The Impact

Organophosphates are the most widely used insecticide class in agriculture. The effects of organophosphates on insectivorous birds can potentially reduce the capacity of these birds to regulate insect pest populations as well as jeopardizing the survival of vulnerable bird species in matrix habitats. In this study, we investigated the diversity of birds inhabiting commercial macadamia orchards in Australia and assessed community-wide exposure of birds to an organophosphate insecticide (trichlorfon). We also studied the impact of trichlorfon on arthropods, and how this affected bird activity. We used a novel approach, combining bird acoustic surveys, and three different arthropod trapping devices. Birds and arthropods were surveyed immediately before and after a trichlorfon application, in sprayed and unsprayed orchards, at six different sites. Surveys showed that trichlorfon applications produced no changes in bird activity, either at the species or community level. Only one species (Lichmera indistincta) showed a significant increase in acoustic activity after treatment. These results indicate that several (62) bird species, some of which have been noted as undergoing regional decline, are exposed to trichlorfon applications. Additionally, trichlorfon applications also produced rapid, negative impacts on certain arthropod groups, particularly spiders. Because almost (80%) of the bird species recorded in the study include arthropods in their diets, then arthropod contaminated by trichlorfon are likely consumed by these orchard-dwelling birds. We recommend that pest management should incorporate strategies to reduce wildlife exposure to toxic chemicals to meet the joint goals of crop production and wildlife conservation in structurally complex agricultural habitats.

<p>Introduced mammalian predators, namely possums, stoats and rats, are the leading cause of decline in native avifauna in New Zealand. The control of these species is essential to the persistence of native birds. A major component of mammal control in New Zealand is carried out through the aerial distribution of the toxin sodium monofluoroacetate (otherwise known as 1080). The use of this toxin, however, is subject to significant public debate. Many opponents of its use claim that forests will ‘fall silent’ following aerial operations, and that this is evidence of negative impacts on native bird communities. With the continued and likely increased use of this poison, monitoring the outcomes of such pest control operations is necessary to both address these concerns and inform conservation practice. The recent growth in autonomous recording units (ARUs) provides novel opportunities to conduct monitoring using bioacoustics. This thesis used bioacoustic techniques to monitor native bird species over three independent aerial 1080 operations in the Aorangi and Rimutaka Ranges of New Zealand.  In Chapter 2, diurnal bird species were monitored for 10-12 weeks over two independent operations in treatment and non-treatment areas. At the community level, relative to non-treatment areas, the amount of birdsong recorded did not decrease significantly in treatment areas across either of the operations monitored. At the species level, one species, the introduced chaffinch (Fringilla coelebs), showed a significant decline in the prevalence of its calls in the treatment areas relative to non-treatment areas. This was observed over one of the two operations monitored. Collectively, these results suggest that diurnal native avifaunal communities do not ‘fall silent’ following aerial 1080 operations.  The quantity of data produced by ARUs can demand labour-intensive manual analysis. Extracting data from recordings using automated detectors is a potential solution to this issue. The creation of such detectors, however, can be subjective, iterative, and time-consuming. In Chapter 3, a process for developing a parsimonious, template-based detector in an efficient, objective manner was developed. Applied to the creation of a detector for morepork (Ninox novaeseelandiae) calls, the method was highly successful as a directed means to achieve parsimony. An initial pool of 187 potential templates was reduced to 42 candidate templates. These were further refined to a 10-template detector capable of making 98.89% of the detections possible with all 42 templates in approximately a quarter of the processing time for the dataset tested. The detector developed had a high precision (0.939) and moderate sensitivity (0.399) with novel recordings, developed for the minimisation of false-positive errors in unsupervised monitoring of broad-scale population trends.  In Chapter 4, this detector was applied to the short-term 10-12 week monitoring of morepork in treatment and non-treatment areas around three independent aerial 1080 operations; and to longer-term four year monitoring in two study areas, one receiving no 1080 treatment, and one receiving two 1080 treatments throughout monitoring. Morepork showed no significant difference in trends of calling prevalence across the three independent operations monitored. Longer-term, a significant quadratic effect of time since 1080 treatment was found, with calling prevalences predicted to increase for 3.5 years following treatment. Collectively, these results suggest a positive effect of aerial 1080 treatment on morepork populations in the lower North Island, and build on the small amount of existing literature regarding the short- and long-term response of this species to aerial 1080 operations.</p>

