The year 2023 marks the diamond jubilee of the establishment of the Organisation of African Unity (OAU), currently known as the African Union (AU), which was founded in Addis Ababa. The visionary founders, including President Kwame Nkrumah and Emperor Haile Selassie, aimed to bring about political change in African states and restore the dignity of African people, who had long suffered under colonial subjugation and disenfranchisement. Their vision encompassed a united Africa, free from oppression, governed by self-determination, and destined for prosperity.

Over time, the OAU transformed into the AU, with the intention of accelerating the dream of African unity and eradicating the social, political, and economic challenges that had begun to define African states. Pan-Africanism emerged as a beacon of hope, inspiring many who understood its significance at the organisation's inception. As we reflect on the ideals cherished by the founding fathers and reaffirmed by their successors in 2002, it is crucial to contemplate four of the seventeen aims articulated during the launch of the African Union in Durban.

Unity and solidarity between African countries and their people

Firstly, the AU aims to achieve greater unity and solidarity between African countries and their people. In pursuit of this goal, notable actions have been taken, such as the establishment of the Peace and Security Council (PSC) to maintain peace in conflict zones such as Mali, Sudan, Somalia, and the Central African Republic. Moreover, in response to the COVID-19 pandemic, the AU set up the Africa Medical Supplies Platform (AMSP) to facilitate the procurement and distribution of medical equipment and supplies throughout the continent. While these achievements are commendable, the majority of the other intentions under this aim lack a concrete plan of action, and the lack of sufficient funding is hampering progress. This presents a cause for concern.

Secondly, the AU pledged to defend the sovereignty, territorial integrity, and independence of its member states. Despite the development of intervention instruments to support this aim, the organisation has been found wanting at critical junctures. One cannot forget the adoption of Resolution 1973 by the United Nations Security Council, which authorised national governments or regional organisations to impose a no-fly zone in Libya, ultimately leading to the assassination of Colonel Muammar Gaddafi. Colonel Gadhafi played a pivotal role in the formation of the African Union and declared his vision for the United States of Africa with a single government and one currency. Surprisingly, three AU member states – South Africa, Nigeria, and Gabon – voted in favour of this resolution. Their actions raised doubts about their commitment to defending the sovereignty, territorial integrity, and independence of the AU.

Africa faces a harsh reality

Africa, a continent with immense potential for growth and development, faces a harsh reality that cannot be ignored. Its burgeoning population holds great promise for contributing significantly to its advancement. Additionally, Africa is blessed with abundant mineral resources, the prudent management of which could sustain the developmental aspirations of its people. Furthermore, Africa's expansive land mass and diverse climate present valuable opportunities to address crucial concerns such as food and energy security. It is perplexing that Africa, a continent three times the size of the United States of America, continues to lag behind in all aspects of development. The continent has enormous potential to foster growth and development and to compete on a global scale. Regrettably, it has thus far failed to harness this potential, leaving the dream of African prosperity, initially envisioned by the founders of the OAU (AU) and their successors, frustratingly out of reach.

As we commemorate the diamond jubilee of the OAU's establishment, let it serve as a reminder of the vision and determination of its founders. Their dreams for an Africa united, free from oppression, and governed by self-determination still resonate today. It is our collective responsibility to ensure that these dreams are no longer scuppered, but rather transformed into a vibrant reality of African prosperity.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
