Keeping healthy could become more costly as climate change and water scarcity cause a huge drop in the global production of vegetables and legumes, scientists said Monday.

The amount of vegetables produced could fall by more than a third, especially in hot regions like southern Europe and swaths of Africa and South Asia, said researchers from the London School of Hygiene and Tropical Medicine.

By analyzing studies across 40 countries, with some dating as far back as 1975, they found that hikes in greenhouses gases, water scarcity and global temperatures lowered the amount of vegetables and legumes produced.

Such drastic changes could drive up the prices of vegetables, which would affect poorer communities the most, according to the study, which was published in the Proceedings of the National Academy of Sciences.

“If we take a ‘business as usual’ approach, environmental changes will substantially reduce the global availability of these important foods,” said Alan Dangour, a co-author of the paper, in a statement.

Scientists have warned that world temperatures are likely to rise by 2 degrees to 4.9 degrees Celsius this century compared with pre-industrial times.

This could lead to dangerous weather patterns — including more frequent and powerful droughts, floods and storms — increasing the pressure on agriculture.

Food production itself is a major contributor to climate change.

Agriculture, forestry and changes in land use together produce nearly a quarter of global greenhouse gas emissions, making them the second-largest emitter after the energy sector, said the United Nations Food and Agriculture Organization.

The volume of food transported around the world also is exacerbating global warming.

The global demand for food is expected to soar as the world’s population is projected to grow to 9.8 billion people by 2050, up from 7.6 billion today, according to the U.N.

Crops now take up 11 percent of the world’s land surface, and livestock grazing covers 26 percent of ice-free land, according to the Organization for Economic Cooperation and Development (OECD).

Farming accounts for about 70 percent of all water used globally, said the OECD.

Water scarcity already affects more than 40 percent of the world’s population, according to the U.N.

That number is expected to rise due to global warming, with one in four people projected to face chronic or recurring shortages by 2050, the U.N. said.

“Urgent action needs to be taken, including working to support the agriculture sector to increase its resilience to environmental changes,” said Dangour. “And this must be a priority for governments across the world.” (VOA)

Breast cells may behave menace by High Vitamin D

Higher levels of Vitamin D among women

Higher levels of Vitamin D among women may reduce their risk of developing breast cancer post menopause, claimed a new study.

The study found that women with blood levels of serum 25-hydroxyvitamin D (OH) — the main form of vitamin D in blood — above 60 ng/ml (nanograms per millilitre) had one-fifth the risk of breast cancer compared to those with less than 20 ng/ml.

 Vitamin D levels in blood were measured during study visits.

Thus, researchers from the University of California-San Diego determined that the minimum healthy level of 25(OH) in blood plasma should be 60 ng/ml, instead of the earlier recommended higher than the 20 ng/ml.

“Increasing Vitamin D blood levels substantially above 20 ng/ml appears to be important for the prevention of breast cancer,” said lead author Sharon McDonnell from GrassrootsHealth, a non-profit public health research organisation.

The study, published in the journal PLOS ONE, analysed data from two randomised clinical trials with 3,325 combined women and a prospective study involving 1,713 women with average age of 63.

Participants were free of cancer at enrollment and were followed for a mean period of four years. Vitamin D levels in blood were measured during study visits.

“This study was limited to postmenopausal breast cancer. Further research is needed on whether high 25(OH)D levels might prevent premenopausal breast cancer,” said Cedric F. Garland from UC-San Diego. (IANS.)
