The study focuses on the Nakpadjouak Community Forest (NCF) in Tami (Togo, West Africa) which contributes to community forests sustainable management. It aims in (i) mapping forest ecosystems and analysing their dynamic and (ii) characterizing the floristic diversity of the NCF. The ecosystems were mapped and their dynamic was evaluated based on Google Earth images of 2014 and 2020. Floristic and forestry inventories were carried out using the transect technique in a sample of 20 plots of 50 m × 20 m. The NCF was made up mainly by wooded/shrub savannahs (95.37%) and croplands/fallow (4.63%) in 2014. These two land use types undergone changes over the 6 years prior to 2020. By 2020, the NCF had 3 land use types: wooded/shrub savannahs (77.59%), open forest/wooded savannahs (22.23%), and croplands/fallows (0.18%). A total of 89 plant species belonging to 70 genera and 28 families were recorded within the NCF. The dominant species are: Heteropogon contortus (L.) P.Beauv. and Combretum collinum Fresen. followed by Pteleopsissuberosa Engl. & Diels, Annona senegalensis Pers. The most common species are: Lannea acida A.Rich. s.l., A. senegalensis, Vitellaria paradoxa C.F.Gaertner subsp. paradoxa, C. collinum and Acacia dudgeonii Craib ex Holland. Due to its small area of just 40 hectares and its diverse plant life, this community forest of Savannahs Region is a significant biodiversity hotspot and warrants conservation efforts.展开更多

Based on a literature review and satellite images analysis using GIS and remote sensing, the study aims to ascertain the effects of anthropogenic threats on the forest coverage of the Savannahs’ Region between 1984 to 2020. The objective is to clarify the dynamics of land use in the region from 1984 to 2000 and from 2000 to 2020. The findings indicate a significant decline in forest coverage within the region from 1984 to 2020, a trend attributed to land use patterns. Dry forests in the Savannah region are largely converted to farmlands, housing, dry savannahs or agroforestry parks, leading to a steady reduction in forest areas.展开更多

文摘Scaling-up agroforestry area in various forms is a scientific path towards achieving various sustainable development goals(SDGs),especially improving livelihood,reducing poverty,conserving environment and biodiversity,and transforming climate change.In this study,the effort was made to investigate the land potentiality for agroforestry at the district level in Jharkhand State,India by applying geographic information system(GIS)modeling technology using climate(temperature and precipitation),topography(slope and elevation),ecology(percent tree cover and normalized difference vegetation index(NDVI)),and social economics(poverty rate and tribal dominance)factors.The results revealed that six districts of Jharkhand State had agroforestry potential greater than 60.00%.The highest agroforestry suitability was found in Simdega District(78.20%),followed by Pakur(76.25%),West Singhbhum(72.70%),Dumka(68.84%),Sahibganj(64.63%),and Godda(63.43%)districts.Additionally,we identified 513 out of 32,620 villages of Jharkhand State potentially suitable(agroforestry suitability≥80.00%)for agroforestry with the objective of life improvement among marginalized society.Under the outside forest area,8.58%of the total geographical land of Jharkhand State was wasteland,much of which was found suitable for agroforestry practices.The agroforestry setups in those wastelands can absorb 637 t carbon annually in long run and can provide direct economic benefits to the locals besides additional income for carbon emission reduction.This study concluded that Jharkhand State has plenty of high potential land for agroforestry,and adoption of agroforestry at the village level must be given high priority.This study could guide the nodal authorities to prepare appropriate strategies for scaling the tree cover in agroforestry systems in village-level landscape planning which needs policy attention and investment for achieving 9 out of the 17 SDGs.

