PBL Netherlands Environmental Assessment Agency has conducted a study into the potential impact of certified sustainable production on natural capital and the related ecosystem goods and services. Forests are a well-known example of natural capital; they are valuable to society, among other things because they store large amounts of carbon. The performed cost-benefit analyses show that certified resource production has several societal benefits, such as reductions in environmental pollution, soil erosion and health damage. However, for resource producers, the financial returns of more sustainable production methods are often limited. The uneven distribution of costs and benefits over public and private actors forms a barrier to any further scale up of sustainable production. Thus, there is a need for additional solutions, besides certifying trade to help conserve ecosystems elsewhere in the world.

In dit rapport worden de mogelijkheden verkend om een duurzaam gebruik van natuurlijke hulpbronnen door economische prikkels te stimuleren. Het onderzoek betreft de economische prikkels en externe effecten in de melkveehouderij in het Groene Hart en de akkerbouw in Flevoland. Over het algemeen zal een lastenverzwaring in het gebruik van bijvoorbeeld kunstmest en gewasbeschermings-middelen relatief weinig effect hebben. Daarentegen zal het belasten van hoge emissies en het belonen van lage emissies naar verwachting meer stimuleren om negatieve externe effecten te verminderen.

Water and resource availability in sufficient quantity and quality for anthropogenic needs represents one of the main challenges in the coming decades. To prepare for upcoming challenges such as increased urbanization and climate change related consequences, innovative and improved resource management concepts are indispensable. In recent years we have developed and applied the Urban Harvest Approach (UHA). The UHA proposes to model and quantify the urban water cycle on different temporal and spatial scales. This approach allowed us to quantify the impact of the implementation of water saving measures and new water treatment concepts in cities. In this paper we will introduce the UHA and present for urban water cycles. Furthermore, we will show first results for an extension to energy cycles and highlight future research items (e.g., nutrients, water-energy-nexus).

The conservation and sustainable use of biodiversity are issues that have been high on the policy agenda since the first Earth Summit in Rio in 1992. As part of efforts to implement in situ conservation, a methodology referred to as community biodiversity management (CBM) has been developed by those engaged in this arena. CBM contributes to the empowerment of farming communities to manage their biological resources and make informed decisions on the conservation and use of agrobiodiversity. This book is the first to set out a clear overview of CBM as a methodology for meeting socio-environmental changes. CBM is shown to be a key strategy that promotes community resilience, and contributes to the conservation of plant genetic resources. The authors present the underlying concepts and theories of CBM as well as its methodology and practices, and introduce case studies primarily from Brazil, Ethiopia, France, India, and Nepal. Contributors include farmers, leaders of farmers’ organizations, professionals from conservation and development organizations, students and scientists.

Phosphate is essential for agricultural production and therefore plays a key role in the global production of food and biofuels. There are no agricultural alternatives for phosphate, and a substantial fraction of our annual phosphate consumption is dispersed into the environment where it is largely lost to agriculture. Phosphate is an irreplaceable, and to a considerable extent non-renewable, resource that is being exploited at an ever increasing rate. The ongoing depletion of phosphate resources combined with recently increased phosphate prices urge us to reconsider our phosphate consumption patterns. In addition to economic and geo-political reasons, further reducing phosphate consumption would moreover be beneficial to the quality of our environment. Even if we increase the reserve base, for which there are plenty of opportunities, it is clear that the phosphate industry will sooner or later have to make a switch from a reserve-based industry to a recycling industry.

