RESUMEN

Agricultural simplification continues to expand at the expense of more diverse forms of agriculture. This simplification, for example, in the form of intensively managed monocultures, poses a risk to keeping the world within safe and just Earth system boundaries. Here, we estimated how agricultural diversification simultaneously affects social and environmental outcomes. Drawing from 24 studies in 11 countries across 2655 farms, we show how five diversification strategies focusing on livestock, crops, soils, noncrop plantings, and water conservation benefit social (e.g., human well-being, yields, and food security) and environmental (e.g., biodiversity, ecosystem services, and reduced environmental externalities) outcomes. We found that applying multiple diversification strategies creates more positive outcomes than individual management strategies alone. To realize these benefits, well-designed policies are needed to incentivize the adoption of multiple diversification strategies in unison.

RESUMEN

A clear consensus has emerged that innovations are important for adapting to drought and overcoming other biophysical limitations in smallholder farming systems; however, women are notably marginalized from agricultural innovations. We examine whether and how gendered roles and responsibilities shape the adoption and usage of improved wheat varieties and simultaneously uncover opportunities to address and lessen gender-based differences in agricultural innovations. The field data were collected using snowball sampling from seven communities (three in Morocco and four in Uzbekistan) among 574 farmers (half men and half women) of different generations, genders, social statuses, and social classes. Our findings demonstrate how the complex interactions of biophysical constraints, intra-household (spousal and kinship) relations, and the broader macro-level political economy of agriculture converge to influence different identities of women and men farmers' wheat production and processing practices. We argue that without focusing on the socio-cultural factors affecting agriculture, new seed varieties alone cannot address the multifaceted problems confronting farmers in all parts of the world.

RESUMEN

BACKGROUND: Agroecological methods have the potential to impact nutrition and food security, however, to date there is limited research evaluating this approach. OBJECTIVE: A 5-year participatory research project with farming households in north and central Malawi was designed to train farmers on agroecological practices, alongside raising awareness on nutrition and gender equity. This cross-sectional study aimed to explore the relationships between crop diversity, food security at the household level, and individual diversity for women, within the context of an agroecology, nutrition education, and farmer mentoring program. METHODS: Participating farmers were trained in and experimented with different farming methods. These farmers subsequently trained other farmers on these short-term agroecological practices and provided mentorship using community-based educational methods designed to address both household food security and nutrition. In year 4 of the intervention, a cross-sectional survey assessed farm practices, food security, and individual dietary diversity of 851 participating households. RESULTS: Households with lower crop diversity were significantly less likely to be food secure (odds ratios [OR] = 0.829, P < .001). Women in households with higher crop diversity were more likely to have higher individual dietary diversity (OR = 1.120, P < .01), eat vitamin A rich foods (OR = 1.176, P < .01), and legumes, nuts, and seeds (OR = 1.141, P < .01). CONCLUSIONS: These findings suggest that within a participatory agroecological training combined with community-based nutrition education with a focus on social equity, crop diversity is associated with less household food insecurity and poorer diet quality for rural farming households. Crop diversity may improve dietary diversity by making nutritious foods more available.

RESUMEN

Climate change scenarios have significant implications for the livelihoods and food security of particular groups in society and will necessitate a range of adaptation actions. While there is a significant literature on the social as well as biophysical factors and limits to adaptation, less is known about the interactions between these, and what such interactions mean for the prospects of achieving sustainable and resilient food systems. This paper is an attempt at addressing this gap by examining changing biophysical and social factors, with specific consideration of vulnerable groups, across four case studies (Ghana, Malawi, Norway and Spain). In each case, future climate change scenarios and associated biophysical limits are mapped onto four key social factors that drive vulnerability and mediate adaptation, namely, scale, history, power and politics, and social differentiation. We then consider what the interaction between biophysical limits and socio-political dynamics means for the options for and limits to future adaptation, and how climate may interact with, and reshape, socio-political elements. We find that biophysical limits and socio-political factors do not operate in isolation, but interact, with dynamic relationships determining the 'space' or set of options for sustainable adaptation. By connecting the perspectives of biophysical and social factors, the study illuminates the risks of unanticipated outcomes that result from the disregard of local contexts in the implementation of adaptation measures. We conclude that a framework focusing on the space for sustainable adaptation conditioned by biophysical and social factors, and their interactions, can help provide evidence on what does and does not constitute sustainable adaptation, and help to counter unhelpful narratives of climate change as a sole or dominant cause of challenges in food systems.

