The Impact

The occurrence of the invasive apple snail Pomacea canaliculata in Indonesia was first reported in 1984. The species was introduced as an ornamental aquarium pet. Since then, people have begun to culture the snail in ponds usually adjacent to rice fields. When it was realized that the species multiplied rapidly and was a serious pest, this invasive apple snail had already spread widely. There are many cultural methods of controlling and preventing its distribution, but none are effective in keeping them at non-damaging levels. We mapped the distribution of P. canaliculata in Indonesia from the MZB’s collections as well as literature references and found that the snail invaded almost all large islands, such as Sumatra, Java, Kalimantan, Sulawesi, Maluku, and West Papua. We also studied the impact of P. canaliculata on the native apple snails P. ampullacea, P. scutata, and P. virescens in Lake Rawa Pening (a popular tourism destination) as a case study. The results showed that two species of Pila already disappeared from Lake Rawa Pening. Only P. scutata occurs still in the region and was found alive usually in shallow water and rice fields surrounding the lake. To resolve the problem we recommend that cleaning the lake periodically from the invasive aquatic weed Eichhornia crassipes (known to locals as “eceng gondok”) by a private company and harvesting the weeds for the local small craft industry by the local fishermen could be an alternative measure to reduce the population of the P. canaliculata, as well as collecting P. canaliculata for local food or for feeding ducks. Rearranging the number of fish-pens “karamba” and their location in the lake could be seen as an alternative way also for reducing the population of P. canaliculata, since the snails lay their egg masses on the bamboo stakes of “karamba.” Such rearrangement could make the landscape more attractive for tourism.

The Impact

<p>Over the last two decades, Indonesia began to implement Public-Private Partnerships (PPPs) to provide an alternative mechanism for providing public infrastructure. The need to accelerate development, fulfil national demands and address mounting fiscal constraints are the reasons behind choosing PPP approach. One of the infrastructure projects using PPP mechanisms in Indonesia is Central Java Power Plant (CJPP) project, which is claimed to be the largest power plant in Southeast Asia. The project bidding was won by three consortia including ITOCHU Corporation, Adaro Power and J-Power, while the Government of Indonesia provided a guarantee for this project through the Ministry of Finance (MoF) and the Indonesia Infrastructure Guarantee Fund (IIGF). The project is built under Build, Operate, Own, and Transfer (BOOT) PPP model.  In continuing academic research about PPP in general and CJPP in particular, this study was conducted with the aim of exploring critical issues and challenges in implementing PPPs in CJPP project. Three issues were chosen for particular examination, including governance, environment and social issues. This study was conducted by adopting a qualitative approach under a constructivist epistemology to gain meaning and knowledge from certain phenomena or specific circumstances, in this case, by using CJPP as a single case study. Document reviews, semi-structured interviews, and unstructured observation were carried out from July to September 2018 to gain information and perspectives from multilevel stakeholders who are in charge, involved in and were impacted by the implementation of PPP mechanism in CJPP. Stakeholder Analysis and Sustainable Livelihood Approach were taken as the framework for data analysis.  This study found that top-down approach applied to implementing PPP in CJPP project left some governance issues and dynamics about power relations and regulations; conflicting stakeholders’ interests; communication and knowledge gaps; and dualism perspectives for viewing the scheme. The Governments of Central Java and Batang Regency underwent difficulties in structuring and implementing Environmental and Social Impact Assessment (ESIA), or in Bahasa Indonesia known as AMDAL. Meanwhile, coal, the major resource that will be utilised in this project, faces issues surrounding its emissions, stock, and sustainability. Several issues regarding five forms of capital for sustainable livelihood – human capital, social capital, economic capital, natural capital and physical capital – also arose during the project period. These issues included differing perspectives and sentiments among the surrounding societies and economic inequalities, as well as cultural and migration issues.  It is hoped that this research can inform our understanding of PPP implementation, both in policy and in practice. Based on this study, PPP practice at the national level should standardise documents and processes as well as having project assistance. At the regional level, the local government must be more empowered regarding their roles, responsibilities and resource management. Moreover, the impact of PPP on environment and society should be more precisely predicted and managed.</p>

Impact of coastal inundation on ecology and agricultural land use case study in central Java, Indonesia Focusing on the regional scale, this study provides information concerning the existing ecological problems associated with coastal inundation in the northern part of coastal area in Central Java Province, Indonesia. The objectives of this paper are to map the coastal inundation, to investigate the impact of coastal inundation on coastal environment and ecology, and to assess the impact of inundation on agricultural land use. An integration of techniques, namely neighborhood analysis, iteration operation, and superimposed analysis method has been applied to generate the digital map and to analyze the impact of inundation. Fieldwork measurement has been done using cross-profiling in order to observe the impact of inundation on the coastal ecosystem. Based on the scenario of 100 cm and 150 cm of inundation, the affected area is about 15 207.6 Ha and 16 687.31 Ha, respectively. Fishpond, dry farming and paddy field are the most affected agricultural areas due to coastal inundation.

