Forests, water and mixed land use mosaics in developing countries: making research solutions effective by Spilsbury, M.J.

“…It highlights some of the key constraints to the utilisation of existing knowledge. Hydrological processes may be well understood at a plot level, or for a single particular land use/landcover type at a catchment scale but become more uncertain at larger spatial scales or at smaller scales where the same processes operate across multiple land uses and management regimes. …”

Improved water and land management in the Ethiopian highlands and its impact on downstream stakeholders dependent on the Blue Nile by Awulachew, Seleshi Bekele, Ahmed, A.A., Haileselassie, A., Yilma, Aster Denekew, Bashar, K.E., McCartney, Matthew P., Steenhuis, Tammo S.

“…This project was envisaged to improve the scientific understanding of the land and water resources of the basin, and hypothesized that with increased scientific knowledge of the hydrological, watershed, and institutional processes of the Blue Nile in Ethiopia (Abbay), constraints to up-scaling adaptable best practices and promising technologies (technical, socio-economic, institutional) could be overcome, which will result in significant positive impacts for both upstream and downstream communities and state.…”

River-basin planning and management: the social life of a concept by Molle, Francois

“…Associated with utopian ideas of the late 19th century, it supported ideas of full control of the hydrologic regime and multipurpose dam construction in the 1930-1960 period, then partly faded and was revived to address water-quality problems, before reemerging in the 1990s as the cornerstone of Integrated Water Resources Management (IWRM), enriched and blended with watershed- and ecosystem-management approaches. …”

Soil structure and glyphosate fate under no-till management in the Pampa region. I. Soil structural anisotropy and hydro-physical behavior by Behrends Kraemer, Filipe, Sainz, Daiana Soledad, Morras, Héctor José María, Carfagno, Patricia, Eiza, Maximiliano Joaquin, Fernandez, P., Chagas, Celio Ignacio

“…Total porosity, pore size and type and orientation of aggregates and pores appeared to be the main factors explaining the slow infiltration and the great variability of hydrological parameters. The results obtained indicate that a detailed study of structure and porosity of soils cultivated under NT can help to evaluate the effects of this practice on their physical health and behavior.…”