RESUMEN

Little evidence exists concerning perceptions of anaemia in Ghanaian communities, which limits understanding of how to potentially improve health in settings with high anaemia prevalence. We explored lay perceptions of anaemia to understand local knowledge and beliefs and to provide an opportunity to inform interventions. A cross-sectional, qualitative study was conducted in selected communities in three regions of Ghana with high prevalence of anaemia. Forty-eight focus group discussions (FGDs) were conducted with adolescent girls, adult women of reproductive age and adult men (16 FGDs for each demographic group). Participants across the three demographic groups generally described anaemia as inadequate blood in the body and reported that poor diet, heat, alcohol intake, physiological factors and diseases such as malaria were the main causes of anaemia. Consequences of anaemia mentioned in the FGDs included dizziness, weight loss, loss of appetite and weakness. Prevention of anaemia was perceived to result from improved diet, avoidance of exposure to heat and improved sanitation to avoid diseases. The findings suggest that despite areas of convergence between lay and biomedical knowledge on the causes, consequences and prevention of anaemia, the burden of anaemia remains high in the study regions. This highlights a disconnect between local knowledge of anaemia and the health and nutrition behaviours needed to reduce its incidence. Effective interventions can be developed with and for communities that build upon existing knowledge while filling remaining knowledge gaps or misconceptions.

RESUMEN

The burden of child undernutrition across Africa remains extraordinarily high. Among children under age five, chronic and acute undernutrition is responsible for more ill-health than any other cause. While climate change exacerbates the multiple burdens of undernutrition, we know very little about the embodied effects on women's workload in agriculture and implications for feeding practices, especially for infants whose nutrition depends on mothers' time. In this article, political ecologies of health, with its nested, place-based analysis, is used as a framework to address this knowledge gap. The study took place in Ghana's Upper West Region, a semi-arid and resource-poor setting with higher undernutrition rates. In-depth interviews were conducted with smallholder farmers (n = 33) whose infants have sub-optimal growth, and key informants (n = 7) with expertise in nutrition and health. Findings from the study demonstrate how climate change puts pressure on women's productive time, leading to poor child feeding practices and undernutrition. Ultimately, the article argues that there are hidden impacts of climate change on undernutrition. Global undernutrition interventions should therefore move beyond biomedical solutions to address these hidden impacts, some of which are social, gendered, and structural in nature.

RESUMEN

Although there is a large and growing literature on anticipated climate change impacts on health, we know very little about the linkages between differentiated vulnerabilities to climate extremes and adverse physical and mental health outcomes. In this paper, we examine how recurrent flooding interacts with gendered vulnerability, social differentiation, and place-related historical and structural processes to produce unequal physical and mental health outcomes. We situated the study in Old Fadama, Ghana, using a Photovoice approach (n = 20) and theoretical concepts from political ecologies of health and feminist political ecology. Overall, the study revealed several adverse physical and mental health impacts of flooding, with vulnerability differentiated based particularly on gender and age, but also housing, class, and income. Our findings suggest the need for greater attentiveness to social differentiation in scholarship involving political ecologies of health. The paper builds on the health and place literature by linking the social and contextual to the medical.

RESUMEN

Livestock production and Animal-Source Foods (ASFs) like meat, milk, and eggs are excellent sources of essential micronutrients, including iron and zinc. There is evidence that encouraging increased access to and consumption of these ASFs may either positively or negatively impact anemia, or have no nutritional effects. Drawing upon first-hand experiences in Ghana, this study sought to: (1) identify the main motivations for raising livestock in Ghana; (2) describe the major barriers to consuming ASFs, especially among women of reproductive age (WRA); and (3) explore the feasibility of different livestock-centered interventions to reduce anemia. Key informant interviews and focus group discussions were held with relevant stakeholders at different geographical scales - the national, regional, district, and community levels. The results suggest that livestock enable savings, allow resource-poor households to accumulate assets, and help finance planned and unplanned expenditures (e.g., school fees and illness). Due to these multiple and often pressing uses, direct consumption of home-reared ASFs is not a major priority, especially for poor households. Even when ASFs are consumed, intra-household allocation does not favor women and adolescent girls, demographic groups with particularly high micronutrient requirements. The study participants discussed possible interventions to address these challenges, including (1) increasing livestock ownership through in-kind credit; (2) encouraging nutrition-related behavior change; (3) improving livestock housing; and (4) hatchery management. The paper discusses these interventions based upon potential acceptance, feasibility, cost effectiveness, and sustainability in the Ghanaian context.

