Visions of sustainable development and the future of smallholder farmers in sub-Saharan Africa (and beyond)

Smallholder farmers are widely touted as essential to sustainable agricultural development in sub-Saharan Africa and beyond. But what exactly is meant by sustainable development, and how are smallholder farmers expected to contribute to it? In this perspective, we describe and assess two competing visions of sustainable development, namely Capital Theory and the Capabilities approach, paying special attention to the major yet divergent repercussions each approach implies for the future of smallholder farmers and the activities of their representative organizations. We present the core concepts, tools and practices stemming from each sustainable development perspective, and from a critique of these motivate the superiority of a capabilities approach as more conducive to smallholder farmers wellbeing now and in the future. In doing so, we bring to the fore the pivotal role smallholder farmer organizations and rural social movements, as collective vehicles for smallholder political agency, play in strategically advocating for the conditions that support sustainable and just smallholder agriculture in sub-Saharan Africa and beyond.

Investigating the impact of credit channels, energy production and oil revenues on agricultural development in sub-Saharan Africa

Development of the agricultural sector can numerously gift the economy by ensuring food security and rural livelihoods, fostering economic growth, reducing poverty, promoting social stability, and achieving sustainable development goals. But agricultural activities especially in Sub-Saharan Africa are faced with numerous challenges like lack of required credits to the farmers, unavailability of needed energy for powering the farm machinery and transportation of farm produce, and fluctuation of crude oil prices which serve as the main source of energy in Sub-Saharan Africa. However, the sequel to these highlighted challenges that face agricultural activities, this study examines the impact of credit channels, energy production, and oil revenue on agricultural development in sub-Saharan Africa using an annual time series covering 21 years (2001–2021) drawn from selected sub-Saharan African countries under study. Using the panel autoregressive distributed lag model (ARDL) as the baseline model and the generalized method of moment (GMM) as the robustness check, we made the following findings. From the ARDL perspective, we found that credit channels have a negative impact on agricultural development. In contrast, energy production and oil revenue have positive and negative significant impacts on the agricultural development of sub-Saharan Africa. Further, results of the Generalized Method of Moment (GMM) revealed that while credit channels have both negative and positive long-run relationships with agricultural development, energy production, and oil revenues have positive and significant long-run relationships with agricultural development in sub-Saharan Africa. The study concludes that credit channels have both negative and positive long-run relationships with agricultural development. In contrast, energy production and oil revenue have negative and significant long-run relationships with agricultural development in sub-Saharan Africa. We recommended effective agricultural credit provision and a mechanized farming system to increase the quality and quantity of food supplies in sub-Saharan Africa.

Impact of Livestock Insurance Schemes on Smallholder Farmers’ Resilience to Climate Change in Sub-Saharan Africa

Purpose: This study sought to investigate the impact of livestock insurance schemes on smallholder farmers’ resilience to climate change in Saharan Africa. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to the impact of livestock insurance schemes on smallholder farmers’ resilience to climate change in Saharan Africa. Preliminary empirical review revealed that livestock insurance schemes significantly enhanced the resilience of smallholder farmers to climate change in Sub-Saharan Africa by providing financial protection against climate-induced livestock losses, maintaining livestock assets, and stabilizing household incomes during climatic shocks. However, barriers such as high premium costs, limited awareness, and distrust in insurance providers hindered widespread adoption. Recommendations included premium subsidies, extensive education programs, and improved transparency to increase uptake. Integrating insurance with broader risk management strategies was also emphasized to maximize resilience benefits. Unique Contribution to Theory, Practice and Policy: The Theory of Planned Behaviour (TPB), Protection Motivation Theory (PMT) and Resource Dependence Theory (RDT) may be used to anchor future studies on livestock insurance schemes on smallholder farmers’ resilience to climate change. The study recommended integrating socio-economic factors into theoretical frameworks, enhancing practical training and capacity-building for farmers, and creating supportive regulatory policies to improve the adoption of livestock insurance schemes. It emphasized the importance of integrating insurance with broader risk management strategies, leveraging technological innovations to enhance accessibility, and conducting continuous monitoring and evaluation to ensure the schemes' effectiveness. These recommendations aimed to enhance smallholder farmers' resilience to climate change, maximize the benefits of livestock insurance, and ensure sustainable agricultural development in Sub-Saharan Africa.