In agroproduction systems recycling of phosphorus should be the general principle. This holds for manure, crop residues and other organic rest products. Especially the cattle feedlot industry can be a market for DGGS, being a co-product of the distillery industries. Recovery from seawater is a possible alternative for the re-use of phosphorus. These and other aspects are reviewed in this inventory on a world scale

Smallholder farming systems in Sub-Saharan Africa are often nutrient-limited systems that depend largely on the use of land resources for their subsistence. Crop-livestock integration is an effective means by which nutrients can be rapidly recycled within and between farms. However, there is great uncertainty over which are the critical stages of nutrient transfer through crop-livestock systems. Each transfer of nutrients within the farming system provides a risk of inefficiency, which depends on the type of system, its management practices and site conditions. Because livestock fulfil several functions in crop-livestock systems, and farmers manage their animals according to the weight assigned to each function, there are trade-offs between increasing animal productivity, and income from livestock and sustaining crop production through cycling nutrients from animal manure. This thesis is a contribution to development of an analytical tool, the NUANCES framework, to support the analysis of trade-offs in crop-livestock sys¬tems, with focus on opportunities for intensification and maximisation of the benefits from crop-livestock integration for smallholder farmers. The framework that was developed can be used to analyse options for intensification at different scales, from the cattle sub-system, farm scale to village scale.

Efficient use of animal manures depends on improving manure handling and storage, and on synchrony of mineralisation with crop uptake. Model calculations with the HEAPSIM model show that manure management during collection and storage has a large effect on the efficiency of C and nutrient retention. Differences in nitrogen cycling efficiency (NCE) between farms of different wealth classes arise due to differ¬ences in resource endowment. Measures to improve manure handling and storage are generally easier to design and implement than measures to improve crop recovery of N. Covering manure heaps with a polythene film reduce mass and N losses considera¬bly. For the poor to increase overall NCE, investment in cattle housing and recycling of urinary-N is required. Direct application of plant materials to soil results in more efficient cycling of N, with lower losses than from materials fed to livestock and the applying manure to the soil. However, livestock provide many other benefits highly valued by farmers.

Evaluation of lifetime productivity is a sensible strategy to target interventions to improve productivity of smallholder dairy systems. Model simulations with LIVSIM show that it is possible to maximise lifetime productivity by supplementing with con¬centrates to meet the nutritive requirements of cattle not only during lactation but also during early development to extend productive lifetime. Reducing mortality by implementing health care management programmes must be included in interventions to increase dairy outputs. Improving lifetime productivity has a larger impact on small¬holders’ income than interventions targeted to improving daily milk yields through feeding strategies.

Indicators of network analysis (NA) are useful to support discussions on diversified and sustainable agro-ecosystems and allow assessment of the effects of farm management strategies to improve the system design. The amounts of N cycled in crop-livestock systems in the highlands of East and southern Africa were small and comparable in size at all sites (less than 2.5 kg N per capita per year). Dependency on external in¬puts to sustain current production was larger for poor than for wealthier households, who had larger soil N storages per capita. Because increases in size of the network of N flows and organisation of the flows lead to increases in productivity and food self-sufficiency, combination of both strategies may improve not only productivity but also adaptability and reliability of smallholder crop-livestock systems.

An analysis of village scale interactions in a crop-livestock system of NE Zimbabwe using NUANCES-FARMSIM showed that the grasslands contribute to c. 75% of the annual feed intake of the herd of the village, and that the crop residues produced by the non-livestock owners sustained c. 30% of the intake of livestock during the critical dry season. The removal of carbon (0.3−0.4 t C y−1) resulted in a long term reduction of the yields of their farms. Impeding the access of livestock to the crop residues of non-livestock owners increases the quality of their soils modestly and improved yields in the mid- to long term. Adding mineral fertiliser to the whole (community) system con¬currently with changes to the current management of the crop residues and manures appears to be a promising strategy to boost the productivity of the community as a whole. There are benefits in terms of productivity and resource use efficiency of closer integration between crops and livestock. Opportunities seem to be small, but still may play an important role in rehabilitating soils together with other measures. However opportunities for intensification have to be explored in a broader context, taking into account that farmers face constraints at higher scales, constraints that need to be re¬laxed by proper policies and interventions.

This book text presents methodologies and case studies that provide recommendations for the conservation and use of crop wild relatives. In a national, regional or global context, the status of crop wild relatives, that are closely related to crop plants, is examined. Conservation of crop wild relatives is important to enable these species to be included in plant breeding activities for beneficial traits such as pest or disease resistance and yield improvement.

