How accurate are existing land cover maps for agriculture in Sub-Saharan Africa?

Satellite Earth observations (EO) can provide affordable and timely information for assessing crop conditions and food production. Such monitoring systems are essential in Africa, where food insecurity is high and agricultural statistics are sparse. EO-based monitoring systems require accurate cropland maps to provide information about croplands, but there is a lack of data to determine which of the many available land cover maps most accurately identify cropland in African countries. This study provides a quantitative evaluation and intercomparison of 11 publicly available land cover maps to assess their suitability for cropland classification and EO-based agriculture monitoring in Africa using statistically rigorous reference datasets from 8 countries. We hope the results of this study will help users determine the most suitable map for their needs and encourage future work to focus on resolving inconsistencies between maps and improving accuracy in low-accuracy regions.

Effect of ethyl methane sulphonate on growth, yield and some physiological parameters of Bambara groundnut (Vigna subterranea (L.) verdc) in non - water stressed and water stressed conditions

Bambara groundnut (Vigna subterranea (L.) Verdc.) is a legume cultivatd majorly for it’s seeds and commonly grown by subsistence farmers in sub-Saharan Africa. In order to determine the effect of ethyl methane sulphonate (EMS) mutagen on the growth, yield and some physiological parameters of non-water stressed (NWS) and water stressed (WS) bambara groundnut. It’s seeds were treated with five concentrations (0.00 (control), 0.25, 0.50, 0.75 and 1.00% v/v) Ethyl methane sulphonate and were grown under two conditions: non-water stressed and water stressed. Analysis of variance (ANOVA) revealed significant differences (P ≤ 0.50) in the emergence percentage (6 DAS), germination percentage (7 DAS), plant height (PH), number of leaves per plant (NL), leaf length (LL), leaf width, (LW), relative water content (RWC), chlorophyll a, b and total chlorophyll contents in the non-water stressed and water stressed plants. After rewatering at 8 WAS, highest number of leaves in NWS and WS conditions were observed in 0.75% EMS concentration (229, 189), highest leaf length in NWS and WS plants were observed in 0.50% EMS concentration (9.47cm, 9.13cm). Highest leaf width in NWS and WS plants was observed in 0.25% EMS concentration (4cm, 3.63cm). Highest number of pods per plant (NP) and weight of pods per plant (WP) were observed in 0.75% EMS concentration only in NWS plants. Highest chlorophyll a, b and total chlorophyll content was observed in 1.00% EMS concentration. The result form this study showed that Ethyl methane sulphonate (EMS) mutagen concentration increased the growth, yield and physiological parameters of Bambara groundnut in non-water stressed condition at different doses, however there was no positive effect of EMS on yield in the water stressed plants.

Characterization of urban agriculture and farmers’ climate change adaptation: the case of Urban Wa, Ghana

Urban agriculture in sub-Saharan Africa has the potential to significantly improve urban food security and feed the underprivileged when promoted. In Ghana, urban agriculture has several characteristics that distinguish it from traditional farming practices. However, climate change poses a significant threat to urban agriculture, as changing weather patterns can lead to droughts, floods, and extreme weather events that damage crops and animals. This study explored the characteristics of urban food crops and livestock production in the Wa township, Ghana. Mixed methods of data collection and analysis were employed. A sample of 362 urban households was administered survey questionnaires supplemented with 12 key informant interviews. Descriptive and content analysis were carried out, with the results presented in tables, graphs, and narratives. The study found that amidst climatic stressors, urban agriculture is characterized by the production of animals such as chickens, sheep, and goats and crops like maize, yam, beans, cabbage, and pumpkin. Land is acquired through purchasing, though other farmers obtain land from relatives and friends. There is a very strong relationship between residential class and the type of urban farming (Cramer’s V = 0.291 > 0.25) and a moderate relationship between residential class and land acquisition type (Cramer’s V = 0.108 > 0.10). The study concludes that urban farming is characterized by mixed farming coupled with crop diversification, which has implications for climate change adaptation measures. To adapt urban agriculture to climatic stressors, the study recommends that the Ministry of Food and Agriculture (MoFA) should streamline agricultural policy interventions in urban agriculture to promote agriculture intensification.

