Component 1: Developing technical capacities for climate-induced flood and erosion risks mapping and their use to inform climate-resilient integrated watershed management and other planning processes.

The Ntahangwa river connected to Bujumbura is a strategic asset that provides opportunities for productive sectors (e.g. agriculture, fisheries) but is also prone to climate risks and causes important damage due to erosion and landslides during wet seasons. Investments in parts of the Ntahangwa watershed have been made in the past, but they are insufficient to yield their intended results as they are scattered and not chosen based on an overall understanding of the watershed hydrologic processes and ecosystem services. A comprehensive integrated approach to land and water resources management of the Ntahangwa watershed is required to ensure long-term flood and erosion control and increased resilience of the communities in the watershed, including in areas at high risk of flood in densely populated areas of Bujumbura.

Under this component 1, capacities to analyse climate data and develop climate risk models will be enhanced to support climate-resilient integrated planning at the watershed level and inform communal development plans and flood-resilient urban development plans. The outcome under this component will address the first barrier to the long-term solutions identified in section 1. Interventions will cover the urban, peri-urban and rural settings, as they need to be considered together to understand the needs, priorities and constraints of populations in each of those areas to identify opportunities and synergies at the level of the watershed and attribute relevant role and responsibilities accordingly. For example, urban populations downstream need rural communities upstream to prevent soil erosion and reduce surface runoff causing flash floods. Rural communities need urban and peri-urban communities to access markets to sell their products.

Outcome1: Enhanced capacity for climate risk modelling and integrated planning in the Ntahangwa watershed and Bujumbura town

Under the LDCF project “Community based climate change related disaster risk management”, a community-based climate information system was developed to collect hydrological information and disseminate early warning information. 30 hydrometeorological stations were installed, with information collected centrally by the Geographic Institute of Burundi (IGEBU) and already covering the Ntahangwa watershed. As of 2021, the early-warning system should be operational, fully managed and funded by the government. Capacities and resources to make use of climate information will remains nonetheless limited and prevent use for planning and decision-making. Outcome 1 will build government capacities to expand the use of the climate information to better understand ecosystem health and their capacity to deliver benefits in terms of resilience under the current human, environmental and climate-related pressures. Modeling capacities also need to be enhanced to develop hydrological models to determine climate risks, more specifically flood and erosion risks, in the Ntahangwa watershed based on current climatic trends and future climate change scenarios. Those are pre-requisites for the development of an evidence-based, climate-resilient, integrated watershed management plan for the Ntahangwa river, as they will guide planning and decision-making processes.

Target areas for the World Bank-funded “Landscape Restoration and Resilience Project”, which constitute part of the baseline for land restoration and erosion control activities, were chosen in relation to their location in the Isare commune, but not primarily for their link to the Ntahangwa river. The resilient integrated watershed management plan will provide an understanding of the key areas in the watershed for the provision of ecosystem services for flood and erosion control and propose a watershed rehabilitation plan for those areas. The determination of priority areas will also confirm the critical gaps in the areas of treatment in the Ntahangwa watershed. Integrated watershed planning is an exercise requiring cross-sectoral cooperation and intense stakeholders’ consultation and participation, involving vulnerable and under-represented groups of people, such as women, youth, and indigenous people (n.b. indigenous Batwas are known to be present in the Ntahangwa watershed). The watershed planning exercise will make use of the climate information systems and climate-sensitive risk maps and evaluate adaptation solutions based on their geographical situation in the watershed. This should be complemented by ecosystem valuations to determine the economic value of ecocystem services provided by the watershed areas. Training will be provided to increase the capacity of relevant provincial and communal government officials, decision-makers and planners. The training will help them identify cost-beneficial ecosystem-based adaptation opportunities (rural as well as urban) and flood protection measures that address the climate threats facing the watershed.

The resilient integrated watershed planning exercise will be used to inform the preparation or revision of existing urban development plans in Bujumbura and communal local development plans in rural communes of the watershed. Those plans are the main tools to translate watershed-level planning into concrete field intervention on the ground while supporting long-term sustainability of the project activities and as a result long-term climate resilience.

Outcome 1 will support the other outcomes by creating the necessary basis upon which this LDCF project can conduct ecosystem restoration, flood protection and livelihood development activities to increase the resilience of communities in the watershed (in rural, urban and peri-urban areas). The evidence-based framework for planning and investment decisions will help ensure the sustainability and scalability of the project. Improvements to the climate information system will also help with collection of data and information that make monitoring and evaluation of the project’s impact easier to measure quantitively.

