Combat Climate Change

The livestock sector is one of the fastest growing agricultural subsectors in Viet Nam, resulting in growing demand to sustainably dispose or re-use livestock waste. This research examined the current adoption of biogas digestion of livestock waste treatment at household farms in order to provide insights for policy towards effective implementation. A questionnaire survey was conducted in September 2019, with the participation of 120 livestock owners in Nghe An province, which focussed on accessing their perspectives on biogas and examination of factors impacting their decisions to utilize this technology. Most respondents determined biogas to be an attractive solution for improving the environment. However, several factors limited the development of biogas installation, including technical and financial barriers, awareness and capacity limitations, and financial support as the most significant of these. Government support and policies that encourage household biogas utilization as a sustainable energy source to combat climate change is recommended.

Global Threat

Climate change is a global threat to livestock sector to so many species and ecosystem in different parts of the world. Climate change, heat stress, and nutritional stress are the major intriguing factors responsible for reduced fertility in farm animals in tropical countries. Heat and nutritional stresses affect the reproductive performance by decreasing the expression of estrous behavior, altering ovarian follicular development and hormonal profiles, compromising oocyte competence, and inhibiting embryonic development in livestock. Climate is changed by greenhouse gases that released into atmosphere through man-made activities. Livestock contribute 18% of the production of greenhouse gases itself and causes climate change including heat stress, which has direct and indirect impact on fertility of the animals as well as reduce milk production. Adaptation to climate change and lowering its negative effect by alteration of animal micro-environment using different essential technologies are the main mitigation strategies to recover heat stress damage in this respect.

Livestock Sector

Purpose This paper aims to investigate and review adaptation measures in the livestock sector from 21 African countries through literature survey and grounded theory approaches. The adaptation themes that emerged captured essence of measures and experience drawn from varied country submissions and contexts instituted to make the livestock sector climate compatible in as far as adaptation is concerned. Design/methodology/approach Literature survey approach was used on the impacts of climate change on livestock and a review of the submitted adaptation measures. The study used grounded theory approach to derive meaning from the retrieved information. The grounded theory was derived inductively through systematic collection and analysis of data pertaining to the submitted National Communications reports. The retrieved themes were then examined and interpreted to give meaning and draw conclusions through coding, conceptualizing, categorizing and theorizing. Findings Results identify eight adaptation themes: carrying capacity and policies; integrated pasture management; capacity building, extension, training, awareness and information sharing; livestock breeding, diversification and intensification; disease, vectors and parasites management; technology, innovation, research and development; alternative livelihood; and water supply. The findings show that African Governments have been implementing effective adaptation measures for food security through building a climate resilient livestock production system. Originality/value This study is one of the first to lead to recommendations that decision- and policymakers, private sectors, relevant stakeholders and government officials and scientists should play a key role in ensuring that adaptation measures reach farmers, herders at grassroots level. In addition, governments should create an enabling environment (policies) in climate change adaptation to improve food security. These recommendations might be helpful in many communities where adaptation to climate change is a pressing issue.

Individual Vulnerability

Purpose – This paper aims at understanding how smallholder farmers are adapting to drought and what shapes their vulnerabilities and ability to adapt. Considering that their capacity to adapt to climate change has been undermined not only by the natural vulnerabilities due to their geographic location but also by the social context, gender and institution that interact to influence and determine household and individual vulnerability and responses to drought. Design/methodology/approach – Both primary and secondary data were used. Primary data were collected by use of structured questionnaires from 128 male-headed households and 122 female-headed households in eight villages in the Nguru Local Government Area, as well as from key informant interviews and focus group discussions. Findings – Climate change is not a concept recognized by most farmers and does not have standard translation in the local language; farmers believe the term refers to change in weather. Drought and crop failure are causing despair and frustration, and farmers reported that they are struggling to adapt. The resources and support inputs required for responding to climate change and variability are socially differentiated by gender, women’s and men’s responses to drought impacts as well as their access to adaptation resources and support differ significantly. Women are in particular unable to access the favored adaptation strategies promoted by Yobe State Agricultural Development Programme as a government support institution assigned with the responsibility of helping farm households adapt to climate change in ways that will increase their adaptive capacity. Originality/value – These findings are essential for informing policy decisions by ensuring that the experiences of both women and men and the context in which they operate are embedded into policy design.

Biogas Technology

Small-scale anaerobic digesters, known as biogas plants, were applied as an optimal livestock waste treatment as well as biogas supply for cooking and lighting demand for small-scale farmers in Vietnam. Although the biogas technology was introduced for nearly 30 years, the number of the constructed biogas plants is still limited. The current development of biogas plants is far below the real demand on livestock waste treatment that has increased significantly. This paper gives a comprehensive overview on the biogas plant development in Vietnam and attempts to address the challenges and discuss appropriate solutions for the further biogas development.

Agricultural Adaptation

One of the burning issues of the world is climate change. The objective of this paper is to review the issues of agricultural adaptation to climate change in the context of developing countries. Literature review type methodology is used here. Total 54 numbers of secondary materials comprising journal articles, books, working papers and documents are used for this research. It is found that Climate Change is real but highly uncertain. It poses threat to agricultural sector of developing countries and adaptation would be a possible solution. Apart from the perception of farmers other factors like the farm family characteristics (e.g. farmers’ education level, farm size, and farm’s financial health) and government support (e.g. access to extension, credit and climate information) could be the potential factors to influence adaptation. There could also be several barriers to adaptation from farmers’ perspective in the face of climate change. Lack of awareness, access to credit, information, knowledge and education to evaluate and implement new methods are the major constraint on adaptation. The appropriate science, actions and policy is required to improve the capacity and to facilitate adaptation in developing countries. JEL Classification Code: Q02; Q18
