effects of land use on soil moisture variations in a semi arid catchment implications for land and Agricultural Water Management
Land Degradation & Development, 2014Co-Authors: Xiaodong Gao, Xining Zhao, Juan Wang, Yinguang ShiAbstract:Knowledge of the effects of land use on soil moisture variations is necessary to improve land and Agricultural Water Management in the semi-arid Chinese Loess Plateau. However, previous studies are insufficient to guide Management practice in this area and improvement is needed to help with the development of the ‘Grain for Green’ programme. As part of the ‘Grain for Green’ programme, we examined the effects of five land uses (fallow, grassland, cropland, 3-year and 8-year jujube orchards) on soil Water variations in a small catchment on the Loess Plateau. Soil moisture at 0–160 cm depth was monitored approximately weekly at 47 sites from 17 August to 19 October 2009 and from 4 April to 27 September 2010 using a portable time domain reflectometer. Results indicated that mean soil Water profiles in different land uses varied with time, land use induced spatial variations of soil Water but exerted negligible influence on soil Water temporal patterns, and soil Water content was of the greatest spatial variability with moderate means (approximately 20 per cent). Furthermore, the relationship between standard deviation and mean Water content was dependent on soil depth, although it was negligibly affected by land use. Profile soil Water for five land uses was different in various seasons, precipitation infiltration depth exhibited a positive correlation with precipitation, and the whole profile soil moisture (0–160 cm) was complemented following a 93·5-mm rainfall event. The findings presented here provide helpful information for land and Agricultural Water Management in this area. Copyright © 2011 John Wiley & Sons, Ltd.

Mapping the potential success of Agricultural Water Management interventions for smallholders: Where are the best opportunities?
Water Resources and Rural Development, 2015Co-Authors: Jennie Barron, Eric Kemp-benedict, J. Morris, A. De Bruin, G. Wang, Amanda FenclAbstract:From field to basin scales, there are many appropriate interventions used to manage rainfall efficiently and productively in smallholder farming systems. Yet, successful targeting and scaling-out of these approaches remains a challenge. This paper presents an innovative approach in decision support called ‘Targeting Agricultural Water Management Interventions’ (TAGMI) with application in Limpopo and Volta river basins (available at http://www.seimapping.org/tagmi/). The online open-access TAGMI uses country-scale Bayesian network models to assess the likelihood of success for outscaling various Agricultural Water Management (AWM) interventions at sub-national level. The web tool integrates multiple sources of expertise on the enabling environment for outscaling based on key social, human, physical, financial, and natural factors. It estimates the relative probability of success of an AWM intervention across the Limpopo and Volta river basins. Here we present TAGMI as a ‘proof of concept’, areas of high, medium, and low probabilities of success for three AWM technologies common in Limpopo and Volta River Basins: the soil Water conservation/in situ rainWater harvesting technologies in rain-fed systems, small-scale private irrigation and small reservoirs used for communal irrigation purposes. We then apply a climate change scenario and discuss the robustness in potential AWM, according to the TAGMI tool. Finally, we discuss the need for generic or specific information on ‘best practices of implementation’ for successful uptake of technologies in poverty-constrained smallholder farming systems.

