Intensification


In late 2013, the Nile Basin Development Challenge developed eight key messages. Taken together, these messages form a new paradigm that can help further transform policies and programs and better enable poor smallholder farmers to improve their food security, livelihoods and incomes while conserving the natural resource base.

The sixth key message from the Nile Basin Development Challenge is to ‘integrate multiple rainwater management interventions at watershed and basin scales to benefit rainwater management programs.’ The NBDC took a landscape approach that integrated multiple rainwater management strategies affecting diverse users. The ultimate aim of this approachwas to multiply benefits within the landscape e.g. making water available for small scale irrigation, capturing rain water in semi-dry areas etc. Basin rain water management is more effective through such a landscape approach, as opposed to focusing on a plot of land or individual household only.

In late 2013, the Nile Basin Development Challenge developed eight key messages. Taken together, these messages form a new paradigm that can help further transform policies and programs and better enable poor smallholder farmers to improve their food security, livelihoods and incomes while conserving the natural resource base.

The first key message from the Nile Basin Development Challenge is to ’empower local communities and develop their leadership capacities to achieve long-term benefits and sustainable outcomes.’ Participatory design and planning on rainwater management interventions ensures key issues are addressed, the right pilot interventions are taking place and provides long term solutions with the commitment of everyone.

Considering that agriculture remains a key sector in Ethiopia, commercialization of the sector necessitates improving participation of smallholder farmers in markets, hence improving their incomes and livelihoods.

Promoting smallholder commercialization through cash crop production is one avenue of such efforts. The main argument for smallholder commercialization through cash crop production is that it can allow households to increase their income directly. Sesame in Ethiopia can be taken as a good example in this regard. Although Diga has a potential land and the area is among the few areas which are agro-ecologically suitable for sesame production and productivity in the country, smallholder farmers are not participating actively in its production (constrained by a number of factors).

This study assesses factors determining smallholders’ participation in sesame production in Diga, West Ethiopia. Using structured questionnaires, the data was collected from a random sample of 120 smallholder farmers and analysed by using a double hurdle approach.

After all, this study highlighted that access to credit, farm landholding size, family labour, household assets (oxen, donkey), access to family food for the whole year and proximity to extension service centres significantly influence smallholders’ decision probability of participating in sesame production. On the other hand, access to credit, number of oxen owned and number of active family labour significantly determine the level of smallholders’ participation in sesame production.

The implication is that production potential due to favourable agro-ecological condition is necessary but not sufficient for smallholder farmers to participation in sesame production. Indicating household specific and institutional factors also influence their decision. Thus, if active participation of smallholder farmer is required in the field, institutional innovations should be developed and strengthened—in a way to involve all smallholder farmers.

This paper was first presented at the Nile Basin Development Challenge Science meeting. The NBDC Science meeting was held on 9 and 10 July 2013 at the ILRI-Ethiopia campus, with the objectives to exchange experiences and research results across NBDC scientists involved in the NBDC projects and to discuss challenges and possible solutions.

The irrigation system in Kobo-Girrana valley is extensively developed into modern drip irrigation using ground water sources. Tomato and onion are among the major vegetables grown under drip irrigation. However, the drip lateral spacing is fixed to 1m for all irrigated crops. This leads to low crop water productivity, loss of land, less net return income and un-optimized irrigation production.

An on-station experiment was conducted to determine the effect of drip line spacing and irrigation regime on yield, irrigation water use efficiency and net return income. The experiment was carried out for two consecutive irrigation seasons in 2010/11 and 2011/12 at Kobo irrigation research station. The experimental treatments were: two lateral spacing of single row and double row corresponding to each test crop and three irrigation regime (Kp = 0.8, 1.0 and 1.2).

The results revealed that an interaction effect between the lateral spacing and irrigation regime was obtained in marketable yield and water productivity of test crops. Application of 0.8 Kp with 2m lateral spacing and 1.2 Kp with 1m lateral spacing provided relatively higher marketable yield of tomato and onion, respectively. Similarly, high water productivity was recorded with same irrigation depths and spacing regimes as to the yield.

This result generally revealed that one lateral design for each two plant rows gave high net income than the one lateral design for each one plant row for drip irrigated fresh marketable yield of onion and tomato. An optimized production and irrigation efficiency can be attained by applying irrigation depth adjusted by the given pan coefficients and drip lateral spacing in Kobo areas.

The reasons why farmers are unable to harness the benefits embedded in technologies and take advantage of business opportunities in livestock sector in developing countries remain unresolved.

Drawing on insights from innovation systems approaches, this paper assesses innovation constraints, identifies the bottlenecks and missing links in dairy sector and suggests some instruments needed to address the constraints.

We find that missing actors, limited capacity of existing actors, inadequate interactions between actors and poor coordination of activities along dairy value chain have been the major reasons for low technology adoption and underdevelopment of the dairy sub-sector in developing countries.

