Abstract:
AbstractShade trees are important components of cocoa-agroforestry systems because they influence yields, soil fertility and the occurrence of pests and diseases and may support adaptation to climate change. Based on a review of the existing literature and on primary data from field experiments, this chapter reports on the species-specific effects of shade trees in relation to the management of insect pests, black pod diseases and their impacts on cocoa yield. Shade tree species in cocoa systems impact soil available phosphorus differently and shade tree species such as Spanish cedar (Cedrela odorata), limba (Terminalia superba) and mahogany (Khaya ivorensis) increase cocoa yield compared with cocoa systems without shade trees. The architecture of shade tree species may influence below-canopy temperatures and relative humidity, which potentially affect pests such as mirids and black pod disease infections and ultimately cocoa yield. As farmers have local knowledge of and preferences for certain shade tree species, strengthening the combination of scientific and local knowledge can prove a powerful tool for the improved management of shade tree species, as well as cocoa pests and diseases.

Abstract:
AbstractCurrent research suggests that cocoa agroforestry systems could offer stable yields, additional benefits and income from shade trees, despite potential added costs, such as from the purchase of insecticides. There is a paucity of profitability studies of different cocoa agroforestry systems. Only few of them go beyond a narrow focus on cocoa yields to model the entire agroforestry system and thus do not advance our understanding of the socio-economic value of other ecosystem goods. Based on survey data covering a thousand cocoa plots and group interviews with cocoa farmers, we explore the costs and benefits at the household level of including trees in cocoa systems. Comparing low and medium tree diversity systems, we find that income from cocoa beans, timber and fruit trees are higher and labour costs are lower in plots with medium diversity, while insecticide costs are lower on low-diversity plots. Overall, net benefits were higher on cocoa plots with higher tree diversity. Thus, cocoa agroforestry systems offer cost-reduction and income-improving advantages. Since cocoa systems vary among different agro-ecological zones in Ghana, we recommend that interventions aimed at increasing tree diversity consider the specific management practices of each farming household and the location in question.

Abstract:
AbstractAgroforestry practices in cocoa cultivation have historical roots going back to the Mayan sacred groves in Mesoamerica. Today, agroforestry cocoa, i.e., the integration of shade trees, plants and crops in cocoa systems, is promoted as a climate smart practice by public and private institutions. Shaded cocoa can sustain or even increase cocoa yields and the agroforestry systems may provide additional output for household consumption and sale as well as improve the microclimate and soil conditions on the farm. Despite these promising features, cocoa agroforestry systems are far from the norm in producing countries like Ghana. Based on discussions with groups of farmers across the Ghanaian cocoa belt, this chapter shows that while farmers are well aware of the positive aspects of shaded cocoa systems, traditional cocoa practices, village chiefs’ command of local land uses, land and tree tenure systems, alternative land uses and inability to access inputs and extension services limit the adoption and constrain the management of shade trees. As still more policies are developed to improve the Ghanaian cocoa sector, policymakers must consider these often overlooked social and institutional factors that prevent cocoa farmers from engaging in longer-term agroforestry practices and thereby benefiting from the opportunities they present.

Abstract:
AbstractClimate change is threatening cocoa production in Ghana, the world’s second largest cocoa exporter. Yet, as we have shown in this book, the impacts of climate change must be understood in the context of the multiple socioeconomic and biophysical pressures facing cocoa farmers, including the conversion of farms for other land uses, increasing hired labor costs as well as pests and diseases. This final chapter summarizes the book’s overall findings on cocoa agroforestry as climate change adaption and points to ways forward in terms of policy, practice and research. Our findings suggest that a nuanced view of farmers, agroecosystems and sites is necessary and emphasize the need to study shade tree species and species diversity, in addition to shade levels, to optimize the sustainability of cocoa farming. We further suggest that it may not be possible to sustainably grow cocoa in marginal regions of the cocoa belt, where yields are lower and where agroforestry may be unable to mitigate the negative impacts of the adverse climate. Finally, we point to the importance of considering rights and access to trees, land, extension services and resources, and call for more multidisciplinary research on differently situated farmers’ opportunities and needs.

