Managing your farm with Fruitlook

We all know South African farmers operate within a challenging environment, where the short and long-term viability of an operation entails picking a path through a multitude of production pressures. Some of these include rising input costs; competition for scarce water resources; and the challenges associated with a changing climate. Fruitlook, an online remote-sensing platform, […]

Louis Loubser’s ‘Tree Hog’

Earlier this month I visited Louis Loubser’s farm just outside of Robertson in the Breede Valley. Louis is the man behind the ‘Tree Hog’ – a simple, but extremely effective invention that can bring about considerable reductions in on-farm water and energy use!

The Passion behind ‘Farmer Angus’

Angus McIntosh – the previous London-based finance professional turned livestock farmer. Not a ‘gewone’ farmer, but a razor sharp and enthusiastic farmer that has steadfastly plotted his course against the grain of convention. For those of you that don’t know, Angus is the man behind Spier’s pasture-raised livestock and the ‘Farmer Angus’ name.  

Agroecology – the who’s who

What is agroecology? Agroecology is defined as “the application of ecological concepts to the design and management of sustainable agro-ecosystems” (Silici, 2014). The principles of agroecology are increasingly gaining traction as a means to building agri system sustainability and resilience, reducing dependence on costly chemical inputs, and building productivity at the farm level through the […]

JDK’s interesting household recycling initiative!

Arguably the most important step to driving any environmental initiative is to change behaviour. As with recycling, it is simply difficult to increase recycling rates without increasing  the rate at which recyclables are collected at both the household and company levels, requiring a change in behaviour by both you and I. JD Kirsten, realising the […]

‘Nudging’ the way to change

Having recently read the book ‘Nudge’ by Richard Thaler and Cass Sunstein, I became intrigued by the potential for ‘nudge’ solutions to environmental challenges, some of which are described in the book.

Western Cape dam levels: 15% by April 2017?

Since the winter of 2014, the Western Cape region has been in the midst of a significant and worsening drought. The winter rains of 2015 and 2016 have done little to offer relief, and as of the beginning of November 2016, the City of Cape Town entered into Level 3 Water Restrictions, and the agricultural […]

The odds stacked against SA’s beekeepers

In South Africa, honeybees and their pollination services contribute an estimated R16 billion to the national GDP, of which approximately R10 billion is generated in the Western Cape (Engineering News 2015). With the changing profile of deciduous fruits, increases in vegetable production; and large increases in vegetable seed production and expansion of macadamia nut plantations, […]

SA’s Agri Exports: Understanding Brexit

On the 24th of June, 2016, David Cameron announced the surprising results of the UK’s Brexit referendum – the scales were tipped towards leaving the EU, sending global markets into turmoil. The GBP dropped to a 31-year low against the USD, and USD2 trillion were wiped off global markets. The rand slipped by 8% against […]

Water Footprint: Stone Fruit Project

In my post in April this year, I outlined the two different Water Footprint guidance standards, and explained the blue, green and grey water footprint components. Based on the Water Footprint Network’s (WFN) guidance standard, we developed a data collection and calculation tool in order to streamline the water footprint assessment process. These were piloted […]
