Will buffer zones around schools in agricultural areas be adequate to protect children from the potential adverse effects of pesticide exposure?
California has proposed limiting agricultural pesticide use within 0.4 km of schools and childcare facilities. However, the 0.4-km buffer may not be appropriate for all pesticides because of differing toxicities, fate, and application methods. Living near pesticide use has been associated with poorer birth outcomes, neurodevelopment, and respiratory function in children. More research about exposures in schools, childcare facilities, and homes is needed. Despite incomplete science, this regulation is an important step to reduce potential exposures to children. The most vulnerable exposure period may be in utero, and future regulations should also aim to reduce exposures to pregnant women
Commodity Trade Stabilization Through International Agreements
We introduce a simple and efficient procedure for the segmentation of rigidly moving objects, imaged under an affine camera model. For this purpose we revisit the theory of "linear combination of views" (LCV), proposed by Ullman and Basri [20], which states that the set of 2d views of an object undergoing 3d rigid transformations, is embedded in a low-dimensional linear subspace that is spanned by a small number of basis views. Our work shows, that one may use this theory for motion segmentation, and cluster the trajectories of 3d objects using only two 2d basis views. We therefore propose a practical motion segmentation method, built around LCV, that is very simple to implement and use, and in addition is very fast, meaning it is well suited for real-time SfM and tracking applications. We have experimented on real image sequences, where we show good segmentation results, comparable to the state-of-the-art in literature. If we also consider computational complexity, our proposed method is one of the best performers in combined speed and accuracy. © 2011. The copyright of this document resides with its authors
Piscataqua Region Environmental Planning Assessment
The Piscataqua Region Environmental Planning Assessment (PREPA) was conducted to document the current status of environmental planning efforts and land use regulations for each of the 42 New Hampshire municipalities and 10 Maine municipalities (city and town governments) in the Piscataqua Region. The assessment involved analysis of over 80 questions associated with municipal regulatory and non-regulatory approaches to resource management. The assessment theme areas include land protection, wildlife habitat, stormwater management, erosion/sediment control, wetland and shoreland protections, floodplain management, and drinking water source protection, among others. Piscataqua Region Estuaries Partnership (PREP) staff and Land Use Team worked closely with a variety of stakeholders and the four regional planning commissions that service the Piscataqua Region on the development of the PREPA assessment form. For each of the 52 towns in the region, staff from the regional planning commissions reviewed municipal planning documents and interviewed key municipal representatives to complete an assessment form for each municipality. Data were collected in early 2009. This data was compiled by PREP into a database and analyzed for regional trends. Results for individual towns as well as regional trends are presented in this final project report. Differences between New Hampshire and Maine environmental policies are also evaluated for select issues pertaining to water quality and habitat protection

Developing conservation governance strategies: holistic management of protected areas in Nepal
The Buffer Zone (BZ) concept has been introduced in Nepal as a key component of the national biodiversity conservation strategy to mitigate the impacts of protected areas on local communities, and thereby reduce adverse impacts of local people on protected areas. Unlike traditional Buffer Zone programmes which are mostly limited to creating a protective layer and/or distributing economic benefits to local people, the Buffer Zone management approach in Nepal integrates livelihoods and conservation issues and their linkages in a more holistic and balanced manner. The programme has been successful in establishing a network of community institutions and in mobilising large numbers of local communities in conservation and community development. The research findings clearly indicate that the current Buffer Zone management approach based on park revenue sharing for community development has been successful in developing positive attitudes among local people towards protected areas. There is also evidence of improvement in the condition of forests and biodiversity in the Buffer Zone and a decrease in pressure inside the protected areas for basic forestry resources. The BZ communities also feel empowered by the Buffer Zone management programme. These outputs suggest that if properly designed, the Buffer Zone management programme can achieve both conservation and development objectives ensuring the long-term integrity of the protected areas.
At the same time, however, the research has also revealed that the existing incentives and institutional arrangements adopted in the Buffer Zone management programme were necessary but not sufficient to address present and potential challenges in Chitwan National Park. There is a need to use additional instruments to demonstrate Buffer Zone management as a viable conservation governance strategy to expand conservation into the areas beyond park boundaries ensuring greater stability of the Park. Any park management strategy seeking to make tangible impacts on conservation, livelihood and governance should have five elements, namely; incentive, empowerment, education, enforcement and integration (IEEEI); and appropriate policy and institutional frameworks to implement them in an integrated way. If issues such as inclusion, equity, empowerment and integration are properly incorporated into the policies and programmes of the Buffer Zone management, the Buffer Zone management strategy adopted in Chitwan could be promoted as a viable model for the sustainable management of protected areas situated in a human dominated landscape
Town of Milton Shoreland Protection Project
Mettee Planning Consultants (MPC) worked with the Milton Conservation Commission to evaluate and streamline the townâs water resource protection regulations. One of the outcomes was revision and passage of a Shoreland Protection Overlay District as part of the townâs zoning ordinance
An investigation of the evidence of benefits from climate compatible development
Climate change is likely to have profound effects on developing countries both through the climate impacts experienced, but also through the policies, programmes and projects adopted to address climate change. Climate change mitigation (actions taken to reduce the extent of climate change), adaptation (actions taken to ameliorate the impacts), and on-going development are all critical to reduce current and future losses associated with climate change, and to harness gains. In the context of limited resources to invest in climate change, policies, programmes, or projects that deliver âtriple winsâ (i.e. generating climate adaptation, mitigation and development benefits) â also known as climate compatible development â are increasingly discussed by bilateral and multilateral donors. Yet there remains an absence of empirical evidence of the benefits and costs of triple win policies. The purpose of this paper is therefore to assess evidence of âtriple winsâ on the ground, and the feasibility of triple wins that do not generate negative impacts. We describe the theoretical linkages that exist between adaptation, mitigation and development, as well as the trade-offs and synergies that might exist between them. Using four developing country studies, we make a simple assessment of the extent of climate compatible development policy in practice through the lens of âno-regretsâ, âlow regretsâ and âwith regretsâ decision making. The lack of evidence of either policy or practice of triple wins significantly limits the capacity of donors to identify, monitor or evaluate âtriple wins at this point in time. We recommend a more strategic assessment of the distributional and financial implications of 'triple wins' policies
"Encystation": Containment and Control in Israeli Ideology and Practice
The radical closure of Gaza serves here as an extreme example of a process of
isolation and immiseration of national enemies that is deeply rooted in Israeli
ideology and practices of state formation. I use encystation to reveal the dual
meaning of the termâthat of radical isolation of diseased elements and that of
protecting a fetus within a wombâand to show how the two meanings connect
with respective Israeli policies toward Palestinians and Jews. I suggest in closing
that the Oslo Accords have put in place mechanisms for the future imposition
on West Bank Palestinians of the same containment currently afflicting Gaz
