Invasive alien species (IAS) significantly impact biodiversity, human health, and economies, and considerable resources are often used to manage their spread. Few studies have focused on the human perception of IAS management, and little is known about approaches to improve stakeholder perception. This study examined perception gaps between managers and non-managers of a notorious weed Mikania micrantha and the preference for educational approaches to bridge those gaps. Household questionnaires and key informant interviews were conducted in the China-Myanmar Border Region (China), and ordinal logistic regressions and Wilcoxon rank sum tests were used in statistical analyses. We found a high level of perception of M. micrantha among stakeholders, and a significant influence of socio-demographic factors including gender, educational level, ethnic group, and geographical location. Scores of the identification, damage, control measure, and manual treatment of M. micrantha were significantly higher for managers than those for non-managers, indicating that there were certain perception gaps between two stakeholder groups. Nine educational approaches were identified as being effective in improving stakeholder perception of IAS, of which training workshops were mostly preferred, followed by brochures (or leaflets) and other promotional materials. Additionally, we propose that well-designed and well-conducted educational approaches would benefit stakeholder perception of IAS, and that integration of IAS management into a comprehensive rural development scheme would improve its long-term performance in marginalized rural communities.

Research into the human dimensions of invasive alien species (IAS) management has received great attention to date. However, little is known about how public education influences stakeholders knowledge and management of IAS. Using key informant interviews and household questionnaires, we explored the role of public education in farmers knowledge and management of invasive Mikania micrantha in the China-Myanmar Border Region (China). We found ten common educational approaches that farmers were familiar with and/or adopted, and a high level of knowledge and management among farmers. We also found that public educational approaches helped to improve farmers knowledge and management, with some differences due to socio-demographic factors. We conclude that promotional materials and training workshops work better than personal experience, and that training workshops perform best. These results suggest that improving the design and implementation of public education could contribute to effective communication among stakeholders and long-term management of IAS. Our findings provide important insights for adopting public education programs in IAS management.

Debris flows in mountain environments are among the most destructive natural hazards often leading to loss of human lives and economic damage. Understanding the public perception of debris flow hazards and associated adaptation measures generates theoretical and practical basis for disaster risk reduction in mountain environments. Based on household questionnaires and key informant interviews, we determined risk perception and management of debris flow events in the Upper Salween Valley Region, China, and implications for disaster risk reduction in marginalized mountain communities. Our findings demonstrated that farmers perceived heavy and frequent rainfall as a primary natural cause for debris flow events, and road construction as a major anthropogenic factor. In addition, farmers perceived a big threat and high occurrence probability of debris flow hazards. Farmers obtained information from television programs and local government to enhance their awareness of debris flow risks; they preferred living away from debris flow gullies and relying on help from neighbors to reduce risks. The government employed emergency cards to improve farmers’ emergency response capabilities, and manual early-warning systems to ensure risk management. This research indicates a long-term interaction between mountain communities and debris flow hazards, and a development perspective which integrates the development of disaster risk reduction strategies into rural development programs. Therefore, risk reduction of debris flows in marginalized mountain communities will benefit from the integration of farmer-based measures into government-led programs, and the implementation of a comprehensive rural development scheme.

Population-based studies on snow leopard (Panthera uncia) are of theoretical and practical significance for the conservation of alpine ecosystems, though geographic remoteness and isolation hinder surveys in many promising regions. The Sanjiangyuan National Park on the Tibetan Plateau is acknowledged as a main snow leopard habitat, but most of the region remains unexplored and unknown. We adopted a combined approach of route survey and camera trapping survey to explore the population density of snow leopard in the Yage Valley region of the Sanjiangyuan National Park. Results indicated that (1) large populations of blue sheep contributed to the major food supply for snow leopards, along with diverse prey species as dietary supplementations, and (2) a population density of four to six snow leopards per 100 km2 on the north bank was estimated, and nine to fourteen individuals within the valley core areas were identified. We also argue that under the potential impacts of hydropower dams, this valley ecosystem should be symbolized as a conservation hotspot and therefore merits prioritized conservation. We recommend further surveys combined with novel methods/techniques and advocate a sustainable ecotourism model for the first V-shaped valley along the Yangtze mainstream.

Irrigation systems are critical for food security and drought adaptation in mountainous areas. However, lack of funding and low efficacy of government-funded irrigation projects hinders irrigation infrastructure development. A public–private partnership (PPP) model is recommended for irrigation development, but its application in mountainous areas has not been well-documented and analyzed. Based on a case study of pumping station projects in the Lujiang Flatland in the Nujiang River Valley of Southwestern China, this paper aims to reveal the critical success factors of the PPP model in the development of agricultural irrigation infrastructure in mountainous areas. Results showed that the basic models of PPP projects in the study area can be described as follows: (1) private companies invested in and constructed pumping stations; (2) communities operated the stations; (3) farmers paid for the services; and (4) private companies profited from charging water fees, obtaining policy supports, or utilizing farmlands. The main success factors include: (1) rational project design according to local conditions; (2) multi-centered management mechanisms; (3) balanced cost- and risk-sharing mechanisms; and (4) building mutual trusts among stakeholders. This study offers applicable lessons and useful insights for irrigation water development projects and adaptation to drought in mountainous rural communities.

Agriculture is an important type of land use but suffers from drought, especially under global climate change scenarios. Although government is a major actor in helping farmers to adapt to drought, lack of funds has constrained its efforts. Public-Private Partnership (PPP) mechanism has been widely applied in urban infrastructure development to raise fund for public goods and services, but very few studies explored its role in rural areas. Based on interview of 139 farming households and open-ended interview of village heads, government officials and company representatives, in the Lujiang Flatland in the Nu River (Upper Salween) Valley, Southwest China, this paper aims to reveal how PPP functions to enhance farmers' adaptation to drought. We found that farmers have developed multiple strategies in their own ways to adapt to drought, including pumping and store water, using water-saving irrigation techniques, changing of crops, and strengthening water management at the community level, while insufficient funds, water resource scarcity and mismatch of time-scale of crop growth and drought even hindered their adaptation options. Limited fund sources, gap in policy implementation and weak performance of government-funded projects hindered governmental supports to be effective. Weak motivation and distrusted by farmers limited the engagement of private enterprises in supporting farmers to adapt to drought. PPP mechanism has the potential to mobilize fund from multiple sources, share costs, risks and benefits among different stakeholders, combine both scientific and local knowledge, and reduce uncertainty through formal and informal institutions. Benefited from these advantages, PPP mechanism could improve project performance, thus increase farmers’ adaptation options and resilience to drought. This study offers referential lessons and valuable insights for agricultural development, especially for mountain communities vulnerable to exceptional and recurrent drought episodes under warming climate.
