Do regional-specific differences influence smallholder farmers’ climate information use? Evidence from Ghana
(2025) Owusu, Victor; Asravor, Jacob
Mounting evidence underscores the importance of improving smallholder farmers’ use of reliable climate information (CI) in sub-Saharan Africa (SSA). Previous studies have not examined the differences in region-specific climate information use, as well as predictors of the source, type and timing of climate information use. In this study, we provide empirical evidence on how location-specific differences influence the source, type and timing of CI use. Integrating cross-sectional data from 503 households in the Upper West Region (UWR) and Brong-Ahafo Region (BAR) of Ghana into a multivariate probit model, our results indicate that farm households in the two regions exhibit different preferences regarding the source, type and timing of CI use. We find that while households in the BAR are more interested in CI ahead of the season – given that rainfall is relatively secure in that region, CI use ahead of the season is of less interest to those in the UWR where rainfall is more erratic. Our results further show that while CI source, type and timing are considerably influenced by education, distance to the farm, access to credit and extension in the UWR, gender, farm size, education and tractor access tend to drive the source, type and timing of CI use in BAR. These findings underscore the need for a more downscaled and context-specific strategy in disseminating CI services in the various regions of SSA. Practical implications: Notwithstanding evidence that the adverse impacts of the changing climate on smallholder livelihoods continue to vary within and across communities, districts, regions and agro-ecological zones (Abbam et al., 2018) in sub-Saharan Africa, little is known about how location-specific distinctions in climate change impact, infrastructural endowments as well as socioeconomic and plot-level attributes of smallholder farmers influence farm households’ use of climate information (CI). Given that these location-specific distinctions can considerably influence the generation and dissemination of CI, and its subsequent uptake by farm households in various regions, the empirical findings from this study are relevant for policy formulation towards boosting the use of CI. Evidence from this study strongly suggests that the diverse locations of smallholder farmers tend to significantly influence the source, type and period of CI use; for example, farm households in the Brong-Ahafo Region, a relatively more infrastructurally developed region, have better prospects of accessing different types of CI from diverse sources. We further find that the period of the cropping season in which CI is used is considerably influenced by the location of the farmers; and we identify disparities in the plot-level, institutional and socioeconomic characteristics of rural households in these two study regions that significantly influence the types, sources and times of CI used by farm households. Consequently, there is a need to take into account the unique regional, agro-ecological, plot-level, institutional and socioeconomic attributes of farm households. Policy recommendations on CI use should be tailored to the needs of these specific locations rather than being wholesale. Investment in rural infrastructure may trigger economic opportunities in deprived regions such as the Upper West Region. This may motivate rural households in such regions to invest in different CI types and sources for enhanced uptake of climate information.
Farming forest enclosures
contestations, practices and implications for tackling deforestation in Ghana
(2022) Kumeh, Eric Mensah; Birner, Regina
Scientists and policymakers are waking to the menacing impacts of deforestation on biodiversity and the livelihoods of the over one billion people reliant on forests. Concurrently, an upward trend in population and its corresponding rise in the global demand for feed, food, fuel, and fibre exerts new demands on limited land resources available to multiple stakeholders. As the competition over land intensifies, many farmers in the tropics employ several strategies to cultivate areas designated as forest reserves for their livelihoods, leading to further deforestation and conflicts with state forestry agencies. Moreover, despite decades of investments in institutions to directly fund smallholder farmers’ participation in rehabilitating deforested landscapes, little is known about the reach and performance of existing financial incentive mechanisms. This dissertation adds to filling these knowledge gaps based on qualitative case studies embedded in multiple analytical and data collection approaches in Ghana, which loses near 2% (135,000 ha) of its forests annually despite several efforts to overcome the challenge. Following a brief introduction and clarification of conceptual underpinning