Sustainability has become a primary goal for much of the legislation which governs resource management in New Zealand. A major difficulty associated with sustainable development objectives, however, is the absence of reliable indicators to measure progress towards the goal of sustainability. The ‘ecological footprint’ provides an estimate of the amount of ecologically productive land required on a continuous basis to sustain current levels of resource consumption and waste assimilation for a given population. By comparing the ecological footprint of a community with the amount of land available, we can more clearly determine whether our current consumption patterns are likely to be sustainable.
This paper explores the use of ecological footprint analysis within a New Zealand context. Modifications to the existing procedure for calculating an ecological footprint are proposed, and estimates based on the modified procedures are presented for New Zealand.
In Nepal, many rural households need access to public forest resources to complement private resources for food and livestock production. However, current forest policies are largely directed at Environmental protection. The first part of this study identified the effect of current forest policy on livestock production using survey data from 259 households in three Nepal hill districts. The second part used a forestry-agriculture integrated model to examine alternative land use policies that could increase household livestock holdings and income while maintaining the environmental services of the community forest. The results show that current forest policies contributed to reductions in potential household livestock holdings by 34% for goats, 30% for cattle and 27% for buffalo. This exacerbated problems of farm fertility and food shortages in vulnerable and poor households. Modeling of alternative policy scenarios indicates that livestock holdings and income could both be increased for most households in communities practicing agroforestry while still maintaining environmental protection. The increase could be highest for the poorest households. Finally, the article discusses potential implications of new environmental policies on local food security and sustainability in the country.
