The 1912 Douglas-Fir Heredity Study is one of the first studies undertaken by the US Forest Service, and one of the first forest genetics studies in North America. The study considers provenance variation of 120 parent trees from 13 seed sources planted at five test sites in the Pacific Northwest. The unique, long-term nature of the study makes it valuable to revisit and consider its biological an...
On March 23, the United Nations Climate change secretariat announced that due to the novel coronavirus disease (COVID-19) it is going digital and embracing telecommuting and teleconferencing options in order to carry on with its work. The 17th meeting of the Adaptation Committee (AC 17), for instance, is now taking place virtually between March 24-27 as originally scheduled....
A severe insect pest epidemic may have changed the susceptibility of Scots pine (Pinus sylvestris) in Iceland to the pine woolly aphid. This could be the result of extreme selection pressure during the 1950s and 1960s, when the aphid damaged and killed the vast majority of Scots pines planted in Iceland. Scots pine was first introduced to Iceland early in the 20th century, with extensive plantings...
Several local authorities have included major tree planting initiatives as part of their climate declarations - but can we plant our way to carbon neutrality by 2030? 1st Vice President of the Directors of Environment, Economy, Planning & Transport (ADEPT) and Chair of the Local Adaptation Advisory Panel (LAAP) Nigel Riglar, discusses more....
GCF Board approves USD 169.7 million in funding for public and private sector adaptation and mitigation projects and programmes with a total value of USD 618.7 million. GCF Executive Director Yannick Glemarec expects an increase from an average of 30 to 60 projects per year to be reviewed, based on the level of the GCF’s first replenishment. GCF increases the size of its independent Technical Ad...
Climate change and its consequences have radically changed the way we view the world. We are all aware of how flimsy our products now are. The good old days of durable appliances and heavy-duty equipment and gadgets are but nostalgic memories of yesteryears....
While studies have suggested that climate change adaptation will require dynamic sets of knowledge types—scientific, technical, local, and tacit—about complex, interconnected problems across spatial and temporal scales, less attention has been directed to how these different ways of knowing might be used to transform specific urban knowledge systems that are currently in place, to align with d...
Under flooding or anoxia the newly initiated roots of swamp tupelo produce et hanol and lactio acid and oxidize their rhizosphere. Unflooded roots produce less ethanol than flood roots and do not oxidize their rhizosphere. Oxygen enters the stem via the lenticels and appears to be diffused or transported via the cortex or phloem. Flood roots have less suberization in the epidermis in the terminal ...
Moldova has become the fourth country that submitted its 2020 Nationally Determined Contribution, joining the Marshall Islands, Norway and Suriname. The country enhanced its NDC to 70% (unconditional) and up to 88% (conditional) reductions in GHG emissions in 2030 compared to 1990. Implementation of Moldova’s NDC requires meeting its technology, capacity building, and finance needs, with estimat...
This video, originally posted to the Chinese Wechat account 绿色时空, shows the making of a cute woven bamboo fish bowl. Have you tried it? Let us know in the comments The International Bamboo and Rattan Organisation, or INBAR, is an intergovernmental organisation dedicated to promoting the use of bamboo and rattan for inclusive, green development. We research and strengthen the global knowle...
<p>The ability of natural resource agencies to act before, during, and after outbreaks of conifer bark beetles (Coleoptera: Curculionidae) is important to ensure the continued provision of ecosystem services. Adaptive capacity refers to the capability of an agent or system to adapt to change, regardless of whether it is examined as an independent social or ecological entity, or as a coupled ...