Abstract We study the impact of anticorruption efforts on firm performance, exploiting an unanticipated corruption crackdown in China’s Heilongjiang province in 2004. We compare firms in the affected regions with those in other inland regions before and after the crackdown. Our main finding is an overall negative impact of the crackdown on firm productivity and entry rates. Furthermore, these negative impacts are mainly experienced by private and foreign firms, while state-owned firms are mostly unaffected. We present evidence concerning two potential explanations for our findings. First, the corruption crackdown may have limited bribery opportunities that helped private firms operate. Second, the corruption crackdown may have interfered with personal connections between private firms and government officials to a greater extent than institutional connections between state-owned firms and the government. Overall, our findings suggest that corruption crackdowns may not restore efficiency in the economy, but instead lead to worse economic outcomes, at least in the short run (JEL L2, M1, O1).

Keberadaan industri semen di Kecamatan Bayah seperti dua sisi mata uang logam, memiliki dampak positif dan negatif tertentu bagi masyarakat sekitar, khususnya terhadap mata pencaharian nelayan Bayah. Penelitian ini bertujuan untuk mendeskripsikan kondisi mata pencaharian nelayan sebelum dan sesudah adanya industri semen, dan mengidentifikasi strategi adaptasi untuk menjamin keberlanjutan mata pencaharian di kalangan nelayan. Metode yang digunakan yaitu deskriptif kualitatif dengan nelayan sebagai key informan. Data didapatkan melalui kuesioner, wawancara mendalam, Focus Group Discussion (FGD), dan observasi lapangan. Hasil penelitian menunjukkan bahwa masuknya industri semen (PT. Cemindo Gemilang) di Kecamatan Bayah membawa perubahan berantai, baik dari perubahan ekologis maupun kehidupan sosial ekonomi nelayan. Perubahan ekologis menyebabkan bergesernya daerah tangkapan ikan, perubahan ketersediaan produk perikanan sebagai modal utama, peningkatan biaya dalam mengakses sumber daya, dan berimplikasi pada pendapatan rumah tangga nelayan. Ketidakpastian penghasilan seringkali ditanggulangi dengan diversifikasi mata pencaharian, yang merupakan salah satu bentuk strategi nafkah ganda yang sudah dilakukan oleh nelayan Bayah sebelum adanya industri semen. Namun setelah adanya industri semen membuka peluang untuk bekerja di sektor non perikanan yaitu sebagai buruh pabrik dan kuli panggul di dermaga. Strategi adaptasi untuk menjamin keberlanjutan mata pencaharian dilakukan melalui adaptasi berupa penganekaragaman sumber pendapatan, penganekaragaman alat tangkap, perubahan daerah tangkapan, dan memanfaatkan hubungan sosial. Title: The Impact of the Cement Industry to the Livelihood System of Bayah Fishers The existence of cement industry in Bayah Sub-district is like two sides of the same coin, it has a positive and negative impacts for the surrounding community, especially on the livelihood of Bayah fishers. This study aims to describe the livelihood conditions of fishers before and after the cement industry exists in their village as well as to identify adaptation strategies to ensure the sustainability of fishers livelihoods. The study used descriptive qualitative method involving fishers as the key informant. Data were collected through questionnaires, in-depth interviews, FGD, and field observations. Results showed that the existence of cement industry (PT. Cemindo Gemilang) in Bayah Sub-district brought about a series of change toward ecological and socio-economic life of the fishers. Ecological change led to shifting of catchment areas, changes in the availability of fisheries product as their major capital, increased costs of access to resources, and implications toward household incomes. Uncertainty of income was frequently solved by varying livelihoods, and it was one of strategies that has been implemented by Bayah fishers even before the cement industry exists. However, the existence of cement industry has created job opportunity in non-fishery sector such as factory workers and dock porters. Adaptation strategies to ensure the sustainability of their livelihood are: diversification of sources of income, diversification of fishing gear, relocation of fishing area and empowerment of social relationship.

Development of Agricultural and allied activities can be achieved through various approaches of Information and communication (ICT) tools. Kisan Mobile Advisory system (KMAS) is one of ICT approaches for dissemination of agricultural technologies to the farming community through SMSs. KVK, Nagaon created a registered farmers group and information related to crop production, insect pest control, dairy and poultry farming, fishery and other marketing related information was sent to users in monthly basis for many years. A sample size of 100 registered farmers were selected for the study in order to examine the impact of KMAS for technology dissemination in Nagaon district.  With the help of Pretested scheduled with Simple Random sampling data were collected and analyze in percent analysis. The survey showed that majority of the farmers found agricultural information as increase in knowledge (41.00%), partially applicable (73.00%).  The overall impact of the KMAS was low About at 55 percent, medium at 38 per cent and high at 7 per cent. Further they suggested that messages on latest technologies should be served flowed by local language, voice messages.

