Gender Transformative Impacts from Watershed Interventions: Insights from a Mixed-Methods Study in the Bundelkhand Region of India
This study examined gender perspectives on water security by exploring an integrated water management approach
for agriculture, livestock, and human consumption. The data were generated in a watershed project to enhance
drought resilience of farming through groundwater recharge and agroforestry interventions in the water-scarce Bundelkhand
region of Uttar Pradesh in central India. Post-intervention, a quantitative survey and qualitative gender and social
analysis tools were applied to understand the benefits of the interventions for women, men, and the community as a whole.
Quantitative data were collected from 700 individuals in five villages (three treatment villages and two villages where watershed
interventions were not implemented). In addition, 33 semi-structured interviews and eight focus group discussions were
conducted to understand local gender norms at the project sites. Data analysis revealed that the community benefits accrued
from the watershed interventions included increased crop productivity and diversification of agriculture and livelihoods.
However, strict patriarchal norms restricted the visibility, mobility, and communication of women within the household and
community during the interventions. Considering gender diversity, this study identifies that women can benefit from participating
in watershed interventions and provides a deeper understanding of the constraints and barriers to women’s participation
in such projects, including economic, social, and cultural factors. The construction of check dams reduced women’s time
per day for fetching water by about 29%. Groundwater level increases reduced the effort required of women to draw water
from open wells and hand pumps. Female education is a significant factor related to the benefits of watershed interventions,
and regression analysis indicated that households with higher levels of education of adult women were significantly more
likely to benefit from the interventions than other households. To avoid perpetuation of the exclusion of diverse local
knowledge and gender inequality at the community level,
mechanisms must be developed and adjusted continuously
such that whole communities, including men and women, are
empowered to participate in the decision-making process at
various levels and for different purposes. When implementing
watershed projects in a highly patriarchal context, as in the
Bundelkhand region where women are hidden behind the
strong presence of men, advocacy of behavioral change
communication must be implemented regularly. The community
needs to be sensitized toward systematic and gendersensitive
institution building, social engagement, and capacity
development for local as well as global water security
Process Documentation Research and Impact of Community-Driven Development Grants Research in Rural India, Socioeconomics Discussion Paper Series 34
In 2011 ICRISAT gave experimental grants to six dryland villages targeted by the “Village Dynamics Studies in South Asia” (VDSA) project. Two villages were located in Telangana state (undivided Andhra Pradesh) and four in Maharashtra state. A grant of USD 7,000 (Rs. 315,000) was given to each villages to assess the role of local governance and institutions on agricultural performance, and to evaluate development pathways. The community was free to decide where and how to use the grant. Using the Process Documentation Research (PDR) framework, this report documents the activities of the ICRISAT-VDSA project team and the community implementation committee in using the grant, and lessons learned in the process. We also estimated the number of beneficiaries and the economic benefits from the grant. In two villages, the annual economic benefits from the grant were almost equal to the total grant expenditure. In five villages, the cumulative benefits over the last four years exceeded the total value of the grant. Unlike other publically-funded projects, large numbers of households from minority and socially weaker sections also benefited. The results suggest that, given the opportunity, local communities can effectively execute local infrastructure development projects through need-based collective action, while lowering the transaction costs of community action. By involving local community members in planning and implementing projects, the village grant provided benefits to a large number of households and generated substantial economic benefits. The experiment provides useful lessons for scaling-out village grants to other project villages, and for rural development agencies in India and elsewhere

Modeling the Back Contact of Cu2ZnSnSe4 Solar Cells
International audienceIn this paper, we analyze the theoretical impact of the Molybdenum (Mo) back contact and the MoSe2 interfacial layer on the performances of a Cu2ZnSnSe4 (CZTSe)-based solar cell. MoSe2 layers are formed spontaneously in the Mo/CZTSe interface during the annealing of the absorber, but disagreeing interpretations about their actual role in affecting the device figures of merit (V-OC, J(SC), FF, and eta) have been proposed in the literature. In our approach, we have simulated three structures presenting different conditions at the back contact: ideal-contact/CZTSe (flat-band), Mo/CZTSe, and Mo/MoSe2/CZTSe. For these three layers, an accurate explanation of the selection of critical material parameters is given. The numerical simulations, performed with SCAPS 3.2.01, show that the low values of Mo work function (<= 4.95 eV) would have a strong detrimental effect on the V-OC and FF of the cell if no interfacial layers were present at the Mo/CZTSe interface. On the other hand, a beneficial effect of the MoSe2 layer on the V-OC of the device is demonstrated when this layer is included in the structure. This trend is confirmed by experimental measurements. The expected band diagram of the full ZnO/CdS/CZTSe/MoSe2/Mo structure is provided
