Land use in South Lampung Regency continues to experience development, which is influenced by rapid population growth within five years after the planning year began in 2010. Various types of land-use changes that have occurred in South Lampung Regency indicate in the spatial changes of South Lampung Regency, which has been planned especially in the Regional Spatial Plan (RTRW) of South Lampung Regency for 2011-2031, one of which is the plantation area (belonging to PTPN VII) to become land for ITERA. There are preventive measures that can be made so that the spatial plan can still be following its development objectives. It is necessary to research by evaluating South Lampung Regency's spatial use based on its spatial plan, especially by RTRW. Based on the analysis, there is a deviation of land use in South Lampung Regency with 48.46%, which is divided into spatial structure plans and spatial pattern plans.

Over Time

The Mexican Caribbean and its main cities have the highest population growth rate in Mexico. This work goal was to analyze the growth of the city of Chetumal and the geopedological characteristics in which it has been developed, to identify potential hazards and thereby improve development programs. The methodology consisted in the study of geopedological characteristics and the analysis of land use changes in the city over time. The main problems of Chetumal are floods and subsidence. Floods are more common in areas where Gleysols soils are found in low-lying areas. The subsidence is associated to Leptosols with a phreatic mantle at a shallow depth where the precipitations favors dissolution of rock. The extrapolation of the relationships between geopedological conditions and the area occupied by the city, allows us to suppose that areas which the current Urban Development Program proposes for future city expansion will develop the same problems of subsidence and flooding as the areas already built in sites with similar conditions.

Kabupaten Sleman memiliki banyak daya tarik yang memicu terjadinya urbanisasi yang dapat terlihat dari fenomeno perubahan penggunaan lahan . Perubahan penggunaan lahan di Kabupaten Sleman terjadi pada kawasan keamanan dan ketahanan pangan yang terdiri dari Kecamatan Moyudan, Minggir, Sayegan, Godean, Mlati, dan Tempel.  Fenomena perubahan penggunaan lahan penting untuk dikontrol dan dikendalikan karena kawasan tersebut memiliki peran penting bagi ketahanan pangan di Kabupaten Sleman. Metode penelitian yang digunakan adalah metode deskriptif. Di dalam metode deskriptif terdapat metode survey yang digunakaan untuk mengetahui kondisi eksisting penggunaan lahan di daerah penelitian. Sedangkan untuk perubahan penggunaan lahan pada kawasan keamanan dan ketahanan pangan di Kabupaten Sleman dari Tahun 2012 sampai Tahun 2018 diperoleh dengan metode overlay peta penggunaan lahan yang diperoleh dari Citra Quickbird pada tahun tersebut. Perubahan penggunaan lahan pada kawasan keamanan dan ketahanan pangan Kabupaten Sleman mencapai 57,33 km2 atau 33,93% dari luas total daerah penelitian. Perubahan penggunaan lahan didominasi oleh perubahan lahan sawah menjadi hutan produksi seluas 15,05 km2. Faktor pendorong adanya perubahan penggunaan lahan tersebut adalah produktivitas pertanian sawah yang semakin menurun tiap tahunnya.Sleman Regency has many attractions that trigger urbanization which can be seen from the phenomenon of land-use change. This phenomenon occurs in Sleman Regency particularly in the area of food security and sustainability which is spreading in various districts such as Moyudan, Minggir, Sayegan, Godean, Mlati, and Tempel. The phenomenon of land change must be managed and controlled because the areas have an important role for food security in Sleman Regency. The method used for the research is descriptive method. Survey is a part of descriptive method which used to determine the existing conditions of land use in the research object areas. Whereas for land-use changes in the area of food security and sustainability in Sleman Regency from 2012 to 2018 was obtained with the method of land-use map overlay obtained from Quickbird imagery in those years.Land-use change in the area of food security and sustainability of  Sleman Regency reaches 57.33 km2 or 33.93% from the total of research study area. Land-use change is dominated by the diversions of rice fields to forests that reach 15.05 km2. The driving factor for this phenomenon is the decreasing annual productivity of rice field.

