Agroforestry systems with a range of native and often neglected and underutilized tree species (NUS) are increasingly recognized for their potential role in restoration, simultaneously providing ecological and livelihood benefits. Successful adoption of these systems requires knowledge about beneficial species, system-level potential profitability, and barriers faced by farmers. Such information is essential but lacking for most NUS. We analyzed the economic potential of NUS in diverse smallholder-managed agroforestry systems in the Peruvian Amazon. Through semi-structured surveys with local stakeholders (n = 40), we identified 10 native Amazonian NUS fruit with ecological, nutritious and commercial benefits. We then simulated the potential revenue per species and system-level profit of an agroforestry system designed with the 10 NUS. Our projections suggest that a diverse NUS-based agroforestry system can outcompete most alternative land-uses in the region on a per hectare profit basis. This shows that including NUS in restoration efforts could provide economic benefits for smallholders. To realize this potential, we recommend adapted interventions, e.g., increased farmer access to planting material, technical support for production and capacity building with a focus on high-potential NUS.

Assessment of existing and preferred agroecological soil, water, and integrated pest management practices in the Makueni and Kiambu Agroecological Living Landscapes, Kenya
This joint assessment survey was conducted in February 2023 and aimed at identifying and evaluating existing practices under three focus areas, soil management, water management, and integrated pest management, in Kiambu and Makueni agroecological living landscapes (ALLs), and assessing farmers’ preferred practices. A total of 80 farmers (40 from each ALL) were interviewed. To arrive at a representative sample of the population’s context, stratified random sampling was carried out using a multi-stage approach using the following five key factors: program and non-program farmers, geography (villages), gender, age, and land size.
Assessing Transitions to Sustainable Agricultural and Food Systems: A Tool for Agroecology Performance Evaluation (TAPE)
There is increasing interest in agroecology as a way to move toward more sustainable agriculture and food systems. However, the evidence of agroecology’s contribution to sustainability remains fragmented because of heterogeneous methods and data, differing scales and timeframes, and knowledge gaps. Facing these challenges, 70 representatives of agroecology-related organizations worldwide participated in the development of the Tool for Agroecology Performance Evaluation (TAPE), to produce and consolidate evidence on the multidimensional performances of agroecological systems. TAPE is composed of: Step 0, the preliminary step that includes a description of the main socio-economic and demographic characteristics of the agricultural and food systems and an analysis of the enabling environment in terms of relevant policy, market, technology, socio-cultural and/or historical drivers; Step 1, the Characterization of Agroecological Transitions (CAET), based on the 10 Elements of Agroecology adopted by FAO and its member countries, using descriptive scales to establish scores and assessing the degree of transition, with information from the farm/household and community/territory scale; Step 2, the Core Criteria of Performance listing the key dimensions considered relevant to address the Sustainable Development Goals (SDGs): Environment & climate change; Health & nutrition; Society & culture; Economy and Governance. Finally Step 3, a participatory validation of the results obtained from the previous steps with the producers and relevant stakeholders. TAPE can be used (i) to assess the extent of agroecological transition among agricultural producers in a community or a territory, (ii) to monitor and evaluate projects by characterizing the initial and subsequent steps in an agroecological transition, and/or (iii) to evaluate widely diverse agricultural systems against agroecological elements and how they contribute to the achievement of the SDGs. Its application can support the transition of all forms of agricultural systems toward more sustainable practices and the formulation of adequate policies to enable this transformation. Preliminary results from pilot applications show that TAPE can perform in a variety of geographic regions and agroecosystems and that it allows assessment of performances of various criteria that move beyond classic indicators to begin to build a global evidence base for agroecology and support transformation to sustainable agricultural production and food systems. © Copyright © 2020 Mottet, Bicksler, Lucantoni, De Rosa, Scherf, Scopel, López-Ridaura, Gemmil-Herren, Bezner Kerr, Sourisseau, Petersen, Chotte, Loconto and Tittonell.
COVID-19 Pandemic and Agroecosystem Resilience: Early Insights for Building Better Futures
The way the COVID-19 pandemic disrupted human lives and livelihoods constituted a stress test for agroecosystems in developing countries, as part of rural–urban systems and the global economy. We applied two conceptual schemes to dissect the evidence in peer-reviewed literature so far, as a basis for better understanding and enabling ‘building back better’. Reported positive impacts of the lockdown ‘anthropause’ on environmental conditions were likely only short-term, while progress towards sustainable development goals was more consistently set back especially for social aspects such as livelihood, employment, and income. The loss of interconnectedness, driving loss of assets, followed a ‘collapse’ cascade that included urban-to-rural migration due to loss of urban jobs, and illegal exploitation of forests and wildlife. Agricultural activities geared to international trade were generally disrupted, while more local markets flourished. Improved understanding of these pathways is needed for synergy between the emerging adaptive, mitigative, transformative, and reimaginative responses. Dominant efficiency-seeking strategies that increase fragility will have to be re-evaluated to be better prepared for further pandemics, that current Human–Nature interactions are likely to trigger.
