Northwestern Vietnam is home to the three poorest provinces of the country, with a combined population of 3.4 million people and poverty ranging from 32% to 48% of households  across provinces.  There is a culturally diverse mix of communities comprising 30 ethnic groups but land use is dominated by maize production, largely sold for use as pig feed, on recently deforested slopes that are subject to high degradation rates.

In Son La province, for example, 65 000 ha of natural forest was converted to commercial maize cultivation between 2002 and 2009. In some areas shifting cultivation of upland rice, maize, soybean and cassava is still practiced but population pressures are shortening natural fallow periods, resulting in continuous cultivation with very little attention to erosion control measures exacerbating high economic and environmental risks.

Discounted cash flow (cumulative Net Present Value of agroforestry practices over a maize monoculture) calculated using production data from trials supplemented by information from mature trees and a 10% discount rate.

Most agricultural crops are grown as  monocultures on steep slopes, subject to soil degradation and declining crop yields. It is estimated from soil erosion measurements in farm trials, that typical erosion rates under maize monoculture in Yen Son district were almost 70 t ha-1 yr-1.

Agroforestry practices, involving contour planting of high value fruit and timber trees are a potential option for halting and reversing land degradation, improving ecosystem functions and enhancing the profitability of farming systems.

At the inception of the research reported here, agroforestry did not feature as an option in government policy at provincial or district level, and practical options for integrating trees on farms were not well developed in the region. There were only a few tree nurseries, generally producing germplasm of uncertain quality for a very narrow range of tree species. Farmers were further disadvantaged by low prices for products as a result of poor market access resulting from lack of infrastructure and market information, low and uncertain product quality along value-chains and lack of market links that affected the poorest disproportionately, leaving few livelihood options but subsistence agriculture.

Recognizing the potential of agroforestry, the World Agroforestry Centre (ICRAF) in Vietnam, with support from the Australian Centre for International Agricultural Research (ACIAR) and CGIAR research programme on Forests, Trees and Agroforestry implemented a comprehensive 5 year (2011 – 2016) agroforestry research project with local partners to improve the performance of smallholder farming systems in Northwestern Vietnam.

 “We sought to increase the productivity of associated crop and livestock systems, leading to more diverse and sustainable production systems and better income from tree products.” Says Delia Catacutan, Head of the ICRAF Office in Vietnam. “The project took advantage of recent improvements in infrastructure which facilitate market access and increased livelihood opportunities.”

The project titled: ‘Agroforestry for livelihoods of smallholder farmers in Northwest Viet Nam (AFLi) had four specific and interconnected objectives. The first was to develop viable agroforestry practices for three altitudinal zones (<600 m.a.s.l., 600-800 m.a.s.l. and >800 m.a.s.l.), involving active engagement of local people in the design and testing of agroforestry options through on-farm trials.

The second was to improve the availability of high-quality germplasm to enable the expansion of agroforestry, addressing issues of germplasm availability, quality and multiplication. The third objective was to enhance market access and opportunities for adding value to agroforestry products and the fourth was to facilitate policy dialogues and develop extension methods for widescale promotion of agroforestry across the region.

The main assumption underpinning and being tested in this work was that integration of well-chosen tree species into the farming systems and landscapes of Northwestern Vietnam will make production systems more profitable, environmentally sustainable and resilient.

“We built on existing agroforesty knowledge and ongoing research in North-West Vietnam, and put a strong emphasis on understanding the interactions between trees and livelihoods under different agro-ecological and socio-economic conditions in order to facilitate subsequent dissemination and adoption of agroforestry practices.” Says Dr La Nguyen, Project Leader of AFLi.

The project benefited from FTA’s global network of agroforestry research, specifically through introduction of successful sloping agricultural land technology from the Philippines and research on market development for agroforestry products and extension approaches from Indonesia and Cameroon.

FTA funds also enabled the project to respond both to farmer needs (through adding more diverse, multistrata practices to the range of options being evaluated) and opportunities to engage policy makers (through co-investment with provincial Departments of Agriculture and Rural Development (DARDs) to initiate a network of exemplar landscapes that showcase landscape transformation when agroforestry practices are adopted at scale in a given area).