Impact of climate-smart agricultural practices on smallholder farmers' resilience in Ethiopia

Climate change poses challenges to smallholder farmers in sub-Saharan Africa, including Ethiopia. To address this, adopting Climate-Smart Agricultural Practices (CSAPs) is crucial for building resilient communities. However, limited evidence exists on the impact of CSAPs on farmers' resilience. Therefore, this study aimed to examine the impact of Climate-Smart Agricultural Practices (CSAPs) on the resilience of smallholder farmers and identify the factors determining their resilience. The study collected both quantitative and qualitative data. Quantitative data was obtained from 646 survey households using household surveys, while qualitative data was gathered through focus group discussions and key informant interviews. Findings reveal that there is an agroecological difference in resilience status and factors like the education level of the household head, livestock size, and agricultural extension worker visits positively influence the resilience of CSAP-adopting smallholder farmers. Conversely, sharing crop outlands negatively impacts the adoption of climate-smart practices. Crop CSAP adopters show significantly higher resilience gains (37.74% ATT) compared to non-adopters. Non-adopters could have experienced a substantial improvement (23.83% ATU) if they had adopted CSAPs. Positive and significant effects on resilience were also observed for livestock and soil management CSAP adopters, with an improvement of 28.36% and 40.58%, in resilience capacity, respectively. Non-adopters of these CSAPs could have enhanced their resilience by 24.74% and 10.80%, respectively, if they had adopted these practices. This underscores the need to adopt more CSAPs and the importance of considering these factors in designing policies and promoting CSAP to enhance the resilience of smallholder farmers in Ethiopia and similar contexts.

Evaluation of land suitability for surface irrigation under changing climate in a tropical setting of Uganda, East Africa

CONTEXTAssessment of land suitability for irrigation under changing climate holds paramount significance given the pronounced reliance on rainfed agriculture in sub-Saharan Africa. OBJECTIVETo investigate land suitability for surface irrigation under changing climate in a tropical setting of Uganda, East Africa and explore implications for irrigation development as well as food security. METHODSThe study used a GIS-based multi-criteria evaluation using the Analytical Hierarchy Process that considered seven factors: soil texture, slope, land use/land cover, soil drainage, distance to river, distance to road network and rainfall deficit. Each factor was rasterized, reclassified and standardized to a similar measuring scale, resulting in a numeric range; higher values indicating areas that are more suitable and lower values indicating areas that are less suitable for irrigation. Weighted factors were added using the weighted overlay approach in the ArcGIS environment to create the final irrigation suitability map. Suitability was further assessed under two scenarios; an increase in average temperature of 1.5 °C and 10% increase in annual rainfall for the period from 2041 to 2060 (scenario I) and an increase in average temperature of 4.3 °C and 20% increase in annual rainfall for the period from 2061 to 2080 (scenario II). RESULTS AND CONCLUSIONSFindings reveal that of the entire area of Uganda, 43.7% is currently constrained, 32.4% is moderately suitable, 23.1% is marginally suitable, only 0.9% is highly suitable, and only 0.02% is not suitable for surface irrigation. Highly suitable land is mostly found in the Lake Victoria Crescent whereas land not suitable for surface irrigation is mostly found in the Karamoja zone. Suitability of land for surface irrigation generally decreased with changing climate. Land not suitable for surface irrigation increased to 0.11% and 0.34%, and marginally suitable land increased to 28.4% and 35.8% of the total area, under scenarios I and II respectively. Whereas moderately suitable land decreased to 27.5% and 20.1%, and highly suitable land decreased to 0.29% and 0.046% of the total area, under scenarios I and II respectively. In both scenarios, suitable land for surface irrigation is highest in the South East L. Kyoga Flood Plain and lowest in the Western Mid-Altitude Farmland. The investigation underscores the dynamic nature of irrigation suitability of land, subject to various influencing factors with climate dynamics being a major factor. SIGNIFICANCEThe findings emphasize the importance of adopting adaptive strategies and incorporating climate change considerations into irrigation decision-making processes for increased food production.