Future research should pay attention to designing, prototyping and experimenting with alternative institutional arrangements that can effectively coordinate inputs, services, processes and outputs in livestock value chains.

Six months before its formal end as a project, the Nile Basin Development Challenge (NBDC) hosted a science meeting to share ongoing and finalised research results.

Bedasa Eba introducing his paper60 participants met on 9 and 10 July 2013 and reviewed presentations organised around four main themes:

  • Livestock and irrigation
  • Water productivity, hydrological and erosion modeling
  • Rainwater, land and water resources management
  • Institutions, adoption and marketing

In addition, 10 posters were also featured in the science meeting, mainly from PhD and MSc students working in the NBDC. Presentations and posters are online.

Key lessons and conclusions emerging were:

  • The research for development approach adopted by the NBDC and other basins in the Challenge Program for Water and Food (CPWF) is valuable but it has not been able to go as far as planned, especially in terms of getting beyond research outputs towards development outcomes. See more about this in the presentation by Doug Merrey.
  • The Development Agents’ (DA) system has been somewhat left behind but have a crucial role to play and could be revitalised by actors like NBDC to involve DA staff in transdisciplinary research projects that can help move research outputs to outcomes.
  • NBDC research tends to focus on individual or household benefits of certain rainwater management interventions but less attention has been given to collective benefits and tradeoffs between upstream and downstream communities. The debate about on-site and off-site benefits and the link with ecosystem services at landscape level remains open.
  • Similarly, competition for water resources puts the stress on a new phenomenon: it is traditionally easier to promote individual technologies rather than collectively managed schemes (with their high transaction costs). However, adding too many individual pumps in the watershed stresses water resources.

The participants also highlighted a series of research gaps that ought to be taken up by future initiatives focusing on land and rainwater management (RWM). These included: appropriate land use planning, strengthening local agencies to deal with RWM and to plan land use, identifying suitable scalable solutions that are appropriate for a given context or focusing on scalable practices and methods or approaches; improving biomass production.

Finally, they noted that NBDC science remains somewhat scattered but the evidence base collected is an important asset to carry into other initiatives that will build on the NBDC legacy.

In April 2013, the Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) and Nile Basin Development Challenge (NBDC) jointly organised a ‘Training of Trainers’ workshop in the use of SLATE: A tool for Sustainable Livelihoods Asset Evaluation. The initial workshop was held in Addis Ababa. 30 participants from the Africa RISING’s four project sites and NBDC Innovation platforms attended the training. The training combined both conceptual and practical sessions in Jeldu woreda, one of the NBDC research sites.

SLATE has been developed by ILRI (International Livestock Research Institute) Scientist Peter Thorne. The SLATE tool uses the Sustainable Livelihoods approach of the United Kingdom’s Department for International Development (DFID) to think about scope, priorities and objectives for development.

The tool helps identify the range of assets and options open to households and get a clearer idea of the constraints and opportunities available to them. By concentrating on the range of different assets that are accessible to farm households, it ensures that these can be taken into account when designing development interventions.

How does SLATE complement NBDC innovation platform activities?

There is a recognized need to tailor soil and water conservation (SWC) interventions to specific socio-economic and biophysical conditions. The NBDC pilot interventions aim to improve collaboration between stakeholders at woreda level in order to ensure that SWC activities are better tailored to local contexts. Although farmers participating in the first year pilot interventions expressed an interest in fodder development, there had been limited consideration for the needs of different types of farmers. In order to improve the fodder interventions undertaken in 2013, innovation platform members realized they needed to consider variations in livestock holdings, land size and wealth between participating farmers as well as the inclusion of farmers without livestock. NBDC researchers organized the SLATE training to build the capacity of platform members to identify the needs of different farming households.

SLATE training

On the First day, Peter Thorne and Amare Haileslassie  shared the previous SLATE-based survey processes and findings undertaken at Bekoje, Arsi as well as the various steps around data collection and software demonstration. This was followed by a group exercise to familiarize the participants with the software.

For the field work, trainees were divided up in to three Kebeles (Seriti, Kolu Gelan and Chelanko) in Jeldu woreda of the Oromia Region, one of the NBDC Innovation Platform sites. During the first day of the field work, each group had a chance to meet and discuss with selected farmers to identify livelihoods indicators for their specific communities. With the selected farmers each group were able to identify 49-53 livelihoods indicators. On the second and third day individual household interviews were conducted with farmers (50 farmers in each kebele) to assess their asset status based on the already identified livelihoods assets indicators. The data collected from each household were then entered in the SLATE software to generate a set of livelihoods asset pentagons which gave a quick overview of the areas in which households and communities may differ.

On the last day of the training, participants presented review of the field exercise which covered the approaches they followed, the challenges and lessons learned, the results of their interviews as well as key issues for future considerations.
