Country strategy paper: Philippines

The Philippines rank 85 out of 175 countries in terms of Human Development Index. Poverty is most acute and widespread in rural areas, including many coastal municipalities, where 54% of people are living below the poverty line. Dependence on coastal and inland aquatic resources is high among rural poor people, who tend to be self-employed, primarily in agriculture, fisheries and casual labor. They are almost all landless.

STREAM Country Strategy Paper: Sri Lanka

In Sri Lanka the incidence of poverty varies among regions and livelihoods; aquatic resources users represent a poor category in many regions and therefore a vulnerable group. In December 2004 the country was hit by a Tsunami originating off the coast of Aceh in Indonesia, which affected the livelihoods of a large section of coastal aquatic resource users. The country is currently engaged in a major humanitarian effort to improve the livelihoods of aquatic resources users through various donor-funded projects. (PDF contains 18 pages)

STREAM Country Strategy Paper: Vietnam

Vietnam is a coastal country in Southeast Asia with a population of over 80 million. Although Vietnam has long been listed among the poorest countries of the world, it has recently made large strides in reducing poverty and improving food security. However, the dramatic gains in poverty reduction in Vietnam still remain quite fragile. There is growing evidence to indicate that dependence on aquatic resources is correlated to poverty, and that aquatic resources constitute an important component of wider livelihoods strategies (largely from the Mekong Delta, Central Coast and the Northern Mountains).

Assessment of phytostabilization of Pb/Zn mine soils with organic amendments and a native metallicolous ecotype of Festuca Rubra l.: implications for amendment selection and recovery of soil health

La contaminación del suelo es una de las principales amenazas para los ecosistemas y la salud humana. Actualmente, desde un punto de vista tanto económico como ambiental, la fitoestabilización es la mejor tecnología para remediar suelos contaminados con elevadas concentraciones de metales como son los suelos mineros. La fitoestabilización asistida consiste en el empleo de plantas y enmiendas orgánicas y/o inorgánicas con el fin de reducir la movilidad y la biodisponibilidad de los contaminantes y recuperar la salud de suelo. En este trabajo se han realizado ensayos en microcosmos y en campo centrándonos en la salud del suelo minero contaminado con Pb y Zn durante un proceso de fitoestabilización empleando enmiendas orgánicas (purines vacunos, gallinaza, estiércol de oveja y lodos de papelera mezclados con gallinaza) y/o la especie metalífera Festuca rubra con el objetivo de (i) estudiar las interacciones suelo-enmienda responsables de los cambios inducidos por el proceso de quimioestabilización en las propiedades físicoquímicas y biológicas del suelo, (ii) evaluar la efectividad del proceso de fitoestabilización sobre suelos vegetados y de la revegetación sobre suelos desnudos (iii) valorar la idoneidad de distintos indicadores químicos y biológicos (parámetros microbianos y de la vegetación) para monitorizar la efectividad de la fitoestabilización asistida en términos de reducción de la biodisponibilidad de metales en el suelo, mejora de la vegetación y de la recuperación de la salud del suelo. La aplicación de enmiendas al suelo minero supone una entrada de materia orgánica y nutrientes que conduce a una disminución de la biodisponibilidad de metales, facilitando la colonización de las plantas y el crecimiento de la vegetación nativa, además de estimular la actividad microbiana del suelo. El pH del suelo es un factor crítico que condiciona la movilidad de los metales y la toxicidad del suelo. Las poblaciones microbianas de las enmiendas no modificaron la diversidad funcional de las comunidades microbianas nativas de la mina. Los purines vacunos y los lodos de papelera mezclados con gallinaza son los tratamientos más efectivos en el proceso de fitoestabilización asistida bajo condiciones de campo. La gallinaza fue el tratamiento que más estimuló el crecimiento de la vegetación nativa y la colonización en los suelos desnudos. El bioensayo de elongación radical de lechuga es un test sensible, sencillo y barato para evaluar la biodisponibilidad de metal y la ecotoxicidad del suelo. Los tocoferoles son biomarcadores de exposición a metales con potencial para su implementación en bioensayos de toxicidad. Este trabajo permite concluir que la población metalífera de F. rubra, combinada con enmiendas orgánicas, es una excelente candidata para los proyectos de fitoestabilización asistida. Además, la monitorización simultánea de los parámetros fisicoquímicos y microbiológicos del suelo y de su ecotoxicidad permite una evaluación adecuada de la salud del suelo, así como la selección de enmiendas apropiadas para el desarrollo de un proceso fitoestabilizador.

