The paper discusses the contribution of crop residues (CR) to feed resources in the context of the water productivity of CR in livestock feeding, using India as an example. It is argued that crop residues are already the single most important feed resource in many livestock production systems in developing countries and that increasing their contribution to livestock feeding needs to be linked to improving their fodder quality. Using examples from multi-dimensional crop improvement, it is shown that CR fodder quality of key crops such as sorghum, rice and groundnut can be improved by genetic enhancement without detriment to grain and pod yields. Improving crop residue quality through genetic enhancement, agronomic and management interventions and strategic supplementation could improve water productivity of farms and systems considerably. The draw-backs of CR based feeding regimes are also pointed out, namely that they result in only moderate levels of livestock productivity and produce higher greenhouse gas emissions than are observed under feeding regimes that are based on high quality forages and concentrates. It is argued that feed metabolisable energy (ME) content should be used as an important determinant of livestock productivity; water requirement for feed and fodder production should be related to a unit of feed ME rather than feed bulk. The paper also revisits data from the International Water Management Institute (IWMI) work on livestock–water productivity in the Indian state of Gujarat, showing that water input per unit ME can vary several-fold in the same feed depending on where the feed is produced. Thus, the production of one mega joule of ME from alfalfa required 12.9 L of irrigation-derived water in south Gujarat but 50.7 L of irrigation-derived water in north Gujarat. Wheat straw in south Gujarat required 20.9 L of irrigation-derived water for 1 MJ ME and was in this instance less water use efficient than alfalfa. We conclude that water use efficiency across feed and fodder classes (for example crop residue v. planted forages) and within a feed is highly variable. Feeding recommendations should be made according to specific water use requirement per unit ME in a defined production system.

This atlas provides information on the salient findings of the project entitled "Ensuring Health and Food Safety from Rapidly Expanding Wastewater Irrigation in South Asia" coordinated by the International Water Management Institute (Hyderabad office). The three year project funded by the German Federal Ministry of Economic Cooperation and Development (Bundesministerium für Wirtschaftliche Zusammenarbeit und Entwicklung - BMZ) was carried out in two countries, India and Pakistan, in collaboration with a number of international and local partners. This atlas highlights the findings from India. The atlas comprises thematic maps and their corresponding descriptions highlighting the key findings of the project. The wastewater use in agriculture described here is associated with a polluted riverine system, due to all types of city discharges. As such, it can be expected that the water quality can change considerably in different stretches of the 40 km stretch of the river, with the head end being more polluted than the tail end. Therefore in order to avoid a rigid classification, the descriptions to the maps refer to the term "(Musi) river water". In the rest of text, the term "wastewater" is used in the context of the chemical and biological attributes associated with agronomic and health risks in any given stretch of the river. The atlas was prepared as a summary document of the key findings of the project, to promote a discussion on the wastewater use in agriculture, at the dissemination workshop held in October 2008.

In 2006 a comprehensive sampling program was undertaken in two pre-selected peri-urban villages in Faisalabad, Pakistan to evaluate the soil and agronomic impacts of long-term (25–30 years) untreated wastewater re-use on wheat grain and straw yields and attributes of wheat straw fodder quality. Soil SAR, ESP, RSC and ECe were 63%, 37%, 31%, and 50% higher under wastewater (WW) as compared with canal water (CW) irrigated plots. Further, 2.7 and 6.65 fold increases in soil NO3- + NO2 - - N and Olsen-P were observed in WW as compared with CW irrigated plots. However, no significant differences in grain yield, wheat straw biomass, or fodder quality attributes were observed between WW and CW irrigated plots. In addition, for both CW and WW irrigated plots wheat straw, Cd and Pb concentrations were orders of magnitude below the EC Maximum permissible levels for Pb and Cd in feed materials and thus pose no threat to the fodderlivestock food chain. Further, elevated soil N associated with WW irrigated plots has a significant (p<0.01) positive influence on fodder quality by increasing the N content. Factorial ANOVA with covariance indicates that effective management of the elevated soil ECe in WW irrigated plots would increase grain yield and wheat straw biomass by 853 kg ha-1 (19.5%) and 819 kg ha-1 (18.6%) respectively as compared with CW irrigated plots. In Faisalabad, if managed appropriately to address emerging salinity issues the contribution of wastewater irrigation to the achievement of MDGs 1 and 7 could be significant if adverse impacts remain as marginal as found in this study.

