Remote sensing plays an important role in the continuous observation of the earth's surface. It produces large databases that can be used to map and monitor natural resources. To this end, land-use maps are genuine planning and decision-making tools for natural resource management. The aim of this study is to use remote sensing products to show the dynamics of land use, to understand these dynamics and their impact on water resources in general and on hydrology in particular. Specifically, it is a question of identifying the similarities and differences that have occurred, and finally evaluating the rate of change. The methodology adopted is the use of the likelihood algorithm to produce three thematic classifications for the years 1998, 2010 and 2022. Overall accuracy is determined from the confusion matrix, which ranges from 80% to 91%. Supervised classification yielded seven occupancy classes: water bodies, cultivated areas, gallery forests, habitats/outcrops, grassy savannahs, wooded savannahs and bare ground. Quantification of change from 1998 to 2022, assessed by the rate of change (Tc), shows a progressive trend estimated at 31.82% (habitats/outcrops) and 43.40% (grassy savannah), and a regressive trend estimated at -17.92% (cultivated areas); -95.15% (gallery forests); -51.93% (water bodies) and -78.36% (bare ground). At the end of our study, diachronic analysis enabled us to quantify changes between the years 1998-2010, 2010-2022 and overall 1998-2022 with good precision.

Introduction: An estimated 2.6 million still birth occur annually in the world in 2015. Nigeria then accounted for about 12.2% of this being the second highest still birth rate. Still birth is death of the fetus at or after 28 weeks of gestation. In some clime it is death of a fetus at or after 22 weeks. Aim: The study aim is to review still birth, determine the rate and characteristics of stillbirth at the Prince Abubakar Audu University teaching hospital, Anyigba, North Central Nigeria. Methods: This was a retrospective study conducted at Prince Abubakar Audu University Teaching Hospital in Anyigba, Nigeria between September and December 2023. We reviewed deliveries over a 5 year period; between January, 2018 and December 2022. A tool was used to extract data on pregnancies, live births, still births and other relevant related information about the parturients. Data was analyzed (descriptive analysis) using statistical package for social sciences (SPSS) version 20. Results: The institutional stillbirth rate is 3.8% (38 per 1000 deliveries). Majority of Women that had stillbirth were in the age range 21 to 39 years (82%), 29 (56.8%) booked while 18 (38.3%) were unbooked. 25(49%) were multiparae followed by 17 (33%) who were primigravidae and 9(18%) grand multiparae. 55 % (28) of the stillbirths were macerated at delivery while 45 % (23) were fresh still births. Preeclampsia/eclampsia (19.6%) was the most identified risk factor followed by prolonged obstructed labour (11.8%), ruptured uterus (9.8), PPROM (9.8%) and Preterm delivery (9.8%). The others are abruption placentae (5.9%), maternal infection (3.9%) and congenital abnormality (2%). Conclusion: The still birth rate of 38/1000 total births is unacceptably high leaving a lot of women with muted grief after childbirth. We need more effort to eliminate or reduce the incidence of still births.
