Impacts Of Climate Change

Inland fisheries of arid and semi-arid regions of Africa are seriously threatened by negative impacts of climate change. Literature and several models show increase in temperature of 1.1oC in some areas. Sea level rise is projected to increase to 0.8 m by the year 2100. Fish yields have increased almost linearly by around half a million metric tons per decade over the past 60 years, while clear cyclical variations in the residuals of about 20 years' periodicity above and below the trend line have been observed. Although fisher folks, their communities, and local institutions are already constantly adapting to various forms of change, flimsiness in the wider governance and macro-economic environment has weakened the overall adaptive capacity of these regions and fishers are vulnerable to projected climate change. For significant benefits of inland fisheries to be accomplished, planned adaptation at scales from the local to the regional is very necessary.

SUMMARYStudies on climate impacts and related adaptation strategies are becoming increasingly important to counteract the negative impacts of climate change. In Ethiopia, climate change is likely to affect crop yields negatively and therefore food security. However, quantitative evidence is lacking about the ability of farm-level adaptation options to offset the negative impacts of climate change and to improve food security. The MarkSim Global Climate Model weather generator was used to generate projected daily rainfall and temperature data originally taken from the ECHAM5 general circulation model and ensemble mean of six models under high (A2) and low (B1) emission scenarios. The FAO AquaCrop model was validated and subsequently used to predict maize yields and explore three adaptation options: supplemental irrigation (SI), increasing plant density and changing sowing date. The maximum level of maize yield was obtained when the second level of supplemental irrigation (SI2), which is the application of irrigation water when the soil water depletion reached 75% of the total available water in the root zone, is combined with 30 000 plants/ha plant density. It was also found that SI has a marginal effect in good rainfall years but using 94–111 mm of SI can avoid total crop failure in drought years. Hence, SI is a promising option to bridge dry spells and improve food security in the Rift Valley dry lands of Ethiopia. Expected longer dry spells during the shorter rainy season (Belg) in the future are likely to further reduce maize yield. This predicted lower maize production is only partly compensated by the expected increase in CO2 concentration. However, shifting the sowing period of maize from the current Belg season (mostly April or May) to the first month of the longer rainy season (Kiremt) (June) can offset the predicted yield reduction. In general, the present study showed that climate change will occur and, without adaptation, will have negative effects. Use of SI and shifting sowing dates are viable options for adapting to the changes, stabilizing or increasing yield and therefore improving food security for the future.

Impacts Of Climate Change

In recent years, literary studies have become increasingly invested in environmentalism. As science reveals the negative impacts of climate change, and demonstrates a growing concern for humanity’s contribution, literature operates as a form of cultural documentation. It details public awareness and anxieties, and acts as a conduit for change by urging empathetic responses and rendering ecological controversy accessible.To explore the relationship between literature and environmental politics, this paper will focus on the work of science fiction writer Philip K. Dick, and his dystopian visions. In his particular brand of sci-fi, there is no future for humanity. Science and technology fail to pave the way for a better and fairer society, but rather towards, as far as Dick is concerned, extinction. He argues that scientific advancement distances us from reality and from a sense of “humanness”. His pessimistic futures are nihilistic but tender; nurturing a love for humanity even in, what he considers to be, its final hours.Unlike the work of other prominent sci-fi writers, Dick’s fiction does not look towards the stars, but is in many ways a return to earth. The barren landscapes of Mars and other planets offer no comfort, and the evolution of the human into cyborgs, androids and post human species is depicted as dangerous and regressive. Dick’s apocalyptic visions ground his readers in the reality around them, acting in the present for the sake of the earth and humanity’s survival. His humanism is critical of grand enlightenment ideas of “progressivism”, and instead celebrates ordinariness. In the shadow of corporate capitalism and violent dictatorial governments, Dick prefers the little man, the ordinary everyday domestic hero for his narratives. His fiction urges us to take responsibility for our actions, and prepares us for the future through scepticism and pessimism, and a relentless fondness for the human.

Abstract: Many informal settlements in Indonesia have been unable to survive, this is due to changes that occur in the neighborhood. This change resulted in the not surviving of informal settlements, but this did not affect the informal settlements in the city of Palangkaraya, settlements on the banks of the Kahayan river were even more developed, and began to develop towards the mainland.As climate change and the global environment increase, there is a tendency for people to conceptualize adaptation in residential buildings as a process of survival and how adaptation is practiced by people who face the negative impacts of climate change, for example in informal settlements on the Kahayan river bank, where residents adapt to building their homes to be able to withstand environmental changes. Where the neighborhood is located there are tides of the river, as well as other environmental factorsThis study is to find out how the Kahayan River settlement communities can survive, with changes that occur in the environment by analyzing using 6 strategies in building adaptation, namely: Adjustable, Versatile, Refitable, Convertible, Scalable, and Movable (Robert Schmid, 2009). Adaptation that occurs in these settlements, namely on building houses that follow climate change, times, and the environment.Keyword: Informal Settlements, Kahayan River Edge, Adaptation, Transformation.Abstrak: Permukiman Informal di Indonesia banyak yang sudah tidak dapat bertahan, hal ini di karenakan adanya perubahan yang terjadi di lingkungan permukiman tersebut. Perubahan ini berakibat tidak bertahannya permukiman informal, namun hal ini tidak mempengaruhi permukiman informal di Kota Palangkaraya, permukiman yang berada di tepi sungai kahayan ini malah semakin berkembang, dan mulai berkembang menuju ke daratan.Seiring dengan meningkatnya perubahan iklim dan lingkungan global, ada kecenderungan masyarakat untuk membuat konsep adaptasi pada bangunan rumah tinggal sebagai proses untuk bertahan dan bagaimana adaptasi dipraktikkan oleh orang-orang yang menghadapi dampak negatif perubahan iklim, sebagai contoh pada permukiman informal yang berada di tepi sungai Kahayan, di mana warga beradaptasi pada bangunan rumah mereka untuk dapat bertahan terhadap perubahan lingkungan. Di mana lingkungan permukiman ini terdapat pasang surut air sungai, serta faktor lingkungan lainnya.Penelitian ini untuk mengetahui cara masyarakat permukiman tepi Sungai Kahayan dapat bertahan, dengan perubahan yang terjadi di lingkungan dengan menganalisa menggunakan 6 strategi dalam adaptasi bangunan, yaitu: Adjustable, Versatile, Refitable, Convertible, Scalable, dan Movable (Robert Schmid, 2009). Adaptasi yang terjadi pada permukiman ini, yaitu pada bangunan rumah yang mengikuti perubahan iklim, jaman, dan lingkungan.Kata Kunci: Permukiman Informal, Tepi  Sungai Kahayan, Adaptasi, Transformasi.