Aspirations, ambitions and the adoption of diverse fruit trees – a case study of the livelihood effects in Kenya

Current food production systems all over the world face numerous challenges. Particularly smallholder farming in sub-Saharan Africa is in substantial need of sustainable solutions. Yet, the adoption of already existing sustainable agricultural practices such as agroforestry often remains low. This paper aims to deepen the understanding of smallholders’ decision-making processes for agroforestry adoption. Using the example of a CIFOR-ICRAF agroforestry project (Fruit Tree Portfolios), we examine the associated influences of ambition and livelihood aspirations on adoption and assess the impact of agroforestry on household well-being. We conduct several statistical analyses, including a logistic regression on the influence of ambitions and aspirations on adoption, and a linear regression with endogenous treatment effects and propensity score matching to assess the impact of adoption on well-being. The analyses are based on a primary data set collected from rural Kenyan households that participated in the project in 2021.We confirm the inverted U-shaped relationship between ambition and the willingness to take proactive steps, in this case the adoption of agroforestry, and emphasize its relevance for decision-making processes. In addition, livelihood aspirations towards off- or on-farm activities promoted the likelihood of adoption. Due to the versatility of integrating fruit trees into farms, they can serve both market- and food security-oriented purposes and thus supporting livelihoods in multiple ways. This is confirmed by the positive results of adoption on household well-being in terms of food security and household income. In summary, the inclusion of cognitive factors such as ambition and livelihood aspirations can help explain the adoption decisions of smallholder households and support inclusive and customized project designs. In the long term, these findings could have the potential to ensure that development interventions are adopted more successfully.

The soil microbiome modulates the sorghum root metabolome and cellular traits with a concomitant reduction of Striga infection

Sorghum bicolor is among the most important cereals globally and a staple crop for smallholder farmers in sub-Saharan Africa. Approximately 20% of sorghum yield is lost annually in Africa due to infestation with the root parasitic weed Striga hermonthica. Existing Striga management strategies are not singularly effective and integrated approaches are needed. Here, we demonstrate the functional potential of the soil microbiome to suppress Striga infection in sorghum. We associate this suppression with microbiome-mediated induction of root endodermal suberization and aerenchyma formation and with depletion of haustorium-inducing factors, compounds required for the initial stages of Striga infection. We further identify specific bacterial taxa that trigger the observed Striga-suppressive traits. Collectively, our study describes the importance of the soil microbiome in the early stages of root infection by Striga and pinpoints mechanisms of Striga suppression. These findings open avenues to broaden the effectiveness of integrated Striga management practices.

Efficacy of neem oil, <i>Zanthoxylum zanthoxyloides</i> and <i>Vernomia colorata</i> extracts on ticks and multi-resistant bacteria isolated from milk in the dairy value chain in Northern Côte d’Ivoire

Livestock diseases are a major constraint to farmers in sub-Saharan Africa. However, an inadequate use of acaracides and antibiotics for  animal diseases control leads to multi-resistance. Research on medicinal plants can be an alternative. The aim of this study was to assess  the efficacy of three plant extracts on cattle ticks and multi-resistant bacteria isolated in milk from the Korhogo dairy basin. A cross- sectional survey was conducted from March to August 2023 in 24 farms in northern Côte d’Ivoire. Rhipicephalus (Boophilus) microplus  and Amblyomma variegatum female adult ticks were sampled. A questionnaire was administrated to farmers on their knowledge and  practices on diseases control. Three plant extracts (Azadirachta indica, Vernomia colorata and Zanthoxylum zanthoxyloides) were  screened for bio-acaricide and anti-bacterial activities using adult immersion test and disc-diffusion assay respectively. At 5000 parts per  million (ppm), neem oil and hydroalcoholic extract of the stem bark of Z. zanthoxyloides were effective on A. variegatum while only neem  oil at 5000 ppm was active on R. (B) microplus. The three plant extracts at 5000 ppm showed no antibacterial activity on multiresistant  isolates of Escherichia coli and Staphylococcus aureus. Neem oil can be used for plant-based bioacaricide development to control the  resistant cattle tick R. (B) microplus in Côte d’Ivoire. 