The Impact

Considering the emerging global markets for the consumption of cashmere products, current sustainability issues prevailing in the traditional cashmere industry are explored in this study. To get a deeper understanding of the sustainability concerns in the cashmere industry, it is important to understand the cashmere supply chain operations to uncover the key sustainability issues prevalent in the present-day traditional cashmere industry. For this, a single case study was conducted in Kashmir, India using qualitative approaches. Data collection was carried out using semi-structured interviews, observations, cashmere retailer websites and documentary evidence. Due to the impact of mechanization and lack of industry standards, the research findings indicate deteriorating socio-economic conditions of the artisans; especially, women spinners and weavers. Mechanization promotes economic sustainability for the manufacturers and retailers which helps them strengthen their market base. However, with this, artisan communities are rendered jobless who are dependent on their manual skills for sustenance as they have limited alternate revenue generation options. Moreover, the lack of motivation among the artisans to use institutional support further escalates sustainability concerns in the traditional craft industry.

Abstract Following reports of an invasive snail causing crop damage in the expansive Mwea irrigation scheme in Kenya, samples of snails and associated egg masses were collected and sent to CABI laboratories in the UK for molecular identification. DNA barcoding analyses using the cytochrome oxidase subunit I gene confirmed the identity of the snails as Pomacea canaliculata, widely considered to be one of the most invasive invertebrates of waterways and irrigation systems worldwide. To the best of our knowledge, this is the first record of P. canaliculata in Kenya, and the first confirmed record of an established population in continental Africa. This timely identification shows the benefit of molecular identification when combined with a reliable database such as that provided by the Barcoding of Life Data system. We found that the egg masses tested gave an identical barcode sequence to the adult snails, allowing identifications to be made more rapidly. Given the impact of this species in Asia, there is need for an assessment of the risk to Africa, and the implementation of an appropriate response in Kenya and elsewhere to manage this new threat to agriculture and the environment.

Abstract Menara Kudus area marks the beginning of Kudus City, Central Java, Indonesia. The area is famous for its many historic buildings, including Menara Kudus, Al Aqsa Mosque, the traditional Kudus house, and Sunan Kudus tomb complex. Menara Kudus area is an area visited by pilgrims and tourists. In addition, there are many “pesantren” in the surrounding area that make this area never look deserted. Economic development thrives around the area but doesn’t necessarily change physical setting. This study was designed to describe the impact of historic buildings in Menara Kudus area on the sustainability of the surrounding area. The method used in this research is qualitative interpretive descriptive, which analyzes field data using 3 aspects of sustainability which is economic, social and environmental fields. The analysis phase is carried out through 3 stages. The first stage is the explanation and description of historic buildings around the Holy Tower. The second stage, discuss and describe the economic, social, and environmental aspects around the Menara Kudus. The third stage, interpretation to see the impact toward surrounding area. The results of this study show there are significant influence between historic buildings and the sustainability of the area, especially on the economic aspect. Crowds of pilgrims and tourists visiting the Menara Kudus area make economic activity in the surrounding area flourish. Likewise, with the presence of “santri” from outside the Kudus area which is in the vicinity of Menara Kudus. The existence of a institution that manages the Mosque, the Tomb, and Menara Kudus and the Kudus Cultural Heritage Team makes this area neatly arranged so that it supports the sustainability of the region.

Migration is one way for villagers in Bangkalan District to survive and improve their lives. Availability of employment and differences in the level of wages received in migrant areas are attractive factors, while the condition of villages in terms of physical capital, human capital, financial capital and natural capital which are less than ideal are the driving factors for migrating. This study examines the impact of the Suramadu bridge on the number of villagers migrating internationally using Village Potential data in 2007 and 2017 along with the factors that influence villagers to migrate internationally. Data were analyzed using tobit regression. The existence of the Suramadu bridge was not able to reduce the interest of the population to migrate internationally, instead it even increased the interest of the population to migrate internationally. Before the Suramadu bridge was operational, the existence of rice fields, building area, program credit, non-agricultural business, educational facilities and superior products reduced the interest of villagers to migrate internationally. After the Suramadu bridge operated, the existence of rice fields, building area and skills facilities reduced the interest of villagers to migrate internationally and the presence of poor people in the village increased the interest of residents to migrate.
