Impact evaluation of community-based coastal resource management projects in the Philippines

The benefits of decentralizing the management of coastal resources to local governments and resource users have long been recognized, but the best systems for coastal resources management depend on many factors. A number of community-based management and co-management projects were started in the Philippines in the early 1980s. This report describes a comparative assessment of these projects to determine where improvements can be made in the design of future community-based coastal resource management projects. Early and continuing involvement by project beneficiaries is one of the factors that contributes to the success of the project development, implementation, and evaluation.

Strengthening impact evaluation in natural resource management

The workshop on Strengthening Evaluation in Natural Resource Management Research is part of an ACIAR-funded Small Research and Development Activity (SRA) on Assessing the Impacts of Natural Resource Management and Policy Research in Development Programs, with WorldFish and Commonwealth Scientific and Industrial Research Organization (CSIRO) as partners. The SRA objectives included a review of literature to identify challenges in assessing the impact of NRMR programs and to propose a framework that addresses them. An exploratory workshop was held in February 2012 to initiate collective action within the CGIAR Research Programs (CRPs) to identify and address their impact challenges and led to the creation of the NRMR impact community of practice (COP). This follow-up workshop brought together members of the COP and partners in the SRA to discuss and reach agreement on how to progress on our collective goals of building new and appropriate approaches for NRMR IE and how to put these approaches into action through our research programs. This report is a documentation of the workshop process and outputs.

A practical guide for ex-ante impact evaluation in fisheries and aquaculture

This guide provides a framework for ex-ante evaluation of fisheries and aquaculture projects in developing countries. Ex-ante impact evaluations check the potential of a project or program to deliver benefits from proposed interventions. Providing extensive annotated literature citations, this guide is designed for use by practitioners who may not be fisheries or aquaculture specialists. The guide uses concepts from results-based management, organized into five modules that structure the investigation and provide insights regarding alignment of the proposed intervention with stakeholder interests, feasibility of design, potential constraints to implementation, possible impact pathways and distributional effects of the intervention. Separately published case studies of investments in Bangladesh, Malawi and Ghana illustrate application of the guide.

Ex-ante impact evaluation: case studies from Malawi, Bangladesh and Ghana

This document presents ex-ante impact evaluations of research for development projects related to aquaculture in Bangladesh, Malawi and Ghana. The Ghana chapter also includes an ex-ante evaluation of a fisheries project. The case studies utilized preliminary versions of guidelines developed specifically for ex-ante evaluations of aquaculture and fisheries projects. The guidelines, found in A Practical Guide for Ex-Ante Impact Evaluations in Fisheries and Aquaculture, are designed to provide an approach for a qualitative examination of the potential for a project to deliver impacts. Using a conceptual framework based on the outcome focus of results-based management, the guidelines stress careful examination of the setting, internal consistency, a sound theory of change, and an examination of stakeholders’ interests and potential partnerships. The case study reports illustrate the variability with which the guidelines may be interpreted and applied. The different teams, operating with limited time and budget that constrained the collection of new data, were forced to utilize existing secondary data and information and consult with key stakeholders to complete their analyses. The varying levels of reporting reflect the differences among the cases in the amounts of existing information and variety of stakeholders potentially involved in the projects being examined.

Cypermethrin use in forestry and its impact on Welsh streams: An evaluation of the impact of cypermethrin use in forestry on Welsh streams

This is the Evaluation of the impact of cypermethrin use in forestry on Welsh streams from the University of Plymouth, published on September 2010 by the Environment Agency South West. The report focuses attention on Cypermethrin, a highly active synthetic pyrethroid insecticide effective against a wide range of pests in agriculture, public health, and animal husbandry. It is also used in forestry to control the pine weevil, Hylobius abietis. Cypermethrin is very toxic to aquatic invertebrates and fish at nanogram per litre concentrations. This project checks the effectiveness of current best practice measures in minimising the risk of pollution associated with the use of cypermethrin in forestry in Wales. Chemical results from the intensive studies show that cypermethrin entered minor watercourses draining treated areas at two of the eight sites. In one of these cases the level was well in excess of the short-term Predicted No Effect Concentration. The absence of a buffer area at the other site resulted in the cypermethrin reaching a main drain. However dilution appeared to be sufficient to prevent any impact on water quality or on the invertebrate community in the main stream. Invertebrate and chemical data from the extensive survey showed little evidence of pollution due to wider use of cypermethrin in Welsh forestry. Finally, a number of recommendations are made for further tightening controls on forestry practice to minimise the risk of cypermethrin entering the aquatic environment.

