“…Macadamia belongs to the Proteaceae family, subfamily Grevilleoideae, and tribe Macadamieae [71]. Eight macadamia species have been described, six of which are native to Australia and two to the Indonesian island of Sulawesi [68,71]. Macadamia tetraphylla and Macadamia integrifolia, indigenous to Australia's east coastal rainforests, produce edible kernels [72].…”

Macadamia is a high value tree crop with rising global demand. As a leading producer, Malawi has seen rapid expansion of macadamia orchards, indicating the crop’s growing economic and nutritional importance. Macadamia nuts serve as a means of income generation and provision of high-quality nutrition among producers and consumers. As a consequence of these benefits, macadamia nut production is rising within the country. Rising domestic and international demand suggests macadamia production will help in economic growth in production areas. Integrating macadamia nuts into local diets could also provide nutritional benefits, allowing Malawi to simultaneously improve well-being and prosperity. To fully utilize this potential, Malawi needs strategic expansion plans for the crop. A comprehensive assessment of current and future suitable production areas is necessary. By matching production capacity to area’s ecological conditions, yields can be optimized within sustainable limits. With mindful, coordinated support for the nascent macadamia industry, Malawi can leverage this crop for healthier, more resilient communities.

“…Nagao o C are associated with water loss that subsequently restricts the build-up of oil in the nuts and reduces their quality [37]. For precipitation, various authors have suggested a tolerable annual rainfall ranging from to 4000 mm [35][36][37][38]. Britz reported that macadamia yield in South Africa was lost due to spatiotemporal variability in precipitation and temperature [39].…”

“…Nevertheless, lower day temperatures (≤10 °C) are lethal to the crop. Nagao and Ho found that higher temperatures exceeding 30 °C are associated with water loss that subsequently restricts the build-up of oil in the nuts and reduces their quality [37]. For precipitation, various authors have suggested a tolerable annual rainfall ranging from 510 to 4000 mm [35–38].…”

Climate change is altering suitable areas of crop species worldwide, with cascading effects on people and animals reliant upon those crop species as food sources. Macadamia is one of Malawi's most important and profitable crop species. Here, we used an ensemble model approach to determine the current distribution of macadamia producing areas across Malawi in relation to climate. For future distribution of suitable areas, we used the climate outputs of 17 general circulation models (GCM's) based on two climate change scenarios (RCP 4.5 and RCP 8.5). We found that the precipitation of the driest month and isothermality were the climatic variables that strongly influenced macadamia's suitability in Malawi. These climatic requirements were fulfilled across many areas in Malawi under the current conditions. Future projections indicated that large parts of Malawi's macadamia growing regions will remain suitable for macadamia, amounting to 36,910 km2 (39.1%) and 33,511 km2 (35.5%) of land based on RCP 4.5 and RCP 8.5, respectively. Of concern, suitable areas for macadamia production are predicted to shrink by −18% (17,015 km2) and −22% (20,414 km2) based on RCP 4.5 and RCP 8.5, respectively, with much of the suitability shifting northwards. Although a net loss of area suitable for macadamia is predicted, some currently unsuitable areas will become suitable in the future. Notably, suitable areas will increase in Malawi's central and northern regions, while the southern region will lose most of its suitable areas. In conclusion, our study provides critical evidence that climate change will significantly affect the macadamia sub-sector in Malawi. Therefore area-specific adaptation strategies are required to build resilience.
