    Latin America and the Caribbean, Cuba

    El presente trabajo estudia las principales transformaciones introducidas en la economía cubana en el periodo de 1975 a 2013, con un énfasis particular en la Tercera Reforma Agraria puesta en vigor a partir de 1993, la cual significó el tránsito hacia un nuevo modelo agrario cuyo objetivo principal sería resolver el problema de la soberanía alimenticia. Con esta nueva reforma agraria se reconfigura una vez más la forma de tenencia de la tierra en Cuba, estando actual- mente el 54% (de las tierras) en manos del Estado y el 46% restante es propiedad no estatal.

    Latin America and the Caribbean, Cuba

    Entre 1959 y 2008, no se había contemplado en Cuba redistribuir tierras a gran escala a productores individuales. Desde 1990, varias políticas de redistribución del uso de la tierra se aplicaron con importantes impactos, pero las áreas involucradas no alcanzaron un tamaño significativo a nivel nacional. A partir de 2008,ocurre una innovación mayor en la política agraria, con la entrega de muchas tierras ociosas en usufructo a productores sin tierras o con poca tierra. Un cambio de esta naturaleza y magnitud amerita ser descrito y analizado.

    Cette étude, menée à l’est de la ville de Lomé (capitale et plus grande ville du Togo), met en évidence la dynamique spatiale des cultures maraîchères en réponse à la pression foncière. Des images satellitaires TerraMetrics des archives Google Earth des années 2002, 2008 et 2014 ont été retenues pour l’analyse de l’évolution des périmètres maraîchers. Une enquête de terrain fondée sur des questionnaires semi-structurés a été menée pour identifier les stratégies des maraîchers. Les coordonnées géographiques des points d’observation ont été relevées à l’aide d’un capteur GPS.

    Forests are under pressure from land use change due to anthropogenic activities. Land use change and harvest are the main disturbances of forest landscape changes. Few studies have focused on the relative contributions of different disturbances. In this study, we used the CA-Markov model, a land-use change model, coupled with a forest landscape model, LANDIS-II, to simulate dynamic change in Taihe County, China, from 2010 to 2050. Scenarios analysis was conducted to quantify the relative contributions of land use change and harvest.

    When developing land to meet various human needs, conducting assessments of different alternatives regarding their sustainability is critical. Among different alternatives of land-use, devoting land to bioenergy is relatively novel, in high demand, and important for addressing the energy crisis and mitigating carbon emissions. Furthermore, the competition and disputes among limited land-use for bioenergy and the combination of food production and housing are tense. Thus, which alternative of land-use is more sustainable is an important question, yet it is still under-investigated.

    In Hong Kong, reclamation is the main method for developing new land use areas as most country parks and mountains are protected under a land policy that emphasizes conservation for their high ecological value. Therefore, the land use for urbanized area in Hong Kong is limited, which has become an issue of concern. Hong Kong’s population is increasing; however, the amount of available land use is insufficient to meet the demand. Developing a high density of buildings is one of the critical strategies of Hong Kong’s government.

    While an increase in the size and number of conservation areas is expected as part of global environmental commitments, at the same time, Protected Area Downgrading, Downsizing, and Degazettement, or PADDD, is becoming more frequent worldwide. This paper analyzes the causal relationships between land claims and human settlements on the one hand and the downsizing process of a protective forest in southeastern Ecuador on the other.

    The lack of land ownership databases in developing countries has influenced inhabitants of these countries to occupy public lands. This situation has resulted in areas of informal housing, commerce, and agriculture, ultimately creating new informal settlements, which are becoming a serious problem in developing countries. These informal settlements contain inhabitants settled on public land without any infrastructure and against the landowner’s wishes.

    This article summarized the spatiotemporal pattern of land use/land cover (LU/LC) and urban heat island (UHI) dynamics in the Metropolitan city of Tehran between 1988 and 2018. The study showed dynamics of each LU/LC class and their role in influencing the UHI. The impervious surface area expanded by 286.04 (48.27% of total land) and vegetated land was depleted by 42.06 km2 (7.10% of total land) during the period of 1988–2018.
