American Radical Economists in Mao’s China: From Hopes to Disillusionment

American radical economists in the 1960s perceived China under Maoism as an important experiment in creating a new society, aspects of which they hoped could serve as a model for the developing world. But the knowledge of ‘actually existing Maoism’ was very limited due to the mutual isolation between China and the US. This paper analyses the First Friendship Delegation of American Radical Political Economists (FFDARPE) to the People’s Republic of China in 1972, consisting mainly of Union for Radical Political Economics (URPE) members, which was the first visit of a group of American economists to China since 1949. Based on interviews with trip participants as well as archival and published material, this paper studies what we can learn about the engagement with Maoism by American radical economists from their dialogues with Chinese hosts, from their on-the-ground observations, and their reflection upon return. We show how the visitors’ own ideas conflicted and intersected with their perception of the Maoist practice on gender relations; workers’ management and life in the communes. We also shed light on the diverging conceptions of the role for economic expertise between URPE and late Maoism. As the first in-depth study on the FFDARPE we provide rich empirical insights into an ice-breaking event in the larger process of normalization in the Sino-U.S relations, that ultimately led to the disillusionment of the Left with China

Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests

For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged management over more traditional coarse-grained even-aged management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous beech forest landscape of Germany and classified them into functional groups. Selected forest stands have been managed for more than a century at different spatial grains. The even-aged (coarse-grained management) and uneven-aged (fine-grained) forests are comparable in spatial arrangement, climate and soil conditions. These were compared to forests of a nearby national park that have been unmanaged for at least 20 years. We used diversity accumulation curves to compare γ-diversity for Hill-numbers 0D (species richness), 1D (Shannon diversity) and 2D (Simpson diversity) between the management systems. Beta diversity was quantified as multiple-site dissimilarity. Gamma diversity was higher in even-aged than in uneven-aged forests for at least one of the three Hill-numbers for six taxa (up to 77%), while eight showed no difference. Only bacteria showed the opposite pattern. Higher γ-diversity in even-aged forests was also found for forest specialists and saproxylic beetles. Between-stand β-diversity was higher in even-aged than in uneven-aged forests for one third (all species) and half (forest specialists) of all taxa, driven by environmental heterogeneity between age-classes, while α-diversity showed no directional response across taxa or for forest specialists. Synthesis and applications. Comparing even-aged and uneven-aged forest management in Central European beech forests, our results show that a mosaic of different age-classes is more important for regional biodiversity than high within-stand heterogeneity. We suggest reconsidering the current trend of replacing even-aged management in temperate forests. Instead, the variability of stages and stand structures should be increased to promote landscape scale biodiversity

Waldbewirtschaftung und Biodiversität: Vielfalt ist gefragt

Mit Ausnahme der Diskussionen zu den Auswirkungen zu hoher Schalenwilddichten wird in der Forstwirtschaft kaum ein Thema derzeit so leidenschaftlich diskutiert wie die Auswirkungen der Waldbewirtschaftung auf die Biodiversität [2, 3, 4]. Hierbei stehen Buchenwälder aufgrund ihres in Mitteleuropa gelegenen Verbreitungsschwerpunkts im Vordergrund der Diskussionen. Viele dieser Debatten münden letztlich in der Frage, ob und wenn ja wie viel der bislang bewirtschafteten Waldfl äche über die bisher vorhandenen Naturwaldfl ächen hinaus aus der Nutzung genommen werden sollte

The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests

For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged (UEA) management over more traditional coarse-grained even-aged (EA) management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous beech forest landscape of Germany and classified them into functional groups. Selected forest stands have been managed for more than a century at different spatial grains. The EA (coarse-grained management) and UEA (fine-grained) forests are comparable in spatial arrangement, climate and soil conditions. These were compared to forests of a nearby national park that have been unmanaged for at least 20 years. We used diversity accumulation curves to compare γ-diversity for Hill numbers 0D (species richness), 1D (Shannon diversity) and 2D (Simpson diversity) between the management systems. Beta diversity was quantified as multiple-site dissimilarity. Gamma diversity was higher in EA than in UEA forests for at least one of the three Hill numbers for six taxa (up to 77%), while eight showed no difference. Only bacteria showed the opposite pattern. Higher γ-diversity in EA forests was also found for forest specialists and saproxylic beetles. Between-stand β-diversity was higher in EA than in UEA forests for one-third (all species) and half (forest specialists) of all taxa, driven by environmental heterogeneity between age-classes, while α-diversity showed no directional response across taxa or for forest specialists. Synthesis and applications. Comparing EA and uneven-aged forest management in Central European beech forests, our results show that a mosaic of different age-classes is more important for regional biodiversity than high within-stand heterogeneity.