Vehicle Market

Several studies document the potential for eco-labeling and marketing programs; however, they focused on inexpensive, frequently purchased items. We identify whether such programs can be effective with more expensive, durable goods. We isolate the impact of the program on consumers by analyzing responses to a survey administered before and after the program to independent samples of individuals residing in and out of the marketing area. We used both multivariate analysis of variance and regression approaches in the analyses. Few vehicle dealers participated in the eco-labeling portion and we find the eco-marketing component of the program led to only one positive outcome; individuals exposed to the marketing are less likely to think all vehicles pollute about the same when driven. This was one of the key misperceptions that the Maine Clean Car Campaign attempted to correct. However, we also found three negative impacts of the Campaign. Individuals exposed to the marketing viewed vehicle emissions as being a smaller contributor to Maine's air quality problems and had an increased perception that greener vehicles suffered from poor performance and were more expensive.

Although substantive agreement exists on the role of climate variability and food scarcity in increasing violence, a limited number of studies have investigated how food resources affect violent conflict. This article explores the complex linkages between climate variability, agricultural production and conflict onset, by focusing on the spatial distribution of crop production in a cross-country setting. We hypothesize that spatial differences in crop production within countries are a relevant factor in shaping the impact of climate variability on conflict in agriculturally -dependent countries. To test this hypothesis, we rely on high-resolution global gridded data on the local yield of four main crops for the period 1982–2015 and aggregate the grid-cell information on crop production to compute an empirical indicator of the spatial concentration of agricultural production within countries. Our results show that the negative impacts of climate variability lead to an increase in the spatial concentration of agricultural production within countries. In turn, the combined effect of climate extremes and crop production concentration increases the predicted probability of conflict onset by up to 14% in agriculturally dependent countries.

Introduction: Magnesium is very important nutrient and performs a significant part in development and formation of many sink organs like roots and seeds. Furthermore, its fertilization significantly affects yield and numerous physiological mechanisms in different horticulture crop species. Moreover, its deficiency caused germination and reduction in horticulture crop stand. Nevertheless, its adequate concentration by foliar application plays important role in biochemical and physiological processes of plants like proteins synthesis, metabolism of carbohydrates, enzymes activation and energy transferring. Worldwide, many of our horticulture crops are facing low yield and quality problem due to fertilizer application at inadequate rate. The current review focuses on the impact of foliar applied Mg on some important cultivated horticultural crops (sugar beet, tomato, banana, potato, spinach, cauliflower, cassava, garlic, green case, potus, cucumber and grapes). Review results: Our extensive review has demonstrated that magnesium is very important factor limiting horticulture crop production but its negative impacts can be reduced by foliar application of magnesium. Foliar application of Mg can be recommended for correcting deficiencies because foliar sprays have no long term residual effect and every time fresh applications must be given to each crop. Moreover, amount depends on the nutrient status of crop and soil.

This study investigated the impact of film dramas on the emotional and cognitive state of recipients, as well as mediating effects of different modes of film reception. Furthermore, associations between the modes of reception and individual favored coping strategies were examined. One hundred fifty nondepressive and nonsuicidal adults living in Austria watched one of three films featuring the death of the main character. Data on the viewers’ mood, inner tensions, self-esteem, life satisfaction, depression, suicidal tendencies, attitudes toward suicide, predominantly used modes of reception, and preferred coping strategies were collected with questionnaires that were handed out before and after seeing the movie. Results indicated that drama viewing was linked to both negative and positive effects: on the one hand, to a deterioration of mood as well as an increase of inner tensions and depression scores, and on the other hand, to a rise in self-esteem and life satisfaction as well as a drop in suicidal tendencies. The more a subject was involved in the film, the more pronounced were the negative impacts and the smaller were the positive reactions. The viewers’ preferred coping strategies were partly associated with the modes of reception: the more an individual preferred to seek social support when facing a problem, the more he or she identified with the drama’s protagonist and tried to find behavior patterns in the movie to improve his or her own life.
