Contrasting land use systems influence soil seed bank composition and density in a rural landscape mosaic in West Africa

Posted by

FTA COMMUNICATIONS TEAM

Soil seed banks (SSBs) play a key role in the post-disturbance recruitment of many plant species. Seed bank diversity can be influenced by spatial and environmental variability and disturbance heterogeneity across the landscape. Understanding the recovery potential of native vegetation from SSBs is important for restoration and biodiversity conservation. Yet, in savanna-woodland, little is known about how SSBs vary in their germination, composition and density under different land uses, and how SSBs relate to aboveground vegetation (AGV). Using a sampling design based on the Land Degradation Surveillance Framework, we assessed the SSB and AGV in twelve 0.25?ha plots among sixteen in four contrasting land use systems of savanna-woodland in Burkina Faso: bushland, cultivated farmland, fallow and wetland. A total of 720 soil samples were taken from four stratified depths of 0–5?cm, >5–10?cm, >10–15?cm, and >15–20?cm. The SSB composition and richness was determined by the seedling emergence technique. Results showed that the SSB in all land uses was largely dominated by annual grasses with few perennial herbaceous and woody species. Seed density was highest in the fallow soil and highest in the upper soil layers for all land uses. A non-metric multidimensional scaling ordination of the SSB and AGV indicated that the SSBs were a poor reflection of the AGV. Based on these findings, spatial variations in landscape characteristics not only influence seed distribution and viability but also have the potential to influence population persistence. These results imply that successful restoration of fragmented ecosystems requires the addition of seeds and seedlings of target species.

  • Delivery of quality and diverse planting material

Delivery of quality and diverse planting material

Posted by

FTA COMMUNICATIONS TEAM

Delivery of quality and diverse planting material is a major constraint for restoration. What solutions, what emerging needs? The Bonn Challenge has now pledged 350 million hectares of degraded land globally for different forms of restoration. It can be an essential contribution to sustainable development, to reduce poverty, food insecurity and enhance biodiversity. However, restoration is easier pledged than done. A critical barrier to delivering restoration at scale is the lack of delivery systems at scale for diverse, adapted and high quality native tree seeds and planting material.

This discussion forum will bring together representatives from national governments who have made significant pledges under the Bonn Challenge, development actors, private sector (seed and planting material companies), civil society, and researchers from the CGIAR Research Program on Forests, Trees and Agroforestry. It will show the extent of the challenge, review and discuss the range of issues related to the set-up at scale of delivery systems of suitable and adapted seeds and planting material, for effective, sustainable land restoration. It will explore the practical technical, economic and institutional challenges stakeholders currently face in delivering at scale suitable seeds and planting material. It will also explore issues such as how to best access and leverage tree biodiversity, including native species, keeping into account the quality, origin and diversity of seeds and planting material used. It will present and discuss a range of technical, economic and institutional solutions that scientists and stakeholders have developed to address these issues. Participants will discuss the common solutions across regions and remaining gaps and barriers, as well as the need for additional innovations.

  • Fine-scale processes shape ecosystem service provision by an Amazonian hyperdominant tree species

Fine-scale processes shape ecosystem service provision by an Amazonian hyperdominant tree species

Posted by

FTA COMMUNICATIONS TEAM

Conspecific distance and density-dependence is a key driver of tree diversity in natural forests, but the extent to which this process may influence ecosystem service provision is largely unknown. Drawing on a dataset of >135,000 trees from the Peruvian Amazon, we assessed its manifestation in biomass accumulation and seed production of Brazil nut (Bertholletia excelsa) which plays a keystone role in carbon sequestration and NTFP harvesting in Amazonia. For the first time, we find both negative and positive effects of conspecific proximity on seed production and above ground biomass at small and large nearest neighbour distances, respectively. Plausible explanations for negative effects at small distances are fine-scale genetic structuring and competition for shared resources, whereas positive effects at large distances are likely due to increasing pollen limitation and suboptimal growth conditions. Finally, findings suggest that most field plots in Amazonia used for estimating carbon storage are too small to account for distance and density-dependent effects and hence may be inadequate for measuring species-centric ecosystem services.

