Demak is known as the second largest region suffering land use change in Java’s North Coast. The topographic condition in downstream affects this area becomes susceptible with flood hazard. This research aims to assess the interactions between flooding, land use change and encroachment activities in Mijen and Wedung sub districts, Demak region, Central Java, Indonesia. This research combines the Driving Force, Pressure, State, Impact and Response (DPSIR) analysis. The supervised classification by Maximum Likelihood of time series Landsat images (2000, 2009 and 2014) was chosen for land cover analysis. The land use change shows that paddy field area descended almost 6%, mangrove forest fall 79% meanwhile settlement grown up almost double in 2000-2014. The result of overall accuracy assessment is 78.23%. The DPSIR result shows that land use change not too affect the flood events but floods influence land use pattern in north and south area of Mijen and Wedung.  AbstrakDemak merupakan daerah tertinggi kedua yang mengalami perubahan penggunaan lahan di wilayah Pantai Utara Jawa (PANTURA). Kondisi topografinya yang berada di daerah hilir mengakibatkan daerah ini rawan bencana banjir. Penelitian ini bertujuan untuk menganalisa interaksi antara banjir, perubahan penggunaan lahan dan aktivitas yang mengakibatkan perubahan lahan di kecamatan Mijen dan Wedung, Kabupaten Demak, Jawa Tengah-Indonesia. Penelitian ini menerapkan analisis DPSIR (Penyebab Utama, Tekanan, Keadaan, Akibat dan Respon) guna memahami akar permasalahan dan efek berantai dari hubungan tersebut. Klasifikasi terbimbing dengan Maximum Likelihood dari Citra Landsat (2000, 2009 dan 2014) dipilih untuk pemetaan dan analisis tutupan lahan. Hasil perubahan penggunaan lahan menunjukkan bahwa sawah berkurang 6%, hutan mangrove terdegradasi sebanyak 79% sedangkan pemukiman berkembang dua kali lipat selama periode 2000-2014. Hasil analisis akurasi menunjukkan nilai sebesar 78.23 %. Hasil analisis DPSIR menunjukkan bahwa perubahan penggunaan lahan tidak terlalu mempengaruhi kejadian banjir tetapi banjir mempengaruhi pola penggunaan lahan di bagian utara dan selatan wilayah Demak.

Objective: This article describes and analyzes the main concepts of coastal ecosystems, these as a result of research concerning land-use change assessments in coastal areas. Design/Methodology/Approach: Scientific articles were searched using keywords in English and Spanish. Articles regarding land-use change assessment in coastal areas were selected, discarding those that although being on coastal zones and geographic and soil identification did not use Geographic Information System (GIS). Results: A GIS is a computer-based tool for evaluating the land-use change in coastal areas by quantifying variations. It is analyzed through GIS and its contributions; highlighting its importance and constant monitoring. Limitations of the study/Implications: This research analyzes national and international scientific information, published from 2007 to 2019, regarding the land-use change in coastal areas quantified with the digital GIS tool. Findings/Conclusions: GIS are useful tools in the identification and quantitative evaluation of changes in land-use in coastal ecosystems; which require constant evaluation due to their high dynamism.

Conversion of native vegetation into farmed grassland in the Lake Taupo catchment commenced in the late 1950s. The lake's iconic value is being threatened by the slow decline in lake water quality that has become apparent since the 1970s. Keywords: satellite remote sensing, nitrate leaching, land use change, livestock farming, land management
