Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

UFS to host one the most prestigious seminars in leadership

2004-09-28

The Business School of the University of the Free State (UFS) will be hosting the Central Region’s screening of the largest global satellite broadcast of the 2004 Living Leadership: Delivering Results the Right Way event.

The event, which will take place on 21 October 2004 from 09:00-16:30 at the Albert Wessels Auditorium on campus, will be up linked from Atlanta, Georgia, USA, and will be broadcasted via satellite to 95 cities in two countries.

“This is a once in a lifetime opportunity for leaders in the Central Region to gain exposure to the pioneers in the international leadership field,” said Prof Helena van Zyl, Director of the UFS’s School of Management.

The global satellite simulcast will bring together a powerful diverse group of the world’s leading business authorities. This includes Mr Donald Trump, chairman of The Trump Organisation; Mr Mikhail Gorbachev, Nobel Peace Prize Winner and former president of the Soviet Union; Mr Jim Collins, speaking on his recent best-seller, Good To Great; Mr Peter Drucker, father of management and author of The Effective Executive; Ms Rosabeth Moss Kanter, professor at Harvard Business School; Mr Ken Blanchard, best-selling author of The One Minute Manager; Mr John C Maxwell, best-selling author of The 21 Irrefutable Laws of Leadership and acclaimed speaker; Mr Russell Simmons, entrepreneur and co-founder of Def Jam Records and Mr Larry Bossidy, co-author of the best-seller, Execution: The Discipline of Getting Things Done.

According to Prof Van Zyl the Living Leadership global satellite broadcast will give attendants exclusive access to the Financial Mail’s Executive Panel. It will also give local executives and renowned leaders the opportunity to share their interpretation of leadership in practical, relevant terms.

Mr Jack Welch’s executive assistant and author of Managing Up, Ms Rosanne Badowski and Ms Caroline Kepcher, an executive vice president to Mr Donald Trump and a lead role on NBC’s hit show, The Apprentice, will join the panel with a special session.

Each of the cutting-edge insights shared by this gathering of world-class leadership authorities will deliver effective benchmarks which teams will use to shape their business outcomes.

The cost is R950,00 per person (group discount is also available) – this includes the receipt of two free issues of the Financial Mail. Tickets are available at Computicket.
