Qualifier Seminar by Mr Nugroho Christanto Dept. of Earth Systems Analysis, ITC Analyzing the driving factors of land degradation of a watershed in Java: integrating land use changes and weather variability

Java, the most populated island in Indonesia, experiences much environmental stress from its increasingly intensive agricultural use. Massive conversion from forest into cultivated land is a consequence of rising population. The need of food has forced the land conversion and expansion of agricultural land. Two driving factors have a direct effect on the land degradation in Java: land use changes and the occurrence and variability of extreme rainfall events. Land degradation manifests itself in the Serayu watershed as severe soil erosion, leading to a loss of fertile soil, damage to crops and gullying, and the occurrence of landslides that threaten lives and property. Apart from these onsite effects there are also off site effects: the occurrence of mudfloods and siltation of a dam downstream. Over the years agricultural expansion has lead to deforestation on the steeper slopes, and systems of terraces are built for agricultural crops. The efficiency of these terraces is not clear: they may prevent runoff because of the decreased slope, but may become prone to sliding when saturated. An analysis of land use change, relief and soil characteristics leads to identification of hazardous areas. However, to quantify the on-site and off-site effects and predict where and when soil erosion and landslides occur, two more things are needed: knowledge on the spatial variability of rainfall during extreme events, and dynamic hydrological modeling as a tool to bring all factors together. Information on spatial rainfall is available through meteosat satellite images and derivative products. Although they have a low spatial resolution, their temporal resolution is high and they can be used to analyze likely locations of rainfall which will be integrated with the hydrological modeling. This analysis should lead to a reduced risk for the people and design better soil and water conservation strategies. To improve land degradation analysis, the influence of land use will be analyzed. Coupling land-use landscape processes will be applied. In combination with rainfall distribution analysis (from remote sensing data), identifying of area prone to landslides and soil erosion will be improved by means of where exactly something happens and simulation of on and off site effects. In order to achieve that, coupled land degradation and land-use change modeling, CLUE-s, will be applied. Keywords: Java, land degradation, landuse change, weather variability


TERUNTUK IBUKU (puisi yang tak pernah tersampaikan..)

Masih saja aku tak mampu membuka mata.
Masih terlena dalam simfoni untaian desir-desir mimpi.
Disini aku jauh darimu.
Disini aku,…
Jauh di Eropa.

Terbaring aku disamping perapian…
Melayangkan aku pada sebuah impian…
Impian tentang Ibuku…
Di mana dalam pejaman mataku, Senyummu masih dapat ku lihat….
Di mana dalam khayalku, Kamu tetap ada bersamaku….
Biarkan saja sang embun pagi cemburu,
Asal kau tetap ada mencintaiku…
Berteman impian dan harapan…

Disini anakmu setengah mati merindumu..
Mendamba belaian sayangmu..
Menginginkan hangatnya pelukmu..
Aku merindumu..
Bercerita tentang masa kecilku…
Bercerita tentang harapan-harapan dan kasih sayangmu..

Partnerships for Reducing Landslide Risk: Assessment of the National Landslide Hazards Mitigation Strategy

landslideLandslides occur in all geographic regions of the nation in response to a wide range of conditions and triggering processes that include storms, earthquakes, and human activities. Landslides in the United States result in an estimated average of 25 to 50 deaths annually and cost $1 to 3 billion per year. In addition to direct losses, landslides also cause significant environmental damage and societal disruption. This report reviews the U.S. Geological Survey’s (USGS) National Landslide Hazards Mitigation Strategy, which was created in response to a congressional directive for a national approach to reducing losses from landslides. Components of the strategy include basic research activities, improved public policy measures, and enhanced mitigation of landslides. The NRC report commends the USGS for creating a national approach based on partnerships with federal, state, local, and non-governmental entities, and finds that the plan components are the essential elements of a national strategy. The report recommends that the plan should promote the use of risk analysis techniques, and should play a vital role in evaluating methods, setting standards, and advancing procedures and guidelines for landslide hazard maps and assessments. The NRC panel suggests that substantially increased funding will be required to implement a national landslide mitigation program, and that as part of a 10-year program the funding mix should transition from research and guideline development to partnership-based implementation of loss reduction measures.

Earth Science and Applications from Space

51YNOCJ0ZdL._SS500_Understanding the complex, changing planet on which we live, how it supports life, and how human activities affect its ability to do so in the future is one of the greatest intellectual challenges facing humanity. It is also one of the most important challenges for society as it seeks to achieve prosperity, health, and sustainability.

These declarations, first made in the interim report of the Committee on Earth Science and Applications from Space: A Community Assessment and Strategy for the Future,1 are the foundation of the committee’s vision for a decadal program of Earth-science research and applications in support of society—a vision that includes advances in fundamental understanding of the Earth system and increased application of this understanding to serve the nation and the people of the world. The declarations call for a renewal of the national commitment to a program of Earth observations in which attention to securing practical benefits for humankind play an equal role with the quest to acquire new knowledge about the Earth system.

The committee strongly reaffirms these declarations in the present report, which completes the National Research Council’s (NRC’s) response to a request from the National Aeronautics and Space Administration (NASA) Office of Earth Science, the National Oceanic and Atmospheric Administration (NOAA) National Environmental Satellite Data and Information Service, and the U.S. Geological Survey (USGS) Geography Division to generate consensus recommendations from the Earth and environmental science and applications communities regarding (1) high-priority flight missions and activities to support national needs for research and monitoring of the dynamic Earth system during the next decade, and (2) important directions that should influence planning for the decade beyond.2 The national strategy outlined here has as its overarching objective a program of scientific discovery and development of applications that will enhance economic competitiveness, protect life and property, and assist in the stewardship of the planet for this and future generations.

Prinsip hidup orang jawa

Orang jawa memegang beberapa prinsip hidup yang digunakan sebagai tutuntunan. Saya akan mencoba berbagi beberapa prinsip hidup yang diajarkan oleh Mendiang Nenek dan Mendiang Ibu saya. Semoga bermanfaat.

Datan serik lamun ketaman, datan susah lamun kelangan.

Arti: Datan = jangan, Serik=sakit hati, lamun=walaupun, ketaman=disakiti, susah=sedih, kelangan=kehilangan

“Jangalah sakit hati walau tersakiti, janganlah sedih walau kehilangan”

Ibu dan nenekku selalu mengajarkan untuk ikhlas, mereka selalu member wejangan “ojo bungah-bungah banget yen lagi seneng, ojo susah-susah banget yen lagi keno cobo”. Inti dari prinsip hidup ini bisa jadi adalah Ikhlas, yang berakar pada 2 , Ikhlas akan takdir dan Ikhlas akan pilihan. ikhlas akan takdir.. artinya bahwa hidup kita telah digariskan… dan kita sedang bermain peran dalam hidup ini…kita harus ikhlas menjalaninya… sedangkan Ikhlas akan pilihan: artinya… dalam hidup kita selalu dihadapkan dengan pilihan… bahkan pilihan yang simple.. mandi atau engga’, makan nasi apa mie dll…. dan kita harus ikhlas memilih… dan jika sudah memilih… perjuangkan pilihan kita. Kalo kita bisa ikhlas, kita tidak akan sakit hati (serik) walau tersakiti (ketaman), dan tidak akan larut dalam kesedihan (susah) walau kehilangan (kelangan)
