Climate change that has hit the world requires to make adaptation efforts so that agricultural productivity can be maintained. Alysicarpus vaginalis is one of the local variety forage that can grow in a various of environmental conditions. In this regard, a survey research has been carried out to study various types of local forages throughout Bali. The aim of the research is to obtain forages that have superior properties and can be developed in various regions in Bali. The survey sampling location refers to a map prepared specifically for that by overlaying a map of soil types, land use maps, and climate maps. Based on the results of the survey, several species of local forages that have superior characteristics have been found. One of them is Alysicarpus vaginalis plant as a forage superior, Alysicarpus vaginalis forage production as much as 46,302 kg DM ha-1 with 0.21% botanical composition. Keywords: Alysicarpus vaginalis, superior legumes, tropical forage

Climate change is already affecting agriculture, with effects unevenly distributed across the world. These changes will undoubtedly lead to a reconsideration of the question of the necessary crop rotations on the territory of the individual continents and sub-regions. Many researchers have conducted field experiments with different crop rotations on several soil types and have received determined results, but still lack concrete unified numerical estimates of the influence of different crops in them. This article presents several new developments of the problem in crop rotation. Different approaches to assessing the influences of predecessors are illustrated. Therefore, it is necessary to apply advanced mathematical-statistical methods and models for obtaining more precise estimates. The application of asymmetry analysis and Procrustes analysis in the evaluation of different crop rotations are given in details. Some results about favorable and unfavorable rotation pairs are given.

Climate change is a financial factor that carries with it risks and opportunities for companies. To support boards of directors of companies belonging to all jurisdictions, the World Economic Forum issued in January 2019 eight Principlescontaining both theoretical and practical provisions on: climate accountability, competence, governance, management, disclosure and dialogue. The paper analyses each Principle to understand scope and managerial consequences for boards and to evaluate whether the legal distinctions, among the various jurisdictions, may undermine the application of the Principles or, by contrast, despite the differences the Principles may be a useful and effective guidance to drive boards' of directors' conduct around the world in handling climate change challenges. Five jurisdictions are taken into consideration for this comparative analysis: Europe (and UK), US, Australia, South Africa and Canada. The conclusion is that the WEF Principles, as soft law, is the best possible instrument to address boards of directors of worldwide companies, harmonise their conduct and effectively help facing such global emergency.

Climate variability and climate change are of great concern to economists and energy producers as well as environmentalists as both affect the precipitation and temperature in many regions of the world. Among those affected by climate variability is the Scandinavian Peninsula. Particularly, its winter precipitation and temperature are affected by the variations of the so-called North Atlantic Oscillation (NAO). The objective of this paper is to analyze the spatial distribution of the influence of NAO over Scandinavia. This analysis is a first step to establishing a predictive model, driven by a climatic indicator such as NAO, for the available water resources of different regions in Scandinavia. Such a tool would be valuable for predicting potential of hydropower production one or more seasons in advance.

In recent years, a number of powerful arguments have been given for thinking that there should be suprastate institutions, and that the current ones, such as the World Trade Organization (WTO), International Monetary Fund (IMF), World Bank, and United Nations Security Council, need to be radically reformed and new ones created. Two distinct kinds of argument have been advanced. One is instrumental and emphasizes the need for effective suprastate political institutions to realize some important substantive ideals (such as preventing dangerous climate change, eradicating poverty, promoting fair trade, and securing peace). The second is procedural and emphasizes the importance of political institutions that include all those subject to their power in as democratic a process as possible, and builds on this to call for democratically accountable international institutions. In this chapter, the author argues that the two approaches need not conflict, and that they can in fact lend support to each other.

This chapter discusses the emergence of environmental history, which developed in the context of the environmental concerns that began in the 1960s with worries about local industrial pollution, but which has since evolved into a full-scale global crisis of climate change. Environmental history is ‘the history of the relationship between human societies and the rest of nature’. It includes three chief areas of inquiry: the study of material environmental history, political and policy-related environmental history, and a form of environmental history which concerns what humans have thought, believed, written, and more rarely, painted, sculpted, sung, or danced that deals with the relationship between society and nature. Since 1980, environmental history has come to flourish in many corners of the world, and scholars everywhere have found models, approaches, and perspectives rather different from those developed for the US context.

‘Man still bears in his bodily frame the indelible stamp of his lowly origin.’ On topics ranging from intelligent design and climate change to the politics of gender and race, the evolutionary writings of Charles Darwin occupy a pivotal position in contemporary public debate. This volume brings together the key chapters of his most important and accessible books, including the Journal of Researches on the Beagle voyage (1845), the Origin of Species (1871), and the Descent of Man, along with the full text of his delightful autobiography. They are accompanied by generous selections of responses from Darwin’s nineteenth-century readers from across the world. More than anything, they give a keen sense of the controversial nature of Darwin’s ideas, and his position within Victorian debates about man’s place in nature. The wide-ranging introduction by James A. Secord, Director of the Darwin Correspondence Project, explores the global impact and origins of Darwin’s work and the reasons for its unparalleled significance today.

BC’s forests have already faced two simultaneous, globally significant, epidemics linked to climate change; the Dothistroma needle blight epidemic in NW BC and the massive mountain pine beetle epidemic throughout the BC Interior. Building on these experiences, we have compiled our best estimates of how we believe other forest health agents may behave as climate change continues to influence our forests. We have drawn on literature from around the world but have focused on the situation in BC. We have made management recommendations based on what we have seen so far and what we expect to come.Key words: climate change, forest health, forest insects, forest pathogens, forest management, British Columbia

Abstract A 2-yr study was conducted at Black Belt Research and Extension Center in Marion Junction, AL, to evaluate the effect of nitrogen (N) fertilizer application rate on forage production characteristics, nutritive value, and animal performance of beef heifers grazing a mixture of native warm-season grasses (NWSG) including big bluestem, little bluestem, and indiangrass. Six, two-hectare plots were randomly assigned to one of two treatments (0 or 67 kg N ha-1 applied in early April; n = 3 replications per treatment). Paddocks were continuously stocked with four weaned Angus × Simmental beef heifers (initial BW 288 ± 7 kg) from late May/early June through mid-to-late August during 2018 (73 grazing d) and 2019 (70 grazing d), respectively. Put-and-take cattle were used to manage forage to a target of 38 cm. Forage mass and canopy heights were collected every two weeks during the trial. Visual ground cover ratings, canopy light interception, and botanical composition were measured at the beginning and end of the trial in each year. Hand-plucked samples were collected every two weeks during the grazing trial to determine forage nutritional value. Data were analyzed using the PROC MIXED procedure in SAS 9.4, and differences were declared significant when P ≤ 0.05. Nitrogen fertilized NWSG had greater crude protein (P < 0.0001), sward heights (P = 0.0003), and canopy light interception at the beginning of the season (P = 0.0049) compared to non-fertilized paddocks. However, there were no differences (P ≥ 0.05) among N-fertility treatments for mean forage mass, heifer ADG, or BCS across the 2-yr study. Botanical composition data indicated that indiangrass decreased from 64% to 61% (P = 0.0022) and weed pressure increased from 11% to 15% (P = 0.0064) across the summer grazing season. Canopy light interception decreased by 51% from early June to August in fertilized NWSG and 26% in unfertilized paddocks, respectively. These data illustrate that NWSG systems may provide a viable grazing system in the summer months under reduced N inputs.