The effects of agroecological farming systems on smallholder livelihoods: a case study on push–pull system from Western Kenya
There is a need for scaling-up agroecology to promote sustainable agriculture at global level. Although, recent studies show that agroecological approaches can achieve both high yields and profits compared with conventional systems, the performance of other socioeconomic indicators remains unknown. This study has two objectives (i) identify the main characteristics of small-scale producers who represent the target-groups of the SDG 2; (ii) provide a comparison between push–pull and conventional farming systems of maize production to explore and possibly implement sustainable systems. In collaboration with Biovision Africa Trust, a participatory assessment framework was implemented in Western Kenya. Twenty-three farmers were selected and data were analysed showing that the push–pull contributes to social/cultural and natural/ecological capitals. In particular, push–pull farmers are more focused on socially oriented groups (75%); moreover, they cultivate smaller plots (1.9 ha) compared to conventional farmers (3.1 ha) without showing a reduction in profitability. The benefits of adopting push–pull system indicated by farmers (e.g. diminished Striga weed) are consistent with the advantages reported in relevant scientific literature. Considering the explorative nature of this study, the article makes a key contribution by pointing towards important questions for future research on agroecology in Sub-Saharan African countries.
Putting value chain development into perspective: Evolution, blind spots and promising avenues
Donors, NGOs, and government agencies have long embraced market-based development approaches for achieving economic growth and poverty reduction. Over the past two decades, value chain development (VCD) has taken the lead among such approaches. This chapter reviews the evolution of these approaches since the 1980s, with emphasis on the contributions and interactions of researchers and practitioners. Adopting the lens of ‘issue-attention cycles’, we show how 1) excitement is built up over a given approach, funding becomes available, and proliferation kicks in; 2) disenchantment follows as awareness builds on the complexity, trade-offs, and resources required to address these; and 3) interest declines, funding sources dry up, and attention moves to new (or rebranded) approaches. Researchers have spurred these cycles by coining new terms, designing tools, and assessing impact, with limited accountability for VCD outcomes. Practitioners, in turn, have promoted own VCD frameworks and tools and trumpeted their success in implementation, while showing limited appetite for scrutiny. More impactful VCD will require productive interactions between researchers, practitioners, and funding agencies, lasting presence on the ground for supporting smallholders and SMEs, and safe spaces for (self-)critical reflection. Review of what has worked in previous cycles, and what has not, is needed to build on proven elements of VCD approaches while addressing evident shortcomings. Shared commitment to continuous improvement with a long-term view and evidence-based achievements will extend the length of issue-attention cycles, if not eliminate them altogether.
Ethnicity Differences in Uses and Management Practices of Bitter Kola Trees (Garcinia kola) in Cameroon
Bitter kola (Garcinia kola) is an indigenous multipurpose tree species in West and Central Africa, threatened by overexploitation and classified by the IUCN as vulnerable. Understanding local knowledge and management patterns in different socioecological contexts could contribute to designing strategies for conservation and long-term use of the species. In order to characterize the parts of the plant and the harvesting techniques that are used by different ethnic groups in Cameroon, we conducted surveys through the use of semi-structured questionnaires (N = 182) in six different sites covering different agro-ecological zones where the species is present (forest and savanna). Ethnic groups from the savanna agro-ecological zone shared similar patterns in G. kola organs/parts used and harvesting techniques, but these patterns differed among ethnic groups from the savanna and forest zones and within the forest zone. Ethnic groups from the savanna zone mainly harvest the species for its seeds that are used as stimulants. Conversely ethnic groups from the forest zone mainly collect bark and roots, and uses differ between agriculturalists (Fang and Bassa) and hunter-gatherers (Baka). These patterns have direct consequences on species management practices. Savanna farmers applied sustainable harvesting as they extract fruits and seeds and planting more trees in order to increase the species’ contribution to their livelihood. People in the forest zone destructively felled standing trees, threatening the species in its natural environment. The influence of these results on the conservation status of the species in the region are discussed.
Agroecological principles and elements and their implications for transitioning to sustainable food systems. A review
There is consensus that the global food system is not delivering good nutrition for all and is causing environmental degradation and loss of biodiversity, such that a profound transformation is needed to meet the challenges of persistent malnutrition and rural poverty, aggravated by the growing consequences of climate change. Agroecological approaches have gained prominence in scientific, agricultural and political discourse in recent years, suggesting pathways to transform agricultural and food systems that address these issues. Here we present an extensive literature review of concepts, definitions and principles of agroecology, and their historical evolution, considering the three manifestations of agroecology as a science, a set of practices and a social movement; and relate them to the recent dialogue establishing a set of ten iconic elements of agroecology that have emerged from a global multi-stakeholder consultation and synthesis process. Based on this, a consolidated list of principles is developed and discussed in the context of presenting transition pathways to more sustainable food systems. The major outcomes of this paper are as follows. (1) Definition of 13 consolidated agroecological principles: recycling; input reduction; soil health; animal health; biodiversity; synergy; economic diversification; co-creation of knowledge; social values and diets; fairness; connectivity; land and natural resource governance; participation. (2) Confirmation that these principles are well aligned and complementary to the 10 elements of agroecology developed by FAO but articulate requirements of soil and animal health more explicitly and distinguish between biodiversity and economic diversification. (3) Clarification that application of these generic principles can generate diverse pathways for incremental and transformational change towards more sustainable farming and food systems. (4) Identification of four key entry points associated with the elements: diversity; circular and solidarity economy; co-creation and sharing of knowledge; and, responsible governance to enable plausible pathways of transformative change towards sustainable agriculture and food systems. © 2020, The Author(s).
