Abstract
Amid climate change, biodiversity loss and food insecurity, there is the growing need to draw synergies between micro-scale environmental processes and practices, and macro-level ecosystem dynamics to facilitate conservation decision-making. Adopting this synergistic approach can improve crop yields and profitability more sustainably, enhance livelihoods and mitigate climate change. Using spatially explicit data generated through a public participatory geographic information system methodology (n = 37), complemented by spatial analysis, interviews (n = 68) and focus group discussions (n = 4), we explored the synergies between participatory farmer-to-farmer agroecology knowledge sharing, farm-level decisions and their links with macro-level prioritization of conservation strategies. We mapped farm conditions and ecosystem services (ES) of two village areas with varying knowledge systems about farming. Results of the farm-level analysis revealed variations in spatial perception among farmers, differences in understanding the dynamics of crop growth and varying priorities for extension services based on agroecological knowledge. The ES use pattern analysis revealed hotspots in the mapped ES indicators with similarities in both village areas. Despite the similarities in ES use, priorities for biodiversity conservation align with farmers’ understanding of farm processes and practices. Farmers with training in agroecology prioritized strategies that are ecologically friendly while farmers with no agroecology training prioritized the use of strict regulations. Importantly, the results show that agroecology can potentially contribute to biodiversity conservation and food security, with climate change mitigation co-benefits. The findings generally contribute to debates on land sparing and land sharing conservation strategies and advance social learning theory as it pertains to acquiring agroecological knowledge for improved yield and a sustainable environment.

Abstract
Despite increasing land degradation in sub-Saharan Africa, investment in sustainable land management (SLM) remains low. Empirical evidence show that smallholder farmers tend to prioritize investing in SLM practices with short-term turnover—e.g., composting and crop residue integration—in order to improve soil fertility and yields to the neglect of practices like agroforestry whose benefits tend to materialize in a relatively longer period. While it is crucial for farmers to prioritize both short-term and long-term SLM practices for the maintenance of overall ecosystem health, the factors that shape the concurrent adoption of short-term and long-term SLM practices remain underexplored. Using data from a cross-sectional survey with smallholder farming households (n = 512) in Malawi, we employed logistic regression to examine the determinants of the concurrent adoption of short-term and long-term SLM practices. Our findings show that plot size, farmer-to-farmer knowledge sharing, presence of a chronically ill person in the household, active household labor size, wealth and women’s autonomy are noteworthy determinants. A unit increase in plot size was associated with increased odds (OR = 1.41, p < 0.01) of simultaneously adopting short-term and long-term SLM practices. Similarly, a unit increase in the active labor size of the household (OR = 1.30, p < 0.001) was positively associated with the concurrent adoption of short-term and long-term SLM practices. Households with no chronically sick person were 3.2 times more likely to adopt short-term and long-term SLM practices simulataneously compared to those with chronically sick persons. Farming households that exchanged farming information (OR = 2.50, p < 0.001) with other households had significantly higher odds of adopting short-term and long-term SLM practices concurrently than those that did not share farming information. Compared to households in the poorest wealth category, those in the richer (OR = 3.14, p < 0.001) and richest (OR = 3.64, p < 0.001) wealth categories were both significantly more likely to adopt short-term and long-term SLM practices concurrently. These findings suggest that initiatives targeted at promoting the holistic adoption of SLM practices—a combination of both short-term and long-term practices—must pay attention to contextual nuances including household wealth, gender, farmer training and land access dynamics.

Abstract
The role of agroecological practices in addressing food security has had limited investigation, particularly in Sub-Saharan Africa. Quasi-experimental methods were used to assess the role of agroecological practices in reducing food insecurity in small- holder households in Malawi. Two key practices – crop diversi- fication and the incorporation of organic matter into soil – were examined. The quasi-experimental study of an agroecological intervention included survey data from 303 households and in- depth interviews with 33 households. The survey sampled 210 intervention households participating in the agroecological intervention, and 93 control households in neighboring villages. Regression analysis of food security indicators found that both agroecological practices significantly predicted higher food security and dietary diversity for smallholder households: the one-third of farming households who incorporated legume residue soon after harvest were almost three times more likely to be food secure than those who had not incorporated crop residue. Qualitative semi-structured interviews with 33 house- holds identified several pathways through which crop diversifi- cation and crop residue incorporation contributed to household food security: direct consumption, agricultural income, and changes in underlying production relations. These findings pro- vide evidence of agroecology’s potential to address food inse- curity while supporting sustainable food systems.

