In this article I use the concept of the Plantationocene to discuss contrasting contemporary narratives and practices-namely agroecology versus sustainable intensification. Drawing on long-term ...research in Malawi, I use the concepts of the plantation imaginary as well as the plot to consider the potential for decolonializing agrarian futures in Africa. I argue that sustainable intensification narratives are a type of plantation imaginary that mobilizes images and ideas of African agrarian knowledge as backward, and African women farmers overburdened, to be saved by modern technology and science. Feminist agroecology can be viewed as a form of plot that allows for new ways of farming and being in communities that is a kind of decolonial thinking.
This paper argues that large-scale land appropriation is displacing subsistence farmers and reworking agrarian social relations in northern Ghana. The recent wave of farmland enclosure has not only ...resulted in heightened land scarcity, but also fostered a marked social differentiation within farming communities. The dominant form of inequality is an evolving class of landless and near-landless farmers. The majority of households cope with such dynamics by deepening their own self-exploitation in the production process. The fulcrum of this self-exploitation is gendered property rights as part of the conjugal contract, with men exerting a far greater monopoly over land resources than had previously been the case. Due to acute land shortages, women's rights to use land as wives, mothers and daughters are becoming insecure, as their vegetable plots are being reclassified as male-controlled household fields. The paper further documents the painful choices that landless farmers have to make in order to meet livelihood needs, including highly disciplined, yet low-waged, farm labor work and sharecropping contracts. In these livelihood pathways, there emerge, again, exploitative relations of production, whereby surplus is expropriated from land-dispossessed migrant laborers and concentrated with farm owners. These dynamics produce a 'simple reproduction squeeze' for the land-dispossessed. Overall, the paper contributes to the emerging land grabbing literature by showing geographically specific processes of change for large-scale mining operations and gendered differentiated impacts.
There are urgent calls for the transformation of agriculture and food systems to address human and planetary health issues. Nutrition-sensitive agriculture and agroecology promise interconnected ...solutions to these challenges, but evidence of their impact has been limited.
In a cluster-randomized trial (NCT02761876), we examined whether a nutrition-sensitive agroecology intervention in rural Tanzania could improve children's dietary diversity. Secondary outcomes were food insecurity and child anthropometry. We also posited that such an intervention would improve sustainable agricultural practices (e.g., agrobiodiversity, intercropping), women's empowerment (e.g., participation in decision making, time use), and women's well-being (e.g., dietary diversity, depression).
Food-insecure smallholder farmers with children aged <1 y from 20 villages in Singida, Tanzania, were invited to participate. Villages were paired and publicly randomized; control villages received the intervention after 2 y. One man and 1 woman “mentor farmer” were elected from each intervention village to lead their peers in agroecological learning on topics including legume intensification, nutrition, and women's empowerment. Impact was estimated using longitudinal difference-in-differences fixed-effects regression analyses.
A total of 591 households (intervention: n = 296; control: n = 295) were enrolled; 90.0% were retained to study end. After 2 growing seasons, the intervention improved children's dietary diversity score by 0.57 food groups (out of 7; P < 0.01), and the percentage of children achieving minimum dietary diversity (≥4 food groups) increased by 9.9 percentage points during the postharvest season. The intervention significantly reduced household food insecurity but had no significant impact on child anthropometry. The intervention also improved a range of sustainable agriculture, women's empowerment, and women's well-being outcomes.
The magnitude of the intervention's impacts was similar to or larger than that of other nutrition-sensitive interventions that provided more substantial inputs but were not agroecologically focused. These data suggest the untapped potential for nutrition-sensitive agroecological approaches to achieve human health while promoting sustainable agricultural practices.
Food systems, which are complex, including everything from production, processing, distribution, consumption, and waste, and involve many different groups and institutions, are under increasing ...pressure to adapt to climate change. Maladaptation, which has been increasingly observed and documented in the scientific literature, is defined as an action that 1) generates or increases climate risk, 2) exacerbates vulnerability, 3) erodes sustainable development, or 4) contributes to greenhouse gas emissions. Maladaptive actions can occur to those implementing the action, or transfer negative effects on those not considered by the actual intervention, including at the global scale. In this paper, I review the current literature on maladaptation in food systems, provide examples from the literature of different types of maladaptive outcomes in food systems, and the literature on how to prevent maladaptation.
