  abstract = {{T}his paper presents a technique for the mapping of soil moisture and irrigation, at the scale of agricultural fields, based on the synergistic interpretation of multi-temporal optical and {S}ynthetic {A}perture {R}adar ({SAR}) data ({S}entinel-2 and {S}entinel-1). {T}he {K}airouan plain, a semi-arid region in central {T}unisia ({N}orth {A}frica), was selected as a test area for this study. {F}irstly, an algorithm for the direct inversion of the {W}ater {C}loud {M}odel ({WCM}) was developed for the spatialization of the soil water content between 2015 and 2017. {T}he soil moisture retrieved from these observations was first validated using ground measurements, recorded over 20 reference fields of cereal crops. {A} second method, based on the use of neural networks, was also used to confirm the initial validation. {T}he results reported here show that the soil moisture products retrieved from remotely sensed data are accurate, with a {R}oot {M}ean {S}quare {E}rror ({RMSE}) of less than 5% between the two moisture products. {I}n addition, the analysis of soil moisture and {N}ormalized {D}ifference {V}egetation {I}ndex ({NDVI}) products over cultivated fields, as a function of time, led to the classification of irrigated and rainfed areas on the {K}airouan plain, and to the production of irrigation maps at the scale of individual fields. {T}his classification is based on a decision tree approach, using a combination of various statistical indices of soil moisture and {NDVI} time series. {T}he resulting irrigation maps were validated using reference fields within the study site. {T}he best results were obtained with classifications based on soil moisture indices only, with an accuracy of 77%.},
