AbstractWater adequacy is central to maximised agricultural production in irrigation schemes. Smallholder Irrigation Schemes (SISs) are designed to distribute water efficiently, adequately and equitably. Water governance, defined as the institutions, processes, procedures, rules and regulations involved in water management, plays an important role in water allocation and subsequently water adequacy. The intersectoral institutions involved in water governance in SISs, i.e., government, Water User Associations (WUAs), Irrigation Management Committees (IMCs) and traditional authorities, interact to formulate and design policies for running SISs. However, multilevel interaction amongst the active stakeholders at multiple levels shapes policy and underlies SIS performance. This research aimed to investigate the impacts water governance had on adequacy of water in irrigation schemes and was premised on the hypothesis that governance had no effect on water adequacy. Water adequacy describes water supply relative to demand. Adequacy indicates whether the water delivery system supplies the required amount to a section in the irrigation scheme over a period of time (daily, monthly or seasonally). Two irrigation schemes, the Mooi-River Irrigation Scheme (MRIS) and Tugela Ferry Irrigation Scheme (TFIS) were used as case studies. A descriptive analysis showed that 86% of the farmers in the TFIS had adequate water, whereas 24% had water adequacy in the MRIS. A Binary Logit model was employed to investigate the factors that influence water adequacy among irrigators. The regression model identified eight statistically significant factors that influenced water adequacy: the irrigation scheme, location of plot within the scheme, training in water management, training in irrigation, SIS irrigators' knowledge about the government's aims, availability of water licences, payment of water fees and satisfaction with the irrigation schedule. The study concluded that governance factors had influence on water adequacy in the selected SISs. The implication is that stakeholders should make irrigators aware of government Irrigation Management Transfer (IMT) policy and strategies. The study recommends that the SISs introduce rules, procedures and protocols to support irrigators to enhance scheme governance and lead to the realisation of government policies.

A pilot study, using a co-innovation approach in identify opportunities to improve irrigation management, is underway in five farms in an irrigation scheme in New Zealand. Through a process of co-learning, a group of on-farm and off-farm stakeholders defined the problem of on-farm water use efficiency and co-developed solutions to enhance farmers’ ability, desire and capacity to adopt improved irrigation practices. To enable informed decision-making, participants were supplied with current soil water demand (measured on farm) and 2- to 15-day rainfall forecasts as a daily email update. We conducted several one-on-one formal/informal meetings and annual workshops with stakeholders to evaluate the farmers’ ability in integrating the updates into their current irrigation practices. Selected key findings were (i) on-farm irrigation decisions are influenced by on-farm and off-farm hydrological, climatic, infrastructural and regulatory factors, thus we need to develop a wider view to irrigation management, (ii) for successful uptake, it is important to understand the external stimuli that directly and indirectly conflict or align with proposed practice changes, (iii) introduction of stakeholders with conflicting perspectives needs to be carefully managed, (iv) with co-learning, project objectives continuously evolve in response to ongoing monitoring, review and reflection on the processes, thus it is important to build flexibility into the implementation pathway and (v) when scaling out from five farms to the wider irrigation scheme, opportunities such as collective learning and reflection at end-user focused workshops may become more challenging owing to stakeholder numbers, thus other co-learning opportunities need to be identified.

<p>Investigations carried out under the MOSESH2020 project in the Doukkala irrigation scheme (western Morocco) allowed the generation of several data products during the agricultural seasons 2016-2017 and 2017-2018: Seasonal probabilistic weather forecast, Early-season and In-season crop mapping, Monitoring of crop water demand and Short-term forecasts of irrigation water requirements.</p><p>This study was focused on the assessment of the adequacy of the water applied to meet the crop water demand in the two irrigation seasons 2016-2017 and 2017-2018.</p><p>Monitoring of Crop Water Demand (CWD) was based on the estimation of the maximum crop evapotranspiration, obtained from remote sensing data of the monitored area. Such output is updated frequently (e.g. every week) during the irrigation season and compared to the weekly surface irrigation water volumes allocated. Although the assessment of adequacy of allocations against the crop water demand (CWD) showed that the latter was much larger with 10-15% than allocated surface water for the entire area, with this difference being small at the beginning of the growing season.</p><p>The use of MOSES products during the irrigation management operations would help the water management authority to save water, especially during the winter season, leaving additional water available to meet requirements in spring and summer.</p>