•Increasing evidence of maladaptation in agriculture and food systems.•Agricultural intensification strategies often have maladaptive impacts.•Adverse environmental, social, political, health, and well-being impacts.•To avoid maladaptation, consider different scales, timeframes, and trade-offs .•Planning processes that address power inequities important to prevent maladaptation.
Climate change research is at an impasse. The transformation of economies and everyday practices is more urgent, and yet appears ever more daunting as attempts at behaviour change, regulations, and ...global agreements confront material and social-political infrastructures that support the status quo. Effective action requires new ways of conceptualizing society, climate and environment and yet current research struggles to break free of established categories. In response, this contribution revisits important insights from the social sciences and humanities on the co-production of political economies, cultures, societies and biophysical relations and shows the possibilities for ontological pluralism to open up for new imaginations. Its intention is to help generate a different framing of socionatural change that goes beyond the current science-policy-behavioural change pathway. It puts forward several moments of inadvertent concealment in contemporary debates that stem directly from the way issues are framed and imagined in contemporary discourses. By placing values, normative commitments, and experiential and plural ways of knowing from around the world at the centre of climate knowledge, we confront climate change with contested politics and the everyday foundations of action rather than just data.
This Malawi study examines whether agroecology can be effectively used by smallholders to address food sovereignty. We build on the concept of the metabolic rift, arguing that repairing this rift ...includes social relations. Agroecological methods can be important strategies, but are labour and knowledge intensive, and require addressing power dynamics within and beyond households in order to address food sovereignty. The case study included participatory methods of dialogue, experimentation and horizontal learning to foster change. We argue that feminist concepts of intersectionality and participatory praxis are central to mobilizing agroecology to build food sovereignty and work to transform social relations.
Mapping crop types and land cover in smallholder farming systems in sub-Saharan Africa remains a challenge due to data costs, high cloud cover, and poor temporal resolution of satellite data. With ...improvement in satellite technology and image processing techniques, there is a potential for integrating data from sensors with different spectral characteristics and temporal resolutions to effectively map crop types and land cover. In our Malawi study area, it is common that there are no cloud-free images available for the entire crop growth season. The goal of this experiment is to produce detailed crop type and land cover maps in agricultural landscapes using the Sentinel-1 (S-1) radar data, Sentinel-2 (S-2) optical data, S-2 and PlanetScope data fusion, and S-1 C2 matrix and S-1 H/α polarimetric decomposition. We evaluated the ability to combine these data to map crop types and land cover in two smallholder farming locations. The random forest algorithm, trained with crop and land cover type data collected in the field, complemented with samples digitized from Google Earth Pro and DigitalGlobe, was used for the classification experiments. The results show that the S-2 and PlanetScope fused image + S-1 covariance (C2) matrix + H/α polarimetric decomposition (an entropy-based decomposition method) fusion outperformed all other image combinations, producing higher overall accuracies (OAs) (>85%) and Kappa coefficients (>0.80). These OAs represent a 13.53% and 11.7% improvement on the Sentinel-2-only (OAs < 80%) experiment for Thimalala and Edundu, respectively. The experiment also provided accurate insights into the distribution of crop and land cover types in the area. The findings suggest that in cloud-dense and resource-poor locations, fusing high temporal resolution radar data with available optical data presents an opportunity for operational mapping of crop types and land cover to support food security and environmental management decision-making.
