“…This is consistent with the literature that shows that these practices can improve both productivity and profitability (D'Annolfo et al, 2017). The findings are also consistent with other pieces of literature (Brzozowski and Mazourek, 2018; Wei 2020) that opined that agroecological innovation can have a significant contribution to sustainably boosting the yield of crops.…”

Despite the potential of agroecological practices to promote sustainable agrifood systems, their adoption among farmers is limited, and there is insufficient information regarding their impact on farm performance. This study evaluates the adoption of agroecological practices and their impact on farm performance among vegetable farmers in Botswana. The multivariate probit model was used to understand the complementarity and/or substitutability of the key agroecological practices under consideration—mulching, cover cropping, afforestation, and minimum tillage, as well as their determinants. Furthermore, the direct two-stage least squares (direct-2sls) technique within the framework of instrumental variable treatment effect regression (ivtreatreg) was used to eliminate self-selection bias that may be evident as a result of observed and unobserved characteristics. The results indicated that the agroecological practices are complementary and that the practice of one agroecology is conditional on another. The factors shaping the adoption of these agroecological practices vary among them. Furthermore, the adoption of agroecological practices led to a significant improvement in farmers' net revenue and yield, and farmers that did not adopt any of the practices would have been better off if they had adopted them. These findings have significant implications for stakeholders and will boost the campaign for the adoption of agroecological practices to improve farm performance and, consequently, farmers' welfare.

“…Access to information can thus become the key element in combating the excessive use of chemical fertilizers in agriculture. According to Wei (2020), access to information allows farmers to reduce production costs and be more economically viable and socially acceptable. The use of advanced agricultural technologies in the practice of agroecology is not optional; it is necessary to ensure sustainable agriculture.…”

In the ever-evolving landscape of science and technology, the fields of engineering and environmental sciences have emerged as the vanguards of innovation and sustainability. These domains intersect and intertwine, shaping the future of our world. This book is a testament to the pursuit of knowledge and progress in these crucial areas. A diverse array of topics is proposed that not only reflect the current state of these disciplines but also illuminate the path ahead. Our aim is to provide a comprehensive overview of the developments in engineering and environmental sciences, offering a valuable resource for scholars, researchers, and practitioners. The chapters contained within this book span a wide spectrum of subjects, each contributing a unique facet to the ever-expanding mosaic of knowledge. The opening chapters delve into the world of advanced materials and innovative engineering practices. Self-healing composites, with their transformative ability to repair structural damage autonomously, promise to revolutionize industries ranging from aerospace to construction. Lattice structures and FDM printed parts explore the intricate balance between design and function, pushing the boundaries of what is possible in manufacturing and construction. The next contributions traverse the frontier of biotechnology and its applications. Nanobiotechnology takes us into the realm of the infinitesimally small, where nanomaterials and techniques hold immense potential for fields such as medicine, energy, and environmental remediation. Biomaterials open doors to the development of biocompatible materials, spurring advancements in healthcare and regenerative medicine. Microbial safety underscores the importance of understanding and managing microorganisms in various environmental contexts. Other chapters explore the broader systems and environmental aspects of engineering. Server queueing models provide insights into optimizing digital infrastructures, crucial in an increasingly interconnected world. Climate-smart agriculture offers solutions to feed a growing global population while mitigating the impacts of climate change. Deep learning architectures, inspired by the human brain, unlock new horizons in artificial intelligence and data analysis. Thank you for joining us on this exciting expedition into the fields of engineering, science, and the environment. The voyage ahead is filled with challenges, but it is also packed with limitless possibilities and discoveries waiting to be made. Sincerely,Prof. Raul D.S.G. CAMPILHO

“…Experts have been puzzled about Africa’s growing inability to feed itself despite possessing most of the world’s uncultivated farmland for a significant period of time [ 76 ]. The majority of SSA’s net agricultural import bill comes from four countries: Nigeria, Angola, the DRC, and Somalia [ 77 ]. Most of the food that is imported may be grown domestically, according to a report by [ 78 ].…”

All around the world, inequalities persist in the complex web of social, economic, and ecological factors that mediate food security outcomes at different human and institutional scales. There have been rapid and continuous improvements in agricultural productivity and better food security in many regions of the world during the past 50 years due to an expansion in crop area, irrigation, and supportive policy and institutional initiatives. However, in Sub-Saharan Africa, the situation is inverted. Statistics show that food insecurity has risen since 2015 in Sub-Saharan African countries, and the situation has worsened owing to the Ukraine conflict and the ongoing implications of the COVID-19 threat. This review looks into multidimensional challenges to achieving the SDG2 goal of “End hunger, achieve food security and improved nutrition, and promote sustainable agriculture” in Sub-Saharan Africa and the prosper policy recommendations for action. Findings indicate that weak economic growth, gender inequality, high inflation, low crop productivity, low investment in irrigated agriculture and research, climate change, high population growth, poor policy frameworks, weak infrastructural development, and corruption are the major hurdles in the sustaining food security in Sub-Saharan Africa. Promoting investments in agricultural infrastructure and extension services together with implementing policies targeted at enhancing the households’ purchasing power, especially those in rural regions, appear to be essential drivers for improving both food availability and food access.