Crop yields fail to rise in smallholder farming systems in sub-Saharan Africa

Drawing on a harmonized longitudinal dataset covering more than 55,000 smallholder farms in six African countries, we analyze changes in crop productivity from 2008 to 2019. Because smallholder farmers represent a significant fraction of the world's poorest people, agricultural productivity in this context matters for poverty reduction and for the broader achievement of the UN Sustainable Development Goals. Our analysis measures productivity trends for nationally representative samples of smallholder crop farmers, using detailed data on agricultural inputs and outputs which we integrate with detailed data on local weather and environmental conditions. In spite of government commitments and international efforts to strengthen African agriculture, we find no evidence that smallholder crop productivity improved over this 12-y period. Our preferred statistical specification of total factor productivity (TFP) suggests an overall decline in productivity of -3.5% per year. Various other models we test also find declining productivity in the overall sample, and none of them finds productivity growth. However, the different countries in our sample experienced varying trends, with some instances of growth in some regions. The results suggest that major challenges remain for agricultural development in sub-Saharan Africa. They complement previous analyses that relied primarily on aggregate national statistics to measure agricultural productivity, rather than detailed microdata.

Every farmer is a farmer? A critical analysis of the emergence and development of Peasant Farmers Association of Ghana

Smallholder farmer-based rural social movements have been heralded as a promising source of political power with the potential to effectively promote sustainable trajectories of agricultural development in Sub-Saharan Africa and beyond. However, the very early stages of rural social movement building remain understudied, including under what conditions such nascent efforts are likely to lead to effective political influence and foundations for broader collective action. Drawing on insights from organizational studies and resource mobilization theories, we provide an analytical narrative of the emergence and development of a smallholder farmer-based policy advocacy organization, the Peasant Farmers Association of Ghana (PFAG). Through analysis of organizational documents and an extensive open-ended focus group interview with PFAG’s founders, long-term members, and current staff, we discuss how PFAG managed to overcome the “liability of newness” faced by new organizations, and how its resulting organizational structure influences its modes of resource mobilization and thus type and coverage of its advocacy and service delivery activities. Considering this developmental narrative, we elaborate several challenges that PFAG faces in pursuit of its ambitions to expand its influence in Ghanaian agricultural policy and practice. Our findings indicate the need for PFAG to address emerging contradictions in project activities and uneven geographical coverage, manage tensions between advocacy and service delivery objectives and to work towards establishing an umbrella agenda capable of providing for the diverse and evolving needs of their membership base.

Prioritizing conservation in sub-Saharan African lakes based on freshwater biodiversity and algal bloom metrics.

As agricultural land use and climate change continue to pose increasing threats to biodiversity in sub-Saharan Africa, efforts are being made to identify areas where trade-offs between future agricultural development and terrestrial biodiversity conservation are expected to be greatest. However, little research so far has focused on freshwaterbiodiversity conservation in the context of agricultural development in sub-Saharan Africa. We aimed to identify lakes and lake areas where freshwater biodiversity is most likely to be affected by eutrophication and Harmful Algal Blooms (i.e., when algae multiply to the extent that they have toxic effects on people and freshwater fauna), some of the most important emerging threats to freshwater ecosystems worldwide, especially with the onset of climate change. Using novel remote-sensing techniques, we identified lakes that demonstrated high biodiversity and algal bloom levels. We calculated the richness of freshwater species and the normalized difference chlorophyll index (NDCI) to prioritize lakes in Ghana, Ethiopia, Zambia, and bordering countries, of high priority for conservation. We identified 169 priority lakes and lake areas for conservation, based on high levels of biodiversity exposed to potentially harmful algal blooms. Zambia had the most lakes identified as conservation priorities (76% of its small lakes and five 100-km2 areas in large lakes). Many of the conservation priority lakes and lake areas identified in this study were in transboundary watersheds; thus, collaborative water resource management and conservation at the watershed scale is needed. The use of remote-sensing tools to prioritize freshwater systems for conservation according to algal-bloom risk is vital in remote, undersampled world regions, especially given the increasing threat posed to freshwater biodiversity by rapidly expanding agriculture and climate change.

