    Four Decades of Forest Persistence, Clearance and Logging on Borneo
    Peer-reviewed publication
    July, 2014
    Brunei Darussalam, Malaysia

    The native forests of Borneo have been impacted by selective logging, fire, and conversion to plantations at unprecedented scales since industrial-scale extractive industries began in the early 1970s. There is no island-wide documentation of forest clearance or logging since the 1970s. This creates an information gap for conservation planning, especially with regard to selectively logged forests that maintain high conservation potential. Analysing LANDSAT images, we estimate that 75.7% (558,060 km2) of Borneo’s area (737,188 km2) was forested around 1973.

    Italy

    Over the past centuries, land systems in Italy experienced fundamental shifts, owing to the availability of new energy forms, population surges, and technological progress. The 20th century was characterized by massive productivity increases, accompanied by gradual land abandonment and the return of forest land. We here analyze 120 years of land system change in Italy, applying the human appropriation of net primary production (HANPP) framework, a metric for socio-economic pressures on terrestrial ecosystems.

    New Zealand

    Sustainable land management is essential to meeting the global challenge of securing soil and water resources that can support an ever increasing population. In Auckland, New Zealand's largest city, population growth is forecast to increase from 1.5 to 2.5 million by 2040 which will put immense pressure on the region's soil resources.

    When assessing soil organic carbon (SOC) sequestration and its climate change (CC) mitigation potential at global scale, the dynamic nature of soil carbon storage and interventions to foster it should be taken into account. Firstly, adoption of SOC-sequestration measures will take time, and reasonably such schemes could only be implemented gradually at large-scale. Secondly, if soils are managed as carbon sinks, then SOC will increase only over a limited time, up to the point when a new SOC equilibrium is reached.

    Rice terraces are paddy fields made on sloping land that follow the natural contour lines, suited to the Japanese landscape. The terraces blend in with the natural scenery and give viewers a great sense of peace and comfort. Rice terraces are also growing into a focus of agro tourism. However, farming on these rice terraces has low labor productivity, and with the advancing age of the farmers in the mountainous areas, it has become difficult for them to continue farming on the rice terraces. Their abandonment is now noticeable. For this research, one city sustaining the rice terraces viz.

    The effects of the surrounding stand type and forest site productivity on the composition and size of understory trees were examined in middle-aged Cryptomeria japonica plantations. A negative correlation was found between the stem density of hardwood colonized and the site index as an indicator of forest site productivity. The effect of the site index on the colonization of hardwood is greater than that of the measures of current light intensity.

    Chile

    Este texto analiza la modalidad de interrelation hispano/chilena-mapuche/huilliche en territorio valdiviano durante la colonia tardía y propone el concepto de "colonización fronteriza", a través del cual se busca diferenciar dicha región de otros procesos de interrelation hispano-indígena en Chile. En vista de este objetivo, el estudio se centra en el proceso de conformación de propiedad privada de la tierra, identificando algunas de las transformaciones que esto produce en la región valdiviana hacia fines del siglo XVIII.

    El objetivo de este trabajo es analizar la circulación de saberes agrícolas en el sureste productivo del Territorio Nacional de la Pampa durante la década del veinte, haciendo hincapié en el rol de las publicaciones especializadas, ya sea que pertenecieran a la esfera estatal o privada. Así, se pretende examinar la propagación de conocimientos agronómicos generados por expertos, pero también la difusión de experiencias empíricas llevadas adelante por los propios productores, en un contexto en el que la agricultura cerealera era la principal actividad económica de la región.
