<p>Climate change is characterized by an increasing in temperature, drought, and an increase in CO2. This paper aims to propose the right strategy to deal with climate change in forage crops. Plant adaptation mechanisms include increasing water content, cell membrane stability, and photosynthetic capacity by suppressing stomata conductance and C consumption through respiration. The impacts of climate change on animal feed crops include: decreased productivity and nutrient content, and reduced planting area which affects the supply of animal feed so that food availability is disrupted. Adaptation strategies are carried out by managing the cultivation of forage plants, including selecting planting and harvesting times, as well as irrigation. Besides, it is necessary to select adaptive fodder plants through breeding. Breeding methods are conducted through the exploration of genetic resources to compile new superior forage adaptive crops to climate change. Recommendations for adaptable forage include: sorghum, <em>Brachiaria humidicola</em>, Napier grass (<em>Pennisetum purpureum</em>).</p>

<p>Coconut plantation area in North Sulawesi is an ecological basis for cattle but lower in terms of productivity of feed d annutrients. This study aims to improve the productivity of feed and nutrient  for beef cattle development in the coconut palm plantation through the introduction of superior forage P. purpureum Schum cv. Mott. The study was conducted from July 2012 to January 2013, in the Ongkaw Village, South Minahasa Regency, North Sulawesi. Coconut palms used in this study was 50 years-old tall coconuts with planting system of  9 m x 9 m at farmer plantation area. The research followed a completely randomized design with three treatments and three replications. The treatments tested were types of animal feed, which consists of (1). P. purpureum  Schum cv. Mott  (dwarf elephant grass),  Cynodon sp. (native grass), and P. purpureum (forage elephant grass). Planting systems of livestock forage are 20 cm x 20 cm, for Cynodon sp.  100 cm x 50 cm for  both  P. purpureum  Schum cv. Mott and P. purpureum. The first defoliation was done 70 days after planting, after that, the defoliation was done every 45 days. The result showed that the dry weight of animal feed/ha was 15.31 tons, 163.73   tons and 128.21 tons for Cynodon sp., P. purpureum  Schum cv. Mott and P. purpureum, respectively. Dry matter and nutrients of P. purpureum  Schum cv. Mott was higher than that of Cynodon sp. and P. purpureum. The result showed that the introduced P. purpureum  Schum cv. Mott significantly increased both animal feed production and feed nutrients in coconut plantation area as compared to the local forage crops (Cynodon sp. and P. purpureum). The P. purpureum  Schum cv. Mott can adapt to the shade of bearing coconut palms.</p><p>ABSTRAK </p><p>Lahan perkebunan kelapa di Sulawesi Utara merupakan basis ekologi sapi namun produktivitas dan nutrisi pakan rendah.

Abstract. Livestock numbers are increasing to supply the growing demand for meat-rich diets. The sustainability of this trend has been questioned, and future environmental changes, such as climate change, may cause some regions to become less suitable for livestock. Livestock and wild herbivores are strongly dependent on the nutritional chemistry of forage plants. Nutrition is positively linked to weight gains, milk production and reproductive success, and nutrition is also a key determinant of enteric methane production. In this meta-analysis, we assessed the effects of growing conditions on forage quality by compiling published measurements of grass nutritive value and combining these data with climatic, edaphic and management information. We found that forage nutritive value was reduced at higher temperatures and increased by nitrogen fertiliser addition, likely driven by a combination of changes to species identity and changes to physiology and phenology. These relationships were combined with multiple published empirical models to estimate forage- and temperature-driven changes to cattle enteric methane production. This suggested a previously undescribed positive climate change feedback, where elevated temperatures reduce grass nutritive value and correspondingly may increase methane production by 0.9 % with a 1 °C temperature rise and 4.5 % with a 5 °C rise (model average), thus creating an additional climate forcing effect. Future methane production increases are expected to be largest in parts of North America, central and eastern Europe and Asia, with the geographical extent of hotspots increasing under a high emissions scenario. These estimates require refinement and a greater knowledge of the abundance, size, feeding regime and location of cattle, and the representation of heat stress should be included in future modelling work. However, our results indicate that the cultivation of more nutritious forage plants and reduced livestock farming in warming regions may reduce this additional source of pastoral greenhouse gas emissions.

