The Hon’ble Juvenile Justice Committee of the Orissa High Court directed the Government of Odisha to have a systematic examination of the situation of children in conflict with law across the State. On request of the State Government, a study was commissioned by UNICEF Odisha and SIGMA Foundation was engaged for the assignment through a process of competitive bidding. The study has five objectives:
• Document the socio-economic profile, family background, and developmental history of the CCLs.
• Identify the causal factors- Individual, family, environmental, and structural factors.
• Examine the pattern of offences, including POCSO and recidivism.
• Understand children’s experience with the JJ system and perspectives shared by the parents and JJ system staff.
• Recommend a way forward

The study involved visiting all the 15 Homes for the children who allegedly come in conflict with law (seven Observation Homes, seven Special Homes, and one Place of Safety) spread across the districts of Sundargarh, Angul, Boudh, Kalahandi, Ganjam and Malkangiri. A mixed method approach with Interpretative Phenomenological Analysis (IPA) was adopted for the study. Data collection involved – analyses of data from the 151 Case Files of the children in Conflict with Law (CCL) including the Social Investigation Reports (SIRs) which were available at the Homes visited, interaction with 300 alleged juvenile offenders who were at those homes during the visits and In-depth Interview of 64 of them selected purposely for representing various types of Cases, In-depth Interview of 30 parents and 4 siblings of the alleged CCLs and 64 key officials like judges, police officials, lawyers, officials of the homes and other duty bearers associated with the juvenile justice system.

A presentation on the key findings was made before the Hon’ble Juvenile Justice Committee on the 21st May, 2026 by the President, SIGMA Foundation and other officials of the organization. The findings were also presented before the Principal Secretary Women and Child Development Department of the Government of Odisha on the same day. Based on feedback received from the said discussions as well as from UNICEF, the report has been finalized and submitted to UNICEF for further necessary action. This is a unique study and is likely to be the first of its kind about the CCL. It brings out several issues which will help policy makers to address various issues of the children who come in conflict with law.

SIGMA Foundation presented its innovative model for domestic greywater recycling at the 15th Hanseatic India Colloquium, held in Hamburg, Germany, on 29 June 2026. The conference, themed “Indo-German Dialogue: Circular Wastewater Management for Sustainable Development,” brought together researchers, practitioners, and policymakers from India and Germany to exchange knowledge and experiences on sustainable water management.

Dr. M. N. Roy, President of SIGMA Foundation, was invited by the organizers to present the Foundation’s pioneering work on decentralized greywater recycling for sustainable agriculture.

During his presentation, Dr. Roy highlighted a demonstration project implemented in Jangipara Gram Panchayat with support from Sign of Hope, Germany. The system uses a simple filtration arrangement using sand, gravel and charcoal to treat domestic greywater, making it suitable for irrigation. Laboratory analysis showed that the coliform level in the treated water was reduced from 3,300 MPN/100 ml to 49 MPN/100 ml, which is well below the acceptable limit of 1,000 MPN/100 ml for irrigation.

The treatment unit recycles approximately 250 kilolitres of greywater annually, providing year-round irrigation to a 5-kattha (0.165-acre) agricultural plot. This has enabled the cultivation of leafy vegetables and other crops throughout the year, generating an annual income of around ₹80,000 for the participating household.

An additional benefit of the system is its ability to retain a portion of the nutrients present in domestic greywater, including phosphates and nitrates. These recycled nutrients have contributed to an estimated 50% increase in the yield of leafy vegetables, such as spinach and water spinach. Since the treated water flows to the field entirely by gravity, the system requires no external energy for pumping or water transport, making it both environmentally sustainable and cost-effective.

The project demonstrates how a simple, low-cost technology can strengthen climate resilience in agriculture by providing a reliable source of irrigation without extracting groundwater. At the same time, it enhances crop productivity through nutrient recycling and supports circular resource management.

SIGMA Foundation recently conducted a study with support from Landesa, an organization which works on land rights across the world. To examine the land rights of tribal women and land related conflicts that adversely affect the tribal women. The study was for tribal women living in Jharkhand. The study included analysis of secondary data, including media on land disputes, and collection of primary data from Lohardaga and Gumla districts. The study sought to understand the current status of land rights for tribal women in the region, how customary practices affect their land rights, to what extent witch hunting is associated with land issues and how administration of land protects the rights of tribal women.

The study aimed to understand the legal framework, map different types of land issues and associated violence, and examine key land regulatory frameworks — including the Chotanagpur Tenancy (CNT) Act, Santhal Parganas Tenancy (SPT) Act, Panchayats (Extension to Scheduled Areas) Act (PESA), and the Forest Rights Act (FRA) — with the goal of developing a policy brief to support programmatic and policy engagement.

SIGMA’s research team began with an intensive secondary literature review, systematically examining over 400 Hindi newspaper articles on land related violence across seven regional newspapers published between 2023 and 2025, all related to land violence. The patterns that emerged were corroborated through an extensive review of secondary literature on land rights, forest rights, land governance systems, and their implications in Jharkhand. Together, these two streams of evidence provided a clearer picture of the present status of land rights in the CNT region.

