Policy opportunities to enhance the role of smallholder livestock systems in Limpopo Province of South Africa

Post-apartheid administrations in South Africa were faced with redressing the legacy of multifaceted poverty and social inequalities created by apartheid politics. The entrance of smallholder farmers into the mainstream economy became a government priority and policy aim. Institutional efforts in Limpopo Province provided infrastructure to establish poultry and vegetable producing enterprises. Very few livestock projects were funded. The success rate of institutional interventions was low. We argue that smallholder livestock systems offer policy opportunities to realise post-apartheid reform goals in the smallholder livestock sector. The premises are; there are more livestock in communal smallholder sector than in the commercial sector. This indicates there is a substantial level of natural, human and social capital existing within smallholder livestock systems. Secondly, commercial livestock systems are increasingly converted to game and wildlife enterprises necessitating imports of large numbers of livestock from Namibia to account for the shortfall in red-meat in South Africa. It is possible that the low off-take characterising smallholder livestock and the Cattle Complex Philosophy probably deterred past efforts to recognise the potential of smallholder livestock systems for rural and agricultural development. The Cattle Complex Philosophy claims that African smallholders have an attitudinal resistance to sell livestock. Data from a survey amongst 193 households in ten villages of Sekhukhune District of Limpopo Province illustrates that low livestock sales relates to the dysfunctional composition, sub-optimal reproductive potential and high calf mortality of smallholder herds. Conclusions and policy recommendations are offered.Keywords: Smallholder, Livestock, Limpopo Provinc

The effect of orbital decompression surgery on refraction and intraocular pressure in patients with thyroid orbitopathy

Purpose: To investigate the effect of orbital decompression surgery in thyroid orbitopathy (TO) on both refractive status and intraocular pressure (IOP). Patients and methods: A prospective, multicentre, consecutive audit of patients undergoing thyroid decompression surgery. Indications for surgery included cosmetically unacceptable proptosis or corneal exposure. Exclusion criteria included the following: previous orbital surgery, glaucoma, corneal disease, steroid use in the preceding 12 months, or an acute optic neuropathy. Automated refraction, keratometry, pachymetry, Hertel exophthalmometry, and IOP were recorded at 1 month pre- and 3 months postoperatively. IOP using the Tono-Pen (mean of three readings) was measured in the primary, upgaze, and downgaze positions. Results: Data were collected from 52 orbits of 33 patients (East Grinstead, New York, and Adelaide). There was no significant difference between pre- and postoperative data for sphere, cylinder, or central corneal thickness (CCT). The mean spherical equivalent was −0.43±1.49 D pre-operatively and −0.28±1.52 D postoperatively. The steepest meridian of corneal curvature was 93.1 degrees pre- and 94.2 degrees postoperatively, with no significant difference. Mean IOP significantly decreased when measuring by Goldmann applanation tonometry (GAT) (2.28 mm Hg, * P=0.001) and Tono-Pen (3.06 mm Hg, * P=<0.0001). IOP measured in upgaze was significantly greater than that in the primary position. Regression analysis between change in IOP and either Hertel exophthalmometry or the number of orbital walls decompressed was non-significant (*Student's t-test). Conclusion: Patients with TO undergoing orbital decompression had, on average, with-the-rule astigmatism not affected by orbital decompression surgery. IOP was significantly reduced by decompression surgery although no relationship between IOP and the degree of decompression was observed.JH Norris, JJ Ross, M Kazim, D Selva, and R Malhotr
