The high water intake and wastewater discharge of slaughterhouses have been a concern for many years. One neglected factor in previous research is allocating the water footprint (WF) to beef production’s different products and by-products. The objective of this article was to estimate the WF of different cattle breeds at a slaughterhouse and cutting plant and allocate it according to the different cuts (products) and by-products of beef based on the value fraction of each. The results indicated a negative relationship between the carcass weight and the processing WF when the different breeds were compared. Regarding a specific cut of beef, a kilogram of rib eye from the heaviest breed had a processing WF of 614.57 L/kg, compared to the 919.91 L/kg for the rib eye of the lightest breed. A comparison of the different cuts indicated that high-value cuts had higher WFs than low-value cuts. The difference between a kilogram of rib eye and flank was 426.26 L/kg for the heaviest breed and 637.86 L/kg for the lightest breed. An option to reduce the processing WF of beef is to lessen the WF by slaughtering heavier animals. This will require no extra investment from the slaughterhouse. At the same time, the returns should increase as the average production inputs per kilogram of output (carcass) should reduce, as the slaughterhouse will process more kilograms.

Recurring agricultural droughts are of concern to smallholder livestock farmers in Sub-Saharan Africa. This study determined the impact of agricultural drought resilience on smallholder livestock farming households’ welfare in the Frances Baard District Municipality (FBDM), in Northern Cape Province of South Africa. Interviews, more specifically survey interviews, were conducted with 207 smallholder livestock farmers. We used compensation variation, resilience index and linear regression models to analyse the data. The findings indicate that smallholder farmers who received drought relief support saw an improvement in their welfare. However, the welfare improvements varied across respondents and different gender categories, with males having higher welfare improvements relative to females. The study also found that economic capital, social capital, human capital and natural capital substantially affected the welfare of smallholder farmers. Furthermore, the study revealed that the smallholder farmers had a moderate agricultural drought resilience index, but low natural resilience capital. The study recommends that governments and non-governmental policymakers aiming to improve the welfare of smallholder farmers should focus on building their economic, social, human and capital resource bases. In this way, the smallholder farmers will be resilient in a time of climatic shock.

Using the current state of life cycle assessment (LCA), carbon and water footprinting, and EPDs in South Africa, this work explores the challenges and opportunities for scholarly development in these areas in the country. Being a relatively small LCA community in South Africa, academics, consultants, and other stakeholders were approached to provide lists of known studies, with further reports, that may have been missed, obtained through internet searches. Information was collated on database development, capacity building, and other aspects and presented here in a single paper. While the authors are aware of companies working on LCA and related studies, hidden in confidential reports, we were able to find 27 LCA, 17 water and 12 carbon footprinting, and 10 EPD studies. Although these studies have potential advantages for policymaking and business, their number, implementation, and impact remain limited. While previously seen as an academic exercise, life cycle thinking has been adopted by industry, private consultants, and the South African National Cleaner Production Centre (NCPC-SA), among others. Growing interest has led to the creation of several training courses available at academic institutes, the NCPC-SA, and consulting firms, ranging from the basic understanding to advanced use of software packages and modeling techniques. The development of a national LCI database and further exposure and opportunity for LCA studies are important steps to hopefully spur LCA in Southern Africa in the future.

Beef has been identified as the farm animal product with the largest total water footprint in previous research, although various concerns have been raised regarding the top-down analyses approach followed in these studies. The objective of this study was to estimate the water footprint of weaned calves and culled cows from seven different beef breeds by applying a revised water footprint analyses approach. A bottom-up approach was followed to provide a true representation of the production system, and the water footprint of the production system, with the estimated water footprint for the system being allocated to weaned calves and culled cows according to the value factor of each. The results show that there are prominent differences between the seven breeds in terms of their respective water footprints per kilogram weaned calf, even though the total water footprint per herd for each breed revealed little variation between the breeds. There is a 45% difference between the breed with the lowest and the breed with the highest water footprint per kg calf. This knowledge can be applied by both water users (primary producers) and policy formulators to assist in the optimal use of fresh water for beef production.