文摘For plant populations to persist,seedling recruitment is essential,requiring seed germination,seedling survival and growth.Drought and grazing potentially reduce seedling recruitment via increased mortality and reduced growth.We studied these seederelated processes for two species indigenous to the Pamir Mountains of Xinjiang in northwestern China:Saussurea glacialis and Plantago lessingii.Seeds collected from Taxkorgan,Xinjiang,had a viability rate of 15.8%for S.glacialis but 100%for P.lessingii.Of the viable seeds,the highest germination rates were 62.9%for S.glacialis and 45.6%for P.lessingii.In a greenhouse experiment,we imposed a series of stressful conditions,involving a combination of simulated grazing and drought events.These had the most severe impact on younger seedlings.Modelling showed that 89%of S.glacialis mortality was due to early simulated grazing,whereas 80%of P.lessingii mortality was due to early simulated drought.Physiological differences could contribute to their differing resilience.S.glacialis may rely on water storage in leaves to survive drought events,but showed no shifts in biomass allocation that would improve grazing tolerance.P.lessingii appears more reliant on its root system to survive grazing,but the root reserves of younger plants could be insufficient to grow deeper in response to drought.After applying all mortality factors,17.7 seedlings/parent of P.lessingii survived,while only<0.1 seedlings/parent of S.glacialis survived,raising concerns for its capacity to persist in the Pamirs.Inherent genetic differences may underlie the two species’contrasting grazing and drought responses.Thus,differing conservation strategies are required for their utilization and protection.
文摘Nature is in peril.The Convention on Biological Diversity(CBD)as the largest multilateral treaty on the protection of global biodiversity must play a significantly expanded role in the next decade of biodiversity policy development and implementation if we wish to halt and reverse accelerating biodiversity losses.From the 22nd–24th of June 2021,nearly 400 on-site and online participants gathered at the FTA Scientific Conference in Kunming,China as part of the buildup to the 15th meeting(COP15)of the CBD.From the technical and plenary sessions,12 recommendations emerged to strengthen the capacity of the CBD and safeguard the planet's wildlife.Participants urge all stakeholders,particularly government actors in attendance at CBD COP15 in Kunming in October 2021,to heed the warnings of experts in attendance at the FTA Scientific Conference to accelerate and intensify efforts to conserve diverse lifeforms and maintain healthy ecosystems by incorporating these 12 recommendations into the post-2020 global biodiversity framework of the CBD.
文摘Since 2015, community forests have been promoted in Togo as an alternative to protect areas from degradation and as a means of contributing to forest landscape restoration. The study focuses on the Nakpadjouak Community Forest (NCF) in Tami (Togo, West Africa) which contributes to community forests sustainable management. It aims in (i) mapping forest ecosystems and analysing their dynamic and (ii) characterizing the floristic diversity of the NCF. The ecosystems were mapped and their dynamic was evaluated based on Google Earth images of 2014 and 2020. Floristic and forestry inventories were carried out using the transect technique in a sample of 20 plots of 50 m × 20 m. The NCF was made up mainly by wooded/shrub savannahs (95.37%) and croplands/fallow (4.63%) in 2014. These two land use types undergone changes over the 6 years prior to 2020. By 2020, the NCF had 3 land use types: wooded/shrub savannahs (77.59%), open forest/wooded savannahs (22.23%), and croplands/fallows (0.18%). A total of 89 plant species belonging to 70 genera and 28 families were recorded within the NCF. The dominant species are: Heteropogon contortus (L.) P.Beauv. and Combretum collinum Fresen. followed by Pteleopsissuberosa Engl. & Diels, Annona senegalensis Pers. The most common species are: Lannea acida A.Rich. s.l., A. senegalensis, Vitellaria paradoxa C.F.Gaertner subsp. paradoxa, C. collinum and Acacia dudgeonii Craib ex Holland. Due to its small area of just 40 hectares and its diverse plant life, this community forest of Savannahs Region is a significant biodiversity hotspot and warrants conservation efforts.
文摘This study focuses on the landscape dynamics of the savannahs’ region in the far north of Togo. Based on a literature review and satellite images analysis using GIS and remote sensing, the study aims to ascertain the effects of anthropogenic threats on the forest coverage of the Savannahs’ Region between 1984 to 2020. The objective is to clarify the dynamics of land use in the region from 1984 to 2000 and from 2000 to 2020. The findings indicate a significant decline in forest coverage within the region from 1984 to 2020, a trend attributed to land use patterns. Dry forests in the Savannah region are largely converted to farmlands, housing, dry savannahs or agroforestry parks, leading to a steady reduction in forest areas.

