Khaw, HL. (2014). Cooperative and uniform fish? Social interactions and variability in live body weight in the GIFT strain (Nile tilapia, Oreochromic niloticus) in Malaysia. PhD thesis, Wageningen University, the Netherlands.
Social interactions are present everywhere in the living world. Such social interactions may lead to indirect genetic effects (IGE), which are heritable effects of an individual on trait values of the other individuals its interacts with. IGEs may affect the direction and magnitude of response to selection in breeding programs. Moreover, social interactions may affect variability of traits. In aquaculture, competition for resources inflates size variation within populations. In this thesis, we used the Genetically Improved Farmed Tilapia (GIFT; Oreochromis niloticus) strain to investigate the genetic basis for social interactions and variability in harvest weight for tropical finfish. Social interaction experiments were established for quantifying the genetic and non-genetic indirect effects on harvest weight in the GIFT strain. We found evidence for IGEs on harvest weight, and a negative direct-indirect genetic correlation, which suggesting heritable competitive interactions for harvest weight in GIFT. Hence, breeding schemes may need to be adapted to avoid an increase in competition. A stochastic simulation study was conducted to examine the effect of BLUP selection on the rate of inbreeding for socially affected traits. The rates of inbreeding for scenarios with IGEs were greater than for scenarios without IGE. Therefore, with IGEs there is a greater need for a selection algorithm that restricts the increase of mean kinship. In aquaculture industry, there is a wide range of commercial production environments, which may leads to genotype by environment (GxE) interaction, for example due to differential social interactions. The GIFT fish were tested in ponds and cages to study the GxE interaction. The genetic correlations between environments (0.73 to 0.85, for harvest weight and body measurements) indicate little GxE-interaction. The data collected from the social interaction experiments were also used to investigate the presence of genetic variation in uniformity for harvest weight. The genetic coefficient of variation for standard deviation of harvest weight (0.17) shows that uniformity of harvest weight is heritable and can be increased by selective breeding. In the General Discussion of this thesis, the uniformity study was extended to incorporate IGE. The result indicates that more cooperative fish are not necessary more uniform for harvest weight. Overall, our results suggest that genetic improvement in fish breeding programs can be increased by accounting for social interactions.

Land degradation is a global concern. In tropical areas it primarily concerns the conversion of forest into non-forest lands and the associated losses of environmental services. Defining such degradation is not straightforward hampering effective reduction in degradation and use of already degraded lands for more productive purposes. To facilitate the processes of avoided degradation and land rehabilitation, we have developed a methodology in which we have used international environmental and social sustainability standards to determine the suitability of lands for sustainable agricultural expansion. The method was developed and tested in one of the frontiers of agricultural expansion, West Kalimantan province in Indonesia. The focus was on oil palm expansion, which is considered as a major driver for deforestation in tropical regions globally. The results suggest that substantial changes in current land-use planning are necessary for most new plantations to comply with international sustainability standards. Through visualizing options for sustainable expansion with our methodology, we demonstrate that the link between oil palm expansion and degradation can be broken. Application of the methodology with criteria and thresholds similar to ours could help the Indonesian government and the industry to achieve its pro-growth, pro-job, pro-poor and pro-environment development goals. For sustainable agricultural production, context specific guidance has to be developed in areas suitable for expansion. Our methodology can serve as a template for designing such commodity and country specific tools and deliver such guidance.

Salinity is a major environmental constraint on crop productivity and grafting can be a sustainable strategy to enhance plant tolerance under adverse growth conditions. Screening different graft combinations under field conditions can be a slow and expensive processes. In this study, plants of 18 genotypes of Capsicum spp. were evaluated during 5 months to select salt tolerant plants to be used as rootstocks in greenhouse under controlled conditions. Their net photosynthetic rate was used as a rapid and sensitive methodology for screening their tolerance to salt stress conditions. The germination potential of some genotypes was also tested under different salinity conditions to see if it would be useful to accelerate the screening process. According to photosynthesis rate, the commercial rootstock ‘Tresor’ and the genotypes ‘Serrano’ (C. annuum), ‘ECU-973’ (C. chinense) and ‘BOL-58’ (C. baccatum) were the most tolerant during this period. Nevertheless, the evaluation of pepper genotypes for salinity tolerance based on the germination performance and chlorophyll fluorescence parameter Fv/Fm ratio were not good indicators of the sensitivity along plant ontogeny. Finally, the selected genotypes as salt-tolerant were validated under field conditions as rootstocks of two interesting pepper cultivars, concluding that using the rootstocks selected by the net photosynthetic rate improved the salt tolerance of the scion in terms of marketable yield and fruit quality.

