However, other suggested actions (e.g. increased use of treated effluents and the introduction of genetic improvements to crops and farm animals) could erode biodiversity. Likewise, adaptation actions taken in relation to coastal zone defence, such as specific forms of coastal infrastructure and the use of sea protection and sand nourishment techniques, could negatively impact biodiversity. Such trade-offs and concerns should be reflected in the final National Adaptation Plan. Most poverty reduction efforts are targeted at urban populations and are not necessarily related to agriculture or to natural resources.