This complementarity of flexible funds from FTA alongside the programmatic funding from ACIAR was important in ensuring that the research was locally relevant and that outputs were taken up at national and provincial levels.

At the end of the project in 2016, AFLi reported significant outcomes ranging from capacity strengthening, to economic, social and environmental benefits across the farming systems of Northwestern Vietnam.

Capacity outcomes: awareness, knowledge and skills. A key indicator measured against AFLi’s four project objectives is improving farmers’ awareness, knowledge and skills on establishing and managing agroforestry practices, including seedling/germplasm production and marketing. The project trained a significant number of stakeholders (lead farmers, extension staff and researchers) and raised awareness amongst key policy makers, who now provide a critical mass of expertise that can promote agroforestry practices across the region.

More than 2,000 people including farmers, extension workers and research partners were trained on different aspects of agroforestry including agroforestry design, tree pruning, seed and seedling production, and contouring. The introduction of farmer innovations from the Philippines including the pragmatic ‘ox back method’ for laying out contours rather than more cumbersome use of ‘A’ frames and the incorporation of cash crops in vegetation strips designed primarily to control erosion, were particularly valued by farmers.

A monitoring and evaluation survey showed that 73% of farmers in areas where training had been conducted knew the key elements required to implement agroforestry on farms, and were provided with adequate technical support from extension workers to establish agroforestry practices on their farms. The demonstration from the participatory farmer trials that agroforestry practices were a viable option in the region has raised awareness amongst policy makers leading to policy change at provincial and district levels (these are catalogued below), promoting and providing incentives for farmers to adopt agroforestry.

Through the development of a network of exemplar landscapes across the region in conjunction with provincial DARDs, it is anticipated that these trained farmers, research and extension staff will provide a critical nucleus of expertise to underpin widespread promotion of agroforestry – a strategy endorsed through ACIAR funding of a second phase AFLi project with a 60% higher budget than the first phase.

Economic outcomes: income and productivity.  Seven agroforestry options involving different combinations of fruit and timber trees with grass strips and maize were evaluated through participatory on farm trials over 3-4 years indicating higher productivity and profitability compared to maize monoculture. With most practices, net cashflow compared to maize monoculture was initially negative with investment costs greater than immediate returns, becoming positive after five years and then predicted to rise sharply (Figure 1).

For example, with longan-maize-forage intercropping, forage grass was the main income source in the first year, while income from maize started to pick up in the second year, and longan trees started to bear fruits in the third year and produce substantial yields from year five. Average annual incomes from the different agroforestry practices by their third year ranged from 16 to 38 million VND (700 – 1650 USD) ha-1 compared to an average of 12.5 million VND (544 USD) ha-1 for maize monoculture. There is also reduction in soil loss from agroforestry that could be valued at 5.7 million VND (250 USD) ha-1 which is the cost of replacing the NPK lost through erosion by purchasing fertilizer.

Discounted cash flow (cumulative Net Present Value of agroforestry practices over a maize monoculture) calculated using production data from trials supplemented by information from mature trees and a 10% discount rate.

The trials show the potential for agroforestry to substantially increase household income in the medium term but also indicate that farmers, particularly those in cash-poor households, are likely to need financial assistance to establish agroforestry, that provincial governments are now beginning to provide through incentive schemes and input subsidy (see below). For households with livestock, the use of grass strips provides immediate benefit from the value of livestock fodder, also critical for controlling livestock grazing to prevent damage to establishing trees.

Farmers showed a preference for more diverse agroforestry options involving several tree species, creating more relisient production systems in the face of anticipated price fluctuations for different products. The potential areas suitable for agroforestry expansion are 495,000 ha across Son La, Yen Bai and Dien Bien provinces, and using S-shaped diffusion curves to predict adoption with different assumptions regarding policy incentives and uptake it is estimated that from 128 to 250 thousand households could benefit over a fifteen year period of promotion.

Social outcomes: building social capital and growing markets. A co-investment scheme to support the establishment of exemplar agroforestry landscapes was facilitated by AFLi through building social capital amongst farmers, between farmers and extension workers and researchers, and between project staff and provincial governments.

