Understanding of how best to support those most vulnerable to climate stress is imperative given expected changes in climate variability. This paper investigates local adaptation strategies to climate variability, focusing on agricultural decision-making in a communal irrigation scheme in Vhembe District, Limpopo Province, South Africa.

Adaptation involves the management of risks posed by climate change, including variability. The identification and characterisa-tion of the manner in which human and natural systems are sensitive to climate become key inputs for targeting, formulating and evaluating adaptation policies. With the guidance presented here, users should be equipped to carry out(More)
INTRODUCTION C limate change is a key concern within South Africa. Mean annual temperatures have increased by at least 1.5 times the observed global average of 0.65 ∘ C over the past five decades and extreme rainfall events have increased in frequency. These changes are likely to continue: the 2013 South African Long Term Adaptation Scenarios and the Fifth(More)
HIV/AIDS is a key concern in South Africa. However, its impact cannot be examined in isolation of other stresses, such as food insecurity, high climate variability, market fluctuations, and poor governance. In this paper, we present an agent-based simulation model of the social impacts of HIV/AIDS in villages in the Vhembe district, Limpopo Province, South(More)
In this paper, we present an agent-based simulation model of the social impacts of HIV/AIDS in villages in the Sekhukhune district of the Limpopo province in South Africa. AIDS is a major concern in South Africa, not just in terms of disease spread but also in term of its impact on society and economic development. The impact of the disease cannot however(More)
Vulnerability to flooding is a growing concern in cities of the South, where resources are concentrated and poor people often settle in flood prone areas. Climate change projections of increased intensity and frequency of extreme rainfall events suggest flooding impacts will grow in future, demanding improved response to current flood risk in order to(More)