Knowledge Exchange Discussion paper on Open Knowledge

The development of an openly available layer of scholarly and scientific content requires access to all types of output from the scholarly and scientific process. Interoperable and sustainable infrastructure components are invaluable elements and the content should be clearly licensed for re-use. Open Knowledge will improve the discoverability and re-usability of content across the sectors, to the benefit of higher education and research and will help the (European) knowledge economy to move forward. In Autumn 2013, scoping sessions took place with experts to discuss their views around the value of making knowledge open and the steps which need to be taken to achieve this. These discussions are collected in the Knowledge Exchange discussion paper on Open Knowledge.

Paper unemployment: the irish experience

When asked to give a paper at this conference I choosee "Incentive to encourage youth employment" but very soon into my research I felt that the overall approach to unemployment by succesive Irish Governments offered more valuable insights into this serious problem and the lack of recognition of how serious this problem is. This is particulary so for small economies and regions on the periphery of the EU.

Effects of the Cessation of Sewage Sludge Dumping at the 12-Mile Site: Proceedings of the 12-Mile Dumpsite Symposium, Ocean Place Hilton Hotel, Long Branch, New Jersey, 18-19 June 1991

This study owes its inception to the wisdom and experience of the staff of the Northeast Fisheries Science Center who, after several decades of surveys in the New York Bight, recognized a unique opportunity to capitalize on the decision to stop ocean dumping of sewage sludge and designed an innovative field study to evaluate effects on living marine resources and their habitats. For decades ocean dumping was viewed as a cheap and effective means for disposal of wastes generated by urbanized coastal areas. Even after the 12-mile site was closed, sewage sludge continued to be dumped at Deepwater Dumpsite 106. The 6-mile site off the NewJersey coast is still used as a dumpsite for dredged material from New York Harbor areas. Discussions continue on the propriety of using the deep ocean spaces for disposal of a variety of material including low level radioactive wastes. Consequently, managers are still faced with critical decisions in this area. It is to be hoped that the results from the 12-mile study will provide the necessary information on which these managers can evaluate future risks associated with ocean waste disposal.

Assessing the sustainability of brackish water aquaculture systems in the Phillipines. Working Paper 1: A typology of brackish-water pond aquaculture systems in the Philippines

Aquaculture in the Philippines is a long-standing activity but has witnessed relatively recent, rapid, technical change with the introduction of hatchery technology and commercial feed-mills changing the production possibilities for a fishpond operator. We are confronted with a diversity of aquaculture practices in the coastal areas of the Philippines, with new technologies being incorporated into more traditional systems. As a first step to understanding the sector, we therefore present a typology of farming systems with the motivation of generating domains (farm “types”) over which we can compare performance on a number of indicators. Our typology, restricted to brackish-water pond systems, is constructed using multivariate methods (principal components analysis, cluster analysis). Eight variables are used relating to the management of the farm across all the major factors of production. A stratified net sample of 136 observations provides the data for the analysis, from a farm-level survey carried out between January and June 2003 in the two main brackish-water production regions in the Philippines. We define five farm types from this analysis. In later work we will show how the use of this typology can be used for comparative study of economic, social and ecological performance at the farm-level. [PDF contains 42 pages]

Assessing the sustainability of brackish water aquaculture systems in the Philippines. Working Paper 4: Aquaculture and poverty - a case study of five coastal communities in the Philippines

