Uncovering decolonial pedagogies for learning agroecological transitions
Decolonial pedagogies can facilitate agroecological transition processes. • Pedagogical models facilitate agroecological transitions by integrating diverse epistemologies in agriculture practices. • This study identifies three contextual learning narratives: Living, Resistance, and Hybrid Pedagogies. • A main archetype has been discovered, known as the 'South pedagogies archetype'. • The operational decolonial pedagogies framework shows how agroe…
Global analysis of social learning’s archetypes in natural resource management
Although social learning (SL) conceptualization and implementation are flourishing in sustainability sciences, and its non-rigid conceptual fluidity is regarded as an advantage, research must advance the understanding of SL phenomenon patterns based on empirical data, thus contributing to the identification of its forms and triggering mechanisms, particularly those that can address urgent Anthropocene socio-ecological problems. This study aims to…

Sustainable agriculture for health and prosperity
Food systems need to focus more on health, prosperity, and environmental sustainability. This requires changes in what, where, how and by whom food is produced, marketed, and consumed. Interdisciplinary research and trans-disciplinary collaboration are needed. Stakeholders need to agree on their respective roles, values, responsibilities and modus operandi so that research better responds to real-world challenges and opportunities. This viewpoint…
Climate risk management and rural poverty reduction
Climate variability is a major source of risk to smallholder farmers and pastoralists, particularly in dryland regions. A growing body of evidence links climate-related risk to the extent and the persistence of rural poverty in these environments. Stochastic shocks erode smallholder farmers' long-term livelihood potential through loss of productive assets. The resulting uncertainty impedes progress out of poverty by acting as a disincentive to in…
Local dynamics of native maize value chains in a peri-urban zone in Mexico
Building pathways out of poverty through climate smart agriculture and effective targeting
One focus of agricultural development is climate smart agricultural technologies and practices (CSA). Development practitioners invest in scaling these to have wider impact. Ineffective targeting stymies CSA’s contribution to poverty reduction by excluding many of the poor and/or including those for whom agriculture is not a pathway out of poverty. This viewpoint proposes the need to recognise differentiated livelihood pathways within smallholder…
Increasing social-ecological resilience within small-scale agriculture in conflict-affected Guatemala

Maize Diversity, Market Access, and Poverty Reduction in the Western Highlands of Guatemala
The western highlands of Guatemala lie within the area where maize was first domesticated, and maize remains central to farmers' livelihood security. Over 50% of the population in the region are in poverty, and over 48% suffer from chronic malnutrition. Development efforts have focused on improved land management, crop diversification, and improved access to markets, especially for high-value vegetable crops such as snow peas. As a result of succ…
Addressing conflict through collective action in natural resource management
The food security crisis and international “land grabs” have drawn renewed attention to the role of natural resource competition in the livelihoods of the rural poor. While significant empirical research has focused on diagnosing the links between natural resource competition and (violent) conflict, much less has focused on the dynamics of whether and how resource competition can be transformed to strengthen social-ecological resilience and mitig…
Agricultural research organisations' role in the emergence of agricultural innovation systems
Poor farmers seldom benefit from new agricultural technologies. In response, research and extension approaches based on agricultural innovation systems are popular. Often agricultural research organisations are the network brokers, facilitating the emergence of the innovation system. Based on an analysis of the Sustainable Modernization of Traditional Agriculture (MasAgro) initiative in Mexico, this viewpoint suggests that such organisations are …

Impact pathways of trade liberalization on rural livelihoods
Research assessing the impacts of trade liberalization on poor rural populations can be divided intotwo categories: more quantitative research, assessing relationships between specific, measurable variables (such as changes in the macroeconomic environment and their impact on farmers’ income levels); and more qualitative research, which takes trade policy as a context and provides broad, descriptive data about dynamic livelihood strategies. In th…
Planting Hybrids, Keeping Landraces
Maize diversity and gender
In the future, more food will be needed to feed a growing world population. High-yielding crop varieties will play a key role in meeting this challenge. This article draws on research undertaken by the International Maize and Wheat Improvement Center in La Frailesca in the southern Mexican state of Chiapas. Both agricultural and social processes influence women's and men's preferences for new or traditional (local) maize varieties. Despite the ad…
Livelihoods-based impact assessment in the rice-wheat farming system of South Asia
This article reports on an ex-ante impact study in the Indo-Gangetic Plains of South Asia. The study, guided by a livelihoods approach, developed a spatial-mapping methodology based on secondary data for 18 variables which served as indicators of the five livelihood classes of assets (natural, physical, financial, social, and human). The overall livelihood-asset index showed a significant and strong negative correlation (R = –0.65, P = 0.00) with…
Maize diversity, rural development policy, and farmers' practices
Maize diversity is important to the livelihoods of millions of farmers in Mexico, the crop's centre of origin; to maize breeders seeking new genetic material; and to producers and consumers worldwide. Key social processes that determine maize diversity include historic and cultural emphases on maize as a primary crop; land-use practices encompassing heterogeneous agro-ecological conditions; farmers' seed-saving practices; farmer selection of usef…
Maize diversity, poverty, and market access
Crop genetic diversity and poverty are linked: first, resource-poor farmers often maintain genetic diversity; and second, crop diversity, when properly valued by the market, has the potential to alleviate poverty. This article examines this supposition by drawing on three case studies of the intersection of the market with poverty and maize diversity in Mexico. These suggest that the bulk market for maize offers little room for maize landraces (l…
Collective action for smallholder market access
Operationalising participatory research and farmer-to-farmer extension
While rural poverty is endemic in the Andean region, structural adjustment programmes have led to a dismemberment of agricultural research and extension services so that they are unable to serve the needs of smallholder farmers. The NGO Practical Action has been working in the Andes to address farmers' veterinary and agriculture needs. The work has included the training of farmer-to-farmer extension agents, known locally as Kamayoq. The Kamayoq h…
Crop diversity and livelihood security in the andes
Andean farmers have traditionally adapted and selected varieties of quinoa and potatoes to reduce their vulnerability to a range of environmental risks. Data suggest that this strategy is being undermined. Market pressures, particularly the requirements for consistency and quantity along with the import of subsidised wheat products, are leading to the displacement of quinoa and indigenous potato varieties. This paper explores the feasibility of m…
