This study employs system theory and dynamic modeling to investigate how rural homestead rights confirmation influences multidimensional urban–rural integration. Through constructing a system dynamics model incorporating environmental, economic, and social sustainability indicators, an analysis of the structural relationships between land tenure security, resource mobility, and balanced regional development is conducted. The findings reveal that formalized property rights act as a systemic intervention triggering three synergistic effects: (1) enhanced rural resource utilization efficiency, (2) accelerated elements market integration, and (3) improved social equity in development opportunities. Scenario simulations project that, under current policy trajectories, urban–rural integration could achieve intermediate coordination by 2035 through sustainable land management practices. A comparative scenario analysis demonstrates that urban-priority models exacerbate spatial inequality, while rural-optimized and coordinated development pathways accelerate convergence toward comprehensive integration through ecological–economic–social multi-dimensional synergy. This research contributes to sustainability science by quantifying the systemic linkages between institutional innovation and spatial justice, providing evidence-based insights for developing countries pursuing integrated rural revitalization and sustainable urbanization strategies. The methodological framework offers replicable tools for assessing institutional reforms’ long-term impacts on territorial sustainability. Full article

This study investigates the gendered nexus between climate change, food insecurity, and conflict in Plateau State, Nigeria. This region in north-central Nigeria is marked by recurring farmer–herder clashes and climate-induced environmental degradation. Drawing on qualitative methods, including interviews, gender-disaggregated focus groups, and key informant discussions, the research explores how climate variability and violent conflict interact to exacerbate household food insecurity. The methodology allows the capture of nuanced perspectives and lived experiences, particularly emphasizing the differentiated impacts on women and men. The findings reveal that irregular rainfall patterns, declining agricultural yields, and escalating violence have disrupted traditional farming systems and undermined rural livelihoods. The study also shows that women, though they are responsible for household food management, face disproportionate burdens due to restricted mobility, limited access to resources, and a heightened exposure to gender-based violence. Grounded in Conflict Theory, Frustration–Aggression Theory, and Feminist Political Ecology, the analysis shows how intersecting vulnerabilities, such as gender, age, and socioeconomic status, shape experiences of food insecurity and adaptation strategies. Women often find creative and local ways to cope with challenges, including seed preservation, rationing, and informal trade. However, systemic barriers continue to hinder sustainable progress. This study emphasized the need for integrating gender-sensitive interventions into policy frameworks, such as land tenure reforms, targeted agricultural support for women, and improved security measures, to effectively mitigate food insecurity and promote sustainable livelihoods, especially in conflict-affected regions.

African cities are experiencing rapid, unregulated growth, characterized by high land pressure and growing demand for housing and urban infrastructure. New arrivals often settle in vulnerable areas (wetlands, hills, flood) where land is cheaper and unregulated by public authorities. This type of settlement is accompanied by numerous land conflicts, exacerbated by the coexistence of formal and customary land tenure systems, which struggle to harmonize. In this context, public land regulation policies often remain centralized and ill-adapted, revealing their limitations in ensuring equitable and sustainable management of urban land. Faced with this gap, our systematic study explores the socio-environmental dynamics of this normative pluralism in land governance within Cameroonian cities. Our findings highlight the tensions and opportunities of this complex coexistence, which vary significantly according to city size (small, medium, and large), the colonial heritage (Francophone and Anglophone), and the dominant legal framework (civil law and common law). The analysis highlights the need to take into account historical, linguistic, and politico-administrative roots, which profoundly influence local forms of the institutionalization of normative pluralism and the associated socio-environmental vulnerabilities. This normative plurality underlines the importance of a hybrid system of land governance capable of integrating local specificities while ensuring land security for all. Future research will include comparisons with other African countries in order to understand transferable mechanisms for better land governance. Full article

Climate change and variability are characterized by unpredictable and extreme weather events. They adversely impact the highly susceptible smallholder farmers in sub-Saharan Africa, who heavily rely on rain-fed agriculture. Climate smart agriculture (CSA) practices have been extensively promoted as offering long-term solutions to changing climate conditions, while enhancing the productivity and sustainability of African agricultural systems. Despite this, the adoption rate remains low among smallholder farmers. Understanding the factors that influence adoption of these practices among this key farming community is therefore necessary to increase their adoption. In this paper, we review and summarize findings from existing studies on the factors that influence the adoption of CSA practices by smallholder farmers in sub-Saharan Africa. Our review reveals that land tenure security, access to information and extension services, and affiliation to group membership positively influence adoption. On the other hand, gender, risk perception, and off-farm income had conflicting effects by reporting both positive and negative influences on CSA adoption. We conclude that CSA adoption options are local-specific, and their development and implementation should emphasize locally tailored knowledge, skills, and resources. Full article

