    The thesis of this article is that the now extensive contemporary literature on the economics of property rights has generated more heat than light. Economists have invoked at least five distinct theories of ownership or property rights in their work. Unfortunately, authors frequently fail to acknowledge the existence of competing theories of property rights that stand as conceptual rivals to the theory that they, often implicitly, invoke.

    The objective of this study is to determine the financing impact of total expenditure on the use of agriculture inputs (fertilizers, labor, and pesticides), and the output of cotton, rice, beans, corn, soybean, and wheat in Brazil. We study the period 1976–2005. The analysis is based on duality applied to the production theory. The output supplies and conditioned input demands are estimated from a translog multi‐output, multi‐input restricted profit function, where the total production credit is used as proxy of the total expenditure.

    Farming and forestry are practices with clearly defined institutions, markets, and policies. These are not as clearly defined for agroforestry, a practice experiencing increased interest in the USA. This study examined the barriers preventing the adoption of agroforestry within a household level theoretical framework informed by transaction costs and multifunctionality, using survey data from 353 Missouri (USA) landowners.

    Bangladesh

    This study examined pollution and shrinkage of urban lakes in the rapidly urbanizing city of Dhaka, Bangladesh. A mixed‐method approach was employed, nested within the European Environmental Agency Drivers, Pressure, States, Impacts, Responses Framework and Environmental Systems Analysis tools (as stakeholder and functions analysis methodologies). A variety of stakeholders and policymakers were first interviewed, being asked to participate in an exercise identifying their perceptions of the greatest challenges facing urban lakes in Dhaka.

    The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and other actors in the agricultural sector.

    This article uses two representative household budget surveys from the Kyrgyz Republic to analyze factors influencing participation and returns from different types of nonfarm activities in 2005 and 2006. We use the double hurdle and Heckman models, which allow us to demonstrate that a number of variables has different effects on participation and income from nonfarm activities. For example, residing in remote areas and lack of capital are found to stimulate participation in nonfarm activities, but decrease nonfarm income.

    The independent island nations of the South Pacific have a rich and threatened terrestrial biota. Despite considerable investment of resources into conservation over the last three decades, biodiversity is dwindling and protected area systems remain inadequate. This lack of success is caused by important differences in cultural, economic, landownership, and social factors in developing Pacific Island countries, compared to developed nations that often fund conservation programs and plans.

    Mexique

    Habitat loss and fragmentation is one of the main causes of biodiversity loss. Rare species are generally thought to be more sensitive to habitat fragmentation than common ones as small populations become even smaller. We did a population genetic study on a rare bird, the Worthen's sparrow Spizella wortheni which is endemic to semi‐arid and arid regions of northeast Mexico. Its population numbers suffer greatly from the transformation of grassland into farmland that leads to a patchy distribution with locally small population sizes.