International medical travel (IMT), people crossing national borders in the pursuit of healthcare, has become a growing phenomenon. With many of the countries currently being promoted as IMT destinations located in the ‘developing’ world, IMT poses a significant challenge to popular assumptions about who provides and receives care since it inverses and diversifies presumed directionalities of care. This book analyses the development of international medical travel in Malaysia, by looking at the benefits and challenges of providing health care to non-Malaysians. It challenges embedded assumptions about the sources, directions and political value of care. The author situates the Malaysian case study material at the fruitful cross-section of a range of literatures on transnational mobility, hospitality, therapeutic landscapes and medical diplomacy to examine their roles in the construction of national identity. The book thus contributes to wider debates that have emerged around the changing character of global health governance, and is of use to students and scholars of Southeast Asian Studies as well as Politics and Health and Social Care.

One of the measures that can help developing countries in meeting Target 10 of the Millennium Development Goals – halving the number of people without access to water and adequate sanitation by 2015 – is through a water sector reform. In this research the Malaysian water sector reform is assessed by answering the following questions: • How can we understand and explain the policy process of the reform? • To what extent have the outputs of the reform contributed to the realization of the reform’s objectives? and • To what extent has the water sector reform improved the operational efficiency and environmental effectiveness of water utilities? This research was approached from two theoretical perspectives: the policy arrangement approach and the policy evaluation approach. The policy arrangement approach provides the analytical tools to ascertain answers to the first question. This is done by thoroughly investigating the main discourses underpinning the water sector reform, the resources-power nexus, the actors and the rules applied and created in the reform process. The policy evaluation approach answers the remaining two questions from two aspects. First, by assessing the output efficacy of four institutional outputs against the reform objectives. Second, by assessing seven quantitative indicators related to the performance of water utilities on operational efficiency and environmental effectiveness. Chapter 1 takes us through the historical development of the Malaysian water supply sector from as early as the 19th century. The first water supply development has taken place in the Federated Malay States and the Strait Settlement under the British administration. Over the years, continuous investments have put Malaysia amongst countries with high access to drinking water in the world. As the country developed and economic development accelerated, public funding proved no longer able to satisfy budgets needed for water infrastructure development. Turning to private sector assistance has neither solved this problem, nor relieved state governments from financial burdens. Political and socio-economic reasons prohibit water from being priced at its actual costs. Low tariffs (and subsidised tariffs) do not only hamper water conservation, but also deprive water utilities from generating extra revenues to sustain operation and to expand services to new areas. Chapter 2 consists of two parts. The first part presents a general overview of water supply reform processes and explains the key concepts – equilibrium levels, efficiency, effectiveness, equity, competition and unbundling – which are highly relevant to the analysis of water supply reform in Malaysia and beyond. The second part discusses two theoretical frameworks used in this research: (1) the policy arrangement approach for understanding and analysing the reform process; and (2) the policy evaluation approach for measuring the outcomes of the reform on seven indicators: four for operational efficiency – non-revenue water, collection efficiency, unit production cost and customer complaints – and three for environmental efficiency – sludge management, water quality and information disclosure. The last section of this chapter formulates a theoretical framework for this research and explains how this framework helps to answer the research questions. Also Chapter 3 is divided into two parts. The first part reflects on the leading events of and driving forces behind the reform process. This includes re-visiting the policy decision of the National Water Resources Council made in 2003, the formation of the Ministry of Energy, Water and Communications right after the 2004 general elections, the commissioning of a major study and the amendment to the Federal Constitution. The reform accelerated the desire to address the presence of high non-revenue water, low water tariffs, weak regulation and the unviable financial mechanism for coping with the issue of under-investment and over-dependency on public funding in the water sector. The second part analyses the outcomes of the reform from four perspectives: regulation, water resource management, financial and operational issues. The analysis produced mixed results. Considerable positive achievements are clearly visible with regard to the role of the central regulator on regulation oversight, the financial mechanism of the PAAB and the corporatisation of state water departments. But the state water resources regulator has not shown promising results in safeguarding water resources. In Chapter 4, the water supply sector reform is analysed using the policy arrangement approach. The analysis shows a shift in water management towards the public control both at the federal and state government levels. This can be seen from the dominating corporatisation discourse, showing a growing