Charcoal Food And Water Production In The Tropics Applying Nexus Thinking To Improve Research And Policy Approaches In Complex Landscapes

Editorial: Tuyeni H Mwampamba, Rob Bailis, Adrian Ghilardi Urbanization, food, and water consumption trends in many tropical countries show that demand for charcoal (as a source of cooking energy), meat, grain and water will rise to proportions that surpass the ability of existing ecosystems to supply these services simultaneously and at desired qualities. Consequently, drastic changes to policy and practice are needed to improve ecosystem potential and/or alter demand trends. Traditional charcoal production in sub-Saharan Africa, South East Asia and Latin America often competes or co-exists with livestock keeping and agriculture and has a tendency to occur in water-limited woodlands. The co-occurrence of charcoal and food production results in complex landscapes characterized by strong interactions between subsystems, managed by multiple sets of actors, with potentially competing objectives. These social-ecological systems provide goods and services that are essential to millions of people throughout the global south. Nevertheless, there have been very few detailed studies of such systems, particularly on the individual and combined effects of charcoal, crop, and livestock production on the hydrological system that maintains them and vice versa. As a result, these multi-use landscapes are typically managed by short-sighted, highly generalized, mono-sectorial policies that ignore important tradeoffs and undercapitalize on synergies. A system-level approach could provide important insights that improve and expand current understanding of this energy-food-water nexus. Tackling urgent and complex problems composed of multiple and interrelated factors lies at the heart of nexus thinking - an approach that “examines the inter-relatedness and interdependencies of environmental resources and their transitions and fluxes across spatial scales and between compartments” (UNU-FLORES 2015) and relies on interdisciplinary research and multi-sector policy teams. It has attracted significant interest from international organizations, the private sector and governments as a way to develop integrated equitable solutions that involve inputs from multiple stakeholders. However, this approach is notably absent in the research arena. Identifying appropriate interventions for achieving sustainable charcoal and food production and maintaining the underlying hydrological system on which they depend requires that the systems are considered simultaneously and that their biophysical, social, and political inter-relations are well understood. Taking charcoal as the nexus entry-point, this Research Topic aims to generate new understanding of charcoal production systems by incorporating agriculture and hydrology into the matrix. We were interested in empirical articles, reviews, meta-analytical articles and perspective papers that address at least two of the three nexus components and which offer provocative and insightful perspectives into the nexus as a whole. We hope that this Research Topic will 1) facilitate identification of research gaps, policy opportunities and priorities for the nexus, 2) kick-start the development of a community of researchers and practitioners working on the nexus, and 3) permit the development of a research agenda that explores the nexus globally across multiple study sites.

The book’s primary intention is to serve as a roadmap for professionals working in developing countries interested in the Nexus Water-Energy-Food-Ecosystems (WEFE) approach. The book shows a multi-disciplinary approach, showcasing the importance of the proper use of Nexus WEFE when implementing certain development programs in regions around the globe. It can be presented as a manual for an individual that either wishes to implement intervention projects following the NEXUS approach or students interested in cooperation and development. The book begins with a general explanation of the theoretical concepts and implementation processes of Nexus WEFE and continues getting into case studies, explaining the importance of proper implementation and potential drawbacks and solutions to them. This book has a particular focus on the European Union cooperation policies when implementing such an approach in developing countries.

Charcoal is widely used for cooking and heating in developing countries. The consumption of charcoal has been at high level and the demand may keep growing over the next decades, particularly in sub-Saharan Africa. Some preliminary studies indicate that among commonly used cooking fuels, unsustainably produced charcoal can be the most greenhouse gas intensive fuels and simple measures could deliver high GHG mitigation benefits. Through the Paris Agreement on climate change adopted in 2015, countries set themselves ambitious targets to curb climate change, and forest-related measures have an important role to play in climate change mitigation and adaptation. Over 70% of the countries who have submitted their (intended) nationally determined contributions (NDCs) mention forestry and land use mitigation measures. Despite the importance of woodfuel in many countries, few have explicitly included measures to reduce emissions from woodfuel production and consumption. Many of the NDCs that include forestry do not yet provide detailed information on how mitigation is to be achieved. The overall objective of the publication is to provide data and information to allow for informed decision-making on the contribution sustainable charcoal production and consumption can make to climate change mitigation. More specifically, the publication aims to answer the following questions: - What are the climate change impacts of the current practices on charcoal production and consumption worldwide and across regions? - What is the potential of sustainable charcoal production in GHG emission reductions and how such potential can be achieved? - What are the key barriers to sustainable charcoal production and what actions are required to develop a climate-smart charcoal sector?

