“…The statistics evaluation associated with the average error between observed and simulated values of the six plots presents RMSE and BIAS values of 3.45 t ha -1 and -7.34, respectively. These results are analogous to those indicated by Pereira et al (2008) in Brazil (Itararé IAC-5986 cultivar), Medany (2006) Valour cultivar, Abdrabbo et al (2010) in Egypt (Valour and Desiree cultivar), and Daccache et al (2011) in England's humid climate (Bintje cultivar). For this author, the differences expressed as a percentage between the simulated and observed mean yields were very small (1 to 3%).…”

“…The rainfed production is very unstable, which is confirmed by the positive results of field experiments with irrigated crops carried out all over the world in different climatic zones (arid, Mediterranean, temperate). These results show how the shortages of rainfall and dry periods have a significant effect on yielding of different kinds of crops (Erdem et al 2006;Holden and Brereton 2006;Żarski 2009;Dmowski et al 2010;Dowgert 2010;Van der Velde et al 2010;Daccache et al 2011;Podleśny and Podleśna 2011;Żarski et al 2011, 2013aShirazi et al 2014). Bindi (2002, 2005) discussed the relationship between agricultural production and the characteristics of climate in Europe.…”

Climate change scenarios suggest that long periods without rainfall will occur in the future often causing instability of the agricultural products market. Th e aim of the research was to build a model describing the amount of precipitation and droughts for forecasting crop yields in the future. In this study, the authors analysed a non-standard mixture of gamma and one point distributions as the model of rainfall. On the basis of the rainfall data, one can estimate the parameters of the distribution. Th e parameter estimators were constructed using the method of the maximum likelihood. Th e obtained rainfall data allow confi rming the hypothesis of the adequacy of the proposed rainfall models. Long series of droughts allow one to determine the probabilities of adverse phenomena in agriculture. Based on the model, the yields of barley in the years 2030 and 2050 were forecasted which can be used for the assessment of other crops productivity. Th e results obtained with this approach can be used to predict decreases in agricultural production caused by the prospective rainfall shortages. Th is will enable decision makers to shape eff ective agricultural policies in order to learn how to balance the food supplies and demands through an appropriate management of the stored raw food materials and the import/export policies.

“…Outdoor rainfed and irrigated crops are particularly sensitive, both directly from changes in rainfall and temperature and also indirectly, as any change in climate will also impact on the agricultural potential of soils by modifying soil water balances and changing land suitability for production (Daccache et al, 2012). These changes will in turn affect the availability of water to plants and impact on other land management practices (e.g., trafficability for seedbed preparation, spraying, and harvesting) including the demand for irrigation (Daccache et al, 2011). In regions where rainfed agriculture is dominant, changes in the timing, distribution, and reliability of rainfall may force a gradual switch to irrigated production, to maintain crop yields.…”