This project aims to identify the risks and benefits associated with the use of wastewater in urban and peri-urban fodder and vegetable cropping systems in India and Pakistan, where wastewater is largely untreated due to lack of public finance. Two mega-cities (Faisalabad, Pakistan and Hyderabad, India, with large untreated wastewater irrigation areas have been selected a) for comparative purposes and b) to develop and promote country-specific risk mitigation options. With a particular focus on food safety, livelihoods and livestock, the research will combine field and laboratory methods and structured interactions with producers, consumers, and authorities (urban planning, public health and water management). The goal of the project is to improve health and safeguard wastewater-dependent livelihoods of resource-poor urban and peri-urban farmers and consumers in developing countries. This overlaps with IWMI’s mission to improve water and land resources management for food, livelihoods and nature. The project’s purpose is to develop and promote the uptake of a set of risk mitigation options based on a comprehensive assessment of risks and benefits associated with wastewater irrigation in Hyderabad (India) and Faisalabad (Pakistan). The project will enable the uptake of the recommendations in two countries with large wastewater-irrigated areas and different political - institutional environments.

The concept of water productivity (WP) or ‘more crop per drop’ has been revived recently in international water debates. Its application has notably been extended from single crops to mixed farming systems, integrating both crops and livestock, with the wider objective of reducing poverty. Using evidence from the Ganga Basin, India, we discuss the relevance of this concept as a tool to guide interventions for livelihood improvement and poverty alleviation. We argue that WP studies would benefit from greater attention to the role of capitals, inequities and institutions. Firstly, it is crucial to acknowledge the heterogeneity of capitals and capabilities of farmers to make changes in their farming systems and practices and avoid one-fix-all interventions. Identifying pre-existing inequities in water access within and among communities will support better targeting of poor communities. WP interventions can either reinforce or reduce inter-household inequities within communities. We stress the need for assessment of institutional impacts of WP interventions on water access and development.

Projections suggest that annual per capita water availability in the Indo-Ganga Basin (IGB) will reduce to a level typical for water-stressed areas. Producing more crop and livestock products, per unit of agricultural water invested, is advocated as a key strategy for future food production and environmental security in the basin. The objective of this study was to understand the spatio-temporal dynamics of water requirements for livestock feed production, attendant livestock water productivity (LWP) and implications for the future sustainable use of water resources. We focused on three districts in the IGB representing intensive (higher external inputs, e.g. fertilizer, water) and semi-intensive (limited external input) crop-livestock systems. LWP is estimated based on principles of water accounting and is defined as the ratio of livestock beneficial outputs and services to the water depleted and degraded in producing these. In calculating LWP and crop water productivity (CWP), livestock, land use, land productivity and climatic data were required. We used secondary data sources from the study districts, field observations and discussions with key informants to generate those data sets. Our result showed that the volume of water depleted for livestock feed production varied among the study systems and was highly affected by the type of feed and the attendant agronomic factors (e.g. cropping pattern, yield). LWP value was higher for intensive systems and affected by agricultural water partitioning approaches (harvest index, metaolizable energy). LWP tended to decrease between 1992 and 2003. This can be accounted for by the shift to a feeding regime that depletes more water despite its positive impacts on animal productivity. This is a challenging trend with the advent of and advocacy for producing more agricultural products using the same or lower volume of water input and evokes a need for balanced feeding, by considering the nutritive value, costs and water productivity of feed, and better livestock management to improve LWP.

This CGIAR-CPWF Project was designed and conducted by the International Water Management Institute (IWMI), in partnership with international and national partners, to address the relative neglect of livestock water needs of crop-livestock farming systems. The primary objective of this project was to optimize the productive use of water in the crop-livestock farming systems of semi-arid areas to enhance livelihoods, reduce poverty, contribute to gender equity, and protect the environment. This was addressed through an integrated approach led by a multi-disciplinary team across three States of the Ganga Basin.

Purpose – The main purposes of this paper were to assess effects of smallholder farmers access to livelihood capital (e.g. land, livestock and water) on livestock water productivity (LWP) and to evaluate impacts of selected interventions in reducing livestock water demand (per unit of livestock product) and therefore increasing LWP. Design/methodology/approach – A total of 203 sample farm households were selected in intensive and semi-intensive crop-livestock systems of Indo-Ganga basin of India. A household survey was undertaken to capture data on land, water and livestock management. For the analysis, sample farms were clustered into poor, medium, better-off. LWP is estimated as a ratio of livestock beneficial-outputs (e.g. milk) to depleted-water (i.e. evapotranspired water to produce livestock feed). Impacts of selected interventions, on LWP, were analyzed using scenarios developed on a spread sheet model. Findings – The results showed different LWP values among farm-clusters and levels of intensification. The intensive systems showed higher LWP than the semi-intensive. In the baseline, dairy water demand to produce a liter of milk was higher than the world average: ranging between 1,000 and 29,000 L. Among the farm-clusters, variation of LWP was system specific and affected by farmers’ access to virtual water trading (i.e. milk and feed). Improving milk productivity, feed quality and feed water productivity reduced livestock water demand per liter of milk substantially and, therefore, the saved water can be used to augment ecosystem services that can mitigate the impacts of climate change. Originality/value – This paper revealed that in the study systems LWP, in the business as usual scenario, is low. But by improving animal productivity, quality feed supply and water conservation substantial volume of water can be saved.

