气候变化对青藏高原水资源安全的影响

青藏高原不仅是世界屋脊、亚洲水塔和地球第三极,也是中国重要的生态安全屏障和战略资源储备基地,更是资源政治与地缘政治的结合之处。青藏高原是世界上第三大淡水资源“储存库”,气候变化会加速高原地区的冰川消融,改变跨国界河流径流量的年度和季节性变化,增加水资源分配模式的不稳定性,从而加剧地区性水资源稀缺性危机,使地区性洪涝灾害增多,水治理难度提升。气候变化对青藏高原水资源安全的影响会产生连锁性的政治、经济与安全效应,不仅影响高原地区国家的水力开发计划与基础设施安全,加剧地缘政治博弈的复杂性,而且影响中国的海外水电投资,使中国的“一带一路”倡议和水利“十三五”发展规划的实施面临更多的国际压力与挑战。在气候变化的影响下,青藏高原水资源安全涉及十几亿人口的生存和发展问题,涉及亚洲的稳定与和平。对此,中国应积极实践构建人类命运共同体理念,在青藏高原水资源安全的维护上扮演更重要的角色,一方面在技术层面上加强对青藏高原水资源安全动态的深度调查与持续性跟踪研究,另一方面在政治层面上推动高原地区国家的气候治理合作与区域合作框架构建。     

Demands,responsibility, and influence in Malawi’s participatory agricultural extension services

Participatory governance offers the potential to deliver responsive and accountable services. This article tests this expectation by looking at how members of participatory extension platforms in Malawi understand the meaning of “demand-driven” services, and allocate responsibility and influence in service provision. Results show that most respondents agree on bottom-up extension services that respond to expressed farmers’ needs (86% of respondents), and assign responsibility and influence widely across state and non-state actors. While these findings suggest that these participatory mechanisms can promote responsiveness to farmers’ needs and accountability, they also point toward different governance challenges in extension services.     

Changing knowledge and perceptions of African indigenous vegetables: the role of community-based nutritional outreach

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.     

Opening up to OERs: Electronic Original Sourcebook Versus Traditional Textbook in the Introduction to American Government Course

Traditional American Government textbooks are expensive and often unpopular with students. New technologies and Open Educational Resources (OERs) open up the potential for change, but questions of quality are ever present: can OERs really help students learn better, or are they just cheaper? I developed an OER based on original sources and compared student learning outcomes with the OER section to those in a free digital textbook section. While the OER I created did not work as well as I had hoped, I nonetheless developed a redesign of my course and my approach to teaching, which is the true benefit of adopting OERs.     

The Malian fertiliser value chain post-subsidy: an analysis of its structure and performance

This article examines the structure of the Malian fertiliser value chain and its performance in the context of the national subsidy programme, drawing on a review of the literature, farm household survey, and interviews with fertiliser suppliers. It finds that participants in the subsidy programme use more fertiliser and have significantly higher yields. The number of wholesalers and retailers has risen, but procurement remains concentrated. Poor fertiliser quality is a recurrent problem. The high cost of the programme raises questions regarding its sustainability. Mixed performance reflects the need for better monitoring and evaluation, and transparency in the programme.     

“The pluses of pulses”: haricot beans and women’s empowerment in Ethiopia

This practical note demonstrates the role that haricot beans play in assisting women to become food and nutrition secure, to generate income, and to have sustainable livelihoods that are resilient to shocks. Based on qualitative research among female and male beneficiaries of a pulse innovation project implemented in southern Ethiopia, the note provides a summary of the critical voices of farmers, and the role that haricot beans play in empowering women. It also outlines some of the challenges that the project faced in achieving its empowerment objectives.     

Enabling collaborative synthesis in multi-partner programmes

Multi-partner consortia have emerged as an important modality for knowledge generation to address complex sustainability challenges. Establishing effective multi-partner consortia involves significant investment. This article shares lessons from the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), which aims to support policy and practice for climate change adaptation through a consortium model. Key lessons include the need to facilitate collaborative spaces to build trust and identify common interests, while accepting that this is not a guarantee of success; the importance of programmatic leadership to achieve synthesis; and the value of strategic planning in supporting motivation and alignment between partners.     

Investing in multi-stakeholder dialogue to address natural resource competition and conflict

How can multi-stakeholder dialogue help assess and address the roots of environmental resource competition and conflict? This article summarises the outcomes and lessons from action research in large lake systems in Uganda, Zambia, and Cambodia. Dialogues linking community groups, NGOs and government agencies have reduced local conflict, produced agreements with private investors, and influenced government priorities in ways that respond to the needs of marginalised fishing communities. The article details policy guidance in four areas: building stakeholder commitment, understanding the institutional and governance context, involving local groups in the policy reform process, and embracing adaptability in programme implementation.     

What encourages households to adopt rice as a new crop? Understanding gender roles and perceptions in households in northern Namibia

This article investigates how the introduction of new crops influences intra-household decision-making among the Ovambo in northern Namibia where women are responsible for crop farming, while men are engaged in livestock farming. It examines gender relations that underlie daily activities. The findings of the study show that women try new crops on their own or with the help of their children and do not negotiate with their husband, mothers, or brothers over household resources such as land, labour, and the cash of other family members. Women avoid conflicts with family members, but may have an increased perception of contribution to the household if they succeed in introducing new crops.     

Indicators for economic vulnerability to drought in South Africa

This article identifies and estimates economic drought vulnerability indicators among communal farmers in South Africa, using an economic vulnerability index based on a household survey of 121 communal farmers. The results show that lack of resources, unemployment, price sensitivity, market access, the level of farm debt, output, on- and off-farm diversification, management, and financial safety nets were the main economic vulnerability variables. Farm debt and financial safety provide the bulk of the vulnerability index. The study’s findings suggest that government should reconsider priorities in the implementation of appropriate policy measures in response to drought.
