Changes in miombo woodland structure under different land tenure and use systems in central Zambia

Abstract: Aim Population pressure and communal land ownership are often perceived as serious threats to forest conservation in savanna woodlands of central and southern Africa. I aimed at testing the hypothesis that the rate of miombo woodland recovery after clearing and re-growth structure are determined by land tenure and use. Location Miombo woodland under customary, leasehold, forest reserve and national park on ten permanent and temporary sites was studied in central Zambia. Two sites were in mature woodland and eight sites were in re-growth miombo ranging in age from 1 to 30 years. Methods I enumerated and measured girth at breast height (1.3 m above ground) of trees/stems in sixty-four 20 × 10 m plots in 1982, 1986 and 2000 at six sites and annually from 1990 to 2001 at four sites to determine stem density and status (live, dead or cut) and wood biomass. A total of 239 trees were cut, wood biomass measured and the data used to develop equations for estimating wood biomass on study plots. Distance between each study site and the nearest human settlement was estimated during each sampling period using aerial photographs, topographical maps and the global positioning system. Results Land tenure was responsible for significant differences in stem density, wood biomass and rate of biomass accumulation in re-growth following clearing of mature miombo woodland. Although stem density was highest on customary land, wood biomass and accumulation rate were lowest. The highest biomass was on plots in forest reserves, with intermediate values for leasehold and national park. Fire was responsible for tree mortality at all the study sites and its impact was highest at a site in a national park. Sites close to human settlements had the highest density of cut stems but this activity did not significantly reduce wood biomass. Rate of woodland recovery was higher on sites cleared in the 1970s than on sites cleared in the 1990s, irrespective of age of re-growth. The development of the first, second and third re-growths following successive woodland clearing in 1972, 1981 and 1990, respectively, was not significantly different, except for stem density which was highest in the second re-growth. Analysis of interactions between five land tenure and use factors (independent variables) and re-growth structure revealed that 52% (P=0.0000) of the variation in stem density was because of re-growth age and decade in which the woodland was cleared while distance to human settlements and age of re-growth explained 42% (P=0.0000) of the variation in wood biomass. Individually, distance to human settlements explained 25% (P=0.0000) of the variation in wood biomass accumulation rate. Conclusion The results supported the hypothesis that rate of miombo woodland recovery and structure were influenced by land tenure and use. However, analysis of interactions between factors revealed that use related factors (i.e. decade in which woodland was cleared and distance to human settlements) and re-growth related factors (age and type of re-growth) were more important than land tenure per se in explaining variation in miombo recovery. The conclusion from these results is that regulation of land use is more important than change in land tenure to the proper management of miombo woodland.

Cultural childbirth practices and beliefs in Zambia.

Abstract: Background. Zambia, one of the world's poorest countries, also has one of the highest maternal mortality rates in the world. Most pregnant women in Zambia (96%) attend antenatal care, while 53% deliver at home. This may be related to socio-economic and cultural factors, but cultural childbirth practices and beliefs in Zambia have been little documented. Aim. The aim of this study was to explore cultural childbirth practices and beliefs in Zambia as related by women accompanying labouring women to maternity units. These social support women were also interviewed about their views on providing companionship to labouring women. Methods. Thirty-six women accompanying labouring women to urban and rural maternity units in Zambia were interviewed A thematic guide with closed and open-ended questions was used. EPI INFO, an epidemiological statistical software package, was used to analyse the quantitative data; qualitative data were analysed using content analysis. Findings. Eighteen of the women considered themselves to be mbusas, or traditional birth assistants and the rest said that they followed labouring women to maternity units. Those who considered themselves traditional birth assistants advised childbearing women on appropriate cultural childbirth practices and assisted with deliveries at home. They also advised women on the use of traditional medicine, for example, to widen the birth canal and to precipitate labour. If something went wrong during labour, they relied on traditional beliefs and witchcraft to explain the mishap and expected the woman in labour to confess her purported ‘bad’ behaviour. Twelve of the women were in favour of providing support to labouring women in maternity units and learning about childbirth care from midwives. Conclusion. These social support women, including those who considered themselves as mbusas, lacked understanding of the causes of obstetric complications during childbirth, and had inadequate knowledge of the appropriate management of labour. Culturally-specific knowledge from this study should be used to guide policy-makers and health planners in the future development of safe motherhood initiatives in developing countries. Midwives have a unique opportunity to ensure that care given during childbirth is clinically safe and culturally sensitive.

Integrated vector management: The Zambian experience

Abstract: The Zambian Malaria Control Programme with the Roll Back Malaria (RBM) partners have developed the current National Malaria Strategic Plan (NMSP 2006–2011) which focuses on prevention based on the Integrated Vector Management (IVM) strategy. The introduction and implementation of an IVM strategy was planned in accordance with the World Health Organization (WHO) steps towards IVM implementation namely Introduction Phase, Consolidation Phase and Expansion Phase. IVM has created commitment for Legal and Regulatory policy review, monitoring, Research and a strong stewardship by the chemical suppliers. It has also leveraged additional resources, improved inter-sectoral collaboration, capacity building and enhanced community participation which facilitated a steady scaling up in coverage and utilisation of key preventive interventions. Thus, markedly reducing malaria incidence and case fatalities in the country. Zambia has successfully introduced, consolidated and expanded IVM activities. Resulting in increased coverage and utilization of interventions and markedly reducing malaria-related morbidity and mortality while ensuring a better protection of the environment.