After reviewing the rather thin literature on the subject, we investigate the relationship between aquaculture and poverty based on a case study of five coastal communities in the Philippines. The analysis relies on a data set collated through a questionnaire survey of 148 households randomly selected in these five communities. The methodological approach combines the qualitative analysis of how this relationship is perceived by the surveyed households and a quantitative analysis of the levels and determinants of poverty and inequality in these communities. There is overwhelming evidence that aquaculture benefits the poor in important ways and that it is perceived very positively by the poor and non-poor alike. In particular, the poor derive a relatively larger share of their income from aquaculture than the rich, and a lowering of the poverty line only reinforces this result. Further, a Gini decomposition exercise shows unambiguously that aquaculture represents an inequality-reducing source of income. We believe that the pro-poor character of brackish water aquaculture in the study areas is explained by the fact that the sector provides employment to a large number of unskilled workers in communities characterized by large surpluses of labour. Our results also suggest that the analysis of the relationship between aquaculture and poverty should not focus exclusively on the socio-economic status of the farm operator/owner, as has often been the case in the past.

The UNDP/FAO supported Federal Fisheries Project for the Development of Artisanal and Inshore Fisheries in Nigeria has the specific objective of increasing fish production through an integrated approach aimed at upgrading the rural coastal fishermen and improving their living conditions. The project has an operating life-span of three years and envisages a total outlay of nearly N3 million in terms of personnel and services. This paper attempts to review the activities of the project during the first two years of the operational phase and highlight some of its specific achievements.

A review paper on Integrated Aquaculture Benefits Project at Federal College of Forestry, Ibadan

This paper highlights some of the practices involved in integrated aquaculture such as poultry-cum-fish, pig-cum-fish, sheep and goat-cum-fish and grasscutter-cum-fish. Also the role of fisheries in alleviating protein deficiency was reviewed. Successful research findings on these practices in aquaculture at the Federal College of Forestry, Jericho, Ibadan (Nigeria) will eventually lead to alleviating protein deficiency of the inhabitants of the largest city in West African thus alleviating poverty in the nation

Review paper on the production trials of rice-cum fish culture - a transferable concept into Niger State, Nigeria

This paper reviews the production trials of rice-cum-fish culture. Rice and various fish species using rotation and concurrent methods of cultivation are used. The farming system is mostly practiced and researched in to in Southeast Asian countries. It addresses the problems of high external inputs, sustainable aquaculture, poverty and nutrition in the rural population, insect pests, use of insecticides, weeds control and under-utilization of agricultural lands. The production trials yields are summarized and a summary of annual income per hectare from rice and fish have been given. The yield however depends to a large extent on the species stocked, culture period, fertility of the soil and water, degree of supplemental feeding and culturing methods. The production results are discussed. Niger state is blessed with abundant wetlands/rice fields suitable for the practice. However, ecological differences from country to country and region to region, research and development trials are necessary to ensure a successful adoption of the technology to farmers in the State

Environmental impact assessment of agrochemicals for fish production - a review paper

The environmental impact of agro-chemicals for fish production was extensively reviewed. The positive contribution of agro- chemicals and the devastating effect on aquaculture was x-rayed to alert users to this obvious environmental problem. Lime and fertilizers are commonly used in fish farming to increase pH of pond soil and water and to increase alkalinity and hardness, reduce humic acid content and to initiate primary and secondary productivity. Devastating effect of lime on environment is likely to be minimal. In the case of fertilizers, over utilization of this agro-chemical could impair water quality as phytoplankton bloom become excessive which consequently raises BOD. The use of Therapeutants in aquaculture was discovered to be more popular in Europe and North America than in the tropics (Africa). Commonly used therapeutants include antibiotics and antimicrobials. For fish pathology chemicals like formalin, potassium permanganate, Dipterex and malachite green are widely in use. Effluent from farms where these chemicals are commonly in use can distort the aquatic ecosystem. The changes in water quality, aquatic community structure and productivity caused by intensive aquaculture are typical of the impacts of pollution from a wide variety of sources like sewage, agricultural run-off and effluent discharges from industry
