Mpho Twala – the girl with the land

The Bachelor of Community Development qualification offered on the Qwaqwa Campus develops young professionals who are able to work collaboratively with the community to come up with initiatives that build resilience and sustainability. Before obtaining their qualifications, students are required to identify community needs and to come up with viable ways to eradicate these.

It was during this period that Mpho Twala, a recent CommDev graduate, identified a once-thriving community vegetable garden that had been abandoned and subsequently stripped over the years. Further research led her to realise that the soil was still very fertile, and with a bit of work, could once again be revived to become an income-generating business. She received her qualification during the April graduations on the Qwaqwa Campus, but she did not stop there.

Bringing change to the community through vegetable farming

Twala, with no agricultural background, approached the locals for permission to revive the 1-ha garden into a community-owned vegetable garden. “The land has been uncultivated for more than a decade, and after conducting a needs analysis, I didn’t want to leave it like that, because I saw that if I worked with young people, this would help with the high unemployment rate among the youth in this area,” Twala said.

She says she was driven by bringing about change in her community, which she believes was inspired by her studies.

“I’ve always wanted to do something in my community, and CommDev taught me to see opportunities instead of challenges.”

The vegetable garden currently has 17 employees, 10 of whom are under the age of 35. They are currently harvesting cabbages, various forms of spinach, and white onion – all organic – for home consumption and community purchasing. They also occasionally sell to hawkers around Qwaqwa.

Twala dreams of expanding the garden, adding more crops, and ultimately reaching commercial level. “We are currently classified under subsistence farming – farming for home consumption and selling the surplus so that the project can remain operational. But with the right funding and support, we can grow bigger and better.”

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