A trial was conducted to investigate the germination percentage and emergence potential of nine imported temperate forage germplasms at the National Animal Production Research Institute, Shika, Nigeria. The seeds consisted of seven grasses namely; Beefsteak plant (Fructus perillae), Sweet elephant grass (Pennisetum alopecuroides), Wild foxtail millet (Setaria viridis), Napier grass (Pennisetum purpureum), King grass (Pennisetum sinese), Chinese sorghum (Sweet sorghum) and Zea mexican schard (Purus frumentum) and two legumes namely; Chinese woad (Isatis tinctoria) and Chinese alfalfa (Medicago sativa). A laboratory germination test and pot emergence trial was carried out to ascertain their viability. The result of the experiment showed that Sweet elephant grass, napier grass and king grass recorded over 90 % germination and the least was 30 % in Chinese sorghum. Chinese alfalfa and wild foxtail millet had least germination percentage with 100 % Seed dormancy.Highest emergence rate, seedling length and seedling vigour indexwere observed in king grass than the other forage germplasms. The highest percentage emergence was obtained in king grass > sweet elephant grass > napier grass > Zea mexican schard > beefsteak plant > Chinese woad > Chinese sorghum, respectively. It was concluded that these forages can successfully be adopted as animal feed resources in Nigeria and therefore, recommended formulti-locational trials in all the ecological zones of the country.

Complex Subject

Climate change is a complex subject with terms and definitions that can seem overwhelming to non-specialists. What is ‘albedo’? What does ‘radiative forcing’ mean? What does ‘geoengineering’ entail? As climate change impacts grow more frequent and intense, it is critical that journalists, in particular, are equipped with the right information when they report. This set of open-access multilingual glossaries aim to bridge the gap between research and the general public by compiling this comprehensive list of most frequently-used terms related to climate change. A majority of these terms have been sourced from the different IPCC reports as well as public platforms such as the BBC and the Climate Reality Project.

The Right

Many in the environmental movement have argued in recent years that in order to speed up climate actions we should take the ethics out of the climate change debate. Focusing on the moral obligation to act or on the effects of climate change on the most vulnerable was often judged to render the discourse too “heavy,” “negative,” or “difficult.” Many also deemed it unnecessary. After all, renewable energies, better designed cities that allow for reduced car use, and power plant regulations that lead to cleaner local air—to take just three examples—all have real and substantial benefits unrelated to the fact that they are “the right thing to do” in the face of climate change. They create jobs, reduce health problems and costs, and make society fitter.

Parasite Challenge

AbstractLevels and seasonal patterns of parasite challenge to livestock are likely to be affected by climate change, through direct effects on life cycle stages outside the definitive host and through alterations in management that affect exposure and susceptibility. Net effects and options for adapting to them will depend very strongly on details of the system under consideration. This short paper is not a comprehensive review of climate change effects on parasites, but rather seeks to identify key areas in which detail is important and arguably under-recognized in supporting farmer adaptation. I argue that useful predictions should take fuller account of system-specific properties that influence disease emergence, and not just the effects of climatic variables on parasite biology. At the same time, excessive complexity is ill-suited to useful farm-level decision support. Dealing effectively with the ‘devil of detail’ in this area will depend on finding the right balance, and will determine our success in applying science to climate change adaptation by farmers.

The North

The official variety trials at Rovaniemi, Finland (66.58°N, 26.01°E) in 1980–2017 show a substantial increase in dry matter yields (DMY) of timothy (Phleum pratense), meadow fescue (Festuca pratensis) and tall fescue (Festuca arundinacea), coinciding with a 156 °Cd increase in the average growing season Tsum and a 461 °Cd decrease in the average winter frost sum for the same period. The annual DMY of timothy was 3128, 4668, 8385 and 9352 kg ha-1 in the periods (P) 1980–1989 (P1), 1990–1999 (P2), 2000–2009 (P3), and 2010–2017 (P4). The first cut yielded 1792, 2166, 4008 and 4473, and the second cut 1337, 2503, 4378 and 4879 kg ha-1, respectively. Yields of meadow fescue followed a similar pattern. The first cut was about ten days and the second cut about one week earlier on P4 than on P1. Shorter snow cover period, milder winters, higher live ground cover of timothy in spring, and higher temperature sum during the growing season were most likely responsible for the yield increase. The results indicate a strong impact of climate change on DMY of perennial forage crops in the north.