Over-reliance on water infrastructure can hinder climate resilience in pastoral drylands

Extreme droughts are affecting millions of livestock farmers in sub-Saharan Africa, causing water shortages, famines, migration and fatalities. The construction of new small water infrastructures (SWIs), such as deep wells and boreholes, is increasingly supported by climate resilience programmes of non-governmental organizations and national governments to improve water availability for agro-pastoralists, especially as an emergency response to extreme droughts. Although the short-term benefits of SWI are clear, their potential cumulative impact and their long-term effects on the resilience of dryland communities remain unclear. Here, building on in-depth anthropological literature from five key African drylands, we model post-drought pastoralists’ dynamics related to SWI. We show that while developing new SWI releases water shortages in the short term, it can erode traditional adaptation practices without adequate governance. We further illustrate how our model captures early quantitative signals of resilience loss in dryland Angola. This indicates that poorly governed water development in African drylands can be a limiting factor for the long-term resilience of pastoral communities facing a range of social, demographic, economic and climate challenges.

Identification of yam mosaic virus as the main cause of yam mosaic diseases in Ethiopia

Yam (Dioscorea spp.) is a staple food crop with cultural, nutritional and economic significance for millions of small-scale farmers in sub-Saharan Africa. While various virus-like symptoms such as mosaic and chlorosis are frequently observed in yam fields in Ethiopia, little information is available on the prevalence, distribution, and molecular characteristics of viruses causing these symptoms. The aim of this study was to investigate the incidence and distribution of yam viruses and determine the primary cause of yam mosaic diseases (YMD) in Ethiopia. Both symptomatic (n = 280) and asymptomatic (n = 110) yam leaf samples were collected and tested for potyviruses using ACP‐ELISA. In addition, the symptomatic leaf samples were screened for yam mosaic virus (YMV), yam mild mosaic virus (YMMV), and cucumber mosaic virus (CMV) by DAS-ELISA. Subsequently, total RNA was extracted from 130 leaf samples comprising 94 symptomatic and 36 asymptomatic samples representing the different study areas. The representative RT-PCR amplicons (n = 6) were Sanger sequenced. The ACP-ELISA and DAS-ELISA results showed 9.2%, and 12.9% YMV infection, respectively, while the RT-PCR analysis showed 28.5% YMV positivity rate. Both CMV and YMMV were not detected in any of the samples tested. Thus, YMV is confirmed as the primary cause of YMD in Ethiopia. YMV isolates from Ethiopia shared 92–93% nucleotide identity among themselves and 85–99% with other YMV isolates from the GenBank. Phylogenetic analysis revealed that YMV isolates from Ethiopia, South America, and west-central Africa have the most recent common ancestor, while isolates from China and Japan are clustered as sister groups. This study enhances our understanding of YMV's genetic diversity and provides valuable information regarding the first report of YMV in Ethiopia.

Climate change awareness and adaptation strategies by smallholder farmers in semi-arid areas of Zimbabwe

ABSTRACT Agricultural production, food, nutrition and income security of smallholder farmers in sub-Saharan Africa are threatened by extreme weather events, such as increased frequency of mid-season dry spells and increased temperatures. Their impacts are exacerbated by the prevalence of sandy soils, characterized by limited water and nutrient retention capacity leading to low crop productivity. In this study, we aimed at assessing farmers' awareness of extreme weather events, identify adaptation strategies and evaluate maize yield from different soil fertility and water management practices. A household survey including 245 smallholder farmers in Marange, Zimbabwe was carried out. The results revealed that farmers were aware of and had experienced extreme weather events. Among adaptation strategies used were soil water-harvesting, use of improved varieties, mulching and planting trees. Maize yield remains significantly low, averaging 0.62 t ha−1 among farmers using some forms of soil fertility and water management strategies. To further understand the reason for low maize yields and improve climate change related adaptation strategies, more research is needed to quantify and confirm management practices applied by farmers, such as fertilizer use and rates, water and nutrient management, use of improved varieties as well as socio-economic factors.