  • Genetic diversity of Ceiba pentandra in Colombian seasonally dry tropical forest: implications for conservation and management

Genetic diversity of Ceiba pentandra in Colombian seasonally dry tropical forest: implications for conservation and management

Posted by

FTA COMMUNICATIONS TEAM

Seasonally dry tropical forests (SDTFs) are one of the most degraded vegetation types worldwide and in Colombia<10% of the original cover remains. This calls for urgent conservation measures and restoration efforts. Understanding the genetic diversity and structure of tree species is crucial to inform not only conservation measures, but also sourcing of planting materials to ensure the long-term success of tree planting efforts, particularly in light of climate change. We assessed the genetic diversity distribution and structure of Ceiba pentandra from twelve representative locations of SDTF in Colombia, and how they may have been shaped by past climatic changes and human influence. We found three different genetic groups which may be the result of differentiation due to isolation of the Caribbean region, the Upper Cauca River Valley and the Patía River Valley in pre-glacial times. Range expansion of SDTF during the last glacial period, followed by more recent range contraction during the Holocene can explain the current distribution and mixture of genetic groups across contemporary STDF fragments. Most of the sampled localities showed heterozygosity scores close to Hardy–Weinberg expectations. Only two sites, among which the Patía River valley, an area with high conservation value, displayed significantly positive values of inbreeding coefficient, potentially affecting their survival and use as seed sources. While the effects of climate change might threaten C. pentandra populations across their current distribution ranges, opportunities remain for the in situ persistence of the most genetically diverse and unique ones. Based on our findings we identify priority areas for the in situ conservation of C. pentandra in Colombian SDTF and propose a pragmatic approach to guide the selection of appropriate planting material for use in restoration.

Around 12 percent (two billion hectares) of the Earth’s land surface is degraded. Degraded lands cost 10% of global GDP annually. The potential societal benefits of restoring degraded land is in the order of US$84 billion per year. Restoration of degraded tropical forest landscapes offer some of the greatest returns on investment, to address climate change, reduce poverty and food insecurity and support biodiversity.

To deliver sustainable development goals (SDGs) optimal restoration approaches are vital and the link between knowledge of native tree diversity and appropriate use to address SDGs in currently lacking. This represents a significant gap in capacity to enable scaling up FLR pledges from the Bonn Challenges to deliver multiple SDGs through restoration of degraded lands.

FTA COMMUNICATIONS TEAM

The CGIAR Research Program on Forests, Trees and Agroforestry (FTA) contributes to 9 Sustainable Development Goals (SDGs), to all CGIAR Intermediate Development Outcomes (IDOs) and to 31 sub-IDOs with different levels of investment. With efforts targeted respectively at 29%, 33%, 38% across System Level Outcomes (SLOs) 1, 2 and 3, FTA balanced its work across four main production systems (natural forests, plantations, pastures and cropping systems with trees) dealing with a number of globally traded and/or locally important tree-crop commodities (timber, oil palm, rubber, coffee, cocoa, coconut, wood fuel, fruits, etc.), that form the basis for the livelihoods of hundreds of millions of smallholders. These commodities also represent an important share of the land area, including 13 million km2 of forests and 9.5 million km2 of agricultural lands (45% of the total agricultural area with >10% tree cover). Progress towards IDOs in 2017 resulted from FTA work on technical innovations and tools, as well as on value chains, and institutional and policy processes. These innovations were taken up and diffused by different actors and along value chains, and all were suited to their particular context. As 2017 is the first year of FTA’s six-year program, progress towards SLOs was aimed at the upstream level; in some cases there was already progress towards downstream uptake.

The second of three Global Landscapes Forum (GLF) in 2018 is being held at the UN headquarters in Nairobi, Kenya, on Aug. 29 to 30, with a focus on forest and landscape restoration.

The World Agroforestry Centre (ICRAF), one of the CGIAR Research Program on Forests, Trees and Agroforestry’s (FTA) partner institutions, is based in Nairobi, and its Director General Tony Simons is set to have some of the last words at this current GLF.

Simons is speaking in the Policy Plenary just before the conference finale, which will explore how to create enabling environments for transformational change in landscape management in the region.

Originally from New Zealand, Simons has an impressive track record working on issues at the interface of tropical agriculture and forestry in more than 40 developing countries. GLF’s Landscape News spoke with him about the potential he sees for policy change to help make forest landscape restoration work for ecosystems, people and profit across the African continent.

What are some of the issues for enabling sustainable landscapes in Africa at the moment?

Africa has tremendous opportunities, but it’s also got a lot of issues and difficulties. It’s the second largest continent in the world; the second most highly populated; the most rural; the poorest; and the most reliant on agriculture. It has the least forest cover; the highest use of wood energy; and it’s got one of the youngest populations in the world. There are very low levels of mechanization in agriculture: 95 percent of crops are rain-fed, and only 5 percent are irrigated.

