The role of tenure in the management of trees at the community level: theoretical and empirical analyses from Uganda and Malawi by Place, Frank, Otsuka, Keijiro

“…Tenure is found to be linked to land-use and tree-cover change in both countries, though it is not necessarily the most important factor (e.g., population pressure is the key driving force for land-use change). …”

Sustainable agricultural development strategies in fragile lands by Scherr, Sara J., Hazell, Peter B. R.

“…Under population and market pressure, one can expect an endogenous process of intensification, through land improvements, tenurial and institutional changes and "re-ordering" of the landscape. …”

Changes in intrahousehold labor allocation to environment goods collection: A case study from rural Nepal, 1982 and 1987 by Cooke St. Clair, Priscilla

“…Given the increasing pressure on biomass resources in many developing areas and the common gender division of collection labor, there is concern that women in particular will bear the burden of increases in resource scarcity by having to spend more labor time and effort to collect forest products.…”

Genotypic screening for salinity tolerance of rice genotypes from Eastern and Southern Africa at seedling stage by Lutambi, Kefrine Kennedy, Henry, Amelia, De Ocampo, Marjorie, Chebotarov, Dmytro, Pedersen, Ole, Nchimbi-Msolla, Susan, Kilasi, Newton L.

“…The distribution of Saltol and phenotypically tolerant genotypes varied across Tanzanian agro-ecological zones, with the Coastal Zone showing a higher proportion of tolerant genotypes, possibly due to farmer selection pressure. However, ancestral population proportion correlated with decreased salinity tolerance. …”

Review: Improving global food security through accelerated plant breeding by Lenaerts, Bert, Collard, Bertrand C. Y., Demont, Matty

“…Climate change, urbanisation and land degradation are putting further pressure on the food supply. The multifaceted and self-reinforcing nature of these challenges calls for a fundamental transformation of the food system. …”

Rice responses to rising temperatures – challenges, perspectives and future directions by Jagadish, S.V.K., Murty, M. V. R., Quick, W. Paul

“…This review addresses (1) the importance of vapour pressure deficit under fully flooded paddies and increased vulnerability of rice production to heat stress or intermittent occurrence of combined heat and drought stress under emerging water‐saving rice technologies; (2) the major disconnect with high night temperature response between field and controlled environments in terms of spikelet sterility; (3) highlights the most important mechanisms that affect key grain quality parameters, such as chalk formation under heat stress; and finally (4), we model and estimate heat stress‐induced spikelet sterility taking South Asia as a case study.…”

Impact of resource-conserving technologies on productivity and greenhouse gas emissions in the rice-wheat system by Pathak, Himanshu, Saharawat, Yash S., Gathala, Mahesh, Ladha, Jagdish K.

“…However, because of increasing pressure of biotic and abiotic stresses in response to soil degradation and changing climate, crop productivity and farmers' profits are on a downward trend. …”

Genotypic Variation in Maintenance of Leaf Water Potential in Rice by O'Toole, J.C., Moya, T.B.

“…Visual scoring based on leaf rolling behavior appeared to be influenced by diurnal adjustment of the pressure potential. The integral for the day (—bar.day) was quite effective in separation of cultivars for maintenance of high leaf water potential throughout the day and highly correlated with ranking by visual scoring.…”

Governing Groundwater Irrigation in Bangladesh: Reviewing the Past and Looking Ahead for the Future by Sarkar, Anindita, Mukherji, Aditi, Mainuddin, M.

“…Groundwater governance in intensively irrigated agricultural regions of global south is receiving increased attention due to its growing complexities in responding to multifaceted challenges, of rapidly growing populations, demand for food production, increasing pressure on land and water resources, escalating energy use and cost of irrigation and uncertain climate futures. …”

China's past, present, and future food economy: can China continue to meet the challenges? by Rozelle, Scott, Rosegrant, Mark W.

“…However, the most likely scenario is for China to continue producing most of its own food while gradually increasing food imports without exerting severe upward pressure on the world markets. The paper concludes that China needs to prioritize investments in agricultural research for new technologies raising agricultural productivity, and mitigating rural environmental problems.…”

Decision-making among diverse interests: the use of future scenarios in local forest management policy, a proposed methodology by Wollenberg, Eva Karoline

“…As an umbrella concept, LFM included the rehabilitation of forests on degraded lands, management of natural forest, intensification of agroforestry to reduce pressure for use of natural forest, logging by communities, the sharing of management responsibilities with the state (co-management), nurseries, hunting and gathering by so-called traditional populations and wage employment for local people planting trees. …”

Secondary forest dynamics in the Amazon floodplain in Peru by Jong, W. de

“…The results show that processes of secondary forest formation are influenced by advancing market access, changes in the dominant land type as a result of river floods, and population pressure when villages become older. As villages age farmer's holding tend to become smaller. …”
