A planetary health diet: kind to your body, animals and the planet

We need to eat much less meat

By Jennifer Cole, Royal Holloway, University of London

It has long been clear that certain foods and dietary choices are not good for human health, but there is now increasing evidence that they can also be bad for the health of the planet. The recently published Food in the Anthropocene: EAT-Lancet Commission on healthy diets from sustainable food systems highlights that it may not be possible to feed a future population of 10 billion people a healthy diet within planetary boundaries unless we make significant changes to our diets and to the way food systems are managed. In particular, we need to eat much less meat, particularly red meat from grain-fed livestock.

What’s it like doing a PhD with CABI?

In this Q&A article we hear from three PhD students who have collectively spent over 11 years studying at the CABI Switzerland centre in Delémont working with scientists there to improve the monitoring and management of invasive species in Europe and Africa.

Find out from Judith Stahl, Benno Augustinus and Theo Linders about what they did, who they worked with and what’s in store after CABI.

The twelve pests of Christmas (trees)

The Invasives Blog

For many, December means celebrating Christmas and a central part of that is a Christmas tree. Evergreen trees have been used in celebration for centuries. The ancient Egyptians, Chinese, and Hebrews used evergreen trees, wreaths, and garlands to symbolize eternal life. Pagans worshiped trees, and Romans used evergreen wreaths during the festival of Saturnalia.

The trees commonly used as Christmas decorations come from the genus Picea which is made up of around 35 species of coniferous evergreen trees in the family Picaceae. Popular Christmas tree species include Balsam Fir, Douglas Fir, and Norway Spruce.

The modern-day Christmas tree is thought to have started in 16th century Germany when Christians brought decorated trees into their homes. The Christmas traditions we know today were shaped by the Victorians, when the first Christmas tree was brought from Germany to the British royal household by Prince Albert in the 1840s. These days, around

Parthenium weed and annual ragweed are closely related members of the Asteraceae, known for their high allergenicity. The detrimental effects on human health of the more temperate annual ragweed are very well known. However, those of the more tropical parthenium weed are less well known and in fact much more severe, affecting many tens of millions of people each year.

Tuning into radio to dispel myths

In Africa, many communities are still unaware of the key principles of science, whether they relate to diseases or natural phenomena.

Until the beginning of the 1980s, in the slums of my native Benin, I remember that when lightning, hitherto considered a manifestation of the wrath of Heviosso, the god of thunder, fell on residential areas, voodoo worshipers travelled in procession to retrieve the bodies of the victims, to atone for their sins.

Victims of lightning were indeed considered as sinners.

Giving garlic mustard the biocontrol treatment

In eastern North America a species of weed has become an aggressive invader. Garlic mustard (Alliaria petiolata) is one of the most rapidly increasing woodland invasive plant species, spreading across northeastern and midwestern USA and southeastern Canada at a rate of nearly 2,500 square miles per year.

The plant was most likely introduced to North America in the 19th century, taken from its native habitat of Eurasia by settlers for medicinal and culinary use. Although the crushed leaves and seeds of garlic mustard smell like cultivated garlic and have been used as flavouring in cooking for centuries, the plant actually belongs to the cabbage family.

The time is ripe for climate adaptation in agriculture

By Janny Vos, Director of Strategic Partnerships at CABI

I recently attended the launch of the Global Commission on Adaptation (GCA) in The Hague where the words of the CEO of the World Bank – Kristalina Georgieva – resonated strongly with my work as part of an organisation that aims to improve people’s lives worldwide by providing information and applying scientific expertise to solve problems in agriculture and the environment. In a nutshell, it’s all about working together as we aim to achieve the UN’s Sustainable Development Goals (SDGs).

Ms Georgieva said, “What is new is the scope, the speed and the scale at which we must work to adapt to climate change. And it is cost effective as the returns on investments will be high.” CABI’s primary interests are helping farmers to grow more and lose less to agricultural pests and diseases, and the ‘returns on investments’ are indeed ‘high’ – they’re ultimately about securing food and nutrition security for the world’s growing population.