The time is nigh to organize the physical landscapes of the United States under a unified land use policy and planning framework. As human populations have steadily grown, so has the urgency for agencies to plan for land uses at broader scales to overcome continued jurisdictional fragmentation and achieve sustainable and environmentally just landscapes. This paper introduces a vision, conceptual approach, and implementation strategy that applies ecoregions and proposes a unified framework for land use planning and regulation in the United States. The Sustainable Ecoregion Program (SEP) is designed to enable local landowners; public stakeholders; other land users; and state, regional, tribal, and national natural resource professionals to set and achieve future desired conditions for sustainable land uses across landscapes. The objective is to outline a comprehensive and sustainably just solution to the recurring problem of managing conflicting land uses in the face of continued degradation and multiple land tenure systems. The SEP will determine how much of the physical landscape will go to developed, agricultural, and natural landcover types. The framework includes recognition of level III ecoregions as primary boundaries, proposed secondary boundaries and shapes to enhance connectivity and movement across landscapes, a proposed structure for the environmental governance and co-management of landscapes, and definitions of physical landscape types. The benefits and challenges of the SEP are discussed. The outcomes of the SEP include ecological integrity, sustainable land use management, deliberative democracy, just sustainability, and improved quality of life for residents of the United States.

Ensuring food security and sustainable land management is a global priority, particularly within countries participating in the Belt and Road Initiative (BRI). This study investigates the role of cultivated land regulation systems in influencing agricultural productivity and trade efficiency, focusing on China, Russia, and Kyrgyzstan. Despite the critical role of cultivated land, variations in land-regulation policies and regional practices have led to disparate outcomes in agricultural productivity, sustainability, and trade efficiency. A comparative methodology was employed, integrating descriptive statistics, regression modeling, and geospatial analysis to evaluate yield trends, irrigation coverage, land-use efficiency, and trade performance between 2016 and 2022. Data were sourced from government reports, international databases, and satellite imagery. The results indicate that China’s centralized land-regulation policies—such as the Red Line Policy—have stabilized arable land, enhanced average crop yields (6.1 tons/ha in 2022), and significantly expanded agricultural export volumes. In Russia, land consolidation and modernization efforts have improved productivity (2.9 tons/ha in 2022) and export capacities, though limited irrigation remains a challenge. Kyrgyzstan, while showing gradual improvements through cooperative farming, continues to face fragmentation, infrastructure deficiencies, and limited trade growth. The study concludes that harmonized and targeted land-regulation policies—coupled with infrastructure investments and regulatory alignment—are essential to secure productivity, improve trade efficiency, and strengthen agricultural resilience across BRI countries. Strengthened investments in infrastructure, land-tenure security, and policy alignment across BRI countries are recommended to enhance food security and agricultural trade efficiency. Full article

Uganda is gradually transitioning from communal to private land tenure systems. However, establishing privatized land rights has faced ongoing criticism, particularly concerning their impact on vulnerable groups. Despite the enactment of a national land policy, its benefits have not fully reached rural populations. Issues of land tenure insecurity and unclear ownership continue to generate confusion and have reportedly weakened traditional communal land systems, undermining sustainable agricultural production and long-term investment. This paper examines rural land rights, land markets, and the broader structural transformation of Uganda’s land sector, drawing on the existing literature and published reports. This review reveals that land tenure and administrative challenges persist, largely due to the dominance of customary tenure systems. Although land markets are active, they remain imperfect due to tenure insecurity and legal ambiguities. The findings highlight the need for increased public sensitization regarding land policy, gender-sensitive policies that promote joint ownership, continuous incentives for formalization, the acquisition of land documents, and the harmonization and strengthening of relevant land governance institutions.

