A socio-hydrological approach for incorporating gender into biophysical models and implications for water resources research.

Men and women interact with water resources and landscapes in different ways, and there are frequent criticisms that little research is undertaken across disciplines to address this issue. Biophysical scientists in particular struggle with how to integrate “gendered” water uses into models that are necessarily based on prevailing laws and equations that describe the movement of water through the hydrological cycle, independent of social constructs.

Seed Solutions for Food Security

Improved seeds of staple crops are a major leverage point for change in agriculture. By giving higher and more stable yields, they offer short-term benefits, which open the way toward a more profound transformation.

A review of environmental issues in the context of biofuel sustainability frameworks

Journal Articles & Books
Décembre, 2011

With the rapid growth of biofuel production and consumption and the proliferation of policy decisions supporting this expansion, concerns about the biofuel sector’s environmental and social impacts are increasing. Consequently, a range of actors – among them governments, multilateral institutions, nongovernmental organisations and multistakeholder industry groups – have created sustainability frameworks, some mandatory, others voluntary. This report examines how the most developed sustainability frameworks for feedstock production (including biofuels) address key environmental issues.

A major strategy towards addressing soil fertility depletion is the conservation and sustainable use of rhizobia that are able to fix nitrogen in the soil in association with legumes. The study assessed abundance and diversity of legume nodulating rhizobia (LNB) in soils collected from six different land use systems in Embu District, Kenya. The populations were estimated by the most-probable-number (MPN) plant infection technique using Macroptilium atropurpureum (DC.) Urban (Siratro) as the trap host species.

The abundance and diversity of soil mites was monitored along a gradient of land use types (LUTs) during the wet seasons in soils of Taita Taveta, Kenya. Sampling of mites from soils was carried out in eight LUTs which included maize-based system (Zea mays), coffee (Coffea Arabica), horticulture, napier grass (Pennisetum purpureum), fallow, pine (Pinus patula), cypress (Cypressus lusitanica), natural forest. LUT significantly influenced abundance, richness and diversity of the soil mites.

AEPS, Agricultura Específica por sitio, es un conjunto de métodos y herramientas que permiten colectar información de experiencias productivas comerciales, analizar datos con métodos novedosos y generar información que le servirá a productores, asistentes técnicos y entidades del sector agrícola, para tomar mejores decisiones sobre donde sembrar, cuando sembrar, que sembrar y que prácticas de manejo aplicar, cuando se cuenta con ciertas condiciones específicas de clima y suelo.
