Satellite imagery acquired by IKONOS imaging system in 2003 and the analog map of the study area at scale 1:25000 (1984) have been used to estimate the population growth taken place in Halfaya Town. Remote sensing, digital image processing and GIS techniques were used to achieve the objectives of this study. Different procedures such as, image restoration, image enhancement, topology, spatial analysis and overlay have been applied to model the urban growth in the study area between the year 1984 and the year 2003 .Based on the developed GIS model of the study area the estimated population growth rate was found to be 233%. The study proved that integrated remote sensing and GIS techniques have great impact on detecting environmental changes and man-made features variations through time.

AbstractFrom strawberry-picking robots to satellite remote sensing and GIS techniques that forecast crop yields, the integration of robotics and AI in agriculture will play a key role in sustainably meeting the growing food demand of the future. But it also carries the risk of alienating a certain population, such as smallholder farmers and rural households, as digital technologies tend to be biased toward those with higher-level skills. To ensure that digital technologies are inclusive and become a driver for development, countries should make technology affordable and invest in institutions and human capital, so that everyone can participate in the new digital economy. Digital agriculture also represents an opportunity for young people as agriculture value chains can be developed to create new service jobs in rural areas, making agriculture an attractive sector for youth.
