UAVs—unmanned aerial vehicles—facilitate data acquisition at temporal and spatial scales that still remain unachievable for traditional remote sensing platforms. However, current legal frameworks that regulate UAVs present significant barriers to research and development. To highlight the importance, impact, and diversity of UAV regulations, this paper provides an exploratory investigation of UAV regulations on the global scale. For this, the methodological approach consists of a research synthesis of UAV regulations, including a thorough literature review and a comparative analysis of national regulatory frameworks. Similarities and contrasting elements in the various national UAV regulations are explored including their statuses from the perspectives of past, present, and future trends. Since the early 2000s, countries have gradually established national legal frameworks. Although all UAV regulations have one common goal—minimizing the risks to other airspace users and to both people and property on the ground—the results reveal distinct variations in all the compared variables. Furthermore, besides the clear presence of legal frameworks, market forces such as industry design standards and reliable information about UAVs as public goods are expected to shape future developments.

Land is a precious resource in the Ethiopian highlands, where the entire agricultural system depends on rain-fed system. The resource faces multiple interconnected environmental and socioeconomic challenges. Among these, the absence of tenure security has significantly affected farmers’ willingness to adopt soil and water conservation practices (SWCPs), leading to a decline in land productivity, hindering household food security, and contributing to an increase in land-related disputes. Bearing this in mind, the government of Ethiopia (GoE) has undertaken two rounds of land certification programs in selected regions, one of which was Amhara National Regional State (ANRS). This study examined how land certification strengthens tenure security, lowers land-related disputes, motivates farmers to employ SWCPs, and raises the productivity of farm plots in Dessie Zuria and Kutaber Woredas. The research followed an exploratory survey method which utilized both qualitative and quantitative data. The survey involved purposefully selected 401 household heads. Additionally, cross sectional data were collected from various sources, including Woreda and zonal agriculture, court, land, and Natural Resource Management (NRM) offices. Quantitative data were analyzed using frequency tables, percentages, graphs, figures, cross-tabulation, and descriptive statistical methods. Meanwhile, qualitative data were transcribed, grouped, and interpreted in line with the research’s objectives. SPSS software version 26 was used for data analysis. The findings denoted a positive relationship between land certification and tenure security. Furthermore, enhanced tenure security has played a positive role in reducing land-related disputes, initiating farmers to invest in SWC practices and improving the productivity of farm plots. The research suggests the adoption of a cadastral land registration system, the encouragement of community involvement, and the enforcement of laws and bylaws. The research recommend implementation of cadastral land registration system, promote community participation, and enforcement of laws and bylaws. The work has implications for development practitioners, academia and policymakers working on land tenure, SWC practices, and food security.

There exists a demand for effective land administration systems that can support the protection of unrecorded land rights, thereby assisting to reduce poverty and support national development—in alignment with target 1.4 of UN Sustainable Development Goals (SDGs). It is estimated that only 30% of the world’s population has documented land rights recorded within a formal land administration system. In response, we developed, adapted, applied, and tested innovative remote sensing methodologies to support land rights mapping, including (1) a unique ontological analysis approach using smart sketch maps (SmartSkeMa); (2) unmanned aerial vehicle application (UAV); and (3) automatic boundary extraction (ABE) techniques, based on the acquired UAV images. To assess the applicability of the remote sensing methodologies several aspects were studied: (1) user needs, (2) the proposed methodologies responses to those needs, and (3) examine broader governance implications related to scaling the suggested approaches. The case location of Kajiado, Kenya is selected. A combination of quantitative and qualitative results resulted from fieldwork and workshops, taking into account both social and technical aspects. The results show that SmartSkeMa was potentially a versatile and community-responsive land data acquisition tool requiring little expertise to be used, UAVs were identified as having a high potential for creating up-to-date base maps able to support the current land administration system, and automatic boundary extraction is an effective method to demarcate physical and visible boundaries compared to traditional methodologies and manual delineation for land tenure mapping activities.
