CATTLE AS ASSETS: ASSESSMENT OF NON-MARKET BENEFITS FROM CATTLE IN SMALLHOLDER KENYAN CROP-LIVESTOCK SYSTEMS

This paper uses data from a survey of two hundred and fifty cattle households in three cattle keeping systems; intensive, semi-intensive and extensive systems to estimate the value of non-market, socio-economic benefits of cattle in Kenya. These benefits of cattle keeping are of special importance in developing countries, where financial markets function poorly and opportunities for risk management through formal insurance generally absent. However, when estimating the total contribution of livestock, these non-market functions are often ignored since they are difficult to value, yet they may contribute to a better understanding of livestock production systems. The use of contingent valuation method is employed in this study to elicit these non-market values. Econometric estimations are then used to assess the factors influencing the non-market benefits function. The results indicate that these benefits are highly valued by cattle keepers and comprise approximately 20% of the animal's total value across the three systems. They are influenced by various production system and household related factors. Implications for policy are drawn.Livestock Production/Industries, QQ112, QQ118, DD223,

A conceptual model and analytical framework for studying purchasing & supply management within SMEs

Abstract: The central objective of this conceptual paper is to gain a better understanding under what circumstances purchasing and supply activities within Small & Medium-sized Enterprises (SMEs) are managed. Purchasing & Supply Management (PS Management) within SMEs differs from that in large enterprises. SMEs have different organisational settings and are not small versions of large enterprises. Whilst there is abundant literature on SMEs as well as on PSM, there is only little literature on PSM within SMEs. PSM research within SMEs must consider specific characteristics such as informal organisation, less specialization in business functions and less available resources. SME management will focus more on the overall operations and less on specific business functions. The approach of SME management to inward-bound purchasing and supply activities is often holistic; its approach to outward-bound purchasing and supply activities is characterized by a relative dependent position in supply chains. This paper proposes a conceptual model to explain the relationship between the governance of purchasing and supply activities and their purchasing and supply performance. The paper adopted the Transaction Cost Theory (TCT) with levels of integration to describe five governance types. To explain the relation between these governance types and performance, the paper includes the TCT-related moderating variables general uncertainty (macro and meso environment) and asset specificity (meso environment). It also introduces the moderating variables SME characteristics and management characteristics and business model. From this conceptual model the paper then develops an analytical framework which describes the five governance types and the circumstances under which they are ideal-typically sustained. The conceptual model and analytical framework combine different domains of literature to enhance the understanding of the different forms of purchasing and supply activities within an SME context. Combining these different domains gives beneficial insights that cannot be found in the separate literature domains. The applying model and framework in empirical research will enable the design of management instruments. Hence this paper is a starting point into purchasing and supply management research within SMEs aimed at supporting SMEs in their performance

Types, levels and causes of post-harvest milk and dairy losses in sub-Saharan Africa and the Near East: Phase one synthesis report

The following report synthesizes and highlights the types, causes and levels of postharvest milk and dairy product losses in Ethiopia, Kenya, Syria, Tanzania and Uganda, based on national study documents submitted by consultants from the respective countries. The dairy industry strengths, weaknesses, opportunities and threats in each country are also discussed. Based on these, recommendations on the next steps have been suggested

How motifs condition critical thresholds for tipping cascades in complex networks: Linking Micro- to Macro-scales

In this study, we investigate how specific micro interaction structures (motifs) affect the occurrence of tipping cascades on networks of stylized tipping elements. We compare the properties of cascades in Erd\"os-R\'enyi networks and an exemplary moisture recycling network of the Amazon rainforest. Within these networks, decisive small-scale motifs are the feed forward loop, the secondary feed forward loop, the zero loop and the neighboring loop. Of all motifs, the feed forward loop motif stands out in tipping cascades since it decreases the critical coupling strength necessary to initiate a cascade more than the other motifs. We find that for this motif, the reduction of critical coupling strength is 11% less than the critical coupling of a pair of tipping elements. For highly connected networks, our analysis reveals that coupled feed forward loops coincide with a strong 90% decrease of the critical coupling strength. For the highly clustered moisture recycling network in the Amazon, we observe regions of very high motif occurrence for each of the four investigated motifs suggesting that these regions are more vulnerable. The occurrence of motifs is found to be one order of magnitude higher than in a random Erd\"os-R\'enyi network. This emphasizes the importance of local interaction structures for the emergence of global cascades and the stability of the network as a whole

