Other challenges such as population growth, rural-urban migration, changing food preferences and drought exacerbate pressure on agricultural water productivity. The review critically assessed the different considerations for increasing agricultural water productivity under water scarce conditions in South Africa. While under these conditions, irrigation may seem an obvious solution to increasing agricultural water productivity as a response to frequent droughts and mid-season dry spells. However, considerations on the availability of water and energy for irrigation expansion and the accessibility of irrigation services to different farming groups in the country. It is generally argued that irrigation is an expensive option and not necessarily readily accessible to most farmers. There are prospects for tapping into South Africa’s groundwater resources but the extent to which they can contribute to expanding area under irrigation is contested given the challenges of quantifying and pumping the water. Most smallholder farmers currently lack access to water, energy, infrastructure and technical skills to irrigate thus making irrigation a challenging option in this sector. An alternative would be to explore rainwater harvesting and soil water conservation technologies, which involve inducing, collecting, storing and conserving runoff water for agriculture. The drawbacks to this are that, apart from scale issues, rainfall is becoming more erratic and droughts more frequent and hence the feasibility of this approach under frequent drought could be challenged.Item A model to integrate and assess water-energy-food nexus performance: South Africa case study(Conference Paper, 2019-09-01) Nhamo, Luxon; Mabhaudhi, Tafadzwanashe; Mpandeli, S.The main limiting factor impeding the operationalisation of the WEF nexus has been lack of metrics and tools to translate the concept into a fully-fledged operational framework to support policy and decision-making. This study developed a WEF nexus model by (i) defining WEF nexus sustainability indicators, and (ii) calculating composite indices for those indicators to establish numerical relationships among WEF nexus resources using South Africa as a case study. The composite indices show WEF nexus performance as well as monitoring and evaluation of WEF resources management. The indicators were integrated through the Analytic Hierarchy Process (AHP) in a multicriteria decision-making (MCDM). The established quantitative relationships indicate resource utilisation, management and performance through a spider graph to illustrate WEF nexus performance, providing a general overview of the level of interactions, interrelationships and inter-connectedness of resources. The shape of the spider graph is determined by the level of the interdependencies and interactions among the WEF nexus sectors, whose management is viewed either as sustainable or unsustainable depending on the classification of the developed integrated index. The spider graph for South Africa showed an over-emphasis on food self-sufficiency and water productivity at the expense of other sectors. The deformed shape of the spider graph is a demonstration of the sectoral or “silo” approach in resource management. The calculated integrated WEF nexus index of 0.203 for South Africa classified the country under the low sustainability category. The developed model is a decision support tool that provides evidence for interventions in priority areas. The model demonstrates the capabilities of the WEF nexus to evaluate synergies and trade-offs in a systematic and integrated way to increases efficiency and productivity in resource management for sustainable development.Item Transforming livelihoods and building resilience through multifunctional landscapes: Main findings and impacts(Poster, 2019-05) Tamene, Lulseged D.; Amede, Tilahun; Hagazi, Niguse; Solomon, DawitPoster prepared for a share fair, Addis Ababa, May 2019Item Harnessed flood water re-greens degraded pastoral lands in Ethiopia(Poster, 2019-05) Amede, TilahunPoster prepared for a share fair, Addis Ababa, May 2019Item Citizen science to fill hydro-meteorological data gaps in rural watersheds(Poster, 2019-05) Haile, Alemseged Tamiru; Nigussie, LikimyeleshPoster prepared for a share fair, Addis Ababa, May 2019Item Resilience through agricultural water management: Gender matters(Poster, 2019-05) Nigussie, LikimyeleshPoster prepared for a share fair, Addis Ababa, May 2019Item Application of deep tillage and Berken Maresha for hardpan sites to improve infiltration and crop productivity [Abstract only](Conference Paper, 2017) Muche, H.; Abdela, M.; Schmitter, Petra S.; Nakawuka, Prossie; Tilahun, Seifu A.; Steenhuis, Tammo S.; Langan, Simon J.Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affect infiltration and aeration resulting in increased rainwater use efficiency and agricultural production. However, rather limited information is available about the use of the Berken plough as a potential alternative for tillage practices. We studied the impact of improved tillage practices on infiltration, erosion, runoff and crop productivity during the rainy period of 2016 in Robit-Bata watershed located in upper Blue Nile, Ethiopia. The experiments were carried out in Maize fields where four tillage treatments were compared: (i) no-till (NT), no ploughing; (ii) conventional (CT), plots tilled three times using oxen driven Maresha, (iii) deep (DT), manual digging up to 60 cm using a mattock and (iv) Berken tillage (BT), plots tilled three times using an oxen driven Berken plough. Soil physical parameters (e.g. penetration resistance, bulk density) where measured before tillage treatment and after the cropping season. Additionally, crop performance (plant height, yield, residual biomass and root depth) and measurements on infiltration, sediment yield and runoff were collected. Tillage depth was significantly higher in DT (60 cm) followed by BT (27.58 cm) and CT (18.13cm). At the end of the season, the measured penetration resistance was significantly (p<0.01) lower at 20 cm depth in the DT and BT plots compared to the NT and the CT treatments. Infiltration rates increased from 115.2 mm hr-1(NT), 120 mm hr-1(CT) to 242.4 mm hr-1(DT), 261.6 mm hr-1(BT) (p<0.01) . The total runoff depth significantly decreased in the DT (29.46 mm) and BT treatments (33.53 mm) as compared to the CT (71.45 mm) and NT (98.77 mm) (p < 0.05). Similarly higher sediment yields were recorded for the CT (5.5 t ha-1) and NT (6.6 t ha-1) compared to the DT (2.6 tha-1) and BT (2.6 t ha-1) plots. Deeper tillage in DT and BT treatments as well as the presence of invisible barriers along the contour in Berken system could be the reason for the observed increase in filtration and the reduction of runoff and soil loss. On the other hand, the root length under DT was (> 50cm) followed by BT (>40cm) and NT and CT (both < 30 cm). Grain yield of maize was significantly lower in the NT (2.6 t ha-1) compared to yields measured in the CT (3.8 t ha-1), DT (3.8t ha-1) and BT (4.0 t ha-1) treatments (p <0.05). Results show that improved tillage practices such as deep tillage or Berken plough could increase permeability and herefore root penetration and agricultural productivity whilst decreasing erosion and runoff in the Ethiopian Highlands. The adoption of these techniques in the Ethiopian highlands could improve the sustainability of rainfed agriculture and reduce the environmental impacts associated with traditional tillage practices.Item Institutional of multiple-use water systems (MUS) in Nepal(Conference Paper, 2017) Clement, Floriane; Ahmed, FarahItem Crop ontology: integration of standard variables(Poster, 2016) Valette, L.; Pietragalla, J.; Laporte, Marie-Angélique; Afolabi, A.; Boukar, O.; Cannon, Steven B.; Diers, D.W.; Dreher, K.A.; Gaur, Pooran M.; Guerrero, Alberto F.; Hash, C.T.; Hualla, V.; Inoussa, D.; Kalberer, S.R.; Kondombo-Barro, C.P.; Kumar, S.; López Montes, Antonio José; Menda, N.; Nelson, R.; Ofodile, S.; Patil, S.; Prasad, P.; Rajendran, K.; Rami, J.F.; Rathore, A.; Sackville-Hamilton, N.
