“…On the other hand, in the country, the demand for cultivation of better quality coffee is increasing from time to time. To satisfy the ever increasing demand of coffee cultivars, several improved Arabica coffee varieties that are characterized by better cup quality, yield, and tolerance to coffee diseases than the traditional ones have been released for cultivars since the early 1970s [17][18][19]. To complement the existing study, in this work, the influence of growing altitudes on concentrations of caffeine, 5-CQA, and nicotinic acid of four Coffee arabica le varieties grown in southwest of Ethiopia has been studied.…”

The influence of altitude on caffeine, 5-caffeoylquinic acid (5-CQA), and nicotinic acid contents of Arabica coffee varieties grown in Southwest Ethiopia was investigated. High-performance liquid chromatography with diode array detector (HPLC-DAD) was used for the determination of the target analytes. Coffee samples were collected from four coffee varieties, named as 74112, 7454, 7440, and 74110, which are cultivated in high, mid, and low altitudes in the study area. The findings of the study showed that the contents of caffeine and 5-CQA in both raw and roasted coffee beans decrease as the growing altitude increases and, thus, for all varieties, their highest concentrations were recorded in lowland coffee beans. Nevertheless, the contents of nicotinic acid increase as the altitude rises and, thus, the highest nicotinic acid content was recorded in highland coffee samples. Besides, after roasting, the contents of caffeine were increased, whereas the contents of 5-CQA were lowered, indicating the possibility of its degradation during the roasting process. Both green and roasted coffee beans also contained relatively higher concentrations of nicotinic acids. Other than the growing altitudes, the contents of caffeine, 5-CQA, and nicotinic acid in coffee beans also vary with coffee varieties. Therefore, coffee varieties that are cultivated at various altitudes may have different biochemical compositions such as caffeine, CGAs, and nicotinic acid that could greatly influence the flavor, aroma, and stimulating attributes of coffee cup quality as well as dietary benefits.

“…Coffee berries develop during the rainy season and are harvested at the beginning of the dry season. In this region, the income of 77% of smallholder farmers depends on coffee production, and the impact of climate change on coffee production will thus affect millions of lives (Diro et al 2019 ).…”

Increasing temperatures and shifting precipitation patterns have major consequences for smallholder farmers, especially in the Global South. Our study examined spatial patterns and climatic drivers of farmers' perceptions of climate change, and how these perceptions translated into adaptation actions. We interviewed 56 farmers in southwestern Ethiopia and analyzed ERA5-Land reanalysis climate data from 1971 to 2020. The majority of farmers perceived the recorded temperature increase as well as a decrease and shift in the timing of rainfall. Perceived climate change varied with local climate factors and not with the rate of climate change itself. Farmers' adaptation practices showed associations with local temperature, but not with farmers’ perceptions of climate change. Our findings highlight that even if farmers perceive climate change, perceptions are most common in areas where climate action is already urgent, and perceptions may not translate into adaptation. Thus, targeted and timely information and extension programs are crucial.

“…Food insecurity is a serious challenge in Malawi, as most agricultural production falls short of its potential due to climate change, soil fertility, and management practices [56]. Maize is a critical aspect of food security among Malawians, with access to and sufficient output of this staple being vital determinants [57].…”

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.