The report creates contexts for a systemic understanding of the CGIAR Transforming agric-food system (TAFS-WCA) initiative starting with work package (WP) 3 and expanding the causality effects across the other WPs of the Initiative. The main focus of WP3 is inclusive landscape management, whereby access to and proper use of land and water resources is a prerequisite to building a healthy, productive environment for resilient agri-food systems and livelihoods. Mapping synergies with other Work Packages ensure that respective contributions are integrated and impactful. The process intends to provide policymakers, researchers, and practitioners with a strategic framework to activate solutions temporarily with a stakeholder-defined suite of scenarios.

Soil organic carbon (SOC), a key component of the global carbon (C) pool, plays an important role in C cycling, regulating climate, water supplies and biodiversity, and therefore in providing the ecosystem services that are essential to human well-being. Most agricultural soils in temperate regions have now lost as much as 60% of their SOC, and as much as 75% in tropical regions, due to conversion from natural ecosystems to agricultural uses and mainly due to continuous soil degradation. Sequestering C can help to offset C emissions from fossil fuel combustion and other C-emitting activities, while also enhancing soil quality and long-term agronomic productivity. However, developing effective policies for creating terrestrial C sinks is a serious challenge in tropical and subtropical soils, due to the high average annual temperatures in these regions. It can be accomplished by implementing improved land management practices that add substantial amounts of biomass to soil, cause minimal soil disturbance, conserve soil and water, improve soil structure, and enhance soil fauna activity. Continuous no-till crop production is arguably the best example. These soils need technically sound and economically feasible strategies to sustainably enhance their SOC pools. Hence, this book provides comprehensive information on SOC and its management in different land-use systems, with a focus on preserving soils and their ecosystem services. The only book of its kind, it offers a valuable asset for students, researchers, policymakers and other stakeholders involved in the sustainable development and management of natural resources at the global level.

This book provides a novel approach to governance relating to biodiversity and human well-being in complex tropical landscapes, including forests and protected areas. It focuses attention at the interface between communities and the landscape level, building on interdisciplinary research conducted in five countries (Cameroon, Indonesia, Laos, Madagascar and Tanzania). In each country, the research was set within the framework of a major national policy thrust. The book improves our understanding of and ability to manage complex landscapes---mosaics of differing land uses---in a more adaptive and collaborative way that benefits both the environment and local communities. It includes both single country and cross-site analyses, and focuses on themes, such as resettlement, land use planning, non-timber forest product use and management, the disconnect between customary and formal legal systems, and the role of larger scale policies in local level realities. Chapters also analyze experience with monitoring and a local governance assessment tool. The work also provides guidance for those interested in management and governance at lower and intermediate levels (village, district), scales likely to grow in importance in the global effort to mitigate and adapt to climate change.

Under its program of land investments, the Ethiopian government has leased out huge tracts of land to domestic and foreign investors on terms that are highly favorable to both but particularly to foreign ones. Critical reports on the ibonanzai reaped by foreign capital have appeared in the world media and the websites of international activist organizations, and while some of these are based on questionable evidence, the global attention they have drawn may well be deserved given the image of the country as a land of poverty and hunger. This study, which is based on information gathered from field interviews as well as other sources, looks at the subject from a land rights perspective, with emphasis on the relations of power between small land-users and their communities on the one hand and the state on the other. At bottom what is at stake is the land and the resources on it, and what is being grabbed are rights that in most cases belong to peasant farmers, pastoralists and their communities. In the long run, the shift of agrarian system from small-scale to large-scale, foreign dominated production -which is what the investment program is now doing- will marginalize small producers, and cause immense damage to local ecosystems, wildlife habitats and biodiversity.

This will be the first textbook on the integration of food, energy and water systems (FEWS). In recent years, the world has seen a dramatic rise in interdisciplinary energy and environmental courses and degrees at the undergraduate and graduate levels. In the US for instance, the number and variety of such programs has increased significantly over the past decade, Simultaneously, national and international initiatives that integrate food, energy and water systems have been launched. This textbook provides a substantive introduction to the food-energy-water nexus suitable for use in higher level undergraduate and graduate level courses and for scholars moving into the field of nexus studies without a strong background in all three areas and the many aspects of nexus studies.

Studies in many African countries show that charcoal making is among the primary drivers of deforestation and subsequent land degradation. In the case of Ethiopia, charcoal is produced from state-owned (public) forests and woodlands. There is little regulatory intervention from the government side. Moreover, production is more traditional and the producers have little idea that charcoal can be produced efficiently with modern technologies. Although charcoal meets significant portion of urban households' energy needs in the country, and also support the livelihood of tens of thousands of rural households, it hardly attracted the attention of policy makers and development agents. A good majority of urban population who use charcoal on regular basis doesn't seem to know how charcoal is made, from where it comes, and its adverse environmental impacts. In cognizant of the potential environmental impact of charcoal production and marketing in the country, FSS commissioned this study with the objective to understand the environmental, social and economic implications of charcoal production, marketing and consumption in Ethiopia with aim to generate/increase awareness among the general public and incite a policy debate among concerned key stakeholders.