Staggeringly, Africa imports 35 billion dollars a year of food. That’s going to be 110 billion by the year 2030. Of that 35 billion, 95 percent of that is brought in from other continents. So while there is plenty of land available – and people to work it – food production is not yet happening at the scale that it should be.

What policies need to change to help make landscapes more sustainable?

Back in 2009, the African Union [AU] heads of state passed a resolution on land use and management across the continent. It was at a time where there was a huge amount of attention on land grabbing. So the policy instruments put into place were about keeping the resource under sovereign control.

So that’s one of the issues in Africa now: about 75 percent of the land – even if it’s under customary control – is formally owned by the government. And the governments don’t really know what to do with it.

I think we’ve got to put land stewardship back in the hands of people. You’ve got the land; you’ve got a young population; you’ve got growing prosperity; better education; literacy and numeracy is growing; but there needs to be a kind of revolution in land management. It’s not going to be by individuals; it’s going to be by groups, collectives, communities and watersheds. We’ve got to leverage the agenda of that wise stewardship down to the level of the people.

Sustainable management costs money. How can we make it worth people’s while?

If you travelled to the world’s second largest rainforest, which is the Congo, and I sold you an acre of rainforest, it would cost about $10,000. But the government gets less than $100 of revenue from that per year: a 1 percent return. That’s the biggest problem with forests and wetlands: they’re not remunerative.

And that’s because we don’t count the value of all of the fantastic biodiversity, carbon provisioning, precipitation enhancement and other ecosystem services that these places provide. In a continent where 95 percent of crops are rainfed, forests are very important for agriculture. But protecting and restoring them is not remunerative because of the partial accounting. So that needs to change.

However, we’re not going to get anywhere if we spend all this money restoring the land to how it was in the past, because it will still be under pressure for exploitation. So we’ve got to make a viable business case for restoring that land. And that’s going to be about connecting and linking financial capital, natural capital, human capital and social capital.

This is also at a time when we’re seeing pressures on financing. So how do we get all of these new approaches and opportunities out to people? NGOs (non-governmental organizations) have stepped up in quite a large way, but the private sector needs to step up much more. And for that to happen, there are a number of things that we need to look at. The first one is the opportunities: where are the business cases, the viable enterprises to piggyback on?

The second thing to look at is investment return. What returns will the governments, the small-scale farmer, the community and the foreign investor get from investing in landscape restoration? And what are the risks associated with this, and how can we de-risk? Many people perceive agriculture as complicated, as confused, as risky, as having a low rate of return, as not really investment material. Investors need to see that yes, this is a viable enterprise, and when we start thinking about bringing that financial return to social dividends, to environmental dividends, that’s when it all starts to come together.

Beyond opportunity, risk and return, next comes leverage. We have been relying in Africa on external Overseas Development Assistance (ODA); but ODA is currently drying up and being reallocated. Now for every single dollar of ODA, there’s $3 of remittances, there’s $6 of Foreign Direct Investment (FDI), there’s $24 of domestic private sector spend, there’s $55 of national government spend, and there’s $1,000 of private capital.

So let’s use that $1 of ODA to leverage all those other sources. That’s going to be the real opportunity to bring change in landscapes.

What’s significant about having the GLF in Nairobi this year? 

Africa is innovative and unique. Practitioners can take things that worked in Latin America and Asia and adapt them, but Africa also has some fantastic indigenous ways of understanding and transforming landscapes. For example, we’re already seeing in Ethiopia how social capital is driving land use change.

The GLF provides an important opportunity to showcase that it’s not just doom and gloom, and that things are progressing. Let’s make a business case for restoration. Let’s connect with people; let’s think about gender, land ownership and tenure, and about motivating the youth. We candrive confidence to investors to bring financing to restoration. It’s not just about ecosystem services; it’s all of humanity that stands to benefit from this.

To hear more from Tony Simons and other policy experts, tune into the Policy Plenary live stream on Thursday, Aug. 30, at 5.45pm Nairobi time (GMT+3).

A global strategy for the conservation and use of coconut genetic resources 2018-2028

Posted by

FTA COMMUNICATIONS TEAM

This strategy came from extensive worldwide consultations, with support from Bioversity International, Agricultural Research Center for International Development (CIRAD), the CGIAR Research Program on Forests, Trees and Agroforestry (FTA) and ACIAR/DFAT, and outlines the means to conserve/use as much representative diversity as possible. More than 100 million people living in fragile coastal areas depend on coconut for their livelihoods. Globally, the demand for coconut products is expanding and offers new opportunities for increasing incomes for millions of small-scale coconut producers. At a time when the demand for coconut and coconut products is growing worldwide, it is important to conserve and utilize the rich biological diversity of the crop. This evolving Strategy will provide the benchmark for effectively implementing the comprehensive conservation and research agenda proposed by the international coconut research community, as a route to the enhanced wellbeing of millions of coconut smallholders across the globe.

