Abstract:
Understanding the coexisting effects of population aging and a rising burden of diabetes for healthy longevity is of key importance in South Africa. We used longitudinal data from the 2015 and 2018 waves of the “Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa” (HAALSI) study to explore life expectancy (LE) and disability-free life expectancy (DFLE) of adults aged 45 and older with and without diabetes in rural South Africa. We estimated LE and DFLE by diabetes status using Markov-based microsimulation. We find a clear gradient in remaining LE and DFLE based on diabetes status. At age 45, a man without diabetes could expect to live an additional 26.8 [95% CI: 25.22 – 28.44] years, compared with 19.4 [95% CI: 15.59 – 22.79] years for a man with diabetes. For women, these figures were 33.7 [95% CI: 32.44 – 35.08] years for those without diabetes and 29.8 [26.26 – 33.17] years for those with diabetes. Individuals with diabetes lived proportionately more years subject to disability than individuals without diabetes. Additional analyses using marginal structural models to control for sociodemographic and health differences between diabetic and non-diabetic populations suggests that these factors only minimally explain LE and DFLE differences between these groups. Our findings highlight the large and important shortfall in healthy aging for people with diabetes in South Africa. This finding should motivate efforts to strengthen prevention and treatment efforts for diabetes and its complications for older adults in this setting.

Georgia Troup’s 2021 thesis is entitled
Understanding the influence of nutritional drivers on the habitat use of African elephants (Loxodonta africana) living in a semi-arid, anthropogenic landscape.

She concludes that her ‘Results also highlight the success of Rukinga in providing a safe refuge for elephants when travelling outside the national parks and into areas of human disturbance. Ultimately, the findings of this thesis highlight how the habitat use of elephants in Tsavo is influenced by nutritional drivers, specifically protein.’

‘Transforming irrigation in southern Africa’ , a project at the Fenner School, is described at https://fennerschool.anu.edu.au/research/projects/transforming-irrigation-southern-africa

The Fenner School has advised that it has ‘received funding for an extension to June 2023, the aim of which is:
By June 2023, we propose to evaluate the extent to which gains comprising increased production, reduced irrigation, increased resilience, and reduced emissions are “climate smart ”, in the face of high climate variability, by evaluating and quantifying the climate change adaptation benefits from irrigation improvements (institutional, technical and non-technical) promoted by the Transforming Irrigation in Southern Africa (TISA) project.

We will receive $600,000 from the Australian Government from ACIAR / DFAT, our focal countries in SSA remain the same i.e. Tanzania, Mozambique and Zimbabwe. ‘
