Description:	Tesis ini memberi tumpuan kepada kemerosotan alam sekitar yang disebabkan oleh amalan komuniti luar bandar di kawasan Ghebeish. Objektif kajian ini adalah untuk menyelidik kemerosotan alam sekitar terutamanya mengkaji perubahan yang berlaku pada litupan tumbuh-tumbuhan, amalan komuniti luar bandar dalam sistem pengeluaran tradisional, dan bagaimana penduduk di kawasan kajian melihat kemerosotan alam sekitar. Bagi mencapai objektif ini, soalselidik-temu bual telah dijalankan. Sejumlah 420 responden yang dipilih secara rawak telah diminta memberikan persepsi mereka terhadap kemerosotan alam sekitar semasa. Data curahan hujan untuk tempoh empat dekad yang lalu dan imej penderiaan jauh digunakan bagi pengumpulan data. Ujian khi-kuasa dua (chi square test), model regresi, pekali variasi, pekali korelasi, Eardas Imagine, dan ArcGIS telah digunakan dalam analisis data. Kajian ini menunjukkan bahawa sebahagian besar (91.6%) daripada responden sedar tentang kemerosotan alam sekitar. Mereka menganggap (65.7%) variasi dalam set data yang memaklumkan kehilangan beberapa spesies tumbuh-tumbuhan dan kemunculan spesies baru secara negatif. Selain daripada variasi dan turun naik curahan hujan (C.V = 0.33), kajian ini turut mendedahkan sistem pengeluaran pertanian tradisional, bahan binaan tempatan, pembuatan arang dan peningkatan dalam populasi manusia dan haiwan merupakan punca utama degradasi atau kemerosotan alam sekitar. Dapatan ini menunjukkan 85% daripada variasi dalam set data pada  = 0.01. Satu korelasi negatif di antara pembersihan awal tanah dan pengeluaran pertanian telah diperolehi (r = -0.42 pada  = 0.01). Kajian ini juga mendapati bahawa pokok renek dan kawasan penanaman masing-masing bertambah sebanyak 18.2% dan 31.8% sehingga menjejaskan kawasan yang dilitupi oleh rumput. Wadi dan hutan berkurangan pada kadar -1.47%, -0.081% dan -0.037% setiap tahun sejak dua puluh tujuh tahun yang lepas. Bagi mengurangkan kemerosotan alam sekitar, kajian ini mencadangkan penggunaan amalan penanaman moden bagi menggantikan amalan tradisional, peruntukan batu serta bata merah atau bata lumpur bagi menggantikan bahan binaan tempatan, dan juga penggunaan gas asli bagi menggantikan arang. Pemantauan berterusan terhadap penggunaan tanah melalui penderiaan jauh dan GIS dilihat sebagai kaedah yang amat diperlukan untuk menggambarkan kemerosotan alam sekitar.,This thesis focuses on environmental degradation caused by rural community practices in Ghebeish area. The objectives of the study are to investigate the environmental degradation specially tracing the changes in vegetation cover, the rural community practices in traditional production sector, and how humans in the study area perceive the environmental degradation. To achieve these objectives, questionnaire-interviews were conducted. A total number of (420) respondents randomly selected were asked for their perception on current environmental degradation. Rainfall data for the last four decades and remote sensing image is used for data collection. Chi-square test, regression model, coefficient of variation, correlation coefficient, Eardas Imagine and ArcGIS were used in the data analysis. The study pointed out that most (91.6%) of the respondents were aware of the environmental degradation. They perceived (65.7% the variation in the data set informing of disappearance of some vegetation species and appearance of new ones negatively. In addition to variation and fluctuation of rainfall, (C.V= 0.33) the study also revealed that traditional agricultural production system, local building materials, charcoal making and increase in human and animals' population have been the main causes of environmental degradation These show 85% of the variation in the data set at the r = 0.01. A negative correlation between early land clearing and agricultural production was established (r = -0.42 at the r = 0.01). The study also found that shrubs and cultivated areas increased by 18.2% and 31.8% respectively at the expense of areas covered by grass, Wadis and forests decreased by the rate of -1.47%, -0.081% and-0.037% per year in the last twenty seven years. To mitigate the environmental degradation, the researcher suggests the following: the adoption of the modern cultivation practices instead of the traditional ones, provision of stone, red or mud bricks instead of local building materials as well as using natural gas instead of charcoal. Continuous monitoring of land use through remote sensing and GIS is seen as indispensable methods in visualizing the environmental degradation.,PhD