Outputs under Outcome 1 are listed below:

• Output 1.1: The community-based climate information system supported and improved to monitor changes in key ecological determinants of ecosystem health and resilience in the Ntahangwa watershed.

• Output 1.2: Training program implemented to enable the use of hydrological and climate models to map out climate-sensitive flood and erosion risks in the Ntahangwa watershed.

• Output 1.3: A resilient integrated watershed management plan prepared to guide the development and rehabilitation of the Ntahangwa watershed in areas critical for the provision of ecosystem services for flood and erosion control.
• Output 1.4: Flood and erosion risks maps developed for use in climate-resilient planning (urban development and investment in Bujumbura,  local development plans in communes of the Ntahangwa watershed).

Component 2: Landscape restoration and flood management measures to protect communities in the Ntahangwa watershed and Bujumbura from flood and erosion risks.

The area surrounding Bujumbura is the most prone to erosion and landslides, a situation which will increase over time according to climate projections[1]. Component 2 will build on the evidence base and the climate-resilient integrated watershed management plan provided in Component 1 to implement ecosystem-based adaptation (EbA) interventions and flood protection measures in strategic locations across the Ntahangwa watershed. The EbA interventions will restore or maintain ecosystem services for flood and erosion control while protective measures against flood will help stabilize critical riverbanks in at-risk populated areas of Bujumbura. This component represents the bulk of the investments proposed by this LDCF project and will complement and strengthen other investments made in landscape restoration, afforestation and resilience-building activities in parts of the Ntahangwa watershed (See Section 2 on Associated baseline projects).

Outcome 2: Ecosystems services for flood and erosion protection restored and flood protection measures implemented to improve the resilience of communities in the Ntahangwa watershed and in Bujumbura.

Under this outcome, the project will promote ecosystem-based adaptation techniques in the highland upstream areas of the Ntahangwa watershed. The specific measures include landscape restoration techniques and community-based anti-erosion measures. Landscape restoration techniques will focus on planting trees and creating quickset hedges to stabilize hills in the watershed and will be complemented by anti-erosion contour trenches and terraces. Those techniques are meant to reduce soil erosion, increase soil moisture and reduce surface water runoff, therefore improving ecosystem services provided by the watershed and its streams. During intense rainfall, contour trenches channel water runoff and reduce erosion and crop losses due to flooding. By increasing soil moisture, they also provide added protection against drought and heat waves on crops. These EbA techniques increase land productivity and food security. They bring additional economic benefits to communities as most of the hills in the watershed are used for agricultural production.

The landscape restoration efforts will be implemented directly with the local communities in each of the targeted hills in selected communes of the Ntahangwa watershed. Local authorities and local communities will enforce a ban on tree cutting and maintain anti-erosion trenches as part of their community work (half a day per week is dedicated to community work) under a labor-intensive public works (LIPW) scheme. Those EbA techniques are appropriate for a LIPW approach as they are low-tech and easy to implement and maintain with little capital. The LIPW approach has been applied successfully in Burundi for many years and is one of the approaches used to implement activities of the local development plans (e.g. Plan Communal de Développement Communautaire (PCDC)).

The risk mapping and modelling exercise undertaken under Outcome 1 and the watershed rehabilitation plan will help prioritize the hills and communes of the watershed based on their vulnerability to erosion and landslide and their contribution to the ecological status of the river and streams. This prioritization will also consider current and previous investments in the watershed to avoid overlaps and duplication as well as ensure that other interventions in contribute to addressing the climate threats facing the watershed. In total, the project will plant 3,000 ha of specific trees and herbaceous/shrubby quickset hedges in critical degraded areas as well as establish 1,000 km of contour trenches and radical terraces. 

Additional protection from flood will be provided through investment in protective infrastructures in lowland downstream areas, more specifically at-risk populated areas of Bujumbura close to the river. While Bujumbura is less prone to erosion, floods have devastating impacts on the city and the rivers flowing through it, including the Ntahangwa river where critical infrastructures such as schools, churches and habitation are directly at risk of collapsing. Climate change projections indicate that this situation will worsen over time, with increased variability between seasons and increased rainfall causing will increase the frequency of flash flood and landslides. Initial investments in flood protection measures was conducted along the river as part of the previous LDCF intervention. Those measures were considered a success by beneficiaries and the government. The risk mapping exercise under Component 1 will be used to determine the physical location and protective infrastructures options for implementation at a fine-scale level. This work involves civil engineering techniques to reinforce the sides of the river chanel with gabions and terraced surfaces. A social and environmental impact assessment will be undertaken before work on the riverbank can start.