Forecasting the population development of within-season insect crop pests in sub-Saharan Africa: the Pest Risk Information Service

Abstract Smallholder farmers are the mainstay of the agricultural economies of sub-Saharan Africa (SSA), where they produce several crops, predominantly centered on maize. Smallholder productivity remains limited resulting from a range of confounding factors, but a primary cause is loss from pests and diseases, particularly insects. To improve productivity, recommendations for the mitigation of crop loss globally include early-warning and management systems for in-season indigenous pests. There are many early-warning systems in temperate regions; however, such systems are poorly established in Africa. This is in part due to the need for a combination of pest modeling, data handling and dissemination infrastructure, capacity, and resource provision. While each of these components is progressing in Africa, the means to successfully deploy such systems remain limited. To bridge this, the development of the Pest Risk Information Service (PRISE) began in 2017 for farmers in SSA. Implemented in Kenya, Ghana, Malawi, and Zambia, PRISE developed temperature-driven phenology models for major maize, bean, and tomato pests. Using downscaled and processed Earth Observation data to drive the models, PRISE partnered with African national agencies to communicate pre- and in-season pest alerts that forecast the time to act against key insect pests. Alerts were designed to be integrated into country-specific Good Agricultural Practice (GAP) recommendations to provide a complementary package to agricultural stakeholders. End line studies with farmers showed that those who received information about the target crops including PRISE pest forecasts, generally reported better outcomes in terms of reduced losses and increased incomes compared with farmers who did not.

Barriers to the uptake of solar-powered irrigation by smallholder farmers in sub-saharan Africa: A review

Irrigation expansion is critical for agricultural and rural development, food and nutrition security, and climate change adaptation in Sub-Saharan Africa (SSA). Lack of accessible energy for irrigation development due to limited off- and on-grid infrastructure and the resulting dependence on costly fuel-based irrigation have been key inhibiting factors for irrigation expansion in the region. Off-grid solar-powered irrigation pumps (SIPs) can overcome many of the energy access and other challenges in the region, but their uptake has been slow. Given the nascent development of the solar irrigation sector in SSA, this paper combines a review of the peer-reviewed and grey literature with key informant interviews to identify systemic barriers to the adoption and growth of solar-powered irrigation. We identify uncovered risks, lack of incentives, and lack of capacity as the key factors limiting the adoption of solar-powered irrigation. Moreover, despite significant global cost reductions, solar-powered irrigation systems remain costly in SSA due to limited market development and geographical constraints. Lack of regulation and low investment in building local institutions and value chains further affect uptake and inhibit leveraging the energy transition for ensuring food security and agriculture-led poverty alleviation in SSA. We propose a move away from thinking of SIPs as “silver bullets” and towards a systems approach and the design of context-specific solutions to address risks, incentives and capacity challenges.

Adaptive investment with land tenure and weather risk: Behavioral evidence from Tanzania

Two important risks faced by many smallholder farmers in Sub-Saharan Africa are erratic weather patterns and insecure land tenure. It is likely these risks will increasingly interact as projections of more erratic weather make small-scale farming more difficult and demand for rural land grows. This paper asks how farmers in Western Tanzania view these compound risks and the influence this has on levels of investment in adaptive agricultural technologies and the demand for land certification in a lab-in-the-field setting. Presenting novel data from a series of framed decision tasks linked to a household survey, this paper explores the relationship between individual risk preferences, adaptive investment and the demand for land certification from a group of 645 rural households in Kigoma, Tanzania. While adaptive investment increases with weather related risk, we find it responds negatively to land tenure risk. Individual risk preferences and past experiences of land disputes play significant roles in adaptive investment. Demand for land certification is high, investment increases significantly after certification, especially for risk-averse individuals.