Family and cultural contexts can constrain the effectiveness of evidence-based interventions designed to improve the health and wellbeing of women and their children. Unequal power relationships ...within the household may underlie the failure of many programs targeting women to achieve their intended impact. To reduce these unequal power dynamics within the households, many programs or interventions aim to both assess and improve the gender dynamics between husbands and wives within the household. Decision-making is one important facet of these dynamics and has been linked to health outcomes for women and children. However, household decision-making is rarely observed and often difficult to capture. This study aimed to use qualitative research to further understand one aspect of decision-making, namely on how to spend money. In two regions of Tanzania, we used surveys and interviews to explore different perspectives on spending and allocation of resources among 58 couples in rural farming households. While many men and women initially reported that they made decisions jointly, most women stated they would often concede if there was a disagreement or argument around spending. These results highlight the different perceptions of joint decision-making between men and women. We compared these results to survey responses on decision-making and found differences within and between couples across interview and survey responses. Based on the differences in qualitative and survey responses within couples and how they reported dealing with disagreement, our study found households were on a spectrum from no cooperation in decision-making to full cooperation. Our results highlight challenges for assessing decision-making on spending and ultimately improving these decision-making dynamics within the household. These challenges are especially important for maternal and child behavioral change and provide insights on why many interventions aimed at improving women’s decision- making power on money may not reach their full potential.
Human-induced land degradation currently threatens the livelihoods of over 3 billion people globally. While Sustainable Land Management (SLM) has emerged as a widely accepted approach for addressing ...land degradation in agroecosystems, the use of SLM practices remains low among smallholder farmers. Empirical research points to the potentially beneficial role of participatory farmer-to-farmer (F2F) training and knowledge sharing in improving SLM in resource-poor contexts. Drawing theoretical insights from social learning and using cross-sectional data from an agroecology intervention with smallholder farming households in Malawi (n = 609 farming households, comprising 463 households that received F2F training in agroecology and 146 households that did not receive F2F training), we examine the association between participatory agroecology training and the adoption of SLM practices. Findings from tobit regression analysis show that F2F training was positively associated with the use of SLM practices (β = 0.04 p < 0.05) two years following the intervention after accounting for demographic, agricultural and socioeconomic factors. These findings contribute to a growing body of literature that demonstrates the potential of participatory F2F training to improve the uptake and maintenance of SLM technologies. In the context of resource constraints and the associated low agricultural extension in sub-Saharan Africa, participatory F2F training may offer a cost-effective way to reach a wide range of smallholder farmers to promote the use of SLM practices.
•Farmers with F2F agroecology training were significantly more likely to use SLM.•F2F helps sustain impacts: farmers used SLM practices 2+ years after intervention.•Participatory F2F agroecology is viable areas of high land degradation.
Following a decade of declining food insecurity, the global undernourished population has increased successively in the last three years. This increasing trend highlights the challenge of meeting the ...zero hunger and nutrition targets of Sustainable Development Goal (SDG) 2. Malawi is one of the most food insecure countries in Africa, with a significant proportion of its population being undernourished. Amid evidence of the counter-productive effects of input-intensive agriculture in this context, including the narrowing of the food basket and unequal access to subsidized inputs, some scholars have argued that alternative diversified agricultural approaches, combined with attention to underlying inequalities, maybe more promising in addressing undernutrition. Agroecology is one such approach which promotes biodiversity and pays attention to socio-political inequalities. That notwithstanding, there is limited research on the potential role of agroecology in improving household food outcomes. Drawing theoretical insights from political ecology and using Difference-in-Difference and mediation techniques, we examine the impact of agroecology on household production diversity and dietary diversity using data from a five-year agroecological intervention in Malawi (n = 514 agroecology-practicing farming households and 400 non-agroecology households). Findings from the Difference-in-Difference analysis show a positive treatment effect of agroecology on both production diversity (β = 0.289, p < 0.01) and dietary diversity (β = 0.390, p < 0.01). Results from the mediation analysis indicate that generally, production diversity is directly associated with dietary diversity (β = 0.18, p < 0.01), although the relationship is stronger for households practicing agroecology (β = 0.19, p < 0.01) compared to non-agroecology households (β = 0.14, p < 0.01). These findings provide evidence of the potential for agroecology to improve nutrition in smallholder farming contexts and contribute to achieving SDGs 2. Malawi is currently grappling with widespread micronutrient deficiencies. Given that smallholder farmers typically draw a significant proportion of their diet from what they produce, farming approaches like agroecology, which emphasizes the cultivation of diverse crops, may be promising for improving household nutrition.
