Abstract
The effect of human intervention on the agricultural system has shown food insecurity with an increase in the cost of crop production in the local market due to the expansion of urbanization in the study area with 2.66% in 9 years for the demand of residential land. and also beyond this simulation result, the impact of deforestation on urban Agricultural and livelihoods was not scientifically studied in most of the southern Ethiopia high lands and their surrounding in particularly for Wolayta zone sodo zuria woreda has shown 0.295 % per year of forestland declined by 0.09 % for residential land and it has used for public service during the selected study period. This study has focused on the impact of urbanization rate and land use land cover change detection analysis using Primate and secondary data source with integration (GIS) Geographic Information System and Remote sensing Method for managing the negative impact on the geospatial environment in the context of Ethiopian Agricultural Transformation (ATP) goal of sustainable development. And evaluation of image classification accuracy can be defined as the process of comparing the classified image with geographic data considered to be accurate and referential typically, the data which is classified image is compared to are ground-truth based on supervised classification with (CR) Consistency Ratio 0.016 % of the pixel has resulted for accuracy assessment of 30m Land Sat 7 satellite image. In general, a set of reference shapefile has been overlaid as 7 major landuse class which are generated over the classified image by the AHP method of Computing Eigenvector Matrixes, which is an output of the pairwise comparison matrix to produce the best fit set based on the pixel value landuse area listed Keywords: Analytic Hierarchical Process (AHP), Geographic Information System (GIS), Land sat 7 (ETM+) and Eigenvector Matrixes DOI: 10.7176/CER/13-3-03 Publication date: May 31 st 2021

Urbanisation is growing due to population growth and rural-urban migration is one of the main reason and expansion of urbanization, it was a man-made phenomenon with inbuilt activity on the environment and natural resource, in addition, the intervention of humans in the natural environment influences the nature of ecosystem processes by the rate at which they operate on the environment especially farmland around the urban area (Angel et al, 2011; Jiang, 2015). one of its main factor which is deforestation, the removal of land cover vegetation into the extent that human need to have residence
According to United Nations Human Settlements Programme, 54.5 per cent of the world’s population resided in urban settings in 2016 based on this report by 2030, urban areas are projected to accommodate 60 per cent of the world population, and the urban population of developing countries will in increase with frequency of 2 per cent (UN, 2016) In other words, urbanisation can be defined as the transformation of forest and urban farmland to residential area and shifting cultivation area to urbanisation (FAO/UNEP, 1982)
3.1 Materials Data for this study were collected from the local government Authority one of the offices was Ethiopian Mapping Authority (EMA) for coordinate transformation, Wolayta Sodo municipality for land use shapefile of 2010 and 2019 Land sat 7 (ETM+) satellite image of an average spatial resolution taken on 09/ July 2019, from path/row 169/55 from USGS as user Registry of Bereket for cross-checking information
Summary
Urbanisation is growing due to population growth and rural-urban migration is one of the main reason and expansion of urbanization, it was a man-made phenomenon with inbuilt activity on the environment and natural resource, in addition, the intervention of humans in the natural environment influences the nature of ecosystem processes by the rate at which they operate on the environment especially farmland around the urban area (Angel et al, 2011; Jiang, 2015). one of its main factor which is deforestation, the removal of land cover vegetation into the extent that human need to have residence. More inclusive was Myers’s 1980 definition, where deforestation refers, “generally to the destruction of forest cover through clearing for agriculture land so that not a tree remains, and the land is given over to non-forest purposes and was] very heavy and unduly negligent logging results in a decline of biomass and depletion of ecosystem services So severe that the residual forest can no longer qualify as forest in any practical sense of the environment.” Based on this idea this study was focus on the impact of human operation through expanding urban residential area on urban farmland a case Wolayta sodo city south Ethiopia. One of the major challenges in the study area is environmental degradation coming from population pressure, land use urban residential expansion in addition weak urban agricultural domestic crop production, a lack of market value chain www.iiste.org with the low rank of integrated urban Agricultural technology transfer and inadequate input supply and marketing systems (Shiferaw & Singh, 2010)