in Chapter 1, the knowledge gaps are addressed with three empirical publications (chapters 2-4). Chapter two examines why and how farmers in forest communities gain and secure access to their farmlands within forest reserves to produce food and cash crops against state law. Through process-net maps, focus group discussions, interviews, and field observation, data were gathered through an extended field stay in Ghana’s Juabeso district. The findings unbridle the multiple structural and relational mechanisms farmers apply to evade state attempts to rein in illegal farming in the area and how institutional deficiencies, notably corruption and elite capture of farming benefits by native chiefs, reinforce farming in forest reserves. The chapter discusses the broader implications of the findings for the Ghanaian government’s attempts to accelerate forest landscape rehabilitation, noting that such efforts will need to adapt to the multiple struggles and latent actor interests to succeed. Chapter three disentangles the narratives and experiences of forest communities and compares them with the current assumptions underlying forest policy in Ghana from the perspective of the most dominant forest policy actors. The results contend with current assumptions that portray forest communities as environmentally destructive. Alternatively, it reveals that while several factors combine to drive forest-dependent communities to cultivate forest reserves, the challenge of food insecurity is paramount but unconveyed to the forest policy arena. The chapter proposes a novel concept of food security corridors (FSCs) as a meta-narrative for harmonising competing actor interests in forest reserves. The chapter also discusses the feasibility of FSCs and calls for further efforts to refine and pilot the concept in the global search for solutions to forest and agriculture land-use conflicts in the tropics. Chapter four examines the governance of Ghana’s Forest Plantation Development Fund as an incentive system instituted to attract smallholders into landscape rehabilitation based on interviews with tree growers, forestry officials and NGO staff. The study revealed that the legal provisions instituted to ensure the fund’s transparent operation were not implemented by fund administrators. Many stakeholders were clueless about the Fund and could neither access nor demand accountability in its administration. The chapter clarifies the information needs of various fund stakeholders, such as eligibility criteria, funding cycles, annual inflows and outflows, and a list of beneficiaries. It also discusses the implications of the findings, including mechanisms required to trigger the transparent running of the fund by its administrators. The thesis reveals new patterns of perennial land competition between state and traditional institutions. It demonstrates how prevailing institutional challenges reinforce this competition and enable unsustainable land use to flourish. At the same, it points to lapses in governance, including state failure to evolve its forest policies to meet changing demands and needs among contemporary actors and how the same challenges curtail access and ability to support forestation rehabilitation efforts in Ghana. Overall, the thesis notes that while tackling farming in forest reserves can be challenging due to its multiple drivers and the competing actor interests, FSCs have the potential to serve as an entry point that enables government and other actors to resolve their differences and find lasting solutions that enable local communities to achieve their livelihoods needs while contributing to sustainable land use. However, for this potential to be realised, actors need to invest in refining and piloting FSCs in specific localities.
Governance of emerging biomass-based value webs in Africa
case studies from Ghana
(2018) Poku, Adu-Gyamfi; Birner, Regina
Rising global demand for food as well as for feed and biomass-based raw materials such as fuel and fibre crops has increased pressure on the agricultural sector, especially in Sub-Saharan Africa. The expected trend of increased demand for more diverse biomass-based produce from agricultural land effectively transforms the agriculture sector from just a food-supplying to a biomass-supplying sector in the growing international bioeconomy. This transition is leading to the development of biomass-based value webs whereby there are complex systems of interlinked value chains in which food, fodder, fuels, and other raw materials are produced, processed, traded and consumed. Against this background, this thesis aims to evaluate the appropriate roles of the public, private and third (civil society) sectors in facilitating the transformation of the agricultural sector in the developing bioeconomy in Ghana. The study focuses on the emerging value webs of cassava (Manihot esculenta) and maize (Zea mays), which are the two most important staple crops in Ghana.
