    Climate change has caused pressure on water resources in Jordan. This was accompanied by the Syrian refugee crisis during the period 2009 to 2019. This descriptive study was conducted in the University of Debrecen, during the years 2020 and 2021 within the course of sustainable land use by collecting official statistical data from reliable sources in Jordan on the production of tomato, pepper, and paprika during five years 1999, 2004, 2009, 2014 and 2019 to compare the change in land use, crop sown structure, country production, unit area average yield and estimation of unit area pollution with major nutrients. The study showed an increased land used for the production of vegetables by (+ 37.84%) during the period from 2004 to 2014, high productivity per hectare for three crops from 2014 to 2019. Jordan had the highest tomato and paprika crop yields in 2014. The reason is due to the increase in the local and global demand for these crops along with other reasons, which have promoted the use of mass production agricultural techniques, the most important of which is chemical fertilization. Which caused the accumulation of phosphorus and potassium in soils.

    In the past few decades there has been an increasing pressure of population all over the world,
    especially in India, resulting in the utilization of every available patch of available land from
    woodlands to badlands. The study area represents a basin which is economically growing fast by
    converting the fallow lands, badlands and woodlands to agricultural land for the past few decades.
    IRS (Indian Remote sensing Satellites) 1 C – LISS III and IRS 1 C PAN and IRS P6 – LISS III and
    IRS 1 D PAN Images were merged to generate imageries with resolution matching to the landscape
    processes operating in the area. The images of the year 1997, 2000, 2004 and 2007 were analyzed to
    detect the changes in the landuse and landcover in the past ten years. The analysis reveals that there
    has been 20% increase in the agricultural area over the past ten years. Built up area also has increased
    from 1.35% to 6.36% of the area and dense vegetation also has marginally increased. The remarkable
    increase in the agricultural area occurs owing to the reclaim of the natural ravines and fallow lands.
    Presently the area looks promising, but it is necessary to understand the sedimentological and
    geomorphological characteristics of the area before massive invasion on any such landscapes because
    the benefit may be short lived.
