Background: The in-depth traditional knowledge of medicinal plants is at risk of extinction due to the dependency on oral transmission, and as such, there is an urgent need to document such knowledge. This study aimed to document indigenous uses of medicinal plants among community members in the Ejisu-Juaben Municipality. Methods: Data was collected in 2016 from community members and local herbalists in the Ejisu-Juaben Municipality through a semi-structured questionnaire. Statistical tools and ethnobotanical indices, i.e., informant consensus factor (ICF), fidelity level (FL), and use value (UV) were used to analyse the data. Results: One hundred and six medicinal plants belonging to 45 families were reported to cure 68 different human diseases. The most frequently used plant part in this study was the leaves (52%). Decoction (57.5%) and oral administration (58.3%) were the most utilised herbal preparation and administration route respectively. Cleistopholis patens had the highest UV (0.54) with pain & fevers and skin diseases having the highest ICF values (0.88 and 0.85 respectively). Furthermore, new medicinal uses of Hilleria latifolia and ten other species were recorded for the treatment of the traditional local disease, aseram. Conclusions: The current knowledge and uses of medicinal plants are still high in the study area based on the high degree of consensus among informants. This study could allow for the preservation of knowledge and biodiversity of medicinal plants, both of which are threatened with extinction.

This book chapter addresses the urgent need to shift from traditional practices to sustainable intensification, particularly in regions where environmental constraints and the impacts of climate change are pronounced. It provides an in-depth overview of sustainable intensification, focusing on its core principles to increase food production from existing farmland while minimizing environmental harm. Key aspects discussed include agroecosystem management, where the complex interactions between plants, soil, and microorganisms are explored, along with the critical role of soil biodiversity in maintaining ecosystem productivity. The chapter also emphasizes the importance of proper nutrient management, analyzing the effects of nutrient deficiency on plant health and productivity. It advocates for integrated nutrient management to optimize soil health and crop yields. Innovative practices such as breeding for nutrient use efficiency, crop rotation, intercropping, and advanced technologies like precision agriculture are also highlighted as vital strategies for sustainable intensification. Moreover, the chapter underscores the necessity of supportive policy frameworks and community engagement in promoting sustainable agricultural practices. The importance of sustainable intensification in ensuring food security and economic stability has been thoroughly discussed, offering practical recommendations for stakeholders to foster resilient and sustainable agroecosystems in the face of climate change.

Faced with global challenges such as population growth, resource scarcity, and climate change, the world must find sustainable agricultural solutions. Precision agriculture (PA) and the circular economy (CE) emerge as viable options. Our paper explores how these frameworks, along with their associated strategies and examples from Ghana, can address issues such as soil degradation, low productivity, limited diversification, postharvest losses, and heightened climate vulnerability among small farms. By incorporating PA strategies such as organic farming, legume‐crop integration, drone technology, water‐smart farming, aquaponics fish production, hydroponics, innovative mushroom and snail farming, deployment of smart crop varieties, bundling, and agroecology CE principles that maximize productivity per unit area, practitioners can bolster climate resilience, enhance food security, and support rural livelihoods. Adopting strategies such as vertical farming for vegetable production, integrated aquaponics‐based food systems, mushroom production, and improved crop varieties will pave the way for a sustainable future in agriculture. The current study deployed a systematic review to examine the trends, implications, and contributions of PA and the CE to food security and agricultural production in Ghana over the past decade. The findings revealed the various PA and CE strategies adopted in Ghana, along with their potential benefits and synergies.
