IPS – Worms, Termites, Microbes Offer Food Security | Inter Press Service | Ecology | Scoop.it
Worms, Termites, Microbes Offer Food Security - Worms and termites are not likely to win hearts and minds, but they, along with lichens and microbes, are vital to food security, say biodiversity specialists who attended this month’s United Nations... conference on the Convention on Biological Diversity (CBD) in this south Indian city.

orms, termites, lichens and soil microbes may well be the heroes of food production as without these species land-based biodiversity would collapse and food production cease,” Julia Marton-Lefevre, director-general of the International Union for Conservation of Nature, told IPS.“In this day’s fierce competition for political attention and funds, (preventing) land degradation is a tough sell,” said Marton-Lefevre. “It may be one of the most serious threats to global food production and biodiversity over the next few decades, affecting an estimated 1.5 billion (poor) people.

“Soil biodiversity may not be the most glamorous of our biodiversity, but it is nevertheless highly important,” she added.

Safeguarding the underlying ecological foundations that support food production, including biodiversity, will be central to feeding seven billion inhabitants, climbing to over nine billion by 2050, says the U.N. Environment Programme (UNEP) study ‘Avoiding Future Famines: Strengthening the Ecological Basis of Food Security through Sustainable Food System’ released in Hyderabad.

“Soil is not an empty container, as is thought by modern agriculturists; land is a living organism and has to be valued as such,” emphasised internationally known Indian environmentalist and activist Vandana Shiva.

Borrowing from Charles Darwin, Shiva said, earthworms create dams without concrete, increase air volume within soil by 30 percent and improve water retention capacity by 40 percent, increasing the life of soil.

“Unfortunately, we are valuing inefficient systems like chemical intensive monoculture, forgetting that value and benefit lie in securing the soil that provides everything for humanity; discarding natural farming that simultaneously provides grains, firewood and also fodder for cattle,” Shiva told IPS.

Shiva hit out at Indian policy saying it gave “billions of dollars as subsidy for chemical fertilisers, completely ignoring the fact that the solution to hunger and poverty lay in biodiversity promotion – that is being destroyed by chemical farming.”

A produção de alimentos tem que ser um procedimento muito bem pensado, temos que preservar o solo, do contrário não teremos mais como nos alimentar!

Climate Change May Bring Big Ecosystem Changes - NASA Jet Propulsion Laboratory

Climate Change May Bring Big Ecosystem Changes - NASA Jet Propulsion Laboratory | Ecology | Scoop.it
By 2100, climate change will bring big changes to Earth's ecosystems, with many plants and animals facing increasing competition for survival, finds a new NASA/Caltech study.

 

Researchers from NASA's Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth's plant life is likely to react over the next three centuries as Earth's climate changes in response to rising levels of human-produced greenhouse gases. Study results are published in the journal Climatic Change.

 

The model projections paint a portrait of increasing ecological change and stress in Earth's biosphere, with many plant and animal species facing increasing competition for survival, as well as significant species turnover, as some species invade areas occupied by other species. Most of Earth's land that is not covered by ice or desert is projected to undergo at least a 30 percent change in plant cover - changes that will require humans and animals to adapt and often relocate.
