DETERMINATION OF THE POTENTIAL BIOGAS ENERGYPRODUCTION AMOUNTS AND AREAS IN THE TIGRISBASIN USING GIS

Abstract

The increasing world population renders the developed energy sources of the industry insufficient, and existing energy sources become expensive. It is anticipated that the energy deficit will further increase in the future. Scientists are in search of new energy sources in the face of this fact. It is considered that the cattle breeding potential of the Southeastern Anatolia Region may increase both as a result of state supports and fertile lands. Determining the potential biogas energy production areas of the Southeastern Anatolia Region in terms of cattle breeding is possible with the use of today’s knowledge and technology. With this study, it was aimed to determine the obtainable biogas energy fields and the current situation for the provinces in the Tigris Basin (Diyarbakır, Mardin, Siirt, Batman, Şırnak). The number of cattle in the basin for 2015 was benefited from in this framework. The boundaries of the research provinces were drawn using ARCMAP 10.0 software by making geographical corrections. In order for the inquiries of each province to be made independently from other provinces, all boundaries were divided on the basis of provinces, districts and villages as separate layers. These data constitute the main material of the study. The number of cattle was entered into the database of Geographical Information System (GIS), and the obtainable potential biogas energy production areas were determined considering the amount of waste that will be left in the environment by cattle. The finding that a total of 2809939 tons of annual wet manure can be obtained in the study area was obtained. It was determined that a total of 1175912278 MJ biogas energy amount can be obtained per year from this wet manure. Furthermore, the project created with a cartographic base, the geographical correction of which was made, was assessed in accordance with the purpose of this study in the database, and the areas that are suitable, non-suitable or partially suitable for biogas energy production areas were determined.
