“…However, the food reserves and food intake of the wealthier farmers in years of poor rainfall may have been underestimated because we were unable to quantify the extent to which households differed in their ability to store surplus production from one year to the next (Ncube et al 2009). The quantities of firewood collected (4.5 t/yr per household) were similar to estimates made in Mutanda, Zimbabwe (5.5 t/yr per household; Grundy et al 1993), and in Limpopo province, South Africa (4.5 t/yr per household; Twine et al 2003). Quantification based on semistructured questionnaires is a powerful tool, although it may suffer from bias and potential for incorrect recall leading to under-or overestimation (Nemarandwe and Richards 2002).…”

ABSTRACT. Common lands provide smallholder farmers in Africa with firewood, timber, and feed for livestock, and they are used to complement human diets through the collection of edible nontimber forest products (NTFPs). Farmers have developed coping mechanisms, which they deploy at times of climatic shocks. We aimed to analyze the importance of NTFPs in times of drought and to identify options that could increase the capacity to adapt to climate change. We used participatory techniques, livelihood analysis, observations, and measurements to quantify the use of NTFPs. Communities recognized NTFPs as a mechanism to cope with crop failure. We estimated that indigenous fruits contributed to approximately 20% of the energy intake of wealthier farmers and to approximately 40% of the energy intake of poor farmers in years of inadequate rainfall. Farmers needed to invest a considerable share of their time to collect wild fruits from deforested areas. They recognized that the effectiveness of NTFPs as an adaptation option had become threatened by severe deforestation and by illegal harvesting of fruits by urban traders. Farmers indicated the need to plan future land use to (1) intensify crop production, (2) cultivate trees for firewood, (3) keep orchards of indigenous fruit trees, and (4) improve the quality of grazing lands. Farmers were willing to cultivate trees and to organize communal conservation of indigenous fruits trees. Through participatory exercises, farmers elaborated maps, which were used during land use discussions. The process led to prioritization of pressing land use problems and identification of the support needed: fast-growing trees for firewood, inputs for crop production, knowledge on the cultivation of indigenous fruit trees, and clear regulations and compliance with rules for extraction of NTFPs. Important issues that remain to be addressed are best practices for regeneration and conservation, access rules and implementation, and the understanding and management of competing claims on the common lands. Well-managed communal resources can provide a strong tool to maintain and increase the rural communities' ability to cope with an increasingly variable climate.

“…Unlike in other African countries, the use of charcoal was not observed even in urban areas. The observed consumption rates are slightly lower than values previously reported for rural Zimbabwe (Grundy et al, 1993;Hemstock and Hall, 1995). Overall, the observed consumption rates support the proposal of Hall et al (1994) that consumption rates of about 1,000 kg cap −1 yr −1 (rural) and 500 kg cap −1 yr −1 (urban) provide a reasonable estimate for Africa.…”

Abstract. Biomass burning has important impacts on atmospheric chemistry and climate. Fires in tropical forests and savannas release large quantities of trace gases and particulate matter. Combustion of biofuels for cooking and heating constitutes a less spectacular but similarly widespread biomass burning activity. To provide the groundwork for a quantification of this source, we determined in rural Zimbabwe the emissions of CO 2 , CO, and NO from more than 100 domestic fires fueled by wood, agricultural residues, and dung. The results indicate that, compared to open savanna fires, emissions from domestic fires are shifted towards products of incomplete combustion. A tentative global analysis shows that the source strength of domestic biomass burning is on the order of 1500 Tg CO 2 -C yr −1 , 140 Tg CO-C yr −1 , and 2.5 Tg NO-N yr −1 . This represents contributions of about 7 to 20% to the global budget of these gases.

“…The trade in medicinal plants in South Africa was worth some US$60 million in 1998, and is thought to be considerably more today (Mander 1998;Mander and le Breton 2006). Large volumes of miombo wood are used in home and pen construction (Grundy et al 1993). The growing timber sector of Mozambique reached export value of US$65 million in 2005, representing 4% of the total national exports.…”
