    Developing a suitability index for land uses and agricultural land covers
    (Springer, 2005) Kiliç, S; Evrendilek, F; Senol, S; Çelik, I
    This study was aimed at determining the land-use and land-cover (LULC) potentials of a southeastern Mediterranean area (Antakya, Turkey) of 36 816 ha for a total of 23 different LULC types: nine horticultural crops, nine field crops and five non-agricultural lands. Land evaluation was carried out by using a combination of SENOL Land Evaluation System and ILSEN computer program adapted to Turkey from FAO land evaluation principles. Our assessment resulted in the identification of nine physiographical units, 27 different soil series, and 110 land mapping units. Nearly 49% of the study area was determined as suitable for agricultural land cover types, and 35% for non-agricultural land use types. A map showing potential suitability of LULC was derived for the study area. The quantification of LULC suitability assists decision makers in ensuring that lands are used according to their capacities to satisfy human needs for present and future generations, thus sustaining ecological and economic productivity of natural resources.

    History of rainfed agriculture in Turkey
    (Soil Conservation & Watershed Management Research Center, 1997) Aydin, M; Kiliç, S
    Turkey, like most other Mediterranean countries, is an arid and semi-arid country. Turkey is also experiencing a population boom. This increase in population has led people to boost agricultural production by cultivating marginal land. In fact, until 1970, increases in food crop production were caused mostly by increases in the area of land that was cleared and cultivated. After 1970, with the help of more sophisticated techniques and more modern equipment, farmers aimed to conserve the moisture in the soil profile and produce greater yields by controlling the time of tilling, how many times a year soil was disturbed, and how deeply soil was cultivated. For a time; these new farming practices appeared to resolve Turkey's agricultural production problems. Between 1970 and 1990 while the area cultivated in wheat increased by only 9 % wheat production increased by 90 %. Nevertheless, Turkish farmers had much to learn about contending with periods of low rainfall, such as in 1989, when wheat production declined by 20 % from the year before. By the early 1990s, the increasing rate of production clearly showed that it was time to establish new guidelines for sustainable agriculture, particularly in the nation's dry regions. Indeed lack of rain during the growing season on the Central Plateau and other semiarid regions of Turkey poses the greatest challenge to the nation's agriculturalists. To address the pressing need for water the Turkish government launched the Southeastern Anatolian Development Project in 1987. The project covers an area of 74,000 km(2), roughly equal to one-tenth of Turkey's land surface. The project consists of 13 subprojects on the Euphrates and Tigris rivers.

    Seroepidemiology of leptospirosis, toxoplasmosis, and leishmaniosis among dogs in Ankara, Turkey
    (Elsevier Science Bv, 2005) Aslantas, O; Özdemir, V; Kiliç, S; Babür, C
    Seroprevalence of five different Leptospira interrogans serovars, Toxoplasma gondii and Leishmania infantum in stray dogs in Ankara was investigated. A total of 116 dog sera collected from apparently healthy stray dogs were tested for L interrogans serovars by microscopic agglutination test (MAT), for T gondii antibodies by Sabin-Feldman dye test (SFDT), and for L. infantum antibodies by indirect fluoresence antibody test (IFAT). Of the 116 dogs, 51 (43.96%) were seropositive for leptospirosis, 72 (62.06%) for T gondii and 3 (2.58%) for L. infantum. No statistically significant difference was observed between male and female dogs in the seroprevalences of toxoplasmosis and leptospirosis (P > 0.05), but statistically significant difference was observed among different age groups in the seroprevalences of toxoplasmosis and leptospirosis (P < 0.05). Although the seroprevalence of L. infantum was low, asymptomatic animals should be considered as a reservoir for the spread of the disease. (c) 2005 Elsevier B.V. All rights reserved.