<p class="Abstract"><em>Gijón, also known as Xixón, is an important city that rivals Oviedo, the historical capital of the Autonomous Region and Principality of Asturias (Spain), in historical demographic and economic terms. It has traditionally been a port and, more recently, an industrial city, which experienced very rapid population growth and with little planning. After the industrial crisis of the 80s, the city wanted to become a tourist location more than an industrial harbor. Both its privileged location and the historical urban heritage that still remain are corner stones to make this change possible. However, the late and strict legislation (improvised to protect the last remains of a previously uncontrolled development) impeded a necessary urban re-design in order to shelter the new touristic supplies. This paper proposes some urban solutions to selectively modify the catalogue according with the cultural and touristic potentials of the city. These solutions were agreed by the working group set up by Gijón City Council and ERDU (Estudio de Renovación y Desarrollos Urbanos -Urban Renovation and Development Studio).</em></p><em><em><br /></em></em>

The expansion of urban areas and the increase in the number of buildings and urbanization characteristics, such as roads, affect the meteorological environment in urban areas, resulting in weakened pollutant dispersion. First, this paper uses GIS (geographic information system) spatial analysis technology and landscape ecology analysis methods to analyze the dynamic changes in land cover and landscape patterns in Chengdu as a result of urban development. Second, the most appropriate WRF (Weather Research and Forecasting) model parameterization scheme is selected and screened. Land-use data from different development stages in the city are included in the model, and the wind speed and temperature results simulated using new and old land-use data (1980 and 2015) are evaluated and compared. Finally, the results of the numerical simulations by the WRF-Chem air quality model using new and old land-use data are coupled with 0.25° × 0.25°-resolution MEIC (Multi-resolution Emission Inventory for China) emission source data from Tsinghua University. The results of the sensitivity experiments using the WRF-Chem model for the city under different development conditions and during different periods are discussed. The meteorological conditions and pollution sources remained unchanged as the land-use data changed, which revealed the impact of urban land-use changes on the simulation results of PM2.5 atmospheric pollutants. The results show the following. (1) From 1980 to 2015, the land-use changes in Chengdu were obvious, and cultivated land exhibited the greatest changes, followed by forestland. Under the influence of urban land-use dynamics and human activities, both the richness and evenness of the landscape in Chengdu increased. (2) The microphysical scheme WSM3 (WRF Single–Moment 3 class) and land-surface scheme SLAB (5-layer diffusion scheme) were the most suitable for simulating temperatures and wind speeds in the WRF model. The wind speed and temperature simulation results using the 2015 land-use data were better than those using the 1980 land-use data when assessed according to the coincidence index and correlation coefficient. (3) The WRF-Chem simulation results obtained for PM2.5 using the 2015 land-use data were better than those obtained using the 1980 land-use data in terms of the correlation coefficient and standard deviation. The concentration of PM2.5 in urban areas was higher than that in the suburbs, and the concentration of PM2.5 was lower on Longquan Mountain in Chengdu than in the surrounding areas.

Abstract. The factors that contribute to land use change in the municipality of Gaúcha do Norte - MT, are entirely linked to the economic process and agricultural production. This process has left Brazil in a state of alert due to the process of deforestation and loss of tropical forests. From 2000 to 2010, the forest areas converted into agriculture accounted for 13.3%, the main factor that directly potentiated with deforestation was the cultivation of soybeans, which in turn was occupying places previously occupied by livestock and pushing the livestock forest inside. The phenomena of land use change and land cover start from multidimensional issues in the environmental and economic context. The use of environmental modeling through cellular automata to analyze land use change phenomena and reproduce the trajectory through future land use simulations and evolution establishes an integration associated by mathematical models and flow integration systems. That predict the trajectory of land use change, thus generating a dynamic model capable of predicting future land use changes by replicating possible patterns of landscape evolution and enabling assessments of future ecological implications for the environment.

Temporal changes of sediment dynamics within the Nairobi River sub-basins between 1998-2006 time scale, Kenya The city of Nairobi is the heart of both industrial production and the economic hub in Kenya and the Eastern Africa region. The city of Nairobi and its environs are drained by three streams, namely: Nairobi, Mathare and Ngong rivers. These streams drain areas of diverse land use activities. The land use changes in a spatial manner from the rich agricultural system through residential cum urban to industrial. The significance of these various land use systems to pollutants generation, pollution, sediment generation and hence water pollution and quality degradation is quite enormous and worth investigation. The land use changes in a spatial manner making the basin ideal for a temporal variation of sediments yields along the river profile and their impacts on the water quality status. This paper examines the results of study carried out within the basins in the years 1998-2006. The method of study involved water sampling and laboratory analysis to reveal the trends in sediment load increases downstream the investigated streams. Soil samples were also investigated to determine their relationship to soil erosion rates and sediment fluxes. The study attempts further to find the best sediment management strategies in reversing their increasing trends and restoring water quality within the basin.