Integrating best management practices and improving the technical efficiency of smallholder maize farmers is critical in raising overall agricultural output. However, there is not much information, besides marginalization and high rehabilitation and maintenance costs, which adequately explains why productivity of smallholder irrigation farmers drop at very high rates. Therefore, this study measured technical efficiency, identified factors affecting technical efficiency, and identified best management practices adopted by smallholder maize irrigation farmers at Tokwane-Ngundu (Zimbabwe). The Data Envelopment Analysis, Double Bootstrap Approach in a Principal Component Regression was used. Primary data were gathered using a questionnaire. Empirical results revealed that the mean technical efficiency of the respondents was 77%, which indicated a potential for them to increase their efficiency by 30%. The factors that increased technical efficiency included human capital, extension contacts and compliance with best management practices. The policy implication of this study is the need for robust group incentive schemes to promote farmer-to-farmer skills transfer to boost the technical efficiency of smallholder maize irrigation farmers in Zimbabwe.

The feed conversion rate is one of the most important determinants of the water footprint (WF) of beef and is known to vary between different cattle breeds. The objective of this study was to estimate the WF of industrially finished calves of seven different cattle breeds on two different feeding regimes: normal pre-determined feeding period (NPFP) and profit-maximising feeding period (PMFP). Data were collected by finishing 35 calves of each of the seven breeds in a feedlot. Green, blue and grey WFs were estimated for the different feeding regimes, and a feedlot simulation provided the effect of the different feeding regimes on the water footprint, financial margin and the water footprint per rand of margin. The results indicated that the water footprint differed notably between breeds on the same feeding regime, as well as between the feeding regimes. While the PMFP had a 1% higher water footprint per year in a typical feedlot than the NPFP, the financial margin was 33% more, resulting in a 24% decrease in the water footprint per South African rand of margin. The contributions of green, blue and grey water to the total WF were 91.5%, 2.5% and 6%, respectively, irrespective of breed or feeding regime.

The purpose of the paper is to determine the influence of different factors used by a formal credit institution to evaluate loan applications in the agricultural sector. The research attempts to capture the actual factors considered by credit institutions rather than the traditional factors found in literature. Loan applications from 128 farmers, predominantly commercial farmers, were obtained from a credit institution with branches situated in various provinces of South Africa. Data consisted of loan application information which is broader than the financial information normally obtained in credit research, and the final decision of the credit provider. Principal component logistic regression was used to investigate the likeliness with which loan application variables influence the outcome of the loan application. Results indicate that loan applications that are more likely to be successful are older more experienced farmers, who can provide sufficient collateral, have more years of business with the credit provider, have an acceptable credit history, request smaller loan amounts, have lower interest expense ratio, higher production cost ratios, and have diversification strategies. This paper contributes to knowledge on information used by financial credit providers (institutions) in classifying agricultural loan applications as successful as guided by actual factors used in credit decision making by the credit provider.

There is an urgent need for the development of environmentally sustainable products market in developing economies, particularly in South Africa due to increasing ecological externalities and risk. We use a stated preference method to examine the heterogeneous demand for ecologically sustainable products. A hybrid latent class model was employed to account for the inclusion of attitudinal information, potential endogeneity and measurement errors. The empirical estimates demonstrate that majority of the respondents attach significant monetary values to meat products with minimal environmental impacts in terms of water and carbon footprint values. We found three heterogeneous consumer segments, with distinct utilities and monetary values attached to water and carbon footprint attributes. Furthermore, the findings show that consumers’ choice and valuation of the sustainability attributes significantly relate to their fundamental attitudes towards the environment and sustainable practices, as well as their knowledge towards environmental sustainability. The use of economic incentives as a mechanism to ensure environmental sustainability is feasible in South Africa. The empirical framework used offered a theoretical advantage in terms of endogeneity bias and measurement error, relative to the traditional latent class model.

