Sustainable Development, EarlyView.ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Bipartite Ramsey numbers involving stars, stripes and trees
Electronic Journal of Graph Theory and Applications, 2013 The Ramsey number R(m, n) is the smallest integer p such that any blue-red colouring of the edges of the complete graph Kp forces the appearance of a blue Km or a red Kn.

European Journal of Combinatorics, 1982 In the first section of this paper it is shown that the bipartite Ramsey number br(m, n) satisfies br(m, n)⩽2m(n−1)+1. (Beineke and Schwenk [1] conjectured br(m, n) = 2m(n−1) + 1 but Irving [17] showed that equality does not always hold.) The second section gives a conjecture for the Ramsey numbers of the complete graphs, and lastly the numbers of ...

Energy Poverty and Climate Shocks: Are Changing Weather Patterns Leaving South Africa in the Dark?
Sustainable Development, EarlyView.ABSTRACT Energy and climate change are deeply interlinked, with the latter exerting significant influence on energy demand and supply. In regions such as South Africa, where socio‐economic vulnerability is high, understanding how climate change affects energy poverty is essential to achieving the Sustainable Development Goals, particularly SDG 7 ...
