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 receives research grant focusing on enablement of non-profit organisations

2011-01-20

Prof. Mabel Erasmus

The University of the Free State (UFS) has received a research grant to the value of R1,1 million from the National Research Foundation (NRF) to conduct research on community engagement, with the emphasis on knowledge as enablement – a Non-Profit Organisation (NPO) focus.

This was the first time the NRF had requested applications for research with a focus on community engagement (CE). With the grant, the UFS has become one of the first recipients of a research grant that focuses on community engagement.

The overarching research question that will be dealt with is how Higher Education Institutions (HEI) and the NPO sector can establish long-term, research-based collaborative engagements that will be mutually empowering and enabling through joint, reciprocal knowledge-based activities and capacity building.

The contention that this proposal is based on, is that HEIs have limited knowledge of the NPO sector and thus are unable to be fully responsive to the challenges that NPOs face. What is more, it is very likely that staff and students from HEIs do not have an adequate grasp of the experiential understanding, contextual community knowledge and practical know-how that NPO practitioners have, and hence do not appreciate the crucial contributions that they can make with regard to meaning-making processes aimed at improving some of the harsh South African realities.

According to Prof. Mabel Erasmus, Associate Professor and Head of the university’s Division: Service Learning, which submitted the research proposal to the NRF and is the grant-holder, the university would like the information generated by the research to be beneficial to both HEIs and the NPOs. “Knowledge regarding NPOs, specifically their challenges and information about what they are doing, will be invaluable to HEIs. At the same time, the research must benefit the NPOs with knowledge to improve their practice and strengthen their functioning.

“The research will take place in close collaboration with the NPOs, as their inputs are crucial. The research will thus not be ‘about’ them but ‘with’ them.”

“We do not want to send our students for community-based education or as volunteers to NPOs year after year and it does not mean as much to them as these organisations would hope for. With the research process we would like to strengthen NPOs, to build their capacity and give them our whole-hearted cooperation,” she said.

Funding received from the grant will be applied over a period of three years. Except for the study grants for five Ph.D. students and four master’s students, the grant will further make provision for a number of workshops, a local conference, a publication and presentations at international conferences on this matter. The research team of 22 persons includes academics from other HEIs such as the Central University of Technology, University of Zululand, University of Johannesburg and Monash SA. Several staff members of NPOs also form part of the team, including REACH (Bfn), Childline (FS) and others.

Prof. Erasmus said that the UFS was one of a few institutions that were currently conducting research to this extent on the link between the NPO sector and HEIs within the field of community engagement.