RESUMEN

This paper assesses the relationship between agroecology, food security, and human health. Specifically, we ask if agroecology can lead to improved food security and human health among vulnerable smallholder farmers in semi-humid tropical Africa. The empirical evidence comes from a cross-sectional household survey (n=1000) in two districts in Malawi, a small country in semi-humid, tropical Africa. The survey consisted of 571 agroecology-adoption and 429 non-agroecology-adoption households. Ordered logistics regression and average treatment effects models were used to determine the effect of agroecology adoption on self-reported health. Our results show that agroecology-adoption households (OR=1.37, p=0.05) were more likely to report optimal health status, and the average treatment effect shows that adopters were 12% more likely to be in optimal health. Furthermore, being moderately food insecure (OR=0.59, p=0.05) and severely food insecure (OR=0.89, p=0.10) were associated with less likelihood of reporting optimal health status. The paper concludes that with the adoption of agroecology in the semi-humid tropics, it is possible for households to diversify their crops and diets, a condition that has strong implications for improved food security, good nutrition and human health.

RESUMEN

BACKGROUND: In countries where the majority of undernourished people are smallholder farmers, there has been interest in agricultural interventions to improve nutritional outcomes. Addressing gender inequality, however, is a key mechanism by which agriculture can improve nutrition, since women often play a crucial role in farming, food processing and child care, but have limited decision-making and control over agricultural resources. This study examines the approaches by which gender equity in agrarian, resource-poor settings can be improved using a case study in Malawi. METHODS: A quasi-experimental design with qualitative methods was used to examine the effects of a participatory intervention on gender relations. Thirty married couple households in 19 villages with children under the age of 5 years were interviewed before and then after the intervention. An additional 7 interviews were conducted with key informants, and participant observation was carried out before, during the intervention and afterwards in the communities. The interviews were recorded and transcribed, and analysed qualitatively for key themes, concepts and contradictions. RESULTS: Several barriers were identified that undermine the quality of child care practices, many linked to gender constructions and norms. The dominant concepts of masculinity created shame and embarrassment if men deviated from these norms, by cooking or caring for their children. The study provided evidence that participatory education supported new masculinities through public performances that encouraged men to take on these new roles. Invoking men's family responsibilities, encouraging new social norms alongside providing new information about different healthy recipes were all pathways by which men developed new 'emergent' masculinities in which they were more involved in cooking and child care. The transformational approach, intergenerational and intra-gendered events, a focus on agriculture and food security, alongside involving male leaders were some of the reasons that respondents named for changed gender norms. CONCLUSIONS: Participatory education that explicitly addresses hegemonic masculinities related to child nutrition, such as women's roles in child care, can begin to change dominant gender norms. Involving male leaders, participatory methods and integrating agriculture and food security concerns with nutrition appear to be key components in the context of agrarian communities.

RESUMEN

This article shares results from a long-term participatory agroecological research project in northern Malawi. Drawing upon a political ecology of health conceptual framework, the paper explores whether and how participatory agroecological farming can improve food security and nutrition among HIV-affected households. In-depth interviews were conducted with 27 farmers in HIV-affected households in the area near Ekwendeni Trading Centre in northern Malawi. The results show that participatory agroecological farming has a strong potential to meet the food, dietary, labour and income needs of HIV-affected households, whilst helping them to manage natural resources sustainably. As well, the findings reveal that place-based politics, especially gendered power imbalances, are imperative for understanding the human impacts of the HIV/AIDS epidemic. Overall, the study adds valuable insights into the literature on the human-environment dimensions of health. It demonstrates that the onset of disease can radically transform the social relations governing access to and control over resources (e.g., land, labour, and capital), and that these altered social relations in turn affect sustainable disease management. The conclusion highlights how the promotion of sustainable agroecology could help to partly address the socio-ecological challenges associated with HIV/AIDS.