Exploring mitigating factors for aflatoxin awareness and incidence among smallholder groundnut farmers in Sub-Saharan Africa

Abstract This study considers the association between agricultural extension, aflatoxin, and good management practices among smallholder groundnut farmers in sub-Saharan Africa. The first part examines extension and self-reported knowledge and perceptions of aflatoxin for three countries. This is done using pooled survey data (n = 1388) collected from 2014 to 2016, beginning with Uganda (n = 480) in 2014, Ghana (n = 537) in 2015, and Mozambique (n = 335) in 2016. Results from probit regressions suggest that aflatoxin knowledge and perceptions are related to village extension services, household head education, farm size, groundnut production area, and experience with aflatoxins. To build upon these findings, additional information on aflatoxin levels and good management practices for a sub-sample of the 2015 Ghana survey (n = 134) is analysed. Negative binomial regression estimates indicate significantly lower aflatoxin levels for households that (1) follow good management practices and (2) are in receipt of village extension services, with the lowest average aflatoxin level from the combination of (1) and (2). These findings underscore the role of extension in combating the incidence of aflatoxin in groundnut value chains. In this way, extension is associated with greater knowledge and perceptions, as well as lower levels of aflatoxin, that can be further reduced with good management practices.

Opportunities and challenges for conservation agriculture in Botswana

ABSTRACTConservation agriculture (CA) is being promoted as an energy efficient and cost-effective farming system that conserves soil and water and improves crop yields. Adoption of this farming system can contribute to attainment of Sustainable Development Goal (SDG) 2: end hunger, achieve food security and improved nutrition, and promote sustainable agriculture. However, the adoption rate of this new farming technique by smallholder farmers in sub-Saharan Africa (SSA) is low. The trade-offs and synergies related to the three pillars that anchor CA have not, however, been investigated in the context of Botswana. Farmers are faced with trade-offs in the use of crop residue in CA as mulch with traditional use as feed for livestock. This paper reviews the components of CA with a view to contribute to the development of CA strategies for Botswana. We show that adoption of CA in SSA is challenged by lack of weed control measures, the lack of a market for grain legumes and competing uses of crop residue. The paper highlights the discrepancy between CA methods and current government subsidies, issues that may restrain the adoption of CA in Botswana. The paper concludes by making recommendations for research and policy development for sustainable CA practices in Botswana.

A transformative poultry feed system: The impact of insects as an alternative and transformative poultry-based diet in sub-Saharan Africa

Abstract There is growing interest in the transformation of costly, unsustainable feed systems to help address malnutrition and food insecurity in sub-Saharan Africa (SSA). In the poultry production industry, dietary insect meals were identified as a possible solution to aid in transforming poultry feeds by replacing expensive and environmentally threatening protein feed ingredients including soyabean and fish meal. Hence, playing an important role in helping to feed the ever-growing human population size through the production of more poultry meat and meat products. The potential of edible insects as highly nutritious, cost-effective, and biofriendly alternative protein feed ingredient in poultry diets is currently one of the most trending topics in animal nutrition worldwide. This review will provide a recent overview of the utilisation of insect-based diets by poultry-producing farmers in SSA, to improve poultry production at low costs with little effect on climate change. Therefore, the perspectives of various farmers towards using insect-based diets in poultry production; recent findings on the effect of insect-based diets on poultry production and performance; benefits of insect-based poultry meat; adoption and awareness of insect farming; and opportunities and constrains of rearing insects for animal feeding in SSA were discussed. Hence, there is still a need to improve insect farming infrastructure, educating and training insect and poultry-producing farmers on insect rearing and marketing, enforcing laws and policies on insect farming operation, investing and conducting more research on local insects in poultry diets, as well as conserving wild insects and the environment in general.