tendency towards centralisation of water management. The shared-responsibility approach gives the federal government powers on water regulation and financing matters while reinforcing the dominant role of state governments on water provisioning and water resources. The dominant role of state actors in water is aided by their possession of vast resources – legal, water rights, financial – thus undermining the presence of market actors (private water utilities) in the sector. By the same token, several unprecedented rules emerged from the reform. The most noticeable one is the participation of the Prime Minister and his Deputy during the reform process. Others include the declassification of the public documents, drafts of WSIA and SPANA, from the official secret law to solicit public feedback, and the public hearings process involving members from the opposition parties as well as civil society. Chapter 5 presents the assessment of four operational efficiency indicators: non-revenue water, collection efficiency, unit production costs and customer complaints. The assessment was furthered investigated in two cases studies – PBAPP and SADA. It became evident that private water utilities are superior in managing water losses and collection efficiency compared to their counterparts in the public sector, while there is no clear distinction with regard to their capability in managing costs and customer complaints. This research re-affirms the contribution of nonreform factors to the performance of water utilities before and after the reform, and between private and public water utilities. The findings from the two cases studies confirm the general findings of this research. This chapter also highlights the importance of performance indicators (as a regulation tool) in the water sector in which successful reform depends considerably on the presence of reliable information. Chapter 6 analyses the performance of water utilities on three environmental effectiveness indicators: sludge management, water quality and information disclosure. Similar to Chapter 5, private water utilities demonstrate a higher compliance level to sludge management under the Environmental Quality Act 1974 and information disclosure requirements than their counterparts in the public sector. Both private and public utilities have a good compliance level in relation to the National Guideline for Drinking Water Quality Standard 2001 for water quality. Findings from the two case studies confirm the presence of a weak relation between the reform and the performance of water utilities on environmental effectiveness indicators. This chapter highlights the call from water utilities to the government to establish sludge treatment companies to spearhead the research and development activities in sludge recycling and to avoid direct discharge of raw sludge into streams. The majority of water utilities are aware of the mandatory information requirement under Section 29 WSIA. By the same token, civil society groups such as CAWP call for a greater information disclosure transparency by making all documents related to the function of NWSC and water utilities available to the public. Lastly, this chapter proposes for adoption of environmental indicators in measuring the performance of water utilities as well as to strengthen the link between information holders/disclosers and information users to facilitate greater transparency and democratic practices in the water sector. In conclusion, Chapter 7 answers the research questions as follows: (1) the policy process of the Malaysian water sector reform represents the current global trend in centralising water management within the public domain with a clear division of tasks between policy formulation, regulation oversight and service provision. State actors – the federal government on policy formulation, regulation and financing; state governments (through state water companies) on water provisioning and water resources – become dominant players in the water sector; it reduces the role of private water utilities to only a fraction of activities (i.e. treatment) within the entire value chain of water; and it strengthens close regulation oversight from the regulator. Lastly, there is a growing influence of civil society groups on the water sector; (2) the output effectiveness analysis (of the reform) has produced mixed results. Despite the fact that the central regulator, water corporations and the financier are proven to be the important institutions that meet the objectives, the state water resources regulator has not (yet) shown to be a significant institution in meeting the objective of safeguarding water resources; and (3) due to the timing of this research and limited data availability, it proved difficult to link the performance of water utilities on operational efficiency and environmental effectiveness to the reform. This study further concluded that the relevance of the policy arrangement approach and the policy evaluation approach frameworks for policy evaluation research are enhanced when they are used in combination. Moreover, the application of the latter to assess water sector performance in the data-poor environments experienced in this research presses for more use of expert judgments to complement incomplete and unreliable quantifiable datasets. It is suggested that further research be carried out over a longer time interval when required data are available, laws are fully enforced and the reform institutions are well functioning. Such research should involve a wider selection of case studies of the entire domain of water utilities using both theoretical frameworks. The immediate policy recommendations include the call to the government to consider measures to facilitate greater public participation in the policy making process of the reform, the consolidation of water management under a single water body and the establishment of a national and disclosed data bank for the water sector.

