Tackle invasive species to restore degraded landscapes
By Gilbert Nakweya Reblogged from SciDev.Net Invasive alien species should not be used in restoring degraded landscapes as their costs outweigh their benefits, experts say. Invasive alien species, according to the Convention on Biological Diversity, are plants, animals and other organisms that are non-native to an ecosystem, and may adversely affect human health and the…
Invasive alien plants, land degradation and restoration
Reblogged from Global Landscapes Forum Invasive alien plants contribute to land degradation by forming vast unproductive monocultures. These invasions have a negative impact on biodiversity, water resources, crop and pasture production, human and animal health, and as such undermine Africa’s ability to achieve its Sustainable Development Goals. Landscapes degraded as a result of unsustainable land-use…
Tiny mite could prove a ‘mighty’ weapon in the fight against one of the UK’s most invasive weeds
CABI scientists are stepping up the fight against one of the UK’s most invasive non-native aquatic weeds. Approval has been given for the release of a novel biological control agent – the mite, Aculuscrassulae – to assess its ability in the real-world environment to suppress Australian swamp stonecrop (Crassula helmsii), also known as New Zealand pigmyweed. This…
Scientists discover new crop-destroying Armyworm is now “spreading rapidly” in Africa
New research announced today by scientists at CABI confirms that a recently introduced crop-destroying armyworm caterpillar is now spreading rapidly across Mainland Africa and could spread to tropical Asia and the Mediterranean in the next few years, becoming a major threat to agricultural trade worldwide.
Invasive alien species (IAS) threaten livelihoods and biodiversity globally
Invasions from non-native plants, animals and pathogens threaten the economies of the world’s poorest nations, according to a new study. The study, published in Nature Communications (‘Global threats from invasive alien species in the twenty-first century and national response capacities’) found that one-sixth of the world’s land is highly vulnerable to invasion, including substantial areas…
New European Union IAS Regulation
Invasive alien species are a major threat worldwide, impacting upon millions of livelihoods and threatening biodiversity. The situation is worsening, due in no small part to increased global trade and transport. The economic costs of IAS can be vast: worldwide, invasive species are estimated to cost US$1.4 trillion per year – close to 5% of global…
