Since the time of the ancient Egyptians vultures have been revered in Africa for having the ability to see the future, but also regarded as greedy, dirty scavengers. All of our vulture species are critically endangered, so this week we will explore the threats and conservation strategies for our vultures.

We rely on complex ecosystems for our various, basic needs, but these systems are unpredictable. So how do we organize ourselves to ensure that current and future generations can meet their needs?

The ecosystems that we rely on are complex systems, supporting diverse groups of people with different needs, such as food, water, fuel and fiber. So how do we build a resilient, sustainable ecosystem?

Firewood makes up a large portion of the energy needs in Zimbabwe, and much of this is used for cooking food. So my guest, Robin Poles, discusses the design of wood stoves for a healthier kitchen and ecosystem.

Have you ever deliberately spent time outdoors in a time of crisis? Perhaps gardening, walking or playing sport? This is known as urgent biophilia. My guest, Rebecca MacKinnon, has looked into this phenomenon in some detail. We will discuss a small study that she set up to understand why people need nature when things get challenging.

We often hear that trees are being felled at an alarming rate, but how can we measure that rate of loss? One tool is remote sensing, using images taken by satellites to see changes in vegetation cover over time. So this week we look at how satellites and computers enable us to monitor losses and also the progress in reforestation projects.

Woodlands are a very important part of the economy in Zimbabwe, providing the energy needs of many households and businesses, resulting in widespread deforestation. One way to address this is by replanting trees, but reforestation projects often fail. So today we will discuss why projects fail and how to make an effective reforestation strategy.

Water supply is a very important issue globally, but particularly in Zimbabwe where access clean water is limited. So this week's episode is on wetlands; Their types, their functions and what we can do to conserve them