  • Mapping conservation priorities for Asian tree species

Mapping conservation priorities for Asian tree species

Posted by

FTA COMMUNICATIONS TEAM

A new regional initiative is providing practitioners with tools for deciding where to focus conservation and restoration efforts.

The challenge: valuable tree species are under threat

Unsustainable extraction, along with changes in land uses and the climate, is threatening thousands of socioeconomically valuable tree species across Asia. These species urgently need conservation and restoration to help meet future needs for food, fuel and fiber in the world’s most populous region.

Yet, very little information is available about their historical and current distribution, patterns of genetic diversity, intensity of threats across their distribution ranges, or availability of seed sources to support restoration. Effective conservation strategies for these species and their genetic resources cannot be implemented without improving knowledge on the species’ distributions and the threats they are facing.

The solution: fill the knowledge gap

A new regional initiative is setting out to fill these gaps by producing up-to-date information on the distributions of valuable tree species and the threats to them, and guidance to develop conservation strategies that help maintain the genetic diversity and adaptive capacity of the species.

The Geographic Information for Conserving Native Tree Species and Their Genetic Resources in Asia-Pacific (APFORGIS) initiative is being coordinated by Bioversity International and implemented in collaboration with the Asia Pacific Forest Genetic Resources Programme (APFORGEN). The initiative contributes directly to APFORGEN’s new strategy for 2018-2022, which has named improving the availability and accessibility of species information as one of the network’s key objectives for the next five years.

50 pilot tree species

Tree species experts from across the region have identified 50 pilot species for APFORGIS, based on existing national priority species lists, socioeconomic importance and conservation status, and the diversity of species traits such as pollen and seed dispersal patterns, including:

  • Kokum (Clusiaceae: Garcinia indica), widely used for its edible fruits, seed oil and medicinal values, and an important source of income for rural communities, but rapidly declining in the wild.
  • Gamboge species which are dioecious (having separate male and female trees) – conservation guidelines need to consider sex ratios and larger than usual population sizes to avoid inbreeding.
  • Borneo Ironwood (Lauraceae: Eusideroxylon zwageri), as its name suggests, is one of the most durable and heaviest timber species in the world, used for centuries for building ships, docks and houses fit for humid tropical conditions. Ironwood grows very slowly and its seed are dispersed mainly by gravity in the vicinity of the mother trees, making the species vulnerable for genetic erosion. Many anecdotes about the iconic species’ decline exist, yet it does not have an accurate conservation status or specific conservation strategies in place.

Methods, tools and capacities developed for these and other species can be used by forest departments, research institutions and conservation organizations for other species of interest with similar characteristics.

Knowledge to inform conservation strategies

“Current lack of knowledge about these and other pilot species illustrates the conservation challenges in the vast and extremely diverse Asian region,” says Riina Jalonen, who is coordinating the initiative.

“Thirty-seven percent of the pilot species have never been assessed for their conservation status despite of their socioeconomic importance, and another 31 percent were last assessed in the 1990s. Of the species assessed in the past 10 years, three-quarters are threatened.”

APFORGIS uses existing information about the species occurrences and threats to them to develop species distribution models. The models give an estimate of historical, current and potential future distributions. The resulting maps will be validated by experts and used for identifying conservation priorities. They can also be used to design and target field studies in the future.

Regional species distribution and threat maps developed by APFORGIS will help to:

  • Identify centers of species diversity to optimize conservation efforts
  • Assess how well the current protected areas cover the priority areas for conservation
  • Identify areas where species populations may be most threatened by climate change
  • Identify seed transfer zones and adequacy of existing seed sources for tree planting and forest restoration
  • Plan studies on genetic diversity and provenance trials that are representative of the species’ range and the variation in environmental conditions

What’s next?

Based on up-to-date information about the species distributions and threats to them, the project will then develop guidelines for conservation units that maintain genetic diversity vital for the species survival, productivity and adaptive capacity. The units can also serve as sources of diverse and suitably adapted planting material, urgently needed for improving the success of forest restoration efforts.

Regional collaboration will allow countries share information and responsibilities in establishing and managing genetic conservation units. Fewer units are likely needed than if every country set up its own network, which helps to focus and sustain efforts over time.

