Cassava processing is an industry common to most West African countries as well as in other tropical countries of the world. The processing of cassava is known for its high consumption of water resources. This study therefore investigates the potential for cassava processing water conservation using combined peroxide-oxidation and adsorption recycling processing technology. A Sequential Peroxide-Oxidation and Adsorption treatment process was established by producing cassava peel carbon and activated carbon from waste cassava peels. This was used in the adsorption of pollutant parameters in oxidized cassava processing wastewater. The study further went on to estimate the volume of water that could be conserved in Nigeria through the employment of the Sequential Peroxide-Oxidation and Adsorption treatment process with the aid of a 3-scenario water-based estimation techniques. The research revealed that the estimated volume of water employed in processing cassava through fermentation process is about 1,525 l/ton while that for non-fermentation process is about 960 l/ton. However, an estimated 104,951.36, 100,195.20 and 95,639.04 million litres of water could be conserved considering each of the three cassava process combination scenarios. The study concluded that if cassava industry could make use of the combined peroxide-oxidation and adsorption recycling processing technology described as in the experimental procedure, substantial volume of water resources could be conserved and recycled for other uses such as irrigation, as well as groundwater recharge thereby improving water budget.

The 43<sup>rd</sup> Congress of the Spanish Association of Cuniculture (ASESCU) was held in Calamocha (Teruel province, Aragon region, Spain) from 30th to 31st May 2018, hosted by the Cooperative Society “Esperanza del Jiloca” (CEJI) and the City Council of Calamocha. The three main talks focused on strategies against antibiotic resistance in rabbit farming: one explaining the relevance of this problem and the responsibility of each agent to improve it, another expounding the “Spanish National Plan against Antibiotic Resistance”, and the third showing the first milestones reached in reducing antibiotic use on rabbit farms. Specific sessions were devoted to explaining the outcomes of the three research projects supported by the partnership between the Spanish Institute of Agricultural Research (INIA) and the Rabbit Meat Marketing Board (INTERCUN): one related to welfare and health of rabbit does under different housing systems, the second devoted to the prevention and control of rabbit viral diseases, and the third investigating the etiopathogeny and control of epizootic rabbit enteropathy. In addition, the role and operation of INTERCUN was highlighted. The Chair of ASESCU spoke about this association’s role in the IDCURA project, a working group focused on innovation and divulgation in reducing antibiotic use in rabbit farming. The closing speech explained the workings of LONCUN, the latest reference market for benchmark prices of rabbit meat activated in Spain. Moreover, a total of 20 communications were presented both in working sessions with oral messages and posters (nutrition, pathology, biosecurity and sustainability, housing and welfare, and reproduction and genetics). The meeting was attended by more than 210 participants from several European, American and African countries. Abstracts of the contributions presented are reported below.

The evidence does not support gloomy generalizations about an irreversible African environmental crisis or pessimistic arguments that barriers to adopting Green Revolution technologies are insuperable. Although evidence on agricultural technology in Africa is often unreliable, food output and grain yields do appear to have risen strongly in some African economies.. Huge variations in crop yields, including within similar agro-ecological zones, suggest massive potential for policies to promote a rapid increase in yields. Agricultural research and development (R&D) within African countries—and production on many large-scale farms—has shown that dramatically higher yields are possible. Crop yield improvements—with the aid of suitable high-yield varieties (HYVs), public agricultural research spending, and especially investment in irrigation—are possible without draconian resettlement schemes, without wasteful extension service spending, and without recourse to micro-finance schemes. The methods underpinning commonly produced estimates of yields are unreliable, calling into question conventional wisdom that small farms are more efficient than larger farms.

Rainwater harvesting from roof is considered as valuable water resources. Material Flow Analysis (MFA) of water in Mahasarakham University (Khamriang Campus) shows that rainwater harvesting from roof can reduce water supply production by 7% and save more than 200,000 Bt/year for water treatment cost. The sensitivity analysis suggests that by 5% water supply conservation and 20% additional rainwater harvesting, MSU could have enough water resources. The rainwater is suitable to be substituted water for gardening due to the convenience to assemble an above ground storage tank or a pond to store harvested rainwater from roof. The current practice of rainwater is collected and discharged into drainage system and treated in wastewater treatment plant. Utilisation of rainwater harvested could reduce wastewater amount that must be treated by 9%. Rainwater harvesting and reuse should be promoted in campus in order to encourage sustainable living and water conservation policy.

