A revision of the genus Actephila (Phyllanthaceae) in the Malesian region 16
Heijkoop, M.; Welzen, P.C. van.
The genus Actephila (Phyllanthaceae) is distributed from India in the north-west to Thailand and via Malesia to the Melanesian Islands and Australia in the south-east. Eleven species are recognized of which three are newly described, A. discoidea with long leaf apices and a fleshy nectar discs, A. emarginata with an emarginate leaf base, and A. stipularis with large stipules. Further, A. javanica is synonymized with A. excelsa; and a former synonym or separate variety, A. excelsa var. acuminata, is recognized as distinct species, but had to be synonymized under A. subsessilis. Actephila puberula, not present in Malesia, but often synonymized with A. excelsa, is kept separate because of the hairy ovary and different base of the leaf blades.

A revision of the Genus Scincella (Reptilia: Sauria: Scincidae) of asia, with some notes on its evolution 16
Ouboter, P.E..
Of the genus Scincella Mittleman, 1950 (sensu Greer, 1974) 337 specimens from Asia were examined for 74 characters, which were treated in a numerical-taxonomic way. The dendrogram resulting from this analysis was not stringently adhered to. Because of the wide variation in certain numerical scale characters within one taxon or even within one population, these characters (used by many authors as key characters to separate taxa) are not regarded as very important. For sympatric and parapatric species other characters, including relative size of head, body and limbs, are regarded as very important, because these characters are influenced by the way of life (niche separation). For the separation of allopatric species scale-numbers, but many other characters...

A taxonomic revision of the Pleistocene Hystrix (Hystricidae, Rodentia) from Eurasia with notes on the evolution of the family 16
Weers, D.J. van.
Measurements of many hundreds of the high-crowned cheek teeth of Hystrix specimens from the Euro-Asiatic Pleistocene in the collections of European and Asiatic institutions have been compared with extant species for a revision of the genus. A review is given about the extant genera and species of the family. The number of recognisable Euro-Asiatic species in the fossil record is reduced from eight to five. The European H. (A.) vinogradovi Argyropulo, 1941 is here considered to be a synonym of H. (A.) brachyura Linnaeus, 1758, and the three Asiatic species H. (H.) crassidens Lydekker, 1886, H. (H.) gigantea Van Weers, 1985 and H. (H.) magna Pei, 1987 are synonymized with H. (H.) refossa Gervais, 1852. Most of the Chinese fossil specimens are properly...

Agricultural Development in Traditional Asian Economies: Observations Prompted by a Livestock Study in Vietnam 31
Tisdell, Clement A..
China began its economic reforms in 1979 and Vietnam followed in 1986. Since then both countries have experienced rapid economic growth, falling poverty rates and significant rises in per capita income. At the same time, substantial restructuring of their economies has occurred, a feature of which has been a decline in the relative contribution of agriculture to total employment and output. These changes are outlined. Significant changes have also occurred in the agricultural sectors of China and Vietnam and these are reviewed. In both countries, the livestock sector has grown in relative importance. Households are the main contributors to agricultural production but their individual holdings of land are small and households keeping livestock mostly only...

Asian Rice Policies and WTO Commitments on Domestic Support Under Existing and Proposed Doha Round Provisions 31
Yang, Min-Hsien; Blandford, David.
We examine current rice policies in four major Asian countries (China, Japan, Korea, and Taiwan), their relationship to current WTO disciplines, and to those proposed under the Doha negotiations. WTO disciplines have prompted some changes in rice policies, but disciplines of domestic support are unlikely to impose serious constraints in the future. Using the example of Taiwan, we examine how existing support policies could be changed to reduce domestic distortions and satisfy WTO commitments. Changing from existing amber box payments to those that would likely qualify for inclusion under the blue or green boxes could allow greater market orientation in Taiwan’s rice market, while satisfying food security and farm income support objectives.

Asymmetric Response of Nutrient Intakes to Cereal Price Changes among the Poor in China: Implications for the Effect of Cereal Price Subsidies on the Poor’s Nutrient Intakes 31
Shimokawa, Satoru.
Previous studies commonly assume that the effects of introducing and ending cereal price subsidies on the poor’s nutrient intakes are symmetric. We question the assumption of symmetry and show that the poor’s nutrient intakes respond asymmetrically to declines and increases in the price of cereal in China. Our results imply that introducing cereal price subsidies can increase the poor’s total energy intake by increasing their calorie intakes from fat and protein, and that ending such subsidies would insignificantly affect the poor’s total energy intake; however, it may further increase their calorie intakes from fat and protein.

Atlas of Organics: Four maps of the world of organic agriculture 21
Paull, John; Hennig, Benjamin.
This paper presents four maps of the world of organic agriculture. Density equalising maps (cartograms) have previously been published of the world of organic agriculture based on the reported hectares of certified organically managed agriculture land. The four maps in the present atlas of organic agriculture are visual presentations of current global organics data: (a) certified organic agriculture hectares; (b) certified organic wildculture hectares; (c) total certified organic production hectares (organic agriculture plus wildculture plus forestry plus aquaculture); (d) certified organic producers. Australia dominates in the world map of the organic agriculture hectares, Europe is strongly represented, and Africa is weakly represented. Finland dominates...

Bhutan's plans to go 100% organic make progress 21
Paull, John.
Bhutan's Minister for Agriculture and Forestry, Dr Pema Gyamtsho, confirmed aspirations for his country to be the world's first country to go 100% organic. Certifying a whole country as organic would set a new challenge for certifiers. At the 2013 Delhi Sustainable Development Summit held this month in India, Gyamtsho stated: "Ours is a mountainous terrain. When we use chemicals they don't stay where we use them, they impact the water and plants. We say that we need to consider all the environment. Most of our farm practices are traditional farming, so we are largely organic anyway". The Bhutan Minister added that "we are Buddhists, too, and we believe in living in harmony with nature. Animals have the right to live, we like to to see plants happy and...

