“…1), the microbiological attributes did not differ between seasons. This result is contrary to that expected due to the negative effects of lack of soil moisture on the However, Bae et al (2013) also found no correlation between BResp and soil moisture in agroforests as well as for natural regeneration. For these authors, the fact that the soil in these systems store more water, allowed the microorganisms to not suffer the effect of the absence of rain.…”

“…Concerning BResp, except in the 0-2.5 cm layer in which NR was higher than agroforestry and is attributed to the likely density of fine roots (Bae et al 2013) which stimulating the activity of the microbiota, the BResp of all treatments was similar in the other layers regardless of the size of the microbial biomass. This is an unexpected result, considering the difference in management of the agroforests, as in the case of AF5, that contributes green material on the soil surface, which could benefit the microbial activity.…”

“…The MB-C of the NR was higher than in the agroforests up to 10 cm, and may be a result of the root system. Bae et al (2013), working with agroforestry and a secondary forest in hot and dry weather, obtained a high relationship between fine root biomass and microbial biomass and soil basal respiration.…”

“…These processes can be altered by agricultural practices (Bae et al 2013;Moço et al 2009). Thus, the self-regulation of agroforestry depends on the plant composition, their distribution in time and space, and the management employed in the areas, especially pruning.…”

The aim of this study was to evaluate the biomass and activity of the microbiota and active soil fauna of agroforestry developed in the Atlantic Forest Biome.…”

The diversity of cultivated plants in the agroforestry systems can create conditions to maintain the vital edaphic processes similar to natural regeneration areas. We studied agroforestry systems with five (AF5) and ten years (AF10) of age in comparison with natural regeneration areas for 10 years (NR) in the Atlantic Forest Biome in an area of environmental fragility. The microbial biomass carbon (MB-C), soil basal respiration (BResp), metabolic quotient (q-CO 2 ) and microbial quotient (q-mic) were evaluated in the entire profile of a Typic Udorthents, obtaining stratified data in the 0-2.5; 2.5-5; 5-10; 10-15; 15-30; 30-45 and 45-60 cm layers. The NR area had the highest MB-C (866 mg C kg -1 soil) and BResp (5 mg C-CO 2 kg -1 soil h -1 ) in the 0-2.5 cm layer in relation to the AF5 (686 mg C kg -1 soil; 4 mg C-CO 2 kg -1 soil h -1 ) and AF10 (478 mg C kg -1 soil; 4 mg C-CO 2 kg -1 soil h -1 ). However, the ratios did not differ among treatments, presenting average values in the profile of 7 mg C-CO 2 g -1 MB-C h -1 for q-CO 2 and 1.6 % for q-mic, demonstrating vital process similarity between systems. The phytosociological characteristics that interfere with the microbiological attributes were the plant species richness (0-2.5 cm) and plant diversity (2.5-5 cm). The epiedaphic fauna active in the litter was also assessed by pitfall traps and the average number of individuals per trap (238 for NR, 281 for AF5, 299 for AF10), the order richness (15 for NR; 14 for AF5, 13 for AF10) and relative frequencies did not differ among treatments, confirming that agroforests are in an ecosystem self-regulation condition function similar to natural regeneration, even with the removal of food products and income generation for the farmers.

Declining agricultural productivity, land clearance and climate change are compounding the vulnerability of already marginal rural populations in West Africa. 'Farmer-Managed Natural Regeneration' (FMNR) is an approach to arable land restoration and reforestation that seeks to reconcile sustained food production, conservation of soils, and protection of biodiversity. It involves selecting and protecting the most vigorous stems regrowing from live stumps of felled trees, pruning off all other stems, and pollarding the chosen stems to grow into straight trunks. Despite widespread enthusiasm and application of FMNR by environmental management and development projects, to date, no research has provided a measure of the aggregate livelihood impact of community adoption of FMNR. This paper places FMNR in the context of other agroforestry initiatives, then seeks to quantify the value of livelihood outcomes of FMNR. We review published and unpublished evidence about the impacts of FMNR, and present a new case study that addresses gaps in the evidence-base. The case study focuses on a FMNR project in the district of Talensi in the semi-arid Upper East Region in Ghana. The case study employs a social return on investment analysis, which identifies proxy financial values for non-economic as well as economic benefits. The results demonstrate income and agricultural benefits, but also show that asset creation, increased consumption of wild resources, health improvements, and psycho-social benefits created more value in FMNR-adopting households during the period of the study than increases in income and agricultural yields.