For example in Na Ban village in Mai Son district, around a third of the farmers initially volunteered to put trees on their farms with technical assistance provided by the Son La extension centre and co-financing from the provincial DARD. This resulted in 50 ha of agroforestry in a landscape about three times that size, creating a showcase for how agroforestry can transform people’s lives and their landscsape. Nearly all the farmers in the landscape are now interested in adopting agroforestry and the provincial DARDs are co-investing in establishing a network of six exemplar landscapes across the region as focal points for promting agroforestry.

 

The project also facilitated partnership-building with the private sector, to grow the market for son tra (Docynia indica) an indigenous fruit tree which is being domesticated and promoted within the AFLi  project. Farmers can earn high incomes from growing the fruit, but as more farmers adopt improved tree germplasm, supply will increase and market prices would be expected to fall unless the market for the fruit expands. To effect this the project worked with National Institute of Medicinal Material in Hanoi (NIMM) and the Tay Bac Tea and Special Food company to develop non-perishible products from son tra including dried tea and extract that suit the urban market in Vietnam as well as creating the potential for export. The project is now working with the district government of Bac Yen, local farmers and the food company, to secure sustainable supply of quality son tra fruits for the market at attractive prices for producers.

Environmental outcomes: Soil erosion trials have shown that agroforestry is far more effective in controlling soil erosion than monoculture practices.  Compared to maize monoculture system, for example, the longan-maize-forage grass system on the 3rd year, suggest a reduction in soil loss by up to 56%; 23% in teak-plum-coffee-soybeans-forage grass; up to 90% in acacia-longan-coffee-forage grass system; and up to 74% in acacia-mango-maize-forage grass system. Once the trees reached maturity stage and the grass strips have become stable, erosion can be expected to be 90% less to zero. Not to mention improvements in on-farm biodiversity, the more than 60,000 trees of 18 fruit and timber species, planted by farmers in exemplar landscapes and FDTs would have significantly increased tree cover in the landscape with carbon sequestration benefits.

Contributing to change: AFLi research had a key strategy of harnessing volunteerism, co-operation and co-investment in its expansion from trial agroforestry systems to the establishment of on-station and on-farm trials and the management and monitoring of those trials, including research on propagation of priority agroforestry species and small-scale nursery development. And then to enhancing market access for focus species then exploring value-adding opportunities by smallholders and facilitating links between producers and other market actors. The key outputs from the strategy were disseminated through farm cross-visits, farmer field days and training sessions held at the test sites, accompanied by regular impact assessments and policy dialogue.

Research findings were used to inform the communication strategies, policy dialogues, extension and expansion activities through workshops, media products, extension materials and training.  This also involved major dissemination efforts through a network of farmer demonstration trials (FDT) and agroforestry exemplar landscapes to demonstrate large-scale agroforestry adoption. Outcome mapping was used to document the influence of the project on policy processes.

Communication and dissemination through various means (TV shows, videos, fact sheets, conference presentations, photo exhibits, blog stories, policy dialogues and training events) were critical to increasing the project’s visibility.

The project produced seven videos, of which, two were nationally broadcast. It also produced 17 blog stories, eight international and Vietnamese journal articles, four working papers, 20 technical reports, 14 extension materials, a fact sheet, a policy brief, and two information brochures.  Knowledge was also shared across large networks throughout Asia via presentations in major conferences such as: (1) Conservation Agriculture in Southeast Asia; (2) World Agroforestry Congress; (3) Asia-pacific Farmer’s Association; (4) Southeast Asian Network for Agroforestry Education; (5) and ALiSEA (6). Several other projects have made field visits to see the AFLi project achievements as a direct result of the project’s growing popularity, such as those of the SUFORD-SU PROJECT in Laos PDR, the IFAD-Ha Tinh project on Sustainable Rural Development, and the USAID-funded Green Annamites project.

