“…Processes of LULC change are broad categories of landscape change and not the actual causes of land modifications, as considered in previous studies (Huang et al, 2012;Manandhar et al, 2010). The approach followed in this study is more appropriate for the identification of driving forces linked to LULC change.…”

“…Previous studies showed that LULC detection analysis should consider different spatial scales, since landscape patterns might change with the resolution of maps (Manandhar et al, 2010). Coarser resolutions tend to show less swap and less inter-class transitions, and yet they can be very useful in finding the distances over which the change occurs (Pontius et al, 2004).…”

“…Random transitions are influenced by coincidental or unique processes of change, whereas systematic transitions are those that tend to evolve in a consistent and/or progressive manner due to population growth, industrial or commercial expansion, or changes in land management policies (Braimoh, 2006;Lambin et al, 2003). The identification of systematic transitions makes it possible to focus on the strongest signals of landscape change and ultimately to link pattern to process (Manandhar et al, 2010;Pontius et al, 2004). Pontius et al (2004) proposed a methodology to assess inter-category transitions based on systematic transitions while accounting for land persistence.…”

• LULC and LULC changes are important drivers of water condition.• We identified strong signals of systematic transitions.• Consistency and magnitude of systematic transitions reveal processes of LULC change.• Processes of LULC change reveal important drivers of water condition.• Relevant drivers reveal potential pressures linked to the process of transition. Land use and land cover (LULC) are driving forces that potentially exert pressures on water bodies, which are most commonly quantified by simply obtained aggregated data. However, this is insufficient to detect the drivers that arise from the landscape change itself. To achieve this objective one must distinguish between random and systematic transitions and identify the transitions that show strong signals of change, since these will make it possible to identify the transitions that have evolved due to population growth, industrial expansion and/or changes in land management policies. Our goal is to describe a method to characterize driving forces both from LULC and dominant LULC changes, recognizing that the presence of certain LULC classes as well as the processes of transition to other uses are both sources of stress with potential effects on the condition of water bodies. This paper first quantifies the driving forces from LULC and also from processes of LULC change for three nested regions within the Mondego river basin in 1990, 2000 and 2006. It then discusses the implications for the environmental water body condition and management policies. The fingerprint left on the landscape by some of the dominant changes found, such as urbanization and industrial expansion, is, as expected, low due to their proportion in the geographic regions under study, yet their magnitude of change and consistency reveal strong signals of change regarding the pressures acting in the system. Assessing dominant LULC changes is vital for a comprehensive study of driving forces with potential impacts on water condition.

“…In this regard, López and Plata (2009) proposed that the enormous magnitude of persistence, compared with changes, could lead to erroneous conclusions about the dynamics of the territory. Thus, it becomes interesting to analyze the data outside the main diagonal because they help identify key and systematic patterns of change separate from any persistence level and land cover size (Pontius et al, 2004;Braimoh, 2006;Manandhar et al, 2010;Gutiérrez and Grau, 2014). Table 4 presents the transitions based on the most significant gains between land covers.…”

The results confirmed the reduction in the areas of agriculture and livestock and the increase of exotic plantations use on surfaces intended for agricultural use. The significant transitions were the conversion at a rate gain of 384 ha/year of "Farmlands" to "Exotic plantations", the abandonment at a loss rate of 119 ha/year of "Perennial grasslands" to "Native vegetation", the degradation at a loss rate of 93 ha/year of "Native vegetation" to "Perennial grassland", and the revegetation at a rate gain of 60 ha/year of "Exotic plantations" to "Native vegetation". The new patterns and trends in the use and intensity of land use reaffirmed the need for studies on the updated status of natural resources, particularly soil resources. This work, we believe, is a technical tool to support the sustainable management of a territory and the decision-making processes on land use.

“…Land use transitions can be detected by statistical evaluation by comparing different temporal pattern maps. A common method employs the use of a land use/cover transition matrix, which provides a cross-tabulation matrix including change quantities and directions, and allows identification of differences between random and systematic land use transitions [14][15][16][17]. However, matrix-based land use studies mainly focus on overall gains and losses, and tend to ignore the spatial locations and swap changes of land use transitions [10,18].…”

Long-term intensive land use/cover changes (LUCCs) of the Yellow River Delta (YRD) have been happening since the 1960s. The land use patterns of the LUCCs are crucial for bio-diversity conservation and/or sustainable development. This study quantified patterns of the LUCCs, explored the systematic transitions, and identified wetland change trajectory for the period 1976-2014 in the YRD. Landsat imageries of 1976, 1984, 1995, 2006, and 2014 were used to derive nine land use classes. Post classification change detection analysis based on enhanced transition matrix was applied to identify land use dynamics and trajectory of wetland change. The five cartographic outputs for changes in land use underlined major decreases in natural wetland areas and increases in artificial wetland and non-wetland, especially aquafarms, salt pans and construction lands. The systematic transitions in the YRD were wetland degradation, wetland artificialization, and urbanization. Wetland change trajectory results demonstrated that the main wetland changes were wetland degradation and wetland artificialization. Coastline change is the subordinate reason for natural wetland degradation in comparison with human activities. The results of this study allowed for an improvement in the understanding of the LUCC processes and enabled researchers and planners to focus on the most important signals of systematic landscape transitions while also allowing for a better understanding of the proximate causes of changes.
