“…Rainfall during autumn allows the vegetation to restart evapotranspirating and to reach the same value at the end of the year as in the reference period. These results are in agreement with specific studies like those made with the CERES Wheat model (Eitzinger et al, 2003;Mera et al, 2006). The CERES-wheat model was designed to simulate the effect of crop management on crop growth, development and yield.…”

Abstract. The Meuse is an important rain-fed river in NorthWestern Europe. Nine million people live in its catchment, split over five countries. Projected changes in precipitation and temperature characteristics due to climate change would have a significant impact on the Meuse River and its tributaries. In this study, we focused on the impacts of climate change on the hydrology of two sub-catchments of the Meuse in Belgium, the Lesse and the Vesdre, placing the emphasis on the water-soil-plant continuum in order to highlight the effects of climate change on plant growth, and water uptake on the hydrology of two sub-catchments. These effects were studied using two climate scenarios and a physically based distributed model, which reflects the water-soil-plant continuum. Our results show that the vegetation will evapotranspirate between 10 and 17 % less at the end of the century because of water scarcity in summer, even if the root development is better under climate change conditions. In the low scenario, the mean minimal 7 days discharge value could decrease between 19 and 24 % for a two year return period, and between 20 and 35 % for a fifty year return period. It will lead to rare but severe drought in rivers, with potentially huge consequences on water quality.

“…The DSSAT model comprises the CERES-Wheat (Crop Environment Resource Synthesis-Maize and Wheat) model for simulating the growth and yield of wheat as a function of the soil-plant-atmosphere dynamics, and it has been used for many applications such as regional assessments of the impact of climate variability and climate change and energy crops production [24,30].…”

Bioenergy crops are expected to play an important role in reducing greenhouse gas (GHG) emissions and in enhancing the security of energy supply. According to Sir David King, climate change is our most serious threat. This paper presents some new evidence on the way in which changes to the climate will affect winter wheat yield in Norfolk, England, and there are some surprising but vitally important outcomes. Winter wheat shows different dependence on climate parameters when the temperature is increased, rainfall increased or decreased, and carbon dioxide (CO2) levels increased. Model predictions showed that under many future climate scenarios winter wheat yield would increase with decrease in precipitation and in temperature ranging from +1.

RESUMOA pecuária leiteira é uma atividade de grande importância no nordeste brasileiro, podendo ser afetada de forma direta e indireta, caso as atuais previsões climáticas sejam confirmadas até o final do século. O objetivo deste trabalho foi estimar os impactos das mudanças climáticas sobre a produção leiteira nos estados de Alagoas, Bahia e Sergipe. Os valores do índice de temperatura e umidade (ITU), do declínio da produção de leite (DPL) e da redução do consumo alimentar (RCA) de vacas leiteiras foram calculados para os cenários climáticos B1 e A1F1 do IPCC. Utilizou-se um modelo multiplicativo para estimar o efeito das alterações de temperatura sobre os valores normais da umidade relativa do ar. Com base em ambos os cenários do IPCC, as regiões produtoras, situadas no norte e litoral do estado da Bahia e áreas litorâneas dos estados de Alagoas e Sergipe, serão afetadas expressivamente em decorrência do aumento do estresse térmico, com reduções marcantes na produção de leite e no consumo alimentar, especialmente de animais com alto potencial genético de produção. Este cenário pode afetar as atuais regiões produtoras dos estados nordestinos, de forma que a exploração leiteira seja limitada aos animais com baixo desempenho produtivo.Palavras-chave: conforto térmico, gado leiteiro, ITU, risco climático, SIG Climate change scenarios and their impacts on milk production in northeastern states of Brazil ABSTRACTMilk production is an activity of great importance in the Brazilian context, and it may be directly and indirectly affected if current climate predictions are confirmed until the end of this century. The objective of this work was to estimate climate change impacts on milk production in the states of Alagoas, Bahia and Sergipe. Values of the temperature humidity index (THI), decline in milk production (DMP) and decline in feed intake (DFI) of dairy cows were calculated for the B1 and A1F1 climate scenarios, described by the IPCC. A multiplicative model was used to estimate the effect of temperature change on the normal values of relative humidity. Based on both IPCC scenarios, production regions, located in the north and coast of the Bahia state and coastal areas of the states of Alagoas and Sergipe, will be adversely affected due to thermal stress, with profound reduction in milk production and feed intake, especially in case of animals with high genetic production potential. This scenario may affect the current producing in the northeastern states of Brazil, in such a way that milk production be limited only to animals with low productive performance.
