Abstract:

The paper presents an evaluation of climate simulations by the ocean and atmosphere general circulation models from the IPCC DDC for two regions: the Central European area and Poland. The comparisons have concerned air surface temperature, precipi-tation and wind speed. Control runs of the models for the period 1960-1989 and the results of the "Greenhouse Gas plus Sulphate" experiment for the next century 2000-2099 have been analysed. Re-analysed observed data have been used as the reference distributions for climate parameters.

Keywords: climate simulations, general circulation models, air temperature, precipitation, wind

Abstract:

In the first part of the paper various approaches to the formulation of regional climate scenarios are described. In the second part an example of a climate scenario for Poland based on results from the ECHAM1/LSG general circulation transient model is presented. Two perturbed runs of the model are considered: A — "business as usual" and D — "accelerated policies". The hydrological regime of Polish catchments in changed climate conditions is evaluated using the CLIRUN 31 watershed model. Some of the results are discussed.

Keywords: regional climate scenarios, general circulation models, global climate change, downscaling, water balance model, hydrological impact assessment

Abstract:

The paper presents the results of the impact of climate change on water resources in four countries in South Asia. Under present socio-economic and climatic conditions, China, India, Pakistan and South Korea are facing water deficits. The characteristic feature of water management in South Asia is the dominating role of agriculture in water use. The key question addressed in the paper is the impact of climate change on water resources, and the adaptive measures that may be used to cope with water deficits. In all the analyzed countries, the main reason for worsening water conditions is the expected population growth. The effect of climate change is in most cases marginal, independent of the scenario applied. Improved demand management and institutional adaptation are primary components in increasing the robustness of water systems in South Asia under increasing supply uncertainty due to demographic processes and climate change.

Keywords: climate change; irrigation; water resources
