ReviewInternational aid can take on a number of forms. Traditionally, official development aid via governments and global institutions is provided by members of the Development Assistance Committee (DAC) of the Organisation for Economic Cooperation and Development (OECD). Funding through these channels is commonly referred to as DAC funding. It is, however, important to note that various other players are also active in the global aid arena, such as international foundations, non-governmental organisations (NGOs), inter-governmental organisations (INGOs) and private funders. [1,2] There is a global debate on the effectiveness of different implementation models of aid and the eventual measurement of impacts and outcomes on recipient countries and populations. There is much theorising over the intended outcomes of development and, therefore, by implication, what aid aims to achieve. The current focus in discussions around development shows a relatively holistic conception of wellbeing and quality of life, rather than narrowly defined economic measures. [3] There is furthermore an expressed need to understand the desires and intentions of all the parties involved in the aid relationship, from the political/foreign policy intentions of donors to the goals of recipients, and how these intentions and the consequent relationships were formed historically. [4] In the literature on the evolution of approaches to funding there is a trend towards criticism of traditional funding modalities and the promotion rather of more inclusive models of aid, such as South-South Cooperation (SSC), comprising collaboration between partners in the global South, and triangular models, involving development partners supporting Southern collaborations. [1,5] The latter models are thought to have advantages, [6] notably a greater focus on partnerships and co-operation.This article has four broad aims: firstly, to present the evolution of Southern approaches to development co-operation. SSC will be situated historically against the backdrop of aid generally in the post-World War II period. There is a particular theoretical background to the concept of SSC, which is importantly derived from the post-colonial experience of Africa, Latin America and Asia, loosely referred to as the developing world in current discourse. This historical positioning gives rise to a number of criticisms of traditional aid models, from terminology to practice. Secondly, it aims to indicate examples of current co-operative programmes in health and health science education in Africa, which are based on the principles of SSC and triangular aid. Some of these programmes (notably the United States President's Emergency Plan for AIDS Relief (PEPFAR)) have evolved away from strategies based on vertical interventions, and at the time of writing were active in the brokering of co-operative partnerships and the facilitation of 'twinning' relationships.[7] The latter approach is in line with those typical of SSC and triangular models.
