Pós-graduação em Agronomia (Agricultura) - FCA; In the no - tillage system, soil acidity correction practice is restricted to limestone use and there is little information regarding the use of steel slag. The study aimed to evaluate the amendments in soil chemical attributes, yield and nutrient u ptake of common bean, soybean and black oat according to the application forms of slags, compared to limestone, in the implantation of no till system. The experiment was conducted under a Rhodic Hapludox for three years (2010 - 2013). The treatments consiste d of surface and incorporated application of seven soil acidity correctives: steel slag (SS), blast furnace slag (BFS), ladle furnace slag (LFS), stainless steel slag (“agrosilício”) (AG), wollastonite (W), lime (L) and calcined dolomite lime (CDL), plus o ne control without corrective application. Each material dose was calculated to raise the base saturation to 70%. In February 2011, the first cultivation of bean ( Phaseolus vulgaris ) occurred. Afterwards, the experiment was developed according to a success ion of cultures, that is, in winter black oats was sown ( Avena strigosa ) and in summer, soybean ( Glycine max ) was sown. Soil acidity correctives materials provided changes in soil chemical properties...

Special Program for African Agricultural Research (SPAAR) was established in 1985 to foster collaboration in agricultural research and development in Sub-Saharan Africa (SSA) between donor organizations and African agricultural research systems. It also sought to enable Africa to benefit from the accumulated knowledge of global agricultural research and technology generation and transfer. The SPAAR membership consists of twenty-three donor organizations, comprising of bilateral and multilateral donors, international, autonomous and regional agencies. Its Secretariat is housed in the World Bank. In 1994, SPAAR donors decided to open SPAAR membership to all the national agricultural research systems (NARSs) in SSA.

This report focuses on areas with highest potential efficiency gains to increase the value for money from investments in core public goods and services such as extension, irrigation and rural roads. This is a first attempt to carry out such an analysis in Cambodia, and even in the Greater Mekong sub-region. Based on extensive data gathering and surveys, this chapter analyzes the efficiency and effectiveness of agricultural sector expenditures in Cambodia and assesses various options for increasing the impact of government expenditures on agricultural growth. Other challenges include an excessive focus on rehabilitating primary irrigation infrastructure and a neglect of secondary and tertiary systems, a lack of maintenance of irrigation and rural roads, and the slow pace of developing or adopting new technologies to reduce future maintenance costs. There is also a need to better prioritize agricultural and related infrastructure expenditures, both by type and by geographic location, to maximize their impact on growth. The rest of the report is organized as follows. Chapter two presents recent developments in the agriculture sector of Cambodia. Chapter three gives an overview of sectoral expenditure trends over the last decade. The budget process and its relationship to sectoral development strategies is discussed in chapter three. Chapter four discusses the novel contribution of the AgPER in analyzing the efficiency and effectiveness of government spending using benefit-cost analysis to examine select public investments. Chapter five discusses how likely climate change trends may affect future agriculture expenditures and suggests some priority areas for public spending. The conclusion section summarizes the major findings and policy recommendations of the report.

Government grain marketing policy has an important impact on farmers’ production behaviour, which, in turn, directly tests government grain marketing policy. In 1998, the Chinese government issued a new grain marketing policy package. What have been farmers’ reactions to the new package? This paper uses farmer household grain production and marketing survey data for 1,000 farmer households from the five provinces of Shandong, Henan, Jiangxi, Jilin and Sichuan for the period 1999-2000 to analyse farmers’ reactions to the new grain marketing policy. The study focuses on farmers’ grain marketing channels and changes in grain production in terms of grain-sown areas and grain production inputs. The farmer household survey was conducted jointly by the Department of Policy and Law, Chinese Ministry of Agriculture (MOA), and the Chinese Economies Research Centre (CERC), Adelaide University, Australia, and was sponsored by the Australian Council for International Agricultural Research (ACIAR).; no

[Conclusion]: This exploration into the application of the SPS regime in the processed food products in India was focussed on five processed product lines, each from a different segment of the wide spectrum of available products. It was observed that all selected processed food products were assisted by the policy liberalisation regime of the early 1990s. But, in the post-WTO period, particularly since 1996/97, the complexity of the SPS regime seems to have significantly constrained market access in developed countries for Indian processed food products. The poultry product (e.g., egg powder) and marine (Shrimps) product exports to EU and USA reveal contrasting scenarios. Egg powder plants in India that were dedicated to produce exports to the EU markets closed down because of the imposition of stricter food safety standards. On the other hand, the EU approved plants for processing marine products, many exporters could not understand or cope with the shifting safety standards, and they explored alternative markets. As a result, the realized unit value of these exports declined. The hiatus between scientific merit and trade economics is further brought home, when the application of SPS measures to Peanuts/Groundnuts, Mango Pulp and Mushrooms export lines are examined. The case studies confirm the untenability of higher and stricter food safety standards in EU and USA...

