Can South–South Cooperation Compete? The Development Bank of Latin America and the Islamic Development Bank

Southern‐led multilateral development banks (MDBs) play a key role in harnessing global capital to finance the sectors most important to borrowers, especially infrastructure. Two prominent Southern MDBs, the Development Bank of Latin America (CAF) and the Islamic Development Bank (IsDB), have become crucial drivers of regional infrastructure growth. This article explores whether their performance has lived up to their goals of establishing borrower control over bank governance without sacrificing financial dynamism. Using power‐weighted voting indices for member representation on bank boards, the authors determine that these banks offer borrowers much more representation on their boards than do their Northern‐based counterparts, the Inter‐American Development Bank (IDB) and the World Bank International Bank for Reconstruction and Development (IBRD). The article also analyses bank operations to determine whether their governance structure impacts their internal performance, as reflected on balance sheets, and external performance — gaining relevance in development finance and particularly in infrastructure lending, including the burgeoning sector of sustainable (climate‐resilient) infrastructure. The authors find that the CAF and IsDB have become major players in development finance, including in sustainable infrastructure. However, important issues remain in relation to their continued internal capacity development, especially with regard to the environmental and social safeguards necessary to oversee lending.     

Polycentric Systems of Governance: A Theoretical Model for the Commons

Polycentricity is a fundamental concept in commons scholarship that connotes a complex form of governance with multiple centers of semiautonomous decision making. If the decision‐making centers take each other into account in competitive and cooperative relationships and have recourse to conflict resolution mechanisms, they may be regarded as a polycentric governance system. In the context of natural resource governance, commons scholars have ascribed a number of advantages to polycentric governance systems, most notably enhanced adaptive capacity, provision of good institutional fit for natural resource systems, and mitigation of risk on account of redundant governance actors and institutions. Despite the popularity of the concept, systematic development of polycentricity, including its posited advantages, is lacking in the commons literature. To build greater clarity and specificity around the concept, we develop a theoretical model of a polycentric governance system with a focus on the features necessary or conducive for achieving the functioning predicted by commons scholars. The model is comprised of attributes, which constitute the definitional elements, and enabling conditions, which specify additional institutional features for achieving functionality in the commons. The model we propose takes the concept a step further toward specificity without sacrificing the generality necessary for contextual application and further development.     

Getting yourself out of the way: Aboriginal people listening and belonging in the city

Much is known about the meaning of Country to Aboriginal people living in northern Australia. Discourse abounds in various disciplines about how Country provides people in remote locations with a sense of belonging and place. Yet little is known about what Country means to Aboriginal people living in large urban locations such as Sydney, Australia. The two authors conducted a series of interviews with nine Aboriginal people about what Country and belonging mean for them in the city. A methodological relation between the two authors is explored as a means of reflecting on the role of mentoring in a research partnership, and on the transferal of research capacity through that collaboration. Older participants identify how listening and belonging are each governed by the other to the extent that there can be no belonging without listening. We draw on the frames of both human geography and philosophy to argue that listening depends on an ability to get yourself out of the way.     

An assessment of the value of bone density measurements to archaeoichthyological studies

This paper reviews the meaning of the term ‘density’ and the problems associated with the methods of density determination for animal bones in archaeology. It has often been assumed that density is the intrinsic property of most influence in controlling the rate of a bone's decay. Values for whole bone density have been published only for large mammal bone, however. Fish bone appears to be particularly vulnerable to decay, and usually a restricted range of skeletal elements are recovered from archaeological sites. The object of this study was to examine the relationship between fish bone density and the ability of the bone to survive on occupation sites and in archaeological deposits. A set of ‘density’ measurements was established for the bones of cod (Gadus morhua). The usefulness of these measurements as a predictive tool in archaeoichthyological studies is assessed. It was found that ‘density’ as measured did not explain adequately the relative survival of skeletal elements after mechanical abrasion and weathering, or within archaeological deposits.     

Manuring and stable nitrogen isotope ratios in cereals and pulses: towards a new archaeobotanical approach to the inference of land use and dietary practices

This paper explores the impact of animal manure application on the δ¹⁵N values of a broad range of crops (cereals and pulses), under a range of manuring levels/regimes and at a series of locations extending from northwest Europe to the eastern Mediterranean. We included both agricultural field experiments and areas where ‘traditional’ farming is practised. Our aim is to ground-truth interpretation of δ¹⁵N values in archaeobotanical crop remains as evidence of past growing conditions and husbandry practices. The results confirm the potentially radical impact of manuring on δ¹⁵N values in cereals, depending on manuring level, but indicate only a slight effect on pulses, which can fix atmospheric nitrogen. The expected geographical trend towards greater δ¹⁵N with increasing climatic aridity is not apparent, probably because the growing conditions for crops are ‘buffered’ through crop management. Each of these observations has fundamental implications for archaeobotanical interpretation of δ¹⁵N values as evidence of land use practices and (together with analysis of bone collagen/tooth enamel in potential consumers) palaeodiet.     

Considerations on the provenance determination of plant ash glasses using strontium isotopes

Strontium isotopic analysis has been proposed as a suitable method to determine the primary production location of ancient plant ash glasses. The technique is based upon the assumption that Sr enters this glass type with the plant ash used as a flux material, and that the ⁸⁷Sr/⁸⁶Sr ratio of the resulting glass reflects the geological provenance of that flux. In such case, the bulk Sr isotopic composition of the bedrock should be inherited unchanged in the plants growing on that bedrock. Different types of plant ash glasses have been shown to have widely differing ⁸⁷Sr/⁸⁶Sr compositions. In this study, the ⁸⁷Sr/⁸⁶Sr composition of several plant species growing on different bedrock types is measured, and compared to the bulk Sr isotopic composition and petrology of that bedrock. The paper shows that the ⁸⁷Sr/⁸⁶Sr ratio of these plants is a function not only, or even mostly, of the local geology, but also of the Sr isotopic composition of the total water consumed by that plant. This is highly likely to be both plant species dependent and dependent on the small-scale hydrology of the area immediately surrounding the plant. In this way, no definite relation between the isotopic composition of a geological outcrop and the plants growing on this bedrock can be inferred. Hence, the isotopic composition of a plant ash made from such plants is uncertain and moreover species dependent. Though groups of plant ash glasses can certainly be compared in time and space using Sr isotopes, it may prove difficult to ascertain a plant ash glass type to a specific geographical-geological region.
