Livestock development and climate change in Turkana District, Kenya
The main purpose of the study presented here is to shed some light using simple and aggregated methods on the following question: In view of the expected climate change, is there also a long-term perspective for livestock development in the area, i.e. will the Turkana ecosystem be able to sustain livestock production during the next few decades? In our search for an answer to this question, we looked at the current pressure on the environment, tried to interpolate the predicted climate change to the Turkana District scale and started exploring some of the possible impacts of climate change on the environment and the people depending on it. Due to the simplistic nature of the analyses performed, we consider these figures to be indicative only. This study goes hand in hand with another one focussing on market access and opportunities
The livestock-climate-poverty nexus: A discussion paper on ILRI research in relation to climate change
Climate change will have severe impacts in many parts of the tropics and subtropics. Despite the importance of livestock to poor people and the magnitude of the changes that are likely to befall livestock systems, the intersection of climate change and livestock is a relatively neglected research area. Little is known about the interactions of climate and increasing climate variability with other drivers of change in livestock systems and in broader development trends. Evidence is being assembled that the temporal and spatial heterogeneity of household responses may be very large. While opportunities may exist for some households to take advantage of more conducive rangeland and cropping conditions, for example, the changes projected will pose very serious problems for many other households. Furthermore, ruminant livestock themselves have important impacts on climate, through the emission of methane and through the land-use change that may be brought about by livestock keepers. Given that climate change is now being seen as a key development challenge, and that a very large global community is already working on climate-change-related issues, the CGIAR in general, and ILRI in particular, need to consider carefully how the research agenda might be adjusted to respond. While the global environmental change community is very large, ILRI as a small institute can still contribute effectively to the climate change / development debate by focusing on a few key niches, through alliances with carefully chosen collaborators. This discussion paper is an attempt to assemble and summarise relevant information concerning climate change, livestock and development, and to identify what these key niches might be. The report briefly summarises what is known about climate change and its effects on agroecosystems, and summarises the current limits to prediction. It reviews the literature on climate change impacts on livestock and livestock impacts on climate, and thus sets out to answer the question, what do we know? Knowledge and data gaps are then identified, and a synthesis presented in relation to our clients and stakeholders and to alternative providers of knowledge and information. The paper ends by looking at the questions, what do we not know, and what should we do about it, with a discussion of recommendations for ILRI activities in the area, and the strategic alliances needed, some of which already exist
Climate change: do we know how it will affect smallholder livestock farmers?
What is known about the likely impacts of climate change on resource-poor livestock keepers in the developing world? Relatively little, and the International Livestock Research Institute (ILRI) and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) are working to improve this knowledge. This Brief outlines how a group of scientists at ILRI reviewed some elements of the complex relationship between livestock and climate change in developing countries with a forward-looking approach. The objective was to help set research priorities: to inform the debate as to what research for development organizations such as ILRI could and should be doing in the area of climate change work that could add value to the large amounts of work already being carried out by the Global Change community on cropping systems and natural resources management. Originally designed to guide ILRI’s research on climate change, this work has had a broader impact by informing the investment strategies of several other research-for-development organizations, including donors
Exploring opportunities around climate-smart breeding for future food and nutrition security
There is a 95% chance that warming will exceed 2°C by the end of the century (Raftery et al. 2017). Global crop productivity is projected to fall by 5-10 % per degree of warming (Challinor et al. 2014), with even greater losses likely for some crops in some areas. The challenge of meeting future food demand is increasing, and climate change is already diminishing our ability to adapt through crop breeding (Challinor et al. 2016; Aggarwal et al. 2019). Recent research is suggesting that increases in climate variability are already affecting the number of food-insecure people, and that increasing atmospheric CO2 concentrations may affect the nutrient content of some food staples, with serious implications for food and nutrition security (Smith and Myers 2018).
New crop varieties will be needed that can deliver higher yields as well as possessing the ability to withstand heat and greater tolerances for the secondary effects of a warmer world, such as increased pressures from drought, water-logging, pests and diseases, and reduced nutritional quality due to higher levels of CO2. The systems for accelerated delivery of climate-resilient varieties into food producers’ hands need to be massively upgraded (Cramer 2018). Innovative holistic breeding strategies for multiple traits will be needed that embrace the full pipeline from trait discovery to varietal deployment and seed system development
Entrances and exits: changing perceptions of primary teaching as a career for men
Original article can be found at: http://www.informaworld.com/smpp/title~content=t713640830~db=all Copyright Informa / Taylor and Francis. DOI: 10.1080/03004430802352087The number of men in teaching has always been small, particularly in early childhood, but those that do come into teaching usually do so for the same reasons as women, namely enjoyment of working with children, of wanting to teach and wanting to make a difference to children's lives. However, in two separate studies, the authors have shown that on beginning teacher training in 1998, and at the point of leaving the profession in 2005, men and women tend to emphasise different concerns. This article will explore those differences and seek possible explanations for how men's views of teaching might be changing over time.Peer reviewe
Mapping hotspots of climate change and food insecurity in the global tropics
This study was coordinated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) to identify areas that are food insecure and vulnerable to the impacts of future climate change, across the priority regions for the CGIAR centres. The research was undertaken by a team of scientists from the International Livestock Research Institute (ILRI). The study relied on maps: first, of variables that indicate the different aspects of food security (availability, access and utilization), and second, of thresholds of climate change exposure important for agricultural systems. Vulnerability was assessed using a domain approach based upon
the Intergovernmental Panel on Climate Change (IPCC) framework of vulnerability as a function of exposure, sensitivity and coping capacity. Nine domains were identified; for each domain, areas of the tropics were classified by high or low exposure, high or low sensitivity, and high or low coping capacity
Classifying livestock production systems for targeting agricultural research and development in a rapidly changing world
A myriad of agricultural and livestock production systems co-exist in the developing countries. Agricultural research for development should therefore aim at delivering strategies that are well targeted to the heterogeneous landscapes and diverse biophysical and socioeconomic contexts the agricultural production system is operating in. To that end, in the recent past several approaches to spatially delineate landscapes with broadly similar production strategies, constraints and investment opportunities, have been applied. The mapped Seré and
Steinfeld livestock production classification, for example, has been widely used for the targeting of pro-poor livestock intervention within ILRI. In this paper we describe potential methodologies for the inclusion of crop-specificity and intensification in the existing Seré and
Steinfeld livestock systems classification. We also present some first broad-brush future
projections of these detailed crop-livestock production systems. A number of example applications are discussed and recommendations for future improvement and use are made.
While the production system classifications are especially useful for bio-physical applications such as livestock-environment interactions and feed assessments, the links with socioeconomic factors still need to be explored further. Also, it is only one of the necessary building blocks for better targeting of research and development efforts. We, however,believe that the proposed system classifications will be of use to a variety of agricultural and livestock scientists and development agents alike. In addition, they serve as practical
examples making the case for the use of spatial stratification when targeting agricultural research and development