THIS PUBLICATION CONTAINS a report of a research project: Improving smallholder farming systems in Imperata areas of Southeast Asia: a bioeconomic modelling approach. The project was formally a collaborative effort between the Centre for Resource and Environmental Studies, the Australian National University (CRES, ANU), Canberra, the SEAMEO Regional Center for Graduate Study and Research in Agriculture (SEARCA), Laguna Philippines, and the Centre for Agro-Socioeconomic Research (CASER), Bogor, Indonesia. However, many additional collaborations were undertaken, as evident from the list of contributors. The project received substantial funding assistance from the Australian Centre for International Agricultural Research (ACIAR) and the Center for International Forestry Research (CIFOR). The introduction to the report outlines the nature of the Imperata problem and the methodology used. Imperata is essentially restricted to upland areas, since it does not coexist with lowland rice farming. Section 1 contains a bioeconomic analysis of traditional smallholder ‘shifting cultivation’ farming systems where the fallow is Imperata. Section 2 contains a series of case study descriptions of successful tree growing by smallholders on Imperata grasslands. The core modelling work of the project is reported in Sections 3 and 4. Various tree-based interventions are modelled with and without an animal component. Some of these modelled farming systems are already in place in farmers’ fields. In these cases...

The Spatial optimisation Model for Analysing Catchment Management (SMAC) has been developed to examine the relationship between groundwater accessions from agricultural land, land salinisation and its medium-term economic effects. This mathematical programming model represents the farm and catchment-scale aspects of land management. The model quantifies the relevant inter-relationships between socio-economic conditions, including the economic and policy environment affecting farms, and the biophysical condition of the catchment, including agronomy, hydrogeology and soil salinisation. The SMAC model was chosen as the catchment-modelling tool in an ACIAR project on salinisation to be carried out by a research team headed by the University of Technology, Sydney and, in Thailand, the project will involve Khon Kaen University, The Royal Forest Department and the Land Development Department of the Ministry of Agriculture and Cooperatives. SMAC will be applied for hydrological, economic and social modelling, at catchment and other scales to evaluate the impact of revegetation in Thailand (Lam Pao and Khorat and Australia (Liverpool Plains and Upper Macquarie Valley). This paper describes the SMAC model and discusses the methodological and other challenges of applying it in other regions with different land-use systems...

[Conclusion]: Barriers to international trade in agricultural and food products exist for several reasons, one of which is to ensure food safety. Food safety is a credence characteristic and this attribute causes market failure through imperfect and asymmetric information. One way in which government intervention in importing countries can improve upon the market outcome is to impose trade regulations as a way of providing the missing information. Any such regulations need to be consistent with the SPS Agreement. It is also in the interests of governments in exporting countries to overcome the market failure by putting in place regulations to ensure that their exports of food meet minimum levels of food safety. The issue for them is whether their regulations should be enforced through public or private agencies. Because of the credence characteristic of food safety, it is not possible for private firms credibly to commit to the provision of high-quality food exports in the absence of regulation. In the application of the SPS Agreement to the area of consumer health and food safety, there is no scope for consumers preferences to be taken into account. The consistency of import regulations is based on risk assessment involving only estimates of probabilities. There is no place for consumers preferences about risk or for economic considerations. This omission is perhaps the outcome of the original negotiations based upon pragmatism and the need to get agreement but it is an inherently unsatisfactory aspect of the Agreement. A better approach would be to incorporate consumers preferences and non-additive probabilities into a more comprehensive decision-making framework. The link between food-safety standards...

The purpose of this paper is to place the research project in the context of the ongoing global policy debate with a view to obtaining feedback from the interested parties in shaping the research strategy and facilitating their participation in the process of project implementation. The paper is structured as follows. Section 2 surveys the emerging trends and patterns of processed food exports and their implications for development policy in agricultural-resource rich developing countries. Section 3 paints a broad-brush picture of the current state of the debate on trade-impeding effects of international food-safety standards and the relation world trade rules. Section 4 presents preliminary results from a study-in-progress on inter-country differences in the incidents of import detentions by the US Food and Drug Administration (USFDA) and the underlying cause of detention. These results aim to inform the discussion on designing appropriate methods and strategies for studying the problems faced by exporting firms in India and Thailand in meeting food-safety standards and designing institutional capabilities to facilitate redressing these problems. A brief survey of the existing literature on the subject is undertaken in Section 5...

The purpose of this report is to examine the viability of funding an increase in Northern Australia's tropical health and medical research capacity through a foreign aid budget allocation. The report reviewed the scope for increasing medical research funding and improving aid effectiveness. It also entailed a case study of the Australian Centre of International Agricultural Research (ACIAR) that could form a model for supporting an increased medical research capability. Further, the report analysed the existing foreign aid budget allocation and the proposed future increases. Australian Centre of International Agricultural Research (ACIAR) pose a significant public health challenge to Northern Australia. These challenges are primarily attributable to Northern Australia's geographical location, climate, rapid population growth, and tropical health threats from the neighbouring countries with underdeveloped health capacity. To mitigate these health threats, Australian governments should consider providing more funding support to increase the tropical health and medical research capacity in Northern Australia. Australia's foreign aid budget could be an important funding source. In the context of a relatively large and rapidly increasing aid budget...
