Water governance in rural Namibia has profoundly changed since the early 1990s. After independence and in accordance with global environmental policies, it became a central theme of Namibia's environmental legislation to transfer the responsibility for managing natural resources to local user associations. In this article, I explore the emergence of new social forms at the intersection of existing cultural models and new rationalities for governance. Doing so combines an analysis of state legislation with the micro-politics of water governance in 60 pastoral communities. The ethnographic analysis reveals that different actors, including state bureaucrats as well as rich and poorer herd owners, have different understandings of how to share water. While the poorer often agree with the state policy that water is an economic good and should be paid for accordingly, only in about half of the communities do corresponding institutional regimes emerge. Using critical institutionalism as a theoretical guide, I offer a contribution to understanding how more than 20 years after Rio local institutions of resource governance emerge at the intersection of different, and often heterogeneous and intertwined, social fields.

The progress of Ethiopia's agriculture is constrained by climate change leaving smallholder farmers vulnerable. As a panacea to the challenge, development institutions, governments, and research organizations are progressively promoting climate-smart agriculture (CSA) to maximize productivity, increase the resilience of livelihoods and farming systems (adaptation), and minimize or stop greenhouse gas emissions to the atmosphere (mitigation). This review synthesized knowledge on the prospects of CSA and climate change in addressing the adverse effects of climate change and variability by revising 99 peer-reviewed journal articles.

Background: Though the Dietary Guidelines for Americans recommend that individuals drink water instead of sugar-sweetened beverages (SSBs), this behavior is influenced and reinforced by a complex network of structures and systems.
Objective: The objectives of this study were to develop a shared understanding among multiple stakeholders about the structural and underlying, interconnected drivers of SSB and water consumption in the Washington D.C.

Nickel (Ni) is required in trace amounts (less than 500 µg kg) in plants to regulate metabolic processes, the immune system, and to act as an enzymatic catalytic cofactor. Conversely, when nickel is present in high concentration, it is considered as a toxic substance. Excessive human nickel exposure occurs through ingestion, inhalation, and skin contact, ultimately leading to respiratory, cardiovascular, and chronic kidney diseases.

The natural, built, and social environments shape drinking water quality supplied by private wells. However, the combined effects of these factors are not well understood. Using North Carolina as a case study, we (i) estimate the demographic characteristics of the private well population; (ii) evaluate representation in well testing records; and (iii) demonstrate how spatial scale influences knowledge of well-using household demographics and representation in testing.
