The CGIAR Challenge Program on Water and Food just published a new report from the Nile Basin setting out ways to enhance rainwater management (RWM) development processes.

In Ethiopia, considerable potential exists to enhance food production and rural livelihoods through better rainwater management – interventions which enable smallholder farmers to increase agricultural production – focusing on livestock, trees, fish as well as crops – by making better use of available rainwater while sustaining the natural resource base (water and soils) in rainfed farming systems.

Ethiopia has invested extensively in RWM interventions, in particular soil and water conservation and afforestation, over the last 40 years, but often with disappointing impact, for multiple reasons. Given this limited success in natural resource conservation, a new approach is clearly needed, but what should it be?

This report highlighted various livelihood issues that need to be considered if RWM activities are to be successful; it concludes with six recommendations:

  1. Shift the focus of targets from outputs to outcomes;
  2. Enhance monitoring and evidence collection on RWM with a focus on impact and sustainability;
  3. Revitalize and capitalize on the development agent system;
  4. Strengthen local institutions’ roles in natural resource management;
  5. Move towards more meaningful participation;
  6. Open lines of communication to foster innovation capacity.

2013 is the final year for the Nile Basin Development Challenge (NBDC). On 20 and 21 February 2013, the NBDC convened a meeting of the  National Land and Water Management Platform to review progress and directions for the coming phase.

The workshop reflected on past work – approaches developed, research findings, key messages – in order to prioritize future interventions. Over 60 participants from partner organizations and other governmental, research and non-governmental institutions participated to the two-day workshop.

After an introduction to the NBDC timeline, some key messages compiled by project staff were presented and discussed. A series of NBDC approaches, methods or areas of work were introduced later in the day: innovation platforms and recent insights, modeling, Wat-A-Game, Happy Strategies game, GIS, Goblet tool and suitability maps, participatory hydrological monitoring, digital stories and participatory video, and local planning processes.

The participants formed groups to discuss the relevance of the messages they heard and to identify priority activities to build upon NBDC work and embed it in organizational and individual practices. A special policy session also looked at possible contributions of the NBDC to priority development challnges in Ethiopia.

At the end of the workshop, the Nile basin leaders Simon Langan and Alan Duncan reflected on the feedback received and the directions that the NBDC will take. Key directions include: repackaging research in accessible ways for farmers, policy-makers and other organizations; focusing on capacity development; finding practical ways to bring farmers’ and scientists’ voices together in crafting common approaches and discourse; addressing the regional gaps between local level work and national level engagement; and joining forces with existing initiatives that can reinforce the messages of the NBDC such as the Sustainable Land Management program.

Charlotte MacAlister, hydrologist at the International Water Management Institute (IWMI) and team leader for the Nile BDC project on ‘Assessing and anticipating the consequences of innovation in rainwater management systems‘ left Ethiopia in late January. She will start working for Canada’s International Development Research Centre (IDRC).

In this interview she shares some views on her involvement in the Nile BDC , her perspective on relative successes and challenges for her work in NBDC and some advice for the final year of the project.

What range of activities have you been involved in?

I joined IWMI in Ethiopia in 2010 and started in the week of the NBDC inception meeting.

I have been involved in the program management of the ‘Nile 4′ project and generally in basin scale water resource and hydrological impact modelling. More specifically, I have been working on training and capacity building (both internally and externally), spatial analysis and modelling, the development of water resource management tools and the generation of a data archive for the Nile Basin.

What has been successful / what are you most proud of?

Quite a few things worked well:

  • Some innovations in the application of global climate data sets.
  • The distribution of free climate data for any user (not restricted to the NBDC), i.e. with open access data sets available on the web.
  • The development of high quality, robust hydrological models of the Blue Nile using real data.
  • We have built strong linkages with local research partners (e.g. the Universities of Bahir Dar, Ambo, Arba Minch) and with governmental agencies (Abay basin authorities, Tana river basin organization, Beles river basin organization, the Ministry of Water and Energy).
  • The training and support of master students who graduated. Over the course of my involvement, we had six MSc students graduate, supported by the program.
  • Initiating the spatial analysis and modeling (SAM) topic working group for cross-basin learning.

What has been most challenging, why?

The technical challenges of modelling large and mostly ungauged basins (no rain /flow or sediment gauge) meant that building the model was difficult: How can you assess impact without data?