Positional accuracy in cadastral data is fundamental for secure land tenure and efficient land administration. However, many land administration systems (LASs) experience difficulties to meet accuracy standards, particularly when data come from various sources or historical maps, leading to disruptions in land transactions. This study investigates the use of unsupervised clustering algorithms to identify and characterize systematic spatial error patterns in cadastral maps. We compare Fuzzy c-means (FCM), Density-Based Spatial Clustering of Applications with Noise (DBSCAN), and Gaussian Mixture Models (GMMs) in clustering error vectors using two different case studies from Greece, each with different error origins. The analysis revealed distinctly different error structures: a systematic rotational pattern surrounding a central random-error zone in the first, versus localized gross errors alongside regions of different discrepancies in the second. Algorithm performance was context-dependent: GMMs excelled, providing the most interpretable partitioning of multiple error levels, including gross errors; DBSCAN succeeded at isolating the dominant systematic error from noise. However, FCM struggled to capture the complex spatial nature of errors in both cases. Through the automated identification of problematic regions with different error characteristics, the proposed approach provides actionable insights for targeted, cost-effective cadastral renewal. This aligns with fit-for-purpose land administration principles, supporting progressive improvements towards more reliable cadastral data and offering a novel methodology applicable to other LASs facing similar challenges.

Metropolitan areas increasingly confront complex challenges related to food security, social inequality, environmental degradation, and resource scarcity, exacerbated by rapid urbanization, climate change, and the reliance on extended, fragile supply chains. Urban and peri-urban agriculture (UPA) is recognized as a promising approach to mitigate these issues. For example, it enhances food security and nutrition by strengthening local food supply systems, improves livelihoods by providing employment and income for local residents, and promotes environmental sustainability through the creation of greening spaces and reduction of food miles. However, the full potential of UPA remains constrained by various technological, economic, and social barriers, such as limited growing spaces, lack of land tenure security, low economic efficiency, and insufficient public awareness and acceptance. Given that the technological innovations are critical in overcoming these barriers and maximizing the positive impacts of UPA, this review provides a state-of-the-art overview of advanced technologies and tools applicable to UPA, aiming to inform how these innovations can be better enabled to enhance UPA’s contributions to sustainable urban food systems. The review begins by defining UPA, categorizing its various forms, and exploring its multifunctional roles within urban contexts. It then presents a thorough analysis of a range of UPA technologies that serve specific purposes, including productivity and product quality improvement, space utilization optimization, resource recycling, and land use management. Furthermore, the review evaluates the current challenges faced by these technologies throughout the stages of research and development (R&D), dissemination and extension, and application and commercialization, employing an analytical framework adapted from Technology Life Cycle theories. In conclusion, the review emphasizes the crucial roles that UPA and relevant technological innovations play in transforming food systems and urban environments. It proposes four key recommendations: (1) enhancing funding mechanisms and fostering interdisciplinary collaboration for UPA R&D, (2) strengthening UPA technology dissemination systems, (3) promoting economic feasibility and market integration within UPA business models, and (4) establishing supportive environments among all stakeholders in the innovation process. These targeted strategies are essential for scaling UPA technologies, thereby strengthening food security, environmental sustainability, and socio-economic resilience in metropolitan areas.

This paper looks into the impact of China’s new rural land reform, the three rights separation policy (TRSP), on Chinese farmers’ income. Based on data collected from 360 rural households in Anhui Province, China, 2021, this paper constructed the influence pathways of the TRSP on household income and estimated the effects along different pathways using the structural equation model (SEM) model. It showed that through expanding the planting scale and promoting resource-use efficiency, the new land tenure system can indirectly increase transfer-in household income. However, the TRSP has a significant negative direct effect on transfer-out households’ income, and only a slight impact on transferring rural labor to other industries or relaxing the liquidity constraint. In short, the TRSP’s effect on income gains is more prominent in transfer-in households than transfer-out ones, which in the long run would lead to an increased income gap, more so if transfer-out households lack easy access to non-farm employment. Our findings suggest that public authorities should respect farmers’ autonomy in land transfer decisions and pay special attention to labor transfer in poverty alleviation. Meanwhile, widening income disparities among different groups should be heeded while implementing local governments’ service roles. Full article

The linkage between land tenure security and land quality improvement investment is crucial given that the land tenure security system is a widely applied policy tool for the protection of cultivation land in developing countries. Drawing on the triple land tenure security framework, this paper examines the impact of the de jure and the de facto land tenure security on farming households’ decisions about using organic fertilizer on their plots in China, based on a national survey dataset covering 2308 plots matched with 962 farming households across 8 provinces in China (Shangdong, Shangxi, Jilin, Zhejiang, Henan, Gansu, Hunan, and Sichuan) from January to July 2013. The empirical results show that the de facto land tenure security affected the use of organic fertilizer by the farming households positively. In comparison, the impact of the de jure land tenure security on the use of organic fertilizer by farming households was modest. It is suggested that the government should implement the policies effectively to promote de jure land tenure security and encourage farming households to make sustainable land investment.

