Ambarawa District has allegedly experienced many changes in land use. Changes in land use in Ambarawa District are dominated by changes in agricultural land to non-agricultural land. This is because the land in Ambarawa District is influenced by the role of its inhabitatns in utilizing the land so that it has an impact on land use change. This study aims to determine changes in land use, the factors that influence land use changes, the direction of development and what types of use changes are most dominant in Ambarawa District, Pringsewu Regency. The method used in this research is survei and image interpretation by looking at changes in land use in each area. The population used in this study were all villages in Ambarawa District, totaling 8 villages which were suspected of experiencing changes in land use. Collecting data in this study is a descriptive geospatial approach through the overlay technique of land use spatial data. The results showed that there was a change in land use in Ambarawa District year 2014-2019 covering an area of 2.195,8 ha (70,83%), which was caused by social and economic factors, namely the increase in population and workers and the direction of land use changes to the west and east.

<p>Bali is the most popular tourist destination with Ubud one of the tourist destinations with its beautiful landscapes and rice fields. Mas Village, Ubud is one of the tourist villages that has been inaugurated by the Gianyar Regency Government based on the Decree of the Gianyar Regent Number 429/E-02/HK/2017 regarding the establishment of a Tourism Village. Jalan Rapuan which is located in Tarukan Tourism Village, Mas is one of the strategic corridors in Mas Tourism Village because it is a stretch of rice fields that has a high tourism selling value. The purpose of this study is to identify changes in land use in 2013-2021 due to tourism activities seen from the aspects that have a dominant influence on land use changes. Quantitative method is the method used with primary and secondary data collection methods and stages of analysis in the form of descriptive analysis of tourism activities in Mas Village, statistical-descriptive analysis of land use change with overlay analysis on the Jalan Rapuan corridor. The results showed that there was a change in land use along the Rapuan corridor in 2013-2021 by 14% of the non-built land to be built in the form of tourist accommodation and housing. The indicators analyzed by factor analysis were able to explain important factors, namely external factors of 31.69%, internal factors of 23.821% and regulatory factors of 17.218% with a total of factors able to explain land use change of 72.73%.</p>

Land-use changes or land conversion issues not only poses a threat of ecological or environmental, but also trigger a variety of dynamics and complexity of social relations in it. West Cilebut Villages has been the target of investors and developers of housing since the 1990s, and now the West Cilebut Villages has changed from an area full of green “romantic” village, into the region filled with concrete. Therefore, this study was conducted to answer fundamental issues related to the issue of land conversion in the West Cilebut Village, first is to see the map and interests between actors in relation to land conversion in the West Cilebut Village, and second to know the social interactions dynamics that occur in West Cilebut community, following the land conversion from the farm into housing estates. The results showed that there are three main actors in relation to issues of land use change in West Cilebut Village: (1) The Housing Developer; (2) Village Apparatus / Government; (3) Society; where the three actors have a role and importance of different orientations. Meanwhile, social interaction between housing and rural communities basically shows a relationship of mutual need. Construction of housing community that luxurious and exclusive slowly turns into inclusive and reflect a resiprocity of the two communities.

The Kitulo Plateau of southern Tanzania is a lava plateau covering 273 sq km at an altitude of over 2500 m. The vegetation is predominately grassland with more than 350 taxa of vascular plants, of which nearly 5 per cent are of restricted distribution. Although the plateau is extensive, much of it is now cultivated. Digital analysis of satellite images showed that at least 24 per cent of the plateau was bare soil, modified grassland or cultivation between 1973 and 1989. The botanical importance of the plateau and increase in cultivation make a strong case for the establishment of a nature reserve to protect its rare and threatened plants.

Ba river is the biggest river system in the South-Central Coast of Vietnam and plays a significant role in the socio-economic development of the region. Recently, land-use changes in Gia Lai province have been significantly transformed. Hence, to provide the information for land-use planning, there is an urgent need for land-use change assessment in the upstream Ba river basin. This study employed the Markov chain coupled with GIS to assess land-use changes between 2010 - 2015 and 2015 - 2020 periods. The results showed that during the period 2010 - 2015, there was no significant conversion of agricultural and reserve forest land. Meanwhile, a large proportion of unused (86%) and water and aquacultural land (57.5%) was converted into the other land-use types. Between 2020 and 2015, unused land decreased while the surface water and aquacultural land increased. The forest land accounted for a significant area (51.16%) during the 2015 - 2020 period. In addition, the driving forces leading to these changes were also analyzed, providing a more comprehensive of land-use change in the study area. In general, GIS and Markov were suitable for assessing land-use change. This study outcomes provide a general framework for land-use planning in Gia Lai province.