After we set up our models, we faced another challenge: the general lack of understanding about different interventions. We have estimates and guesses about what intervention might work where but we don’t really have any measure of impact and we cannot easily use modelling effectively for that reason. What we actually need is experimenting on catchment with different practices to find out what the physical impact of interventions will be – before and after. There is no way to get around that.

As a result of the above, another challenge was the lack of any direct impact by which we could monitor change. We are expected to assess impact without implementing any intervention. If I were to do this by myself I would start with engaging on the one hand a community that wants to make changes and on the other hand another one that does not want to make changes. Over five years I would then have time to see changes and assess impact. When your job is to quantify impact, it is difficult to work in these conditions and qualitative approaches are not enough. People in the Ministry of Water and Energy want real evidence of impact, at least within a range, to see if a practice can be scaled up.

Finally, what was also challenging was the way the project was structured: Splitting the NBDC across scales rather than themes (e.g. hydrology, economics etc.) made the project organization somewhat cumbersome.

What lessons learned will you use or build upon in your next job?

First and foremost, in a project, engaging with key partners in communities and among governmental agencies from the design of the project and at the stage of defining project outcomes is key to success.

Another lesson is that we are not that much closer to appreciating and valuing each others’ perspective between social scientists and biophysical scientists.

However, I want to continue using and promoting the tools we developed; I would like to keep some relation with the SAM group. A lot of people are working on similar issues around the world. Why not share learning across them and across communities? Our lessons don’t have to be  restricted to the different Basin Development Challenges, they can also benefit communities.

Where are you headed? Will you keep working (in some capacity) with the NBDC?

I’m going to be working as senior program officer at the water and climate change division of IDRC. I will be working on water and climate change projects in Southern Africa and South Asia. It is unlikely that I will continue collaboration with the NBDC.

Any advice to the NBDC for the final year?

Focus on what is working now and on the productive relationships that have been developed. Do not be afraid to drop activities.

One of the objectives of the Nile Basin Development Challenge – registered as one of the outcomes that the program hopes to achieves – is to develop the capacities of various actors, including of future generations of decision-makers, planners and implementers of land and water management policies and interventions.

Over the past, the Nile BDC has hosted the work of various students to develop their theses. Here is a tour of some of these:

For the final year of the Nile BDC, a few more theses and pieces of work can be expected.

Best practices for rainwater management in the Ethiopian Blue Nile are well known. They include many practices related to crop livestock and trees that increase water availability or productivity within the watersheds, such as soil and water conservation, small scale irrigation, fertility management, or livestock management. Nonetheless, adoption of many of these practices is still low, mainly because they have been promoted in locations where they are not suitable, or have not been combined with symbiotic practices that would result into real benefits for farmers.

Rainwater management practices therefore need to be combined at landscape scale to form rainwater management strategies. These strategies fit a specific context that is defined by the bio-physical, socio-economic and institutional constraints. In other terms, best bet rainwater management strategies are location-specific and best practices should be combined differently in different locations.

Suitability analysis

In geographic information systems (GIS), suitability analysis is a procedure that allows to select locations where a given practice is suitable. It is a four-step procedure :

  1. Selecting bio-physical suitability criteria
  2. Selecting the geographical layers that represent the bio-physical suitability criteria
  3. For each criteria, selecting location from the geographical layer where the criteria is met (in other words, creating criterion maps)
  4. Selecting all locations where all criteria are met (overlaying criterion maps) and creating practice suitability maps

For the Nile basin, adoption maps were created, based on economic models. These show the percentage of farmers that are predicted to adopt a practice, given the socio-economic and institutional constraints. When the suitability maps are overlaid with adoption maps, a feasibility map is created that shows how many farmers will likely adopt the technology on a suitable location allowing to prioritize locations with suitable socio-economic conditions.

The Nile Goblet tool

The Nile Goblet tool (also presented here) is an open source GIS tool that allows easily to make suitability and feasibility maps without prior GIS knowledge. It is a very flexible tool that in principle allows to map any practice for any location of the world, and helps consider combinations of practices. A database has been developed which includes all the (freely) available layers for the Nile basin, as well as the suitability thresholds suggested by the “integrated participatory watershed management guidelines” from the Ministry of Water and Energy.