Forest management plans are the bibles of forest management. On the basis of these plans, farmers play essential roles in forest cultivation, protection, and utilization. After the forest tenure reform in the 2000s in China, the status of farmers has changed. For example, collective management has decreased and household management has become a leading structure of operation and management. Farmer’s dependence on income from forests has increased, which is reflected in their increased participation in management. However, insights into farmers’ perceptions of and willingness to participate in the formulation of forest management plans are insufficient. This study analyzes the factors influencing farmers’ participation by using an econometric model based on 1752 samples of farmer households from 10 counties. The empirical results reveal that according to farmers, forest type and property rights influence their willingness to participate in the formulation of forest management plans. In addition, whether there is a village leader, the village distance from town, the circulation of forest land, the area of woodland, timber price, and forestry income have a significant positive impact on farmers’ willingness to participate in forest management plan formulation; the level of education and non-agricultural income have a significant negative impact on farmers’ willingness to participate in forest management program development. Finally, this study proposes to improve and deepen the reform of the forest ownership system, encourage land circulation, and give play to the role of village leaders in promoting the participation of farmers in forest management plans, so as to improve the efficiency of forest management.

Cities in West Africa have master and local plans to plan and guide land use and prevent urban sprawl. However, their spatial growth is not in line with the principles and indicators of harmonious development. To what extent has the spatial growth of these cities been shaped by urban development plans? This article assesses the ability of master and local plans to guide and frame urban development in Ho in Ghana and Kpalimé in Togo, using compliance and performance approaches. Combining interviews with municipal and traditional authorities, statutory land administration officials, and urban planners, this study finds that urban development in Ho has an average compliance rate of between 54% and 72%, compared to a rate of between 13% and 24% in Kpalimé. In terms of performance, Ho’s local plans outperform Kpalimé’s master plans. The master plans influence the plans below Ho, which is not the case in Kpalimé, where there is no link between the plans. The moderate performance of Ho and the poor performance of Kpalimé can be explained by several factors, such as the non-participatory approach to planning, the land tenure system, the lack of political support, and the lack of human and financial resources.

Mangrove Swamp Rice is a unique labour-, time-, and knowledge-intensive farming system across West Africa requiring a complex water management through dikes, canals, and pipes. Cooperation is crucial in the socio-spatial and temporal organisation of water management, helping mitigate risks like saltwater intrusion, prolonged submersion, and drying of paddies, particularly intensified by climate change. We adopted a mixed-methods approach integrating grounded theory with case study design and multi-level analysis and employed several tools, such as social network analysis, a land tenure register, a digital elevation model, and a machine learning model. This research strategy allowed us to gain an in-depth understanding of the complex socio-ecological system in water management. Our study examined the benefits of cooperation for water infrastructure management, highlighting its critical role in routine monitoring and repair, specialised technical advice, and annual belt dike maintenance. Within the large array of factors influencing cooperation, key drivers, such as spatial proximity and farmers’ technical knowledge, labour ethics, and fame, emerged and are discussed. Our findings provide important insights into the social organisation of “traditional” societies and offer valuable guidance for development practitioners, emphasising the importance of involving reputed farmers for sustainable socio-technical adaptation.

Sustainable agricultural practices (SAPs) remain the panacea to addressing challenges relating to climate change, low rainfall, and low agricultural productivity in many rural parts of sub-Saharan Africa (SSA). These practices include but are not limited to crop rotation, intercropping, cover cropping, and conservation tillage. The aforementioned practices have been scientifically proven to enhance crop productivity while safeguarding environmental resources. This review assesses the trends, effectiveness, and challenges associated with the adoption and utilization of SAPs among smallholder farmers in the SSA region, analyzing the literature and reports from 2000 to 2024 sourced from databases such as Google Scholar and Scopus. The inclusion criteria focused on key concepts such as SAPs, adoption, and challenges. Findings indicate that crop rotation, intercropping, improved seed varieties, manure, and mulching are among the most adopted practices. In reality, practices such as conservation tillage, agroforestry, and water harvesting systems remain the least adopted practices in many rural parts of SSA. The review further reveals that challenges relating to land tenure insecurity, lack of knowledge, training, and limited access to financial institutions all have a direct or indirect influence on farmers’ choice of adoption. Overcoming the aforementioned challenges through policy interventions and capacity building is vital for improved crop productivity and rural livelihoods. Full article
