Institutions, impact synergies and food security: a methodology with results from the Kala Oya Basin, Sri Lanka by Saleth, Rathinasamy Maria, Dinar, A., Neubert, S., Kamaiah, B., Manoharan, S., Abayawardana, Sarath, Ariyaratne, Ranjith, de Silva, S. Pdf

The success of development programs depends on the role of underlying institutions and the impact synergies from closely related programs. Existing literature has limitations in accounting for these critical factors. This paper fills this gap by developing a methodology, which can quantify both the institutional roles in impact generation and the impact synergies from related programs. The methodology is applied to the Kala Oya Basin in Sri Lanka for evaluating the impacts of three development programs and 11 institutions on food security. The results provide valuable insights on the relative roles of institutions and the varying flow of impact synergies both within and across impact pathways.

Quantifying Institutional Impacts and Development Synergies in Water Resource Programs: A Methodology with Application to the Kala Oya Basin, Sri Lanka by R. Maria Saleth Pdf

The success of development programs, including water resource projects, depends on two key factors: the role of underlying institutions and the impact synergies from other closely related programs. Existing methodologies have limitations in accounting for these critical factors. This paper fills this gap by developing a methodology, which quantifies both the roles that institutions play in impact generation and the extent of impact synergies that flows from closely related programs within a unified framework. The methodology is applied to the Kala Oya Basin in Sri Lanka in order to evaluate the impacts of three water-related programs and the roles of 11 institutions in the context of food security. The results provide considerable insights on the relative role of institutions and the flow of development synergies both within and across different impact pathways. The methodology can also be used to locate slack in impact chains and identify policy options to enhance the impact flows.

Groundwater of South Asia by Abhijit Mukherjee Pdf

This book presents recent findings from the South Asian region (SA), broadly including groundwater studies on (a) quantity, (b) exploration, (c) quality and pollution, (d) economics, management and policies, (e) groundwater and society, and (f) sustainable sources. It offers a compilation of compelling, authentic insights into groundwater scenarios throughout the water-stressed South Asia region. Comprising Afghanistan, Bangladesh, Bhutan, India, Myanmar, Nepal, Pakistan, and Sri Lanka, it is the most densely populated region in the world: It occupies approximately 4% of the global land area but supports more than 25% of the global population. The SA region now faces an acute shortage of fresh water due to a rapid rise in water demand and changes in societal water-use patterns. Combining essential advances and perspectives, this book offers a valuable resource for all scientists, planners and policymakers who are interested in understanding and developing the SA and other related areas.

Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment by Raschid-Sally, L., Jayakody, P. Pdf

In 4 out of 5 cities in developing countries, wastewater is used to cultivate perishable crops for urban markets. Such practices create a health risk but provide important livelihood benefits. This study through an analysis of 53 cities in developing countries, contributes to understanding the factors that drive wastewater use. The main drivers are (1) increasing urban water demand without wastewater treatment causing pollution of irrigation water sources; (2) urban food demand favoring agriculture close to cities where water sources are polluted; and (3) lack of cheaper, similarly reliable or safer water sources. Poverty, which constrains the infrastructure needs of urbanization, is an added factor. The study makes policy recommendations stressing on, effectively applying the WHO guidelines, linking investments in water supply with sanitation for maximum beneficial impact on water pollution, and involving actors at both the national and local level, for water quality improvements and health risk reduction

Implementing Integrated River Basin Management by François Molle,Thai Hoanh Chu Pdf

The report focuses on the establishment of the Red River Basin Organization (RRBO) in Vietnam, but expands its analysis to the wider transformations of the water sector that impinge on the formation and effectiveness of this organization. A few reflections on the policy process are drawn from this analysis, albeit in a tentative form given the relatively limited period of time considered here. The report shows that the promotion of IWRM icons such as RBOs by donors has been quite disconnected from the existing institutional framework. However, the establishment of RBOs might eventually strengthen a better separation of operation and regulation roles. Institutional change is shown to result from the interaction between endogenous processes and external pressures, in ways that are barely predictable.

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia by Kim, U., Kaluarachchi, J. J., Smakhtin, V. U. Pdf

The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Mapping drought patterns and impacts: a global perspective by Nishadi Eriyagama,V. Y. Smakhtin,Nilantha Gamage Pdf

The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

Economic gains of improving soil fertility and water holding capacity with clay application: the impact of soil remediation research in northeast Thailand by Saleth, R. M., Inocencio, A., Noble, A. D., Ruaysoongnern, S. Pdf

Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44 for the sample, and a NPV of US$21 million with a BCR of 75 for the region.

Adaptive water resource management in the South Indian Lower Bhavani Project Command Area by Lannerstad, M., Molden, D. Pdf

This report explores the theory and practice of Adaptive Water Management (AWM) based on a detailed field study in the Lower Bhavani Project (LBP) in the South Indian state of Tamil Nadu. A five-step framework is used to analyze the extent to which AWM is practiced and how it could be improved. The analysis shows that the LBP system has increasingly fulfilled the criteria of a complex adaptive system over the years. The main uncertainty factor, rainfall variability, has been considered in a stepwise way during the system change cycles and has been included in the LBP system design. The study shows that in spite of contending with an imperfect irrigation system design and intense competition for water resources, water resource managers and farmers are able to adapt and continue to reap benefits from a productive agricultural system.

Importance of irrigated agriculture to the Ethiopian economy: capturing the direct net benefits of irrigation by Fitsum Hagos,Makombe, Godswill,Namara, Regassa E.,Awulachew, Seleshi Bekele Pdf

Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.

Evaluation of current and future water resources development in the Lake Tana Basin, Ethiopia by McCartney M. , Alemayehu T. , Shiferaw A. , Awulachew S. Pdf

Lake Tana, located in the headwaters of the Blue Nile, is valuable for many people including the communities who live around the lakeshore and those who live immediately downstream. The area has been identified as a region for hydropower and irrigation development, vital for economic growth in Ethiopia. A multidisciplinary study was conducted to assess the possible impacts of this development. This study found that current development has benefited some local people but adversely affected others. Future development will exacerbate pressure on the lake. Hard choices must be made about how the water is best utilized. It is important that all stakeholders, including local people, are involved in the decision-making process.

The lower Krishna Basin trajectory: relationships between basin development and downstream environmental degradation. by Anonim Pdf

Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated natural resources management from the local to the basin level are needed too.

Malaria transmission in the vicinity of impounded water: evidence from the Koka Reservoir, Ethiopia by Solomon Kibret,McCartney, Matthew,Lautze, Jonathan,Jayasinghe, G. Pdf

The construction of dams in Africa is often associated with adverse malaria impacts in surrounding communities. However, the degree and nature of these impacts are rarely quantified and the feasibility of manipulating reservoir water levels to control mosquito breeding has not been previously investigated in Africa. This report describes entomological and epidemiological studies conducted around the Koka Dam and Reservoir in Ethiopia. The research findings confirm the role of the reservoir in increasing malaria transmission and provide evidence that there is potential to use dam operation in integrated malaria control strategies.