Using the results of the tool on the ground

The maps resulting from the tool can be very inaccurate, due to the scale and inaccuracy of the input data. As such the maps present windows of opportunities based on expert knowledge of what communities could do. Action on the ground should help unlock local knowledge and complete this picture. Implementation should therefore be done in a participatory manner for instance with approaches such as the ‘happy strategies’ game. It can enable a dialogue between communities, non-governmental organizations and local government agencies around rainwater management practices, so as to validate the maps and come up with a feasible plan on the ground.

Conclusion

Offering a tool that allows policy-makers and practitioners to introduce their own or expert knowledge about suitability criteria into a transparent procedure will help them understand and trust the resulting maps, better understand why promotion of rainwater management should be location-specific and move away from today’s blanket approaches. Indeed, the resulting maps can support the elaboration of context-specific policies. In combination with the happy strategies game, the maps also enable expert knowledge to blend into a participatory approach and improve the planning on the ground with communities.

Catherine Pfeifer, Post-doc at the International Livestock Research Institute (ILRI) and the International Water Management Institute (IWMI), is going back to Switzerland in late December. For the past three years, she was involved in the Nile Basin Development Challenge project (‘N3′) on ‘Targeting and scaling out of rainwater management systems‘.

In this interview she shares some views on her involvement in the NBDC  and particularly her work around gaming solutions for targeting relevant land and water management options.

What range of NBDC activities have you been involved in?

My main activity has been the Nile-goblet tool, including finding the data, setting up the database (linked to our suitability data), developing the concept of the tool. In a way, the Nile-goblet brings everything from the N3 project together: concepts, suitability data and adoption maps. This work aims to explain how to introduce socio-economic constraints in biophysical targeting.

The other main activity has been the Happy Strategies game which helps people assess most suitable land and water management interventions in a given area.

In addition to this, she did a lot of capacity building: A one-week training on geographic information systems (GIS) in 2011 and two training courses more recently this year. Finally there was the learning event last week which introduced the Nile-Goblet tool to members of the NBDC national platform thematic working group on technological innovation.

What has been most successful / what are you most proud of?

The tools: the Nile-goblet and the Happy Strategies game. They are taken up by partners (the Water and Land Resource Centre will further promote and work with those tools. They are considering developing them further in future learning events of the thematic working group on technological innovation. The reason I am proud: our initial objective was to get other people involved in developing these tools and we seem to have achieved this objectives.

Working with partners has generally been successful, despite challenges (see below).

The Spatial Analysis and Modeling topic working group has also been great to work with and quite a success.

What has also been successful is the work in our team: as the GIS specialist, I could take care of the adoption maps and developed a participatory tool. The team was very flexible throughout the process. I had enough freedom to do the things the way I thought they should work out.

What has been most challenging? Why?

Working with partners has been challenging at times, but we overcame challenges.

The other challenge was the integration with other NBDC projects. The program aimed to work in an interdisciplinary manner but it hasn’t always worked, perhaps because of the the way the project was set up. I wonder if we really had the space to develop such interdisciplinary work. At any rate we haven’t really worked together across teams as much as we could have. Every team worked in its interdisciplinary approach but this didn’t extend across projects. We missed opportunities to think together about how outputs could have been developed.

What lessons learned will you use or build upon (from your NBDC work) in your next job?

I want to keep working on integrating socio-economic constraints in spatial models. There is scope to understand how this integration works much better. I learned a lot about it in the past two years but there’s a lot of space for improvement still.

What I also really learned was how important it is to involve farmers and mix expert and local knowledge. For example we can do this geographic targeting but it will never be perfect. We need a space to interact, validate and learn and adjust, which is what we tried to offer with the Happy Strategies game. That integration is something where the CGIAR is very strong.

I also learned to not be scared, to trust that things will work out in the end somehow…  Three years ago, I would have been scared to talk to farmers and now I’m ready for it any time.

Any advices to the NBDC for the final year?