Sustainable maize intensification through site-specific nutrient management advice: Experimental evidence from Nigeria

There is growing evidence on the impacts of site-specific nutrient management (SSNM) from Asia. The evidence for Sub-Saharan Africa (SSA), where SSNM developments are more recent and where conditions concerning soil fertility and fertilizer use differ importantly from those in Asia, is extremely scarce. We evaluate a SSNM advisory tool that allows extension agents to generate fertilizer recommendations tailored to the specific situation of an individual farmer’s field, using a three-year randomized controlled trial with 792 smallholder farmers in the maize belt of northern Nigeria. Two treatment arms were implemented: T1 and T2 both provide SSNM information on nutrient use and management, but T2 provides additional information on maize price distributions and the associated variability of expected returns to fertilizer use. We estimate average and heterogenous intent-to-treat effects on agronomic, economic and environmental plot-level outcomes. We find that T1 and T2 lead to substantial increases (up to 116%) in the adoption of good fertilizer management practices and T2 leads to incremental increases (up to 18%) in nutrient application rates, yields and revenues. Both treatments improve low levels of nutrient use efficiency and reduce high levels of greenhouse gas emission intensity, after two years of treatment. Our findings underscore the possibility of a more gradual and sustainable intensification of smallholder agriculture in SSA, as compared with the Asian Green Revolution, through increased fertilizer use accompanied by improved fertilizer management.

Sustainable intensification and food security: A panel data assessment of the smallholder maize farmers in Uganda

Food security is touted as an essential condition for social growth. Yet, the food deficit is rampant among smallholder farmers in sub-Saharan Africa. Besides, farm productivity is considered the theme for improving household food security outcomes. As one of the sub-Saharan African countries, Uganda is affected by food insecurity caused by the declining availability of cropped farmland. Sustainable intensification (SI) is a critical farming practice that enhances crop yield and reduces environmental degradation. However, there is scanty empirical evidence on if farming practices contributing to sustainable intensification can improve the household livelihood and food security. In this research, we used multinomial endogenous treatment effects and a balanced Uganda National Panel Survey to evaluate the impacts of SI technologies on maize farming households' livelihood and food security. We ranked households into four groups depending on the inputs and soil management practices they use on their maize farms, namely “non-adopters”, intensification group”, “sustainable group”, and “sustainable intensification group”. The multinomial endogenous treatment effect (METE) model's findings suggested using the SI cluster is associated with improved food consumption score, household dietary diversity score, and per capita expenditure using non-adopters as the baseline group. Further, these improvements are determined by combining maize-legume intercrop and inorganic fertilizer practices. The results indicate that experts and researchers should espouse multidimensional and all-inclusive technological evaluation methods instead of conservative reductionists methods that concentrate on a solo farming practice at a time. Also, the findings can guide the sustainable vector that highlights and strengthens all-inclusive agricultural growth with policymakers and scientists working with marginalized farmers.

Intermediate Technologies: The Key to Eradicating Post-harvest Losses (PHLs) in Sub-Saharan Africa (SSA)

Post-harvest losses (PHLs) in Sub-Saharan Africa (SSA) pose a significant threat to food security and economic stability. PHLs account for a substantial portion of food waste and economic losses. This paper explores the potential of intermediate technologies in addressing this challenge. Intermediate technologies, including hand-operated, pedal-operated, and solar-powered devices, offer adaptable and cost-effective solutions tailored to the needs of smallholder farmers who make up the majority of SSA's agricultural sector. These technologies bridge the gap between labor-intensive traditional methods and high-end, expensive equipment. They enhance efficiency, reduce labor, and have the potential to revolutionize post-harvest processes. Additionally, emerging innovations, such as harnessing energy from footsteps and raindrop energy offer promising avenues for further enhancing the sustainability and efficiency of post-harvest operations in resource-constrained environments. Intermediate technologies represent not only tools but also catalysts for transformation. They hold the key to reducing PHLs, fostering economic growth, ensuring food security, and leading to sustainable agriculture in SSA. By harnessing these technologies' adaptability and resource efficiency, SSA can move closer to a more sustainable and prosperous future.