An evaluation of the pelagic primary productivity and potential fish yield of Kainji Lake, Nigeria

The environmental conditions of Kainji Lake from 1971/72 to date appear to have stabilized to a large extent, judging from the similarity of physico-chemical parameters investigated in this study over the period. Solar radiation (as reflected in variation in temperature) and pH have remained largely constant over the years, while conductivity (index of nutrient enrichment), though significantly higher in 1995/96, could be described as sporadic and needs further monitoring to ascertain its trend in the lake. While water transparency and dissolved oxygen were higher in 1971/72 compared to the other years, these increases cannot be said to be overwhelming. The lower transparency in 1995/96 was due to the exceptional flood of that year and may have also accounted for the poorer dissolved oxygen concentration compared to the other years due to its impact on photosynthesis. There is no evidence from this study to indicate that primary productivity has increased over the years. Consequently, the observed increase in fish yield by the KLFPP from CAS, which is corroborated by estimates from the MEI, cannot be supported on the basis of improved photosynthetic production. The phenomenal high levels of conductivity recorded during certain periods in 1995 (600 mu mhos cm super(-1)) are hitherto unknown in the lake and may indicate a trend towards nutrient enrichment. However, it is premature at this stage to conclude on its long-term impact on primary production and consequently, on fish yield. Secondly, the notion of overfishing in the 80s (Ita, 1993), may need to be further examined as low or dwindling catches could be due to a number of factors among which are the level of fishing effort, the type and efficiency of gears and the intensity of sampling. It would appear that with the intervention of KLFPP, the better management of the lake's fisheries would increase the current level of catch. It also needs to be examined how much of the clupeid fisheries, which is now known to account for a substantial proportion of the total fish yield in Kainji Lake, was included in the sampling of the 80s.

Coastal resource planning system: Integrating evaluation of ecological integrity and ecosystem services valuation

Efficient and effective coastal management decisions rely on knowledge of the impact of human activities on ecosystem integrity, vulnerable species, and valued ecosystem services—collectively, human impact on environmental quality (EQ). Ecosystem-based management (EBM) is an emerging approach to address the dynamics and complexities of coupled social-ecological systems. EBM “is intended to directly address the long-term sustainable delivery of ecosystem services and the resilience of marine ecosystems to perturbations” (Rosenberg and Sandifer, 2009). The lack of a tool that integrates human choices with the ecological connections between contributing watersheds and nearshore areas, and that incorporates valuation of ecosystem services, is a critical missing piece needed for effective and efficient coastal management. To address the need for an integrative tool for evaluation of human impacts on ecosystems and their services, Battelle developed the EcoVal™ Environmental Quality Evaluation System. The EcoVal system is an updated (2009) version of the EQ Evaluation System for Water Resources developed by Battelle for the U.S. Bureau of Reclamation (Dee et al., 1972). The Battelle EQ evaluation system has a thirty-year history of providing a standard approach to evaluate watershed EQ. This paper describes the conceptual approach and methodology of the updated EcoVal system and its potential application to coastal ecosystems. (PDF contains 4 pages)

Assessment of the impact of aquatic resources research by ICLARM: scope and methodologies

The importance of quantifying the economic returns to investments in aquatic resources research together with the social, environmental and institutional impacts of such investments is widely recognized among ICLARM's donors, trustees and beneficiaries. As with other Consultative Group on International Agricultural Research (CGIAR) centers, ICLARM is being asked to provide specific accounts of the outputs of its research and their impact on farms and on fisheries, including their socioeconomic impact. Such impact information has become a necessary, though not sufficient, basis for setting priorities and allocating resources for research for the CGIAR centers. This paper discusses the types and methods of impact assessment relevant to ICLARM's work. A three-pronged assessment approach is envisaged to capture the full range of impacts: 1) ex ante assessment for research priority setting; 2) assessment prior to dissemination or adoption along with monitoring and evaluation; and 3) ex post impact assessment. It also discusses the objectives and scope for operational impact assessment of ICLARM's research.
