In South Africa, communal and/or emerging farmers’ rangeland condition and grazing capacities deteriorate, because grazing capacity is usually over-estimated due to lack of knowledge on veld and livestock production system by the farmers. Woody plants has encroached in the arid and semi-arid savannas and grasslands biomes many parts of world, including in southern Africa. This causes challenges to farm owners due to its negative effects on the herbaceous plant material, which offers a substantial part of forage for livestock production. Although the consequences of deteriorating rangeland condition on livestock production is understood, there is limited research on the impact of land ownership on rangeland condition. Furthermore, knowledge on how farmers manages their livestock and rangelands.
The objectives were to document the knowledge of emerging livestock farmers on livestock-rangeland management practices, and to determine the effects of land ownership and practices on rangeland condition. Firstly, we hypothesize that, emerging livestock farmers unknowingly manages livestock in isolation from their rangelands, and secondly, rangeland in private owned lands are relatively in good conditions compared to communal and leased lands.
Fifty (50) emerging livestock farmers (i.e. ruminants) in different vegetation types and district municipalities of the Gauteng province were selected using a snowball procedure. To investigate the knowledge of emerging farmers on livestock - rangeland management practices, the farmers were asked questions about their 1) demographic information, 2) livestock management practices and 3) rangeland management practices. To test the differences in farmers’ demographic profiles, Chi-square statistics was employed. To determine the effects of land ownership on rangeland condition of the selected farms, rangeland condition among three land ownership types was compared using ANOVA, and the relations between veld condition score (%) and herbaceous biomass production (kg DM/ha) was tested using Pearson’s correlation analysis
The results revealed that, the emerging livestock farmer are dominated by males (68 %) compared to female (32%). Majority (66%) of the farmers are old aged (> 50 years) compared to middle aged (30% (31 – 50 years)) and young (< 30 years) farmers (4%). Farmers who did not receive any agricultural training were higher (74%) than farmers who had prior training (26%). Sixty-three percent of the farmers had knowledge and understanding of breeding and calving seasons of their livestock, with only 27% having no knowledge and understanding of breeding and calving seasons of their animals. Eighty-three percent of the farmers keep mixed livestock (cattle, sheep and goats) species and 17% only keep cattle. The mean cattle herd sizes were significantly lower 8.2 ± 7.16 compared to goats and sheep (15.5 ±11.2). Feed shortage was the major constrain to livestock production (46%) compared to diseases (26%), marketing (14%), stock theft (8%) and other (6%) constrains. Sixty-three percent of the farmers had knowledge and understanding of breeding and calving seasons of their livestock, with only 27% having no knowledge and understanding. Eighty-three percent of the farmers keep mixed livestock (cattle, sheep and goats) species and 17% only keep cattle. All of the farmers indicated that they did not conduct rangeland condition assessment (mainly due to lack of knowledge). All farmers did not have fodder conservation plan for their farms and highlighted that during dry season, forage is scarce for their animals. Majority (58%) of the farmers relay on government-drought relief programme compared to those who were supplementing (20%), selling their animals (14%) and those with no drought coping strategy (8%). v
Vegetation was assessed using nearest plant technique. In total, 28 grass species were identified during field survey, of which n=23, n=4 and n=2 were perennials, annuals and short-lived perennial, respectively. The most commonly observed and very palatable grass species, Digitaria eriantha had the highest frequency on private lands (n=92 and the lowest on communal lands (n=51). There were no significance difference in grass species richness and basal cover among land ownership types (P > 0.05). There were significant differences in veld condition score, large stock units, grazing capacity and herbaceous biomass production among land ownership types (P < 0.05). Private lands had a significantly higher veld condition score (69.63%) than leased (56.07%) and communal lands (52.55%). The herbaceous biomass production was positively correlated to the veld condition score (r = 0.159; P<0.005). The outcomes of this study show that emerging livestock farmers in Gauteng province have little understanding of rangeland-livestock management practices. The current results further indicated that poor grazing practices such as overgrazing might be common on leased and communal lands due to farmers’ lack of knowledge on rangeland management practices. This may lead to rangeland degradation thus negatively affecting livestock production and the livelihood of farmers who rely on farming as a source of income. / Agriculture, Animal Health and Human Ecology / M.
