The destructive impact of land degradation on social and economic endeavours of the residents of certain urban areas of Abeokuta communities in Ogun State, Nigeria calls for remedial actions to restoring the affected land areas. This becomes essential in order to ensure safe inhabitation and enhanced socioeconomic engagements of the residents. Taken remedial actions in this regard included the use of sandbags, debris and wood logs, rubbles and stones, construction of contours and drainages. While each of these actions, in one way or the other, effectively improves the degraded land, it was concluded that the use of rubbles and stones, and drainage construction were sustainably durable for land restoration on the premise that these actions does not allow for water logging or flooding in of the study area. It was however recommended that these sustainable remedial actions should rather be pro-actively taken for prevention of land degradation than being taken as degraded land restoration actions basically because it is much cheaper to prevent environmental degradation than to have the degraded land restored.

Destrukcyjny wpływ degradacji ziemi na socjalne i ekonomiczne przedsięwzięcia mieszkańców niektórych obszarów miejskich w Abeokuta w stanie Ogun w Nigerii wymaga podjęcia działań naprawczych w celu przywrócenia odpowiedniej jakości przekształconym obszarom. Jest to ważne ze względu na bezpieczeństwo i większe społeczno-ekonomiczne zaangażowanie mieszkańców. Działania naprawcze podjęte w tym zakresie obejmowały użycie worków z piaskiem, gruzu, kłód drewnianych i kamieni oraz tworzenie spadków i budowę drenaży. Choć każda z tych akcji w jakiś sposób wydajnie polepsza jakość zdegradowanej ziemi, stwierdzono, że użycie gruzu i kamieni oraz budowa konstrukcji drenarskich były odpowiednie do rekultywacji ziemi na tym obszarze, pod warunkiem że działania te nie doprowadzą do wysycenia ziemi wodą lub do zalania terenu. Zalecono jednak, aby działania naprawcze były raczej podejmowane w celu zapobiegania degradacji ziem niż ich rekultywacji, ponieważ dużo taniej jest zapobiegać degradacji niż rekultywować już zdegradowane tereny.