How entrepreneurial New Zealand firms procure environmental technical innovations for the construction industry

Construction industries in New Zealand and abroad have a low track record for successful sustainable innovations. This often has a negative impact on private and government spending, and on quality, society and the environment. This paper posits that the construction industry needs step-change (i.e. architectural, system, radical, modular) environmental technical innovations to make drastic improvements. Often entrepreneurial or small to medium-sized firms at the beginning of supply chains or from other industries will introduce such innovations. These firms will use the innovation capacity of suppliers and of their own organisations to transform and commercialise such innovations into the industry. However, after an extensive literature review it remains unclear how innovative New Zealand firms procure environmental step-change technical innovations for the construction industry. The research focuses on procurement activities within such firms who supply the New Zealand construction industry. These procurement activities interact with (internal and external) innovation activities for an optimal firm performance (in economic and environmental terms) and are affected by clusters of internal and external variables. The heart of the research consists of two rounds of case studies alternating with two rounds of collaborative focus studies. The research focus is on New Zealand although part of this study will be replicated in the Netherlands. It is part of a doctoral project

Traditional milk market in Assam: Potential for income and employment generation

The integrated food supply chains have emerged as the fastest growing and widely visible market phenomenon. Yet in most developing countries, small scale milk market agents and chains supplying fresh milk and traditionally processing dairy products play a major role. They are the key outlets for small holder dairy producers and are the main source of fresh milk supply for consumers. These traditional small-scale markets account for over 80 per cent of the marketed milk in many countries in South Asia, sub-Saharan Africa and Latin America (Omore et al., 2004). In India too, more than 80 per cent of milk marketed still passes through these traditional milk marketing channels (Steven et al., 2008). The much hyped co-operative dairy development in India has also not been able to significantly affect the dominance of these traditional milk marketing channels. But, the functioning of the traditional milk market and its potential in income and employment generation has not been conceived properly in India. The understanding of the traditional milk marketing and processing chains are helpful in evolving policies and developmental strategies for creating an efficient milk marketing system. A study was planned in one of the backward states of India, namely Assam. In this state, 97 per cent of milk marketing is controlled by traditional milk market agents. (Kumar et al., 2007; Sirohi et al., 2009). The organised marketing and processing of milk in Assam remains insignificant. Formal milk pasteurisation and dairy product processing channels, both under co-operative and private sectors, account for hardly 3 per cent of the total locally marketed milk. The smallholder producers in the state have poor market access. The lack of alternative market options forces them to sell in the traditional market. In this backdrop, this study was undertaken with the objectives of (i) examining the costs and returns in traditional milk marketing and processing, (ii) estimating the milk producer's share in consumer rupee and marketing margins of different actors in the marketing chain, (iii) assessing the potential of traditional milk market in employment generation, and (iv) identifying the factors for scaling up the volume of business of the informal milk market agents in the state. The paper is organised as follows. Section II presents the data and methodology used in the study. The economics of traditional milk marketing and processing are discussed in Section III. Section IV deliberates on the potential of employment generation in the traditional milk market, while important determinants of the volume of milk handled by the traditional milk market agents have been discussed in Section V. The last section draws the conclusion and policy implications of the study

Dairy development for the resource poor. Part 3: Pakistan and India dairy development case studies

The process of dairy development that this study addresses is driven by underlying fundamental changes in economic growth, the value of resources and consumer demand. However, it is also shaped by public policies, interventions and investment decisions and will be accompanied by changes in impact on incomes, opportunities and livelihoods of producers and changes in opportunities and returns for market agents and investors. This study examines dairy development in two key dairy producing regions in the developing world: East Africa and South Asia. The aim of the study is to analyse the trends in dairy development in these two regions and identify their key determinants, to analyse the impact of policy interventions on those trends and to identify impacts of dairy development, particularly on the poor. The study is reported in three parts: Part 1 presents a conceptual framework for dairy development, followed by a section presenting a regional analysis of dairy development trends across all the countries in the two regions and a synthesis of the outcomes of the case study analyses (see below), highlighting implications for policy interventions and investment, including proposing a model for pro-poor dairy development. Parts 2 and 3 consist of in-depth case studies and analyses of dairy development trends, determinants and outcomes in Kenya and Ethiopia (Part 2) and India and Pakistan (Part 3 – this report)
