Abstrak.  Perencanaan dan penataan kembali penggunaan lahan diperlukan dengan pertumbuhan penduduk yang cepat. Penggunaan lahan yang bersifat dinamis serta pertumbuhan jumlah penduduk mendorong untuk dilakukannya perencanaan dan pemantauan pemanfaatan ruang di suatu lokasi daerah yang berdekatan dengan kota. Hal tersebut sangat mempengaruhi tingkat kepadatan penduduk dan perubahan penggunaan lahan yang terjadi. Adapun tujuan penelitian adalah untuk memetakan penggunaan lahan di Kota Lhokseumawe. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan teknik survey. Hasil kajian menunjukkan penggunaan lahan yang terbesar yaitu RTH (Ruang Terbuka Hijau) dengan luas 5.613,92 ha (38,64%) dan penggunaan lahan yang paling kecil yaitu PPI (Pangkalan Penampungan Ikan) dengan luas 3,23 ha (0,02%) dari luas keseluruhan wilayah.(Visual Classification on Screen Satellite Imagery for Land Use (Study Case: Lhokseumawe City)Abstract. Planning and realignment of land use is needed with rapid population growth, dynamic land use and population growth encourage planning and monitoring of spatial use in a location near the city. This greatly affects the level of population density and land use changes that occur. The research objective is to map the land use in Lhokseumawe City. The method used in this research is descriptive method with survey techniques. The results of the study show the largest land use namely green space with an area of 5,613.92 ha (38.64%) and the smallest land use namely fish shelter base with an area 3,23 ha (0,02%) of the total area.

This study evaluates the impacts of land use and climate changes on daily discharge in Ouémé river basin at Bétérou outlet. Observed rainfall and temperature over 2002–2008 and land use data of 2003 and 2007 were used. Corrected rainfall and temperature data, under RCP4.5 and RCP8.5 scenarios from regional climate model REMO were considered. Two land use scenarios from RIVERTWIN project were used. The first one, Land Use A (LUA), is characterized by stronger economic development, controlled urbanization, implementation of large-scale irrigation schemes, and 3.2% population growth per year. The other one, Land Use B (LUB), is characterized by a weak national economy, uncontrolled settlement, and farmland development as well as 3.5% population growth per year. Four climate and land use combined scenarios (LUA + RCP4.5, LUA + RCP8.5; LUB + RCP4.5, and LUB + RCP8.5) were used for forcing LISFLOOD hydrological model to estimate future discharges at 2050. As a result, during calibration and validation, the LISFLOOD model showed high ability to reproduce historical flows of Ouémé River at Bétérou outlet with Nash–Sutcliffe efficiencies greater than 90%. Future discharges simulations show general increase for all land use and climate combined scenarios for all time horizons until 2050. The increase is more exacerbated under the combined scenarios using LUB than the ones using LUA. Increase of river discharge varies between 7.1% and 52% compared to the mean of the reference period 2002–2004. These findings highlight growing challenges for water resources managers and planners. Moreover, they emphasize the need to address potential climate and land use changes’ impact on water resources. Then, developing water management plans, strategies to reduce flooding risks must be considered.

Context The processes regulating ungulate populations have been the focus of numerous studies. For the African buffalo (Syncerus caffer Sparrman) population inhabiting the Mara–Serengeti ecosystem, rinderpest was the primary regulatory factor up to the mid-1960s. Following reduction of rinderpest and buffalo population increase, interspecific competition for food, notably with cattle and wildebeest (Connochaetes taurinus Burchell), was thought to be the primary regulatory factor in the ecosystem. Aims We analysed buffalo population trends and the relationship between buffalo population growth and rainfall and density dependence in the Mara–Serengeti ecosystem and discuss the findings in the context of the key ecosystem processes governing buffalo population dynamics in African savannas, namely, food limitation, competition, predation, disease and land use changes. Methods We analysed buffalo population dynamics in the Mara–Serengeti ecosystem in relation to rainfall and density dependence feedback between 1984 and 2010. Key results Buffalo population growth was both significantly density-dependent and positively correlated with the dry season rainfall after, but not before, a severe drought in 1993. Buffalo numbers crashed by 48.6% in 1984–85 and by 76.1% in 1993–94 during severe droughts when food availability was lowest and competition with the more numerous cattle and wildebeest was highest. Conclusions Recovery of buffalo numbers to pre-drought levels took 8–9 years after the 1984–85 drought but was much slower, with buffaloes numbering merely 36% of their 1993 population (12 895 animals) 18 years after the 1993–94 drought despite intermittent periods of high rainfall, probably due to demographic and/or reproductive factors, heightened competition with livestock, land use changes in the adjoining pastoral ranches, lion predation and recurrent severe droughts. Implications Our findings demonstrate how food limitation caused by droughts associated with the hemispheric El Niño–Southern Oscillation can cause severe declines in and threaten the persistence of large ungulate populations. The findings also portray how density-dependent food limitation, competition, predation, land use changes and other factors can accentuate the effect of droughts and greatly prolong population recovery.

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.

The paper focuses on determining the degree of correlation between land-use changes and demographic development in Slovenia. The authors conclude that there is still insufficient evidence in the literature for a correlation between these two processes, because quantitative studies addressing these links are very rare and mostly cover small and specific areas. In the case of Slovenia, Spearman’s correlation coefficients are quite low, which confirms that land-use change processes are complex and not dependent solely on individual demographic and socioeconomic factors. Despite the low correlation coefficients, our findings indicate that changes in land use are significantly influenced by changes in age structure and population growth. In areas with population growth the share of arable land is shrinking, whereas in areas with depopulation and a rising aging index the share of partially overgrown land is growing. In the following analysis, the authors focus their analysis on a case study of the Mura and Central Slovenia statistical regions, which lie on opposite poles with regard to development, and thus show differing trends in land-use changes.

Abstract. Bantul Regency is a part of Yogyakarta Special Province Province which experienced land use changes. This research aims to assess the changes of shape and level of land use, to analyze the pattern of land use changes, and to find the appropriateness of RTRW land use in Bantul District in 2011-2015. Analytical methods are employed including Geoprocessing techniques and analysis of patterns of distribution of land use changes with Spatial Autocorrelation (Global Moran's I). The results of this study of land use in 2011, there are thirty one classifications, while in 2015 there are thirty four classifications. The pattern of distribution of land use change shows that land use change in 2011-2015 has a Complete Spatial Randomness pattern. Land use suitability with the direction of area function at RTRW is 24030,406 Ha (46,995406%) and incompatibility of 27103,115 Ha or equal to 53,004593% of the total area of Bantul Regency.Keywords: Geographical Information System, Land Use, Geoprocessing, Global Moran's I, Bantul Regency. Abstrak.
