Medicinal plants research in Asia continues to receive significant national and international attention, particularly concerning its multiple roles in poverty alleviation and health care support. However, scientific information on the institutional arrangements, the potentials of different medicinal plants production systems, and the utilization methods, remain highly fragmented. This incomprehensive information base shades the development of a comprehensive research agenda to improve the current body of knowledge, at least in the context of Asia. To address this impasse and propose future research perspectives, we systematically reviewed 247 journal articles, 15 institutional reports, and 28 book chapters. From the reviews, five key lessons are drawn: (i) Asian medicinal plant production systems demonstrate some dynamics, characterized by a gradual but continuous shift from wild gathering to cultivation, (ii) sub-regional variations exist with regards to the appreciation of medicinal plants potentials for traditional healing, modern healthcare, and livelihoods support, (iii) knowledge on the effect of multi-scale institutional arrangements (formal and informal) on medicinal plant management practices is fragmented, (iv) very few studies dwell on the challenges of medicinal plants commercialization, particularly with regards to the role of middlemen, boom–bust cycle, raw material readiness, and product quality, and (v) law enforcement, benefit and knowledge sharing, and research and development should be prioritized to serve the interest of medicinal plants production actors. To further extend the body of knowledge on medicinal plants in Asia, we advance the need for empirical investigations on the performance of medicinal plants production systems and their contribution to livelihoods in diverse institutional contexts.

Anticipating seasonal and shorter time scale dynamics to farming practices is primordial for indigenous farmers’ resilience under extreme environmental conditions, where climate change is a menace to agro-hydro-ecological systems. This paper assesses the effectiveness of indigenous farmers’ knowledge and aptitude to read weather signs for informed decisions on their daily and seasonal activities. Such climate-proof development is anchored on indigenous people’s knowledge and perceptions in circumstances where the dearth of scientific evidence or information exists as in Cameroon. The study is based on eight focus group discussions and a survey of 597 farming households in seven agro-ecological basins on the Bui Plateau of the Bamenda Highlands. The results indicate that indigenous smallholder farmers value their ability to accurately observe and anticipate local conditions in various ways to serve their local realities more aptly than outside forecasts. Such local knowledge should thus exercise a complementary role weave in a local climate information understanding system that replicates ecological variability.

The assessment of research performance is widely seen as a vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress. Academic institutions need to take critical decisions on hiring and promotion, while facing external pressure by also being subject to research assessment^1–4. Here we present an outlook on research assessment for career progression with specific focus on promotion to full professorship, based on 314 policies from 190 academic institutions and 218 policies from 58 government agencies, covering 32 countries in the Global North and 89 countries in the Global South. We investigated how frequently various promotion criteria are mentioned and carried out a statistical analysis to infer commonalities and differences across policies. Although quantitative methods of assessment remain popular, in agreement with what is found in more geographically restricted studies^5–9, they are not omnipresent. We find differences between the Global North and the Global South as well as between institutional and national policies, but less so between disciplines. A preference for bibliometric indicators is more marked in upper-middle-income countries. Although we see some variation, many promotion policies are based on the assumption of specific career paths that become normative rather than embracing diversity. In turn, this restricts opportunities for researchers. These results challenge current practice and have strategic implications for researchers, research managers and national governments.

Surging extreme events, particularly floods, have stimulated growing research on their epidemiology, management, and effects on livelihoods in Sub-Saharan Africa (SSA), especially for agriculture-dependent households. Unfortunately, the topical literature is still characterized by independent, isolated cases, with limited relevance to understanding common flood effects across geographical space and time. We bridge this knowledge gap by analyzing the effects of multiple cases of flash, coastal and riverine-cum-pluvial (‘complex’) floods on agriculture-dependent livelihoods in three (Sudano Sahelian, Coastal and Western Highlands) geo-ecological zones in Cameroon. The analysis makes use of a sample of 2134 flood victims (1000 of them in the Sudano-Sahelian, 242 in the Coastal, and 892 in the Western Highlands zones) of 26 independent community floods: 11 in the Sudano-Sahelian, 3 in the Coastal, and 12 in the Western Highlands zone. Irrespective of flood type and geo-ecology, agriculture-dependent livelihoods were gravely impaired. However, the impacts on livelihoods and public goods (such as road or communication systems) significantly varied in the different geo-ecological zones. The study concludes with the need to include context-specificity in the flood impact assessment equation, while identifying common effects, as is the case with agriculture in this study. We emphasize the need to up-scale and comparatively analyze flood effects across space and time to better inform flood management policies across SSA.

This paper examines the determinants and policy implications of active and healthy ageing in Sub-Saharan Africa, taking the case of Bamenda, in Cameroon. Specifically, the study sought to identify and explore the determinants of active and healthy ageing using a mixed-methods approach involving qualitative and quantitative data collection and analysis. Focus group discussions were conducted complemented by a survey (random and snowball sampling) using a structured questionnaire. Narratives and thematic analysis were used to analyze the data generated from the focus group discussion and Tobit regression was employed to analyze the multiple determinants of active ageing by dimensions and on a global scale in Cameroon. Results identified three key dimensions of active and healthy ageing: employment/livelihood options (EL), community support and health (CH) and housing and living in Bamenda (HL). The regression results reveal gender bias in active ageing, a non-effect of education and health on active ageing, and a positive effect of income on active and healthy ageing. This study contributes, among others, to the competence–environmental press theory on active ageing with regards to unbundling context specific determinants of active and healthy ageing. It equally derives policy considerations with regards to gender mainstreaming and the identification of age friendly income earning options to enhance the active and healthy ageing process.
