“…The regulation of the flow, the introduction of exotic species, and the change of land cover determine the alteration of riparian ecosystems, causing important impacts [9][10][11]. In this way, in the area of influence of a river, loss of land cover can be identified due to the fragmentation of the land in order to conduct the construction of houses, industries, and productive plots [12][13][14][15][16].…”

The predominant aim of the current study was to evaluate the spatial dynamics of the riparian coverage of the area of influence of the Chambo River in the area of the river’s source (middle-high basin), between 2500 and 3000 m.a.s.l. For its execution, Landsat 7 images from the year 2000, RapidEye from the year 2009, and Spot 6 from the year 2019 were used in the time range of 2000–2009 and 2009–2019. These were subjected to supervised classification by applying the maximum likelihood algorithm, identifying five classes of soil cover, being pasture, crops, soil-remnants of paramo, forest, and anthropic. The classification results were validated by calculating the precision measures and the kappa index. With the use of cross-tabulation matrices, the gains, losses, and persistence in the two periods studied were identified. There, it was determined that, in the first study period, the soil cover-paramo remnants presented the highest percentage of loss (26.70%), the crop cover the highest percentage of gain (28.91%), and in the second period, the crop class presented the highest percentages of losses (18.94%) and gains (17.29%). The cartographic projection of the area for the year 2030 predicts that the areas anthropic category will increase by 1.27%, that of forest will decrease by 1.19%, that of soil-remnants of paramo will gain 0.79%, and crop and pasture cover will decrease by 0.45% and 0.43%, respectively. The results obtained allow for the transitions between coverages to be attributed to population growth, afforestation, reforestation, deforestation and agricultural activities, volcanic eruptions, land colonization, and expansion of agricultural activity. Complementary studies are recommended that involve livelihoods and water quality, which facilitate the identification of vulnerable areas to propose adaptation, prevention, and/or restoration measures.

Computer programs are an essential ally for fulfilling the Sustainable Development Goals (SDGs). They offer enormous potential for accelerating said fulfillment and reducing the cost of implementation processes. Our objectives in this Galapagos Islands case study were: i) to quantify the proportion of male and female inhabitants, separated by ethnicity, ii) to identify the number of dwellings distributed at urban and rural levels according to their typology, and iii) to determine the proportion of dwellings that are supplied with water. The Galapagos Islands are located 1000 km from mainland Ecuador. The program used was REDATAM Version 7 (Microcomputer Data Recovery for Small Areas), which specializes in processing microdata from population and housing censuses. The unit of investigation was the dwellings, and within them, the households and household members who are habitual residents in the province of Galapagos and who were in the 2015 census. It was identified that at the provincial level, 51.20% are male and 48. 80% are female, and the most populous canton is Santa Cruz. The population is divided into six ethnic groups heterogeneously between urban and rural sectors and between cantons. There are no group housing projects at the rural level for preventive or remedial assistance for the population, and there is a deficit in terms of water supply to the rural sector. Therefore, local authorities must promote programs to improve the living conditions of rural and urban dwellers to work toward complying with the goals of the Sustainable Development Goals, as outlined in the 2030 Agenda. Keywords: 2030 Agenda; census, development, demography sustainable.

“…Land use and land cover change (LULC) has become a fundamental and essential component in current strategies that concern monitoring environmental change and managing natural resources [1,2]. Increasing anthropogenic activities around the biosphere are causing large-scale alterations to the Earth's land surface, affecting the efficiency of global systems [3].…”

“…A better understanding of land dynamics requires the detection of LULC changes [22]. Empirical studies by researchers from various disciplines have shown that changes in LULC are key to various applications, such as hydrology, agriculture, forestry, the environment, geology, and ecology [1,2,23,24]. Many researchers argue that LULC change could result in an ecosystem imbalance and impacts on the environment caused by humans and their role in climate change [25][26][27][28].…”

Land use and land cover change (LULC) is an essential component for the monitoring environmental change and managing natural resources in areas of high natural and cultural biodiversity, such as the Amazon biome. This study was conducted in in the northern Amazon of Ecuador, specifically in the Diversity and Life Zone (DLZ) of the Yasuní Biosphere Reserve (YBR). The general aim was to investigate the territorial dynamics of land use/land cover changes to support policies for environmental and sociocultural protection in the DLZ. Specific objectives included (i) mapping LULC spatial and temporal dynamics in the DLZ in the period from 1999 to 2018, (ii) identifying sensitive LULC hotspots within the DLZ, and (iii) defining the possible policy implications for sustainable land use in the DLZ. Multitemporal satellite imagery from the Landsat series was used to map changes in LULC, which were divided into three-time stages (1999–2009, 2009–2018, 1999–2018). We adopted open-access Landsat images downloaded from the United States Geological Survey (USGS). The processes for assessing LULC in the DLZ included (1) data collection and analysis, (2) data processing for remote sensing, (3) thematic land cover, and (4) homogenization and vectorization of images. The results showed that in the period 1999–2018, most of the uses and land cover were transformed into pastures in the DLZ. Therefore, it is important to improve territorial planning, to avoid conflicts between indigenous populations, migrant settlers, and uncontacted indigenous populations that live in the DLZ, within the YBR.
