Reducing Emissions from Deforestation and forest Degradation (REDD+) has emerged as a promising climate change mitigation mechanism in developing countries. In order to identify the enabling conditions for achieving progress in the implementation of an effective, efficient and equitable REDD+, this paper examines national policy settings in a comparative analysis across 13 countries with a focus on both institutional context and the actual setting of the policy arena. The evaluation of REDD+ revealed that countries across Africa, Asia and Latin America are showing some progress, but some face backlashes in realizing the necessary transformational change to tackle deforestation and forest degradation. A Qualitative Comparative Analysis (QCA) undertaken as part of the research project showed two enabling institutional configurations facilitating progress: (1) the presence of already initiated policy change; and (2) scarcity of forest resources combined with an absence of any effective forestry framework and policies. When these were analysed alongside policy arena conditions, the paper finds that the presence of powerful transformational coalitions combined with strong ownership and leadership, and performance-based funding, can both work as a strong incentive for achieving REDD+ goals.
Key policy insights
The positive push of already existing policy change, or the negative stress of resource scarcity together with lack of effective policies, represents institutional conditions that can support REDD+ progress.
Progress also requires the presence of powerful transformational coalitions and strong ownership and leadership. In the absence of these internal drivers, performance-based funding can work as a strong incentive.
When comparing three assessments (2012, 2014, 2016) of REDD+ enabling conditions, some progress in establishing processes of change can be observed over time; however, the overall fluctuation in progress of most countries reveals the difficulty in changing the deforestation trajectory away from business as usual.
Information on past and likely future trends in water temperature from different parts of the world is collated. The potential causes of trends in the thermal regimes of streams and rivers are many, but the existing database of water temperature information is inadequate to provide a global perspective on changes during the recent, let alone the more remote, past. Data from Europe suggest that warming of up to ca. 1°C in mean river temperatures has occurred during the 20th century, but that this trend has not been continuous, is distorted by extreme hydrological events, is not correlated with simple hydrometeorological factors and has been influenced by a variety of human activities. Predictive studies indicate that an accelerated rise in stream and river temperatures will occur during the next century as a consequence of global warming. However, forecasts must be tentative because future climatic conditions are uncertain and interactions between climate, hydrological and vegetation changes are complex. 相似文献
From 1985 to 1993, the mean summer temperature was 1.1°C above the long-term mean and the mean winter precipitation was 11% below the long-term mean at the eight Washington State Cascade Mountain weather stations. The effect of this climate fluctuation on glacier and alpine runoff has been examined in five North Cascade basins. From 1985 to 1993 the two basins with less than 1% glacier-covered area experienced mean 1 July to 30 September (late summer) runoff 36% below the long-term mean. The three moderately glaciated basins (3, 6 and 14% glaciated, respectively) experienced a 13% decline in late summer runoff for the same period. A significant change in late summer runoff has occurred in the North Cascades and this change is less pronounced in glacier basins. The cause of the change is decreased winter precipitation and earlier onset of spring melting of the alpine snowpack, followed by above average summer temperatures and an earlier summer melt of alpine snowpack. The smaller decrease in runoff in glacial basins is due to increased ablation and consequent glacier runoff due to high summer temperatures. However, glacier retreat is also reducing glacier runoff. 相似文献
