In Tanzania, the majority of the rural population still relies on fuelwood as their major source of cooking energy. The adaptation measures of small-scale farmers in response to increasing fuelwood scarcity play a key role in altering the course of nutrition insecurity, environmental degradation, and economic instability. This study delivers a classification of coping strategies that does not exist in the literature. Furthermore, it analyses the adaptation measures applied by small-scale farmers in the semi-arid region of Dodoma district in response to fuelwood scarcity. A comparison between two case study sites provides information on the choice of adaptation measures by households. Overall, 28 coping strategies from 24 studies are identified, then differentiated into preventive and acute measures that are arranged into eight clusters. The classification is then used as a codebook to identify applied coping strategies at two case study sites. In total, 23 adaptation measures, including two strategies not cited in the literature, were identified through 39 household interviews. This suggests that the majority of coping strategies applied are independently from regional and social conditions. The majority of the strategies applied at the case study sites and described in the literature are acute measures that do not tackle the underlying problem triggering forest degradation. It is observed that the adaptation measures across the case study sites are widely congruent, thus showing that acute strategies are not replaced by preventive strategies but rather co-exist.

About 3 billion people worldwide depend on fuelwood to meet their domestic energy needs. Almost 90% of the population in Sub-Saharan Africa use fuelwood-based forms of energy. However, its use is often unsustainable and is one driver of environmental degradation. In Tanzania, the majority of rural residents depend on fuelwood as their major source of cooking energy. The adaptation measures applied by small-scale farmers in response to fuelwood scarcity are typically unsustainable with regard to socioeconomic , environmental, and food security dimensions. This study applies a methodological framework that assesses the personally experienced impact of coping strategies by local stakeholders on sustainability criteria. This framework comprises (1) the selection of appropriate adaptation measures; (2) the identification of local sustainability criteria; and (3) the participatory impact and frequency assessments at two case study sites in the semi-arid region of Dodoma in central Tanzania. Overall, eight coping strategies from 23 measures applied in the region were selected and four sustainability criteria defined by local key informants were identified. The participatory impact and frequency assessment show that the strategies of "on-farm tree planting" and "use of improved cooking stoves" are rated as positive across all four sustainability criteria and are regularly applied by the farmers. Two of the eight strategies are clearly negative: "eat fewer meals" and "increase in walking distance to collect fuelwood." These measures are regularly and widely used by farmers, thus amplifying the negative rating. Overall, the experiences of farmers suggest that applied coping strategies have the greatest negative effect on the environmental condition and, on average, a rather positive effect on economic conditions. The results offer an approach for developing a reliable monitoring of how adaptation measures are applied in response to fuelwood scarcity and to achieve distinct values for benchmarking.

The next generation of respiratory protective masks is expected to have lower burden filters with increased protection for the Warfighter. A market survey was conducted to identify novel commercial filtration media with low-pressure drop and high efficiency. Performance requirements for the filtration media included a pressure drop of ≤5 mmH 2 O and a particulate filtration efficiency of high-efficiency particulate air (99.97%) or better. Three companies had products that met the performance criteria, and their representatives will be contacted for samples. Six companies had promising technologies, and their representatives will be contacted for more information. These novel aerosol filtration media and technologies will be characterized in-house to determine if they could be included in the next generation respirator.
