Quand les arbres sauvent des vies

Mais ce ne sont pas simplement les grandes forêts qui font la différence. Chaque arbre compte, et notamment ceux des zones urbaines. © Dustin M. Copenhagen Consensus Center. The following highlights have been determined using the recommendations provided in the assessment and perspective papers.

"The Copenhagen Consensus Center has just published the tenth set of research papers, this time focused on Biodiversity. In a series of new studies for the Copenhagen Consensus Center, Economists Anil Markandya, Luke Brander and Alistair McVittie argue that reducing the loss of coral reefs, wetlands and forests are worthwhile targets for the UN’s development agenda, each providing benefits to society greater than the costs of conservation. What's the smartest target? As reported in Huffington Post, stemming the loss of coral reefs by 50% will return at least $24 for every dollar spent. Coral reefs act as fishery hatcheries and fishing resources while storing abundant numbers of species. At the same time, coral reefs have large value for tourism. The costs of stemming coral reef loss are about $3 billion per year, but the total benefits likely run to at least $72 billion, producing the number of $24 dollars back for every dollar invested. Biodiversity Targets Benefit For Every Dollar Spent By 2030, stem the loss of coral reefs by 50% >$24 Reduce global forest loss by at least 50% $10 Reduce wetlands losses by 50% $10 By 2020, ecosystem resilience and the contribution of biodiversity to carbon stocks has been enhanced, through conservation and restoration, including restoration of at least 15 per cent of degraded ecosystems, thereby contributing to climate change mitigation and adaptation and to combating desertification. $7 By 2020, at least 17 per cent of terrestrial and inland water areas and 10 per cent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services are conserved through effectively and equitably managed, ecologically representative and well-connected systems of protected areas and other effective area–based conservation measures and integrated into the wider lands. $0.85 Interestingly, establishing environmental protected areas is not an effective way to go about preserving forests. Why? Because the costs of establishing and administering national parks are very high and the opportunity cost of land is enormous. You can read the all the reports at www.post2015consensus.com/biodiversity Here, Copenhagen Consensus Center has just released its latest research on Biodiversity targets for the Post-2015 development agenda. Anil Markandya, Scientific Director at Basque Centre for Climate Change writes the main report, peer-reviewed in perspective papers by Luke Brander, environmental economist affiliated to VU University Amsterdam and to Hong Kong University of Science and Technology and by Alistair McVittie, Environmental Economist at Scotland’s Rural College. Additionally, experts from the International Institute for Environment and Development present a viewpoint paper concerning Markandya’s analysis. PS. The Post-2015 Consensus project brings together 62 teams of economists with NGOs, international agencies and businesses to identify the targets with the greatest benefit-to-cost ratio for the UN's post-2015 development goals.

Within the focus area of Biodiversity the target that has the best benefit-to-cost ratio (BCR) is: By 2030, stem the loss of coral reefs by 50% which will return more than $24 for every dollar spent.

Nguiguis: Mango trees that grow without watering : Planting mango trees near piliostigma reticulatum shrubs (“nguiguis” in Ouolof) that will ensure water supply

It consists of first identifying a foot of piliostigma reticulatum, then probing the ground from the inside of the clump until there is a spot without roots. A hole the size of the tubes used in the nursery is dug at this spot. The mango plant is put in the hole. Planting can be done in the rainy season (from July 15th to August 15). Planting mango trees in clumps of nguiguis reduces the frequency of watering, as well as the amounts of water used.

This is well-known phenomenon called hydraulic redistribution occurs in the night. In what ways is this project unique and creative? Forêts. Reverdir le désert. Identification plantes. La mécanique des arbres. "Le monde du végétal est un monde qu'on n'apprécie pas assez.

Phénologie et changement climatique

L’étude minutieuse du rythme de vie des plantes d’années en années, appelée phénologie, en dit long sur le bouleversement météorologique et les dégâts qu’il peut produire. Un hiver trop doux ou au contraire trop froid, un été qui tarde à venir ou qui dure trop longtemps… Ces événements de plus en plus fréquents, conséquences directes du réchauffement climatique, semblent, pour l’instant, rester anecdotiques aux yeux de l’homme.

Les végétaux, en revanche, dont le développement dépend essentiellement des conditions météorologiques, font d’ores et déjà grises mines quand les températures perdent la boule.