In this article, we used a hybrid latent class model and choice experimental data to examine the choices of consumers regarding water and carbon footprint attributes. The findings indicate that a significant proportion of middle- to upper-class consumers are generally willing to pay higher premiums for a reduction in both water usage and carbon emission in agricultural production, displayed through water and carbon footprint labelling. There exist heterogeneous preferences for water and carbon footprint sustainability attributes, with some being environmental sustainability activists and water sustainability advocates, while others are conservatives regarding environmentally sustainable products. About 86 per cent of the middle-class to upper-class respondents attaches a higher monetary value to low water usage relative to low carbon emissions. The preferences for ecologically sustainable product attributes differ significantly as a function of respondents’ underlying attitudes towards environmental degradation and sustainability, socioeconomic characteristics and awareness of water scarcity situation locally. The findings contribute to the current debate on the possibility of using environmentally sustainable production and ecological footprint labelling to address the problem of ecological externalities in the food and agricultural sector.

Efficient and wise management of freshwater resources in South Africa has become critical because of the alarming freshwater scarceness. The situation requires a thorough examination of how water is utilized across various departments that use water. This paper reports on an examination of the water footprint and economic water productivities of the wheat-bread value chain. The assessment methodology of the Water Footprint Network was employed. The findings reveal that 954.07 m3 and 1026.07 m3 of water are utilized in the production of a ton of wheat flour in Bainsvlei and Clovelly in South Africa. The average water footprint for wheat bread was 954.53 m3 per ton in Bainsvlei and 1026.53 m3 per ton in Clovelly. More than 99% of the water is used in producing the grain at the farm level. The processing stage of the value chain uses less than 1% of the total water footprint. About 80% of all the water utilised along the wheat bread value chain is attributed to blue water. The findings revealed a significant shift from green water consumption to higher blue water use, and this is a major concern for water users and stakeholders along the wheat-bread value chain, given that blue water is becoming scarce in South Africa. The groundwater contributes about 34% and 42% of the average total water footprint of wheat at the farm level in Clovelly and Bainsvlei, respectively, suggesting the need to have an idea of the contribution of groundwater in water footprint evaluation and water management decision of farmers. This insight will aid in minimizing irrigation water use and pressure on groundwater resources. A total of ZAR 4.27 is obtained for every m3 of water utilized along the wheat-bread value chain. Water footprint assessment has moved away from sole indicator assessment, as a deeper awareness of and insight into the productive use of water at different stages has become vital for policy. To make a correct judgment and to assess the efficient and wise use of water, there is a need for catchment- or region-specific water footprint benchmarks, given that water footprint estimates and economic water productivities vary from one geographical area to another.

Approximately 75 per cent of South Africa’s beef is finished by feedlots. The profitability of the beef industry remains under pressure due to various external factors. Previous research has shown that many factors influence feedlot performance and profitability. It is, however, very difficult to judge an animal’s inherit feedlot performance before it enters the feedlot. The aim of this study was to explore the relationship between the animal traits of Santa Gertrudis bulls and the feedlot profitability of these bulls. Analysed traits included the sheath score, capacity score and build score as high scores for these traits are believed to be associated with better feedlot performance. The data for this study was collected from 48 Santa Gertrudis bull calves. The profitability of feeding cattle was expressed as the Total Margin (TM) and Feed Margin (FM). Given the nature of the dependant variables, Ordinary Least Squared regressions were used for the analyses with TM and FM as dependent variables. Results show that although both models were significant, the sheath score was the only individual trait that proved to be significantly correlated with both TM and FM. Sheath score proved to be negatively correlated with TM and FM while it was expected, through popular belief, to be positively correlated. This implies that animals with lower sheath scores, thus with sheaths closer to their bodies, perform better in the feedlot and may affect the TM and FM positively. The magnitude of this trait still remains under question and further research is required.

We evaluate the impact of the Generalized System of Preferences (GSP) scheme on horticultural exports from Kenya, Tanzania and Uganda to the European Union (EU). The preference margin, computed as the difference between trade-weighted Most Favoured Nation’s rate and the ad valorem equivalents(, is used as a proxy for the GSP scheme. The zero-inflated Poisson estimator is used to control for overdispersion and excess zero trade flows, while time-invariant effects control for heterogeneity. The findings suggest that the EU-GSP scheme promotes bean exports from the three East African states as well as pepper from Uganda. Conversely, the results suggest that the scheme seems not to enhance export of asparagus from Kenya, vegetables from Tanzania and bananas from Uganda to the EU.

