Mainstreaming water quality in River Basin Management in the Brantas River Basin, Indonesia:abstract submitted to the International Conference Water Science for Impact

Over the past 20 years, water quality in Indonesia has deteriorated due to an increase of water pollution. Research and analysis is needed to identify pollution sources and assess contamination in Indonesian water resources. Water quality management is not yet sufficiently integrated in river basin management in Indonesia, which mainly focuses on water quantity. Women are comparatively highly impacted by failing water resources management, but their involvement in decision making processes is limited. Water quality deterioration continues to increase socio-economic inequality, as it are the most poor communities who live on and along the river. The uneven water quality related disease burden in Brantas River Basin widens the socio-economic gap between societal groups. In the Brantas region, cooperation and intention between stakeholders to tackle these issues is growing, but is fragile as well due to overlapping institutional mandates, poor status of water quality monitoring networks, and limited commitment of industries to treat their waste water streams. The existing group of Indonesian change makers will be supported by this project. Three Indonesian and three Dutch organisations have teamed up to support negotiation platforms in order to deal with institutional challenges, to increase water quality monitoring capacity, to build an enabling environment facilitating sustainable industrial change, and to develop an enabling environment in support of community concerns and civil society initiatives. The project builds on integrated water quality monitoring and modelling within a framework of social learning. The strong consortium will be able to build links with civil society groups (including women, farmer and fisher unions) in close cooperation with local, regional and national Indonesian government institutions to clean the Brantas river and secure income and health for East Java’s population, in particular the most vulnerable groups

Securing the Harvest for the Smallholder Farmer in Rwanda: Fragmented or Consolidated Farmland Use?

The year 2007 marked the beginning of a journey to secure food in Rwanda. The country introduced the Crop Intensification Program (CIP), which promotes the farmland use consolidation (LUC). This study assesses the effect of farmland use changes on the agriculture production. We collected data at four research sites and considered three agriculture years to assess the effect of the fragmented or consolidated farmland use on the harvest. The study confirms that the CIP/LUC program converted perennial crops, mainly banana plantations, into seasonal crops, which were prioritized by the program. Overall, we conclude that the shift in farmland use has created an increase in both the harvest and monetary yields of the prioritized crops. However, within that general trend, we observe differences: farmers with smaller and/or fewer farm plots did not realize as great a yield increase as those who joined the CIP/LUC program with larger and/or multiple farm plots. While contributing to an understanding of the ongoing agriculture transformation program in Rwanda, this study followed a statistical approach that could be used by new studies assessing the benefits and outcomes of development policies

Structuring properties of irrigation systems: Understanding relations between humans and hydraulics through modeling

Irrigation systems were clearly important in ancient times in supplying crops with water. This requires physical distribution facilities and socio-political arrangements to coordinate between actors. Resulting systems are highly diverse, and are being studied extensively within archeology and history. Whether initiated by a central authority or emerging from small-scale initiatives, irrigation systems are shaped through activities of individuals, households, and small groups into patterns and landscapes. This article discusses how hydraulic modeling techniques are powerful methodologies to study such irrigation development. Modeling daily interactions by agents and water fluxes will build better understanding of irrigation systems as anthropogenic landscapes. Three case studies will be used to illustrate this argument. A current irrigation system in Arequipa, Peru, shows that one can relate irrigation infrastructure and social action. A second case from Peru on a pre-Colombian irrigation system suggests that one can link irrigation system, water flows, and settlement. In the third case in the Jordan Valley, this possible link between irrigation and settlement is further studied.Water ManagementCivil Engineering and Geoscience
