SRH programs can help improve the nutritional status of women and their children and advance progress on the hunger and maternal and child health targets. Supplemental feeding programs for pregnant women, improving wom- en’s knowledge of the nutritional requirements of themselves and their children and increasing women’s power to negotiate access to needed nutrition must be part of a multi-intervention strategy. Closely spaced pregnancies and the associated high fertility levels place women at an increased risk of anemia and other conditions of absolute and relative malnutrition. Progress in alleviating hunger also requires targeted inputs to improve agri- cultural productivity.

Not only are the rates of deforestation very high but also approximately 40 of the existing forest areas have been degraded in recent times. It is estimated that tropical rain forests will largely disappear in about 30 years time except for those that might be conserved as nature reserves. Obviously there is a need for greater investment in scientific research in ecology conservation and management of ưopical rain forests worldwide. There are three crucial interrelated issues that a manager of indigenous forests must address depletion of forest resources regeneration and restoration of forest ecosystems and conservation of genetic resources. The challenges generated by the reduction and degradation of forest cover can be adequately met only if serious attempts are made to manage and restore forest ecosystems. Restoration inevitably must involve improved reforestation of degraded lands through plantations of native species and the extension of forest boundaries by artificial and natural regeneration. Finally coupled with effective management including restoration conservation of
