The inverse farm size and productivity relationship (IR) is a recurring theme in the literature. However, most previous studies were undertaken within a setting of mixed cropping systems. In this article, we investigate the effect of farm size on productivity within the context of a perennial monocropping system, acute competition for farmland, frequent subdivision of farms and declining yields. We apply household survey data of smallholder tea farms in western Kenya and consider both technical efficiency (TE) and the yield per hectare as indicators of productivity.

Subsidies are part of the set of management tools that governments apply to modernize their fishing fleets and enable them to engage in offshore and international fisheries. Research has shown that subsidies often lead to overcapacity and overfishing, resulting in the depletion of fish stocks. A few studies, however, have found some positive effects for particular subsidies. In this paper, we investigate a credit-linked subsidy scheme in Vietnam, which seems to be justified on the basis of economic, social, and environmental considerations.

Payments for environmental services (PES) are considered an effective approach to solving both environmental and socio-economic issues. However, there lies a significant research gap in the context of their impact on income and attitudes toward conservation. Using household survey data and the propensity score matching technique, this study evaluates the impact of the payments for forest environmental services (PFES) program on household income and attitudes toward forest conservation in the Central Highlands of Vietnam.

Aquaculture is the fastest growing food production industry globally and is considered to have the greatest potential to meet the growing demand for seafood and being a solution to overfishing. Despite the benefits of aquaculture, the rapid growth and intensification of production (so-called conventional aquaculture) has raised concerns about food safety, fish welfare, and environmental and social issues stemming from a tragedy of the commons.
