| The over population is considered to be the most important problem facing Egypt in the current and next century which fizzle out every effects for future development. The urban encroachment on cultivated soils is a result of the over population which leads to increase the gap between production and demand of food. The government should think hardly to find out non-traditional solutions to prevent the urbanization on productive soils soon and keep it from deterioration. On the other hand, land reclamation programs in Egypt move with slowly steps due to their high cost and do not achieve the demanded results. Biba city, Beni Sweif governorate, in the north of Upper Egypt was selected to study the rate of loss in productive soils by urbanization impact during the period from 1947 to 2004. The urban areas were estimated in years 1947, 1985 and 2004 using detailed maps of scale 1:2500 established in 1947, aerial photographic maps of scale 1:2500 produced In 1985 and the maps extracted from landsat of scale 1:2500 covering the same area produced in 2004. The study revealed that the urban areas were 104.3, 135.7 and 158.85 feddan in the years 1947, 1985 and 2004 respectively, with an increasing rate of 1.22 feddan/year (1985 - 2004) and loss of cultivated soil with a rate of 0.83 feddan/year (1947 - 1985) and 1.22 fed./year (1985 - 2604). The study showed that, increasing population percent by 24.97% leads to increase the population density to 363 person/fed, compared with the national rate (150 person/feddan) in the period 1985-2004. The data elucidated also that the loss of the geographical area was 23.15 fed which equals 46.30 fed. of the cropped area; considering that the area is cultivated twice yearly. The estimation average of annual agricultural production return of such area ranged from 3247.82 LE. to 150362 L.E. yearly for the total lost area (1985-2004). | ||