  • Get the right people involved at the right moment. E.g. the learning event was small but it brought together interested people and they will take it up.
  • Move away from trying at all costs to bring the diversity of the NBDC together. Think also about bringing similar people together to take over the work. Perhaps in our innovation platforms we would do well to reduce the diversity and invest in people that will take things up.
  • Mind the fatigue of our partners. Only invite partners that can really benefit from the events we organize. Otherwise there is a risk of a lot of talking and nothing much happening. And some partners are investing precious time and money in the events we organize, we need to remember that when planning our meetings.
  • Don’t get lost in interdisciplinarity: Try to link the NBDC teams and people but don’t try to force them to work together. There is a lot of good work that could be used at different scales and for different people. Not everything needs to be integrated.
  • If you really want to integrate the NBDC work, develop a Google layer and look seriously into collecting geo-coordinates for each NBDC output, so it can be shown on Google Earth and linked to actual NBDC documents. This could be the easiest way for NBDC to integrate our work. If I were to stay another year I would work on that and try to develop a public layer on Google Earth or a KML file (for Google Earth) which people can download, click on and display the NBDC outputs.

How do you look back at the whole experience?

I had a great time. I loved my job. I loved the fact that my job was free, despite the occasional tensions. I’m happy to see it finish nicely.

The first learning event of the thematic working group on technological innovation (1) of the national platform on land and water management took place on 6 December 2012. The event brought together representatives from the Amhara Regional Agricultural Research Institute (ARARI), the Water and Land Resource Center, Nile river basin authorities, the Ethiopian water harvesting association (ERHA), and the Swiss Agency for Development and Cooperation. All participants were invited to discover and test the new open source geographic information system (GIS) tool for suitability mapping “Nile-Goblet” and to ponder how to bring technical innovation on the ground.

The participants liked the tool very much, for its ease to make suitability maps without prior GIS knowledge. They also appreciated the fact that the tool allows anyone to introduce their technical expertise or local knowledge about suitability criteria following a very a transparent procedure. Subsequently, policy-makers and practitioners can identify with, understand and trust the resulting maps.

The tool is expected to emphasize the necessity to promote location-specific rainwater management and to help move away from today’s one-size-fits-all blanket approaches. Indeed, the maps generated by users can support the elaboration of context-specific policies. In combination with participatory approaches such as the Happy Strategies game, the maps also allow bringing in expert knowledge into a participatory approach and improving planning on the ground, together with communities.

Participants of the learning event found it very useful to come together to learn and discuss. It is likely that this group will meet again and possibly combine learning events with other events that are already planned and funded. Additionally, the Water and Land Resource Center – in collaboration with the Swiss Agency for Development and Cooperation - will look into opportunities to use and promote the Nile-Goblet tool for their own work.

On the second day of the workshop, an informal training course took place, aiming at adapting the tool for participants’ own needs.

The learning event brought together a budding community of practice which seems truly interested in location-specific rainwater management and has the capacity to carry out the work of the Nile Basin Development Challenge in this field further along.

On 18 December 2012, the learning event was followed by another introduction to the Nile-Goblet tool, this time for CGIAR staff in Ethiopia.

Notes:

(1) The national platform on land and water management launched four thematic working groups in the course of 2012. Technological innovation is one of these working groups.

Planning NBDC activities for researchers (Photo credit: ILRI/Le Borgne)The Nile Basin Development Challenge (NBDC) is entering its final year. By December 2013, all activities funded through the Challenge Program for Water and Food (CPWF) need to be complete.

A planning exercise on 15 and 16 November brought the core partners together to re-arrange priorities around specific outcomes and target groups that NBDC intends to influence.

About 25 participants representing the remaining four NBDC projects (the stock-taking project ‘Learning about rainwater management systems‘ ended earlier on) took part to the meeting.

Over the two days, participants:

  • reviewed the outcome logic model (the planning/monitoring framework) informing their activities to assess its validity in the current context,
  • took stock of important assets that the NBDC should capitalize on, in terms of outputs produced, networks strengthened and capacities developed,
  • discussed the integration of these assets and activities to support five key stakeholder groups: farmers and farming associations, researchers, planners, policy-makers and the internal NBDC team,
  • developed action plans to align these activities,
  • identified activities for cross-cutting issues such as gender, monitoring and evaluation, the sunrise strategy that is expected to ease the dawn of the program and a final session to plan the external stakeholder meeting in February 2013,
  • filled out a timeline of the project that tracked back important events, outputs, changes in the network or in the attitudes and skills of stakeholders. Participants were energized by the large numbers of outputs already produced as well as the extent of the capacity and network building efforts.

The workshop was a strong exercise in integrating across all the teams; it brought all the ‘N-project’ teams together around cross-cutting outcomes by stakeholder groups.

The next step in this planning is a full stakeholder meeting in February 203. Thereafter, the countdown for the NBDC will really tick with a renewed sense of urgency.