Climate change and its impact on already scarce water resources are of global importance, but even more so for water scarce countries. Apart from the effect of climate change on water supply, the chill unit requirement of deciduous fruit crops is also expected to be affected. Although research on crop water use has been undertaken, researchers have not taken the future climate into consideration. They also have focused on increasing temperatures but failed to relate temperature to chill unit accumulation, especially in South Africa. With a view of helping farmers to adapt to climate change, in this study we provide information that will assist farmers in their decision-making process for adaptation and in the selection of appropriate cultivars of deciduous fruits. Crop water use and chill unit requirements are modelled for the present and future climate. Results show that, irrespective of the irrigation system employed, climate change has led to increases in crop water use. Water use with the drip irrigation system was lower than with sprinkler irrigation as a result of efficiency differences in the irrigation technologies. It was also confirmed that the accumulated chill units will decrease in the future as a consequence of climate change. In order to remain in production, farmers need to adapt to climate change stress by putting in place water resources and crop management plans. Thus, producers must be furnished with a variety of adaptation or management strategies to overcome the impact of climate change.

The global water scarcity situation is a major issue of concern to sustainable development and requires detailed assessment of water footprints and water productivities in all sectors of the economy. This paper has analysed economic water productivities along the dairy value chain in South Africa. The findings reveal that the value added to milk and water as it moves along the value chain varies from stage to stage; with the highest value being attained at the processing level, followed by the retail and farm gate levels, respectively. Milk production in South Africa is economically efficient in terms of water use. Feed production accounts for about 98.02% of the total water footprint of milk with 3.3% protein and 4% fat. Feed production is economically efficient in terms of cost and water use. Value addition to milk and economic productivity of water are influenced by packaging design. Not all economically water productive feed products are significant contributors to milk yield. Future ecological footprint assessments should take into account the value added to output products and economic water productivities along the products' value chain, rather than relying only on water footprint estimates.

Climate change and its impact on already scarce water resources are important issues being publicly debated in the world today. Water resources are of more concern because changes in the water supply will affect the water availability for household use, agricultural practices, and for the vast industrial water demand. With the view of helping famers to adapt to climate change, the Ceres Dynamic Integrated Model was developed to simulate the impacts and evaluate different adaptation strategies thereof. The results show that a substantial change can be expected in the profile of the farming community. However, with adaptation the welfare of the farmers can be improved. Depending on the availability of funds to make farm dams available for farmers, access to farm dam capacity and winter water allocations as well as increasing water use efficiency are potential adaptation options for the farmers. Improved water management practices that increase the productivity of irrigation water use may provide a significant adaptation potential under future climate. Therefore, farmers must be equipped with a collection of management or adaptation tools to overcome slight climatic differences.

Aim:The main objective of this study was to explore the relationship between the entrepreneurial competencies of farmers and their financial performance. Setting: The study was conducted in South Africa among farmer clients of a commercial financial organisation.Methods: The financial performance of the farmers was calculated by means of financial ratios which were used to compile a single performance indicator: operating efficiency. The operating efficiency indicator was calculated using a financial-based data envelopment analysis. An entrepreneurial competencies instrument was used to measure the entrepreneurial competencies of the farmers. Ordinary least squares regression was used within the principal component regression framework to explore the relationship between entrepreneurial competencies and financial performance.Results: The results indicate there is a positive relationship between entrepreneurial competencies and financial performance of farmers. Each of the individual competencies also indicated positive correlation between the entrepreneurial competencies and financial performance.Conclusion: An increase in specific entrepreneurial competencies behaviour may increase the operating efficiency of the farm. Educational opportunities exist to educate farmers on the potential benefits of using entrepreneurial behaviour to their advantage (to benefit their operating efficiency). Sectors involved with agriculture, for example agricultural advisors, financial advisors and educational institutes, should emphasise the importance of utilising the competencies of farmers.