Small-scale irrigation and womens empowerment
lessons from an irrigation intervention in Northern Ghana
(2022) Basauri Bryan, Elizabeth; Zeller, Manfred
This dissertation uses a mixed-methods approach to explore issues related to women’s empowerment and small-scale irrigation from several different angles: conceptually, based on a literature review, qualitatively and quantitatively, based on a case study in Northern Ghana, and qualitatively, as part of a larger effort of development organizations to promote adaptation to climate change. The analysis relies on a conceptual framework that illustrates the linkages between small-scale irrigation and the domains of women’s empowerment as well as the broader opportunity structure shaping these relationships. It then uses qualitative and quantitative data from the case study area to identify what aspects of women’s empowerment are salient in this context and how the irrigation intervention influences outcomes for women. Finally, the dissertation draws lessons from a capacity needs assessment of development organizations to identify areas for strengthening the delivery of gender-sensitive programs. Thus, the main research questions addressed by this dissertation are: 1) What are the linkages between small-scale irrigation technologies/systems and dimensions of women’s empowerment? 2) What aspects of women’s empowerment emerge as the most salient in the context of Northern Ghana where small scale irrigation is practiced and modern technologies (motor pumps) are being introduced? 3) How does the introduction of small-scale irrigation technologies (specifically motor pumps) affect indicators of women’s empowerment? 4) What are the gender-related capacity needs of development organizations working to promote climate change adaptation (of which small-scale irrigation is an important practice)? The findings in this dissertation suggest that there are many factors to consider in the design and dissemination of small-scale irrigation technologies to ensure that these are equitably distributed and that both men and women have the opportunity to engage in and benefit from irrigation. These include gendered preferences for the type of irrigation technology or system, the underlying socio-political environment shaping the barriers that men and women face, and implementation approaches. Moving beyond simply reaching women (that is, counting their participation in program activities) to benefitting and empowering women (increasing their well-being outcomes and expanding their ability to make strategic life decisions) requires knowledge of the local context and dedicated attention toward ensuring that outcomes for women are achieved, even if this means expanding activities and opportunities outside of agriculture. Thus, greater efforts are also needed to build the capacity of implementing organizations to deliver gender-responsive programs. Creating platforms, like stakeholder consultation processes or dialogues, for setting goals and sharing information, approaches, and lessons learned is one way to build this capacity. Integrating gender-sensitive research tools into strategy development, project design, implementation, and monitoring and evaluation of implementing agencies would also support the development of more gender-responsive irrigation interventions and would contribute to fill remaining research gaps on the gendered implications of alternative agricultural technologies and practices. While this dissertation provides some evidence on the impacts of motor pumps for small-scale irrigation on women’s empowerment, this is only one of many types of irrigation technologies and approaches. More research is needed on the implications for women’s empowerment of alternative irrigation technologies, systems, and dissemination tactics, including group-based and service-based approaches.
Technology adoption and farm performance in sub-Saharan Africa: evidence from Mozambique and Ghana
(2025) Asravor, Jacob; Zeller, Manfred
Increasing the productivity of agriculture in sub-Saharan Africa (SSA) is fundamental to achieving many of the Sustainable Development Goals (SDGs) in the region and, by extension, in the world. Given its importance to rural livelihoods and national economies in SSA, productivity growth in this crucial sector has the potential to stimulate broad-based poverty reduction (SGD 1) and further address the persistent food insecurity and malnutrition challenges (SDG 2) faced by the region. However, despite its potential for growth and importance to the region, productivity growth in agriculture has either stagnated or declined in SSA over the years. Efforts to tackle this persistent challenge have been focused on the promotion of improved technological packages and modern farming practices in various parts of the region. Nonetheless, adoption has mostly remained sluggish across SSA, stressing the continuing need for a deeper understanding of the underlying barriers to sustained adoption, as well as the effects of adopted technologies and farming practices on farm performance, particularly in terms of technical efficiency and technological gains. The smallholder farming contexts of Mozambique and Ghana offer distinct cases for gaining useful insights into the underlying barriers to sustained adoption of modern technologies and farming practices, as well as their effects on farm performance. Specifically, despite ongoing efforts by the Mozambican government and development partners to promote sustainable intensification practices, such as integrated soil fertility management (ISFM) practices (including mineral fertilizer, improved seeds and depending on the location, organic inputs such as manure and compost), adoption remains low among farm households. As a result, resource-poor farmers often resort to