Government policies and alignment: Through documentation of policy dialogues and processes the project outputs can be shown to have been important in the development of several national, provincial and district level policy instruments. These include:

  1. Yen Bai provincial Resolution15/2015/NQ-HDND— with provision for financial support of 6 million VND ha-1 for individual households or group of households, to establish son tra-based agroforestry practices in Tram Tau and Mu Cang Chai districts.
  2. Yen Bai provincial Decision 27/2015/QD-UBND—One time financial support at 1 million VND ha-1 for individual households to establish sustainable maize cultivation on sloping land by planting grasses along contour lines to reduce erosion.
  3. Yen Bai provincial Decision 2412/QD-UBND—Support for “son tra development in Tram Tau and Mu Cang Chai districts for the period, 2016-2020”. This involves Increasing the total area of son tra plantation to 10,000 ha, improving the existing 3,820 ha son tra plantation through use of better germplasm and management, and son tra planting on 6,200 ha of degraded forest land.
  4. Minisrtry of Agricultural and Rural Development (MARD) Decision 2477/QD-BNN-HTQT, at national level which created MARD’s Agroforestry Working Group that was set up to:
  • Advise MARD on agroforestry development in Vietnam
  • Review, improve, and propose agroforestry-related policies
  • Cooperate with local provinces, national and international organizations to research and develop agroforestry options for adaptation and mitigation of climate change
  • Capacity building for national and local staff and mobilizing funding sources for sustainable agroforestry development
  1. MARD’s inclusion of agroforestry in the National Action Plan Framework for Adaptation and Mitigation of Climate Change of the Agriculture and Rural Development Sector (2008-2020).

The enactment of above policies plus alignment with the government’s numerous strategies toward rural development green growth, and climate change adaptation and mitigation (ie, Vietnam’s Green Growth Strategy) has and will continue to stimulate wide-scale adoption of agroforestry in the region and beyond.

Some lessons learned were that wider adoption of agroforestry requires a combination of bottom-up and top-down strategies. Bottom-up work was required to develop feasible options with farmers that suit their circumstances; but top-down action from government to sanction and support agroforestry establishement is required for widescale adoption of agroforestry by famers across landscapes where land use is driven by competing, often incentivized options operating together with land designation and regulation.

AFLi as it stands today brings new insights about how smallholder farmers make decisions related to tree planting and adopting new production systems in changing policy, market and environmental contexts. In addition to the relevance of these results to policy makers and extension services, the research findings also enrich the scientific literature on constraints and opportunities for agroforestry adoption and on drivers of land-use change in general.

AFli further contributes to research on the role of indigenous species for afforestation and mixing with conventional trees and crops in agroforestry systems, such as son tra (Docynia indica). New knowledge generated through the trials on propagation methods of this species, productive combinations with other species and its potential to contribute to soil conservation are cornerstones of its domestication. This combines with new insights from value chain research on the opportunities and limitations for diversifying and strengthening existing livelihood options through adding value to products from remote, disadvantaged rural areas.

Trees for Food Security Project goal is to enhance food security for resource-poor people in rural Eastern Africa through research that supports national programmes to scale up the use of trees within farming systems in Ethiopia and Rwanda and then scale out successes to relevant ago-ecological zones in Uganda and Burundi.
Through the project, 5 Rural Resource Centers (2 in Rwanda, 2 Ethiopia and 1 in Uganda) and nurseries to enhance training and supply of improved tree germplasm have been established. The RRCs have provided business opportunities for farmer groups and unemployed youth particularly through grafted fruit trees.
This research forms part of the CGIAR Research Program on Forests, Trees and Agroforestry.

Marking World Water Day on 22 March, we are highlighting the essential links between forests and water. For more on this topic, check in to the live stream of the virtual symposium ‘Cool insights for a hot world’, hosted on 21-22 March 2017 by the CGIAR Research Program on Forests, Trees and Agroforestry (FTA).

New research has revealed a multitude of ways in which forests create rain and cool local climates, urging a closer look at forests’ capabilities beyond just climate change mitigation.

In a recent paper, 22 researchers from as many diverse institutions, call for a paradigm shift in the way the international community views forests and trees, from a carbon-centric model to one that recognizes their importance in cross-continental water cycles, as well as at the local scale.

“People are used to hearing the idea that forests are really important, but we now have a much deeper insight into why the loss of forest cover can have such a huge impact on water availability- especially for people downwind,” says study co-author Douglas Sheil from the Norwegian University of Life Sciences.

“The links are so much stronger than people previously thought. And if policymakers and land use planners are not aware of that, that’s a huge shortfall in decision making.”

So what exactly do we now know about forests and water?