A scenario study from 2000 to 2050 has been performed (by Natuur en Milieuplanbureau, UNEP and WCMC) to explore the effects of future economic, demographic and technical developments on environmental pressures and global biodiversity. Policy options that affect global biodiversity were analysed on their contribution to the 2010 biodiversity targets agreed upon under the Convention on Biological Diversity (CBD). The mean species abundance of natural occurring species was used as indicator for biodiversity. To analyse the economic and environmental consequences of changes in global drivers and policies, we developed a global economic-biophysical framework by combining the extended GTAP model (Van Meijl et al., 2005) with the IMAGE model (Alcamo et al., 1998; IMAGE Team, 2001).

The genetic diversity comprised in farm animal species and breeds is an important resource in livestock systems. For several reasons, within the different species used for food production, only a few breeds are developed towards high-output breeds fitting in high-input systems. In this process many breeds are set aside from the food producing livestock systems. These breeds will be faced with extinction unless new functions for these breeds are found. This is a real threat for the genetic diversity within species. This book is intended to give insight into the issues of the utilisation and conservation of farm animal genetic resources towards a broad group of readers interested in these subjects. The insight is presented as applications of population, molecular and quantitative genetics that can be used to take appropriate decisions in utilisation and conservation programmes. The first two chapters discuss the decisions to be made in utilisation and conservation. Chapter 3 surveys the different ways in which the diversity we observe within a species can be characterised. Chapter 4 illustrates recent results using this theory for utilisation and conservation purposes. Chapters 5, 6 and 7 give theoretical backgrounds necessary to make decisions and chapters 8 and 9 present the operation and practical implications of selection and conservation schemes

This paper investigates environmental and design related issues that can affect the performance of small-scale water harvesting schemes in theTigray region of northern Ethiopia. Results indicate that the impact of evaporation loss during the rainy season on net harvested water is generally small, and depends on the extent of the surface area of the ponds. However, the impact of the seepage loss on the net harvested water is very high unless there is proper lining of the bed and walls of the ponds. The irrigated area can be increased considerably if proper water saving and utilization measures and mechanisms are implemented. The current silt trap structures are ineffective in minimizing the sediment deposition in the ponds. The design, construction and maintenance of the structures need to be improved in order to reduce the sediment deposition and increase the water storage capacity of the ponds. As there is little experience with the extensive use of ponds and hand dug wells for supplementary irrigation in Tigray, the soils of almost all schemes are currently salt free. If the soil salinity and good quality water of the ponds are taken into account, salinity may not be a threat for farmers using ponds for supplementary irrigation. However, the water quality of wells is poor. Besides, since they are continuously recharged by the groundwater, most of the wells irrigate longer period than the ponds. Farmers using wells would have to implement necessary measures indicated earlier to minimize the effect of salinity.

In Kenya, conservation and sustainable utilization of the environment and natural resources form an integral part of national planning and poverty reduction efforts. However, weak environmental management practices are a major impediment to agricultural productivity growth. This study was motivated by the paucity of literature on the poverty-environment nexus in Kenya, since poverty, agricultural stagnation and environmental degradation are issues of policy interest in the country¿s development strategy. The paper builds on the few existing studies from Kenya and explores the impact of household, farm and village characteristics as well as the development domain dimensions on household welfare and investment in soil and water conservation. The results show that strengthening the tenure security improves household welfare. Further, soil quality, topography and investments in soil and water conservation affect household welfare. Agroecological potential, which is related to environmental conservation, is also a key correlate of poverty. Results for investment in water and soil conservation confirm the importance of tenure security in determining adoption and also the intensity of SWC investments. We also find that household assets, farm characteristics, presence of village institutions and development domain dimensions are important determinants of adoption and intensity of soil and water conservation investments. The results for both poverty and investment in soil and water conservation suggest the existence of a strong poverty-environment link in our sample. The results also suggest that rural poverty can be alleviated by policies that improve environmental conservation and strengthen land tenure security. The study also underscores the importance of village institutions in both investment adoption of soil and water conservation and in improving household welfare.