unsustainable land use practices, such as shifting cultivation, slash-and-burn agriculture, deforestation and forest degradation, along with low-cost agronomic practices like crop rotation, crop residue retention and intercropping to safeguard soil fertility. However, evidence is scarcely available on the underlying barriers to sustained adoption of promoted ISFM practices, along with the technological and technical efficiency gains associated with integrating improved versus recycled seeds with agronomic practices in Mozambique. Furthermore, one of the key challenges to technology adoption, as well as to farm performance and the long-term sustainability of agriculture, is the issue of aging farming population. This issue is particularly pressing in Ghana, where, in addition to the growing disinterest of young people in farming and an estimated life expectancy ranging from 55 – 65 years, the average age of farmers is reported to be 55. Given that the majority (73.5%) of Ghana’s population is below the age of 36, an improved understanding of how farm operators’ age influences their managerial performance and technology adoption is crucial for shaping evidence-informed policies aimed at attracting, retaining and leveraging this demographic dividend within the Ghanaian agricultural sector. From the foregoing, this thesis has three key objectives: (1) to explore context-specific evidence on the systemic barriers to sustained adoption of integrated soil fertility management (ISFM) practices by Mozambican smallholder farmers; (2) to examine the technological and technical efficiency gains associated with integrating improved versus recycled seeds with agronomic practices such as crop rotation, intercropping and crop residue management by Mozambican smallholder farmers; and (3) to assess how the age of farm operators – disaggregated into the youth, middle-aged and aged – influences their managerial performance and farm technology adoption in Ghana. The objectives of this thesis were achieved using data from both primary and secondary sources. Relying on mixed-methods research design, qualitative data were drawn using key informant interviews (KIIs) and focus group discussions (FGDs), and quantitative data via a household survey in the Central and Northern zones of Mozambique. These primary data were used to address the first and second objectives of the thesis. Overall, 32 qualitative interviews, consisting of 8 FGDs, 5 medium- and large-scale farmer KIIs and 19 expert KIIs were conducted in Mozambique. This was followed by a household survey which was conducted in the Central and Northern zones of Mozambique, involving 607 farming households who were selected through a multi-stage sampling technique. Both datasets were collected in 2022. To address the third objective of the thesis, secondary data from two nationally representative surveys in Ghana were used. These include all seven waves of the Ghana Living Standards Survey (GLSS) which were conducted from 1987/88 – 2016/17 and the two waves of the Ghana Socio-economic Panel Survey (GSPS) conducted between 2009/10 and 2014/15. While the GLSS was implemented using a repeated cross-sectional design, the GSPS followed a panel design. Overall, 24,596 farm households across Ghana were included in the sample for analysis. This thesis is organized into five chapters. Chapter 1 introduces the research topic by providing a general overview of the study within the global and sub-Saharan African contexts, followed by background information on agriculture and technology adoption in both Mozambique and Ghana. Chapter 2 explores the systemic barriers that continue to impede the sustained uptake of ISFM practices among Mozambican smallholder farmers. Chapter 3 evaluates the technological and technical efficiency gains associated with existing farmer practices of integrating improved versus recycled seeds with agronomic practices in Mozambique. Chapter 4 examines the relationship between farm operators’ age, technology adoption and managerial performance in Ghana. Finally, chapter 5 presents the conclusion of the thesis, outlines its limitations and makes recommendations for policy and future studies. Chapter 2 relies on mixed-methods research design to explore the systemic barriers to sustained adoption of ISFM practices among Mozambican resource-poor farmers. Complementing content analysis of qualitative data with descriptive analysis of data from a household survey, the findings indicate that whereas Mozambican smallholder farmers have generally recognized the compelling need for ISFM practices in high-value crop production systems such as vegetables, cotton, sugarcane and tobacco, they are reluctant to make similar investments in food crops. Instead, they adopt low-cost agronomic practices such as crop residue management, intercropping, crop rotation and shifting cultivation to safeguard soil fertility in food crop systems. Evidence further shows that the use of improved seeds, mineral fertilizers and depending on the location, external organic inputs such as manure and compost, is more prevalent among three groups of Mozambican smallholder farmers: independent vegetable producers, farmers participating in contract farming schemes and those residing in districts bordering Malawi, Zambia and Zimbabwe. Additionally, despite expressing strong willingness to invest in these inputs, farmers’ access to and use of these inputs are hindered by a complex set of systemic barriers, including unfavorable market conditions which limit profitability and intensify risk; institutional limitations such as credit constraints and human capital limitations; liquidity constraints; challenges associated with key ISFM components; an existing culture of dependency shaped by past experiences of farmers with free inputs; and entrenched