Forests help raindrops form

Every day, forests replenish the supply of water vapour in the atmosphere. They draw up water through their roots, and release it from their leaves via transpiration. Along with evaporation from oceans and other water bodies, this is what drives the water cycle and charges the atmosphere with water vapor.

“The process is so powerful that it can be seen from space,” says co-author David Gaveau from the Center for International Forestry Research (CIFOR). “If you look at satellite images [above] of the Amazon, central Africa, or Southeast Asia, you can see these flashes of water vapor bubbling up.”

“We use the phrase ‘lungs of the planet’ all the time, but here you can really see this natural rhythm of forests actually breathing water vapor into the atmosphere.”

Recent studies have shown that as much as 70 percent of the atmospheric moisture generated over land areas comes from plants (as opposed to evaporation from lakes or rivers) – much more than previously thought.

In addition, new research has revealed that forests also play a key role in water vapor actually forming clouds and then falling as rain.

Trees emit aerosols that contain tiny biological particles – fungal spores, pollen, microorganisms and general biological debris – that are swept up into the atmosphere. Rain can only fall when atmospheric water condensates into droplets, and these tiny particles make that easier by providing surfaces for the water to condense onto.

Some of these plant-based microorganisms even help water molecules to freeze at higher temperatures – a crucial step for cloud formation in temperate zones.

“These particles are incredibly important for the occurrence of rainfall in the first place,” says the study’s lead author David Ellison, from Ellison Consulting and the Swedish University of Agricultural Sciences.  “If they’re missing, rainfall might not occur, or will occur less frequently.”

Trees can actually increase local water availability

Though the accepted orthodoxy is that trees remove water from catchments, and that planting trees reduces water availability for local people, another “game-changing” study has turned that assumption on its head.

“In a water-short environment, where people are digging their wells ever deeper because the groundwater is disappearing, it was believed that there’s a trade-off between planting trees and the water people need,” says Sheil. “A lot of donors have avoided supporting tree-planting in arid parts of the world because they see this as a conflict.”

But research conducted by Ulrik Ilstedt from the Swedish University of Agricultural Sciences, one of the study’s co-authors, has shown that in dry landscapes, trees (at some densities) can actually increase the availability of water, by assisting with groundwater recharge.

“What Ulrik has showed is that in the drylands of Africa, if you start planting trees you get an initial rise in the amount water in the landscape, because the trees actually use less water than the amount of additional water they allow to infiltrate through the soil,” Sheil says.

Tree roots – and the animals they attract like ants, termites and worms – help to create holes in the soil for the water to flow through.

“It’s pretty exciting,” says Sheil. “In huge areas of Africa, people can now start to plant trees. If you’re only interested in carbon, there are still lots of carbon benefits,” he says. “This is a win-win in every sense.”

Forests cool locally and globally

In tropical and temperate regions, forests cool the earth’s surface.  It’s not just that they provide shade – the water they transpire also cools the air nearby.

“One single tree is equivalent to two air conditioners, and can reduce the temperature by up to 2 degrees,” says study author Daniel Murdiyarso, from CIFOR.

Maintaining tree cover can therefore reduce high temperatures and buffer some of the extremes likely to arise with climate change, the authors say.

The effect can even be seen in urban environments, says Gaveau. “We all feel it – if you go to the park on a hot day, and you go under a tree, you’ll feel the cooling effect.”

Forests may draw moisture into the heart of continents

The authors also draw attention to a recent theory that proposes that forests create winds, bringing rain into the heart of continents – and that without continuous forest cover from the coast to the interior, rainfall would drastically diminish.

The ‘biotic pump’ theory includes physical mechanisms not present in current climate models, and still hasn’t been proven, but scientists from CIFOR believe it is credible.

The model proposes that forests generate low atmospheric pressure, sucking moist air inland from the ocean, creating a positive feedback loop.

“One value of this theory is that it allows us to explain how we can get really high rainfall in the interior of continents – the Amazon Basin in South America and the Congo Basin in Africa – when the original source of water, the ocean, is so far from where the rain is falling,” says Sheil.

Another of the study’s authors, Dominick Spracklen, has previously showed that across most of the tropics, air that has passed over extensive vegetation in the preceding few days produces at least twice as much rain as air that has passed over little vegetation – showing the immediate effect of deforestation on rainfall patterns.