On 12 November 2012, 26 participants attended a  ‘symposium on modeling in the Blue Nile / Abay Basin‘. It was organized by one of the projects of the Nile Basin Development Challenge (NBDC) – the so-called N4 project on ‘Assessing and anticipating the consequences of innovation in rainwater management systems‘.

Building upon recent results of this project, the team invited representatives from Nile Basin Authorities, the Ministry of Water and Energy and the Nile Basin Initiative Decision Support System Office to map out existing modeling work and to identify priorities for water resource and agricultural water management modeling in the Blue Nile Basin.

Past and current experiences

The presentations from the Nile Basin (Tana and Beles sub-basin) Authorities, from the Ministry of Water and Energy, from Bahir Dar University and from the Ethiopian Institute of Water Resources highlighted a wide spectrum of experiences. These presentations were later completed by additional presentations from NBDC scientists to form a collection of experiences spanning climate modeling, hydrological modeling, crop productivity modeling, economic modeling tools. The final presentation emphasized the need to integrate biophysical and socioeconomic model outputs and kick-started the discussion among participants.

The different presentations emphasized a number of crucial common challenges preventing modeling from being more fully exploited or useful in agricultural water management and water resource modeling initiatives: the diversity of modeling tools and their inconsistent use, the lack of good quality data, the insufficient capacity to use existing modeling tools, the lack of integration of modeling outcomes in planning and implementation strategies.

Ways forward

Later in the afternoon, participants discussed the key priorities for agriculture-water and water resource modeling in the Basin, related to either:

  • Scaling issues (integrating small scale practices and large scale impacts in planning and management)
  • Data needs
  • Uptake and acceptance of model outputs

In terms of scaling, the selection of scales depends on different variables (hydrology / erosion, population, greenhouse gas emissions, economic process, spatial variability). In turn, what is to scale varies with the scale: spatial variability, system dynamics variation within t, factors such as runoff capacity. Small scale modeling works better for better characterization of an area and at any rate there is always uncertainty in modeling for planning and management.

As regards data needs, all agreed that the main challenge was how to access data. All of the group were familiar with the bottleneck in getting met data, and the generally low resolution of soil and landcover data. The group also agreed on the need to update a range of data sets including hydro data and land cover-land use. The group also discussed the problem of numerous ungauged basins in terms of met and flow data. Some potential opportunities to use remote sensed data to fill these gaps were discussed and the International Water Management Institute (IWMI) team distributed a MET data set for Ethiopia derived from the US-NCEP CFSR (Climate Forecast System of Reanaysis) global weather data set, prepared by IWMI staff and Cornell researchers to make it useable in Ethiopia.

Finally, in terms of ensuring acceptance and uptake of modeling, a number of factors play out. The first and foremost is to think about the relevance of modeling data for the target audience, but issues of data quality, modeling complexity (and its potential to be communicated clearly) also affect the acceptance. Models should not be trusted – rather their outputs should be verified before their outputs are communicated to intended end users. In order to improve uptake of modeling outputs, the participants highlighted various strategies: tailor modeling output messages to different target audiences, develop capacities (both of modelers to communicate their outputs and of end users to use them), use various communication outputs (policy briefs, face-to-face sensitization etc.) and to engage with intended audiences throughout the process.

This symposium was the first of its kind and perhaps layed the first stone on the way to a water-agriculture modeling community of practice.

Three projects supported by the CGIAR Challenge Program on Water and Food provide the contents of a book published today. ‘The Nile River Basin: Water, Agriculture, Governance and Livelihoods’ provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream-downstream linkages, innovations, future plans and their implications.

It elaborates the history and the major current and future challenges and opportunities of the Nile river basin. It analyzes the basin characteristics using statistical data and modern tools such as remote sensing and geographic information systems. Population distribution, poverty and vulnerability linked to production system and water access are assessed at the international basin scale, and the hydrology of the region is also analysed. It provides in-depth scientific model adaptation results for hydrology, sediments, benefit sharing, and payment for environmental services based on detailed scientific and experimental work of the Blue Nile Basin.

The Book is edited by Seleshi Bekele Awulachew, formerly with the International Water Management Institute (IWMI), Vladimir Smakhtin (IWMI), David Molden (formerly IWMI), and Don Peden, consultant at the International Livestock Research Institute (ILRI).
