This research summarizes land use and city expansion, as well as the dynamics of urbanization, over recent years in Ulaanbaatar city, Mongolia. The study applies fractal geometry to describe land uses in Ulaanbaatar city using a mathematical procedure and geographic information system (GIS) urban analysis, and measures urban sprawl using an index relation of area and perimeter. Land-use parcels’ shape, area perimeter relations, sprawl statement and geometry of city structure are considered. The research presents the growth of Ulaanbaatar city in two time series, 2000 and 2010.
Interactions between Food Security and Land Use in the Context of Global Change
Increases in human population and per-capita consumption are putting enormous pressure on land resources. About 38% of the Earth’s land area is being used in agricultural production [1], with about half (ca. 31%) of the remaining land being under forest cover [2] and the other half being less suitable for agricultural production due to edaphic, topographic and/or climatic factors. Despite the fact that over the last three decades the world food production has doubled [3], about 1 in 9 people in the world is still undernourished [4].
Making Sense of Past, Present and Future. Images of Modern and Past Pastoralism among Nyangatom Herders in South Omo, Ethiopia
This article asks how Nyangatom pastoralists currently make sense of the past, present and future of their pastoralist livelihood. Nyangatom pastoralists, like all agro-pastoralist groups in southern Ethiopia, are faced with enormous structural changes in their immediate surroundings, primarily due to large-scale industrial agriculture and a government policy encouraging them to be sedentary. While the impacts have been discussed elsewhere, thus far little focus has been placed on what images of the past, present and future these changes create among the Nyangatom.
Contribution of Traditional Farming to Ecosystem Services Provision: Case Studies from Slovakia
The main aim of this study is to assess the benefits provided by the ecosystems of traditional agricultural landscapes (TAL) and compare them to the outputs of large-scale agriculture. Assessment of ecosystem services (ES) was performed in four case-study areas situated in Slovakia, representing different types of TAL: Viticultural landscape, meadow–pasture landscape, and agricultural landscape with dispersed settlements and mosaics of orchards. The methodological approach was focused on assessment of all the principal types of ES—regulation and maintenance, provisioning, and cultural.
Approximating Forest Resource Dynamics in Peninsular Malaysia Using Parametric and Nonparametric Models, and Its Implications for Establishing Forest Reference (Emission) Levels under REDD+
Forest reference (emission) levels (FREL/FRLs) are baselines for REDD+, and 34 countries have submitted their FREL/FRLs to UNFCCC by January 2018. Most of them used simple historical average without considering the stages of forest transition. This research suggested that the period of calculating FREL/FRLs of simple historical average should be properly chosen if these countries are occupying multiple stages or sub-stages of forest transition.
