This paper tests the hypothesis pertaining to the interdependencies between trade and environmental policies in the presence of industry/firm lobbies, which is captured through industry/firm size. For an unbalanced panel of manufacturing firms in India at the five-digit National Industrial Classification (NIC), 2008 for the period 2008–2019, I find that firm size has a positive and significant impact on trade policy. The same holds true for a subset of firms that are polluting in nature (based on the Central Pollution Control Board classification). It is found that larger firms have a greater influence on those trade policies that are set unilaterally by the government. Also, there is no empirical support in favour of trade and environment linkages in the Indian context. This could be due to the fact that these two policies come under the domain of independent ministries of the government. Moreover, environmental safety assumes less significance and tends to adversely affect the competitiveness of the manufacturing sector. Notwithstanding the fact that environmental regulations are in place, the enforcement and monitoring mechanisms are remarkably weak on account of weak environmental institutions.

It has been hypothesized that differentially applied environmental regulations create pollution havens, as firms will choose to invest in countries with lax environmental standards. Using a theoretical model of pest control adoption and an empirical spatial equilibrium model, we examine one such environmental regulation, a U.S. ban on methyl bromide, to determine if an agricultural pollution haven will be created in Mexico. Alterations in agricultural production location, trade patterns, and methyl bromide use are determined. We find that, under the assumptions held, Mexico will not dramatically increase its use of methyl bromide following the ban. Sensitivity analysis to this result is conducted.

This article identifies ways to overcome impediments to restoring natural features on developed shores where human-use functions are the dominant driving forces. Suggestions are made for (1) incorporating natural features and natural dynamism into beach nourishment projects; (2) addressing constraints in size and space; (3) reducing the impact of human actions and elements in the landscape; (4) integrating endangered species programmes; (5) overcoming impediments to implementing restoration projects; (6) conducting post-construction evaluations and actions; (7) obtaining public support; and (8) addressing regulatory issues. Beach nourishment projects can better mimic natural landforms, while protecting infrastructure and habitat, creating space for dunes, and providing sediment for dune building. Dunes can have more value as habitat if sub-environments representative of natural gradients are accommodated. Greater human effort will be required to maintain both dynamic and stable zones for habitat, and these zones may be restricted to smaller scales. Controls can be placed on human actions, such as raking the beach, driving on the beach, walking through the dune, emplacing more structures than necessary and introducing exotic vegetation for landscaping. Regulatory restrictions that now prevent environmentally friendly actions can be eased, and adaptive management and education programmes can be implemented.

The increased effort by Congress to reduce agriculture's adverse consequences on the environment has been focused almost entirely on changing agricultural production practices at the farm level Because the agricultural sector is highly integrated, attempts to change a specific industry within the sector, such as production, input supply, or processing, may have undesirable effects. Programs designed to achieve society's environmental objectives by forcing change in agricultural production practices will lead to increased frustration, new programs and regulations, and further conflict between society and farmers. To guarantee sustainability of U.S. agriculture into the next century, efforts to incorporate new social needs into production agriculture should include changes in the research agendas of public and private institutions, marketing grades and standards, and the institutions that support the agricultural producer.
