    The water footprint of biodiesel produced from sunflower in South Africa
    (MDPI, 2022) Netshifhefhe, Khwathiso; Jordaan, Henry
    The use of feedstock crops for the production of biodiesel suggests that biodiesel production may have a major impact on the scarce freshwater resource in South Africa. This paper aimed to assess the green plus blue water footprints (WFgreen+blue) of biodiesel produced from sunflower in South Africa using the Global Water Footprint Standard approach. The green (WFgreen) and blue water footprint (WFblue) at the farm level were assessed for sunflower grown under the rain-fed and irrigation production system respectively. The results show that 2617 m3 and 2477 m3 are required to produce 1 ton of rain-fed and irrigated sunflower respectively. At the processing level, about 7.12 L of blue water is required to produce 1 L of biodiesel from sunflower. The WFblue at the processing stage of biodiesel produced from irrigated sunflower was 1.01 m3/GJ, compared to 1.15 m3 m3/GJ from rain-fed sunflower. The WFgreen+blue of biodiesel produced from irrigated and rainfed sunflower was 2477 and 2617 m3/ton, respectively. WFgreen was the largest, accounting for about 59% and 99% for biodiesel produced from irrigated and rain-fed sunflower, respectively. It was further found that water consumption at the farm level accounted for about 99% of the WFgreen+blue of biodiesel in both production systems. Management practices that improve water use efficiency at the farm level may help to lower the WFgreen+blue of biodiesel. Interestingly, the WFgreen+blue is lower for biodiesel produced from irrigated sunflower than for rainfed sunflower. The blue water scarcity assessment showed that blue water scarcity is low during the period when sunflower requires water. As such, purely from a water use perspective, irrigated sunflower production in the Orange Riet Irrigation Scheme may be considered sustainable.

    Youth participation in agriculture, accounting for entrepreneurial dimensions
    (AOSIS, 2022) Henning, Johannes I. F.; Jammer, Brent D.; Jordaan, Henry
    Background: Despite the high youth unemployment levels, especially in sub-Saharan Africa, participation in the agricultural sector remains low. The agricultural sector provides valuable opportunities of employment, which could contribute towards relieving the high levels of unemployment and enhancing livelihoods of families in rural areas. Youth are also seen as the future of the agricultural sector and food production. Aim: To determine whether entrepreneurial dimensions, along with assets within the sustainable livelihoods framework, influences participation of youth in the agricultural sector. Setting: Focus is on youth and the influence of endogenous and exogenous factors on their participation in the agricultural sector. Methods: Entrepreneurial dimensions of 440 youth participants were derived from statements related to entrepreneurial skills and competencies by means of principal component analysis and combined with factors from the sustainable livelihood framework in a multinomial logistic regression. Results: It was found that the youth are heterogeneous in their endogenous and exogenous resources. Youth involved in the sector are more likely to have access to land and extension services, experience in the sector and support initiatives. In terms of entrepreneurial dimensions, youth involved are more inclined to believe in themselves and are more likely to take advantage of opportunities (pull entrepreneurship). The results show that policies and programmes should consider both endogenous and exogenous factors and combinations thereof to attract and enhance youth participation in the agricultural sector. Conclusion: Policy and programme development should consider the heterogeneity of youth in terms of their access to resources and entrepreneurial dimensions to enhance their participation in the agricultural sector. Participation in agriculture requires more than only access to land, and other individual physical resources attention should also be given to endogenous factors of individuals and combinations of different resources.
