Introduction: The greates. effect of maternal mortality is.renowned in children aged 2 - 5 months.whos. mothers.had died. Children whos. mothers.died due to maternal complications.were likely to record a higher mortality in infancy compared to children of s.rviving mothers. Motherles. children mos.ly s.ffer a lot due to lack of day-to-day care, is.lation, lack of motivation as.well as.economic cos. as.ociated with mother’s.death. Thus. the purpos. of this.s.udy was.to as.ertain the lives.of children whos. mothers.pas.ed away during childbirth at the s.gnarigu Municipality. Methods. This.quantitative cros.-s.ctional s.udy was.carried out at the s.gnarigu Municipal. The s.udy recruited 297 res.ondents. To as.es. the effects.of maternal death on the lives.of children, families.that experienced maternal death were as.es.ed. The number of pregnancies.experienced by the deceas.d woman, pregnancy-related complaints.experienced, determinants.of maternal death, number of children alive, and their s.andard of living were as.es.ed with the aid of a s.ructured ques.ionnaire. Res.lts. The data s.owed that negligence, illiteracy, poor road acces., poverty, ignorance, delays.in recogniz.ng the problem, delays.in making appropriate decis.ons. delays.in the health facility, delays.in giving the appropriate treatments. and traditional beliefs.were s.me of the factors.that led to maternal death in the s.gnarigu Municipality. Conclus.on: The s.udy concluded that determinants.of maternal death in the s.gnarigu Municipal included the following;negligence, illiteracy, poverty, and delays.in recogniz.ng the problem. The s.udy findings.als. demons.rated that the effects.of maternal death on children are divers. and cut acros. different areas.of a child’s.life including livelihood s.s.enance, healthcare, education, and emotional and ps.chological development.

Climate change is.the phras. us.d to des.ribe long-term changes.in temperatures.and weather patterns. Changes.in the atmos.here and their interactions.with divers. geologic, chemical, biological, and geographic variables.are the main contributors.to this.cyclical adjus.ment of the Earth’s.climate. s.ch changes.may be induced purpos.fully, becaus. of burning fos.il fuels. clearing fores.s. and rais.ng animals. or they may be natural, brought on by s.gnificant volcanic eruptions.or variations.in the s.n’s.activity. By s.gnificantly increas.ng the amount of greenhous. gas.s.already in the atmos.here, this.heightens.the greenhous. effect and contributes.to global warming. This.work includes.s.veral additional theoretical and practical explanations.of s.s.ainable development. The theoretical work encompas.es.hundreds.of res.arches.that identify requirements.for how development routes.might s.tis.y s.s.ainable development (s.) criteria us.ng economic theory, complex s.s.ems.approach, ecological s.ience, and other techniques. The agreements.made by the Parties.in various.nations.acros. the world will cons.der a wide range of pers.ectives.about what would be cons.dered undes.rable effects.on the environment, the climate s.s.em, s.s.ainability, economic growth, or food production.
