Despite huge government spending on concrete infrastructure, Nigeria still faces recurrent flooding issues. Therefore, the study was conducted to assess ecosystem-based forestry land use (EFLU) for flood risk mitigation and socio-livelihood supports in South West Nigeria. A multistage procedure was applied in this research. The initial two stages involved purposive sampling of Oyo, Ogun, and Lagos States, with two local government areas (LGAs) selected from each state, followed by a third stage of random selection of 22 communities in each of the LGA, based on past incidences of flood. In the fourth stage, households listing was used to systematically select 250 households. Questionnaire administration was adopted for data collection. Data analysis utilised descriptive statistics, ranking and chi-square test at α0.05. Findings showed extent of awareness on discouraging refuse and waste dump into drainages and rivers ranked 1st while other government’s intervention were ranked below 1.5 mean scores benchmark. In addition, for EFLU; tree planting and conservation of trees were ranked 1st and the latter ranked 2nd, respectively. This suggested that tree planting and conservation are well-promoted initiatives, but other EFLU may require more attention to increase their impacts. Furthermore, there was a significant relationship between extent of awareness and trees conservation in upland areas. Therefore, the study recommends consistent promotion and support tree planting and conservation initiatives, with effective engagement of local communities to promote environmental awareness, to curb climate change disaster.

In Central Uganda, farmers are investing in high value crops, such as hot pepper (Capsicum annum), French beans (Phaseolus spp.), and okra (Abelmoschus esculentus) to meet household needs. Based on data from 273 adopters, this study identified priority household needs, assessed profitability of the crops, and evaluated the extent to which the crops address household objectives. School fees emerged as the foremost priority, followed by, among others, trade investment, liquidity, land acquisition, and healthcare. A gross margin analysis confirmed profitability, with French beans yielding the highest, (US$ 1,003 ha⁻¹), followed by hot pepper (US$ 816 ha⁻¹) and okra (US$ 783 ha⁻¹). Despite contributing about one-third of household income, production of these crops remains constrained by small land parcels (0.03–0.10 ha), high input costs, and limited advisory services, meaning only school fees were fully met. The findings highlight the need for interventions that strengthen market access, stabilise prices, and enhance productivity through irrigation, fertilisers, mechanisation, and improved varieties. Linking agricultural income to education financing is critical, while extension services, climate-smart practices, crop insurance, and public–private partnerships can reduce risks and improve access to inputs. Scaling up production and diversifying activities will enable households to meet a broader range of needs.

Cassava is a critical staple crop for food security and livelihoods across sub-Saharan Africa, yet its production dynamics vary significantly between major producing nations. This study conducts a comparative analysis of cassava production trends, drivers of change, and sources of instability from 1993 to 2024 in five leading African producers: Angola, Congo, Ghana, Nigeria, and Tanzania. Utilising a decomposition analysis framework on FAO time-series data, the research quantifies the contributions of area expansion and yield improvement to production growth and identifies the statistical components of output volatility. The results reveal two distinct models: Ghana exemplifies a productivity-led intensification path, where rising yields contributed most to growth, while Nigeria and Tanzania followed an area-driven extensification model, where massive land expansion offset declining yields and introduced higher instability linked to volatile area allocation. Angola and Congo demonstrated more balanced growth. The primary sources of instability differed, with Nigeria&apos;s risk dominated by fluctuations in cultivated area and Ghana&apos;s by increasing yield variance. The study concludes that sustainable growth in the cassava sector requires a strategic shift from extensification to intensification. Policy implications advocate for differentiated national strategies prioritising investment in yield-enhancing technologies, climate-resilient practices, and stabilised land-use policies to ensure long-term productivity and reduced volatility.

This article examines the use of temporary associations of undertakings (associazioni temporanee di imprese, ‘ATI’) in Italian agrivoltaic projects, a contractual architecture increasingly adopted to integrate energy generation with continued agricultural activity under the PNRR incentive scheme. The study reconstructs the private-law structure of the ATI and tests its operational resilience against the MiTE Guidelines of 27 June 2022 and the binding framework introduced by Ministerial Decree of 22 December 2023, No 436, as implemented through the GSE Operational Rules. Methodologically, the analysis combines doctrinal and systematic interpretation of the Italian Civil Code’s agency/representation tools with a regulatory reading of the incentive requirements and their documentary conditionality. The article shows that agrivoltaic ATIs cannot be meaningfully framed through the ‘horizontal/vertical’ categories of public procurement, because energy and agriculture are interdependent and equally necessary components of project qualification. It concludes that bankability and compliance depend on drafting an ‘Agency Arrangement’, internal governance rules, technical annexes and an agricultural management plan capable of ensuring continuity of farming, traceability, and allocative clarity of responsibilities, including for changes in participating entities. Finally, it identifies minimum contractual safeguards to align permitting titles with incentive entitlement and to manage ATI–SPV transitions without jeopardising eligibility.
