    • Deep Tillage Improves Degraded Soils in the (Sub) Humid Ethiopian Highlands 
      Abidela Hussein, Misbah; Muche, Habtamu; Schmitter, Petra; Nakawuka, Prossie; Tilahun, Seifu A.; Langan, Simon; Barron, Jennie; Steenhuis, Tammo S. (Land; Texas &M University. Libraries, 2019)
      Intensification of rainfed agriculture in the Ethiopian highlands has resulted in soil degradation and hardpan formation, which has reduced rooting depth, decreased deep percolation, and increased direct runoff and sediment ...
    • Establishing irrigation potential of a hillside aquifer in the African highlands 
      Tilahun, Seifu A.; Yilak, Debebe L.; Schmitter, Petra; Zimale, Fasikaw A.; Langan, Simon; Barron, Jennie; Parlange, Jean-Yves; Steenhuis, Tammo S. (Hydrological Processes,; Texas &M University. Libraries, 2020)
      Feeding 9 billion people in 2050 will require sustainable development of all water resources, both surface and subsurface. Yet, little is known about the irrigation potential of hillside shallow aquifers in many highland ...
    • Evaluation of CFSR, TMPA 3B42 and ground-based rainfall data as input for hydrological models, in data-scarce regions: The upper Blue Nile Basin, Ethiopia 
      Worqlul, Abeyou W.; Yen, Haw; Collick, Amy S.; Tilahun, Seifu A.; Langan, Simon; Steenhuis, Tammo S. (CATENA; Texas &M University. Libraries, 2017)
      Accurate prediction of hydrological models requires accurate spatial and temporal distribution of rainfall. In developing countries, the network of observation stations for rainfall is sparse and unevenly distributed. ...
    • Feed the Future Innovation Lab for Small-Scale Irrigation: Ethiopia - Proceedings documentation 
      Adie, Aberra; Duncan, Alan; Haileslassie, Amare; Worese, Hailesellasie; Sileshi, Ayele; Shapiro, Barry; Hurrissa, Belachew; Iyob, Biniam; Jones, Charles Allen; Negassa, Asfaw; Mekonen, Kindu; Thorne, Peter; Seifu, Admassu; Desta, Solomon; Mengistu, Solomon; Alemu, Ermias; Namubiru, Eveega; Lebedi, Fethia; G/Tsadik, Fikru Haile; Gebregziabher, Gebrehaweria; Bonger, Gebru; Gebru, Getachew; Legesse, Getachew; Getahun, H.E.

      Ethiopia - Proceedings documentation
    • A review of trends, constraints and opportunities of smallholder irrigation in East Africa 
      Nakawuka, Prossie; Langan, Simon; Schmitter, Petra; Barron, Jennie (Global Food Security; Texas &M University. Libraries, 2018)
      Smallholder irrigation expansion would significantly increase agricultural production, and reduce food insecurity and poverty levels in East Africa. This paper reviews literature on trends, constraints and opportunities ...
    • Review Paper on ‘Garden Kits’ in Africa: Lessons Learned and the Potential of Improved Water Management 
      Merry, Douglas J.; Langan, Simon (IWMI; Texas &M University. Libraries, 2014)
      The purpose of this paper is to synthesize the available knowledge and lessons learned from past experiences in promoting kitchen or home gardens for food production, with a special emphasis on water management. The benefits ...
    • Suitability of Watershed Models to Predict Distributed Hydrologic Response in the Awramba Watershed in Lake Tana Basin 
      Moges, Mamaru A.; Schmitter, Petra; Tilahun, Seifu A.; Langan, Simon; Dagnew, Dessalegn C.; Akale, Adugnaw T.; Steenhuis, Tammo S. (Land Degradation & Development; Texas &M University. Libraries, 2016)
      Planning effective landscape interventions is an important tool to fight against land degradation and requires knowledge on spatial distribution of runoff. The objective of this paper was to test models that predict temporal ...