These interventions will be supported by tools and technologies to increase communication and knowledge management at the community level to ensure better responses and handling when climate-related disasters occur. These will aim to create awareness and promote targeted interventions to shift response behaviours to improve climate resilience. South-South cooperation and exchanges of experience and lessons learned on EbA solutions for landscape restoration and urban-based flood protection measures will also be explored during the PPG. These activities will promote the sustainability and scalability of the project, in particular for their application in other rivers and watersheds connected to Bujumbura and Lake Tanganyika.

Outputs under Outcome 2 are listed below:

• Output 2.1: Restoration measures of vulnerable hilltops of the Ntahangwa watershed connected to Bujumbura completed through the methods of tree planting and quickset hedges;

• Output 2.2: Establishment of community-based anti-erosion measures, such as ditches and radical terraces, in vulnerable hills critical for the ecosystem health and resilience of the Ntahangwa watershed;

• Output 2.3: Flood control measures built along the Ntahangwa river channel in areas of Bujumbura where public and private infrastructures are at imminent risk of landslide during extreme climate events;

• Output 2.4: Knowledge and guidance material on (i) landscape restoration, and (ii) flood management and protective infrastructures prepared and disseminated within Burundi and via South-South exchanges.

Component 3: Livelihoods options and green entrepreneurship to increase resilience of the urban, peri-urban and rural communities in the Ntahangwa watershed.

Component 3 aims to support and strengthen the watershed restoration activities under Component 2 by inducing a shift away from unsustainable and vulnerable practices and livelihoods. Livelihoods enhancements and diversification activities proposed under this component will provide incentives to ensure participation and ownership of the project activities by beneficiaries and improve the long-term sustainability of the project results after it ends. The Ntahangwa river is strategic due to its geographic situation connecting highland areas highly sensitive to climate with major strategic assets for Burundi, the city of Bujumbura and Lake Tanganyika. While the connection between the urban, peri-urban and rural communities of the Ntahangwa watershed has been ignored or overlooked, the project will identify and build on the synergies between those communities to deliver win-win adaptation solutions benefiting populations of the watershed, no matter their location or situation. This component also provides specific entry points to support women, young people and indigeneous people with concrete resilience-building solutions or opportunities and tailored support and incentives. Although rural areas have higher poverty rates, the COVID-19 has had immediate and severe impact in urban areas due to the high dependance of the urban poor on informal and non-wage income streams which easily succumb to crises due to low capacity to adapt to sudden changes in market conditions. The livelihood options and green entrepreneurship opportunities proposed under this component build climate resilience while creating green jobs and contributing to building back better as part of the COVID-19 recovery efforts.

Outcome 3: Community livelihood is improved with sustainable adaptation measures contributing to urban, peri-urban and rural resilience.

This outcome introduces adaptation measures promoting resilient livelihoods options and green entrepreneurship opportunities building on synergistic opportunities between populations in urban, peri-urban and rural areas of the watershed and resulting in increased resilience to climate change for populations in the watershed. The options and strategies will be informed by a climate-sensitive market analysis looking at demand levers that could be used to trigger climate-resilient offerings reducing land degradation in the watershed. The market analysis will look at relevant value chains and supply chains to make recommendations on the feasibility and cost-effectiveness of climate-resilient strategies, both on-farm and off-farm. Relevant value chains and supply chains would include agricultural and food products, crops and farming inputs, livestock, fisheries, and non-timber forest products (NTFP). The market analysis will assess economic impacts and market barriers and will include mitigating strategies to address these barriers. The market analysis will be gender-sensitive and aim to provide specific strategies and options for vulnerable and under-represented groups. Food supply systems are key sources of livelihoods and income generating opportunities and can be instrumental in strengthening positive rural-urban linkages. The market analysis will consider COVID-19-related constraints on value chains and supply chains to identify resilience building solutions also contributing to a more robust recovery from COVID-19. The results of the market analysis will be used to inform urban and local development plans supported as part of Outcome 1.

