This paper is the first in a series of three interrelated papers and focuses on planning and implementation modalities of Rainwater Management (RWM) Strategies. It is part of the NBDC project ‘On integrated RWM strategies—technologies, institutions and policies’. The project is underpinned by the recognition that integrated RWM needs to combine technologies, policies and institutions and be developed through multi-stakeholder engagement to foster innovation. Three woredas were selected for the research—Jeldu and Diga in Oromia Region and Fogera in Amhara Region.

The hydrology of Holetta River and its seasonal variability is not fully studied. In addition to this, due to scarcity of the available surface water and increase in water demand for irrigation, the major users of the river are facing a challenge to allocate the available water. Therefore, the aim of this research was to investigate the water availability of Holetta River and to study the water management in the catchment. Soil and Water Assessment Tool (SWAT) modelled the rainfall runoff process of the catchment.

Using a multi-criteria optimization technique for system analysis, this paper quantitatively characterizes baseline production activities, resource management and environmental relationships of the mixed crop–livestock farming system at the Jaba micro-watershed, upper Blue Nile Basin, to get insights that inform sustainable intensification of small-scale agriculture.

The quantity and position of trees in a landscape can have significant impacts on farm soil and water resources. Here we present a synthesis of local knowledge studies conducted in three micro-catchments of the Blue Nile Basin (Diga, Fogera and Jeldu Woredas) exploring natural and anthropogenic drivers of tree cover change. In total more than 90 purposively selected farmers were interviewed, whilst focus group discussions and feedback sessions were held with larger groups.

Understanding the basic relationships between rainfall, runoff, soil moisture and ground water level are vital for an effective and sustainable water resources planning and management activities. But so far there are no hydrological studies in Meja watershed that aims to understand the watershed characteristics and runoff generation processes. This study was conducted to understand runoff generation processes and model rainfall runoff relationship in Meja watershed having a drainage area of 96.6 km2.

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.

Restrictive soil layers commonly known as hardpans restrict water and airflow in the soil profile and impede plant root growth below the plough depth. Preventing hardpans to form or ameliorate existing hardpans will allow plants root more deeply, increase water infiltration and reduce runoff, all resulting in greater amounts of water available for the crop (i.e. green water).

In the Blue Nile basin, crop cultivation is predominantly rainfed and water availability is highly variable across both space and time. As a result, it often constitutes a limiting factor for reaching full agricultural potential in the region. While one third of the basin is estimated to have no soil moisture limitations, the remaining two thirds are crop water constrained in various ways. Analysis shows that across approximately 40% of the basin available soil moisture is utilized sub-optimally with smart management and crop water limitations can be alleviated.

La semana pasado CONDESAN estuvo presentando nuestra experiencia, vinculada a los mecanismos para compartir beneficios en cuencas hidrográficas, a través de una presentación a cargo de Bert De Bievre, Coordinador del Área de Cuencas Andinas, en el Seminario Taller Internacional de Cultura del Agua organizado por la Secretaría del Agua del Ecuador; a través de la Dirección Nacional de Cultura y en coordinación con la Red Latinoamericana de Centros del Conocimiento en Gestión de Recursos Hídricos (RALCEA).

The Challenge Program on Water and Food (CPWF) Phase II for the Limpopo Basin Development Challenge (LBDC) project aims to develop methods, processes, and technologies to help resource- constrained smallholder farmers mitigate poverty and food insecurity through improved agricultural water management (AWM) strategies.