Revisiting Rwanda’s agricultural intensification policy: benefits of embracing farmer heterogeneity and crop-livestock integration strategies

The government of Rwanda is promoting agricultural intensification focused on the production of a small number of targeted commodities as a central strategy to pursue the joint policy goals of economic growth, food security and livelihood development. The dominant approach to increase the productive capacity of the land, crops and animal resources has been through large-scale land consolidation, soil fertility management, and the intensive use of biotechnology and external inputs. However, evidence has shown that many Rwandan farmers, who employ various strategies and mixed farming practices based on their specific economic, social, and environmental circumstances, face difficulties adopting the singular prescribed approach to become more productive, modern commodity producers. To empirically explore diversity in smallholders’ strategies and their contributions to livelihoods and compatibility with the recent intensification policies, we conducted household surveys and in-depth qualitative interviews in rural and peri-urban zones in Rwamagana district in Eastern Rwanda. Our analysis demonstrates how the dominant approach to intensification and specialisation overlooks the heterogeneity and dynamic nature of smallholder strategies. Moreover, our findings illustrate that a comprehensive understanding of farmer heterogeneity is necessary to explain the critical disjuncture between the government’s vision of modern agriculture and the ability of many smallholders to engage with this agenda and may inform opportunities to adapt policies to better align productivity goals and livelihoods. In doing so, we contribute to debates about the current framing of intensification policy that promotes Green Revolution technologies and emphasise alternative pathways for more inclusive and resilient agricultural development in sub-Saharan Africa.

A Systematic Review of Drivers and Constraints on Agricultural Expansion in Sub-Saharan Africa

Understanding the dynamics of agricultural expansion, their drivers, and interactions is critical for biodiversity conservation, ecosystem-services provision, and the future sustainability of agricultural development in Sub-Saharan Africa (SSA). However, there is limited understanding of the drivers of agricultural expansion. A systematic review of the drivers of agricultural expansion was conducted from 1970 to 2020 using Web of Science, Elsevier Scopus and Google Scholar. Two researchers reviewed the papers separately based on inclusion and exclusion criteria. Fifteen papers were included in the final systematic review. The paper proposed expansion pathways in a conceptual framework and identified proximate and underlying drivers. Population dynamics and government policies were found to be key underlying drivers of agricultural expansion. The proximate drivers include economic opportunities such as agriculture mechanisation and cash crops production, and more troubling trends such as soil fertility decline and climate change and variability. This paper further explores the constraints that have been found to slow down agricultural expansion, including strong land institutions and good governance.

Public-private cooperation and agricultural development in Sub-Saharan Africa: a review of Nigerian growth enhancement scheme and e-voucher program

The Growth Enhancement Scheme and e-voucher program, rolled out across Nigeria in 2011 by the federal government, provided the institutional basis for private agro-dealers to engage in the distribution of subsidized fertilizer, improved seeds and extension services to farmers. However, the impact of this policy on different modes of extension service delivery is still missing in literature. We apply an Ordinary Least Squared and Difference-in-Difference methodology on the (2010 and 2012) Living Standard Measurement Study of the World Bank. The results suggest that extension visitations as well as public extension services positively influence farm revenue. Furthermore, a substantial increase in fertilizer expenditure by farmers was observed, due to the e-voucher program, which could have contributed to the improved agricultural output witnessed in Nigeria post-Growth Enhancement Scheme era. Governments across Sub-Saharan Africa should implement policies that harness the economy of scale and scope of the private sector as well as information and communication technologies in delivering on time and adequate agricultural inputs to farmers.

Farmer-to-farmer digital network as a strategy to strengthen agricultural performance in Kenya: A research note on ‘Wefarm’ platform

The potential to utitilize mobile phone innovations in providing customized agricultural information and services to improve smallholder farmers’ performance in sub-Saharan Africa (SSA) remains largely untapped. This is at the backdrop of the increasing emergence and adoption of ICT services as a means of relaying agricultural information to small-scale farmers and extension workers. One such technology is ‘Wefarm’ in Kenya, an SMS-based knowledge-sharing platform that enables farmers to connect with their peers and exchange knowledge about their production systems. Even though targeted to improve farmers’ access to information related to agricultural production, marketing and financial services, the extent to which these goals are achieved has not been evaluated. A pathway to improve technology adoption is by proving that the technology can enable farmers to attain their livelihood objectives. This short research note, therefore, identifies critical knowledge gaps for which evidence is required to inform policy and practice to enable stakeholders to harness the potential of ICT based innovations offered for agricultural development in SSA.