Nederland is een grote importeur van soja, palmolie en tropische houtproducten. Voor de import van soja uit Brazilië, palmolie uit Indonesië en Maleisië en hout uit Indonesië is in deze landen ruwweg dezelfde landoppervlakte nodige als de totale oppervlakte aan landbouwgrond in Nederland. Op die manier draagt Nederland bij aan het verlies van biodiversiteit in deze landen. Door duurzame intensivering van de productie, uitbreiding van de productie in gedegradeerde gebieden en geïntegreerde landinrichting in de exportlanden et stimuleren, kan de Nederlandse overheid de ecologische en socio-economische impact van de Nederlandse import reduceren

Forested tropical peatlands in Southeast Asia store at least 42 000 Million metric tonnes (Mt) of soil carbon. Human activity and climate change threatens the stability of this large pool, which has been decreasing rapidly over the last few decades owing to deforestation, drainage and fire. In this paper we estimate the carbon dioxide (CO2) emissions resulting from drainage of lowland tropical peatland for agricultural and forestry development which dominates the perturbation of the carbon balance in the region. Present and future emissions from drained peatlands are quantified using data on peatland extent and peat thickness, present and projected land use, water management practices and decomposition rates. Of the 27.1 Million hectares (Mha) of peatland in Southeast Asia, 12.9 Mha had been deforested and mostly drained by 2006. This latter area is increasing rapidly because of increasing land development pressures. Carbon dioxide (CO2) emission caused by decomposition of drained peatlands was between 355 Mt y-1 and 855 Mt y-1 in 2006 of which 82% came from Indonesia, largely Sumatra and Kalimantan. At a global scale, CO2 emission from peatland drainage in Southeast Asia is contributing the equivalent of 1.3% to 3.1% of current global CO2 emissions from the combustion of fossil fuel. If current peatland development and management practices continue, these emissions are predicted to continue for decades. This warrants inclusion of tropical peatland CO2 emissions in global greenhouse gas emission calculations and climate mitigation policies. Uncertainties in emission calculations are discussed and research needs for improved estimates are identified.

peat swamp forest - tropical peat - kalimantan - malaysia - fluxes - fires
Extensive degradation of Indonesian peatlands by deforestation, drainage and recurrent fires causes release of huge amounts of peat soil carbon to the atmosphere. Construction of drainage canals is associated with conversion to other land uses, especially plantations of oil palm and pulpwood trees, and with widespread illegal logging to facilitate timber transport. A lowering of the groundwater level leads to an increase in oxidation and subsidence of peat. Therefore, the groundwater level is the main control on carbon dioxide emissions from peatlands. Restoring the peatland hydrology is the only way to prevent peat oxidation and mitigate CO2 emissions. In this study we present a strategy for improved planning of rewetting measures by dam constructions. The study area is a vast peatland with limited accessibility in Central Kalimantan, Indonesia. Field inventory and remote sensing data are used to generate a detailed 3D model of the peat dome and a hydrological model predicts the rise in groundwater levels once dams have been constructed. Successful rewetting of a 590 km² large area of drained peat swamp forest could result in mitigated emissions of 1.4–1.6 Mt CO2 yearly. This equates to 6% of the carbon dioxide emissions by civil aviation in the European Union in 2006 and can be achieved with relatively small efforts and at low costs. The proposed methodology allows a detailed planning of hydrological restoration of peatlands with interesting impacts on carbon trading for the voluntary carbon market.

Horticulture production in Malaysia is located mainly in the highlands. Further expansion in this area is not possible. Growers are having to move to the lowlands, but the particularly high temperatures and humidity make this area less favourable for greenhouse cultivation. A recent study by Wageningen UR Greenhoude Horticulture in the Netherlands however, demonstrated that greenhouse production is certainly possible in this area, if good use is made of technical possibilities.

The Division Biobased Products of the WUR institute A&F was approached by the Dutch Ministry of Agriculture, Nature and Food Quality with a policy support question about the potential of Bio-based economic developments in Malaysia. Malaysia is one of the major international trade partners of the Netherlands. Annually 4.500 – 5.000 million euro’s worth of goods are imported from Malaysia. The Netherlands are Malaysia’s most important trading partner within the EU. The volume of agricultural commodities and especially palm oil products are substantial and the use of biobased resources for the generation of energy or biofuel has created a fierce debate on the sustainability of expansion of use of the biomass resources. In the context of the international policy to support the transition towards a biobased economy the potential resources that can be used for production of materials, chemicals and energy needs to be indentified. This report is reviewing the options that the current Malaysian agro-forestry sector may provide for sustainable developments. The main conclusions are that especially the currently underutilized residues and polluting wastes from the palm oil production have big potential for value addition and technical product development that also could substantially contribute to the reduction of greenhouse gas emissions. Examples can be found in fermentation of residues and effluents to produce bio-gas / ethanol or bioplastics but also fibre boards and building materials. Demonstration on pilot scale of such technologies could create new business and bilateral interactions between Malaysia and The Netherlands.