Seasonal streams (wadis) are of vital importance in dry and semidry countries including Sudan. Depending on the rainfall variability of the country, the annual discharge of such wadis was estimated to range from 3 to 7 km3 per annum. In the present study two wadi-discharge prediction methodologies were used to predict the discharge of Khor (wadi) Abu Fargha. The first methodology depends on the El Nino Southern Oscillation (ENSO) event which was divided into six distinct stages. The discharge during each stage was compared to previously estimated rainfall in the dry zone of the Sudan during the concurrent stage. The methodology was found to illustrate about 83% of the discharge behaviour of Khor Abu Fargha. This high prediction skill is attributed to the fact that the wadi is located in an area that is influenced by the ENSO event and to the availability of the discharge data for consecutive 34 years. The use of global sea surface temperatures (SSTs) in rainfall seasonal forecast studies was initiated during the 1990s through the development of empirical-statistical models. Using such methodology the models predicting Abu Fargha discharges were found to excel those for some meteorological stations and the dry zone of the Sudan as well. This is attributed to the fact that wadi discharges represent the whole catchment area whereas rainfall data represent only the rain gauge readings. The models using May global SSTs achieved better predictability in Abu Fargha discharges the thing which was found to be consistent with the results obtained in previous studies by Kassala meteorological station which is located in the vicinity of the wadi. The chapter illustrates the use of the wadi prediction information in forecasting the available storage of the aquifers and concluded that combining the different information, realistic management of surface and ground water resources can be achieved. The study recommended the use of water conservation techniques and integrated dryland management approaches.

Abstract A water rights trading scheme in China is currently in its initial stage of development, but is without a complete pricing mechanism. This paper proposes a pricing model for transfers of water rights from agriculture to industry in water-deficient areas of China. Both the cost price and the earnings price are considered and incorporated into the model. The cost price includes construction costs, operation and maintenance costs, renewal and reconstruction costs, and economic compensation for ecological damage. The earnings price is calculated according to a reasonable return coefficient and the difference in economic value of the water resources to the buyer and seller. The value of water resources was estimated based on emergy theory in accordance with the principle of mutual benefits equilibrium. This pricing model is then applied to the transfer of surplus water rights arising from agricultural water conservation schemes to industrial uses in the Southbank Ordos Irrigation Zone of the Inner Mongolia Autonomous Region. The results indicate that this pricing model could provide technical support to the scientific and reasonable pricing of water rights transactions in water-deficient areas and that it could play an active role in promoting the healthy development of future water markets.

Abstract Integrated water resources management (IWRM) is being implemented all over the world, considering its wide area of applications and flexible spatial scale. Scientists have found IWRM useful in an Indian context also where a coordinated development of water and land resources is sought as part of complete economic, social and environmental welfare. The paper presents the concepts of ‘Local IWRM’ planning applied to water conservation and management in a case study of Ur river watershed in Tikamgarh district of Madhya Pradesh (India). The Plan considers effective utilization of land, water and other available natural resources, linked to the vulnerabilities and livelihood opportunities in the geographical area. The IWRM Plan, designed in three sections – (1) water management, (2) land management, and (3) livelihood management – provides specific suggestions on the activities under these three themes as useful inputs to the District Irrigation Plan (DIP) of the Government. The proposed IWRM Plan intends to promote the component of water demand management in district level planning and is envisioned to be an ‘implementable’ planning document for district level government. Acceptability of the IWRM plan is potentially enhanced as the plan was developed through a participatory process, wherein all relevant stakeholders were consulted at different stages of development.

The Stability

The mining induced subsidence and strata deformation are likely to affect the stability of the aquiclude, resulting in loss of water resources in the mining area. In order to reduce the disturbance of coal mining to the overlying strata and to preserve the water resources in the coal mining area, the roadway backfill mining (RBM) method was trialed in Yuyang coal mine in Northern Shaanxi, China. Based on pressure arch theory and ultimate strength theory, a mechanical model was developed to analyze the stability of coal pillars. Then the maximum number of vacant roadways between the mining face and the backfilling face was determined according to the stability of coal pillar and filling body. The method to calculate aquiclude subsidence and deformation was also proposed. Furthermore, as indicated by FLAC3D numerical simulations, the maximum tensile stress subjected by the aquiclude was 0.14 MPa, which is smaller than its tensile strength; the horizontal deformation was 0.24 mm/m, which is also smaller than the critical deformation of failure. Field monitoring data demonstrated a maximum of 2.76 m groundwater level drop in the mining area after mining. The groundwater level was determined to be 4.45~10.83 m below surface, ensuring the normal growth of surface vegetation and realizing the water-conservation coal mining (WCCM).

The Impact

Water is a vital natural resource, demanding careful management. It is essential for life and integral to virtually all economic activities, including energy and food production and the production of industrial outputs. The availability of clean water in sufficient quantities is not only a prerequisite for human health and well-being but the life-blood of freshwater ecosystems and the many services that these provide. Water resource intensity measures the intensity of water use in terms of volume of water per unit of value added. It is an internationally accepted environmental indicator of the pressure of economic activity on a country’s water resources and therefore a reliable indicator of sustainable economic development. The indicator is particularly useful in the allocation of water resources between sectors of the economy since in waterstressed countries like South Africa, there is competition for water among various users, which makes it necessary to allocate water resources to economic activities that are less intensive in their use of water. This study focuses on economy-wide changes in South Africa’s water intensity using both decomposition and empirical estimation techniques in an effort to identify and understand the impact of economic activity on changes in the use of the economy’s water resources. It is hoped that this study will help inform South Africa’s water conservation and resource management policies