Abstract
The pivotal role of social capital in smallholder agriculture is widely acknowledged. The growth effect of social capital manifests in how networks and trust facilitate access to productive resources and knowledge sharing among farmers. While sub-Saharan Africa is considered a storehouse of rich social capital, recent literature indicates its rapid depletion due mainly to the rise of capitalist agriculture and concomitant reorganization of the relations of production that characterize smallholder agriculture. Agroecology is an alternative approach to agriculture aimed at addressing the adverse impacts of capitalist agriculture, including improving farmer-to-farmer networks. In this paper, we draw on longitudinal data from a five-year participatory agroecology intervention in Malawi using Difference-in-Difference (DID) to compare the social capital endowment of agroecology-practicing households (n = 514) and a control group of non-agroecology households (n = 400). We further employed linear regression to examine the relationship between social capital and agroecology adoption. Results from the DID analysis show a positive and statistically significant change in mean social capital for participatory agroecology households (β = 0.325, p< 0.001) compared to non-agroecology households (β = 0.108) after accounting for theoretically relevant factors. Overall, the average treatment effect of the intervention on social capital was positive (β = 0.217, p< 0.01). We also found a bidirectional relationship between social capital and adoption of agroecology practices (β = 0.12, p< 0.001). These findings reveal the positive inroads of agroecology beyond the farm-level and demonstrate the potential for policymakers to leverage these benefits to promote sustainable agriculture.

Abstract

This study examines whether agroecological farming practices, when employed by highly vulnerable households in sub-Saharan Africa, can improve food security and dietary diversity. The research involved a four-year study with 425 smallholder households, selected purposively based on high levels of food insecurity and/or positive HIV status. The households carried out agroecological experiments of their own choosing over a four-year period. Baseline (n = 306) and follow-up (n = 352) surveys were conducted in 2011 and 2013 respectively to assess changes in farming practices, food security, crop diversity and dietary diversity. Longitudinal mixed effects models were used with 203 matched households to estimate determinants of change in food security and dietary diversity at the population level. Qualitative interviews and focus groups were also conducted to provide depth to the survey findings. The findings show that participatory agroecology experimentation increased intercropping, legume diversification and the addition of compost, manure and crop residue amendments to the soil. Intercropping was associated with food security and the use of organic soil amendments was associated with gains in dietary diversity in bivariate analysis. Household food security and dietary diversity increased significantly over a 2-year period. Importantly, multivariate models showed that spousal discussion about farming was strongly associated with increased household food security and dietary diversity. Households who discussed farming with their spouse were 2.4 times more likely to be food secure and have diverse diets. Addition of compost or manure to the soil significantly influenced dietary diversity. These findings indicate that poor, vulnerable farmers can use agroecological methods to effectively improve food and nutritional security in sub-Saharan Africa. The study also highlights how linking agroecology to participatory research approaches that promote farmer experimentation and gender equity also lead to greater health and well-being. The study sheds light on how agroecological approaches can rapidly improve food security and dietary diversity, even under conditions of acute social, health or ecological stress. It draws attention to issues of equity and farmer-led approaches in addressing food security and nutrition.

Repairing rifts or reproducing inequalities? Agroecology, food sovereignty, and gender justice in Malawi (2019)

Abstract

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.

Abstract

How to engage farmers that have limited formal education is at the foundation of environmentally-sound and equitable agricultural development. Yet there are few examples of curricula that support the co-development of knowledge with farmers. While transdisciplinary and participatory techniques are considered key components of agroecology, how to do so is rarely specified and few materials are available, especially those relevant to smallholder farmers with limited formal education in Sub-Saharan Africa. The few training materials that exist provide appropriate methods, such as compost making, but do not explain relationships and synergies between nutrition, social inequalities, climate change and agroecology. Some food sovereignty and agroecology courses aim at popular political education for those with more formal education. Here we describe the process of development of an innovative curriculum, which integrates agroecology, nutrition, climate change, gender and other dimensions of social equity across 2 weeks of training explicitly for smallholders in southern Africa with limited formal education. The curriculum is highly participatory; we use concepts in popular education, transformative and experiential-based learning, and theatre. It is also integrative; we link agroecology with climate change, human and soil nutrition, gender, and related components of social equity. Developed in partnership with Malawian farmers, community development experts and academics from five countries, the curriculum was piloted with 520 smallholder farming households in Malawi and Tanzania, and evaluated using qualitative techniques. Clashes of language, cultural norms, and terminology were as great of a challenge as agreeing on and conveying technical information, to weave into a coherent whole. However, farmers who participated in the curriculum training demonstrated high interest, comprehension of material and interest in immediate application to their lives.
