovation connected with adaptation to consequences of climate changes; to upgrade the system of agro-insurance; to use methods of organic food production; to monitor and appraise adaptation of agriculture to climate changes; to introduce strategic planning of sustainable development and location of agricultural production. These lines should be realized on the basis of integrity, strategic orientation and scientific support of agricultural production. These lines can stabilize the level of key parameters of the sector in the long-term perspective.

Climate Change Effects

South Africa is already hydrologically vulnerable and this is likely to be exacerbated by both nonpermanent ENSO-related as well as more permanently greenhouse-gas forced climate changes. Climate change effects are explained by way of the hydrological equation. This serves as a backdrop to a brief review, in a hydrological context, of projected perturbations to temperature, rainfall and potential evaporation, over southern Africa. Methodologies for simulating hydro logical responses to climate change are assessed. These include more direct GCM-derived output, with some emphasis on recent advances in climatic downscaling, and the application of appro priate hydrological models for use in impact studies. Scale problems of importance to hydrologists are highlighted. Directions to which climate change-related hydrological research efforts should be expended in South Africa are summarized, before two case study simulations, one a general sensitivity study of hydrological responses to changes in rainfall over southern Africa, the other a more specific hydrological response study to the El Niño of the 1982-83 season, are presented. The article concludes with a discussion on whether or not water resources practitioners in South Africa should respond to climate change.

Lake Kivu

Climate change is emerging as one of the most miscellaneous expressions of the global change nowadays. It potentially affects ecosystems including water resources. The change of climate also has significant impacts on the availability of water, as well as the quality and quantity of water that is available and accessible. Aiming at studying the effect of climate change on water resources, 25 years collected secondary data of both climatic and hydro-meteorological stations were used and Statistical analysis was performed using ORIGIN PRO 8.0 Software. The study linked the surface elevation of Lake Kivu variation with respect to climate change where the level of the lake matches to pluviometric and anomalies values. Finally, the statistical analysis could not directly link the temperature variation with that of surface water level in the lake. Climate change is real and happening now and surely affects water resources among others making an urgent need to control anthropogenic inputs into the atmosphere, one of the factors forcing climate change.

The damage of coastal ecosystems are no longer dominated by human activity, but the condition of global climate change were also influenced. Climate change impact on the environment influencing the coastal management paradigm. This study emphasizes on how to develop a adaptation strategy of coastal zone management due to the impact of climate change through remote sensing approach, Geographic Information Systems (GIS), and adaptation strategies analysis. Location of research conducted in the Region of Segoro Anakan Bay, District Ngadirojo Pacitan. The results showed the impact of climate change is affecting the area and production of seaweed culture in the form of tectonic conditions aggravated by silting waters. To combat the effects of climate change, the adaptation scenario is implemented to intensification and extensification of land use, alternative livelihoods, minawisata as a combination of all three.

Abstract. Climate change is expected to alter the hydrological cycle resulting in large-scale impacts on water availability. However, future climate change impact assessments are highly uncertain. For the first time, multiple global climate (three) and hydrological models (eight) were used to systematically assess the hydrological response to climate change and project the future state of global water resources. This multi-model ensemble allows us to investigate how the hydrology models contribute to the uncertainty in projected hydrological changes compared to the climate models. Due to their systematic biases, GCM outputs cannot be used directly in hydrological impact studies, so a statistical bias correction has been applied. The results show a large spread in projected changes in water resources within the climate–hydrology modelling chain for some regions. They clearly demonstrate that climate models are not the only source of uncertainty for hydrological change, and that the spread resulting from the choice of the hydrology model is larger than the spread originating from the climate models over many areas. But there are also areas showing a robust change signal, such as at high latitudes and in some midlatitude regions, where the models agree on the sign of projected hydrological changes, indicative of higher confidence in this ensemble mean signal. In many catchments an increase of available water resources is expected but there are some severe decreases in Central and Southern Europe, the Middle East, the Mississippi River basin, southern Africa, southern China and south-eastern Australia.