Climate policy research uptake dynamics for sustainable agricultural development in Sub-Saharan Africa

The main purpose of the paper is to espouse the policy promptings of climate change and food security-based researches that would lend appropriate solutions to avert the risks of food insecurity, due to climate variability and change in Ghana and sub-Saharan Africa (SSA). Design and methodological approach used a systematic review of preponderantly existing research findings. The paper discussed within the context of systematic discourse analysis, policy research uptake dynamics for food production and climate variability and change in SSA. The results indicated that the threats of adverse impacts of climate change are expected to be higher on Sub-Saharan Africa’s food systems, notwithstanding, little effort is given to the implementation of policy recommendation by sub-Saharan African countries’ agriculture sectors. This paper further argues broadly that there is still growing levels of policy implementation ambivalence towards the achievement of the Sustainable Development Goal 13, which enjoins nations to take immediate action to combat climate change through the institutionalization of sustainable adaptation and mitigation strategies, among many Sub-Saharan African countries. Government departments of food and agriculture, as well as meteorological agencies, require proactive inter-sectorial responses and collaboration to address the scourge of climate variability and change in Ghana and sub-Saharan Africa. The paper recommends prompt and dispassionate implementation of climate change policies, as an imperative need for sustainable food production systems, in response to changing climatic patterns in sub-Saharan Africa.

Faith in international agricultural development: Conservation Agriculture in sub-Saharan Africa

The role of faith and religion in international development cooperation is hotly debated today. The legitimacy of this role remains, however, often confided to instrumental reasons. Yet, thinking about faith and religion only in instrumental terms leaves unquestioned the possibility of a religious background of development cooperation as a practice itself and the potential role of faith through individual practitioners that operate within secular NGOs, and research and policy institutes. The aim of the present paper is therefore to consider the structural role of faith and worldview in relation to agricultural development, moving beyond the discourse of instrumentality. We do this by focusing on Giller and Andersson’s political agronomy analysis of the promotion of Conservation Agriculture in Zimbabwe by the faith-based organisation ‘Foundations for Farming’. We argue that a distinction should be made between religion as a practice of believers and faith functioning as a worldview in every practice. In addition, we argue that it is helpful to distinguish between different kinds of practices involved in agricultural development in sub-Saharan Africa, namely farming practice, agronomic scientific practice, and faith practice. The value of this philosophical analysis is that it challenges a dichotomous model of ‘science-based versus faith-based’ approaches to agricultural development. Furthermore, specific kinds of normativity are identified as always already functioning inside practices, rather than practices being neutral spaces that are (subjectively) infused with normativity by applying external ethical standards.

Corporate Social Responsibility and the Role of Rural Women in Sustainable Agricultural Development in Sub-Saharan Africa: Evidence From the Niger Delta in Nigeria

Low productivity among female farmers when compared with their male counterparts is considered an outcome of limited access to agricultural land and inputs. The objective of this investigation was to assess the impact of multinational oil companies’ (MOCs’) CSR on rural women access to modern agricultural inputs in the Niger Delta, Nigeria. A total of 700 rural female farmers were sampled across the region. Results from the use of a logit model indicated that CSR recorded significant success in agricultural development generally, but has undermined equality. This implies that if a woman’s agricultural productivity is continuously hindered by unequal access to agricultural resources (or opportunities) and widespread inequality will limit poverty reduction efforts in Nigeria. The results also showed that women depended on CSR of MOCs for policy dialogue and advocacy for women’s access to agricultural land and inputs. Supporting agricultural initiatives that focus on empowering women would boost food security in sub-Saharan Africa.

Four Agricultural Financing Scenarios for Sub-Saharan Africa toward 2055: Conditions for Governmental Policy Interventions

This article reports on a research effort that looked at the future of agricultural financing in Sub-Saharan Africa, and provides governments in the region with key insights into agricultural development and the rural agricultural financing challenges. In the process of knowledge creation, a mixed-method approach was followed, with the futures triangle, emerging issues analysis, and causal layered analysis (CLA) being used to deepen the level of understanding regarding the future of agricultural financing. In addition, a real-time Delphi study was conducted to validate and prioritize the emerging trends and driving forces, and to incorporate expert knowledge into the possible financing futures. Four scenarios are presented that aim to stimulate new thoughts on policies that can facilitate increased financial inclusion in agricultural development in Sub-Saharan Africa.