Forests affect water availability downwind – not just downstream

The atmospheric moisture generated by forests doesn’t just stay in the local catchment. In fact, most of it is blown by prevailing winds into other regions, countries, or even continents.

“The more that you remove forests and other vegetation cover from terrestrial surfaces, the more you damage that cross-continental water transport,” says Ellison.

That has geo-political consequences that are not yet well understood.

“We want people to start to think in terms of ‘upwind and downwind’ dynamics. Where does your water come from, and how much does the catchment basin that you’re a part of contribute to downwind rainfall?”

“If you’re a land-use planner or a water management planner, what happens if you remove forests? How does that impact people downwind? If you’re in a catchment with a declining water supply, how might you influence that through upwind interventions?”

These questions require extensive collaboration between countries, new institutional frameworks that don’t currently exist, and new ways of thinking about water catchments.

For example, an international partnership called the Nile River Basin Initiative currently only includes the countries that are part of the actual Nile catchment basin and use its water, Ellison says. But the central African countries where the rain comes from are not involved.

“So then the question becomes, who should be involved in the management of a catchment basin, if the source countries for the moisture are somewhere else? How can they be included? Can you get them to recognise that what goes on in their country may be closely connect to what happens in yours?”

“You can easily understand how this leads to dilemmas,” he says.

A call to action

The link between forests and climate is intuitive, and easily understood by everyone, says Gaveau. “When you look at the morning mist rising from a forest, you see that forests are transpiring water vapor. If you sit under a tree on a hot day in a city, you’ll feel cooler.”

“At the moment, the nexus between forests and water is sort of treated as a co-benefit to the carbon story, but it should be front and center. Carbon can seem abstract to many people, but a glass of drinking water – that’s a tangible thing.”

Given the mounting scientific evidence for just how strong this connection is, the study’s numerous authors have issued a “call to action”.

We need a new way of looking at forests that prioritizes water, they argue – even within the global climate change framework.

Protecting forests to ensure access to water will inevitably also increase carbon storage, mitigate climate change, and have other immediate benefits, says Murdiyarso.

“If you are talking about carbon, you will see the results in 15, 50, or 100 years. But we see these cycling processes of water every day.”

“Hopefully, this approach can shift the paradigm, and the course of the debate on climate change adaptation and mitigation.”

We are only just beginning to realise how much life on earth depends on the partnership between fungi and forests. A recent video, released to mark the International Day of Forests on 21 March highlights new research into fungi in the Mekong region, including how local communities can benefit from harvesting and cultivating mushrooms – and how these benefits are linked to protecting forests.

Most people would agree that forests are a vital part of a healthy planet: around 1.6 billion people directly depend on forests for their livelihoods, and forest trees help provide us with healthy soils, clean water and even breathable air. The role of fungi is less well known. Yet without fungi, forests would not exist. In fact, without fungi, it’s unlikely that there would be much life on land at all – over 500 million years ago, it was a partnership between fungi and plants that allowed marine plants to colonize the land. Today, fungi continue to help forests grow by supplying trees with nutrients and breaking down organic matter.

Fungi are also a vital source of nutrition and income for many communities around the world, including in the Greater Mekong region, which comprises parts of China, Myanmar, Laos, Thailand, Cambodia and Vietnam. This area contains an astonishing variety of fungi, including many species which produce edible and medicinal mushrooms. Yet according to World Agroforestry Centre mycologist Dr Samantha Karunarathna, “while local people are keen to make use of this resource, they often don’t know how to identify wild mushrooms that are safe to consume – and they can struggle to sell their harvest for a good price.”

In response, the World Agroforestry Centre (ICRAF) and the Kunming Institute of Botany (KIB) are training local communities in mushroom identification, cultivation, harvesting and trade, and  have established the Southeast Asian Fungal Network to help communities and researchers share information. As ICRAF soil biologist Dr Peter Mortimer points out, “the project aims to give Mekong communities not only a reliable source of income and nutrition but also an incentive to conserve natural forests, which are the source of many of the most valuable mushroom species”.