perceptions among both farmers and professionals that Mozambican soils are inherently “fertile” or “virgins” and “fertilizers destroy the soil”. Given these findings, the study recommends that interventions aiming to promote sustainable land use practices like ISFM in land-abundant contexts of SSA like Mozambique, should prioritize addressing these systemic barriers to ensure sustained adoption of these practices. For instance, to raise productivity in food crop systems, agrarian interventions should adopt a holistic value chain approach which goes beyond the production phase to strengthen other critical segments of the value chain, such as extending agro-dealer networks to major production areas, as well as enhancing access of smallholder farmers to output markets that offer stable and fair prices. Again, there is the urgent need to intensify education and raise awareness among both farmers and professionals to dispel the widespread misconception that fertilizers damage the soil and on the need for farmers to implement ISFM as a package rather than in isolation. Addressing these systemic constraints holds an enormous prospect for fostering the sustained uptake of sustainable intensification practices like ISFM in Mozambique. Drawing on the findings from chapter 2, which indicates that Mozambican smallholder farmers seldom invest in purchased inputs for food crops, chapter 3 utilizes the same data to assess the technological and technical efficiency gains associated with existing farmer practices of integrating improved versus recycled seeds with agronomic practices, including crop rotation, intercropping and crop residue management in food crop systems. Relying on an endogeneity-corrected stochastic frontier and metafrontier functions to analyze the quantitative data, results from this first-stage analysis were contextualized and reinforced with evidence from the qualitative data. The findings suggest that farm households who integrated improved seeds with agronomic practices achieve a modest technological advantage (4%) relative to their peers who integrated recycled seeds with these same practices. Nonetheless, the results reveal no significant difference in technical efficiency between both groups. Instead, farm households in both groups performed these agronomic practices so poorly, such that each group could expand its total farm production by more than 50% simply by implementing these existing agronomic practices more efficiently. Consequently, the greatest potential for raising farm output in food crop systems in Mozambique lies in the capacity of resource-poor households to effectively implement these existing agronomic practices. Based on the findings, it is recommended that programs aiming to boost productivity in food crop systems in Mozambique should prioritize building the capacity of farm households to enable them implement these agronomic practices more efficiently. Encouraging resource-poor farmers to strictly adhere to recommended agronomic protocols, such as selecting the right crop mixes for intercropping and rotation, retaining crop residues on the field and using inoculants to boost nitrogen fixation in legumes can considerably enhance soil fertility and support productivity in subsequent crops. Given the increasingly aging farming population in Ghana and the urgent need for evidence-informed policies aimed at attracting and retaining the country’s growing youth population in agriculture, chapter 4 of the thesis relies on a nationally representative data from the GLSS and GSPS to evaluate how the age of resource-poor farmers influence their farm-level decision-making in terms of technology adoption and managerial performance. Drawing on a three-decade dataset from cereal-producing households and guided by the definitions of youth provided by the African Youth Charter and Ghana’s National Youth Policy, farm households were categorized into three age-based groups: youth (15–35 years), middle-aged (36–59 years) and aged (60 years and above). The findings indicate that farm operator age does not have a statistically significant effect on the type or level of agricultural technology adopted by farming households in Ghana. This finding remains robust even when the analysis is disaggregated by cereal type (i.e., maize, rice, millet and sorghum). However, the findings reveal marked differences in managerial performance between younger and older farmers, with the youth exhibiting greater managerial proficiency relative to their older peers. These findings suggest that when offered equal access to productive resources, younger farmers are better equipped to drive agricultural productivity growth in Ghana, thereby significantly contributing to the sector’s growth in the country. The study recommends for policymakers to pursue youth-focused agrarian initiatives that ensure easy access of the youth to productive resources such as land, credit and improved technologies, aimed at enabling younger farmers to leverage their potential in driving agricultural productivity gains. Overall, the findings of this thesis bring to the fore the existing systemic barriers that continue to obstruct smallholder investment decisions in sustainable land use practices like ISFM in land-abundant contexts like Mozambique and further underscore the urgent need for policy measures aimed at addressing them. It further stresses that the greatest potential for sustainably raising farm performance in low-input food crop systems in Mozambique lies in the ability of resource-poor farmers to implement these low-cost agronomic practices more efficiently. Finally, the findings highlight the need to focus on enhancing the managerial skillsets of farm operators across all age groups, especially the younger ones, rather than just concentrating on technological advancements.
