ABSTRACT: Today satellite system
provides a main instrument supplying regular data on land inventory and
monitoring of land use/land cover changes, in a timely manner. These data are
keys to many applications in different sectors: environment, forestry,
hydrology, irrigation, agriculture, geology, resource management and planning.
Using Landsat image and change detection, this paper presents a method to
extract changes of agricultural land, as the basis for the assessment and
development of irrigation systems, which enhance production and protect land
resources. During the period 1996-2014, the agricultural land in Binh Thuan
decreased from 43.5% (in 1996) to 40.1% (February, 2014) of the total land
surface in the province. However, the land area under cultivation tends to
decrease rapidly, from 25.7% in 1996 to 14.0% in 2014. Combining the results of
land use change and assessing the capacity of the irrigation systems show which
areas are frequently irrigated versus those are not. This allows proposing
irrigation development needs contributing to more production while protecting
land resources.
