To evaluation yields productions of different crops to real ecological and socio-economic conditions, in the framework of Land Suitability data production at National, Regional or District level, Gismap has developed an original tool aimed to apply General Land Evaluation methodological framework (as defined by FAO) to real ecological and socio-economic condition of selected study areas and to evaluate potential yields of different crops. The output is a set of combined values of real yield production (t/ha) and potential yield production (0 – 100 %), in a specified site and in a specified time, at large scale.
The approach used for the development of Gismap – AES is described here
Defining crop response to water, calculation crop water requirement and analysis of irrigation schemes is a crucial part of decision-making for agricultural water management
Gismap carry out analysis of
water use efficiency to simulate yield response to water of herbaceous crops in water stress conditions as a result from insufficient soil water content during the growing season;
crop water requirement calculation,
irrigation schemes survey for the qualitative assessment of required rehabilitation interventions with collection data from remote sensing and quantitative by field survey , maps elaboration and arrangement into a DataBase
Gismap work at district or basin level with application of FAO approach defined in “Guidelines for Land Evaluation, mostly for Rain-fed and Irrigated agriculture” for evaluating the real yield production (0-100%) of a given type of land for a defined use, considered in its present condition or after improvements for a defined land use for specific crops. The output data classify the land in a 5 main different classes
Scenarios about yield production of a territory for a specific crop will be designed considering the variation of climatic data in a framework of climate change, the change of different soils productivity, the change of water availability in the contest of desertification phenomena and the change in input levels.