文摘Wild edible fungi(WEF),including mushrooms and truffles,comprise a natural source of nutritious and healthy food.The consumption of WEF began at least 18,700 years ago during the Stone Age.Current data from over 100 countries indicates the existence of more than 2,100 edible species,a figure that is continually growing,as vast regions and many cultures remain understudied.However,only around 30 species of WEF are grown commercially at a large-scale.WEF also play a key ecological role in the structure and functioning of natural ecosystems and have significantly contributed in shaping all life on the planet.Either as food,medicine or both,they are important for the survival,cultures,and economies of hundreds of ethnic groups around the globe.Over the last 15 years,there has been a noteworthy increase in the international trade of WEF,which is currently estimated at billions(USD)annually.In 2017,the WEF global trade,of either fresh or processed products,exceeded 1,230,000 tonnes.Due to their ecological,sociocultural and economic importance,the international WEF trade has a role to play in the post-pandemic recovery period.The main challenge of this period will be maintaining natural ecosystems while simultaneously improving human wellbeing.Critical elements of this challenge include ensuring food security,enhancing rural development,creating sustainable jobs,mitigating hunger,and slowing the loss of traditional knowledge generated over millennia.This review analyzes the ways in which sustainable use of WEF could contribute to achieving these goals.
文摘In the 21st century,global food systems cannot remain stuck in the past.Agriculture currently contributes about one fourth of global greenhouse gas emissions and about half of all nutrient wastes annually[1].As the number of humans on the planet continues to grow,the effects of climate change will worsen and ecosystems will continue to deteriorate.Innovation in today’s agricultural food production systems is therefore urgently needed to increase crop and animal outputs,enhance dietary diversity and improve human health while conserving environments and sustaining natural resources and cultures.
文摘When we think of forests we usually think of trees,plants and animals.But forests could not exist without fungi,which lie at the base of the biodiversity webs that support much of life on Earth.Most fungi live as branching,fusing networks of tubular cells known as mycelium which can make up between a third and a half of the living mass of soils.Globally,the total length of fungal mycelium in the top 10cm of soil is more than 450 quadrillion km:about half the width of our galaxy.These networks comprise an ancient life-support system that easily qualifies as one of the wonders of the living world.Despite that,fungi represent a meagre 0.2%of our global conservation priorities.

文摘Mycorrhizal and N-fixing root symbioses evolved at two points in the past when global CO_(2)was highest,consistent with the high demand these symbioses place on host C.Trees hosting both mycorrhiza and N-fixing bacteria are able to fix more atmospheric CO_(2)and grow at faster rates than non-symbiotic plants,or plants with only mycorrhiza.We argue that on the basis of this improved C capture,N-fixing trees act as C-pumps,sequestering C and locking it in biomass,thus,if properly managed,can contribute significantly towards the mitigation of rising CO_(2)levels.

文摘Free-living nitrogen fixation(FNF)is a ubiquitous phenomenon that plays a modest role in the(N)economy of an ecosystem.However,sampling difficulties,methodological constraints and environmental controls have presented challenges for predicting the actual rate of FNF.Therefore,a deeper understanding of the accuracy to design models that consider dynamics,heterogeneity,influences,and other limitations is needed.This review presents an overview of the biology and diversity of microorganisms related to FNF as well as various ecological controls that influence these microorganisms.We also discussed contributions of FNF to the N input of various ecosystems.Overall,previous research has shown that considerable spatiotemporal variability exists in microbial types at both biome and microbiome scales,resulting in significant variation in FNF.Beyond this,rate of FNF is controlled by certain factors,such oxygen and metal ion availability,source of energy and soil nutrients,temperature,and pH.Empirical evidence increasingly indicates a significant contribution of FNF to N inputs in natural,agricultural,and aquatic ecosystems.It is inferred from this review that for the expanded exploitation of biological nitrogen fixation(BNF),we must pay additional attention to FNF because it occupies a central role within the process.Finally,we propose a framework for the quantification of FNF alongside a suite of recommendations that would deepen our understanding of FNF.

