Dr Katlego Mashiane
Striving to make a difference in the field of biodiversity conservation, Dr Katlego Mashiane decided to pursue a PhD in Geography, focusing on the spatial modelling of grassland diversity and nutrients in subalpine environments. He received his PhD during the recent April graduation ceremonies on the Qwaqwa Campus.

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age. 

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park. 

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

Apocalypticism and mysticism have become two key areas of research that have converged to form the heart of contemporary spirituality. It was with this in mind that leading local and international Bible scholars were invited to a collaborative international conference jointly hosted by the UFS Faculty of Theology and Religion and Yale Divinity School, with the theme Apocalyptic Literature and Mysticism—Investigating a Turn in Recent Apocalyptic Research.

It is perhaps unknown to many that a number of the most profound thinkers, both of Judeo-Christian tradition and other religions in general, were mystics. Their lives and writings speak of a longing for an intimate relationship with God, reflecting on universal existential questions such as understanding our human existence, our creation, and ultimately, the meaning of life.

Apocalypticism, on the other hand, focuses on texts and prophecies describing how an alternative, future world might replace our existing one, a process often cataclysmic in nature, thus, like the mystics, also reflecting on the deeper foundations of human existence and our possible demise.

Traditionally, both have been misunderstood and controversial, but more recent research has revealed their formative role in religious discourses, with many scholars finding growing commonalities between apocalyptic and mystical texts. Moreover, these commonalities help to establish a better understanding of Judeo-Christian traditions, as well as other religions in general.

This hugely successful UFS collaborative effort, as well as others of its kind, contribute to the growth of theology as a discipline, with a positive impact on the broader religious community, the church, and society as a whole in the common desire for a just, equitable, and humane world.
