Farmer Managed Natural Regeneration (FMNR) comprises a set of practices used by farmers to encourage the growth native trees on agricultural land. FMNR is reported deliver number positive impacts, including increasing productivity through soil fertility improvement and feed for livestock, incomes, other environmental benefits. It widely promoted in Africa as cost-effective way restoring degraded land, that overcomes challenge low survival rates associated with tree planting arid semi-arid areas. Despite being promoted, evidence these bold claims about has not been systematically analyzed. This paper reviews scientific related contexts which practiced across sub-Saharan Africa, how this influences composition regenerating vegetation, resulting socio-economic benefits derived from it. reveals quantitative outcomes sparse mainly experience Maradi Zinder regions Niger. There little mechanistic understanding relating context conditions diversity abundance turn ecosystem function livelihood makes it difficult determine where whom an appropriate restoration technique might be necessary combine enrichment planting. Given need viable land well beyond climatic edaphic covered existing studies, we recommend research combining functional ecology assessments, embedded co-learning components within scaling up initiatives. would fill key knowledge gaps, enabling development context-sensitive advice promote FMNR, calculation return investment doing so.

Leveraging the blue economy to transform marine forest restoration

Journal of Phycology, Journal Year: 2022, Volume and Issue: 58(2), P. 198 - 207

The UN Decade of Ecosystem Restoration is a response to the urgent need substantially accelerate and upscale ecological restoration secure Earth's sustainable future. Globally, commitments have focused overwhelmingly on terrestrial forests. In contrast, despite strong value proposition, efforts restore seaweed forests lag far behind other major ecosystems continue be dominated by small-scale, short-term academic experiments. However, forest can match scale damage threat if moved from academia into hands community groups, industry, practitioners. Connecting two rapidly growing sectors in Blue Economy-seaweed cultivation industry-can transform marine commercial-scale enterprise that make significant contribution global efforts.

Meta-analysis of global soil data identifies robust indicators for short-term changes in soil organic carbon stock following land use change

The Science of The Total Environment, Journal Year: 2022, Volume and Issue: 860, P. 160484 - 160484

The restoration of degraded lands and minimizing the degradation productive are at forefront many environmental land management schemes around world. A key indicator soil productivity is organic carbon (SOC), which influences provision most ecosystem services. major challenge in direct measurement changes SOC stock that it difficult to detect within a short timeframe relevant managers. In this study, we sought identify suitable early indicators their drivers. meta-analytical approach was used synthesize global data on impacts arable conversion other uses total stock, 12 different fractions three structural properties. forests grasslands accounted for 91 % available use change datasets meta-analysis were mostly from Asia Europe. Land led 50 (32–68 %) mean increase both labile (microbial biomass C particulate – POC) passive (microaggregate, 53–250 μm diameter; small macroaggregate, 250–2000 diameter) as well stability. There also 37 (24–50 experimental fields where various measured. Only POC stored macroaggregates had strong correlation with SOC: our findings reveal these two predominantly controlled by input rather than climatic factors thus candidate short-term stock. Further field studies recommended validate predictive power equations developed study metrics under scenarios.
