Groundwater governance through electricity supply management: assessing an innovative intervention in Gujarat, western India by Shah, Tushaar, Bhatt, S., Shah, R.K., Talati, J.

“…It has also produced positive and negative impacts on medium and large farmers, while notably harming marginal farmers and the landless, who depend for their access to irrigation on water markets which have become much smaller, post-Jyotigram. …”

Water saving and economic impacts of land leveling: the case study of cotton production in Tajikistan by Abdullaev, Iskandar, Ul-Hassan, Mehmood, Jumaboev, Kahramon

“…The average annual net income from the laser field was 22% higher than that from the control field. The gross margin from the laser-leveled field were 16. 88 and 171% higher compared to that from the control field for 2004, 2005 and 2006, and on average was 92% higher. …”

Spatial modeling of risk in natural resource management by Jones, Peter G., Thornton, Philip K.

“…We found that low maize yields would become more likely in the marginal areas, whereas they may actually increase in some areas. …”

The challenges of inclusive cross-scale collective action in watersheds by Swallow, B.M., Johnson, Nancy L., Meinzen-Dick, Ruth S., Knox McCulloch, A

“…Water-users' associations and basin authorities may exacerbate these disparities and further marginalize already poor people. New statutory institutions may intentionally or inadvertently disempower effective customary local institutions. …”

Influence of driver ant swarm raids on earthworm prey densities in the Mount Kenya forest: implications for prey population dynamics and colony migrations by Schöning, C., Csuzdi, C., Kinuthia, W., Ogutu, Joseph O.

“…These results indicate that earthworm prey is highly abundant but at the same time so difficult to harvest that swarm raids exert only a marginal influence on earthworm populations. Longer-term studies would be required to determine whether earthworm populations are limited by swarm raids. …”

Effect of long-term un-treated domestic wastewater re-use on soil quality, wheat grain and straw yields and attributes of fodder quality by Simmons, Robert W., Ahmad, W., Noble, A.D., Blümmel, Michael, Evans, A., Weckenbrock, P.

“…In Faisalabad, if managed appropriately to address emerging salinity issues the contribution of wastewater irrigation to the achievement of MDGs 1 and 7 could be significant if adverse impacts remain as marginal as found in this study.…”

Assessing the impact of feed technology adoption by smallholders in sweet potato-pig systems in Sichuan, China by Lapar, Ma. Lucila, Toan, N.N., Zou, C., Liu, J., Li, X., Randolph, Thomas F.

“…Results indicate positive net benefit from adoption of sweet potato-based feeding technology, (i.e., gross margin estimates of silage adopters, are on average higher by 2-4 RMB per kg live weight of output than non-adopters of similar characteristics). …”

Phenotypic approaches to drought in cassava: review by Okogbenin, Emmanuel, Setter, Tim L., Ferguson, Morag E., Mutegi, R, Ceballos, Hernán, Olasanmi, B, Fregene, Martin A.

“…Cassava can be produced adequately in drought conditions making it the ideal food security crop in marginal environments. Although cassava can tolerate drought stress, it can be genetically improved to enhance productivity in such environments. …”

Quality and safety improvements in informal milk markets and implications for food safety policy by Lapar, Ma. Lucila, Deka, Ram Pratim, Lindahl, Johanna F., Grace, Delia

“…Estimates of economic benefits show positive effects in terms of increased average profit margins and value added. Sector level benefits as approximated from micro-level estimates of economic indicators show that traditional dairy value chain in Kamrup generates about 0.8 million rupees value added per day; this translates to an annual estimate of economic impact in Kamrup of at least US$ 5.6 million. …”

Modeling Water Management and Food Security in India under Climate Change by Islam A, Shirsath, Paresh Bhaskar, Kumer SN, Subash N, Sikka, Alok, Aggarwal, Pramod K.

“…Crop yield modeling showed decreases in irrigated and rainfed rice (Oryza sativa L.) yields under the future climate change scenarios, but the decrease is marginal for rainfed rice. Maize (Zea mays L.) yields in monsoon may be adversely affected by a rise in atmospheric temperature, but increased rain can partly offset those losses. …”

Brazil, Ethiopia, and New Zealand lead the way on climate-smart agriculture by Negra, Christine, Vermeulen, Sonja J., Barioni, Luís Gustavo, Mamo, Tekalign, Melville, Paul, Tadesse, Melaku

“…Ethiopia initiated innovative participatory watershed development programs, in partnership with numerous international institutions, which helped smallholder farmers to rehabilitate marginal land and break out of a poverty cycle. New Zealand has removed agricultural subsidies while partnering on research and development with the private sector as a way to ensure efficiency and resilience in an agricultural sector influenced by climate change and international trade dynamics. …”