Changes in Organic Participatory Guarantee Systems (PGS) in Northern Vietnam 21
Tu Tuyet, Nhung; Whitney, Cory W..
Organic Participatory Guarantee Systems (PGS) may be on important contribution to Organic 3.0. The way that PGS systems are managed can be a major determinant of their success. In Northern Vietnam differing management of PGS systems can determine their level of social and ecological success, as well as the impressions of farmers and retailers. Nevertheless, more farmers’ groups are turning to individual management and this may have negative consequences for the future of PGS in the region.

China-Australia: Organic opportunities 21
Paull, John.
A century ago, China’s sustainable agricultural practices were documented and praised by US Professor of Agriculture, Franklin King, for the successful stewardship of agricultural land over four millennia. Over the past decade, Australia and China have converted more land to organic agriculture than any other of the 160 countries reporting organic agriculture statistics (for Australia, 4.3 m newly converted hectares, and for China, 1.8 m hectares). Australia accounts for about a third of the world’s certified organic agriculture hectares. China’s ‘economic miracle’ has been at the great cost of environmental degradation. There is a role for the development of organic agriculture in China to help achieve a clean green future. Added to this, consumers want...

Comparative Levels of Food Safety Regulations in Three U.S.-Asian Trading Groups 31
Wang, Yuan; Caswell, Julie A..
U.S.-Asian trade currently represents about 35% of the total value of U.S. agricultural and food trade. Country-by-country comparisons show significant differences in level of food safety regulations in the U.S., Japan, newly industrialized countries in Asia, and Asian developing countries. These disparities result in significantly different import requirements that may impede trade in agricultural and food products.

Comparison of Neogene low-crowned Hystrix species (Mammalia, Porcupines, Rodentia) from Europe, West and Southeast Asia 16
Weers, D.J. van.
The low-crowned Hystrix species known of the Neogene from Europe and Asia and some new finds from Shihuiba near Lufeng, South China, are compared on the basis of numerical data. The taxonomical allocation of the seven species recognised thus far is maintained. The occurrences of two coeval Eurasian late Turolian species is discussed. The material from Lufeng is described and allocated to Hystrix primigenia (Wagner, 1848), implicating an area of distribution of this species from S.E. Europe to S.E. Asia in the Turolian. In the northern Chinese Hystricidae the increase of the cheek tooth height is more advanced than in the the West Asiatic and European representatives. The difference in ecological environment of Hystrix gansuensis Wang & Qiu, 2002 (North...

This is the first of a series of papers that review the state of knowledge and practice regarding compensation and rewards for environmental services in the developing world. The paper begins with an assessment of the historical development of compensation and reward mechanisms within a broader context of changing approaches to nature conservation and environmental policy. The assessment shows that greater interest in compensation and reward mechanisms has emerged within a policy context of changing approaches to nature conservation and flexible multi-stakeholder approaches to environmental management. In the developing world, an even greater variety of perspectives has emerged on the opportunities and threats for using compensation and rewards for...

Cryptic variation and recent bipolar range expansion within the Stumped-Toed Gecko Gehyra mutilata across Indian and Pacific Ocean islands 16
Rocha, S.; Ineich, I.; Harris, D. James.
With an impressively wide distribution, Gehyra mutilata is present on almost all Indian and Pacific Ocean islands and in large regions of Southeast Asia and Indonesia. Mitochondrial sequence data (~500 bp) from individuals covering large parts of its (mainly insular) distribution reveals deep cryptic variation and strong geographic structure, with two well differentiated lineages. Molecular data also reveals that the wide Indian and Pacific insular distribution of Gehyra is very recent and, at least across the Indian Ocean islands, most probably the result of human-aided dispersal, as no variation within this lineage was found. Further research is needed to determine geographic patterns of variation across Southeast Asia, the level of genetic variation,...

Dairy Markets in Asia: An Overview of Recent Findings and Implications 31
Beghin, John C..
This paper is an overview of important findings regarding the ongoing evolution of Asian dairy markets based on a series of new economic investigations. These investigations provide systematic empirical foundations for assessing Asian dairy markets with their new consumption patterns, changing industries, and trade prospects under different domestic and trade policy regimes. The findings are drawn from four case studies (China, India, Japan, and Korea), as well as a prospective analysis of future regional patterns of consumption and a policy analysis of trade liberalization of Asian dairy markets. The overview distills the findings of these new investigations and integrates them in the earlier economic literature; it draws policy implications and...

Demand for fish in Asia: a cross-country analysis 31
Dey, Madan Mohan; Garcia, Yolanda T.; Kumar, Praduman; Piumsombun, Somying; Haque, Muhammad Sirajul; Li, Luping; Radam, Alias; Senaratne, Athula; Khiem, Nguyen Tri; Koeshendrajana, Sonny.
Fish demand patterns in nine Asian countries were investigated using a multistage budgeting framework allowing a disaggregated approach to analysing fish consumption. This paper highlights the heterogeneity of fisheries products in terms of species, sources and cultural responses of consumers, factors that are important in fish demand under the Asian setting. Specifically, fish demand by income groups were compared to determine how the low- and high-income households respond to price and income changes. Results showed that the estimated price and income elasticities of all fish types included in the study were relatively more elastic among the poorer households.
