December 2016 POLICY BRIEF Using & restoring the Miombo woodlands: needs for an integrated and holistic approach in ecosystem management for long term sustainability Policy decisions made now about how to Socio-ecological relationships in Miombo develop the Miombo region of Africa will woodlands have far-reaching consequences for the Miombo Woodlands are the people living in this region and for the Julbernardia/Brachystegia dominated globe. There are currently conflicting woodlands that span 2.7 million km2 across viewpoints about the best way to ensure eight countries in southern and eastern development goals and human livelihoods Africa: Democratic Republic of Congo, in the region, while also fulfilling Angola, Zambia, Zimbabwe, Malawi, conservation ideals and sequestering Tanzania, Mozambique and partly South carbon. These decisions need to be Africa (Figure 1). They are characterized by grounded on solid understanding of the highly variable woody canopy cover –from socio-ecology of the system, sound scientific 40-80% (Frost 1996). The ecosystem has information on the rates and causes of land high plant species diversity and endemism, cover change, and they need to include key- and a rich avifauna, containing several players at all levels of governance - from global hotspots of biodiversity: the local, to national, to global. grassland/woodlands mosaics NW and NE The Miombo Network (MN) is an alliance of Zambia (Mwinilunga, Mporokoso) are just a scientists that aims to achieve effective and few. appropriate management policies and 76% of the energy used in the region is practices by providing science-based derived from the woodlands (Ryan et al., information through the use of field-based 2016); timber products are exported; food approaches, remote sensing and other from bushmeat (Fa, 2015), caterpillars geospatial information technology, as well (Chama, 2016), honey (Ribeiro et al., 2016), as the valorization of traditional-knowledge roots, and leaves are a key source of systems and new biotechnologies.

Concurrently, the intact natural Miombo woodlands are under increasing pressure to provide all the resources mentioned above – not only to the rural population, but also to the ever- increasing urban population via trade and businesses. This may result in degradation of the woodlands and deforestation, which in turn reduces the resources that may be extracted. We estimate that between 250,000 and 300,000 ha/year of Miombo are degraded and/or lost (Miombo Network Meeting, July 2016). Figure 1.

The main tree species decisions are being made without a proper in Miombo are clonal - which means they appreciation of the contribution of Miombo use root suckers to spread. This makes woodlands to national treasury. Miombo vegetation very resilient to above- ground disturbances like fire and wood harvesting (Syampungani et al., 2015, Gumbo, 2016), but very sensitive to land clearing activities like large-scale cultivation, because the trees do not mainly regenerate from seed. Miombo requires cyclic cutting of mature stands, silvicultural thinning and pruning in stand development stages towards maturity, through regular Figure 2. Cyclic clearing-cropping-fallow- use of resources by rural society and others, regrowth maintains diversity & to maintain plant diversity and productivity productivity of Miombo (Source: of the system. Growth rates in mature Geldenhuys, 2016). Miombo can be slow - 0.24cm/year (Amade et al., 2016)- but when disturbed through harvesting/wind-throw the resprouting “Conserving Miombo does not require stumps can have high regrowth rates - up to stopping human activities – just 1.4cm per year when properly managed managing them.” (Syampungani, 2010). This implies that sustainable utilisation of Miombo is Local, national, regional, and global possible (e.g. Figure 2; Geldenhuys, 2016) if interests in Miombo woodlands are not various utilization aspects are incorporated always aligned (see examples below), and in Miombo woodlands management. this is exacerbated by lack of inter-sector coordination in the Miombo woodlands “Fires are an important ecological management.

Frequent fires can country level.

Appropriate fire Long-term scenario planning suggests that regimes are contested, and depend on the urban population of Africa will double particular management goals. But in general by 2030 (Campbel, 2014). This is not likely fire frequency of every 3-4 years and of low to reduce the pressure on woodland intensity are key to maintain the woodlands resources, but it does provide flexibility in (Ribeiro et al., 2013). terms of land use planning. Research demonstrates that it is possible to design development plans in Miombo, which Governance issues optimize agricultural production, carbon The economic contributions of Miombo storage and conservation objectives (Estes woodlands are not adequately accounted in 2016), but this requires good research- national GDP's, which means that they are policy relationships, and solid governance not appropriately valued in development structures. plans.
