Boundaries, limits, landscapes and flows: An analytical framework for boundaries in natural resource management.

In times of increasing pressure on natural resources, resource boundaries have become more ambiguous. Resources are increasingly interlinked, and competing users may define a resource and its boundaries differently. At times, resource units are confined into "resource plots", while at other times they are "resource stocks".

Seeding the clouds to reach the sky: Will China's weather modification practices support the legitimization of climate engineering?

In this Perspective, we discuss whether in times of quickly proceeding global environmental change, radical global interventions like "climate engineering" may gain legitimacy in China and eventually be deployed or supported. We argue that one cornerstone for whether climate engineering, and solar radiation management in particular, could gain legitimacy in China, is its current weather modification programme. In China, weather modification is institutionalized and deployed on a large scale, and current narratives around the legitimacy to intervene into the local climate may provide a rationale for interventions such as solar radiation management.

Overcoming the Challenges of Water, Waste and Climate Change in Asian Cities.

Unprecedented challenges in urban management of water, waste and climate change-amplified by urbanisation and economic growth-are growing in Asia. In this circumstance, cities need to be aware of threats and opportunities to improve their capacity in addressing these challenges. This paper identifies priorities, barriers and enablers of these capacities.

Mitigating land pollution through pesticide packages - The case of a collection scheme in Rural China.

Pesticide packages that are discarded on agricultural land can contaminate water bodies and pose a threat to the environment and human health. Little is known about how developing countries deal with this kind of land pollution. While in developed countries, packages are collected by professional organizations, the smallholder context in developing countries makes the collection of this waste much more difficult.

Environmental potentials of policy instruments to mitigate nutrient emissions in Chinese livestock production.

To minimize negative environmental impact of livestock production, policy-makers face a challenge to design and implement more effective policy instruments for livestock farmers at different scales. This research builds an assessment framework on the basis of an agent-based model, named ANEM, to explore nutrient mitigation potentials of five policy instruments, using pig production in Zhongjiang county, southwest China, as the empirical filling. The effects of different policy scenarios are simulated and compared using four indicators and differentiating between small, medium and large scale pig farms.

Managing manure from China's pigs and poultry: the influence of ecological rationality.

We have investigated manure management practices at three farm scales in Chinese pig and poultry production. The concept of ecological rationality was employed to explore empirically how environmental concerns drive adoption of environmental-friendly manure management technologies at different farm scales. The more developed Rudong County in Jiangsu Province and the less developed Zhongjiang County in Sichuan Province were chosen as cases for study of 258 animal breeders.