AbstractIn the era of climate change, irrigation is playing a pivotal role in stabilising food production, enabling dry season farming, and improving farmers’ livelihoods, particularly in Asia and African countries. Recently, Ghana has taken steps to respond to the concept of stakeholder collaboration to improve the irrigated agricultural sub-sector as well as enhance farmers’ resilience to changing climate. However, there is limited attention to recent diverging experiences on collaborative practices from irrigation stakeholders. Using the Weija Irrigation Scheme as a case study, this study explores stakeholders’ perceptions of collaborative practices in irrigation management by identifying gaps and providing suggestions to enhance stakeholder collaboration. We conducted focus group discussions with farmers and in-depth interviews with key informants, such as heads of farmer groups, government departments, agencies, and agricultural extension agents. Secondary data from conventional literature, organisational websites, and quarterly reports were also used. Following the integrated collaboration governance theory, effective collaboration was measured based on the tripartite prism of “principled engagement, shared motivation, and capacity for joint action”. Analysis of the data reveals that despite the central government’s resolve for collaborative irrigation planning and management, effective collaboration remains limited. Based on principle engagement, this study points out  that weak communication and sharing of information remain in the planning and management of the Weija Irrigation Scheme. In terms of shared motivation, there were minimal commitment to joint project planning, exclusion of some key stakeholders from meetings, and negative attitudes towards collaboration. Finally, the capacity for joint action (e.g. lack of fund, time, staff, and equipment) is limited. The policy implications and suggestions for further research are presented in the study.

ABSTRACTIn order to explore the conditions for successful communal irrigation management, this study investigates the determinants of household contributions to the cleaning of irrigation channels and the availability of water. By using household-level data collected in a large-scale gravity irrigation scheme in Uganda, whose management was transferred from the government to the community, we find that household contributions to the cleaning of irrigation channels are determined by the scarcity of irrigation water, the opportunity cost of labor and the private benefit associated with plot size. We also find that the availability of irrigation water increases in the tertiary irrigation canal where the coefficient of variation of plot size is large, which may indicate that farmers of larger plots are particularly active in water management. These findings suggest that farmers are responsive to private benefits and, hence, the support of the government for communities to implement punishment may be effective for successful irrigation management.

Sendo assim o objetivo do presente trabalho foi avaliar a absorção de macronutrientes e sódio pela cultura do tomate irrigado com e sem déficit hídrico, utilizando água residuária. O experimento foi conduzido em ambiente protegido, o sistema de irrigação foi por gotejamento, e o manejo da irrigação foi baseado na evaporação do tanque classe ‘A’ instalado dentro do ambiente. Foram determinadas duas lâminas: 70 e 100% da evapotranspiração da cultura, nas quais foram utilizadas água de abastecimento e de esgoto doméstico tratado em quatro diluições: 25, 50, 75 e 100%. Assim, foi possível avaliar a absorção de macronutrientes e sódio, na área foliar e frutos, através de análise química. Os resultados obtidos, indicaram que as plantas irrigadas com déficit hídrico absorveram maior quantidade dos nutrientes N, K, Mg e S. No entanto quanto maior a porcentagem de água residuária na irrigação, maior foi a absorção de sódio pelas plantas e frutos.   Palavras chave: nutrição, reúso doméstico, manejo da irrigação, Lycopersicon esculentum L.     SOUSA, F.

ABSORPTION OF MACRONUTRIENTS AND SODIUM BY TOMATOES SUBMITTED TO NORMAL AND WATER DEFICIENT IRRIGATION SCHEMES USING VARIOUS CONCENTRATIONS OF WASTEWATER       2 ABSTRACT   The high worldwide demand for water use in economic development and domestic consumption has led to studies on the agricultural use of wastewater that can help minimize the problem of scarcity of this resource. This study aimed to evaluate the absorption of macronutrients and sodium from cultivated tomatoes, irrigated with wastewater, under normal and water deficient irrigation schemes. The experiment was conducted in a greenhouse, we used a drip irrigation system that was managed on the basis of evaporation from a Class A tank placed in the experimental area. Two irrigation depths were determined: 70 and 100% of the crop evapotranspiration, supply water, and four dilutions of domestic wastewater were used: 25, 50, 75, and 100%. We evaluated the absorption of macronutrients and sodium via chemical analysis of the leaves and fruits. Results showed that plants irrigated using the water deficit irrigation scheme absorbed more N, K, Mg, and S nutrients. However, the higher the percentage of wastewater used for irrigation, the higher the absorption of sodium by plants and fruits.   Keywords: nutrition, domestic reuse, irrigation management, Lycopersicon esculentum L.