ICRAF and KIB’s work on fungi in the Mekong region has been endorsed by the Mountain Futures Initiative, an international effort to find and support new projects that can improve the lives of mountain communities and safeguard their environments. The Initiative aims to plant the seeds of brighter, more sustainable futures in mountain regions around the world by bringing scientific research and traditional knowledge together.

The two organisations are also working together to catalogue the Mekong region’s fungal diversity: over 3,000 species are known to exist in this region, and over the past five years, 20% of the species collected have been new to science. However, continued deforestation means that these unique varieties of fungi – and their potential applications in medicine, agriculture and industry – are rapidly being lost. National and international support for further research and conservation efforts is therefore urgently needed to safeguard the future of this ancient partnership between forests and fungi.

Aligned with CIFOR’s 2016-2025 Strategy, this document serves as a ‘road map’ to putting the strategy in practice through our impact-oriented research, capacity building, and outreach and engagement activities. Produced on a yearly basis and reviewed at CIFOR’s Annual Meeting, it aims to guide funding partners, implementing partners and staff on CIFOR’s current and future plans to meet the most pressing challenges of forest and landscape management around the world.

In 2017, our work will happen at CIFOR locations across the globe. From Lima to Nairobi, to Indonesia, Vietnam and the Democratic Republic of the Congo, cutting-edge, dynamic research on forests and landscapes will continue to evolve. Major capacity building efforts with students worldwide, heading up a massive partnership involving multiple institutions and targeted data management initiatives are just some of the efforts we look forward to.

Find more details on CIFOR’s plans for 2017 in this document. We look forward to advancing our research on forests, landscapes and people, and to bringing positive impacts to all of the landscapes and communities where we work.

There is a lot of interest in the contribution that agroforestry can make to reverse land degradation and create resilient multifunctional landscapes that provide a range of socio-economic benefits. The agroforestry research agenda has been characterized by approaches that promote a few priority tree species, within a restricted set of technological packages. These have often not spread widely beyond project sites, because they fail to take account of fine scale variation in farmer circumstances. New methods are needed to generate diverse sets of agroforestry options that can reconcile production and conservation objectives and embrace varying local conditions across large scaling domains. Here, we document a novel approach that couples local knowledge acquisition with structured stakeholder engagement to build an inclusive way of designing agroforestry options. We applied this approach in the eastern part of the Democratic Republic of Congo (DRC) where armed conflict, erratic governance and poverty have resulted in severe pressure on forests in the Virunga National Park, a global biodiversity hotspot. Around the park, natural resources and land are severely degraded, whereas most reforestation interventions have consisted of exotic monocultures dominated by Eucalyptus species grown as energy or timber woodlots mainly by male farmers with sufficient land to allocate some exclusively to trees. We found that structured stakeholder engagement led to a quick identification of a much greater diversity of trees (more than 70 species) to be recommended for use within varied field, farm and landscape niches, serving the interests of a much greater diversity of people, including women and marginalized groups. The process also identified key interventions to improve the enabling environment required to scale up the adoption of agroforestry. These included improving access to quality tree planting material, capacity strengthening within the largely non-governmental extension system, and collective action to support value capture from agroforestry products, through processing and market interventions. Integrating local and global scientific knowledge, coupled with facilitating broad-based stakeholder participation, resulted in shifting from reliance on a few priority tree species to promoting tree diversity across the Virunga landscape that could underpin more productive and resilient livelihoods. The approach is relevant for scaling up agroforestry more generally.

Land tenure remains one of the most critical factors determining equity under REDD+, as we demonstrated through our previous article, ‘Roots of inequity: how the implementation of REDD+ reinforces past injustices”. Githiru responded to this paper, with some apparent challenges to both the empirical basis and theoretical arguments, that we had put forward. In this rebuttal, we demonstrate that there were no empirical differences between our original paper and Githiru’s response that had bearing on our findings, but that there are substantial differences in our interpretations of legality and equity, and consequently divergence about who can expect to benefit from REDD+. In a context where land ownership has historically and presently involved processes of dispossession, marginalization and even evictions, this rebuttal illustrates the complexity of the dominant discourse on land tenure and benefits under REDD+ and shows how social safeguards will need to take historical context and people’s current entitlements and agency into account, if equitable outcomes are to be defined and realized.
