Alih fungsi lahan pertanian ke non pertanian menjadi permasalahan di kawasan pinggiran perkotaan. Alih fungsi lahan ini disebabkan land rent lahan pertanian tidak menguntungkan dibandingkan jika dibandingkan dengan lahan komersil. Jika kondisi ini terus berlanjut maka akan mengancam ketahanan pangan suatu wilayah. Penelitian ini bertujuan untuk memodelkan penentuan lahan sawah berkelanjutan berdasarkan analisis spasial dan teknik penginderaan jauh. Analisis yang digunakan meliputi analisis interpretasi citra, Geography Information System (GIS), analisis statistik, dan analisis prediksi ketersediaan lahan sawah. Penelitian ini dilakukan di Kabupaten Semarang dengan perkembangan perkotaan yang cepat. Variabel dalam menyusun model lahan sawah berkelanjutan ini terdiri dari variabel produktivitas tanaman, kepadatan dan jangkauan jaringan jalan dan sungai, kawasan lindung, serta proyeksi arah perkembangan perkotaan. Hasil analisis produktivitas tanaman menghasilkan persamaan statistik produktivitas (ton/ha) = 3,795 (NDVI) + 3,774 dan nilai r² sebesar 0,854. Terdapat selisih antara data dinas dengan data peneliti sebesar 2,8% dari luas lahan pertanian eksisiting. Selisish luas ini dikarenakan perbedaan skala peta, proses analisis, dan metode yang digunakan. Berdasarkan hasil analisis dan pembahasan maka dapat disimpulkan bahwa lahan sawah berkelanjutan ketersediannya mulai berkurang, sehingga perlu adanya ketegasan pemerintah daerah dalam menjaga ketersedian lahan sawah.

<p class="04CorpodoTexto">Este artigo tem por objetivo aplicar geotecnologias para obtenção de informações planialtimétricas a fim de avaliar a viabilidade de implantação do campus Centro Histórico/Itaqui-Bacanga do IFMA. Considerando que para realização de levantamento por métodos tradicionais é recomendado que seja realizado o destocamento e a limpeza do terreno previamente, avaliou-se a realização do levantamento planialtimétrico a partir de um par de receptores <em>Global Navigation Satellite System</em> (GNSS) pelo método <em>Real Time Kinematic</em> (RTK) pós processado e também a partir da realização de levantamento fotogramétrico, utilizando aeronave remotamente pilotada (ARP), popularmente conhecida como drone. Esta análise permitiu demonstrar que o aerolevantamento com a ARP pode ser aplicado na concepção inicial de um projeto de engenharia, conforme classificação do Tribunal de Contas da União (TCU) para níveis de precisão, pois obteve-se uma diferença orçamentária de 19% entre os projetos elaborados a partir das duas geotecnologias.</p><div> </div>

Enthusiasm for accuracy farming practices and advances is becoming quickly all through the agrarian world. The accuracy farming can make utilization of the current methods, for example, GPS (Global Positioning System) innovation, GIS (Geographical Information System) innovation, RS (Remote Sensing) innovation and ES (Expert System) innovation et cetera, with a specific end goal to separate the agribusiness specialized measures among plots to acquire the better peripheral advantage of economy and environment. The study demonstrates to those generally accepted methods to utilize GIS (Geography Information System), Data mining and Web innovations in the rural master choice framework. This security with mass storage is satisfied by using GIS cloud server. This chapter discuss with an Integrated Geographic Information System with ES using Cloud Computing.

Climate change challenges mountain communities to prepare themselves via Community-Based Adaptation (CBA) plans that reduce vulnerability. This paper outlines the evaluation of a developed web-based information system to support CBA, referred to as a Mountain Community Adaptive System (MCAS). The web-based user interface visualizes collated data from data providers, integrating it with near real-time climate and weather datasets. The interface provides more up-to-date information than was previously available on the environment, particularly on land and climate. MCAS, a cloud-based Land Information System (LIS), was developed using an Agile-inspired approach offering system creation based on bare minimum system requirements and iterative development. The system was tested against Fit-For-Purpose Land Administration (FFP LA) criteria to assess the effectiveness in a case from Nepal. The results illustrate that an MCAS-style system can provide useful information such as land use status, adaptation options, near real-time rainfall and temperature details, amongst others, to enable services that can enhance CBA activities. The information can facilitate improved CBA planning and implementation at the mountain community level. Despite the mentioned benefits of MCAS, ensuring system access was identified as a key limitation: smartphones and mobile technologies still remain prohibitively expensive for members of mountain communities, and underlying information communication technology (ICT) infrastructures remain under-developed in the assessed mountain communities. The results of the evaluation further suggest that the land-related aspects of climate change should be added to CBA initiatives. Similarly, existing LIS could have functionalities extended to include climate-related variables that impact on land use, tenure, and development.

With the rapid development of social and economy, land use/cover change (LUCC) has been regard as a critical effect of global environment change. Researches on LUCC convert from single factor influence to overall research on the effects of regional ecological environment. Research Scope of study area gradually changes from the ecological fragile areas in the western to developed areas. This paper summarized the main methods of effect of land use change on the evaluate of eco-environment research. The results show that: environmental effects of land use/cover change improved in the long term; the rapid progress of remote sensing technology and geographic information system make environmental effects of land use/cover change more convenient.