The present study argues that there are heterogeneous farm systems within the drylands and each farmsystem is unique in terms of its livelihood asset and agricultural practice, and therefore in sustainability.Our method is based on household survey data collected from 500 farmers in Anantapur and KurnoolDistricts, in Andhra Pradesh State of India, in 2013. We carried out principal component analysis (PCA)with subsequent hierarchical clustering methods to build farm typologies. To evaluate sustainabilityacross these farm typologies, we adopted a framework consisting of economic, social and environmentalsustainability pillars and associated indicators. We normalized values of target indicators and employednormative approach to assign different weights to these indicators. Composite sustainability indices (CSI)were then estimated by means of weighted sum of indicators, aggregated and integrated into farm typolo-gies. The results suggested that there were five distinct farm typologies representing farming systemsin the study area. The majority of farms (>70%) in the study area are small and extensive (typology 1);marginal and off farm based (typology 2). About 20% of the farms are irrigation based and intensive (typol-ogy 3); small and medium and off farm based (typology 4) and irrigation based semi-intensive (typology5). There was apparent variability among farm typologies in terms of farm structure and functions andcomposite sustainability indices. Farm typologies 3 and 5 showed significantly higher performances forthe social and economic indices, while typologies 2 and 4 had relatively stronger values for environment.These discrepancies support the relevance of integrated farm typology- and CSI approaches in assessingsystem sustainability and targeting technologies. Universally, for all farm typologies, composite sustain-ability indices for economic pillar was significantly lower than the social and environment pillars. Morethan 90% of farmers were in economically less-sustainable class. The correlations between sustainabilityindices for economic and environment were typology specific. It was strong and positive when aggre-gated for the whole study systems [all samples (r = 0.183; P < 0.001)] and for agriculture dependent farmtypologies (e.g. typologies 1 and 3). This suggests the need to elevate farms economic performance andcapacitate them to invest in the environment. These results provide information for policy makers toplan farm typology–context technological interventions and also create baseline information to evaluatesustainability performance in terms of progress made over time.

Closing the yield gap and enhancing efficiency in rainfed maize production systems in Ethiopia requires urgent action in increasing the productivity of degraded agricultural land. The degradation of land through continuous compaction and decline in the organic matter has resulted in a wide-spread formation of a hardpan that restricts deep percolation, prevents plant root development, and, ultimately can lead to increased erosion. Studies exploring practical low-cost solutions to break the hardpan are limited in Ethiopia. The main objective was to evaluate soil mechanical (i.e. modified plow or Berken plow) or biological intervention (i.e. intercropping with pigeon pea) effectiveness to enhance soil water management and crop yield of rainfed maize systems whilst reducing soil erosion and runoff. Five farm fields, each including four plots with different tillage treatments, were monitored during two rainy seasons in 2016 and 2017. The treatments were: (i) farmers practice under conventional (CT) tillage; plots tilled three times using an oxen driven local plow Maresha, (ii) no-till (NT), (iii) Berken tillage (BT), plots tilled three times using an oxen pulled Berken plow, and (iv) biological (CT + Bio), taprooted pigeon pea intercropped with maize on plots conventionally tilled. Results showed that mean tillage depth was significantly deeper in the BT (28 cm) treatment compared to CT and CT + Bio (18 cm) treatments. Measured soil penetration resistance significantly decreased up to 40 cm depth under BT and maize roots reached 1.5 times deeper compared to roots measured in the CT treatment. Under BT, the estimated water storage in the root zone was estimated at 556 mm, 1.86 times higher compared to CT, 3.11 times higher compared to NT and 0.89 times higher compared to CT + Bio. The positive effects on increased water storage and root development resulted in an average increase in maize grain (i.e. 15%, 0.95 t ha- 1 ) and residual above ground biomass (0.3%, 6.4 t ha- 1 ) leading to a positive net benefit of 138 USD ha- 1 for the BT treatment compared to the CT treatment. The negative net benefit obtained under CT and CT+Bio was mainly related to the high labor cost related to plowing, weeding, planting, and fertilizer application whilst in the NT this was related to the significantly lower maize yields. The positive effects in the BT treatment, and to some extent the CT+Bio treatment show great potential for smallholder rainfed maize systems where degraded soils with hardpans and high variability in rainfall prevail.
