Chapter 8 provides a comprehensive review of literature pertaining to agroecological (AE) farming approaches/practices and knowledge driven from stakeholders’ and scientific studies. The review identifies the major drivers, barriers, gaps, and opportunities of AE practices in the context of African farming systems. The chapter presents the best combinations of AE practices as alternative approaches to the current unsustainable farming practices. Experiences from Zambia and other countries where selected AE practices are being implemented by farmers with the support of diverse stakeholders are shared in the chapter. Further, key ecological, social, and economic indicators developed in the countries are also discussed. The chapter analyses how the AE practices contribute to the reduction of GHG emissions and at the same time address the UN Sustainable Development Goals (SDGs), e.g., SDG 2 (food and nutrition security), SDG 12 (sustainable food production and consumption), SDG 13 (climate action), and SDG 15 (life on land).

Chapter 6 provides a summary of research findings from the case studies in India that showed significant benefits of another climate-smart rice system, namely the direct seeded rice (DSR), which shows positive outcomes compared to puddled transplanted rice in terms of (i) higher water productivity, (ii) reduction in labour and production costs, and (iii) lower methane emissions. However, there are some challenges for adopting DSR which include poor weed control, need for specific water and nutrient management, availability of suitable varieties for DSR, increased damage by soil pathogens and nutrient disorders, especially N and micronutrients. Possible solutions to overcome these challenges that will make it easier for adoption by farmers will be analysed in this chapter. Field data/evidence from India and other previous studies under both dry and wet conditions were presented to support the solutions. The options for scaling up DSR combined by need-based farmer trainings, accessibility to good quality seeds, availability and use of drum seeders and selective herbicides were discussed.

In Chapter 2, the authors focus on the importance of precision-based soil and nutrient management practices tested on rice farms in the eastern part of India and the potential for reducing GHG emissions. This is highly relevant for countries such as India, Vietnam, Myanmar, Bangladesh, and Thailand with large areas under rice production, where the use of excess amounts of fertilizer and chemicals, especially nitrogen fertilizer, is a serious problem for the environment and health of people. The chapter shows the importance and benefits from the use of tools ranging from the simple leaf colour chart to innovative digital tools and their relevance to improve nutrient use efficiency. The chapter towards the end provides guidelines/models and policy recommendations for upscaling precision soil and nutrient management in rice systems and other related food crops.

The final chapter in the book summarizes the key messages and recommendations from the disparate chapters. The chapter provides the challenges and at the same time an optimistic note about future climate actions citing some of the ongoing good initiatives. The possible technical, investment and policy options necessary for upscaling CNRFS are highlighted toward the end.

This book presents evidence-based research on climate-neutral and resilient farming systems and further provides innovative and practical solutions for reducing greenhouse gas emissions and mitigating the impact of climate change.Intensive farming systems are a significant source of greenhouse gas emissions, thereby contributing to global warming and the acceleration of climate change. As paddy rice farming is one of the largest contributors, and environmentally damaging farming systems, it will be a particular focus of this book. The mitigation of greenhouse gas emissions needs to be urgently addressed to achieve the 2°C target adopted by COP21 and the 2015 Paris Agreement, but this is not possible if local and national level innovations are not accompanied by international level cooperation, mutual learning and sharing of knowledge and technologies. This book, therefore, brings together international collaborative research experiences on climate-neutral and resilient farming systems compiled by leading scientists and experts from Europe, Asia and Africa. The chapters present evidence-based research and innovative solutions that can be applied or upscaled in different farming systems and regions across the world. Chapters also present models and technologies that can be used for practical implementation at the systemic level and advance the state of the art knowledge on carbon-neutral farming. Combining theory and practice, this interdisciplinary book provides guidance which can inform and increase cooperation between researchers from various countries on climate-neutral and resilient farming systems. Most importantly, the volume provides recommendations which can be put into practice by those working in the agricultural industry, especially in developing countries, where they are attempting to promote climate-neutral and resilient farming systems. The book will be of great interest to students and academics of sustainable agriculture, food security, climate mitigation and sustainable development, in addition to policymakers and practitioners working in these areas.

There is increasing empirical support for the biodiversity and ecosystem service (ES) benefits of mixed-species production forests. However, few studies control for the spatial arrangement of the trees within mixtures to determine the influence that clustering the tree species (patch scale mixtures), versus evenly dispersing them (intimate scale mixtures), may have for biodiversity and ES outcomes. To highlight the potential implications of altering tree spatial arrangement in mixtures, and the need to fill related knowledge gaps, here we provide a qualitative multi-disciplinary overview of ecological and socio-economic drivers with the potential to alter biodiversity, ecosystem services, and management-related outcomes from patch versus intimate scale mixtures. We focused our overview on even-aged mixtures of Norway spruce (Picea abies) and birch (Betula pendula or B. pubescens) in Sweden, which enabled us to contrast findings within a biogeographical and silvicultural setting. Specifically, we targeted implications for biodiversity (understory vascular plants, epiphytic lichens, saproxylic beetles, birds), biomass production, harvesting costs, management ease, recreation and aesthetics, cervid game, as well as abiotic and biotic risks (wind, fire, pathogens, pests, browsing damage). In the absence of direct empirical evidence, we primarily relied on expert inference from theory and relevant empirical studies sourced from the Fennoscandian region, and further afield if needed. Collectively these efforts allowed us to develop a number of informed hypotheses indicating that for spruce-birch mixtures in this region, patch scale mixtures may have the potential to favour the diversity of several forest dependant taxonomic groups, cervid game and reduce harvesting costs, whereas intimate mixtures may have the potential to reduce pathogen and pest damage, and likewise, potentially benefit production outcomes. Current knowledge was too limited, inconsistent or context dependant to even tentatively infer outcomes for fire risk, wind damage, browsing damage, management ease, recreational and aesthetic outcomes. We emphasize that our hypotheses require testing, but are sufficient to (1) highlight the likely importance of spatial-scale to biodiversity and ecosystem services outcomes in mixed-species production forests, (2) caution against generalization from mixture studies that lack scale considerations, and (3) motivate the targeted consideration of spatial grain in future mixture studies.