The pilot species comprise:

  • Afzelia xylocarpa 
  • Ailanthus excelsa 
  • Albizia lebbeck 
  • Anisoptera costata 
  • Aquilaria crassna 
  • Aquilaria malaccensis

  • Intsia bijuga 
  • Intsia palembanica 
  • Koompassia malaccensis 
  • Myristica malabarica 
  • Neolamarckia cadamba 
  • Parkia speciosa 
  • Pericopsis mooniana 
  • Phyllanthus emblica 
  • Pinus kesiya  
  • Pinus merkusii 
  • Podocarpus neriifolius 
  • Pometia pinnata 
  • Pongamia pinnata
  • Pterocarpus indicus 
  • Pterocarpus macrocarpus 
  • Santalum album 
  • Scaphium macropodum  
  • Shorea leprosula 
  • Shorea macrophylla 
  • Shorea ovalis 
  • Shorea parvifolia 
  • Shorea pinanga 
  • Shorea roxburghii 
  • Sindora siamensis 
  • Tectona grandis 
  • Terminalia chebula 
  • Vatica mangachapoi 
  • Xylia xylocarpa

To achieve conservation for the valuable tree species and their genetic diversity across Asia, the initiative needs help to gather information on the species’ known distributions, whether current or historical.

  • Genetic Diversity Analysis Reveals Genetic Differentiation and Strong Population Structure in Calotropis Plants

Genetic Diversity Analysis Reveals Genetic Differentiation and Strong Population Structure in Calotropis Plants

Posted by

FTA COMMUNICATIONS TEAM

The genus Calotropis (Asclepiadaceae) is comprised of two species, C. gigantea and C. procera, which both show significant economic potential for use of their seed fibers in the textile industry, and of their bioactive compounds as new medicinal resources. The available wild-sourced germplasm contains limited genetic information that restricts further germplasm exploration for the purposes of domestication. We here developed twenty novel EST-SSR markers and applied them to assess genetic diversity, population structure and differentiation within Calotropis. The polymorphic information index of these markers ranged from 0.102 to 0.800; indicating that they are highly informative. Moderate genetic diversity was revealed in both species, with no difference between species in the amount of genetic diversity. Population structure analysis suggested five main genetic groups (K = 5) and relatively high genetic differentiation (FST = 0.528) between the two species. Mantel test analysis showed strong correlation between geographical and genetic distance in C. procera (r = 0.875, p = 0.020) while C. gigantea showed no such correlation (r = 0.390, p = 0.210). This study provides novel insights into the genetic diversity and population structure of Calotropis, which will promote further resource utilization and the development of genetic improvement strategies for Calotropis.

This paper is the seventh in the Fungal Diversity Notes series, where 131 taxa accommodated in 28 families are mainly described from Rosa (Rosaceae) and a few other hosts. Novel fungal taxa are described in the present study, including 17 new genera, 93 new species, four combinations, a sexual record for a species and new host records for 16 species. Some are introduced as new ascomycete genera. We also introduce new species. New host records are provided for others. New combinations are noted. This study also provides some insights into the diversity of fungi on Rosa species and especially those on Rosa spines that resulted in the characterization of eight new genera, 45 new species, and nine new host records. We also collected taxa from Rosa stems and there was 31% (20/65) overlap with taxa found on stems with that on spines. Because of the limited and non-targeted sampling for comparison with collections from spines and stems of the same host and location, it is not possible to say that the fungi on spines of Rosa differ from those on stems. The study however, does illustrate how spines are interesting substrates with high fungal biodiversity. This may be because of their hard structure resulting in slow decay and hence are suitable substrates leading to fungal colonization. All data presented herein are based on morphological examination of specimens, coupled with phylogenetic sequence data to better integrate taxa into appropriate taxonomic ranks and infer their evolutionary relationships.

• Forest restoration projects can derive great benefit from integrating climate modeling, functional trait analysis and genetic considerations in the selection of appropriate tree species and sources of forest reproductive material, for their critical importance for the delivery of ecosystem services and the viability and adaptive capacity of restored forests;
• Targets in restoration projects are not only quantitative but also qualitative. There is need for political commitment to create demand for good quality forest reproductive material of native species through regulatory frameworks and resource allocations;
• User friendly knowledge-based decision making tools need to be developed and mainstreamed to assist emerging restoration practitioners with the choice of tree species and sources of forest reproductive material;
• Countries need to increase experimental field setups such as provenance and progeny trials for native species to validate decision tools and apply adaptive management under climate change.
