Water, Land and Ecosystems [SEP] inception
Water, Land and Ecosystems
Water, Land and Ecosystems is one of several new research programmes approved by the CGIAR during 2011 after an extensive period of consultation that began in 2009. This research programme will draw on the resources of 14 CGIAR and numerous external partners to provide a more integrated approach to research into managing natural resources. The aim of the research programme is to increase agricultural productivity while protecting the environment, so food security is ensured for most of humanity and that poverty becomes history. The five main strands to the
a front and a back, appeared by 555 Ma (million years ago).
The earliest complex land plants date back to around 850 Ma, from carbon isotopes in Precambrian rocks, while algae-like multicellular land plants are dated back even to about 1 billion years ago, although evidence suggests that microorganisms formed the earliest terrestrial ecosystems, at least 2.7 Ga. Microorganisms are thought to have paved the way for the inception of land plants in the Ordovician. Land plants were so successful that they are thought to have contributed to