Abstract:
AbstractClimate change is predicted to significantly reduce areas suitable for the cultivation of cocoa, an important cash crop providing a livelihood to over six million smallholders in the humid tropics. Cocoa agroforestry shows potential to increase climate resilience while providing more stable incomes, enhancing biodiversity, supporting healthy ecosystems and reducing the pace at which farms expand into forested areas. Based on the multidisciplinary ‘Climate Smart Cocoa Systems for Ghana’ research project, this book investigates the case of the biophysical and socioeconomic sustainability of cocoa agroforestry in Ghana, the second largest producer of cocoa in the world. After a brief introduction to the research project, this introductory chapter reviews the literature on the links between climate change, farming and agroforestry, thereby situating the study within a wider context. It then presents an in-depth analysis of historical Ghanaian cocoa yields and climate data at both the national and regional levels to establish a foundation for understanding the new climate risks faced by cocoa farmers. The chapter concludes by providing an overview of the chapters that follow and introducing the overall argument that agroforestry can only successfully address climate change impacts on cocoa farming if location-specific biophysical and socioeconomic factors are considered.

Full text
Abstract:
AbstractCocoa (Theobroma cacao L.) is an important cash crop in many tropical countries, particularly in West Africa. Heat and drought are both known to affect the physiology of cocoa plants through reduced rates of photosynthesis and transpiration, as well as changed physiological processes such as the functions of photosystems, chlorophyll synthesis, stomatal conductance and expression of heat-shock proteins. This in turn leads to decreased yields and increased risks of mortality under severe heat and drought. To help cocoa plants adapt to climate change, the literature suggests agroforestry as a potential farm management practice. It has been argued that the lack of tree cover in cocoa cultivation systems exposes the crop to heat and direct solar radiation, thus increasing evapotranspiration and the risk of drought. Drawing on data generated from two on-field studies, this chapter assesses the shade effect on cocoa’s physiological responses to drought and heat stress to determine whether shade would be beneficial under climate change scenarios. We conclude that shade improves the physiology of cocoa, but that this may not be sufficient to compensate for the negative effects of high temperatures and severe drought exacerbated by climate change in sub-optimal conditions.

Abstract:
Advanced midwifery practice is an autonomous status that is developed during midwifery training and practices. Advanced midwives in their practice are expected to take full responsibility when it comes to patients under their care. However, in tertiary hospitals, all the care given to maternity patients yields grey area which needs responsibility sharing between the midwives and other multidisciplinary team members like obstetric doctors and paediatric doctors. The tertiary environment is over-clouded by medical-dependent practices which is widened by the communication gap between the multidisciplinary teams. Lack of professional communication in tertiary hospitals’ work environment when it comes to sharing of accountability pushes the midwives to their cocoon shells which make them lose their patient advocacy role, knowledge, and skills. Based on the environmental expectations, set ups and practices, patients end up receiving compromised maternity care which open doors to major malpractices and complications like unnecessary loss of lives and litigations. In the presence of malpractices, there is always a tendency of the multidisciplinary team members blaming each other and mostly the blamed professionals are the midwives which strains the environmental professional relationships.

Abstract:
Indonesia is among the largest cocoa producers in the world and it makes an important contribution to the nation’s economy. In Indonesia, the cocoa pod borer (CPB) outbreaks have caused a decline in cocoa yield and quality, impacting the livelihoods of cocoa farmers. Application of Integrated Pest Management (IPM) is promoted by the Indonesian government, in collaboration with various organizations. IPM is an approach that focuses on using a combination of biological, cultural, and chemical control methods to manage pests and reduce their impact on crops. The adoption of IPM practices in cocoa farming has shown promising results in Indonesia. Farmers have reported improved yields and quality of cocoa beans, reduced pesticide use, and improved environmental sustainability. In addition, the application of IPM has equipped farmers with knowledge and skills that can help them overcome other challenges in cocoa farming, such as a healthy environment.

