- Description: Profit accumulation is one of the key benefits associated with market access. However, market access tend to be the major challenge to many smallholder farmers and that ends up influencing their profitability. Irrigation schemes became one of the coping mechanisms for such farmers whereby they work collectively with the aim of overcoming the various technical and institutional constraints they confront. This study examined how profitability is influenced by market participation of irrigation schemes by identifying the market structures used by irrigation schemes and describing the challenges encountered by smallholder irrigation scheme members who operate in those markets and assessing the profitability of the identified market. Primary data were collected using a comprehensive questionnaire made up of both open and closed ended questions. Data were collected from two irrigation schemes namely: Melani irrigation scheme (Alice – Raymond Mhlaba Local Municipality) and Zanyokhwe irrigation scheme (Keiskammahoek – Amahlathi Local Municipality). Multi-stage sampling procedure was employed to select 100 respondents. SPSS (version 22) and Microsoft Excel computer programmes were employed to conduct the wide range of descriptive and inferential analyses involved. Frequencies, percentages and means were used for the descriptive results to describe the general characteristics (example: gender, age, marital status and level of education) and socioeconomic features of the respondents. A regression model (Binary logistic model) was done to examine how profitability is influenced by market participation. Furthermore, Gross Margin Analysis was conducted to find out the profitability of the market structures used by these irrigation schemes. The descriptive results showed that there is a relationship between profitability and market participation of smallholder irrigation schemes in Eastern Cape Province of South Africa, by participate on markets this can improve the livelihood of farmers. The binary logistic regression model results revealed that there are five significant variables at different statistical levels. Age (10percent), years of schooling (1percent), distance to markets (1percent), farming experience (5percent) and the household income at (10percent) had a statistically significant influence on the market participation decision. These findings suggest that an improvement in each of the significant variables can significantly influence farmer market participation decisions. Furthermore, based on the results of the study, policy recommendations are suggested, including improving dissemination of market information to farmers, encouraging farmers to seek markets before production and encouraging farmers to add value to their produce. The Gross Margin Analysis that was performed showed that in Melani irrigation scheme farmers had positive gross margins and farmers in Zanyokhwe irrigation scheme had a negative gross margin. Therefore it can be concluded that the market that is available to Zanyokhwe irrigation scheme does not give good returns, suggesting a need for changing the market so as to ensure that farmers derive meaningful access. The study recommends the improvements to market participation through credit to low income farmers, formal training, market information, better price and tax policies for smallholder irrigation farming to ensure sustainable improvements in profitability of smallholder irrigation schemes.

- Description: The purpose of this study was to assess, on limited scale, the socio-economic and environmental impact of small-scale mining in the Sarah Baartman District Municipality, a municipality that is predominantly rural in nature and stricken by poverty. The topic of legal and illegal small-scale mining has received considerable attention from both the government and communities in recent years. At the heart of small-scale mining is enshrined the goals of creating employment and promoting the economic growth and development of the district. This study investigates the results of both a legal and an illegal mining operation in the municipality.

- Description: Thermoluminescence of synthetic quartz annealed at 1000 ºC for 10 minutes has been studied. The aim was to study mechanisms of thermoluminescence in annealed synthetic quartz and to discuss the results in terms of the physics of point defects. The sample was irradiated with a beta dose of 10 Gy of beta radiation and then heated at a linear heating rate of 1 ºC.s-1 up to 500 ºC. The thermoluminescence (TL) glow curve consists of three glow peaks. Peak I at 74 0C (main peak) with high intensity as compared to the other two peaks. Peak II at 144 ºC is more intense than peak III at 180 ºC. This study was on the main peak (MP) at 74 ºC and peak III at 180 ºC. Kinetic analysis was carried out to determine the trap depth E, frequency factor s and the order of kinetics b of both peaks using the initial rise, peak shape, variable heating rate, glow curve deconvolution and isothermal TL methods. The values of kinetic parameters obtained were around 0.7 to 1.0 eV for trap depth and in the interval of 108 to 1015 s-¹ for frequency factor for both peaks. The effect of heating rate from 0.5 to 5 ºC.s-¹ on the TL peak intensity and peak temperature was observed. Also the effect of thermal quenching was observed at high heating rates. Since the TL glow curve has overlapping TL peaks, the Tm-Tstop method from 54 ºC up to 64 ºC and E -Tstop methods were introduced where a first order single peak was observed. Phototransfered thermoluminescence (PTTL) was investigated and characterized by three peaks. First PTTL peak I at 72 ºC, peak II at 134 ºC and peak III at 176 ºC. Analysis was carried out on peaks I and III for the effect of dose dependence from 20-200 Gy. Thermal fading was observed on PTTL peaks I and III, after storage time of 30 minutes.