The research team subsequently conducted field validation in Lohardaga and Gumla, engaging with a range of stakeholders — from key government officials, police to women survivors of land rights violations and facing allegations like witchcraft and documented case stories. The findings have been compiled into a report which also include key recommendation to be acted upon in the short, medium and the long-term.

SIGMA Foundation is glad to have worked in partnership with Landesa on this important stud and to bring out new evidence on a subject which is under-researched and less understood.

The ADDCWES centre of IIEST Shibpur, which is dedicated for advancement in water and environment studies is implementing a pilot project on rainwater harvesting in Jhalda I block of Purulia district in partnership with SIGMA Foundation. The progress of the project was reviewed on the 29th May at IIEST, Shibpur.

The meeting was attended by key dignitaries including Prof. Arun Deb, Governing Body Member, ADDCWES, IIEST Shibpur; Prof. Anirban Gupta, Centre Director, ADDCWES and Dean – International Relations & Alumni Affairs, IIEST Shibpur; Er. Shyamaprasad Dutta, Governing Body Member and Dr. M. N. Roy, Founder-President, SIGMA Foundation, Dr. Debasri Mukherjee, Assistant Director – WASH and other members of SIGMA Foundation and IIEST.

The project is being designed as a pilot initiative promoting use of locally available materials, which is to evolve into a scalable and replicable model for water-stressed regions for which the Gram Panchayat will also be capacitated. The design is going to be finalized after site validation within a month.
The project places a strong emphasis on applied, field-based research to understand various factors that can provide long-term sustainability of the project and to measure the impact on local people. A critical component will be groundwater monitoring, where local Gram Panchayat representatives will be trained to record and manage rainfall and groundwater table data over time, enabling evidence-based water conservation initiatives. Community engagement will be central, with awareness campaigns and training on climate-smart agriculture and natural farming practices. Together, these research efforts aim to generate actionable insights, strengthen community resilience, and create a replicable model for climate-adaptive water resource management.

The Juvenile Justice Committee (JJC) of the Odisha High Court had observed that the number of children coming into conflict with law was increasing. They wanted to know the reason behind the same and felt that it needed a detailed study. UNICEF Odisha State Office and the Department of Women & Children (WCD) of the Government of Odisha supported the study and engaged SIGMA Foundation through an open selection process.

No similar study had previously been undertaken in the country, and conducting such a study was a major learning experience for SIGMA Foundation. An exploratory phenomenological methodology was adopted and both quantitative and qualitative data were collected from a sample of 64 CCLs representing different types of alleged offences from among around 300 CCLs who were in different homes (Observation Homes, Safe Homes and Places of Safety) across the entire state during the time of the visits and documents (Social Investigation Reports) of around 150 CCLs available at the homes were examined to understand their social background. Criminal Propensity Scores of 64 sampled children were estimated using a structured tool validated through a pilot survey. Qualitative data were collected from around 150 stakeholders such as the Parents of the CCLs, their Siblings and Peers, Probation Officers, Counsellors, Superintendents of the Homes, Security personnel, Principal Magistrates and Members of the Juvenile Justice Board, Police officials, Lawyers, District Child Protection Officers, Member Secretary State and District Legal Service Authorities etc.

The data were analysed and the key findings on the socio-economic background of the CCLs, demographic features, nature of offences allegedly committed, progress of disposal of the cases, status of rehabilitation and reintegration of the children etc. were presented before the Juvenile Justice Committee. Members of the study team namely Dr Satarupa Dutta, Ms Sayantani Banerjee and Ms Srishti Saha led by the President Dr M. N. Roy presented the findings before the three Hon’ble Judges constituting the JJC of the Odisha High Court. Commissioner-cum-Secretary of the Women & Child Development Department, Director of the Department, ADG Police looking after juvenile offences, Chief of Field Office, UNICEF Odisha and Child Protection Specialist of Odisha UNICEF Mr Manna Biswas, who has been coordinating the study, were present. The formal report will be submitted by early June 2026.

SIGMA Foundation took up evaluation of two livelihood and climate change related projects funded by Sign of Hope Germany. Based on analysis of secondary data and those collected during the evaluation, a paper “Hoping to return? Migration and ecological balance in the Sundarbans” has been authored by Dr Sanjukta Das and Dr M.N.Roy of SIGMA Foundation and Mr Dirk Baldenhofer of Sign of Hope. The paper has been published online (https://doi.org/10.1080/17565529.2025.2610696) in the journal CLIMATE AND DEVELOPMENT by Taylor & Francis, a highly reputed journal based in the United Kingdom. This paper studies whether permanent evacuation is the optimal coping strategy, from the point of view of both the inhabitants as well as the environment, in the Sundarbans, to inform the broader debate on climate induced migration worldwide. Results show that while migration leads to a deterioration of the ecological balance by 1% in the region, it also has a positive impact on the level of hopefulness experienced by low-income migrants. However, the majority of migrants express a desire to return to their native place, regardless of income groups. The results speak to the importance of making scientific advances in effective coping strategies in the face of the growing scale of climatic disasters, such that migration is a voluntary choice rather than a compulsion.