Setting up Agricultural Water Management interventions – learning from successful case studies in the Volta and Limpopo river basins
Water Resources and Rural Development, 2015Co-Authors: Annemarieke De Bruin, Jennie Barron, Rachel M. Pateman, Mariam Balima, Issa Ouedraogo, Evariste Constant Da Dapola, Mathias Fosu, F. O. Annor, M. S. Magombeyi, Jean-marie Kileshye OnemaAbstract:Abstract Long-term investments in Agricultural Water Management (AWM) interventions in the Volta and Limpopo river basins have aimed at improving Water availability and quality for smallholder farming systems. However, sustained and wider uptake of AWM technologies and approaches has not been as successful. We need to learn from successful AWM interventions, those interventions that have led to a sustained or increased uptake of AWM technologies or approaches, and which have led to improved well-being of farmers and livestock keepers in the rural development context of sub-Sahara Africa. This paper explores AWM interventions, specifically, the impacts these interventions have had and the factors contributing to the success of these interventions. In four countries within the Volta and Limpopo river basins, consultations were carried in 33 case studies of successful AWM interventions with implementing organisations and beneficiaries using a participatory GIS methodology. A systematic text analysis of 55 case study reports showed that these 33 interventions have had a positive impact on the well-being of beneficiaries and there was a sustained and wider uptake of the AWM technologies or approaches introduced. A clear demand for the technology, appropriate design of the technology, input support, training and capacity building, and a sense of ownership of the community helped to sustain the uptake of AWM technologies and approaches. We conclude that implementing organisations would benefit from investing in the soft components of an AWM intervention, as this will increase the likelihood of successful adoption and adaptation of the AWM technologies and approaches in the long-term.

Taking stock of forty years of Agricultural Water Management interventions in smallholder systems of Burkina Faso
Water Resources and Rural Development, 2014Co-Authors: Sabine Douxchamps, Augustine A. Ayantunde, Jennie BarronAbstract:Agricultural Water Management (AWM) strategies have been extensively studied and promoted in Burkina Faso during the past four decades. However, rainfall variability and Water access continue to limit Agricultural production of most of the smallholder farming systems of the country. Our goals in this paper are: (i) to review the evolution of AWM development with respect to the technologies promoted, while emphasizing the context, approaches, investments and outcomes; (ii) to explore the linkages between the evolution of AWM projects, their outcomes and their impacts on rural livelihoods; and (iii) to provide recommendations to enhance the impact of new development initiatives. Between 1970 and 2009, 195 bilateral and multilateral AWM projects were implemented in Burkina Faso, corresponding to an investment of US$ 641 million.The study of the evolution of these projects allows one to assess the reasons for their success or failure. While projects involved many technical solutions, their actual impact on livelihoods is debatable. Using an outcome–impacts framework, we provide recommendations for enhancing the effectiveness and sustainability of investments in Agricultural Water Management.

Participatory geographic information systems for Agricultural Water Management scenario development: A Tanzanian case study
Physics and Chemistry of The Earth, 2011Co-Authors: Steve Cinderby, Annemarieke De Bruin, Boniface Mbilinyi, Victor Kongo, Jennie BarronAbstract:Abstract One of the keys to environmental Management is to understand the impact and interaction of people with natural resources as a means to improve human welfare and the consequent environmental sustainability for future generations. In terms of Water Management one of the on-going challenges is to assess what impact interventions in agriculture, and in particularly different irrigation strategies, will have on livelihoods and Water resources in the landscape. Whilst global and national policy provide the overall vision of desired outcomes for environmental Management, Agricultural development and Water use strategies they are often presented with local challenges to embed these policies in the reality on the ground, with different stakeholder groups. The concept that government agencies, advocacy organizations, and private citizens should work together to identify mutually acceptable solutions to environmental and Water resource issues is increasing in prominence. Participatory spatial engagement techniques linked to geographic information systems (commonly termed participatory GIS (PGIS)) offers one solution to facilitate such stakeholder dialogues in an efficient and consultative manner. In the context of Agricultural Water Management multi-scale PGIS techniques have recently been piloted as part of the ‘Agricultural Water Management Solutions’ project to investigate the current use and dependencies of Water by small-holder farmers a Watershed in Tanzania. The piloted approach then developed PGIS scenarios describing the effects on livelihoods and Water resources in the Watershed when introducing different Management technologies. These relatively rapid PGIS multi-scale methods show promise for assessing current and possible future agriculture Water Management technologies in terms of their bio-physical and socio-economic impacts at the Watershed scale. The paper discusses the development of the methodology in the context of improved Water Management decision making.