The role of institutions and networks in developing the bioeconomy
case studies from Ghana and Brazil
(2019) Scheiterle, Lilli; Birner, Regina
An increasing number of countries have begun putting focus on developing a bioeconomy strategy. The bioeconomy provides a new concept with the aim to design a sustainable economy, which is knowledge-based and based on the use of biological resources. This entails on the one hand higher production of biomass and on the other tighter networks of traditional, national and international institutions. Institutional networks are pivotal for the sustainable production and use of biological resources, as well for the development of innovative biological processes and principles to exploit the potential of biomass. This thesis explores three pivotal aspects needed to take advantage of the considerable untapped potential of the bioeconomy. The first case study aims to identify the determinants of the persisting low maize yields in northern Ghana, despite the introduction of a fertilizer subsidy program. The policy is largely regarded as an instrument to increase crop productivity and contribute to food security. The second empirical study explores the role of female-led market institutions in Ghana. Marketing is central to the development of the bioeconomy and as such, trader organizations have a key role to play the value chain. The third case study investigates, taking sugarcane as a case study example, how well Brazil, the world’s leader in sugarcane production, is positioned to realize the shift from a fossil-based to a bio-based economy (bioeconomy). The two case study countries Ghana and Brazil were chosen because of their comparable net primary productivity and pedo-climatic conditions, and because of their different stages in the realization of the bioeconomy. Two components are pivotal to the success of the bioeconomy: biomass and knowledge. Based on two case studies in Ghana, this thesis investigates first the efforts to increase maize productivity in the Guinea savanna and secondly explores the role of collective action groups as central actors to address the sustainability dimension of the bioeconomy. Brazil has successfully implemented pivotal aspects of the bioeconomy, especially in the sugarcane sector. For this reason it lends itself well to analyze the role of institutions and networks in the development of new processes and products. This study adopts a mixed methods approach to address three key aspects of the development of the bioeconomy: production, marketing, and the overall innovation system. Data collection and analysis included qualitative and quantitative methods from various disciplines. The findings are presented in three papers, which this cumulative thesis is composed of. The first paper adopts a multidisciplinary approach. A household survey, in-depth interviews, and focus group discussions served to gather data on the socio-economic challenges of maize production in the Guinea savanna. Additionally, soil and fertilizer samples were analyzed to identify natural constraints and potential governance challenges. The results from this paper show that both socio-economic and biophysical parameters contribute to an improved understanding of site-specific challenges, resulting in low maize productivity in the Guinea savanna of Ghana. The second paper explores the role of female-led market associations across regions, ethnicities, and market typologies throughout Ghana. For this study a qualitative approach was chosen with participant observation and in-depth open-ended interviews conducted with traders, both in and out of leadership positions. The results could not empirically confirm the prevailing discourse on the monopolizing power of female-led market associations. The study rather finds that traders’ collective action provides vital safety-net measures for asset-poor women engaging in risky market activity. However, the public perception is challenging female trader agencies. The third paper analyzes the role of institutions and focuses on the innovation networks in the sugarcane sector in Brazil. The study combines the novel concept of ‘biomass value-webs’ with the established National Innovation System concept. For data collection, in-depth interviews and Net-Maps as a participatory tool were applied. The results illustrate the importance of innovation networks for Brazil to become a front-runner in the future bioeconomy. In particular, it emphasizes the importance of integrating national and international private sector organizations, and the need for incentives to foster collaboration with knowledge institutions. Based on these findings, one can conclude that strengthening the efforts to tailor site-specific solutions that consider the inter-disciplinary nature of crop production, marketing and development of processes is crucial to the bioeconomy. Overall, more attention to innovation networks is required to master the challenges of the bioeconomy and take full advantage of its opportunities.
