Characterization of climate impacts on a semi-arid agricultural perimeter in Morocco

نویسندگان

چکیده

The manifestations of climate change in precipitation, air temperature and simulated evapotranspiration for crops the Tadla perimeter central Morocco are examined. study area is characterized by a semi-arid climate, with potential agricultural vocation. This exposed to scarcity water resources crop irrigation. To this effect, it treating rainfall over 60 years (1958-2018) at 27 measuring stations reference evapo-transpiration (ETo) 49 (1969-2018) 4 stations. Following data analysis homogeneity tests on agro-climatic time series (Pettitt test, Lee Heghinian Buishand test Hubert’s segmentation method). It detecting that there breaks annual rainfall, mean respective 1978, 1995 1978. Because these time, reducing 36%, atmospheric warming 1°C demand evaporation coupled plant transpiration increases 13%. Consequently, requirement significantly production.

Impacts of climate change on extreme precipitation events in arid (Bandar Abbas) and semi-arid (Shahrekord) stations in Iran

The aim of this paper is to project extreme precipitation events in an arid and a semiarid station. In order to project climate change based on general circulation models (GCMs), we have applied LARS-WG[1] downscaling tool. This stochastic weather generator down-scaled the climate of two synoptic stations using HADCM3 model and A2 emission scenario for 2040. We extracted extreme precipitation e...

Using the IHACRES model to investigate the impacts of changing climate on streamflow in a semi-arid basin in north-central Iran

Understanding the variations of streamflow of rivers is an important prerequisite for designing hydraulic structures as well as managing surface water resources in basins. An overview of the impact of climate change on the streamflow in the Hablehroud River, the main river of a semi-arid basin in north-central Iran, is provided. Using the LARS-WG statistical downscaling model, the outputs of Ha...

Potassium reserves in soils with arid and semi-arid climate in southern Iran: a perspective based on potassium fixation

ABSTRACT- The present research was conducted to study K forms and fixation in soils of southern Iran (Hormozgan Province) with aridic and aridic-ustic regimes and to address the relations between soil mineralogy and potassium forms. Thirteen surface soil samples (0-25 cm) were collected from different regions and analyzed in laboratory. Illite and feldspar and mica are the major clay and soil m...
