policies and progressive plans, maintaining and improving the capacity of agricultural lands with higher potential in order to support a growing population is
paramount.
Moreover, conserving and rehabilitating natural resources of lower-potential
lands in order to maintain sustainable man/land ratios is also necessary. Farmers
should be educated in terms of awareness of their regions and the land conditions and
should be awarded if they grow the appropriate crop type.
In order to ensure the sustainability of the innovation of the decision support
system, satellite images are taken every year, determination of yield through parcels
is carried out, and infrastructure is maintained to affirm agricultural support for all
agricultural areas.
Therefore, Turkey has initiated a new era in which decisions are taken through the
spatial infrastructure and planning is carried out accordingly.
13.2 Parcel-Based Support Payment System
A parcel-based support payment system was preferred in the transition period of
passing to an integrated administration and control system. Thus, the aim was to
ensure that the given support was determined most appropriately. For this purpose,
agricultural parcels are digitized to cover farmland at the national level. Then, a yield
model was developed to provide the most accurate support for the parcel-based
support payments for each parcel.
The following steps have maintained the parcel-based support payment system:
(a) Digitization of Agricultural Parcels.
In the scope of the agricultural parcel database work item, all agricultural parcels
within the cadastral parcels and the parcels used for agricultural purposes, as well as
raw soils, were digitized according to satellite images and orthophotos. All usages
were defined, and all nonagricultural usages were separated.
After the digitization process, a parcel-based crop production yield model was
created. In the model, the following steps were carried out:
(b) Creation of Province-Based Yield Maps.
In order to create the province-based yield maps, all constant parameters were
defined, and a weighted overlay method was applied. In the study, the following data
were selected as constant input parameters:
– Digital elevation model (DEM).
– A slope map which was generated from the DEM.
– Soil groups maps.
– Land use capability classes maps.
– Soil depth maps.
