water use – The Green Tau

31st January 2025

Sustainable use of land resource also extends to how we use finite water resources. Some crops use particularly large amounts of water – eg blueberries, strawberries – and realistically shouldn’t be grown in areas where water is a scarce resource and should be reserved for critical crops and drinking/ sanitation. In Peru blueberries are grown in areas where local crops are at risk from lack of water. Almond trees need more water than pistachios and in Spain farmers are switching from almonds to pistachios in face of the increasing prevalence of droughts.

At the same time, such water rich-crops are often vulnerable to damage – strawberries and blueberries are very susceptible to damage and often have a short shelf-life.

As consumers we can avoid buying foods that are grown with the unsustainable use of water.

For a change of emphasis, I plan over the next few weeks to look at some of the things we do as a household to live more sustainably. Maybe what we do might prompt some thoughts for you, and maybe you will have some ideas to share as well.

I follow a vegan diet and as I am the main cook, all home cooking is vegan!

Vegan diets have a smaller carbon footprint and cause less damage to the climate – research suggests somewhere in the region of 75% less! The food grown for vegan diets uses less water and less land – largely because of the significant amounts of land and water needed to grow feed for farm animals. Needing less land has two benefits – first the ability to grow more food for a growing population, and second the ability to set aside more farm land for rewilding and restoring levels of biodiversity.

I also chose a vegan diet on the grounds of animal welfare. Even eating a vegetarian diet involves the slaughter of young animals – principally male chicks and male calves – as well as the likelihood that the females will have stressful lives of repeated birthing.

I can see that for some people raising low intensity livestock can be a key part of a farm’s ecology, and that eating small amounts of meat and dairy would be consistent with that.