文摘Agroforestry has many benefits suited to mountain agricultural systems.This paper seeks to understand and quantify the mitigation potential of multifunctional agroforestry systems,and the potential for increased tree cover in mountains.The potential of agroforestry approaches for protecting irrecoverable carbon in mountains providing alternative,sustainable,and biodiversity-friendly livelihood options for local mountain communities is explored.A substantial portion(29%)of global'irrecoverable carbon'is found in mountains,representing irreplaceable ecosystems,biodiversity,and globally significant ecosystem services,under unprecedented environmental and demographic pressures,and rapidly changing climatic conditions.This'premium'mountain carbon supports high levels of biodiversity,including many of the last remaining large mammal species on the planet.Increasing tree cover within agricultural landscapes in mountains can provide sustainable,biodiversity-friendly development options that support environmental and biodiversity conservation.Estimates of existing and decadal change of above-and below-ground biomass on agricultural land within mountainous regions are modeled based up IPCC Tier 1 estimates.Two scenarios are evaluated to estimate carbon sequestration potential of increasing tree cover on agricultural land:1)incremental change and 2)a systemic change to agroforestry.Estimates of above-and below ground biomass carbon were combined with the tree cover analysis to estimate the change in biomass.Global increases(0.5−0.7 PgC for incremental change;1.1−2.7 PgC for systematic change)highlight the mitigation potential within mountain agricultural systems.A 10%increase in tree cover on all agricultural land within mountain regions is estimated to sequester 3 PgC.
文摘Forests,trees,and agroforestry(FTA)are ecosystem hotspots.They exemplify the contributions of biodiversity to sustainable and resilient landscapes,green circular economy and to sustainable agriculture and food systems for healthy diets.However,most research on these topics have been performed separately and lack comparison.The International FTA-Kunming Conference'Forests,trees and agroforestry for diverse sustainable landscapes'22nd–24th June 2021,focused on these contributions,brought together scientists NGOs,and policy makers to further the understanding of tree diversity;provided a communication platform for scientists to share their research results;evaluated the role of tree diversity in agroecology and circular agriculture;assessed benefits of landscape restoration;and explored applied research in mountain ecosystems and food security.The goals were to gather evidence that ground the design of solutions that can contribute to the implementation of the post 2020 Global Biodiversity Framework and towards the UN Food Systems Summit,and the overall implementation of the SDGs.This paper summarizes the outcomes of the international FTA Conference in Kunming 2021 and points out the highlights of research involved in six major themes.

文摘Sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi.The global diversity of teleomorphic species in Ascomycota has not been estimated.This paper estimates the species number for sexual ascomycetes based on five different estimation approaches,viz.by numbers of described fungi,by fungus:substrate ratio,by ecological distribution,by meta-DNA barcoding or culture-independent studies and by previous estimates of species in Ascomycota.The assumptions were made with the currently most accepted,“2.2–3.8 million”species estimate and results of previous studies concluding that 90%of the described ascomycetes reproduce sexually.The Catalogue of Life,Species Fungorum and published research were used for data procurement.The average value of teleomorphic species in Ascomycota from all methods is 1.86 million,ranging from 1.37 to 2.56 million.However,only around 83,000 teleomorphic species have been described in Ascomycota and deposited in data repositories.The ratio between described teleomorphic ascomycetes to predicted teleomorphic ascomycetes is 1:22.Therefore,where are the undiscovered teleomorphic ascomycetes?The undescribed species are no doubt to be found in biodiversity hot spots,poorly-studied areas and species complexes.Other poorly studied niches include extremophiles,lichenicolous fungi,human pathogens,marine fungi,and fungicolous fungi.Undescribed species are present in unexamined collections in specimen repositories or incompletely described earlier spe-cies.Nomenclatural issues,such as the use of separate names for teleomorph and anamorphs,synonyms,conspecific names,illegitimate and invalid names also affect the number of described species.Interspecies introgression results in new species,while species numbers are reduced by extinctions.