Based on the results of the market analysis, the project will support 5 to 8 Ecosystem-based Adaptation solutions providing resilient livelihoods options that are also compatible with watershed resilience. Those solutions could include, but not limited to, family orchard, food processing and preservation, beekeeping, use of NTFP. Family orchard is a promising EbA solutions that could be used in the Ntahangwa watershed to develop small-scale cultivation systems optimizing the use of space and family labour to produce vegetables, herbs and fruits for both domestic consumption and supplemental income. Family orchard can be implemented in a variety of configurations in both rural and urban settings. Using crop diversification, families can produce food year-round and distribute losses due to climate-induced events. The technique contributes to food security and resilience, it can be complemented by other techniques for increased resilience and autonomy, such as water harvesting techniques, composting and seed management[2]. The project will explore food processing and preservation techniques for agricultural and NTFP products to create added value, reduce post-harvest losses, access new markets and diversify income opportunities, increasing general resilience to climate as a result. While this strategy can be applied to small producers, it could also apply to small agro-business enterprise development.

Under outcome 3, the project aims to foster innovation by supporting green entrepreneurship for urban/peri-urban adaptation. The project will provide investment and support for startup creation, capacity building and skill training, access to improved technologies, mentorship and networking. Green entrepreneurship will aim to tap into the potential of Burundi’s burgeoning startup community to come up with innovative solutions for urban and peri-urban resilience. This activity will provide employment opportunities and connect with young people and women, including those with higher education who often fail to find opportunities matching their career ambitions and expectations. For this activity, UNDP will partner with national, regional and global technological hubs, startup incubators and accelerators to connect startups and entrepreneurs with relevant actors and support. Through green entrepreneurship, the project will contribute to building a more resilient, greener economy in Burundi, which UNDP is promoting as a key recovery strategy post-COVID-19. In times of restricted mobility due to the pandemic, digital solutions are emerging as essential to keep businesses active and ensure safety and security. Where possible, the project will use innovative digital tools to make green businesses easier, more inclusive and more capable of sustaining services during crisis.

UNDP initiated discussions to partner with Impact Hub Bujumbura, a local technology hub supporting Burundi’s startup ecosystem to tackle the Sustainable Development Goals via entrepreneurial and innovative solutions. To generate ideas and interest, the project will support Impact Hub Bujumbura with the organization of the first Climathon in Burundi, Climathon x Bujumbura. Climathon is hackathon programme organized globally under the auspice of Climate-KIC to translate climate action solutions into tangible projects for climate positive businesses and start-ups and addressing local policy changes. Climathon x Bujumbura will gather the startup community to come up with innovative solutions for adaptation and urban resilience. The project, with support from UNDP, will seek to connect startup and entrepreneurs with resources and actors in Burundi, including funding (e.g. UNDP Acceleration Lab, Climate-KIC Accelerator).

Lessons learned from the GEF-LDCF project “Community based climate change related disaster risk management” will be used to guide and inform some of those activities for green entrepreneurship. Such activities include a pilot initiative for briquette production from recycled waste for cooking that is ready for upscaling. Charcoal production is an important driver of deforestation and land degradation in Burundi and the production of briquettes from organic waste contributes to reducing the reliance on wood for charcoal production. The pilot initiative supported by UNDP has created an additional source of income for over 20 young people, men and women, who have learnt the skills needed to prepare the briquettes from waste and build improved cooking stoves. The initiative is generating revenues and has identified areas to improve production bottlenecks for further expansion (e.g. shaping of briquettes with a motorized engine instead of manual work). The market analysis will provide solutions and de-risking incentives to upscale this initiative and will support the establishment of additional briquette production units with, among others, skill training and marketing training, improved production equipments and access to finance.

To facilitate investments and entrepreneurship, the project includes a specific activity on access to micro-finance for smallholder farmers and small-scale entrepreneurs, with a specific focus on women and youth entrepreneurs. This will include capacity building in financial literacy to give beneficiaries a better understanding of credit and business models applicable to their livelihood activities. The project will establish partnerships with banks and micro-finance institutions to develop credit products at affordable interest rates and accessible by vulnerable groups. During the PPG, de-risking measures to incentivize micro-finance institutions and banks will be explored. Strategies to facilitate positive impact on women and other vulnerable groups will form the basis for tailoring policies, practices and products that better address gender equality and promote women’s empowerment. The project will train MFI’s staff member on gender analysis and help them incorporate empowerment indicators (e.g. proportion of women in the loan portfolio) into their client monitoring and assessment processes and help them adjust their financial services to respond to diverse client needs (e.g. adapting loan amounts and repayment schedules for women). The project will build on and strengthen women’s network and conduct marketing campaigns to influence people’s attitudes on women’s status and employment to facilitate community approval of women’s projects and build women’s self-confidence.

As in Outcome 2, Outcome 3 will promote communication and knowledge management, and explore mechanisms to share experience and lessons learned and promote sustainability and scalability of the project’s livelihood options for EbA and green entrepreneurship initiatives.
