Land subdivision of Maasai group ranches around Amboseli National Park, Kenya: Drivers, impacts, and the influence of conservation organisations
Even though it has allowed Maasai pastoralists to uphold forms of community rangeland management for their livestock, the group ranch regime introduced in Kenya in 1968 was never considered satisfactory. Despite offering democratic opportunities to sustain these traditional practices under new rules, the Community Land Act (CLA) of 2016 has triggered instead a scramble to subdivide rangeland into small, privately owned plots in the Amboseli regio…

Diffuse land control, shifting pastoralist institutions, and processes of accumulation in southern Kenya
In East Africa, pastoralist systems are undergoing rapid transformation due to land enclosures, benefit distributions associated with new land uses, shifting social relations, and changing authority and governance structures. We apply a critical analysis of the institutions that mediate access and benefits across a complex mosaic of property relations within Ilkisongo Maasai pastoralist land in southern Kenya. Our analysis elucidates how global a…

Accelerated degradation of Lake Inle (Myanmar): A baseline study for environmentalists and developers
This study takes stock of the confusion that exists around the environmental state of Lake Inle, a flagship destination for tourism in Myanmar. Reports on the dynamics of its iconic floating gardens and on the evolution of the Lake's dimensions in response to land‐use change in the watershed are inconsistent and provide a poor basis for policymaking. Here, we (a) present a critical overview of the literature concerning land degradation around Lak…

Securing Aquaculture-Related Resources through Social Interaction in the Pampanga River Delta, Philippines: An Ethnogeographic Perspective on the Strengths and Pitfalls of Social Capital
Social relationships play a pivotal role in agricultural systems because they influence the economic behavior of stakeholders, but sociological studies aimed at understanding these links have until now not focused much on aquaculture. Here we examine how social capital among communities of the Pampanga River delta in the Philippines plays out in the conduct of aquatic livestock breeding, harvesting, and trading, and how it either facilitates or r…

Societal response to monsoon variability in Medieval South India: Lessons from the past for adapting to climate change
Future climate change will challenge society’s ability to adequately manage water resources, particularly in the developing world. The response of past societies to climatic variability, particularly in terms of water management, can provide useful insights into the timing and scale of response to future events. We present a regional case study from South India to illustrate the influence of climate on shaping the rise and economic prosperity of …

Exposure age chronology of the last glaciation in the eastern Pyrenees
We present a chronology of ice recession in the eastern Pyrenees based on in situ -produced 10 Be data obtained from the Têt paleoglacier complex. The sampling strategy is based on the relative chronology provided by a detailed geomorphological map of glacial landforms. Results indicate that the last maximum ice advance occurred late (i.e., during Marine Isotope Stage 2) compared to the chronology currently established for the rest of the Pyrenee…

Response of the South Indian runoff-harvesting civilization to northeast monsoon rainfall variability during the last 2000 years: Instrumental records and indirect evidence
Compared with the southwest monsoon, the mechanisms and history of northeast monsoon (NEM) variability over South Asia are poorly known. The NEM nevertheless contributes >50% of rainfall to semi-arid southeast India, and has underpinned the success, over the last 2000 years, of a widespread indigenous water resource management system based on rainwater harvesting and storage in man-made lakes. Based on a power spectrum analysis of 60- to 100-yr i…
Spatial heterogeneity of land cover response to climatic change in the Nilgiri highlands (Southern India) since the last glacial maximum
Fourteen hillslope soil profiles were sampled under natural vegetation (ie, grassland or forest) and plantations in the Nilgiri highlands, Southern India. Delta 13 C ratios were measured at different depths and 14 C ages determined for six profiles. In these highland soils where the turnover rate of organic matter is extremely low, the δ 13 C ratios of entire soil profiles have recorded signatures of past land cover. By correlating the data with …
Past and Present Status of Runoff Harvesting Systems in Dryland Peninsular India: A Critical Review
Many modern agricultural systems are structured around one dominant form of water storage and distribution, usually large reservoirs. In contrast, in peninsular India, small reservoirs (tanks), predominantly supplied by surface runoff as opposed to river canals have for centuries been the trademark of an entire agrarian civilization, with no equivalent elsewhere in the semiarid tropics. This article focuses on the physical and socioeconomic condi…

Comparative Regional Geography in India and West Africa: Soils, Landforms and Economic Theory in Agricultural Development Strategies
A classic exercise in geography consists of explaining the levels of economic development achieved by different regions with respect to their physical characteristics. In this paper a parallel is drawn between the agricultural systems of southern India and Sudano-Sahelian Africa, where possibilist theory, often dismissive of physical geography, has led authors to consider that Tamil Nadu agriculture should serve as a model of development for Afri…