Abstract:
The increasing demand for sustainable waste utilization has led to growing interest in cocoa shells as a valuable biomass resource. This study investigates the pyrolysis of cocoa shells, both untreated and acid-treated, at temperatures of 300, 400, and 500°C to extract valuable compounds with potential commercial applications. Pyrolysis, a thermochemical decomposition process in the absence of oxygen, was carried out using nitrogen as the pyrolysis atmosphere to ensure optimal reaction conditions. The aim was to optimize the production of bio-oils enriched with value-added compounds, such as f

Abstract This paper is a preliminary analysis of the potential for atmospheric thermal pollution from a man-made reservoir. The specific site for the study is a proposed hydroelectric project on the Sogamoso River in Colombia, S.A. The region is agricultural with the two staple crops being coffee and cocoa. These two crops are sensitive to both high temperatures and more dramatically to high humidity levels. Farmers from the region are concerned that the construction of the reservoir will negatively impact crop yield. We have used a numerical atmospheric model to simulate weather from the regi

Abstract:
Menoreh mountainous region, especially the Samigaluh district, has been long known as a coffee producer in Yogyakarta Special Region. The coffee trees were planted with other kinds of trees, known locally as “Kebun Campur”. The advantages of “Kebun Campur” in those regions were its capability to provide food resilience and sustainability. Meanwhile, “Kebun Campur” usually has low productivity due to poor maintenance and tight competition with other plants in a small area. We introduced high-yield and aroma coffee clones from National Coffee and Cocoa Research Center (Puslitkoka), supervising t

Abstract The objective of this work is to contribute to the generation of a significant advance of the coconut agroindustry in Colombia, for which the process of spray drying was optimized to obtain coconut powder added with functionally active components (CP+PAC) (calcium and vitamins C, D3 and E), food that is framed in the context of functional foods. Initially, the behavior of the physicochemical properties of the coconut during storage at a temperature of 25ºC was evaluated. Then the base emulsion was designed, determining the influence of the composition of emulsions based on coconut mil

Abstract:
Corner-guided detector enjoys potential ability to yield precise bounding boxes. However, unreliable corner pairs, generated by heuristic grouping guidance, hinder the development of this detector. In this paper, we propose a novel corner grouping algorithm, termed as Corner Affinity, to significantly boost the reliability and robustness of corner grouping. The proposed Corner Affinity is a couple of two interactional factors, namely, 1) the structure affinity (SA), applying to generate preliminary corner pairs through the corresponding object's shallow construction information. 2) the context

Abstract:
Cocoa production has a long history in Ghana, originating in the late nineteenth century. Since then, cocoa production has seen significant changes. Originally, cocoa was cultivated in newly cleared forests in which many forest trees were preserved as shade trees. Cocoa is ideally suited to these conditions and produces high yields with minimum investment in labour and inputs. However, over time, as the forest conditions change, the cost of cultivating cocoa has increased and yields have declined. As long as new forest frontiers exist, farmers have continued to move into these areas, which hav

Abstract:
Cocoa farmers in Ghana face increasing challenges. In the past, many of them could make a living from cocoa thanks to the advantages – ‘forest rents’ – that initially apply when forest is cleared to create cocoa farms: fertile soils, few pests and diseases. With time, however, weeds invade, pests and diseases build up, and trees age. To maintain production requires more labour, more inputs and more skill. In the past, farmers would often abandon older groves and seek new forest to clear. As they did so, the frontier for cocoa farming moved westwards across Ghana to the remaining high forest. B

Abstract:
The production of a renewable energy from biomass, such as ethanol by fermentation, has received special attention as a consequence of the world energy crisis. Nowadays, gasohol E-10, a mixture of 10% ethanol and 90% gasoline has been widely used in vehicles in Thailand and there is an attempt to promote the use of E-20 or E-85 in the vehicles in the near future. Ethanol fermentation by conventional batch suffers from various constrains such as, low cell density and rather time consuming. Although continuous fermentation by suspended cell culture can be used to speed up the process, it is more
