Forest Tenure

In recent years, private companies have acquired long-term leasehold titles to more than five million hectares of what was formerly customary land in Papua New Guinea (PNG), but hardly any of this land has been devoted to production of the four green commodities in which PNG might have some comparative advantage – sustainable palm oil, bio-ethanol, biodiversity and carbon credits.

Knowledge of the spatial distribution of forest types in tropical regions is important for implementation of Reducing Emissions from Deforestation and Forest Degradation (REDD), better understanding of the global carbon cycle, and optimal forest management. Frequent cloud cover in moist tropical regions poses challenges for using optical images to map and monitor forests.

SummaryThere are compelling reasons to encourage the employment of Indigenous Australians in the forestry sector. The benefits of, and constraints to, Indigenous employment in the sector were examined using a case study approach focused on Indigenous participation in ‘Operation Farm Clear’, an emergency response following Cyclone Larry in northern Queensland in 2006.

Land-use emissions accompanying biomass loss, change in soil organic carbon (ΔSOC) and decomposing wood-products, were comparable with fossil fuel emissions in the late 20th century. We examine the rates, magnitudes and uncertainties for major carbon (C) fluxes for rangelands due to commercial grazing and climate change in Australia.

Abstract.

Global conservation discourses and practices increasingly rely on market-based solutions to fulfill the dual objective of forest conservation and economic development.

The practice of raising cattle in the Amazon has been connected to deforestation, which has been especially intense in the Eastern Amazonian state of Pará that contained 23% of new rural settlements before 2008. The settlements were part of a program of land reform that allowed farmers to receive public credit.

Summary There are compelling reasons to encourage the employment of Indigenous Australians in the forestry sector. The benefits of, and constraints to, Indigenous employment in the sector were examined using a case study approach focused on Indigenous participation in ‘Operation Farm Clear’, an emergency response following Cyclone Larry in northern Queensland in 2006.

A reconstruction of land use changes and the implications thereof for landslide occurrence on critical slopes of Mount Elgon in Eastern Uganda were undertaken. Aerial photographs taken in 1960 formed the benchmark for the analysis of respective land use changes between 1995 and 2006, using 30m Landsat TM and 20m SPOT MS images.

Payment for ecosystem services (PES) has been widely promoted as an effective and efficient model for conservation; however, few studies have empirically examined how the market-based approach interacts with farmer's decision-making processes and their abilities to sustain new conservation practices.

It is necessary to estimate the area of afforestation and deforestation in New Zealand, since 1990, to meet reporting obligations under the Kyoto Protocol. We describe a method for national mapping of forest change that achieves high accuracy, but only requires moderate effort.

The implementation of an international programme for reducing carbon emissions from deforestation and degradation (REDD) can help to mitigate climate change and bring numerous benefits to environmental conservation. Information on land change modelling and carbon mapping can contribute to quantify future carbon emissions from deforestation.
