A world that’s more expensive is starting to destroy demand – “A renewed spike in gas prices would see demand destruction become more widespread”

By David R Baker, Allison Smith, and Sheela Tobben 27 March 2022 (Bloomberg) – Prices for some of the world’s most pivotal products – foods, fuels, plastics, metals – are spiking beyond what many buyers can afford. That’s forcing consumers to cut back and, if the trend grows, may tip economies already buffeted by pandemic […]

FAO alarmed by uncertainty over wheat harvest in Ukraine – “War could seriously escalate food insecurity globally, when international food and input prices are already high and volatile”

By Marta Rullan 26 March 2022 ROME (EFE) – The planting of the next wheat season in Ukraine, “which could significantly affect world food insecurity, is still extremely uncertain” because of the war, the director general of the United Nations Food and Agriculture Organization (FAO), Qu Dongyu, told EFE, who was also very concerned about […]

The Amazon Rainforest is approaching a tipping point beyond which it would become savannah – “When it will be observable, it would likely be too late to stop it”

By Eric Shank 14 March 2022 (Salon) – A vast expanse of unique biological diversity hangs in the balance as the “lungs of the world” approach a tipping point from which there is no recovery. The Amazon Rainforest is losing its ability to regenerate, reported a peer-reviewed study, Monday, in Nature Climate Change. For 10% of all known species on […]

Brazil detects record Amazon deforestation in January and February 2022 – Forest destruction rate in 2021 was highest in ten years

By David Biller 11 March 2022 RIO DE JANEIRO (AP) – Detected deforestation in the Brazilian Amazon reached a record high for the month of February following a similar record the prior month. Satellite alerts of deforestation in February corresponded to 199 square kilometers (77 square miles), the highest indicator for that month in seven […]

FAO Food Price Index, January 1961 - February 2022. In February 2022, the FAO Food Price Index (FFPI), averaged 140.7 points, up 5.3 points (3.9 percent) from January and as much as 24.1 points (20.7 percent) above its level a year ago. This represents a new all-time high, exceeding the previous top of February 2011 by 3.1 points. The February rise was led by large increases in vegetable oil and dairy price sub-indices. Cereals and meat prices were also up, while the sugar price sub-index fell for the third consecutive month. Graphic: FAO

Russia invasion in “world’s breadbasket” threatens global food supply – Number of undernourished people could increase by 8 to 13 million in 2022-2023 – “Wars mean shortages, and shortages mean price hikes”

By Frances D’Emilio 11 March 2022 ROME (AP) – Poorer countries in northern Africa, Asia, and the Middle East that depend heavily on wheat imports risk suffering significant food insecurity because of Russia’s war in Ukraine, and the conflict is poised to drive up already soaring food prices in much of the world, the U.N. food agency […]

Wildfires ravage northern Argentina – “It never happened to us, we never lived something like this”

By Victor Caivano 21 February 2022 CORRIENTES, Argentina (AP) – Wildfires that have been ravaging northern Argentina for several weeks advanced relentlessly Sunday, although the light rains that began over the weekend gave some hope to firefighters. Corrientes province is the most affected area, where officials said at least eight separate fires continued to burn […]

Phytohormone pools affected by GBH, phosphate fertilizer and their combination in three crop species. Phytohormones, their precursors and metabolites; compounds that were analyzed in this study are indicated with abbreviations after the compound name. Additional compounds (without abbreviations) were added to show common pathway intermediates and to show biosynthetic origins of phytohormones. Chorismate derives from the shikimate pathway which includes the target site of glyphosate. By blocking the EPSPS enzyme, an essential biosynthetic step is corrupted, which is often shown to cause decreased biosynthesis of metabolites synthesized downstream of the shikimate pathway. Centrally placed hexahedron highlights the possible interactions between hormones also known as hormone crosstalk. Symbols (arrows and stops) besides and below metabolites (left side = oat, right = potato, and below = strawberry) indicate the effect of treatment (blue = phosphate, yellow = GBH, blue + yellow = phosphate + GBH) on each plant species corresponding to significances shown in Figure 2 (N = 40).

Glyphosate herbicide residues in soil affect hormone levels in crop plants – “Ubiquitous herbicide residues have multifaceted consequences by modulating the hormonal equilibrium of plants”

14 February 2022 (University of Turku) – A new study finds that glyphosate residues in soil affect phytohormones in aboveground plant parts. Academy of Finland funded postdoctoral researcher Dr. Benjamin Fuchs investigates the effects of herbicide residues in soil on plant physiology and chemical ecology of plant-insect interactions. Glyphosate-based herbicides are commonly used to kill […]