Confronting Tradeoffs Between Agricultural Ecosystem Services and Adaptation to Climate Change in Mali

Changing climatic conditions present new challenges for agricultural development in sub-Saharan Africa. Sorghum has proven to be an adaptable and resilient crop despite limited funding for crop development. Recent breeding efforts target hybrid and perennial technologies that may facilitate adaptation to climate change. Advantages of perennial crops over their annual counterparts include improved soil quality and water conservation and reduced inputs and labor requirements. In contrast, hybrid crops are often bred for improved grain yield and earlier maturation to avoid variable conditions. We use discrete choice experiments to model adoption of sorghum as a function of attributes that differ between these technologies and traditional varieties in Mali. Overall, the main perceived advantage of perennial crops is agricultural ecosystem services such as soil improvement, while adoption of hybrid crops is hampered by the inability to reuse seed. Women farmers are less concerned about higher labor requirements associated with perennial crops and the ability to reuse hybrids seeds than male farmers. Farmers prefer traditional sorghum to perennial sorghum and are indifferent between traditional and hybrid sorghum. These findings have important policy implications for understanding tradeoffs that are central to farmer decision making when it comes to breeding technologies for climate adaptation.

Measuring heterogeneity, survey engagement and response quality in preferences for organic products in Nigeria

ABSTRACTThe identification of the market potentials of organic products is important in the drive towards a sustainable agricultural development in sub-Saharan Africa (SSA). However, available evidence shows that valuing attributes of credence goods (such as organic products) while using stated preference methods faces additional obstacles compared to other normal goods. In this study, we examine consumers’ preferences and willingness-to-pay (WTP) for health and environmental attributes of organic products in Nigeria. We employ an approach that allows us to adequately capture the value of organic products by linking part of the heterogeneity across respondents to differences in scale, while making use of indicators of survey engagement, without risks of endogeneity bias and measurement error that arise from the deterministic methods. The empirical results show that market for organic products exists in Nigeria, with reduction in pesticide residues attribute attracting the highest value, followed by the certification programme. Furthermore, we observe that increases in the latent engagement variable lead to a greater probability of agreement with statements relating to survey understanding and realism, and hence more substantive output.

Animal trypanosomosis: making quality control of trypanocidal drugs possible

African animal trypanosomosis is arguably the most important animal disease impairing livestock agricultural development in sub-Saharan Africa. In addition to vector control, the use oftrypanocidal drugs is important in controlling the impact of the disease on animal health and production in most sub-Saharan countries. However, there are no internationally agreed standards (pharmacopoeia-type monographs or documented product specifications) for the quality control of these compounds. This means that it is impossible to establish independent quality control and quality assurance standards for these agents. An international alliance between the Food and Agriculture Organization of the United Nations, the International Federation for Animal Health, the Global Alliance for Livestock Veterinary Medicines, the University of Strathclyde and the International Atomic Energy Agency (with critical support from the World Organisation for Animal Health) was established to develop quality control and quality assurance standards for trypanocidal drugs, with the aim of transferring these methodologies to two control laboratories in sub-Saharan Africa that will serve as reference institutions for their respective regions. The work of the international alliance will allow development of control measures against sub-standard or counterfeit trypanocidal drugs for treatment of trypanosome infection. Monographs on diminazene aceturate (synonym: diminazene diaceturate), isometamidium chloride hydrochloride, homidium chloride and bromide salts and their relevant veterinary formulations for these agents are given in the annex to this paper. However, the authors do not recommend use of homidium bromide and chloride, because of their proven mutagenic properties in some animal test models and their suspected carcinogenic properties.

Proteomic Selection of Immunodiagnostic Antigens for Trypanosoma congolense

Animal African Trypanosomosis (AAT) presents a severe problem for agricultural development in sub-Saharan Africa. It is caused by several trypanosome species and current means of diagnosis are expensive and impractical for field use. Our aim was to discover antigens for the detection of antibodies to Trypanosoma congolense, one of the main causative agents of AAT. We took a proteomic approach to identify potential immunodiagnostic parasite protein antigens. One hundred and thirteen proteins were identified which were selectively recognized by infected cattle sera. These were assessed for likelihood of recombinant protein expression in E. coli and fifteen were successfully expressed and assessed for their immunodiagnostic potential by ELISA using pooled pre- and post-infection cattle sera. Three proteins, members of the invariant surface glycoprotein (ISG) family, performed favorably and were then assessed using individual cattle sera. One antigen, Tc38630, evaluated blind with 77 randomized cattle sera in an ELISA assay gave sensitivity and specificity performances of 87.2% and 97.4%, respectively. Cattle immunoreactivity to this antigen diminished significantly following drug-cure, a feature helpful for monitoring the efficacy of drug treatment.
